Background: Smile esthetics can be subjective. This study aims to assess the effect of culture/geographic location on judging smile esthetics by comparing the perception of smile characteristics between American laypersons (Western culture) and Iranians (Eastern). Materials and Methods: One hundred residents from each country were recruited for this analytical cross-sectional study. A frontal picture of a posed smile with standard norms which are mentioned in the Contemporary Orthodontics textbook by William R. Proffit was selected. Adobe Photoshop 7 was used to alter midline diastema, gingival display (GD), maxillary midline-to-face discrepancy, buccal corridor (BC), and smile arc. Images were given to groups to determine the most attractive and acceptable smile. Data were analyzed by Chi-square, Mann-Whitney, and Spearman correlation coefficient in SPSS-22 (α = 0.05). Results: Americans were less critical in judging diastema (P < 0.001), GD (P = 0.013), and BC (P = 0.004) for smile attractiveness than Iranians. No difference was between the two groups in choosing the acceptability threshold and determining the most attractive smile except for BC (P = 0.002). Conclusion: Overall, Americans were more tolerant of variations in smile characteristics than Iranians. Both groups agreed on most smiles. Therefore, it seems that it is reasonable to use similar standards for smile characteristics while considering the small differences. [ABSTRACT FROM AUTHOR]

Background: Since general dentists (GDs) usually act as the primary referral source for the patients in need of orthodontic treatments, having the proper knowledge and understanding of the accurate diagnosis of clinical situations is very important. The aim of this study was to assess GDs about the identification of orthodontic treatment needs and their referral practices. Materials and Methods: This descriptive and analytical cross-sectional study was carried out in Iran 2020.A questionnaire consisting of three main parts was designed and distributed electronically among GDs. The first section included ll image and scenario-based questions meant to assess the ability of GDs to correctly diagnose the orthodontic treatment needs of the patients. The next two parts were to assess the dentists' knowledge of the necessity of referral to an orthodontist with ll questions, and the proper timing of orthodontic treatments with 8 questions. Data were analyzed using SPSS 26, by conducting Mann-Whitney, Kruskal-Wallis, and correlation tests a = 0.05. Results: Among 384 participated dentists, 50.3% (193) were female.The mean score of knowledge was 17.3 ± 3.5 out of 30. The highest percentage of good knowledge (70% of range) was related to the diagnosis of orthodontic problems, while the lowest one belonged to the referring pattern. There was a weak positive correlation between the working experience and the proper timing of referral (R = 0.15, P = 0.004 (. Kruskal-Wallis test also showed a significant difference between the total knowledge scores (P = 0.04) and the knowledge of the proper timing of treatment (P = 0.04) based on the age groups of participants. Eighty-seven percentage (n = 334) reported that they would refer the patients in need of orthodontic treatment. Conclusion: The knowledge level of orthodontic treatment needs among GDs was moderate, thus emphasizing the importance of planning more educational courses for them to improve their knowledge, thus reducing the possible detriments of postponed or inaccurate treatments.

