Abstract:

This keynote will give an overview of hydrogels use for regenerative dental medicine. Hydrogels are three dimensional networks that have the ability to retain large amounts of water. More than 90% of the body is composed of macromolecules physically or chemically crosslinked in high water content and soluble compounds. Hydrogels have structural similarities with extracellular matrices (ECMs) and versatility that make them the ideal candidates in tissue engineering, drug delivery systems, and  specifi c medical devices. 20 years ago, we designed injectable bioactive suspensions in water of calcium phosphate ceramics for bone and periapical regenerations. Because of leakage of these suspensions, we focused on injectable hydrogels before to set in situ by physical or chemical crosslinking to form 3D scaff olds. Finally, we set up a platform to develop a series of innovative hydrogels for bone, periodontal and endodontic tissue regeneration. We based our strategy on polysaccharides macromolecules because they are renewable materials, that originate from biological sources and generally are biocompatible, non-toxic and biodegradable. We developed a family of silanized and methacrylated macromolecules able to react forming biocompatible hydrogels. Th e silanized polymer are self-setting hydrogel able to covalently crosslink under pH variation, without addition of toxic crosslinking agent. Th e methacrylated polymers allow the in-situ photo crosslinking under standard dentistry lamp using cytocompatible photoinitiators. All these macromolecules could be combine in multicomponent hydrogels, representing a strategy for improving mechanical properties of biomaterials or to tailor particular properties to meet specifi c needs. For mineral scaff olding, we realized composites of calcium phosphates particles or cements with hydrogel, increasing the ductility and creating macroporous scaff old to propose foam bone cements. For endodontic applications we started to explore crushed dentine in high pH hydrogel for local autologous growth factors release and to investigate specifi c galenic formulation for dual molecules delivering. Future perspectives of our strategy are moving towards 3D printing and bio printing techniques. We will use our hydrogel platform to prepare tunable (bio) inks well adapted for specifi c applications in personalized dental medicine.

Abstract:

Introduction: In the field of oral and maxillofacial surgery, the removal of impacted third molars is considered a routine procedure. However, it is also associated with variable post-operative consequences like pain, swelling and trismus. Corticosteroids are some of the most common pharmaceutical agents employed to manage these complications.
 
Aim: The aim of the present study was to assess preemptively the effectiveness of oral corticosteroids used in controlling the above sequalae after third molar surgery.
 
Methods: A PubMed, Medline, Scopus, Sciencedirect, EBSCO and Google scholar search was carried out of all controlled clinical trials on the eff ects of oral corticosteroids on pain, swelling and trismus aft er lower third molar surgery. The review was limited to studies published over the last 10 years (2008-2017).
 
Results: The most relevant randomized controlled trials were selected from among 32 articles.
 
Conclusions: The results of this study suggest that a single preoperative weight-dependent administration of oral corticosteroids is a safe and effective concept for diminishing postoperative discomfort, pain intensity, and the total intake of analgesics aft er third molar surgery.
 

Hassan Koshak

Title: Short implant vs. sinus elevation
Speaker
Biography:

Hassan Koshak received his Master of Science in Dentistry (MSD) and a Clinical Certificate in Periodontics from Riyadh Colleges of Dentistry and Pharmacy (2009-2012) Riyadh, Kingdom of Saudi Arabia (KSA) with honours. He received his Advanced Education in General Dentistry (AEGD) from University of South California School of Dentistry (2006-2008); Bachelor of Dental Medicine and Surgery (BDS) from Faculty of Dental Medicine and Surgery, King Abdul-Aziz University, Jeddah, KSA. He is a Consultant in Periodontics and Implant Dentistry. He is the Head of the Dental Department and Dental Educator at Comprehensive Specialized Polyclinic, Ministry of Interior Security Forces Medical Services, Jeddah, Kingdom of Saudi Arabia since 2016. He received Saudi Fellowship in Dental Implant from the Saudi Commission for Health Specialties (2014-2016). He received a Saudi Board in Periodontics from the Saudi Commission for Health Specialties (2012-2014).

