A. Ebadifar , Mr. Mohammadi , N. Valaee ,
Volume 18, Issue 4 (1-2006)
Abstract

Background and Aim: Compared to the information about educational responsibilities, there is not much information about the research skills and activities of the academics in dental schools. The aim of this study was to evaluate the research performance of the academic staff of the dental schools and their educational needs to promote their research skills.

Materials and Methods: This cross-sectional study was done by mailing a questionnaire to all of the members of Iran dental faculties. The questionnaires contained personal information like age, sex, place of employment, educational records, and additional questions like the workshops previously attended, and interests to attend certain workshops. To evaluate the research performance of the academic staff, the number of accomplished researches, the articles published in known national and international journals, their skills in using internet, and the number of attended workshops about research methodology were included in the questionnaire. The completed questionnaires were gathered and evaluated by descriptive statistics.

Results: From the questionnaires gathered, 436 were eligible to be included in the study, which formed 58% of the academic staff of dental schools. The results showed that 7.4% of the staff had more than 10 researches conducted, 15% had 5-10, 49.9% had less than 5, and 27.7 had no researches done. Considering the articles published in known national journals, 28.2% had no papers, 51.8% had 1-5 papers, and 20% had more than 5 papers. Regarding the number of articles published in known international journals, 77.5% had no papers, and 20.2% had 1-3, and 2.3% and more than 3 papers. The "preliminary research methods" workshop had the highest percent of participation (71.6%), and "Stata acquaintance" workshop had the least (0.7%). The participants were mainly interested to participate in three workshops, "English scientific writing" (26.3%), "principles of scientific writing" (17.5%), and preparing research proposals" (16.2%), respectively.

Conclusion: We concluded that the research skills and performance of the academic staff, though improved in the recent years, is still unsatisfying. In order to promote it, it is recommended to organize workshops about "research methodology", "scientific writing" and "preparing of proposals"

Volume 25, Issue 2 (4-2012)
Abstract

Background and Aims: The oral impact on daily performance (OIDP) is one of the oral health-related quality of life indices to measure physical, social and mental consequences of the oral health status. This study aimed to evaluate the OIDP index in patients referring to Tehran dental school.

Materials and Methods: Four hundred and ninety nine patients referring to patients' clinic in Dental School of Tehran University of Medical Sciences in spring 2011 participated in this study. They were interviewed for demographic factors including age, gender and level of education, and OIDP index questionnaire before receiving any treatment. Statistical analysis was carried out by means of linear regression modeling.

Results: 85.6% of patients confirmed that they had at least one oral impact on daily performance during the last 6 months. The most prevalent performances affected were eating (50.1%) and smiling and showing teeth without shame (12.8%). The mean OIDP score for the population was 5.6 ranging from 0 to 36. Linear regression modeling controlling for age, gender and years of education revealed that older patients and those with lower education had significantly higher OIDP scores.

Conclusion: The effect of oral health on daily performance was clear. The association among age, education and oral impact on daily performance indicates the need for more comprehensive preventive oral health care for adults with lower educational level.

The results showed a significant relationship between smoking, stress, and fatigue scores (P<0.05).
Conclusion: According to the high level of job stress in the dental prostheses technicians, this problem must be considered, minimized, and more attention should be paid to their psychological and emotional problems.

Volume 37, Issue 0 (3-2024)
Abstract
Background and Aims: The quality of sleep plays a significant role in the academic performance of dental students, especially in the clinical years. Identifying and treating students at risk of sleep disorders can reduce or limit the drop in academic performance. The purpose of this study was to determine the relationship between the sleep quality and educational performance of Rafsanjan dental Student-Iran.
Materials and Methods: The present study was a descriptive-analytical cross-sectional study that was conducted among all dental students in Rafsanjan University of Medical Sciences - Iran. This study was presented to all dental students in Rafsanjan by online questionnaire method on Pressline website. The questionnaire included demographic information and student number along with the Pittsburgh Sleep Quality Standard Questionnaire. The Pittsburgh Questionnaire examines the quality of sleep in the range of 0 to 21. The link of the questionnaire was made available to the students through Telegram, and the GPA of the total students was obtained by using the student number from the Vice-Chancellor of University Education. The data were analyzed with SPSS26 software. First, the data were analyzed with Smironov's kermograph test. The results of this test showed that the data distribution is not normal (P<0.05). Due to the non-normality of the data distribution, non-parametric tests such as K-score, Mann-Whitney, Kruskal-Wallis and Spearman were used.
Results: 151 students participated in the questionnaire of which, 73 were men (48.3%) and 78 were women (51.7%). The mean and standard deviation of the age of the subjects studied was 22.11±2.3 years. The overall average sleep quality score of dental students was equal to 8.13, which according to the questionnaire, students experience poor sleep quality. 86.1% of students had poor sleep quality. Examining the correlation between the sleep quality and academic performance showed that there was no significant relationship between them. Sleep quality had no significant relationship with gender, marital status, place of residence, and entry year (P<0.05).
Conclusion: The results of the present study showed that majority of dental students in Rafsanjan had low sleep quality. Although, there was no relationship between the quality of sleep and academic performance, it seems necessary to pay attention to the sleep status of these students in order to improve their sleep quality, which is an important factor in improving their health by administrators and Rizan health program.