Purpose: To assess the prevalence of dental trauma (DT) and its associated factors in 9- to 14-year-olds.Subjects and Methods: A cross-sectional survey was carried out through clinical examination of the permanent incisors and canines of 907 schoolchildren (9 to 14 years old, average age = 11 ± 0.5 [SD] years, 55% female and 45% male) enrolled in 20 public schools in Isfahan, Iran. The demographic data, history and cause of trauma were recorded during patient interviews and with a structured questionnaire filled in by their parents. The overjet, lip coverage, and visible signs of DT (permanent incisors only, similar to the classification used by the US National Health and Nutrition Examination Survey 1988-1994, NHANES III) were recorded. DT in permanent canines were also recorded.Results: Approximately 36% (n = 325) recalled the occurrence of dental trauma, but only 23.8% (n = 216) of children had visible signs of dental trauma to the permanent incisors (girls [18.8%], boys [29.9%], OR = 0.54; 95% CI 0.40- 0.74; p = 0.000). The maxillary central incisors were commonly injured (69.5%). The most frequent types of injuries were the enamel fracture (59.0%), craze lines (16.3%), and enamel and dentin fracture (13.4%). Tooth avulsion was seen in 0.7%. No significant association was found between dental trauma and increased overjet of > 3 mm (p = 0.328), but a tendency was identified for overjet > 5 mm (OR = 1.51; 95% CI 0.89-2.58; p = 0.060). The relationship between DT and lip coverage was statistically significant (OR = 1.63; 95% CI 1.18-2.25; p = 0.003). Violence (30%) and fall (22.7%) were the main causes of DT.Conclusion: The prevalence of DT in permanent incisors was high (23.8%) and significantly lower in girls. The association between DT and lip coverage was significant. There was no association between DT and increased overjet of > 3 mm. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the psychometric properties of an oral-health related quality of life (OHRQoL) instrument for application in the population of Iranian adolescents and to assess the discriminate and convergent validity and reliability of the Persian version of the Child Oral Health Impact Profile (COHIP) in a representative sample of this population. Materials and Methods: Using multistage stratified sampling, 597 schoolchildren aged from 13 to 18 years living in the city of Isfahan were recruited to complete the Persian COHIP questionnaire. They were also examined for dental caries and malocclusion by two trained, calibrated examiners. Results: Overall COHIP scores ranged from 15 to 135 (mean ± SD: 103.6 ± 18). Sixty-six percent of the students experienced at least one frequent oral health-related impact over the past three months. The Cronbach alpha coefficient was 0.89 for the overall score. Discriminate validity was supported by the significant difference between COHIP scores in the caries-free group and the others (P = 0.01). In addition, the questionnaire was able to differentiate among the groups by various degrees of need for orthodontic treatment (P < 0.01). Convergent validity was confirmed by significant association between the quality of life scores, the self-perceived health and oral health ratings and the self-perceived treatment need (r = 0.36, 0.57, -0.40). Conclusion: The Persian COHIP demonstrated acceptable psychometric properties for the descriptive purposes. Some discrepancies observed between the clinical data and quality of life status were confirmed by the perceptual identity of such indices influenced by several overt and covert variables.

Aim: To determine with a cross-sectional study the prevalence of orthodontic treatment need using the Dental Aesthetic Index (DAI). Subjects and Methods: Using a stratified sampling method in private and public schools in Isfahan, Iran, 748 subjects were examined and divided into three age groups: 11 to 14, 14 to 17, and 17 to 20 years (355 females and 393 males, 15.11 ± 2.23 years), including 20 subjects with history of orthodontic treatment. DAI scores were recorded in those without history of orthodontic treatment (n = 728, 340 females and 388 males). The proportions of subjects within sexes needing treatment, as defined by having DAI scores of at least 31, were compared using the chisquare test. The chi-square test was also used to test for any difference for DAI treatment categories in different age groups and also to test for sex dimorphism. Results: The mean DAI score was 26.14 (SD = 7.64) points (95% CI, 26.60 to 26.72). On the whole, 54.5% showed no need or slight need for treatment. In 23.6%, the need for treatment was elective. However, in 11.0%, treatment was highly desirable and 10.9% showed very severe malocclusions and treatment was mandatory. There was a significant difference between sexes with regard to DAI treatment need categories (chi-square = 10.10, df = 3, P < .05). There was no significant difference between different age groups with regard to DAI treatment categories (P > .05). Conclusion: According to our findings, 21.8% of the evaluated Iranian school children in our sample had a DAI score above or equal to 31 points, suggesting highly desirable or mandatory orthodontic treatment need.

Aim: To determine the malocclusion complexity and orthodontic treatment need in urban Iranian schoolchildren using the Index of Complexity, Outcome, and Need (ICON) and the Index of Orthodontic Treatment Need (IOTN) and to also assess the relationship between these indices. Methods: The study sample comprised 502 individuals (253 girls and 249 boys, 11 to 14 years of age), of whom one girl and five boys already had an orthodontic appliance at the time of the survey. In those individuals not wearing orthodontic appliances (n = 496), the definitive treatment need (ICON > 43) and compartments of the ICON were defined and compared between sexes. The Aesthetic Component and Dental Health Component (DHC) of the IOTN were also recorded. Scatter plots and Spearman rank correlation coefficients were used to explore the relationships between the ICON and DHC and the Aesthetic Component (AC) of the IOTN. Results: According to ICON, DHC (IOTN), and Aesthetic Component (IOTN), 46.6%, 36.1%, and 17.9%, respectively, of the studied children needed orthodontic treatment; however, only 1.1% wore an appliance. In terms of complexity, 26.4% of the studied individuals were considered to have a difficult or very difficult malocclusion. With regard to treatment needs, significant correlations existed between the ICON scores and DHC (IOTN) (r = 0.93) and between the ICON scores and the esthetic component (IOTN) (r = 0.96). The threshold for treatment need was lower in the ICON than in the IOTN. Of the children who were classified in the borderline category of the IOTN (DHC = 3), 52.0% were in need of treatment according to their ICON score (ICON > 43). No sex difference was found for treatment need (ICON > 43, P > .05) and treatment complexity (P > .05). Conclusion: According to the ICON, 46.6% of the Iranian schoolchildren need orthodontic treatment. ICON is a good substitute for the IOTN, yet it results in a lower treatment-need threshold.

