NAHSAN, Flávia Pardo Salata et al. Cavity instrumentation with chemical vapor deposition diamondcoated bur. RGO, Rev. gaúch. odontol. (Online) [online]. 2012, vol.60, n.1, pp. 99-103. ISSN 1981-8637.

High- and low-speed rotary dental handpieces have been used for a long time in restorative dentistry for cavity preparation. However, problems inherent to conventional burs, such as noise, heat and vibration, have led to the development of new dental burs, such as the chemical vapor deposition diamond-coated bur. Its advantages are many, such as less noise, less pain for the patient, precise cutting, conservative cavity preparation, longer lifetime, less injury to the dental structures, no cutting of soft tissues and easier access of the carious lesion. This case report uses a chemical vapor deposition diamond-coated bur to prepare a cavity by direct proximal access, preserving the marginal ridge. The cavity was then filled with glass ionomer cement. The clinical outcome was satisfactory. Direct access to the cavity was possible because of the chemical vapor deposition diamond-coated bur, resulting in comfort for the patient and dentist.
