Background and Aims: The objective of the present study was to investigate knowledge and attitude of senior dental students towards HIV/AIDS. Its result could help in promotion of education.

Materials and Methods: This educational research was carried out in two state dental schools in Tehran. The senior dental students in Tehran and Shaheed Beheshti dental schools were asked to fill in a self-administered questionnaire regarding their age, gender, parents' job, knowledge and attitudes towards treatment of patients with HIV/AIDS in Autumn semester 2007. Fifty five dental students (83%) including 27% male and 73% female in Shaheed Beheshti and fifty five dental students (85%) including 34% male and 66% female in Tehran dental schools were participated. The score for knowledge and attitude of the students were calculated separately. The data were analyzed using Independent sample t-test.

Results: The mean percentage of knowledge and attitude scores were 76.5% (at rang 1-3) and 50% (at range 1-5), respectively. Nearly all of the students believed that all patients should be considered as HIV positive in dental practice, while 49% preferred to refer HIV positive patients. Knowledge and attitude of students were not significantly associated with the gender and knowing HIV positive person (P>0.05).

Conclusion: There is a need to improve knowledge and attitudes of dental students towards HIV/AIDS. It is suggested to emphasize on this subject in dental schools curriculum in Iran.

Background and Aims: The present study aimed to evaluate the barriers to the production of scientific dental articles in dental schools in Iran based on the opinions of dental postgraduate students.

Materials and Methods: A self-administered questionnaire was distributed among postgraduate students of all Iranian dental schools in June 2010. The respondents rated their agreement with eight sentences about what hinder them from producing scientific dental articles based on a 5-grade Likert scale. The data were analyzed using Chi-square test.

Results: Totally, 270 filled questionnaires from 14 dental schools were received. Of all respondents, 53% were male, the mean age were 29.6 ± 3.8. About half of the respondents reported at least one published article. Less than half of the respondents reported producing an article from undergraduate thesis more women than men and more younger than older students (P<0.03). About two-third of the respondents rated absence of an English editing center, no financial incentives, no appropriate environment, and no competency for scientific writing as most prevalent barriers to the production of scientific dental articles.

Conclusion: To expand the share of Iran in the production of scientific dental documents, the potential of postgraduate dental students must be regarded and suitable condition for scientific writing must be provided. Specifically, based on the findings of the present study, provision of an English editing facility, establishing financial incentives, and providing the students with appropriate environment and efficient scientific writing education are of utmost importance.

  Background and Aims: Root canal therapy is one of the most important parts of a general dentist's profession. The aim of this study was to evaluate the radiographic quality of root canal therapy performed by under graduated students at Yazd dental school.

  Materials and Methods: Records of patients, who were referred to the endodontic department during 2010-2012 and treated by undergraduated students, were divided into three groups by the numbers of canals and 80 specimens from each group were randomly evaluated. For the assessment, the quality of accomplished treatments, the indices: length, taper, and density of obturation were used and the errors during root treatment were recorded. Data were analyzed using Fisher's exact test and Chi-square.

  Results: According to the results, 155 (64.6%) records had appropriate filling length, whereas 55 (22.9%) were underfilled and 30 (12.5%) were overfilled. The acquired difference was statistically significant among three groups. (P<0.001). 187 (77.9%) records had adequate taper and 157 (65.4%) records had adequate density. The difference in the evaluating of taper (P=0.976) and density (P=0.879) was not significant. Totally, 39.2% of specimens had all the properties of an appropriate root canal treatment.

  Conclusion: The results of the present study can be used to identify weaknesses in the treatment of different educational groups and help them to achieve a proper planning to improve the quality of endodontic treatments.

Background and Aims: Choosing an appropriate style of teaching-learning by educators is a way to reach high quality education. The objective of this study conducted in Babol Dental School was to compare dental students, satisfaction of teaching theoretical general pathology course by means of a combination of lecture and work in small groups with their satisfaction of teaching the course by means of only lecture.

