Assessment of Salivary Mutans Streptococci Counts to Atraumatic Restorative Treatment Among Children: A Randomised Controlled Trial.

Abstract

Introduction Besides the survival rate of restorations, the effect of atraumatic restorative treatment (ART) on bacterial count is also important. After ART restoration, the bacterial count drops due to the fluoride's antibacterial activity and hence it can decrease the chances of further decay. The present studyassessed salivary mutans streptococci counts for six months of evaluations subsequent to ARTamong 12-15-year-old children attending schools in Piparia village, Vadodara district. Methods ART was performed on 32 children and followed up after six months to evaluate the success rate of ART. Saliva collection and microbial analysis were performed five times from every participant, before ART restoration placement, seven days, 30 days (one month), 90 days (three months) and 180 days (six months) post-restoration. Results At baseline, the mean colony forming units (CFU) was 48.30 ± 46.58, which reduced to 32.64 ± 30.40 at one week, which showed a 32% reduction in colony counts. This further reduced to 18.60 ± 20.81 at one month, marking a further 43% reduction in colony counts. This again reduced to 13.63 ± 18.04 at three months, which showed a 27% reduction in colony counts. CFU came to 16.23 ± 23.34 at six months, which showed a 19% increase in colony counts. Comparison of baseline mean CFU (48.30 ± 46.58) to six months mean CFU of streptococcus mutans (SM) (16.23 ± 23.34) showed a 66% reduction in colony counts. A statistically significant difference was found between numerous intervals of time of CFU of streptococcus mutans. Conclusion The findings reveal that ART is a clinical treatment that can be used to treat caries in young children, and it helped significantly reduce Streptococcus Mutans levels in saliva.
