Hooman Zarif Najafi, Morteza Oshagh, Parisa Salehi, Hamid Keshavarz,
Volume 27, Issue 2 (6-2014)
Abstract

  Background and Aims: Orthodontic patients’ cooperation is a determining factor in treatment outcomes. The aim of this study was to evaluate the relationship between patient cooperation during orthodontic treatment with variables such as age, sex, life setting, treatment duration and functional and social discomfort experienced.

  Materials and Methods: Specimens were consisted of 100 orthodontic patients (36 males and 64 females) between 13-35 years old (average age: 22.57±1.69 years). Patients’ demographic traits, treatment duration and
functional-social discomfort by the orthodontic treatment were evaluated using a questionnaire answered by the patients or their parents. The degree of patient cooperation was assessed by the modified cooperation questionnaire (Orthodontic Patient Cooperation Scale [OPCS]) which was completed by an orthodontist. Data were analyzed using One-way ANOVA, T-test, intraclass correlation coefficient and Pearson Correlation.

  Results: No significant difference was found between the cooperation of male and female patients (P=0.867) and also between the cooperation of the patients who lived in the urban and rural setting (P=0.613). Treatment duration and compliance showed a low negative correlation which was not statistically significant (r=-0.155, P=0.127). Functional-social discomfort and compliance showed a low negative correlation which was not statistically significant (r=-0.118, P=0.244). No significant correlations were found between the compliance and age (r=0.002, P=0.988) and also the treatment duration and functional-social discomfort experienced
(r=0.164, P=0.105).

  Conclusion: Patient compliance appears to be a complex issue that cannot easily be predicted only by factors such as age, gender, life setting, treatment duration and functional-social discomfort experienced.

Pouyan Amini Shakib, Taraneh Movahhed, Hooman Keshavarz,
Volume 28, Issue 3 (10-2015)
Abstract

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.


Evaluation of last-year dental students' opinions about undergraduate curriculum: before the revision (2010-11)
Mohammad Reza Khami, Hooman Keshavarz, Samaneh Razeghi,
Volume 30, Issue 1 (6-2017)
Abstract

Background and Aims: Opinion of students regarding the content, structure and quality of their training is a fundamental part of holistic evaluation of curriculum, and serves as an important information resource in policy making. In the present study, we aimed to contribute to the development, assessment and evaluation of the new national dental curriculum through evaluation of last-year dental students’ opinions regarding undergraduate dental curriculum.

Materials and Methods: This cross sectional questionnaire survey was done in 2010-2011 academic year. The target population was last-year dental students in 15 Iranian state dental schools. In these schools, all last-year dental students were invited to participate in the study. The chi-square test served for statistical analyses.

Results: In total, 432 students (68.4% female) participated in the study. Of the respondents, 72.4% (60.7% of male and 77.6% of female, P=0.001) believed that their undergraduate dental training had been completely inadequate or inadequate. Only about one third of students believed that educational methods during their undergraduate dental training had been appropriate or completely appropriate.

Conclusion: In general, it seems that undergraduate dental training from students’ view point has not been appropriate in terms of both content and method. The results show the necessity of revision of national undergraduate dental curriculum.

Ehsan Aliabadi, Esfandiar Keshavarz,
Volume 33, Issue 1 (7-2020)
Abstract
Background and Aims: The inferior alveolar nerve block (IANB) is the most frequently used technique for mandibular anesthesia. Due to the many factors which can cause its failure, the aim of this study was to evaluate the efficacy of experience and knowledge in the success rate of IANB technique.
Materials and Methods: : In this study, 115 students of Shiraz Dental school were participated in two groups. One group contained 53 novice students and another group 62 students with one year experience in IANB injection. Each student accomplished injection once and then success or failure of the injection was examined. In order to evaluate the students’ knowledge, each student was asked to fill out a questioner including 6 questions related to the instruction of the injection. Data were then collected, coded, and analyzed by SPSS18 using Chi square with a significant level of 0.05.
Results: The rates of knowledge in novice and experienced group were 71.6% and 86.3%, respectively. The success rates of IANB were 47.1% in novice group and 64.3% in experienced group. The success rates of IANB and knowledge were significantly higher in the experienced group compared with the novice group. (P=0.02 and P=0.01, respectively) There was no significant difference between male and female (P=0.06).
Conclusion: The results showed that knowledge and experience could play an important role in the success rate of IANB technique.
