Background:Forensic facial reconstruction is a combination of both artistic skill and scientific methods.It can be used to reconstruct the soft tissues onto the skull in order to obtain the image of an individual for her/his recognition and identification . Some reviewers considered that forensic facial reconstruction is a method of facial approximation, i.e. various facial patterns can be established from the same skull. Main body: The review aimed to describe CBCT is the better investigating tool for the facial recognition for forensic identification A search in PubMed,Google Scholar,and Scopus electronic databases from 2010 to 2020 was conducted to include studies according to PRISMA guidelines.12 studies were eligible for the review. Conclusions: .Cone beam CT images of the face using routine scanning protocols are a reliable method of measuring the soft tissue thickness in the facial region and give a good representation of the facial soft tissues.
Introduction: The creation of technologies using anatomical components like the maxillary sinus and frontal sinus that might preserve their stability yet after extreme events, are helpful for forensic investigations because sex determination is a crucial component of determining the profile of an individual. Aim: To determine the sex using Cone Beam Computed Tomography (CBCT) scans, in a South Indian community by measuring the frontal and maxillary sinuses. Material and Methods: The present cross-sectional study was conducted in the Department of Oral Medicine and Radiology, Sri Balaji Vidyapeeth University, IGIDS, Pondicherry, India, from 1st March 2021 to 31st March 2022. Analysis included 45 CBCT scans from 22 males and 23 females were subjected to volumetric measures in the maxillary sinus and frontal sinus. Applying NNT software, the volume measurement was carried out. The data was used to feed into a sex identification mathematical model. For evaluation, the student’s t-test has been used. Results: In the total study subjects, the mean age of males was 36.909 years and of females was 36.304 years. Only the volume of the frontal sinus varied significantly among males and females (p-value<0.001). The discriminant function analysis equation showed that 50% of males and 91.3% of females correctly identified their gender. According to the crossvalidated categorisation, 71.1% of the people were accurately categorised altogether. Conclusion: Segregation identification, which was validated with evaluations in the frontal and maxillary sinuses with CBCT scans, is another technique for identifying individuals who identify as Indian. The present study shows that paranasal sinus morphologic evaluation is a useful method for identifying a person’s gender.
Objectives This systematic review evaluated whether CBCT is a better diagnostic tool in facial forensic reconstruction. Forensic facial reconstruction is a technique to reconstruct human face from unidentified face from skull remains for human identification and facial recognition. Materials and methods Article selection and data extraction was done based on the inclusion and exclusion criteria devised for the study. The articles were screened from PubMed, ProQuest, Google scholar, Science direct and Scopus. Result Three hundred and thirty-nine articles were initially identified from which seven articles were full text reviewed and included in the review. All the articles included in this study suggest that the facial reconstruction done using CBCT are reliable. Conclusion The computerized 3D modeling method produces reliable facial reconstructions which involves the images scanned from CBCT and the combination method. The computerized 3D modeling method produces facial reconstruction which almost mimics the original resemblance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
