AIM: To assess the effectiveness of a customized oral health program to improve the Oral Health Related Quality of Life among Gypsy/Narikuravars.

RESEARCH QUESTION: Is there a difference in the Oral Health Related Quality of Life among gypsies before and after giving a customized oral health program?

STUDY POPULATION:  Narikuravars/Gypsy aged between 18-60 years population.

SAMPLING PROCEDURE:  The sampling method by which the study subjects would be selected is Cluster Sampling.

SAMPLE SIZE:  The sample size was calculated using G power software version 3.1. The calculation was based on the mean DMFT values (5.30 ± 3.160) among narikuravars from a previous study conducted by Mahalakshmi kumaraguru et al (2023). With 95% power and alpha error 5%, the sample size was calculated to be 132. Anticipating a 10% loss to follow up, the sample size is calculated as 140. Thus, the total sample size N=140.

METHODOLOGY: The study subjects will be selected using cluster sampling based on the inclusion criteria and exclusion criteria. At baseline, demographic data , Oral Health Related Quality of Life using Oral Health Impact Profile (OHIP 14) questionnaire  and GATS questionnaire will be collected by interview method. Debris score and calculus score will be assessed using Oral Hygiene Index – Simplified by Greene & Vermillion in 1964.  To assess the dentition status, periodontal status and loss of attachment using WHO oral health assessment form for adults, 2013.

INTERVENTION:  Study participants will receive a toothbrush and toothpaste, along with education on proper oral hygiene practices, including using a pea-sized amount of toothpaste and the modified Bass toothbrushing technique demonstrated on models. They will also learn about other aids like tongue cleaners, flossing, and rinsing after meals. Instructions will cover toothbrush storage, replacement every three months, regular oral prophylaxis (every 6–12 months), and addressing oral health misconceptions. Awareness about tobacco-related habits will be included. A standardized oral health education program will be developed for the gypsy population. Participants will undergo dental screening, followed by necessary treatments such as scaling, restorations, and extractions.
