Dental caries and trauma are two main causes for pulpal inflammation or infection for which root canal treatment is carried out. These conditions cause moderate to severe loss of tooth structure which is restored using post endodontic restorations like post and cores. The post provides intracanal retention of the core and crown restoration and distributes functional loading over a large area to achieve favourable stress distribution in endodontically treated teeth. The two commonly used post and core systems for posterior teeth includes prefabricated metal post and custom made post. The aim of this study is to evaluate various post endodontic restorations practiced for maxillary and mandibular molars.
For this study, data of all post endodontically treated maxillary and mandibular molars from June2019 to March2020 was extracted from the patient management software of saveetha dental college,Chennai. The retrieved data was evaluated by 2 reviewers. Parameters like age,gender and tooth number were noted and correlation between these parameters was studied using chi square tests.
The study showed no statistically significant difference in the use of prefabricated metal post and custom made posts in maxillary and mandibular molars[p value > 0.05(chi square test)]
Prefabricated metal posts were seen more commonly placed in the age group of 18-30 years with equal distribution among the two genders while custom made posts were commonly placed in the age group of 31- 40 years and was commonly distributed among females.
