Introduction: Self-assessment is one of the methods of benchmarking dental graduates of the acquired skills  and identify the strengths and weaknesses of the current student and educational system. The purpose of this study was to evaluate the viewpoints of final-year students of Qazvin Dental School regarding their acquired clinical skills based on the educational program.
Methods: The type of study was descriptive cross-sectional. In this study, the clinical skill level of dental students was evaluated using a 45-item questionnaire (from the skills of 9 clinical departments). Data were analyzed by SPSS software version 16 using t-test.
Results: 24 students (10 males and 14 females) were included in the study. In general, the mean of students (out of 5 scores) was 3.41±0.30 which was in good level. There was a significant difference between the students' ability in different departments (P = 0.000). The highest ability was in endodontics (4.00) and the lowest in oral disease and diagnosis (2.98). There was no significant difference in total abilities between men and women, but the ability of women in the endodontics ward was higher than men (P = 0.002).
Conclusion: The level of ability of the students from their point of view in this study was good. There was also a difference in the skills of girls and boys in educational settings. The results of this study can be used for evaluation of strengths and weaknesses and planning for promoting education in Qazvin Dental School.

Introduction: Until now, many surgical sutures have been used for pterygium surgery, but it has not yet been determined which suture thread is preferable for pterygium surgery. In this study, we compared the results of using two surgical sutures, Nylon and Vicryl.
Methods: This study was conducted as a Randomized Clinical Trial (RCT) at Shahid Sadoughi Hospital. Seventy patients who were referred and met the criteria for pterygium surgery were assigned to two groups, A and B, each consisting of 35 individuals.  Group A utilized the Nylon sutures while Group B utilized the Vicryl sutures. The examinations were performed in terms of study variables according to a questionnaire pre-determined by an ophthalmologist's assistant on the 1st day, 7th day, 4^th, and 8th week after operation. The collected data were entered into STATA14 software and considering the qualitative nature of most dependent variables, the collected data were analyzed using Chi-square test.
Results: According to all the obtained results, it could be concluded that a certain sutures could not be chosen especially better than other suture, because each one had its own advantages and disadvantages. But on a case-by-case basis, Vicryl suture could be recommended for patients who had come to the hospital from far away cities because it did not need to be pulled by the doctor and it created the feeling of the presence of a foreign body in the patient's eye, because it reduced the need to return to the hospital.
Conclusion: In this study, we compared vicryl and nylon sutures in pterygium surgery, and for the first time among other similar studies, we investigated the rate of knot untying of the sutures, and came to the conclusion that each of the nylon sutures and Vicryl has its advantages and disadvantages, but due to the fact that in the Vicryl thread group, the presence of a body was felt less and it did not need to be pulled, we recommended it for the patients visiting from distant cities. It is suggested to compare vicryl and silk sutures in order to find the most suitable suture for pterygoid surgery.