Abstract:

Clinical choice of the most appropriate implant therapy modality should be based on assessment of the residual alveolar bone height, width, and sinus morphology with a cone beam computed tomography (CBCT) scan, current scientific evidence, surgical skills and experience of the surgeon, and the patient’s preferences. Following a good surgical protocol and excellent oral hygiene maintenance program are fundamental elements in achieving a successful and predictable outcome. The available evidence on short dental implants in early research was not significant comparing with the longer dental implants; the surface treatment is improving now than before for this reason. The use of short implants allows treatment of patients who are unable to undergo complex surgical techniques for medical, anatomic or financial reasons. By reducing the need for complex surgeries short implants reduce morbidity, cost and treatment time. Recently short implants offer a less invasive treatment alternative in resorbed ridge cases.

Afnan O Al-Zain

King Abdulaziz University, KSA

Title: Influence of curing unit beam profile on polymerization patterns within a resin-matrix composite
Speaker
Biography:

Afnan O Al-Zain completed her BDS Degree from Faculty of Dentistry, King Abdulaziz University (KAU), Kingdom of Saudi Arabia; MSD Degree from Indiana University School of Dentistry, USA, and PhD Degree from Indiana University. She is an Assistant Professor in the Division of Operative and Esthetic Dentistry Faculty of Dentistry at KAU; is a Co-Course Director for third year BDS students. Her passion is to make an impact that would benefit society. Her research methodology creates new insight for understanding polymerization pattern to improving dental healthcare. She strives to contribute significantly to the direction of oral health care by engaging in research and dental education.
 

Abstract:

Statement of the Problem: Fracture failure of resin-matrix composite (RMC) increased in the past decade from 29.5%-39.1% due to multiple factors that may include non-uniform polymerization across the RMC surface. Investigating polymerization patterns within the bulk of a RMC can contribute to greater understanding of fracture etiology.

Purpose: The purpose of this study was to investigate the relationship of an irradiance-beam-profile area from different lightemitting-diode (LED) curing-units on the degree of conversion (DC) and Knoop microhardness (KH) and cross-link density (CLD) uniformity within a RMC at two clinically relevant distances and explore the correlation among them.

Methodology: Irradiance-beam-profiles were generated from six light-curing units (LCUs); one quartz-tungsten-halogen, two single and three multiple-emission-peak LED units and combined with the corresponding power measurements. The radiant exposure was maintained, and a mapping approach was used to investigate DC (micro-Raman spectroscopy), KH (hardness tester) and %KH reduction as an indicator of CLD (ethanol-soft ening method) within a nano-hybrid RMC increment at various depths cured at two light-tip distances. The localized irradiance correlation with the corresponding DC, KH and %KH reduction was explored.

Findings: Non-uniform DC, KH and %KH reduction was observed within the specimens and localized polymerization discrepancies were significant at specific depths and points, which did not follow a specific pattern regardless of the LCU or curing distance. A mapping approach within the specimens provided detailed polymerization characterization. Localized irradiance was weakly correlated with the corresponding DC, KH and %KH reduction on the top RMC surfaces at both distances. Polymerization of the RMC investigated did not reflect the LCU irradiance pattern at the area assessed, and no LCU demonstrated uniform polymerization at all points for the measurements investigated at both distances. Therefore, the LCUs explored do not result in uniform polymerization, which may potentially increase the risk of RMC fracture.

Title: Zirconia V lithium disilicate: Dawn of ceramic justice
Speaker
Biography:

Adnan A Ishgi has completed his Certificate of Advance Graduate study in Prosthodontics and Doctorate of Science in Biomaterials from Boston University (Boston, USA) and Masters in Medical Education from King Saud bin Abdulaziz University for Health Sciences (KSAU-HS). He is the Director of the Postgraduate residency training programs at the Saudi National Guard-Health Affairs; Chairman of the Physician Scholarship Selection Committee at KSAU-HS, Chairman of the Prosthodontic Curriculum Committee at the Saudi Commission of Health Specaialties (SCFHS).

