In this study, we aimed to demonstrate changes in the surface roughness and microhardness of three different restorative materials routinely used pediatric dentistry (composite, compomer resin-modified glass ionomer cement (RMCIS)) response continuous daily exposure gastric acid. Twelve samples each type material were prepared. Eleven specimens included acid cycle. The ten measured before after...

OBJECTIVE To report on a three-year clinical evaluation of the gingiva-coloured compomer (Comp Natur, Voco, Germany). METHODS Twelve patients with cervical lesions as a result of either gingival recession or worn root dentine were included in this study. In total, 106 restorations were evaluated by two examiners at baseline, 6-month and 3-year recalls. RESULTS Ninety-nine restorations (99/1...

Giomer is a relatively new class of restorative material with aesthetics, handling and physical properties of composite resins, and benefits of glass ionomers: high radiopacity, antiplaque effect, fluoride release, and recharge. To verify the superior properties of Giomers, in this study, a deep morphological characterization has been performed with an in vitro comparative study among a Giomer ...

A new type of self-etching agent, the single-step adhesive, was developed. The purpose of this study was to investigate the difference in the ultrastructural features of enamel and dentin surfaces following application of the prototype single-step adhesive (EXM618, 3M, MN, USA). Extracted caries-free human premolars were used in this study. Occlusal enamels of teeth--to be used as cut surface s...