Background: Malocclusion is a common oral health problem and can affect the psychosocial well-being in the long term. Therefore, in the recent decades, demand for orthodontic treatment to correct malocclusion has greatly increased worldwide. This systematic review and meta-analysis was undertaken to assess existing evidence on the prevalence of orthodontic treatment need in Iran. Materials and Methods: National and international databases were searched for articles on the prevalence of orthodontic treatment need using index of orthodontic treatment need (IOTN) and dental aesthetic index (DAI). The required data were completed by hand-searching. After applying the inclusion and exclusion criteria, the quality of articles was checked by a professional checklist. Data extraction and meta-analysis were performed. A random effects model was employed, and publication bias was checked. Results: From a total of 443 articles that reported orthodontic treatment need in Iran, 24 articles were included in the meta-analysis process. Meta-analysis was performed on components of IOTN and DAI. The pooled prevalence of orthodontic treatment need based on Dental Health Component and Aesthetic Component of IOTN and DAI was 23.8% (19.5%-28.7%), 4.8% (3.3%-7%), and 16.1% (12.3%-20.8%). The results were found to be heterogeneous (P < 0.05). Conclusion: The results of this study revealed that orthodontic treatment need was not high in the Iranian population. Considering the differing prevalence of orthodontic treatment need based on normative index and self-perceived index, it is essential to improve the people's awareness of malocclusion and its side effects on their oral and general health.

Background: To determine patient orthodontic treatment need, appropriate self-perceived indices are required. The aim of this study was to assess the sensitivity and specificity of esthetic component (AC) of the index of orthodontic treatment need (IOTN), oral esthetic subjective index scale (OASIS), and visual analog scale (VAS) through dental health component (DHC) IOTN as a normative index to determine the more appropriate self-perceived index among young adults. Materials and Methods: In this cross-sectional study, a sample of 993 was randomly selected from freshman students of Isfahan University. Those with a history of orthodontic treatment or current treatment were excluded. DHC was evaluated by two inter- and intra-calibrated examiners. Data for AC, OASIS, and VAS were collected through a questionnaire completed by students. Descriptive statistics, Mann--Whitney U-test, and Spearman correlation test, were used for data analyses. Sensitivity, specificity, positive and negative predictive values of self-perceived indices were calculated through DHC. Results: Sensitivity of AC, OASIS, and VAS for evaluating definite orthodontic treatment need was calculated at 15.4%, 22.3%, and 44.6%, respectively. Specificity of these indices for evaluating definite orthodontic treatment need was calculated at 92.7%, 90.5%, and 76.2% percent, respectively. All self-perceived indices had a significant correlation with together and with DHC (P < 0.01). Among demographic factors, there was weak but significant correlation only between mother's educational level and VAS (P < 0.01). Conclusion: Due to the sensitivity and specificity of the three self-perceived indices, these indices are not recommended for population screening and should be used as adjuncts to a normative index for decision-making in orthodontic treatment planning.

Background: Information regarding the prevalence of surgical osteotomies used for the correction of dentofacial deformities in Iran is lacking. Materials and Methods: This retrospective cross-sectional study assessed the distribution of orthognathic surgeries performed (2011--2015) at major University hospital in Iran. Records of 103 orthognathic surgery patients were assessed (58 female, 45 males, aged = 23.47 [6.44] years). Results: Class III malocclusion (incisor classification, 45.6%) and Class II skeletal pattern (based on ANB angle, 51.5%) were the most prevalent type. Overall, 4.8%, 51.5%, and 43.7% of subjects had Class I, II, and III sagittal skeletal patterns, respectively. The most prevalent (66%) osteotomy was the bimaxillary osteotomy. The frequencies of reported and corrected asymmetries in the lower third of the face (35%) were similar among patients with different malocclusions ( χ² = 4.134, P = 0.127) or sagittal skeletal patterns ( χ² = 2.133, P = 0.344), as well as between Class II and III malocclusions (P = 0.125) or sagittal skeletal patterns (P = 0.149). Conclusion: Compared to Class II subjects, Class III (malocclusions or sagittal skeletal patterns) subjects had more bimaxillary osteotomies, indicating the higher prevalence of skeletal discrepancies affecting both jaws in Class III subjects.

