It can serve as an important tool in forensic identification particularly when other regular methods of identification become difficult.Aim: To evaluate the palatal rugae pattern between both gender in terms of Number, Shapes and Length on right and left sides among different age groups.Materials and methods: Cross-sectional study comprising of 60 patients which were divided into four groups according to their age. Each of the four groups consisted of 15 participants of whom 30 were males and 30 were females. All the patients meeting the inclusion and exclusion criteria were randomly selected and alginate impressions of the hard palate were taken and casted by dental stone. The data were assessed based on the Thomas and Kotze classification (1983) and the rugae patterns were delineated using sharp graphite pencil under adequate light and were analysed macroscopically.Statistical analysis: The obtained values were analysed using Student’s t- test for evaluation of gender difference in rugae patterns and ANOVA was applied for determination of age groups using SPSS version 20.0 software.Results: Palatal rugae of right side showed higher prevalence and curved rugae in females than in males and the finding is statistically significant. The mean number of rugae showed a slight decreasing trend with increasing age with more curved rugae and size of the palatal rugae is slightly increased up till the middle age group, as growth ceases thereafter.Conclusion: The present study reveals significant gender and age difference in palatal rugae pattern. Thus, palatal rugae appear to possess features of an ideal forensic identification parameters such as uniqueness, postmortem resistance and stability, provided antemortem record exists.","PeriodicalId":426743,"journal":{"name":"International Journal of Forensic Odontology","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121651723","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 study subjects was divided into group I and group II consisting of 15 females and 15 males in each group respectively following obtainment of informed consent. All the buccal mucosal smears were processed accordingly as described by Ayyad S B et al (2012), Meena N et al (2016) and Wadsworth A et al (2012) for May Grunwald-Giemsa stain, Carbol fuchsin stain and Van Geison stain. The barr bodies identification was determined by the presence of a darkly stained condensed area on the nucleoplasm as described by Balderman S et al.RESULTS: The results thus obtained showed that CF had a better BBI compared to MGG and VG and the statistical analysis showed 100% specificity, sensitivity and reliability in all the three stains in identifying barr bodies. Barr body was found to be negative in the male samples and positive for female samples with Carbol fuschin yielding 9.8% of Bar Body Index (BBI), May Grunwald-Giemsa yielding 5.4% and Van Geison yielding 2.8%.CONCLUSION: On comparison, the efficacy and accuracy for detection of Barr bodies were more with Carbol fuschin following May Grunwald-Giemsa and Van Geison.","PeriodicalId":426743,"journal":{"name":"International Journal of Forensic Odontology","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134313344","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}

In addition to gender, age is an essential basic biological parameter which facilitates the identification of human remains in forensic and palaeodemographic contexts. It is also well established that the use of morphological characteristics of the teeth is considered to help more reliable age estimates than most of the other methods as the teeth are sometimes the only skeletal remains to be used for the estimation of age if the skeletons are highly damaged. Aim: The aim of the present study is to propose a method for assessing the chronological age based on the relationship between age and measurement of pulp/tooth area ratio (AR) on canine teeth using digital orthopantomographs for a Sri Lankan population. Materials and Methods: The sample consisted of orthopantomographs (OPGs) of 231 subjects (113 males and 118 females) aged 17–76 years. The AR of upper and lower canines was calculated according to the reported technique, and statistical analysis was performed to obtain multiple regression formulae for dental age calculation, with chronological age as the dependent variable, and gender, left and right side of upper and lower canines as independent variables. Results: The AR between right and left canine teeth of maxilla and mandible shows no statistically significant difference and also no significant effect of gender on all regression models. Furthermore, as the intercept and slope of all regression equations show highly significant consistency in predicting the chronological age any permanent canine tooth of the dentition can be used with high reliability for the estimation of age. Mean prediction errors of the present study were 0.16 years and 0.21 years, respectively, for right and left mandibular canines and 0.10 years and 0.15 years, respectively, for right and left maxillary canines and confirms the high reliability and accuracy in the prediction of age. Conclusion: The result of the present study shows that estimating the age using the formulae is highly reliable and accurate, and intercept and slope of the formulae are different in each population group.","PeriodicalId":426743,"journal":{"name":"International Journal of Forensic Odontology","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128208064","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}
