RADIOGRAPHIC EVALUATION OF REMAINING DENTIN THICKNESS AFTER POST SPACE PREPARATION IN PATIENTS UNDERGOING CUSTOM CAST POST- A RETROSPECTIVE STUDY

Abstract

The aim of the present study is to radiographically evaluate the remaining dentin thickness after post space preparation in patients undergoing custom cast post. 86000 patients’ records from June 2019 to March 2020 were reviewed for this study and the data of 57 patients from pertaining to our study was collected and analyzed. It is an Institutional based Retrospective study. Data were categorized based on post space preparation type for all the teeth and tabulated in excel sheets based on age, gender, type of post space preparation, and the teeth. The data were statistically analyzed with Chi square test using SPSS software. There was no statistically significant association between the variables age, teeth, and type of preparation (p >0.05). However, the analysis showed that proportionist theory was followed maximum compared to other theories in the age groups and also a maximum number of cast posts was done in maxillary central incisor compared to maxillary lateral incisor and canine. The major advantages of a custom cast post are its custom fit to the root configuration, strength, adaptability to oval shaped canals and change of angulation of crown. The postgraduate students opted for the proportionist theory with the intention of saving the tooth structure and preserving the remaining dentin thickness to enhance the retention of the post.
