Knowledge of the anatomical relationship between maxillary posterior teeth and the floor of the maxillary sinus is very important for preoperative treatment planning in dentistry. The aim of the study is a comparative evaluation of the relationship and the distances between maxillary posterior teeth root tips and the floor of the maxillary sinus in different cephalic index subjects using a digital orthopantomogram. Materials and Methods: 210 subjects were categorized as Brachycephalic, Mesocephalic and Dolichocephalic according to their cephalic index. Orthopantomograms of these subjects were taken for assessment of vertical relationships between the maxillary posterior teeth and the floor of the maxillary sinus followed by distance measurement. Recorded data were statistically analyzed. Results: Significant difference in vertical distance was observed in all three cephalic groups in the case of 1st premolars, distobuccal roots of 1st molars and mesiobuccal roots of 2nd molars. Conclusion: The study concluded variation in the cephalic index affects the relationship and vertical distance between the maxillary sinus floor and the roots of maxillary posterior teeth.","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":"135641455","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}

One such method is the indirect assessment of quantified secondary dentinal deposition through measurements of tooth and pulp. Kvaal, et al., developed a method for chronological age estimation based on pulp size using periapical dental radiographs. There is a need to test this method of age estimation in the Indian population on living individuals not requiring tooth extraction. The current study aimed to assess the applicability of Kvaal’s method in maxillary permanent central incisor using CBCT. Materials and Methods: The study included 185 CBCT images of the individuals, ranging in age from 14 to 64 years. CBCT images were evaluated for the maxillary central incisor and metric measurements were taken from which ratios were derived. Using the ratios, a linear regression equation was derived, from which the age of an individual was predicted. Result and Conclusion: The correlation between the individual ratio and the chronological age was calculated using the Pearson correlation coefficient. The age of the individual was predicted using a linear regression equation with a SEE ranging from 10.05 to 12.78 years. When the samples were divided into various age groups, the Standard Error of Estimate has drastically reduced. The radiographic pulpal morphometric analysis used in present study can be recommended to assess the age of an adult for forensic purposes.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"16 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":"135642471","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}

Knowledge of the position of the mental foramen is important both when administering regional anaesthesia and performing periapical surgery in the mental region of the mandible. Aim: The aim of this study was to determine the position and symmetry of the mental foramen on a digital orthopantomogram (OPG) among the Nalgonda population. Materials and Methods: A total of 400 digital OPGs taken by the Rotograph evo OPG machine of both genders were analysed retrospectively. The position of the mental foramen was recorded according to criteria given by Wei Cheong Ngeow and Yosuf Yuzawati. The symmetrical or asymmetrical position of the mental foramen was also recorded. Results: The most common position in the current study for the right side was position 4 (n = 202; 50.5%) followed by position 3 (n = 102; 25.5%), position 5 (n = 82; 20.5%), position 2 (n = 8; 2%), position 1 (n = 4; 1%) and the least common was position 6 (n = 2; 0.5%) and the most common position of mental foramen for left side was position 4 (200;50%) followed by position 3 (n = 132; 33%) , position 5 (n = 60; 15%), position 1 and 2 (n = 4; 1%) and the least common was position 6 (n = 0; 0%). The mental foramen was symmetrical in 250 patients (62.5%) and asymmetrical in 150 patients (37.5%). For the symmetrically placed mental foramina, the most common location was position 4 (n = 126; 50.4%) followed by position 3 (n = 76; 30.4%), position 5 (n = 42; 16.8), position 6 (n = 4; 1.6%), position 2 (n = 2; 0.8%), position 1 (n = 0; 0%). Conclusion: In the present study, it was found that the most common position of the mental foramen in the given population in both males and females was below the second premolar, followed by between two premolars. It was symmetrical in 62.5% of OPG’s. The current study was limited to evaluating the position and symmetry of the mental foramen relative to mandibular teeth in a small sample of the Nalgonda population in Telangana state using digital panoramic radiographs. In further studies, utilizing a larger sample size for evaluation of the mental foramen using advanced imaging modalities would be required for a more precise identification of the mental foramen.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"96 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":"135642731","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: A cross-sectional study was carried out among patients of either gender visiting the outpatient Department of Oral Medicine and Radiology, of Ahmedabad Dental College and Hospital. A sample size of 100 subjects was decided and was divided into three groups: Group 1: 50 subjects with habit of eating betel nuts and OSMF. Group 2: 25 subjects with habit of eating betel nuts without OSMF. Group 3: 25 subjects without a habit of betel nuts chewing and not having OSMF. The ink was uniformly applied over the fingers by using a stamp pad. Prints of fingertips were taken. Results: On comparing the dermatoglyphic patterns with subjects of groups 1, 2 and 3, OSMF subjects had an increase in simple whorl patterns and a decrease in arch patterns, and subjects with a habit of betel nut chewing without OSMF had an increase in ulnar and radial loop patterns. Conclusion: The present study was undertaken to observe and compare the dermatoglyphic patterns in betel nut chewers with and without oral submucous fibrosis. On digit vise comparison of the finger ridge patterns of both hands, the middle finger and ring finger of the right hand showed statistically significant p values. Thus, with the help of these parameters, gutkha chewers likely to develop OSMF can be detected earlier and the cost burden associated with genetic cytomarkers may also be prevented.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"35 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":"135641589","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}

Dental age estimation by RDT has been tested on different geographic groups in order to determine its applicability and it has been found that there was an under/overestimation of the age of the subjects in different populations. No systematic review of these studies has yet been published to check the reliability and accuracy of this novel method in estimating chronological age. Objective: To assess the accuracy and reliability of RDT-based dental age estimation in different academic and forensic scenarios by qualitatively summarising the results of RDT-based dental age estimation studies in diverse population samples. Evidence Review: Studies were searched in the Medline, Embase, Directory of open access journals, Cochrane library and Google Scholar databases up to December 2019 with previously defined inclusion and exclusion criteria. The outcome of interest was the difference between chronological age and the age estimated from RDT. Results and Conclusion: A total of 1754 subjects from 16 published studies were included in the final review. Our findings proved that the RDT method tends to overestimate chronological age for both sexes in most of the study population. The overestimated dental age ranges from 2.24 to 15.1 years.","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":"135642176","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}

Human identification is one of the most challenging tasks in this process. However, when a victim is edentulous, methods for personal identification available in forensic odontology are much more limited than in the case of dentate victims. In such cases, additional/supplemental aids like palatal rugoscopy hold promise. Materials and Methods: Two hundred subjects were included in the study, they were divided into 4 groups, each of the four groups included 50 participants, consisting of 25 males and 25 females. Maxillary impression was made for all the included subjects and casts were poured and analysed. Results: A total of 2104 palatal rugae were observed in 200 subjects. When types of rugae based on length were compared between males and females on each side of the palate, primary type, secondary type and fragmentary type were observed in a mean number of 4.19, 0.78 & 0.18 in males and 4.20, 0.81 and 0.16 in females respectively on the right side. Whereas on the left side, primary type, secondary type and fragmentary type were found in a mean number of 4.59, 0.83 & 0.09 in males and 4.40, 0.78 & 0.07 in females respectively. Conclusion: It may be concluded that the rugae pattern may be an additional method of differentiation, which may help narrow the process for identification and give results in conjunction with other methods such as finger prints and dental characteristics in forensic sciences. Palatal rugoscopy may thus be used successfully as an adjunct in the process of forensic identification.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"41 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":"135642521","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}
