Impact of Bruxism in the Outcome of Subgingival Instrumentation for the Management of Stage 2 and Stage 3 Periodontitis.

AIM : To study the impact of bruxism in the outcome of subgingival instrumentation for the management of Stage 2 and Stage 3 periodontitis. OBJECTIVES: To assess the association of bruxism with periodontitis. STUDY DESIGN: An interventional study will be conducted in the Department of Periodontics and Oral implantology PGIDS, Rohtak. STUDY SETTING: Hospital based study- patients diagnosed with Stage 2 and Stage 3 Periodontitis associated with bruxism will be recruited in study from OPD. TIME FRAME: 12-14 months Sociodemographic variables: Sociodemographic data comprises of : 1. Gender 2. Age 3. Educational level, 4. Occupation status (student, employed, unemployed or retired), 5 Marital status (single, married, divorced or widowed), 6\. Average family monthly income. POPULATION: Systemically healthy patients with generalized periodontitis : stage 2 and stage 3 of age group of 30-50 years will be recruited in the study from OPD of Periodontology. Recruitment of the patients for the study will be based on eligibility criteria after obtaining informed and written consent. SAMPLE SIZE: Sample size determination was done by using G power software. Taking alpha= 0.5 and power of 90% , minimum 23 patients in each group are required to detect a clinically relevant change of 1mm in clinical attachment level with standard deviation of 1mm between both the groups. Hence a total of 58 patients (29 in each group) will be included in the study expecting a 25% drop out rate. METHOD: Patients fulfilling the eligibility criteria will be enrolled in the study after obtaining the informed consent. Periodontal parameters will be assessed which include clinical attachment level (CAL), periodontal pocket depth (PPD), bleeding on probing (BOP), Gingival index (GI),Tooth mobility.
