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. Most patients returned after two years with a complaint of discoloration.
Clinical significance: The study is relevant clinically as it deals with the techniques used by general dental practitioners while performing composite resin restorations. The study highlights clinical practices which are in line with evidence-based dentistry and also with techniques adapted by dentists which are obsolete and require an update.
