The students’ self-confidence level is a key factor affecting the success of endodontics learning. This study aimed to determine the confidence level of dental students who performing root canal treatment at Rafsanjan University of Medical Sciences in 2021.

In this cross-sectional study a questionnaire including demographic information, endodontic experience, attitude toward confidence in performing different stages of root canal treatment, and suggestions for improving the quality of endodontic education was distributed to dentistry students of 54 5th and 6th-year in the last month of the academic semester. Data were analyzed using t-test, Pearson, and ANOVA tests (α = 0.05).

According to the results, from 49 dental students, 24.5% reported the first cases of root canal treatment to be severe. The lowest confidence was reported for finding all root canals in teeth with multiple root canals, preparing access cavity and understanding and managing root canal treatment risks. According to the results of chi-square analysis test, the total confidence score between 5th and 6th year students was not significantly different (p value = 0.648). Also, the relationship between general self-confidence and students' self-confidence level was not seen (p value = 0.372). There was no significant relationship between the Confidence level and age, academic year, the difficulty level of the first endodontic treatment, and number of endodontic treatments (p value > 0.05).

Students had lower self-confidence finding all the canals in multi-canal teeth, how to properly manage the treatment risks, and preparing the access cavity. Endodontics training should also be improved by increasing clinical sessions and using recent advances in endodontics.

The tools used in dentistry become contaminated after treatment. The most common method of sterilizing them is autoclaving. The aim of the present study was to evaluate the accuracy of type B autoclaves in Rafsanjan dental clinics in 2019-20.

In this descriptive cross-sectional study, 42 dental clinics were examined. In order to evaluate the performance of autoclaves, SPORVIEW biological indicator and incubator with a temperature of 55-60 º C were used. Data were analyzed using the Mann-Whitney U test and Chi-square test.

The present study showed that 85.69% of the autoclaves performed the sterilization process correctly and 14.31% of them failed to perform this process.

The results showed that type B autoclaves of dental clinics in Rafsanjan have a good performance for sterilizing instruments.

Background and Objectives The Coronavirus disease 2019 (COVID-19) pandemic has severely disrupted medical education. Distance learning is a way to reduce this problem. The Vice Chancellor for Education of Rafsanjan University of Medical Sciences has tried to implement distance education as much as possible by using a program that includes perspective, strategy and operational plan. With the implementation of empowerment courses, policy making, informing, providing the necessary tools and continuous monitoring of the program, 5075 educational activities have been registered on Navid's learning management system. But there are still issues that need to be addressed: activating simultaneous online learning, increasing educational interactions, and producing SCORM-(Sharable Content Object Reference Model) based educational content.

Professional development of faculty members is one of the aspects of improving academic quality and an effective factor in improving the quality and empowerment of faculty members in educational system. The purpose of this study was to determine the needs of the faculty members of Rafsanjan University of Medical Sciences by applying agreement approach.

This descriptive study was conducted among 57 faculty members of Rafsanjan University of Medical Sciences in 2018, using census method, with the aim of identifying needs in five areas: research, education, personal skills and competencies, information technology and evaluation, and management and executive needs. Needs assessment was conducted using the Delphi technique in three rounds. The results were reported as mean, standard deviation, median in separate tables and priority needs were determined in each area.

The most important needs in the five areas included getting to know writing articles in English, searching for electronic resources and databases, introducing new teaching methods in the classroom, principles and practices of learning, language courses such as speaking, familiarization with the translation technique, analysis methods and structural equations with LISREL and AMOS, softwares for analyzing qualitative research, communication skills and classroom management.

Accordingly, design, implementation and evaluation of educational programs is recommended by the Education Development Center and other related units of Rafsanjan University of Medical Sciences.

