Association Between Number Of Walls Present And The Type Of Post Used In Maxillary Premolars - An Institution Based Retrospective Study

Abstract

Most Endodontically Treated Teeth Require Post And Core For Restoring The Tooth Back To Its Form And Function. Selection Of An Ideal Post And Core System Poses A Challenge To The Clinicians As It Is Influenced By Several Factors Including Tooth Anatomy, Tooth Position, Remaining Tooth Structure, Root Length And Configuration, Forces Acting On Tooth, Esthetics And Patient’s Affordability. This Study Was Undertaken To Evaluate The Association Of Number Of Walls Remaining And The Type Of Post Selected In Endodontically Treated Maxillary Premolars. This Was A Retrospective Analysis Done In A University Setup. The Case Records Of Patients Who Underwent Root Canal Treatment In Maxillary Premolars And Required Restoration With Post And Core In The Period Between June 2019 To April 2020 Were Taken And Evaluated. All The Data Was Compiled And Tabulated In Microsoft Excel And Exported To Ibm Spss Version 20. Descriptive Analysis Done To Evaluate The Frequency Percentage And Chi Square Test Done To Find The Association Between The Type Of Posts And The Number Of Remaining Walls. The Level Of Significance Was Set At 0.05. No Significant Association Was Found Between The Type Of Post Used In Maxillary First And Second Premolars (P Value- 0.836; Chi Square Test). There Was A Significant Association Between The Type Of Post Used And The Number Of Walls Present (P Value- 0.013; Fisher’s Exact Test). Within The Limitations Of This Study It Was Found That Prefabricated Metal Post Was Preferred Over Prefabricated Fiber Posts In The Restoration Of Maxillary Premolars Irrespective Of Number Of Walls Remaining There Was No Significant Difference In Post Selection For A Maxillary 1^st & 2^nd Premolars.
