Objective: The objective of this study was to evaluate clinically and radiographically the chitosan-zinc oxide eugenol mix as pulp capping material in primary teeth. Materials & Methods: The study was performed on 36 primary molars of patients aged from 4-8 years that were indicated for pulpotomy. The teeth were divided randomly into 2 main equal groups. Each group formed of 18 primary molars. Group A: 18 children teeth in which zinc oxide and eugenol (ZO/E) was used as pulp capping material after formocresol (FC) application. Group B: 18 children teeth in which Chitosan-ZO/E mix was used as pulp capping material. The teeth were assessed clinically and radiographically at 4 different intervals (preoperative, 24 hours, 6 weeks and 3 months postoperative), using standard clinical and radiographic criteria. Results: It was found that chitosan-ZO/E mix offers good clinical and radiographic results when compared with ZO/E after application of FC but with no statistically significant differences.
Conclusion:ZO/E after application of FC (group A) showed (83.33%) success rate, while the Chitosan-ZO/E mix (group B) showed a higher success rate (94.44%). Chitosan-ZO/E mix is a promising material as pulp capping material with a high success rate and showing competitive properties to ZO/E after FC application.
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.