Despite their ascribed intellectual ability and achieved academic pursuits, the dental student’s academic achievement is influenced by learning motivation. This study in an Endeavour aimed to examine the learning motivation factors of dental students of Rafsanjan University of Medical Sciences.
In this descriptive-cross sectional study, 120 dental students completed the questionnaire which comprised of 33 questions regarding intrinsic and exogenic motivational factors. Demographic factors (gender, marital and native status, employment year of study) were examined. Data were analyzed by SPSS17 software. Descriptive and analytical statistical methods (t-test, Pearson correlation and ANOVA statistical tests) were used.
The mean of the achieved scores in the domains of learning motivation was 2.98±0.32 out of 5,which was considered as moderate level. Comparing the means of the intrinsic (3.16±0.48) and exogenic (2.82±0.44) domains showed significant differences (P Educational motivation of Rafsanjan dental students was moderate. In learning, intrinsic motivational factor was more than exogenic factors in male students.

Pain control is essential to the behavioral management of children in pediatric dentistry. Effective anesthesia plays a key role in this regard, especially in pulp therapy. In order to achieve successful anesthesia, the type of analgesics and injection techniques should be considered. The present study aimed to compare the anesthetic efficacy of articaine infiltration and lidocaine inferior alveolar nerve block in the pulp therapy of lower primary molars.
This randomized, crossover, triple-blind clinical trial was conducted on 64 children aged 4-10 years, who required the bilateral pulp therapy of the lower primary molars. Subjects were randomly divided into two groups. Treatment was performed for two sessions, and one lower primary molar was treated in each session. In the first treatment session, subjects in group A were injected with lidocaine inferior alveolar nerve block, and in the second session, they were injected with articaine infiltration. In group B, all the procedures were similar to group A. In the first treatment session, subjects in group B were injected with articaine infiltration, and in the second session, they were injected with lidocaine inferior alveolar nerve block. Pain intensity was measured upon the initiation of the pulp exposure using the visual analogue scale (VAS). Data analysis was performed by crossover analysis, paired t-test, and independent two-sample t-test.
During the study period, mean pain intensity in the children treated by lidocaine inferior alveolar nerve block was significantly lower compared to those treated by articaine infiltration. However, the two techniques had no statistically significant difference in the children aged 4-6 years and the treatment of the first primary molars.
According to the results, lidocaine inferior alveolar nerve block has higher anesthetic efficacy in the pulp therapy of the lower primary molars compared to articaine infiltration. On the other hand, articaine infiltration could be a proper alternative to lidocaine inferior alveolar nerve block in the children aged 4-6 years and the treatment of the first primary molars considering its greater ease and lower risk.

Detection of horizontal root fracture is a clinical difficulty that can only be detected through radiography in most cases. This study aimed to assess the efficacy of reverse contrast option of digital radiography in detection of horizontal root fracture.
In this ex.vivo study, 85 permanent maxilla single root central teeth were mounted in a dry skull alveolar socket. Conventional periapical and digital radiographs were taken in two vertical angles (40 and 55 degrees). Then, horizontal fractures were created in the middle-third of the roots using a hammer and the two pieces were stuck to each other. Afterwards, the fractured teeth were mounted in the dry skull alveolar socket and all radiographs were repeated in the same position. Digital images were processed with reverse contrast option. All radiographs were assessed by two radiologists and one endodontist. Two weeks later, 10% of the radiographs were assessed by one radiologist. The data were analyzed using the SPSS statistical software (p>0.05).
There was no significant difference between digital and reverse contrast images in detection of horizontal root fractures (p>0.05) and both were better than conventional radiographs (p The reverse contrast option and digital radiography showed equal diagnostic accuracy, which was higher compared to conventional radiography. Additionally, 40-degree radiographs were better compared to 55-degree ones.

According to the importance of health systems, assessing the different aspects of health care service quality comes into necessity. This assessment has not been done in Rafsanjan School of Dentistry yet. The purpose of this study was assesing and analysing the existing gap within service performance quality in clinical departments of this school.
This descriptive study was carried out in 2016-2017 academic year. Participants were 180 patients of clinical departments of Rafsanjan Dental School. Data were collected by SERVQUAL standard questionnaire which assesses quality of services in six dimentions and 31 questions and then analysed. In data analysis, independent t- test, paired t -test and one-way ANOVA were used.
A significant gap (p Regarding to lack of relative satisfaction which was seen in all dimentions, measures, and clinical departments, requirement of effective planning for reducing each departments gap and promoting service quality look urgent.
