14. Avaliação da influência do laser de Er:YAG no selamento de cavidades de cárie radicular induzidas in vitro e restauradas com cimentos de ionômero de vidro / Evaluation of the influence of the Er:YAG laser on the sealing of in vitro induced root caries cavities restored with glass ionomer cements
Failures of root caries restoration such as microinfiltration and secondary caries are mostly due to the difficult to reach the lesions and to the types of substrate. Thus, there is a constant search for new dental materials and caries removal techniques in order to minimize or extinguish these failures. The aim of this study was to induce root caries in vit

15. Evaluación de la dureza superficial en amalgamas en función de tipos de aleaciones, momentos y tipos de pulimentos
The aim of this study was to analyze in vitro surface hardness (micro-indentation tester Wolpert) of different types of amalgam alloys varying the technique and polishing time. Tested were the amalgam: Velvalloy, Permite e Dispersalloy. For each material, 2 polishing techniques were accomplished: T1 (bladed finishing burs + abrasive rubber points + pumice-wa

16. Avaliação do laser Er:YAG como condicionador de esmalte e dentina para procedimento de união a materiais resinosos
The purpose of this study was to verify: 1) the energy levei that could produce the morphologic aspect similar to dental tissues conditioned with phosphoric acid on dental tissues irradiated by Er:Y AG (Yttrium aluminium gamet Y ~L5012) laser; 2) the tension bond strength of an adhesive system applied over enamel and dentin, after pretreatment with phosphori