Abstract:

New technologies and materials for the restoration of oral function and esthetics are continuously being introduced to modern dentistry. Traditionally, metal-ceramic restorations were the gold standard for crowns and fixed partial dentures because they provided outstanding performance; nevertheless, these restorations do not always provide optimal esthetics. Dental researchers and manufacturers have been involved in an on-going race to develop a durable, more esthetic replacement for the successful metal-ceramic restoration. Many attempts have been made in recent years to offer a strong, highly esthetic allceramic restoration. Currently, zirconia and lithium disilicate (IPS e.max) are among the most popular materials available for this purpose. The market is replete with advertisements for both zirconia and lithium disilicate, but which material is better, and under which circumstances? This evidence-based, clinically-oriented presentation will highlight the indications, contraindications, advantages and disadvantages of these two ceramic materials with guidelines for selecting the most desirable ceramic material based on the clinical conditions.

Abstract:

Several decades ago, aesthetic dental needs were not on top of patient interest, but recently aesthetics has taken its rightful place along with functionality due to the increasing knowledge of the field and also advancement in materials and technologies. Consumers now are aware of effect of esthetics of their teeth, on their wellbeing, their acceptance by others, their success in work and in relationships, and their emotional stability informed by books and ongoing media coverage. These same consumers have their unique cases, which depend on pre-existing dental condition, extraoral and intraoral factors, knowledge, expectations, and even financial boundaries. All the previous factors along with clinical and laboratory materials and methods affect the final esthetic outcome of dental treatment. This presentation will discuss all the previous factors, which aim at reaching the aesthetic treatment needed by both patients and dentists.

Title: Tooth brushing schemes in schools, tackling inequalities in health
Speaker
Biography:

Purpose: This paper assesses the effectiveness of a tooth brushing activity delivered in primary schools in the Emirate of Dubai, UAE as part of a preventive program. The tooth brushing activity was designed with the intention of improving the oral health of young children and emphasizes on the importance of daily good oral hygiene habits.

Materials & Methods: The evaluation was based on a pre and post visible plaque index examination, an interview with the school nurse responsible for the follow up and a feedback questionnaire for the parents.

Results: Children accepted the activity and they enjoyed participating in daily tooth brushing. Children were more aware of the importance of daily brushing and the consequences of poor oral hygiene. The activity was more successful when the school administration and school nurse embraced and accepted the idea of their students brushing daily in schools. Feedback from the parents showed children involvement in such an activity were more keen to brush at home and had a positive infl uence on their siblings.

Conclusions: The results of the activity suggest that tooth brushing in schools could be an effective method to encourage and enforce good oral hygiene habits. This paper gives an overview on how this could be implemented and the possibility of setting up policies and guidelines to govern its application in all schools of Dubai.

Hafiz Taha Mahmood

Aga Khan University Hospital, Pakistan

Title: Correlation between the atlas morphology and the maxillo-mandibular divergence pattern
Speaker
Biography:

Hafiz Taha Mahmood has completed his BDS in 2012 from Dow University of Health Sciences, Karachi, Pakistan. He has published 5 research papers in local and international journals in the field of Dentistry. Currently, he is working as Resident in the Department of Orthodontics in Aga Khan University Hospital, Karachi, Pakistan.

Abstract:

Introduction: Early identification of the maxillo-mandibular divergence pattern of patients allows orthodontists to attain maximum improvement in skeletal relationships through growth modification and avoid orthognathic surgery.

Aim: Therefore, the aim of this study is to evaluate the correlation between atlas morphology and maxillo-mandibular divergence.

Materials & Methods: A cross-sectional study was conducted on the pretreatment lateral cephalograms of 208 subjects aged 18 to 25 years. The atlas parameters were categorized into atlas dorsum, anteroposterior and ventrum and measured on View Pro-X soft ware. Various maxillary (FPPP, SNPP and FHPP angles) and mandibular (SNGoGn, saddle, articulare, gonial, sum of posterior and Y-axis angles) parameters were used to evaluate the divergence pattern of the individual. The Mann-Whitney U test was used to compare atlas and maxillo-mandibular parameters between genders. Spearman correlation was used to correlate atlas and maxillo-mandibular parameters across genders. A p-value≤0.05 was considered as statistically significant.

