Relación esmalte-cemento y presencia de caries

Choquet described 4 cases of associations between enamel and cement. The present work examines the percentage incidence ofthese associations and the possible individual variations and topographic variations within a single tooth. We examined the possibility that the caries should be related to a par...

The present work examines the percentage incidence ofthese associations and the possible individual variations and topographic variations within a single tooth. We examined the possibility that the caries should be related to a particular case of association. One hundred and forty teeth were studied. They were sectioned axially through healthy areas. 8oth enamel-cement limits were assessed at high magnification. A further perpendicular section was performed to complete the readings. Polished sections were examined and those of diagnostic significance were wom down to be examined under transmitted ligth. Those fixed in 10% formalin, were submitted to PAS staining to interpret PAS + cement and the process of cariogenic decalcifi~ation.

En este trabajo se estudia en qué porcentajes se encuentranesÍlis relaciones y las probables variaciones individuales y por caras en una misma pieza dentaria. La posibilidad de que la caries guarde alguna vinculación con un determinado caso. Se estudiaron 140 piezas dentarias las que fueron cortadas axialmente buscando que el corte, adecuadamente refrigerado, se oriente por sectores indemnes o sanos. Lectura con lupa de gran aumento en ambos límites cemento-adamantinos, completando las lecturas con otro corte perpendicular sobre los ya realizados. Los cortes, pulimentados, se observaron con lupa y aquellos de importancia diagnóstica fueron desgastados para observar por transparencia. Aquellos fijados en formol al 10% fueron sometidos a la reacción de PAS para interpretar el cemento PAS positivo y el proceso de descalcificación cariogénica. Se encontró al cemento cubriendo al esmalte en un 23,5 7%, al esmalte contactando con cemento en un 35%, al esmalte y cemento sin contactar en un 39,29% y al esmalte sobre cemento en un 2, 14%. La caries en estadías iniciales estuvo presente en un 37% del total de casos estudiados, iniciándose en cemento (15,20%), en Dentina (9,60%), en la unión de Esmalte y Cemento (9,20%) o en Esmalte (2%).