Objective: Oral health status particularly maxillofacial disorders in adolescents can affect different aspects of the quality of life. This study aimed to assess the age-related quality of life of students in two age groups of 11-14 years and 14-18 years to evaluate its correlation with orthodontic treatment need in adolescents in Isfahan. Methods: This cross-sectional study was conducted on 11-18 year-old middle school and highschool students. Subjects were selected via two-stage stratified random sampling from 30 schools in different areas of Isfahan city. After examination by two calibrated clinicians, Dental Health Component of Index of Orthodontic Treatment Need (DHC-IOTN) was recorded for all subjects. The Oral Health Related Quality of Life (OHRQoL) was assessed using self-reported Child Perception Questionnaire (CPQ) in 11-14 year-olds and Child Oral Health Impact Profile (COHIP) in 14-18 year-olds. After descriptive analyses, the correlation between the DHC-IOTN and the quality of life score of subjects was assessed using the Spearman's correlation test and the Mann Whitney U test. Results: A total of 1,227 students were evaluated. The mean and standard deviation (SD) was found to be 18.3 (13.7) for CPQ score in 11-14 year olds. For COHIP score it was found to be 103.6 (18) in 14-18 year olds. A total of 22% from the 604 students examined in the first group, and 17% of 570 students in the second group definitely needed orthodontic treatment. Significant differences existed in the mean quality of life score among the three groups requiring orthodontic treatment in the two age groups (p<0.05). The correlation between the malocclusion severity and quality of life subscales was weak. Conclusion: Based on the results, malocclusion significantly affects the dental function and social and emotional domains of quality of life. However, considering the role of confounders, studies with condition-specific formats of the questionnaire are required to assess the correlation of malocclusions with the quality of life after controlling for other factors.

Background: A comprehensive system of assessing orthodontic need requires the integration of normative clinical measures with patient-based indicators. This study sought to discover weather an oral health-related quality of life measure or Aesthetic Component of Index of Orthodontic Treatment Need (AC-IOTN) could be used as a predictor of orthodontic treatment need. Factors affecting the judgment of patient and dentist about this need are discussed. Materials and Methods: Oral examination on 597 Iranian students between 13 years and 18 years was done to reach the grade of Dental Health Component (DHC). The Child Oral Health Impact Profile (COHIP) and AC-IOTN were recorded. The diagnostic values of subjective tests were assessed. Multiple logistic regressions were applied to investigate the role of variables in the persons' perceptions. Results: Half of the 570 eligible students did not need orthodontic treatment either on professional or self-assessment; 60% of patients with definite need had a distinct impact on their quality of life. The specificity of AC to detect the healthy persons was excellent (0.99) but its sensitivity was low (0.08). COHIP score gave a better sensitivity but its specificity was 50%. Caries experience, quality of life, father's education, and brushing habits were the factors relating to the same judgment of persons and dentists (P < 0.02). Conclusion: Regarding the discrepancies between two assessment methods, present instruments did not meet the predictor's competencies. The patient-based methods could not substitute the professional assessment, but by identification, the persons with higher impacts would benefit the prioritization process. [ABSTRACT FROM AUTHOR]

