Abstract
Resumen Se analizaron 260 pacientes de ambos sexos, mayores de 18 años, a los cuales se les realizaron radiografías en todas las obturaciones de II clase. Esta investigación tiene como objetivo contribuir a elevar la salud de los pacientes realizando correctas obturaciones de amalgama en las cavidades de II clase de Black. Se realizó en la Clínica de Estomatología General Integral, Facultad de Estomatología del ISCM de La Habana. Se diagnosticaron 817 obturaciones de amalgama de II clase, de las cuales 518 eran correctas, o sea, el 63 % de las obturaciones y 299 defectuosas, lo que representa el 37 %. Los defectos analizados por medio de la radiografía fueron: alteraciones de la relación de contacto, contornos proximales y margen gingival. Se concluyó que radiográficamente, fue elevada la frecuencia de obturaciones de amalgama defectuosas en cavidades de II clase de Black. La alteración de los contornos proximales, fue el tipo de defecto más frecuente, siguiendo en orden la alteración de margen gingival y la relación de contacto deficiente. Por exceso de material del margen gingival se observó considerable reabsorción ósea, y por déficit, recidiva de caries. La radiografía sigue siendo un medio auxiliar de diagnóstico muy efectivo para observar defectos que clínicamente no se diagnostican correctamente.
Summary This research is aimed at contributing to improve the patient's health by making correct amalgam fillings in class II Black's cavities. It was carried out at the General Comprehensive Dental Clinic of the Faculty of Stomatology of the Higher Institute of Medical Sciences of Havana. 260 patients over 18 of boths sexes were analyzed. All the class II fillings were X rayed. 817 class II amalgam fillings were diagnosed. 518 of them were correct, that is, 63 % of the fillings, and 299 deficient, accounting for 37 %. The defects analyzed by means of X rays were alterations of the contact ratio, proximal contours and gingival line. It was radiographically concluded that the frequency of defective amalgam fillings in class II Black's cavities was elevated. The alteration of the proximal contours was the most common type of defect followed by the alteration of the gingival line and the deficient contact ratio. It was observed a considerable osteal reabsorption due to an excess of material of the gingival line, and caries relapse due to deficit. The radiography is still a very effective diagnostic tool to observe defects that were not correctly diagnosed from the clinical point of view.
