[Clinical pattern of secondary dental caries in relation to tissue defect class and type of filling material].

The purpose of the study was assessment of the development of secondary caries in relation to filling type in various classes of carietic dental tissue defects. The study was carried out in 320 patients aged 16 to 55 years and 3884 teeth were examined. Out of this material 2423 teeth were filled: with amalgam--853, with silica cement--1197, with composites--373. Secondary caries was found in 1341 teeth (56.34%). In teeth filled with amalgam in classes I and II of carietic defect in women secondary caries was noted in 27.26% and 47.73% of cases respectively. In case of composite filling secondary caries was found in 72.12% and 81.82% of fillings. In class III of carietic defects in women with fillings with composite materials secondary caries developed in 48.8%, and after filling with silica preparations in 55%. In class IV secondary caries was present at 45% of composite fillings and 77.78% of silica cement fillings. In class V secondary caries was found at 11.42% of amalgam fillings and 36.67% of composite fillings, and in 45% at silica cement fillings. Similar values were found in men.
