Hybridization of dental hard tissue. Scanning electrono microscopy

Iulia Saveanu, Ioan Dănilă.

The aim of this study was to analyze the ultrastructural aspects of the dental hard tissues-restorative materials interface resulted after the use of the restorative material technique [1]. Material and method: The study included 30 teeth (molars and premolars) extracted for orthodon-tic or periodontal reasons. Standard first class cavities were prepared which had cylindrical shape, a depth of 2.5 mm and the diameter of approximately 2 mm. The teeth were divided into three groups A, B, C, and were restored according to the manufacturer's indication. The materials used were: Composite Filtek Z-250 and X-flow (3M), Compoglass F, Resin Modiffied Glass Ionomer (RMGI) - Vitremer (3M ESPE), and halogen photoactivation lamp. Results: Adaptation of the restorative composite to the cavities walls showed that its adhesion to enamel margins was very good and counteracts material shrinkage efficiently if small amounts are used: the laminate technique. Conclusion: Practitioners must choose the technique that conserves the restoration as much as pos-sible.