Background and Aims: Normative need assessments should be substituted or integrated by patient-based outcome measures regarding their shortages in health-oriented approach . This study aimed to assess and compare the ability of an index of oral health-related quality of life measured by Child Oral Health Impact Profile (COHIP) questionnaire and the Aesthetic Component of Index of Orthodontic Treatment Need (AC-IOTN) to identify the normative need to orthodontic treatment using Dental Health Component-IOTN in a sample of the Iranian adolescents. Materials and Methods: Target population of this cross-sectional analytic study was 597 of the 13 to 18 year-old schoolchildren enrolled in middle and high schools of the city of Isfahan, Iran. They completed the COHIP questionnaire and then were examined by two calibrated trained dentists (agreement coefficient:0.9) to record the DHC grading. The students scored their AC in according to the images of the scale. The association between subjective indicators and clinically defined need were evaluated by the correlation analysis and the statistics for the diagnostic validity of tests. Results: Of 568 examined students, 16.7% and 2.1% had definite need according to DHC and AC criteria, respectively. 10% of orthodontic patients had perceived distinct impact on their quality of life. The significant association (P=0.001) between the severity of malocclusion and quality of life was at moderate level by AC (R=0.37), but it was not convincing enough by DHC (R=0.16). The specificity of AC to detect the healthy ones showed to be excellent but its low sensitivity disabled the recognition of patients, precisely. Conclusion: The considered patient-based indices did not meet the competencies to define the orthodontic need in the adolescents, but it could be employed to identify the persons with impaired quality of life and it would probably benefit the process of prioritization.

Introduction: Clinical education has a remarkable importance in medical education. Awareness of dentistry students' view from the educational setting, faculty and nurses will help on developing strategies for qualitative and quantitative improvement of clinical training. This study aimed to assess Isfahan Dental School students' satisfaction and views or satisfaction of clinical setting, in order to gain insight about its strengths and weaknesses. Methods: In a cross-sectional study, all of students of Isfahan Dental School in one educational year (1388) were asked to fill a questionnaire with 16 standard questions. The questionnaire was about student's satisfaction from teachers, nurses, equipments and facilities of clinical setting, student's self-steams and satisfaction of their action in clinical practices. The data was analyzed by SPSS software using descriptive statistics, ANOVA and ttest. Results: There was a significant statistically difference between the mean score of satisfaction of different departments. Maximum satisfaction in all components was shown in periodontics and orthodontics departments and minimum satisfaction was shown in endodontic and prosthodontics departments. There was a negative correlation between their satisfactions and their final grades, but this correlation was not statistically significant. Conclusion: Results showed that despite significant differences between satisfaction of different clinical departments, students' satisfaction from different departments is desirable. However, it is suggested to consider in future planning prosthodontics and endodontic departments as a priority. [ABSTRACT FROM AUTHOR]

Objective. To investigate the association between orthodontic treatment need (OTN) and caries experience (CE). Subjects and methods. Using a stratified sampling method, 748 subjects (355 females, 393 males; mean ± standard deviation age 15.11 ± 2.23 years) were examined. The Dental Aesthetic Index (DAI), DMFT, simple (DMFT > 0) and severe CE (DMFT > 8) were recorded. Socio-economic status (SES) was assessed by recording parental education, mother's employment status, and household size. Results. Higher (but not statistically significant) CE was observed in subjects with OTN (DAI > 30). The association between DAI and DMFT scores was not significant (rho = 0.05). Mean DMFT score did not vary significantly between the SES and OTN subgroups. In children with a household size >6 persons ( n = 85), OTN was associated with higher CE and a higher prevalence of severe CE compared with those without OTN. In this group, when DAI treatment need grade increased, severe CE prevalence also increased from 10.8% to 50%. Similarly, in those with OTN and household size >6 persons, the odds of observing subjects with severe CE was 4.6 times higher (95% confidence interval 1.45-14.55) compared to those without OTN. Conclusions. Associations were observed between OTN and CE and also between the prevalence of severe CE and the severity of malocclusion in children with a household size >6 persons. The current findings suggest that the relationship between caries experience and malocclusion should be assessed in a wider context of SES and background factors. [ABSTRACT FROM AUTHOR]

Introduction: The current study aims to study people's access to oral and dental health-care services and their satisfaction with the services provided to them., Materials and Methods: A descriptive study with multi-stage sampling was conducted on 1360 people aged 16-64 years residing in Isfahan city, Iran. The required data were collected by a questionnaire which comprised of three main parts: demographic characteristics, patients' access to oral and dental health-care services and its barriers and participants' satisfaction with access to services. Data were analyzed by SPSS statistical software., Results: The results showed 40% of participants reported an average level for oral health, and 82% of them did not have any problems regarding access to dental care facilities. The main causes of their dissatisfaction were high cost of services (60%) and insufficient health insurance coverage (40%). About 73% reported that they had to spend 30 min or less to access to a dental health-care facility. In addition, 50% of participants were satisfied with the provided services. The main reported reasons for referring to dentists were oral and dental problems (69%) and regular check-ups (15%). There was no significant relationship between participants' gender, education level, insurance coverage, and access to dental health-care centers ( P > 0.05)., Conclusion: Most participants were satisfied with access to dental healthcare, but they were dissatisfied with the costs and inadequate insurance coverage. About half of the participants were satisfied with the services provided to them, and the highest level of satisfaction was reported for easy access to health-care centers., Competing Interests: There are no conflicts of interest.