Results: Statistically significant differences were found between various atlas and maxillo-mandibular parameters between genders. With atlas dorsum, the saddle angle (r=-0.3) in males whereas gonial (r=-0.2), Y-axis (r=0.1) and SNPP (r=-0.2) angles in females showed significant weak correlation. With atlas anteroposterior, saddle (r=-0.2), articulare, (r=0.2), SNPP (r=-0.2) and FHPP (r=-0.3) angles in males showed significant weak correlation. However, only the SNPP angle (r=-0.2) in females showed a signifi cant weak correlation with atlas ventrum.

Conclusions: A weak correlation was found between atlas parameters and various maxillo-mandibular angular parameters in both genders. Therefore, atlas morphology cannot be regarded as a good predictor of future maxillo-mandibular divergence pattern.

Title: The evaluation of cervical spine posture after functional therapy with twin block appliances: A retrospective cohort study
Speaker
Biography:

Adeel Tahir Kamal completed his Bachelor’s in Dental Surgery from Altamash Institute of Dental Medicine, Karachi, Pakistan in the year 2012. He is a Dentist by profession. Currently, he is a Postgraduate Trainee at Aga Khan University Hospital, Karachi, Pakistan.
 

Abstract:

Introduction: It has been postulated that a change in cervical posture occurs due to forward repositioning of the mandible.
 
Objectives: Therefore, the objective of this study was to compare the cervical spine posture between subjects with and without functional appliance therapy.
 
Materials & Methodology: A retrospective cohort was conducted using pre and post functional therapy cephalograms of orthodontic patients. A total of 60 subjects were equally divided into two groups i.e. those who underwent treatment with a TB functional appliance and a control group selected from the Bolton Brush study. Three established sagittal and seven cervical vertebral parameters were compared between the groups. Wilcoxon signed-rank test was used to compare pre and post functional mean angular measurements. Mann-Whitney U test was used to compare the mean changes in cervical parameters between the groups. 
 
Results: A significant difference existed between pre and post functional SNB (p<0.001) and ANB angles (p<0.001) showing a change in maxillomandibular relationship. Comparison of mean changes in angular measurements between the two groups showed a significant difference (p=0.033) in the sella-nasion to odontoid process tangent (SN-OPT) angle. SN-OPT angle predicts the probability of developing an altered cervical posture with the TB appliance is 1.92 times greater than without the TB appliance. 
 
Conclusions: SN-OPT angle can predict a change in skeletal relationships following treatment with the TB functional appliance. The TB causes the craniocervical posture to be more upright. Subjects with reduced vertical dimensions have greater change in cervical posture.

Title: Awareness of dentists regarding immediate management of dental avulsion
Speaker
Biography:

Kamil Zafar has completed his Bachelor’s Degree in Dental Surgery from Dow University of Health Sciences, Karachi, Pakistan. He is currently pursuing Fellowship in Operative Dentistry at Aga Khan University Hospital, Karachi, Pakistan. He has published three papers in reputed journals.
 

Abstract:

Background: Of all traumatic dental injuries, dental avulsion accounts for 16% of injuries. Immediate intervention is key to the long-term success of an avulsed tooth. Inadequate management of these cases leads to serious esthetic implications causing social embarrassment to the patient and ultimately an increasing the cost of defi nitive prosthodontic treatment.
 
Objectives: The objective of this study is to assess the knowledge of practicing dentists in Karachi regarding immediate management of dental avulsion. Methods: A cross-sectional study was conducted in various dental colleges and teaching hospitals of Karachi, Pakistan from October to November 2016. A total of 333 dentists meeting the inclusion criteria were recruited to fi ll a self-administered questionnaire. Questions related to knowledge and practice regarding immediate management of dental avulsion was asked and then responses were categorized as good knowledge, moderate and poor knowledge. SPSS version 22 was used for data analysis. Chi-square test was applied to fi nd the association of knowledge with diff erent variables (specialty, qualifi cation and years of practice).
 
