Abstract

Introduction: Today, composite resins are a suitable choice for tooth restoration, which in relation to posterior teeth, the most important limitations are marginal leakage, secondary decay, poor load bearing capacity, high wear and inability to restore contact. The durability of posterior restorations especially class II restorations is less compared to amalgam restorations. This has been affected by various factors such as polymerization shrinkage, thermal expansion coefficient and abrasion resistance that limits the durability of the posterior composite.

Methods: The present study was a cross-sectional descriptive study, which 68 final year dental students of School of Dentistry of Shahid Sadoughi University of Medical Sciences in Yazd City were selected by census and their attitude and awareness were studied using a valid and reliable questionnaire containing demographic characteristics and attitude as well as awareness questions. All the data were analyzed in SPSS 16 statistical software. Likert scale was used to measure awareness and attitude.

Results: In the present study, among the 68 final year dental students, 37 students (54.4%) were male 31 students (45/6%) were female the mean and standard deviation of the age of the participants was 25.12 ± 2.3 years. In this study, the mean and standard deviation of total attitude score of final year dental students was equal to 22.80 ± 6.74 and the total attitude score of final year dental students based on Likert Scale was lower than the average. Most of the students reported the quality of posterior composite training to meet practical needs as poor.

Conclusion: Based on the results, the awareness and attitude of final year dental students in relation to posterior composite restoration training was less than average and weak, respectively. There was no significant difference was observed between the knowledge and attitude scores with the gender and age.
