“…12 Thomas demonstrated both clinically and histologically that because of these changes, cavity preparation could be performed painlessly without local anesthetic agents, a fact noted empirically by earlier dental operators. 13 Cementum deposition decreases in general in aging, particularly at the cementoenamel junction. Clinically, this increases the vulnerability of the cervical tooth areas to decalcification and decay.…”

H ISTOPATHOLOGIC studiesl-4 have rather precisely defined the clear-cut microscopic abnormalities that accompany gingival lesions. Inflammations, degenerations, dystrophies, infiltrations, and tumors have been categorized, illustrated, and contrasted with the description of the hypothetic normal.5' 6 Concepts of normal gingival structure remain static, in contrast to the dynamic understanding of pathologically induced variations.Normal oral mucosa has been studied with emphasis on variations in selected areas of the mouth,7 from the point of view of age and sex differences,8 functional changes,9 and the whole range of metabolic and hormonal deviations.10 An indication of the broadness in pattern which gingival histology .may take is given in one text which grants the possibility of considering the surface epithelium in keratinized, parakeratinized, or nonkeratinized forms as within the normal range.' Boundaries of gingival normality, as rigidly defined in texts, require extension to include a broader range of variation.Of seventeen specimens studied in one report,"2 not one could be found which registered complete adherence to the picture of "ideal normal gingiva." Features tabulated included cellular infiltration, degree of cornification, and the presence of inflammatory cells in the subepithelium. The inclusion in this study of subepithelial structures focuses attention on the lability of corium tissue. The health status of the gingivae has been equated with thickness and keratinization of the epithelial mantle,'3 while consideration of variant patterns of subepithelial architecture has been relatively less stressed. Epithelial nutrition and physiologic changes derive from the lamina propria of vascular and reactive corium. This internal effect requires consideration as well as external phenomena, such as trauma and superficial inflammation.It is the purpose of this report to broaden the concept of normal gingiva] structure through a study of variations. The line of demarcation between normal and pathologic gingivae is not sharp and clearly defined histologically; pathology implies recognition of degree of variation from normal. The study explores the degree of variation apparent in gingival specimens which, despite mutual microscopic differences, are classified as normal on the basis of clinical and symptomatic findings. METHODS AND MATERIALSThirty-eight gingival biopsy specimens were removed from both in-and outpatients at Montefiore Hospital, New York. The subjects ranged in age from 19 to 64 years; twenty-two were men and sixteen women. Patients were

“…Además, se destacan aquellas investigaciones que analizanla composición bioquímica de los tejidos dentales y los cambios que se observan relacionados con la edad. No obstante, la finalidad de estos trabajos suele estar orientada a su aplicación terapéutica (Atsu et al 2005, Burke y Samarawickrama 1995, Carrigan et al 1985, Larmas 2001, Montoya et al 2015, Park et al 2008, Regalado Ruiz y Del Angel 2005, Senawongse et al 2006, Thomas 1989).…”

Objetivos generales - Evaluar la utilidad de las piezas dentarias permanentes como elementos del sistema esquelético a ser utilizados para estimar la edad y el sexo en individuos adultos. Objetivos específicos - Identificar aquellos rasgos dentales que varíen en relación con la edad en individuos que culminaron su crecimiento y desarrollo. - Evaluar la eficacia de métodos ya existentes basados en características dentales y generados en otras poblaciones para estimar la edad en individuos adultos. De presentar escaso poder predictivo, generar una nueva propuesta a partir de la población estudiada. - Evaluar las diferencias odontométricas entre los sexos y su potencial utilización para estimar el sexo. - Evaluar la precisión de metodologías generadas en otras poblaciones para estimar el sexo a partir de la dentición permanente, y en caso de presentar baja precisión elaborar una nueva propuesta utilizando la muestra bajo estudio. Hipótesis - Los cambios ocasionados por el paso del tiempo a nivel microestructural ocurridos en el complejo dentino-pulpar presentan correlación con la edad cronológica individual y permiten estimar la edad de los individuos. - Las diferencias dimórficas en las dimensiones de las piezas dentarias permanentes permiten su utilización para estimar el sexo con grado aceptable de precisión.
