Abstract

The combination of proper instrumentation, irrigation, and obturation of the root canal is essential for effective root canal therapy. The most important determinant in the healing of the periapical tissues is irrigation of the root canal, which is one of the three basic stages of root canal therapy. As a result, the main aim of endodontic therapy would be to improve root canal disinfection and avoid reinfection. Various irrigants and relationships between irrigants are explored in this analysis of the literature.   Keywords : NaOCl, Herbal.

Abstract

Preserving the vitality of pulp can never be overemphasized. Conventionally, pulp exposures were root canal treated but it results in loss of vitality of pulp. Vital pulp therapy maintains tooth vitality, functionality and to render tooth asymptomatic. Pulpotomy using Calcium silicate based cements could be a good alternative for RCT for management of symptomatic mature permanent teeth with carious pulp exposure, however large scale clinical trials are highly encouraged to confirm this hypothesis.

Abstract

Introduction : Root canal treatment is a type of endodontic therapy used to perform for the elimination of the micro-organisms by standardized mechanical instrumentation and adequate cleaning and shaping of the infected root canal. The readily available root canal irrigants which are used in endodontic therapy have shown somewhat toxic and harmful side effects when used at certain concentration, some of the endodontic irrigants have shown species specific resistance to a particular microbial load that’s why there is a need to discover newer irrigants which are non toxic, effective and can be used safe to use. Aim: In vitro evaluation and comparision of the antimicrobial efficacy of 0.1% octenidine dihydrochloride (OCT), of 2% chlorhexidene (CHX) and 2% chitosan as root canal irrigant against E. faecalis within the dentinal tubules at 200m and 400mm depth. Materials and Methods: Seventy two freshly extracted mandibular molars were decoronated and the mesial root specimen was standardized till working length. E.faecalis (strain MTCC 439) was grown on brain heart infusion sheep blood agar plate until seven days and the decoronated root specimens collected were divided into four groups (n=18) based on irrigation protocol: Group 1 – 2% chlorhexidene (CHX), Group 2 - 0.1% octenidine dihydrochloride (OCT), Group 3- 2% chitosan and Group 4 – normal saline. Each specimen was irrigated with particular irrigant till 3 minutes. Dentin shavings were obtained from root specimens using diamond disc and these dental chips were used to calculate the colony forming unit at 200m and 400mm depth. The data obtained after the experiment was statistically analyzed. Results: Non significant difference has been shown by group 1when compared with group 2 while significant difference has been shown by group 3 when compared with group 1 and group 2 by taking into account that group 4 is taken as control group. Significant difference was found when all the groups 1-4 were compared at 200 and 400 mm depth. Conclusion: It was observed and evaluated that antimicrobial efficacy of 2% chitosan against e. faecalis was found to be higher as compred to 2% chlorhexidene (CHX) and 0.1% octenidine dihydrochloride (OCT) both at 200m and 400mm depth.
