However, Group C had a significantly lower MMO compared to Groups A and B after 90 days (P=0.001). Additionally, and in relation to masticatory muscle pain, Group C had a significantly higher VAS score than other groups (P<0.05).

All the data including etiology, gender, age, ethnicity, year and place of occurrence, and site of fracture were obtained from the medical records of all oral and maxillofacial trauma patients who were subjected to ZMC fracture. Chi-Square and Fisher’s exact tests were used to analyze the data. Results: Mean age of the patients was 29.53±14.13 years. Out of 187 patients, 87.2% (163 people) were male and 12.8% (24 people) were female. People between 20 and 40 years had more ZMC fractures than other age groups with 104 cases (55.7%). Baluch ethnic group with 111 people (59.3%) experienced more fractures than other ethnic groups. The highest fracture rate occurred in 2021 with 63 cases (33.7%). Street was the most prevalent place of occurrence for fractures with 134 cases (71.6%). Isolated cheek fracture was the most common with 95 cases (51%). The most common cause of fracture was traffic accidents with a prevalence of 71.1%. Conclusion: The results revealed that traffic accident is the main cause of ZMC fractures in the studied population. Thus, public awareness and strict implementation of traffic policies are needed.","PeriodicalId":52622,"journal":{"name":"Journal of Craniomaxillofacial Research","volume":"25 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135037179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, many general dentistry graduates seldom practice orthodontics. This study assesses the desire of last-year dental students at Shahid Beheshti Dental School towards orthodontic treatments in their future career. Materials and Methods: A questionnaire was validated by ten dental specialists. For reliability, it was re-administered to ten students after ten days. Descriptive statistics were used for results presentation. The Mann-Whitney test compared ranked responses, and the Kruskal-Wallis test compared grade point average (GPA) variations. The comparison of mean opinions based on age, gender, and academic term was conducted with the t-test independent samples and based on GPA status with a one-way ANOVA. Analyses were done using SPSS 25, with a significance level of 0.05. Results: In this study, 58 last-year students were questioned in line with the research objectives. More than half of the students believe that the hours dedicated to teaching orthodontic courses at university are insufficient (65%), the quality of theoretical teaching is low (55%), practical teaching hours and presence in the department are inadequate (48%). Only 15 percent of students declared they have the necessary confidence to diagnose and conduct orthodontic treatments after graduation. About half of the students express an interest in attending supplementary orthodontics courses after graduation (39%). Conclusion: According to approximately half of the students’ opinions, the quality of teaching theoretical and conceptual orthodontics courses is low. Additionally, students lack the necessary confidence and desire to diagnose, plan, and perform treatments after graduation.","PeriodicalId":52622,"journal":{"name":"Journal of Craniomaxillofacial Research","volume":"36 38","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135038509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to compare panoramic radiomorphometric indices between dentate and totally edentulous patients. Materials and Methods: One hundred panoramic radiographs were analyzed to measure six indices using Clinview 9.3 software: the gonial angle (GA), antegonial angle (AGA), condylar height (CH), ramus height (RH), mental index (MI), and mandibular cortical index (MCI). An independent sample t-test and Chi-square was used to compare the means of the measured data between dentate and edentate subjects and genders. Results: In both genders, dentate people had greater left CH (p=0.05) and left GA (p=0.03). Men had greater RH in the dentate and edentate groups (p<0.001). No correlation was found between groups and genders in MCI scores.  Conclusion: CH index assessment as the function of the masticatory muscles and GA as residual ridge resorption were decreased in edentulous people.

The proximity of maxillofacial skeleton to important sensory or vital structures such as the visual, olfactory, masticatory and respiratory systems and intracranial components in addition to negative effects on esthetic aspects of the face have doubled the intricacy. Small or thin fractured segments that are difficult to find and stabilize make management of pan facial fractures different from anywhere else in the body. One major challenge is to find the best pattern and sequence of treatment. There are different concepts, depending on the surgeon's experience and the pattern of fracture. This study reports three patients with the diagnosis of pan facial fractures.

It was diagnosed on more than 377,700 cases worldwide in 2020. Access to high-quality care leading to a more specific and earlier diagnosis of this cancer is crucial. Therefore, researchers attempt to investigate and detect efficient biological tumor marker. The present study aimed to investigate the changes in the expressions of miR-182, miR-221, and carcinoembryonic antigen (CEA) in the peripheral blood of patients with oral squamous cell carcinoma (OSCC) and compare them with healthy individuals to detect early OSCC. Materials and Methods:30 peripheral blood samples from patients with OSCC (19 male and 11 female), aged 25-70, were obtained from the cancer institute of Tehran University of Medical Sciences, and 30 peripheral blood samples from healthy individuals (20 male and 10 female) aged 26-70 were collected. Real-time PCR was carried out to investigate the differences in the expressions of miR-182, miR-221, and ELISA was used to measure CEA protein expression. Results: Among the subjects with OSCC 83% showed miR-182 expression, 93% revealed miR-221 expression and 96% demonstrated CEA expression. Whereas, these expressions were 26%, 20% and 13%, respectively, for the healthy group. The simultaneous detection of miR-182 and miR-221 was 73% in the individuals with OSCC. The simultaneous observation of miR-182, miR-221, and CEA in the group with OSCC was 60%. The expression level of miR-221 in the group with OSCC was 2.63 times that of the healthy subjects, and the expression level of miR-182 in the individuals with OSCC was 2.29 times that of the healthy group. Conclusion: The results of this study nominated miR-182, miR-221, and CEA as biomarkers for early diagnosis and consequently improvement of survival rate of patients suffering from OSCC.","PeriodicalId":52622,"journal":{"name":"Journal of Craniomaxillofacial Research","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135817057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