Results: Only 11% dentist had good knowledge, while 46% had moderate and 43% had poor knowledge regarding immediate management of dental avulsion. Th ere was statistically signifi cant association of knowledge with specialty and qualifi cation. Dentists belonging to specialty of operative dentistry had relatively better knowledge in comparison to other specialties.
 
Conclusions: Within the limitations of the study, we conclude that the knowledge of dentists in Karachi, Pakistan regarding immediate management of avulsion is inadequate. Knowledge was signifi cantly associated with specialty and qualifi cation of dentist.

Muhammad Ashfaq Younus

Aga Khan University Hospital, Pakistan

Title: Determination of mean mesiodistal width of canines in patients reporting to a tertiary care hospital
Speaker
Biography:

Muhammad Ashfaq Younus completed his graduation from Karachi Medical and Dental College in 2011 and then started his Postgraduation in Orthodontics in 2013 from the same college. He is currently working in the Department of Orthodontics, Aga Khan University Hospital, Karachi, Pakistan.
 

Abstract:

Introduction: Canines are the most important tooth in the oral cavity both functionally and anatomically so whenever an orthodontic treatment is completed canines are given most importance. Since the prevalence of maxillary canine impaction is found to be between 1-3% so in cases with canine impactions cuspidization of premolars is done. Canines have been demonstrated to display greater sexual dimorphism in crown size than any other tooth. Keeping those facts in mind one should know the average size of both maxillary and mandibular canines in a given population.
 
Objectives: Th e objective of this study is to determine mean mesiodistal width of maxillary and  mandibular canines.
 
Methods: Data was collected from patients referred to the Department of Orthodontics, Karachi Medical and Dental College, (Karachi Pakistan). Verbal informed consent was taken from the patients. Mesiodistal width of maxillary and mandibular canines were measured on the casts using digital Vernier caliper. All the fi ndings were recorded on a predesigned proforma.
 
Results: A total of 131 patients were screened for this study. Th e average age of the patients was 18.90±1.523 years. Mean mesiodistal width of maxillary canine was found to be 8.502mm with standard deviation of 0.615mm. Mean mesiodistal width of mandibular canine was found to be 7.444mm with standard deviation of 0.764mm.
 
Conclusions: Th is study showed that the canines are not mirror images of one another. Sexual dimorphism was also found in the mesiodistal widths of maxillary and mandibular canines. It can also be concluded from the study that males have greater mesiodistal widths of canines than females.

Title: Marginal bone loss around cement and screw-retained fixed implant prosthesis
Speaker
Biography:

Muhammad Hasan Hameed has completed his BDS from Dow University of Health Sciences, Karachi, Pakistan. He is currently pursuing Fellowship in Operative Dentistry from Aga Khan University in Karachi, Pakistan. He has published more than 5 papers in reputed journals.
 

Abstract:

Background & Aims: Fixed implant-supported restorations are considered as the standard treatment for replacement of missing teeth. These can be either screw or cement retained. The success or failure of implant restorations depend upon amount of marginal bone loss (MBL). The present study is to determine the MBL around cement and screw-retained implant prosthesis and to determine various predictors of the MBL. 
 
Materials & Methods: A retrospective charts review was conducted at the dental clinics, Aga Khan University Hospital, Karachi from February 2017 to June 2017 in which 104 implants restorations were evaluated using peri-apical radiographs. MBL was calculated at baseline and at 12 months and the difference was recorded on a proforma. SPSS version 21.0 was used for statistical analysis. Descriptive statistics was computed. Independent sample t test was used to determine the difference in the MBL between the two groups (cement-retained vs. screw-retained) crowns and fixed partial dentures. Generalized estimation equation analysis (GEE) was applied to determine the predictors of MBL. Level of significance was kept at ≤0.05.
 
Results: There were 104 implant restorations belonging to 41 patients. There was no difference of the MBL around screw retained versus cement retained crowns. However, the distal surface of screw retained fixed partial dentures showed significantly greater MBL (p-value=0.028). Age, gender, medical status and bone grafting were found to be significant predictors of MBL. 
 
