Abstract

Aim: The aim of this cross-sectional study was to identify and analyze the attitudes and practices of general dental practitioners of Karachi, Pakistan while performing dental composite restorations. Material and methods: A self-applied questionnaire was furnished to 150 general dental practitioners. A total of 125 practitioners filled and returned the filled questionnaire. The questionnaire mainly enquired about the commercial brand of composite resin used, dispensing and curing methods, handling techniques, finishing/polishing practices, and discoloration complaints made by the patients (if any). The results were collected and analyzed statistically. Results: The response rate was 83% (n = 125). The results indicated that 80% (n = 100) of the respondents claimed that they use a single paste system and blue light for curing. The number of dentists who covered the lid of single paste composite after usage was 68% (n = 85), whereas 72% (n = 90) used transparent matrices after placement the final layer of the composite restoration. Majority of the practitioners preferred finishing discs 53% (n = 66), and 84% (n = 105) of the patients returned with the discoloration complaint after two years. Conclusion: Majority of the general dental practitioners in Karachi, Pakistan preferred single paste system, blue light for curing, and discs for finishing restorations.
