Aims: Assessment of gender using mandible with Cone Beam Computed Tomography (CBCT). Settings and Design: This cross-sectional prospective study was conducted on dental outpatients in the department of Oral Medicine and Radiology. Methods and Material: 148 dental outpatients were selected and subjected to CBCT. Mandibular landmarks such as gonial angle, alveolar ridge to mental foramen distance, mental foramen to the inferior border of mandible distance, mandibular canal to the most anterior tangent point of buccal and lingual mandibular plate distance, mandibular canal border to the lowest tangent point on the inferior border of the mandible, coronoid height, bigonial breadth, minimal ramus breadth and ramus length were assessed on CBCT scan. Statistical Analysis Used: Data was represented as mean and Standard Deviation (SD). Parameters were compared between males and females using Kruskal-Wallis and Student’s independent T-test. A value below 0.05 represented significant results. Results: All parameters except gonial were significantly higher in males as compared to females angle (P< 0.05). The distance from the lowest point of the mandibular canal to the most posterior tangent point of the Mandibular Lingual Plate (MCLM) and bigonial breadth was higher in males than females but the difference was non-significant (P>0.05). The accuracy of CBCT was found to be 89.7% in males and 88.5% in females. Conclusions: Gender determination by morphometric analysis of the mandible using cone beam computed tomography is an effective method and provides higher accuracy as compared to two-dimensional conventional radiographs.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135642568","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}

Estimating the age of children abandoned due to HIV is crucial for forensic records. The present study aimed to compare HIV-infected children with healthy controls in terms of dental age using the Willems method. Methods: The study sample consisted of orthopantomograms of 40 HIV patients aged 5-16 years and 50 children aged 6-16 years as the control group. The HIV group included children with vertical infections who had received antiretroviral therapy. The Willems method was used to compare two groups in terms of dental age. Results: Dental age estimation in both HIV and control groups was overestimated using the Willems method. Nevertheless, the overestimation rate was approximately one month in the control group and less than two months in the HIV group, making the method widely applicable for estimating dental age in both healthy children and HIV patients. The dental age of the HIV-infected children was lower than that of the control group. Conclusion: This study indicated a lower dental age in the HIV-infected children compared to the control group. The results demonstrated that dental age estimation using Willems method closely approximated the chronological age of HIV patients.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135642657","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}

The goal of this study was to comparatively evaluate the accuracy of overlays made with a digital, two-dimensional method compared to those made by directly tracing bite marks and using bite mark images obtained with a photocopier. Materials and Methods: A total of 61 participants were included in the study, of whom 31 were males with ages ranging between 18-65 years and 30 were females. The simulated bitemarks on the cheese block were used to prepare three sets of overlays, first by the way of hand-tracing, followed by a photocopying technique and a third set of overlays prepared using computer software called Adobe Photoshop version CS6 on a personal computer. Each pair of overlays and the study cast was then matched using 5-point criteria given by the ABFO guidelines, and a score between 0-3 was assigned to each observation. Results: The overall scores obtained in each group (A-hand-tracing, B-photocopy, C-digital method) were then compared amongst themselves for associations. By applying the Kruskal Wallis ANOVA test, the manual technique had a 29.5% positive matching rate, in photocopying method 32.8%, and the digital overlay 72.1%, which was significant. Conclusion: In conclusion, the digital overlay method outperformed the hand-tracing and photocopying methods in terms of minimizing the subjective errors and was found to be the most precise and dependable method.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135641836","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}

Materials and Methods: The study group comprised 150 healthy adults of either gender over the age of 20 years. One paranasal sinus radiograph was made for each patient using the standardized radiographic technique. Digital measurements of the height, width and area of the frontal sinuses were recorded using AutoCAD 2014 software. The data collected was subjected to statistical analysis. Results: This study found an accuracy rate of 68.6% for sex determination through paranasal sinus radiographs. It was noted that the right height of the frontal sinus was a better predictor than any other parameter assessed for identifying the gender. Conclusion: From the present study, we conclude that the dimensions of frontal sinuses on PNS views can be used as an essential tool for gender determination in forensic sciences.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135642539","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}

