Abstract


Objective: This study aims to compare the use of conventional handpiece and diamond burs CVDentus® system (CVD) for cavity preparation in children, evaluating their clinical performance and behavior during dental treatment.
Method: The sample was selected with 22 children from 36 to 60 months with incipient caries on the occlusal surface of primary teeth. Of the 22 children, 60 primary molars with incipient caries lesions were part of the sample. The caries removal, cavity preparation and restoration were performed in a single session, without local anesthesia and under relative isolation. For the cavity preparation was used two types of systems: CVD or carbide bur. The teeth were restored with glass ionomer cement conventional after completed cavity preparation. The clinical performance of each system was determined, after each session, through the scores: 1 - poor 2 - and 3 regular – good to accessing the cavity, working area view, noise and vibration and removal of carious tissue. After the each session, the behavior of children was also analyzed.
Results: No significant statistical difference was identified for accessing the cavity between the two systems (CVDentus® system and handpiece) (p = 0.1033). The CVD regarding the working area view (p = 0.0001), noise and vibration (p = 0.0001) was better than the handpiece, whilst the handpiece was better than CVDentus® system for removal of carious tissue (p = 0.0265) and behavior of the child (p =0.0169).
Conclusion: The CVD seems to be a promising alternative, however, further studies are needed in order to clarify aspects in the CVDentus® system.
