Objectives Successful endodontic therapy is based on the reduction of infecting bacteria by cleaning, shaping, and disinfecting of the root canal system, thus the use of intracanal dressing is necessary for optimal success of root canal treatment. This study was designed to evaluate the effect of chitosan and propolis as intracanal medicaments against Enterococcus faecalis compared to calcium hydroxide in primary root canals. Material and Methods Ninety‐six extracted primary second molars were collected. Teeth preparation was completed to size 30 K‐file. They were randomly divided into four groups; (A): chitosan, (B): propolis, (C): calcium hydroxide, and (D): control group (saline). The tooth specimens were inoculated with E. faecalis . Then, tested materials were applied for all groups in accordance to the groups each tooth belonged to. Following this, the bacterial colonies were counted after 24 h, 72 h, and 1 week of applying dressing materials and incubation. Finally, one–way analysis of variance and Fisher's least significant difference tests were used for statistical comparisons between the groups at a significance level of .05. Results No statistically significant difference was found between groups A, B, and C for both 24 h and a week ( p ≥ .05). Yet, a statistical difference between groups A, B, C, and D after 72 h and 1 week were seen ( p ≤ .05). Conclusions Chitosan and propolis medicaments were as effective as calcium hydroxide against E. faecalis in primary root canal treatment and might be considered as an alternative dressing material between treatment sessions.
Objective: To evaluate the efficacy of a new pepsin enzyme-based gel compared with Carisolv as a CMCR agent. Clinical and radiographical evaluations of recurrent caries were made 3 and 6 months after treatment. Material and Methods: A split-mouth designed randomized controlled clinical study was carried out on 40 primary anterior teeth of children aged between 4-7 years. Pepsin enzyme-based gel and Carisolv solution were applied to carious lesions until complete removal of caries. The efficacy of both agents was evaluated by the number of application times to remove all caries. Recurrent caries were evaluated clinically and radiographically after 3 and 6 months of treatment. Results: Results showed no statistically significant differences in the efficacy of caries removal by the number of application times (P = 0.919). Concerning recurrent caries, clinical and radiographical evaluation after three and six months showed no statistically significant differences between the two groups (P = 0.574, P = 0.547, respectively). Conclusion: Pepsin enzyme-based gel can be considered similar to Carisolv gel regarding its efficacy as a CMCR agent for small carious lesions on primary anterior teeth in children aged 4-7 years old.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
