“…Focusing on forensic medicine, it is possible to notice that since 10 years ago, CBCT was used with different purposes, such as, for example, in forensic identification through facial soft tissues thickness measurement and craniofacial reconstruction, and frontal sinus, mandibular lingual canals or teeth superimposition; for bite marks analysis; for sex determination identifying a possible dimorphism of the mandibular body, the foramen magnum, and the maxillary of frontal sinus; and of course for age estimation [43][44][45][46][47][48][49][50][51][52][53][54].…”

The age of a living human being can be determined by applying a number of different methods; the most diffused are skeletal and dental methods, both principally based on X-rays examinations. This systematic review assesses the current evidence regarding the accuracy and reliability of Cone Beam Computed Tomography (CBCT) vs. Orthopantomography (OPG) in age determination. A computerized systematic literature search of studies published up to January 2020 was conducted without language restrictions in order to identify articles comparing CBCT vs. OPG in dental anatomy evaluation, articles evaluating the accuracy of dental methods for age estimation, both with CT and OPG exams, and articles comparing CBCT vs. OPG in terms of radiation dose. CBCT was found to be more accurate compared to OPG in dental anatomy evaluation. When analyzing young adults, an estimation error of two years is considered forensically acceptable. The radiation dose of a CBCT exam is higher compared to an OPG exam. However, the difference is not as marked with small Fields Of View (FOV) and low-resolution protocols. Final conclusion was that a small FOV CBCT centered on the mandibular angle of a young patient is an accurate and safe method for dental age estimation around the age of 18.

“…Автору також вдалось виявити і протилежний зв'язок: у 48% випадків при проведенні автопсії були зареєстровані такі значимі ідентифікаційні ознаки, котрі не були відмічені на отриманих томографічних зрізах. Незважаючи на це, багатьма авторами було висунуто припущення, що томографічні методи дослідження залишаються на разі єдиними у структурі комплексної судово-медичної оцінки, які забезпечують можливості для автоматичної реєстрації усіх змін організму, що в подальшому можуть бути проаналізовані, виключивши вплив декомпозиції окремих анатомічних структур [1,2,6,9,10]. Крім того, отримані цифрові дані можуть бути опрацьовані із використанням різного доступного програмного забезпечення, що відкриває нові можливості для судово-медичної експертизи жертв масових катастроф.…”

Background: Cone-Beam Computer Tomography (CBCT) is a non-invasive, rapid, cost-effective, and low-radiation technique. Being a three-dimensional (3D) imaging process, it is better suited for the analysis of 3D structures like teeth, bones, or facial sinuses. CBCT is already widely used in dentistry and its application in forensic odontology is promising. Objective: This study aimed to provide an overview of CBCT use in forensic dentistry. Method: A bibliographic search using PUBMED was performed with the following keyword combinations: ("Cone-Beam Computed Tomography"[MeSH Terms]) OR (cbct)) AND (forensic dentistry) OR ("Forensic Dentistry"[Mesh]) and on the Scopus platform using the keywords “cbct forensic dentistry”. Considering the inclusion and exclusion criteria, the final selection resulted in 68 studies. Results: Articles subjects were as follows: 11 studies (16%) on comparative identification, 4 (5%) on identification by bitemarks, 30 (44%) on age estimation, 20 (29%) on sex estimation, and 7 (10%) on facial reconstruction. CBCT technology proved to be an accurate tool for age estimation (particularly in the pulp narrowing technique), sex estimation, bitemarks analysis, and facial reconstruction. Conclusion: CBCT's increasing use in dental clinics makes a huge quantity of data available. Professionals should examine how to organize and disseminate these valuable antemortem data. Training is mandatory to understand CBCT’s technical limitations as well as manage the presence of artifacts. Further studies should be made on larger samples to fully understand the potential of CBCT technology in forensics.
