Efficacy of Resin-Modified Glass Ionomer Cement Varnish and Sodium Fluoride Varnish in The Prevention of White Spot Lesions During Fixed Orthodontic Treatment- A Split Mouth Study

Abstract

Objective: Evaluating efficacy of Resin-Modified Glass Ionomer Varnish and Sodium Fluoride Varnish in prevention of White Spot Lesions (WSLs) during early fixed orthodontic treatment; comparing the incidence of white spot lesions in control teeth and experiment teeth. Methodology: Design: A Cross-sectional analytical split mouth study. Setting: Orthodontic Department of Sinhgad Dental College and Hospital. Participants: A sample size of 288 maxillary and mandibular anterior teeth (24 participants) with newly placed orthodontic brackets, allocated randomly into 4 subgroups, 2 experimental and 2 control. Interventions: For each experimental quadrant in each patient, respective varnishes were applied on the labial surfaces of anterior teeth. WSLs were recorded before and after 3 months by direct visual inspection following International Caries Detection Assessment System II Criteria. Results: There was significant difference between pre and post recordings of both the varnishes (p<0.05). The control groups showed higher incidence of (WSLs) as compared to the experimental groups (p<0.05). Conclusion: The result obtained from the study suggested that both Sodium Fluoride Varnish (Embrace) and RMGI Varnish (Clinpro XT) will help to prevent WSLs in orthodontic treatments.
