“…A radiograph was easier to prepare than ground sections; moreover, radiography could be applied to living humans without extracting the teeth, allowing greater number of samples to be obtained. Therefore, numerous studies have been conducted to date modifying or testing the dental radiograph-based age-estimation methods (Kvaal et al, 1995;Drusini et al, 1997;Kolltveit et al, 1998;Willems et al, 2002;Bosmans et al, 2005;Paewinsky et al, 2005;Cameriere et al, 2007;Meinl et al, 2007;Drusini, 2008;Landa et al, 2009;Du et al, 2011;Cameriere et al, 2013). Meanwhile, with the development of computed tomography (CT) technology, the pulp cavity and the tooth can now be measured in three-dimensional space (Vandevoort et al, 2004;Yang et al, 2006;Someda et al, 2009;Aboshi et al, 2010;Agematsu et al, 2010;Star et al, 2011).…”

Pulp volume decreases throughout life owing to secondary dentin deposition. Here, we present a Bayesian approach for human age estimation on the basis of the pulp volume ratio from lower-canine teeth. We measured the pulp and tooth volumes of 363 subjects (209 males, 154 females) of known age based on three-dimensional imageries from microcomputed tomography scans. Pulp volume ratio was defined as pulp/tooth volume within the root portion (PVRrt) and its reduction with age was modeled by simple statistical assumptions to produce a likelihood function of PVRrt by fitting the model to the observed data. Following Bayes' theorem, we obtained the probability density function (PDF) of estimated age for a given PVRrt, for males, females, and gender unknowns; we used the modern Japanese population as of 2012 as prior age distribution. The PDF of estimated age provided the mean and 50%, 70%, and 90% prediction intervals, based on which we compared the present ageestimation method with that of Brooks and Suchey (Human Evolution, 5: 227-238), which is based on pubic symphysis metamorphosis. We could not find any advantages of the PVRrt method compared to the Suchey-Brooks method for the case of males or gender unknowns as far as the prediction intervals were concerned. However, for females, the PVRrt method offered comparable precision to the SucheyBrooks method. Taking into account other advantages such as sustainability of the material and continuous property of the age-indicator value, we conclude that the PVRrt method is useful in forensic cases, especially those involving female victims.

Objetivo: Determinar la eficiencia del método de estimación de la edad basada en el índice coronal dentario. Materiales y método: Se realizó el método de índice de la cavidad coronal pulpar en 432 piezas dentarias del cuarto cuadrante mandibular (primera premolar=129, segunda premolar=104, primera molar=113 y segunda molar=86), evaluadas en radiografías panorámicas digitales, pertenecientes a individuos adultos, de 20 y 40 años, que acudieron al Servicio de Imagenología de la Facultad de Odontología de la Universidad Nacional Mayor de San Marcos y se comparó con la edad cronológica de cada individuo. Resultados: Los resultados de las correlaciones fueron significativas, especialmente para los segundos molares en el sexo masculino (r = 0.814, r2 = 0.663). Conclusión: La aplicación del método de índice coronario dental es eficiente y la ecuación de regresión lineal encontrada muestra mayor aproximación en la estimación de la edad del individuo.

“…The volume of the pulp chamber reduces within a tooth with advancing age due to the continuous growth of dentin tissue adjacent to the pulp.

Maximum likelihood estimate of life expectancy in the prehistoric Jomon: Canine pulp volume reduction suggests a longer life expectancy than previously thought

Recent theoretical progress potentially refutes past claims that paleodemographic estimations are flawed by statistical problems, including age mimicry and sample bias due to differential preservation. The life expectancy at age 15 of the Jomon period prehistoric populace in Japan was initially estimated to have been ∼16 years while a more recent analysis suggested 31.5 years. In this study, we provide alternative results based on a new methodology. The material comprises 234 mandibular canines from Jomon period skeletal remains and a reference sample of 363 mandibular canines of recent-modern Japanese. Dental pulp reduction is used as the age-indicator, which because of tooth durability is presumed to minimize the effect of differential preservation. Maximum likelihood estimation, which theoretically avoids age mimicry, was applied. Our methods also adjusted for the known pulp volume reduction rate among recent-modern Japanese to provide a better fit for observations in the Jomon period sample. Without adjustment for the known rate in pulp volume reduction, estimates of Jomon life expectancy at age 15 were dubiously long. However, when the rate was adjusted, the estimate results in a value that falls within the range of modern hunter-gatherers, with significantly better fit to the observations. The rate-adjusted result of 32.2 years more likely represents the true life expectancy of the Jomon people at age 15, than the result without adjustment. Considering ∼7% rate of antemortem loss of the mandibular canine observed in our Jomon period sample, actual life expectancy at age 15 may have been as high as ∼35.3 years.