Materials and Methods: This study was performed in the second semester of school year 2011-12 and 2012-13. In 2012 (intervention group, response rate=92%), the teaching of theoretical general pathology course was implemented by means of a combination of lecture and work in small groups, but in 2013 (control group, response rate=81%) by means of only lecture. An anonymous self-administered questionnaire was used to assess students, satisfaction of the teaching methods. To compare the mean total score of satisfaction (ranging from 18 through 90) between the two groups, T-test was used.

Results: Comparing the mean total scores between the two groups revealed that students, satisfaction of the combined teaching method was significantly higher (P<0.001). The difference of satisfaction between genders (separately for each group) was not significant in combination group and lecture group (P=0.63 and P=0.87,   respectively).

Conclusion: Regarding learning, combining lecture with other teaching methods such as work in small groups may increase health sciences students' satisfaction. In regard to teaching theoretical general pathology course, our findings could confirm this hypothesis.

Background and Aims: Supporting the preventive approach is important in training future dentists. The purpose of the present study was to evaluate the knowledge, attitude and practice of senior dental students regarding non-invasive management of dental caries.
Materials and Methods: A cross-sectional study was conducted in 2019 using total sampling method and a valid and reliable questionnaire. Knowledge, attitude and self-reported practice of senior dental students regarding caries risk assessment (CRA) and management of lesions in two paper patients were assessed. The data analysis was performed using SPSS20 and the descriptive and analytical statistics were reported.
Results: In overall, 86 students (response rate=91%) were responded. In the knowledge section, caries history in the previous year, having frequent fermentable carbohydrate, xerostomia, and low socio-economic status were considered by more than half of students as factor for caries risk assessment. More than 90% of students had a positive attitude towards CRA in children. Nearly 50% of students tend to restore enamel lesions in proximal and occlusal surfaces in high-risk scenarios. There was significant association between the OHI instruction and debris index improvement (P=0.04) in the integrated comprehensive care clinic (TUMS). The linear regression analysis showed that there was no significant association between the demographic characteristics, place of education, previous course on the level of knowledge and attitude.
Conclusion: Senior dental students despite their general knowledge and positive attitude toward caries risk assessment, tended to aggressively manage the incipient lesions in the enamel and DEJ. Delivering prevention as integrated in the comprehensive care unit in order to improve oral hygiene status of patients is recommended.

Background and Aims: For dental students, communication skills are essential to effectively transfer the necessary information to the patient and meet the patient’s needs and expectations. Therefore, this study was conducted to determine the patient communication skills of dental students at Islamic Azad university of Isfahan in 2021.
Materials and Methods: In the present cross-sectional analytical study, an online standardized questionnaire DCCC (Dental consultation communication checklist) was provided to all clinical dental students applying a census sampling method. In total, from 248 clinical dental students, 230 students participated in the study (response rate=92.7%). The questionnaire included five dimensions of introduction, medical history, clinical examination, closure and patient. In order to determine the patient communication skills, its dimensions, and the association between patient communication skills and students’ demographic characteristics, friedman test, analysis of variance, independent t-test and a linear regression model were used for statistical analysis.
Results: The mean score of total communication skills of the students (117.16±15.6) was above average which was obtained from the maximum score of 155. There was a significant difference between the dimensions of communication skills (P<0.001). The highest scores were assigned to the clinical examination, patient, medical history, introduction and closure, respectively. No significant relationship existed between the score of students' communication skills with gender (P=0.08), age (P=0.17), marital status (P=0.19), and educational background in psychology (P=0.07). No significant relationship revealed between the total score of communication skills (P=0.92) and its dimensions (introduction P=0.79, medical history P=0.90, clinical examination P=0.77, closure P=0.35, and patient P=0.85) with the students’ academic year.
Conclusion: The total score of dental students’ communication skills and all its dimensions was above average. However, students reported poorer performance in dimensions of introduction and closure than the other dimensions. Therefore, it is recommended to design and implement educational interventions specially to improve the dimensions of introduction and closure.
