The effect of fluoride, released from a fluoride-containing composite resin, on secondary caries was investigated by quantitative microradiography. In all teeth investigated, less demineralization was found near the composite resin than was found at a distance of a few millimeters from the material after an acid attack. The presence of the fluoride-releasing composite resin reduced the lesion depth measured after an acid attack by about 35%. Therefore, in vivo, a reduction of recurrent caries may be expected around fluoride-containing composite resins.
通过定量显微放射照相术研究了含氟复合树脂释放的氟对继发龋的影响。在所有被研究的牙齿中，酸蚀后发现复合树脂附近的脱矿程度低于距该材料几毫米处的脱矿程度。含氟复合树脂的存在使酸蚀后测得的病变深度降低了约35%。因此，在体内，含氟复合树脂周围的继发龋可能会减少。