However, studies involving paediatric age groups are scarce. Aims and Objectives: To evaluate the volumes of maxillary and frontal sinuses in children aged 9–14 years of age and establish a correlation, if any, between the volumes and the age and sex of the children. Settings and Design: A retrospective study. Materials and Methods: Volumetric measurements of the maxillary and frontal sinuses were conducted on CBCT scans of 30 children aged 9-14 years, divided into three groups, those aged 9–10 years in group A, 11-12 years in group B, and 13-14 years in group C. Statistical Analysis Used: One way ANOVA test to compare the sinus volumes within the groups and unpaired t-test to compare the difference in the volumes in males and females as well as between right and left maxillary sinuses were used. Results: The mean values of the volumes of the right and left maxillary, total maxillary, and frontal sinuses in Group A were 8.4940±1.1966 cm3, 8.3774±1.2047 cm3, 16.8714±2.1212 cm3, and 2.1903±0.8870 cm3; in Group B were 8.7553±0.9067 cm3, 8.3937±1.1461 cm3, 17.1490±1.5732 cm3, and 3.0469±1.5907 cm3; and in Group C were 11.9895±2.230 cm3, 12.6164±1.6797 cm3, 24.6059±4.38536 cm3, and 7.6546±1.7763 cm3, respectively. The difference in the values among all three age groups was statistically significant (p < 0.001). However, there was no significant difference in the values between males and females or between the right and left maxillary sinuses.

Aim: This study explored the practices and perceptions of the health professionals working with the police towards age estimation for juveniles undergoing criminal proceedings in Uganda. Methods: It was a qualitative study using key informant interviews. Seventeen health professionals working in private clinics and general government hospitals linked to the police were purposively selected. Data were collected using a key informant interview, which allowed the participants to express their views and perceptions concerning the different aspects of the age estimation process. The information gathered focused on the methods used to estimate age and their appropriateness, particularly based on the third molar eruption. The data were analysed using thematic content analysis methodology. Results: It was found that the current practice of age estimation in the country does not fully adapt to international standards and that there are variations among the users.

Among all the bones in the human body, the pelvis and the skull show the maximum sexual dimorphism. But in cases where an intact skull is not found, the mandible becomes our first choice for gender determination, as it is covered with dense, compact bone, which makes it very durable and well-preserved. Aims and Objectives: To determine the effectiveness of condylar height, coronoid height and gonial angle of the mandible for sex determination using orthopantomography and to compare and determine the most reliable parameter for gender determination. Materials and Method: This study was conducted using digital panoramic images of 25 patients of each gender. The images captured were viewed on AutoCAD 2014 software and were subjected to measurements of the condylar, coronoid heights and gonial angles both on the left and right side using AutoCAD 2014 imaging software. The data was entered into a Microsoft Excel sheet and statistical analysis was done. Results: The Student t-test showed significant (P < 0.05) differences and higher values for both condylar height and coronoid height on both the right and left sides of males as compared to females. However, the difference in the mean gonial angle on both the right and left sides did not differ (P > 0.05) between the two genders. All three variables were higher in males as compared to females. Conclusion: The parameters such as condylar height, coronoid height and gonial angle using orthopantomographs are reliable in gender determination and the condylar height of the left side is the best parameter in gender determination.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"300 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135641975","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}

Materials and Methods: We conducted a descriptive transversal survey of students in the 4th year of the academic year 2015/2016 at the Faculty of Dental Medicine of Casablanca. The study is made on plaster models for students, by measuring the mesiodistal diameter of the TC with an electronic calliper. Results: Several results were obtained: 64.29% of the study population have CT, while it is absent in 35.71% of cases, 37.50% with a tubercle of Carabelli little developed, 26.71% with a well-developed Carabelli tubercle, 61.11% of cases exhibit TC bilaterally and 38.89% of cases present the TC unilaterally. The results are consistent with those obtained in other surveys conducted in other countries and discordance with others. Conclusion: The lack of standardization of the study’s methodology makes it difficult to compare the results of various studies, hence the need for similar studies on larger samples. It has some importance in the dental, forensic, and anthropological fields. In orthodontics, the cause of premature caries and periodontal diseases, also in extractions, the molar extraction instruments have no housing for this cusp and can therefore lead to fracture.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135643102","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}
