“…With the exception of few studies 7,16,21,25 , the majority used completely erupted teeth, with fully formed root, without disease, caries, fracture, restorations nor root canal treatment, because pathological reasons and dental interventions can form a type of dentin 23 that is indistinguishable from secondary dentine in imaging scans. About the sample, when one proposes to determine a method in a population level, a considerable sample amount is expected, and the more expressive number were in the studies of Kazmi et al 4 , Zhan et al 32 and Gulsahi et al 5 .…”

“…The images analyzed in most of the studies were from university/hospital archives or private dental clinics, the tooth being evaluated in situ, in other words, still present in living patients [2][3][4][5][6][7]15,16,[18][19][20][21][22][23]26,28,31,32 . A smaller number of studies used extracted teeth 1,14,17,25,27,29,30 , managing to achieve individual tooth image, and the study of Sakuma et al 24 stands out to use computed tomography took before forensic autopsy.…”

“…The cone-beam computed tomography (CBCT) was the 3D image most used [1][2][3][4][5][6][7]15,16,[18][19][20][21][22][23]26,28,[30][31][32] , followed by micro-computed tomography (Micro-CT) 14,17,25,27,29 and multidetector computed tomography (MDCT) 24 .…”

“…The Micro-CT although provides better resolutions than CBCT and MDCT, increasing accuracy in detection of the boundaries between pulp and hard tissue 14,17,27 , is unpractical in examining living individuals because the tooth extraction or jaw dissection is often required because of the limited scanning area 17,24,32 .…”

Assessment of secondary dentin apposition is an observable phenomenon widely used to estimate age. An integrative review was performed by searching the keywords "computed tomography AND age estimation AND pulp tooth volume ratio" and "microfocus x-ray AND age estimation AND pulp tooth volume ratio" in the electronic platforms Embase, PubMed, Scopus and Web of Science, in July 2020. Studies included: complete articles with age estimation from human teeth by use of computed tomography or micro-computed tomography, written in English, without time restriction. Excluded studies: not written in English or not in form of an article, clinical cases, literature reviews, if did not realize age estimations or if age estimation is done in animals teeth. The search resulted in 32 different articles. With application of the above criteria only 26 were reviewed. Data collected included: reference, year, country, tooth type, number of subjects, number of teeth, age group, image type, measuring instrument/software, type of analysis, coefficient of determination, correlation coefficient with age and accuracy. These data provided a quick global comparison of various methodologies that use the pulp/tooth relation, being practical for researchers and forensic team to which method they can use accordingly to a specific case and its expected accuracy.

Dental radiographies have been used for many decades for estimating the chronological age, with a view to forensic identification, migration flow control, or assessment of dental development, among others. This study aims to analyse the current application of chronological age estimation methods from dental X-ray images in the last 6 years, involving a search for works in the Scopus and PubMed databases. Exclusion criteria were applied to discard off-topic studies and experiments which are not compliant with a minimum quality standard. The studies were grouped according to the applied methodology, the estimation target, and the age cohort used to evaluate the estimation performance. A set of performance metrics was used to ensure good comparability between the different proposed methodologies. A total of 613 unique studies were retrieved, of which 286 were selected according to the inclusion criteria. Notable tendencies to overestimation and underestimation were observed in some manual approaches for numeric age estimation, being especially notable in the case of Demirjian (overestimation) and Cameriere (underestimation). On the other hand, the automatic approaches based on deep learning techniques are scarcer, with only 17 studies published in this regard, but they showed a more balanced behaviour, with no tendency to overestimation or underestimation. From the analysis of the results, it can be concluded that traditional methods have been evaluated in a wide variety of population samples, ensuring good applicability in different ethnicities. On the other hand, fully automated methods were a turning point in terms of performance, cost, and adaptability to new populations.
