Rationale- Periodontal disease is a dynamic inflammatory condition, that affects the periodontium and has a profound effect on the overall systemic health of the individual. Unfortunately, the symptoms of periodontal disease often go unnoticed by affected individuals and this contributes towards unpleasant and irreversible consequences such as tooth loss. Hence it is important to develop an easy, cost effective and widely acceptable method for the patients to assess their periodontal health.

Objectives- To translate, culturally adapt and validate the CDC/AAP questionnaire along with other relevant surveillance questions in the Hindi language according to the new case definitions of periodontal diseases.

Methods- The original 8-item CDC/AAP questionnaire as well as other selected periodontal disease surveillance questions will be translated into Hindi through forward translation, backward translation, and expert committee process to reach a consensus and produce a final version. The final version of the questionnaire will be administered to patients seeking care from out-patient department of department of Periodontics at PGIDS, Rohtak. Full-mouth periodontal examination, consisting of measurements of the probing pocket depth (PPD), full mouth bleeding score (FMBS) and clinical attachment level (CAL) at six sites per tooth using periodontal probe will be carried out for each participant.

Background- Periodontal disease, with its chronic systemic effects and poor influence on the quality of life of the patient, is global healthcare challenge. Hence there is a for timely diagnosis and treatment of the patients.

Expected outcomes- Response to self- reported questionnaire (individual questions as well as in combination) in Hindi speaking population and its ability to predict periodontal status will be evaluated. If found to be valid, this could serve as a vital tool for periodontal health screening for Hindi speaking population at the primary care level.
