Radiolucent halos beneath composite restorations do not justify restoration replacement.

Purpose: To determine the correlation between the presence of radiolucent areas (RA) beneath composite restorations and gaps and remaining demineralized tissue (RDT).

Methods: 50 extracted teeth (sound and carious) were studied. After caries removal, cavities were filled.

Effects of lactose-containing stevioside sweeteners on dental biofilm acidogenicity.

The aim of this study was to evaluate the effect of a commercial lactose-containing stevioside sweetener on biofilm acidogenicity in vivo. Nine volunteers refrained from brushing their teeth for 3 days in five phases. On the 4th day of each phase, the pH of the biofilm was measured by the "Strip method".
