Clinical and Radiographic Evaluation of 2.25% Sodium hypochlorite gel and Brix 3000 in caries removing of deciduous teeth.

Objective: Evaluation the efficacy of 2.25% sodium hypochlorite gel and Brix 3000 in caries removal of deciduous teeth. Subjects and methods: Thirty-six primary molars (class 1) with depth of caries not more than the coronal two thirds of dentine thickness. The children were aged 4-7 years and randomly divided into three equal groups based on the method of caries removal. The time of caries removal in each tooth was calculated using a stopwatch and the mean time of each method was obtained. The physical pain was also assessed by asking the children to choose the face that express their feeling using the Wong-Baker FACES analysis scale. The children were recalled for clinical and radiographic evaluation after 1and 6 months. Results: The conventional method showed the shortest time (2.82±0.477 min.) of caries removal followed by Brix 3000 (5.47±1.35min.) and 2.25% sodium hypochlorite gel (7.24±1.45 min.). Concerning pain sensation; the conventional method showed the highest grade of pain sensation with high significant differences from the two other chemomechanical methods. The results showed no significant difference between 2.25% sodium hypochlorite gel and Brix 3000. The clinical and radiographic evaluation showed that there was no significant difference after 1 and 6 months between all groups. The success rate among these groups showed that there was no significant difference between the success rates in all groups. Conclusion: 2.25% sodium hypochlorite gel and Brix 3000 are effective chemomechanical caries removing agents.
