title: pH stabilizing properties of a posterior light cured resin composite: an in vivo study.
abstract: This study evaluated, in vivo, the pH stabilizing properties of a posterior resin composite (Ariston pHc, Vivadent Ets, Schaan/Liechtenstein). Fifteen human subjects with four or more active carious lesions were selected. Their salivary pH, in relation to the occlusal surface of these lesions, was recorded. The teeth were restored with resin composite, and the pH in relation to the restorations was recorded one day, one week, one month and two months postoperative. Results showed that the resin composite countered the acidic pH of saliva and maintained it at levels where demineralization would not occur.
