Abstract

Background and objectives: The main causative factors for maximum periodontal diseases are dental plaque and oral biofilms. This study was done to check the impact of quantitative light-induced fluorescence-digital (QLF-D) as a motivational tool for plaque control among children from various schools situated in Dehradun district along with education using audiovisual aids.

Materials and methods: A total sample of 800 school-going children including both males and females aged 6 to 12 years from various schools situated in Dehradun district of Uttarakhand were surveyed. A pro forma was prepared and the demographics of the students were noted. All the students were first examined for the Oral Hygiene Index-Simplified (OHI-S) and then the random division was done into two groups, group A (Q-scan) and group B (basic diagnostic aids) for examination of plaque index.

Results: The results of the study revealed that good OHI-S scores increased significantly from 1st visit to 3rd visit. The plaque scores for the control group, when examined with basic diagnostic aids of all three visits, were significantly good which increased subsequently from 1st visit to 3rd visit. Good plaque index score increased significantly for the test group from 1st to 3rd visit when examined with QLF-D.

Conclusion: We found in our study that QLF technology is of paramount importance in epidemiological surveys and plays a pivotal role in evaluating masses in maintaining oral health care.