Conclusions: There was no difference in MBL between screw and cement retained prosthesis except on the distal surfaces of screw retained fixed partial dentures. Elderly diabetic males of age >65 years along with bone grafting turned out to be strong predictors of MBL.

Abstract:

A medical error is a preventable adverse effect of care, whether or not it is evident or harmful to the patient’s. This might include an inaccurate or incomplete diagnosis or treatment of a disease, injury, syndrome behavior, infection, or other ailment. Medical errors can occur anywhere in the health care system: In hospitals, clinics, surgery centers, doctors' offices, nursing homes, pharmacies, and patients' homes. Errors can involve medicines, surgery, diagnosis, equipment, or lab reports. These tips tell what you can do to get safer care. Medical errors leading to adverse events can occur in dentistry. The literature indicates that such errors broadly include: errors related to the prescription of medication, errors based on neglecting current scientific evidence regarding treatment, errors occurring during treatment or associated with improper maintenance of equipment, errors based on failure to properly maintain patient records, errors arising from the failure to acquire informed consent, the failure to establish and maintain appropriate infection control measures, the failure to properly diagnose, the failure to prevent accidents or complications associated with care or to pursue appropriate follow-up care when they occur, and the failure to follow authoritative dictates reflecting current standard of care or practice rules or regulations established by individual state laws. This presentation reviews the most common medical errors likely to occur in the practice of dentistry; outlines the recommendations by ADA for prevention of medical error and describe how to develop a root cause analysis and action plan to prevent further medical error.

Title: Photo-crosslinkable membrane for guided periodontal tissue regeneration
Speaker
Biography:

Pauline Marie Chichiricco obtained the Degree of Doctor in Pharmacy at Sapienza University in Rome, Italy. She is in her ultimate year PhD in a European program (Nanofar) between the Regenerative Medicine and Skeleton laboratory in Nantes, under the supervision of Professor Pierre Weiss and Doctor Xavier Struillou, and the Center for Education and Research on Macromolecules (CERM) at Liège University under the supervision of Professor Christine Jerome. Her research interest lies in biomaterials.
 

Abstract:

Periodontitis is an inflammatory disease resulting from the presence of oral bacteria biofi lm in periodontal tissue, which destroys the tooth-supporting attachment apparatus. Untreated inflammation can spread to all periodontal tissue and lead, ultimately, to tooth loss. Guided tissue regeneration (GTR) is a technique based on a barrier membrane designed to prevent colonization of the wound space by gingival cells. Indeed, these cells, with a faster migration and proliferation rate compared to those of bone and periodontal ligament ones, could interfere with the regeneration process. We developed a photo-crosslinkable formulation composed on methacrylated carboxymethyl Chitosan (MA-CMCS) and silanized hydroxypropylmethyl cellulose (Si-HPMC), that can be applied in situ and cured with a visible light lamp (λ 420-480 nm), already used in dentistry. Photocuring, in fact, appears the more appropriate technique for this application for its both shape and curing time control. We assessed the chemical and physico-chemical profile of this material, showing a quick time to obtain a solid membrane. To evaluate the degradation, the crosslinked material was soaked in highly concentrated lysozyme buffer at 37°C. Si-HMPC/ MA-CMCS material revealed a degradation profile between the two crosslinked biomaterials of reference. The in vitro biocompatibility was demonstrated by Neutral red assay using murine fibroblast (L929). Moreover, we studied the barrier eff ect of using primary cells, human gingival fi broblasts, observing the cells by confocal microscopy. No cells invasion was observed in Si-HMPC/MA-CMCS material. In addition, we set up an ex vivo experiment culturing human gingival explants in  presence of our biomaterial and using pullulan porous material as a negative control. After culture, the samples were stained with hematoxylin, eosin Y and safranin (HES). The histological sections revealed that the biomaterial exhibited the barrier eff ect in contact with soft  tissue. In the next future, in vivo experiment will be performed to further characterize the material for periodontal regeneration.

