Comparative Evaluation of White Spot Lesion incidence between NovaMin, Probiotic, And Fluoride containing Dentifrices during Orthodontic treatment Using Laser Fluorescence - A Prospective Randomized Controlled Clinical Trial

Background Orthodontic appliances act as plaque traps leading to the demineralization of teeth.Aim The purpose of the study was to compare Probiotics, NovaMin, and fluoride-containing dentifrices in terms of the incidence of white spot lesions in subjects undergoing treatment with fixed appliances using laser fluorescence.Materials and Methods In this prospective double-blinded randomized clinical trial, a total of 93 subjects were equally assigned to one of the three groups (Group A – Probiotic containing dentifrice, Group B – NovaMin containing dentifrice and group C – Fluoride containing dentifrice). Diagnodent scores were noted at T0 (just before bonding) and T1 (6 months into treatment). Statistical analyses were performed with Windows version 20.0 of IBM SPSS Statistics.Results Significant intergroup differences were noted in all teeth except for the lower right central incisor . Teeth with the highest incidence of WSLs were the lower right canine in group C (12.9%), and the least incidence of WSL was noted in the lower left lateral incisor (group B-0.92%). An overall higher incidence of WSLs was noted in group C (46.37%) as compared to group A (20.37%) and group B (43.05%). Males had a higher incidence of WSLs in all the three groups. The incidence of WSLs was highest in the age group of 26–35 years in all three groups. Conclusion WSL incidence was least in subjects on Probiotics-containing dentifrice. Adult males had a high incidence of WSLs. The lower right canine had the highest overall incidence of WSLs in all groups.
