Theobromine Effects on Enamel Surface Microhardness: In Vitro

Journal of Dentistry Indonesia, 2013
Dental caries is still a dental health problem in Indonesia. Fluoride, one of the dental caries prevention material, but its safety and the danger of fluorosis is still debated. Theobromine is an alkaloid compound contained in cocoa beans. Theobromine is believed to increase enamel microhardness with mineral changes in the enamel superficial layer ...

SURFACE MICROHARDNESS OF MICROHYBRID AND NANOCOMPOSITE AFTER STORAGE IN MOUTH WASHES

Journal of Ayub Medical College Abbottabad, 2022
Background: Dental composites are aesthetic direct restorative material. However, the effect of mouthwashes on the durability of the material is controversial. This study evaluated and compared the influence of mouthwash composition on the surface hardness of nanofilled (Z350XT) and microhybrid (P60) resin composites.
