In some scenarios, individual identification gets masked by chimera persons, where the chimera person cells will have different DNA. The use of biological traces which are recorded by a person’s touch while handling items raises the chance of forensic study system. Therefore, DNA profiling can be obtained from items that were touched, which inturn becomes an useful means for forensic mode of investigation. Chimerism investigations are recognized processes to examine the condition of Hematopoietic Stem Cell Transplantation (HSCT) to analyze peripheral blood and recipient’s bone marrow samples for non-malignant and malignant hematologic diseases. In adults, ectomesenchymal cells identified in oral and maxillofacial tissues are promising for future dental stem cell therapies, because the oral tissues area rich source for stem cells. Dental stem cells have various expressive profiles and exist in specific niches. Apart from these applications, this review article highlights dental stem cells significances in forensic dental investigations.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"211 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80652736","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}

Methods: The present study included 600 subjects. 200 from each population were selected randomly and examined for dental anomalies and their dermatoglyphic patterns were recorded. Statistical Analysis Used: The study was analyzed by a chi-square test. Results: One dental anomaly was consistently noted in all three populations. Out of 600 subjects, 40.8% had positional anomalies. Shoveling, congenitally missing teeth, and winging were seen significantly in North-Eastern (23.0%), Jammu & Kashmir (5%), and Western Uttar Pradesh (6%) population groups in order. The most common dermatoglyphic pattern seen in all three populations was an ulnar loop. Significant relation between shoveling and whorl pattern was seen in the North-Eastern population. The presence of rotation was significantly more among subjects with a whorl pattern. Conclusion: The study concluded that dermatoglyphics can be used as an indicator of few dental anomalies. It can help in identifying the gender, race of an unidentified person, and various diseases which are correlated with dental anomalies that can be detected earlier.","PeriodicalId":89172,"journal":{"name":"Journal of forensic dental sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87943444","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}

Bilateral maxillary lateral incisors and mandibular left central incisor were significantly small in size for Class III. Square arch form was found more commonly in Class III and ovoid arch form in Class I and Class II occlusion. Intercanine width was insignificant among all occlusions. All the angles of the odontometric triangle in the maxillary and mandibular arches were significant for Class III.Conclusion: Class III occlusion individuals were distinct for shape of the arch and angles of maxillary and mandibular odontometric triangle.

Sanger sequencing was used to determine the genetic sequence of the gene of interest postamplification. Nucleotide base sequence for NPTX2 gene was obtained for each case using this protocol.Subjects and methods: The study was conducted on buccal scrapes obtained from 26 subjects of both genders, whose age varied from 1 to 65 years. The samples, collected by wooden spatulas, were placed in cell suspension buffer and stored at 4°C until transported to the laboratory.Results: Methylation levels of 5'-C-phosphate-G-3' located in the gene NPTX2 of 26 subjects were studied and analyzed by bisulfate sequencing. The percentage of methylation in this study falls in the range between 15% and 51%.Conclusion: In this study, a sufficient amount of gDNA was retrieved from the buccal cells, thus confirming that buccal scrape was a feasible technique to obtain ample DNA.

The aim of study is comparative evaluation and assessment of applicability of Demirjian's method, Willem's method of dental age (DA) estimation, and Maria de Paula Caldas's method of skeletal age estimation for children aged 9-16 years.Materials and methods: A total of 140 individuals (70 females and 70 males) between the age group of 9-16 years were enrolled. These individuals were grouped by a difference of 1 year into 7 groups (each group comprising of 20 individuals: 10 males and 10 females). Dental age estimation was performed from orthopantomograph images of mandibular teeth of left quadrant by both Demirjian's and Willem's methods. Skeletal age estimation was done from Lateral Cephalogram by Caldas Digital Method. The differences between the chronological age and the estimated dental and skeletal ages were statistically tested using paired t-test.Results: Demirjian's DA estimation overestimated males (0.4040 years) and females (0.1316 years). Willem's DA estimation method underestimated males (0.1386 years) and females (0.4210 years) and Caldas skeletal age estimation overestimated males (0.2982 years) and females (0.4259 years).Conclusion: The study concluded Willem's DA estimation method was the most accurate for male and Demirjian's method for female for Gujarati Population.
