Avaliação clínica da sensibilidade pós-operatória em restaurações oclusais com 3 sistemas adesivos: 3 passos (Scotchbond MP Plus), 2 passos associado a dessensibilizante (Gluma Confort Bond + Dessensitizer) e de 1 passo-auto-condicionante simplificado (I Bond)

Abstract

The main objective of this present clinical study was to assess the post operative sensitivity in occlusal adhesive restorations performed with 3 different systems. It was selected teeth with no previous pulpal pathology, with minor decay lesions or unsatisfactory restorations which would produce class I swallow to median depth cavities. The buccal-lingual dimension would also respect ½ of the entire length. The details of the cavity preparations were recorded by digital photography, silicone impression and their respective cast models which would be used to help in future analysis. All restorations were prepared under rubber dam isolation to avoid any contamination. Sixty cavities were cut and restored with the following systems: 20 teeth were restored with SBMP-Plus adhesive and Supreme restorative material 20 teeth were restored with Gluma Confort One Bond + Dessensitizer and Supreme restorative material 20 teeth were restored with I Bond adhesive system and Supreme restorative material. After 48 hours and seven days the patients were recalled and the post operative sensitivity assessed. First of all was obtained a report from each patient according to the post operative sensations. In a second moment the restored teeth were subjected to thermal, pressure and percussion tests. The results obtained from both data showed that there were no post operative sensitivity on the restored teeth. There was no need for statistical analysis.
