Comparative evaluation of novamin probiotic and fluoride containing dentifrice on the incidence of white spot lesions during orthodontic treatment using laser fluorescence a prospective randomized controlled clinical trial

Abstract

9 OF 75 newlineABSTRACT newlineBackground newlineDemineralization is an inevitable side effect of fixed orthodontic treatment, newlineespecially when it is associated with poor oral hygiene. Orthodontic appliances are newlineassociated with particular oral hygiene challenges, since they act as plaque traps newlineand make satisfactory mechanical oral hygiene difficult. The formation of WSLs newlineafter completion of orthodontic treatment is a discouragement to the orthodontist newlineas well as the patient. newlineAim newlineThe study is aimed to do a comparative evaluation of probiotics, novamin newlinecontaining dentifrices with fluoride dentifrice for the incidence of white spot lesions newlinein subjects undergoing treatment with fixed appliances. newlineMaterials and Methods newlineIn this prospective double-blinded randomized clinical trial a total of 93 newlinesubjects who fulfilled the selection criteria were included. 31 subjects were newlineallocated randomly into three groups and with a drop out of 8 subjects due to newlinerelocation and discontinued intervention, a total of 85 subjects were evaluated for newlineenamel demineralisation at T1. DD scores were noted at both T0 - just before newline10 OF 75 newlinebonding and T1 - 6 months into treatment. All statistical analyses were done using newlineIBM SPSS Statistics software version 20.0 for Windows. Descriptive statistics were newlineperformed. One-way ANOVA analysis was carried out to evaluate the intergroup newlinedifference in mean DD scores. Intraclass correlation coefficient analysis was done newlineto analyze intraobserver reliability. newlineResults newlineSignificant intergroup differences in the mean DD scores at T1 were noted newlinein all teeth evaluated except for lower right central incisor ( p valuegt0.05). The newlineteeth with highest incidence of WSLs was the lower right canine in group C (12.9%) newlineand the least incidence of WSL was noted on lower left lateral incisor in group B newline(0.92%). An overall higher incidence of WSLs was noted in group C (46.29%) as newlinecompared to group A (20.37%) and group B (43.38%). Males had a higher newlineprevalence of WSLs in group A (75.16%), group B (30.33%) and group C newline(14.28
