Periodontology is the branch of dental science that deals with the supporting structures of the teeth. The longevity of the dentition and the maintenance of its health depend upon proper periodontal management, involving routine dental check up and prophylaxis. Periodontal surgical treatment procedures such as flap surgeries and bone regenerative techniques using grafts and membranes are routinely carried out in the Department of Periodontics. Perioaesthetics is attained though various plastic procedures such as mucogingival surgeries, gingivoplasty, periodontal microsurgery etc. The surgical placement of implants is a comparatively new field that involves replacement of lost teeth with a bone integrating implant device. Recent advances in the field of molecular biology, genetic engineering and immunology are having a great impact in the diagnosis, treatment and prognosis of periodontal disease and more exciting avenues are expected to open in the field of periodontal research.
