Choice of material for fixed dental prosthesis: a cross-sectional study.
Pak Oral Dental J Jan ;36(3):515-9.

The objective of this study was four fold; to find out the materials of choice for fixed dental prosthesis(FDP), role of luting agent in post operative sensitivity, to find out the trend of elective root canal therapy (RCT) among the clinicians prior to provision of FDP and to record the frequency of temporary crown placement by the clinicians. A cross-sectional study was performed in two dental Institutes; Armed Forces Institute of Dentistry (AFID) and Margalla Institute of Health Sciences (MIHS) of Rawalpindi City from 24thMay to 30th August 2016. Non-probability convenience sampling was done in this survey. Raosoft sample size calculator was employed to determine the sample size of 150 by keeping the level of confidence at 95%. The response rate was 87%. The collected data were analyzed and interpreted using SPSS version 21. For categorical variables frequency was calculated. Using Pearson’s chi-square test the level of association between designation of the clinicians and their preferred materials of choice for FDPs as well as frequency of temporary crowns provision was also calculated. Majority of the dentists preferred all ceramic (53%) for anterior FDP and ceramic fused to metal (61%) for posterior FDP. Among luting agents, Glass-ionomer cements (GIC) (77%) was the most popular luting agent and resin cements (40%) used by acid etch technique was labeled to be the most irritant luting agent leading to post-operative sensitivity. Elective RCT was performed by 49% clinicians only if the tooth was sensitive to percussion and 70% clinicians provided temporary crowns only in case of anterior and vital teeth. The study highlighted the materials commonly used by the dentists and the differences in the choices and practices of the dentists regarding prosthodontic treatment. It also pointed out some important factors such as an increase in frequency of temporization and careful justified decision of elective RCT by the dentists.