Background: The aim of this study was systematic review and meta-analysis of prevalence in current and relevant literature about this developmental disorder to present the profile of malocclusion in Iran., Methods: This review study was carried out with systematically identified and critically assessed studies reporting malocclusion prevalence among Iranian population in permanent dentition. National and international databases were searched for articles about prevalence of malocclusion by Angle classification in different regions of Iran from 1994 to 2015. After applying inclusion and exclusion criteria, the quality of articles was checked by professional checklist. Data extraction and meta-analysis was performed. A random-effect model was employed. Publication bias was checked., Results: Of 2768 articles, 21 cases were included. The pooled prevalence of malocclusion was about 87% (95% CI: 78.3-92.2) in Iranian population; however, the prevalence of malocclusion across individual studies varied considerably (ranging from 23.7% to 99.7%). Prevalence of normal occlusion, class I, II and III malocclusion were reported as 13.3% (CI 95%: 7.8-21.7), 50.7% (CI 95%: 42.9-58.4), 21% (CI 95%: 17.5-25.1), 5.5% (CI 95%: 3-10); respectively. Maximum prevalence of malocclusion was in the East of Iran., Conclusion: The results showed a high prevalence of malocclusion in Iranian population. The baseline information could be appropriately utilized for the future planning to meet the orthodontic treatment need among the Iranian population., Competing Interests: Conflicts of interest The authors declare that there is no conflict of interest.

Aim: Evidence-based dentistry (EBD) is an approach to oral health that requires the application and examination of relevant scientific data related to the patient's oral health and his priorities. The aim of this study was to assess knowledge, attitude, and practice of dental students of Isfahan about EBD., Materials and Methods: In this descriptive study, 168 dental students in 3 final years of their education who engaged in clinical practice by consensus sampling were recruited. For data collection, a validated questionnaire was used. The questionnaire was consisted of demographic questions and some questions about four issues: Knowledge of self-assess (KSA), evidence-based practice, actual knowledge and attitude about EBD. Data were analyzed with t-test, one-way ANOVA, Chi-square, and linear regression with SPSS 16., Results: One hundred and thirty-six students from 168 students were filled the questionnaire. The mean of KSA was 13 ± 4.3, mean of usage of useful references in EBD was 16.9 ± 7.6. One-third of students were studied their last article in last 6 months before. The mean of actual knowledge and attitude was 7.4 ± 2.3 and 24 ± 3.8, respectively. The relation between 4 main issues was significant (P < 0.05)., Conclusion: By considering overall interest and positive attitude toward learning EBD in dental students, it is highly recommended that practical educational courses about EBD be planned by dental faculties.

Introduction: Ensuring achievement of research experience by students is one of the most important goals of the thesis-conduction process and evaluation of student satisfaction with this process is one of the most imperative challenges herein., Aims: The aim of this study is to investigate the satisfaction of dental students passing the thesis educational course from the Isfahan Dental School., Settings and Design: Sixty-two dental students who had graduated in2011, from the Isfahan Dental School, participated in this descriptive cross-sectional study., Materials and Methods: The postgraduate Research Experience Questionnaire (PREQ) was used for data collection. The questionnaire evaluated student satisfaction in seven domains: Thesis supervision, skill development, intellectual climate, infrastructure, thesis examination, goals and expectations, and overall satisfaction., Statistical Analysis Used: The data were analyzed on an SPSS software using descriptive and inferential statistics., Results: The mean score of satisfaction of the participants was 75 ± 12. On the basis of their scores, satisfaction in 3.2% of them was slow, in 33.9%was medium, in 61.3% was good and in 1.6% was high. The highest satisfaction was found to be in thesis supervision and the least was in the intellectual climate domain. There was no significant statistical difference between satisfaction and gender (P = 0.46)., Conclusions: Considering the results, to increase student satisfaction for passing the thesis courses, it is necessary to improve the intellectual climate in dental schools and also increase the research budget for more financial support of students to carry out their projects.
