Arup Ratan Choudhury is an exception achiever, specialist dental surgeon, humanist, media compare as well as a noted singer of Bangladesh. Who has devoted his life to the service of mankind, was born in 1952. He has shown a remarkable contribution in management of medically compromised patients and scientific research during the last 25 years. He has been Head & Senior Consultant of Birdem Hospital since November 1988. At present he is the Hon senior Consultant of Birdem Hospital & also the professor of Dentistry Ibrahim Medical College. He became the Member of the National Drug Control Board and National Task force for Tobacco Control Board since 2001. He presented 33 scientific papers in different international scientific seminars. He received National award of Bangladesh “EKUSHEY PODOK” for the outstanding contribution in social work in 2015.
Many systemic diseases are reflected in the oral mucosa, maxilla and mandible. Mucosal changes may include ulceration or mucosal bleeding. Immunodeficiency can lead to opportunistic diseases such as infection and neoplasia. Bone disease can affect the maxilla and mandible. Systemic disease can cause dental and periodontal changes. Drugs prescribed for a systemic disease can affect oral tissue.
Oral conditions have an impact on overall health and disease. Bacteria from the mouth can cause infection in other parts of the body when the immune system has been compromised by disease or medical treatments (e.g., infective endocarditis). Systemic conditions and their treatment are also known to impact on oral health (e.g., reduced saliva flow, altered balance of oral microorganisms). Oral manifestations - Commonly occurs in mucosal surface of buccal mucosa, vestibules, tongue, lips, floor of the mouth, palate. Appears weeks or months before the skin lesions. Lesions are bilaterally symmetrical.
Oral health is essential to general health and well-being at every stage of life. A healthy mouth enables not only nutrition of the physical body, but also enhances social interaction and promotes self-esteem and feelings of well-being. The mouth serves as a “window” to the rest of the body, providing signals of general health disorders. For example, mouth lesions may be the first signs of HIV infection, aphthous ulcers are occasionally a manifestation of Coeliac disease or Crohn’s disease, pale and bleeding gums can be a marker for blood disorders, bone loss in the lower jaw can be an early indicator of skeletal osteoporosis, and changes in tooth appearance can indicate bulimia or anorexia. The presence of many compounds (e.g., alcohol, nicotine, opiates, drugs, hormones, environmental toxins, antibodies) in the body can also be detected in the saliva. Oral disease is the most widespread chronic disease, despite being highly preventable. It has become increasingly clear that the oral cavity can act as the site of origin for dissemination of pathogenic organisms to distant body sites, especially in immunocompromised hosts such as patients suffering from malignancies, diabetes, or rheumatoid arthritis or having corticosteroid or other immunosuppressive treatment. A number of epidemiological studies have suggested that oral infection, especially marginal and apical periodontitis may be a risk factor for systemic diseases. The oral cavity contains some of the most varied and vast flora in the entire human body and is the main entrance for 2 systems vital to human function and physiology, the gastrointestinal and respiratory systems. Several diseases involve these 2 systems and manifest in the oral cavity. In addition, a specific pathologic condition, such as periodontitis (i.e., inflammation of the periodontal attachment of the teeth and the alveolar bone), may be present in the oral cavity. These specific conditions in the oral cavity may create foci of infection that can affect many other vital systems, such as the cardiovascular and renal systems. Foci of infection in the oral cavity arising from chronic periodontitis or chronic periapical abscesses (i.e., inflammation and abscess of the tissue attached to the apex of the root) may lead to subacute bacterial endocarditis (BE) and glomerulonephritis (GN).
That the mouth and body are integral to each other underscores the importance of the integration of oral health into holistic general health policies and of the adoption of a collaborative “Common Risk Factor Approach” for oral health promotion.

Yeditepe University, Turkey
Omid Panahi has completed his graduation in the field of Doctor of Dental Medicine ( DMD) at Centro Escolar University in 2013. He has completed his MSc in Oral and Maxillofacial Surgery at Yeditepe University, Istanbul, Turkey. He has published more than 40 papers in reputed journals and has been serving as an Editorial Board Member of ISI journals.
In the last few decades, nanotechnology has became prominent in medical sciences, especially in dentistry, including the treatment and prevention of oral and dental disease using nanosciences. Therefore an understanding of nanotechnology is an essential to further understanding how these materials can be used in dentistry. Further, various modern nanotechnology products and new therapies are on the way. This study discusses the latest advances of nanotechnology in dentistry; including nano-based oral and dental technologies being the major improvements in restorative dentistry (nano-composites, nano-resin modified GIC, nano-GIC, mineral solutions); in Prosthodontics (nano-hybrid composites); in Endodontics (sealers); in Periodontics (Grafts, nano-materials for tissue regeneration); in Oral Implantology (nanonite implant); and in Orthodontics ( nanorobots, archwires). With the development of nanotechnology and the use of nanomaterials in dentistry, it will eventually improve the quality of lifes of millions of persons by improving examinations and medical and dental treatments with new technologies.
