EFFECTIVENESS OF CHLORHEXIDINE AS A CAVITY DISINFECTANT IN ATRAUMATIC RESTORATIVE TREATMENT IN PRIMARY TEETH (RANDOMIZED CONTROLLED CLINICAL TRIAL)

Introduction: Since the removal of caries in Atraumatic restorative treatment (ART) is performed with hand excavation, its survival would increase if more bacteria could be inhibited under restoration. The use antibacterial agents such as Chlorhexidine gluconate (CHX) was found to hinder growth restorations, reducing risk recurrent caries. Objective: Evaluate effectiveness CHX a cavity disinfectant, on residual cariogenic bacteria, ART restorations. Materials and methods: procedures were whole sample (N=40), identical protocols except for agent used. Bacteriological samples from center cultivated Mutans streptococci (MS), Lactobacilli (LB) total viable count (TVC). applied onto floor group I (N=20) conventional without disinfectant II (N=20). After 14 days, restorations removed second dentin bacteriologic assessment outcome. Results: Group showed 22.17, 8.25, 6.88 mean percent reduction MS, LB, TVC, respectively whereas 12.67, 6.87, 6.11 respectively. MS LB significantly higher compared II. Moreover, TVC than II; however, it not statistically significant. Conclusion: disinfection superior inhibiting restoration using glass ionomer cement (GIC) alone.