Title: Successful conservative management of oral lesions by decompression or marsupialization procedure: A case series
Speaker
Biography:

Akram Belmehdi is a Dental Doctor and a Specialist in the Department of Oral Surgery, Faculty of Dentistry, Mohamed V University, Rabat, Morocco. He is the Member of the Research Committee of Oral Biology and Pathology at the same university. He has published 6 papers in reputed journals and has been serving as a Reviewer of Journal of Medical and Surgical Research. He has participated in more than 30 oral presentations and posters in national and international dental and medical conferences.
 

Abstract:

Introduction: Several treatments have been described for the management of oral cysts, although none has been accepted globally. Nowadays, decompression, marsupialization, enucleation and resection of lesions are accepted as valid. The benefits of marsupialization and decompression include the gradually decreasing of the cystic cavity; preserving the adjacent oral tissues, maintaining pulp vitality, avoiding dental extractions, preventing iatrogenic damage to adjacent noble structures, avoiding mandibular fractures and reducing the risk of recurrence. In all cases, a second surgery is needed to eliminate totally the cystic lesion after decompression. Decompression and marsupialization are procedures that require patient’s commitment. They need several control appointments and constant hygiene with repeated irrigation, gauze soaked in iodine of the cystic cavity.
 
Aim: The aim of this work is to evaluate the effectiveness of the decompression and marsupialization as the primary treatment of the cystic lesions of the jaws and oral mucosa and their reduction rates involving different factors.
 
Materials & Methodology: A total of 12 patients with cystic lesion of the jaw and mucus-containing cystic lesion of the minor salivary gland were treated with decompression and marsupialization followed or not by enucleation. Pre- and postdecompression clinical features and panoramic radiographs were analyzed.
 
Conclusions/Clinical significance: Decompression and marsupialization proved to be simple, low cost, relatively noninvasive, painless, and low recurrence techniques to treat oral cystic lesions. All patients treated with decompression were reported to have shown a reduction in lesion size and higher sensitivity with a larger lesion size. There was no diff erence in the eff ect of decompression based on age, and only one patient experienced recurrence of the cyst.

Abstract:

Cigarettes are not the only form of tobacco smoked; in fact, waterpipe has been used for smoking tobacco for centuries. The name Waterpipe tobacco smoking (WTS) is used for the last 2 decades in the English language scientifi c literature to refer to any variety of instruments that involves tobacco smoke passing through water before inhalation. The use of water pipe is increasing daily, in all age and sex groups. There is a dire need to study and document health eff ects of water pipe smoking in general and specifi cally on the oral cavity as it has not been done anywhere else in the world till date. Since the oral mucosa is exposed to the smoke and its toxins from WTS directly, it will defi nitely help in studying the eff ects on it at a cellular and genetic level. The general public perception is that WTS is harmless. The waterpipe used just as other forms of tobacco use can be regulated if there is more awareness of its health eff ects. We collected socio-demographical, behavioral data pertaining to WTS and cigarette smoking in the region and studied their toxicological eff ects on the oral mucosa.

Abstract:

Splinting is a common treatment approach in dental practice to obtain stability and eliminate mobility. It has also been shown that splinting can decrease pain and discomfort during biting and chewing. In addition, splinting of the mobile tooth is recommended before regenerative periodontal treatment to obtain maximum benefits from the treatment. It was our experience that SRP instrumentation was made easier by the splinting due to the prevention of tooth mobility. As another benefit, the patient was no longer complaining about chewing or biting after splinting. With the aid of pink-splinting clinicians will enhance the esthetic results after periodontal treatment in patients with periodontal disease. In addition, they will also manage the papilla loss and its effects in patients. This technique may be life-saving in patients with aggressive periodontitis.

Abstract:

New technology is now available to healthcare providers to aid in the visualization of oral lesions. Fortunately, this technology can lead to earlier cancer detection and improved prognosis. This conference workshop addresses the following: familiarized attendees with autofluorescence technology, demonstrate how to use these instruments, explain the differences in the available devices, show how autofluorescence varies with the area of the mouth, explain how to recognize mucosal changes and distinguish oral cancer from entities such as amalgam tattoo, bacteria, varicosities, physiologic pigmentation, and inflammation, help attendees develop a one minute oral examination protocol utilizing this new technology immediately upon returning to their office/clinic.
