Abstract:

Oral cancer awareness by the public is essential to addressing the need for routine screenings. Th e risk factors for oral cancer have expanded. Human Papilloma Virus (16 and 18) must now be included with the usual concerns of tobacco use and alcohol abuse. Th e gold standard for cancer diagnosis is the histopathological analysis of a suspected lesion. However, a lesion must fi rst be detected. Oral cancer screening is a pillar of comprehensive and periodic oral evaluations and early detection reduces the morbidity and mortality. Th e goal of early detection may be more easily achievable with the use of autofl uorescence technology. If a clinician can visualize a potentially harmful lesion easier, then this earlier detection may lead to improved prognosis. When oral tissue is exposed to a blue wavelength of light, the endogenous fl uorophores are excited to emit a green wavelength. With the appropriate fi lter, the healthcare provider can visualize the resulting autofl uorescence. Normal tissue appears varying shades of green and abnormal tissue typically appears dark. Since premalignant dysplasia may not be readily apparent to the naked eye, this technology can be useful in detection of oral mucosal abnormalities. However, it must be noted that vascular lesions, pigmented lesions, and amalgam tattoos have decreased fl uorescence. Diascopy, applying pressure to evaluate if the lesion blanches, can assist the clinician in determining whether a lesion is vascular/infl ammatory or nonvascular. Physiologic pigmentation and amalgam stain do not blanch. Th ere are several types of devices available. Th ese will be presented.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
