Evaluation of single crowns using USPHS criteria during cementation - A retrospective study

Abstract

The modern era is seeing an incline in dental health issues namely dental caries, missing teeth, etc. causing an increased use of prosthetics to replace the function of such teeth or provide esthetics. This has led to various studies in this field to improve the quality and lifespan of the crowns. An important aspect of this is to consider the cementation process and luting material used, which are crucial in determining the result. A retrospective study was done on patients reporting to Saveetha Dental College and Hospitals. A sample size of 1055 was obtained and data tabulated using the Excel sheet. SPSS software was used to analyze the data statistically. Chi-square test was done to evaluate the association between tooth type and cement used, USPHS scores for adaptation, colour match, marginal discoloration and surface roughness. The study revealed that GIC was the most common luting material used which was statistically significant and lower molars were the most involved sites for cementation. The most common USPHS score for adaptation, marginal discoloration and surface roughness for all types of tooth was Score 0. For color match, the most common USPHS score was Score 1.
