Scanning electron microscope analysis of tooth enamel treated with rotary instruments and abrasives

Observations on the Effects of Scaling and Polishing Methods on Enamel

“…[13][14][15] However, because the materials and techniques used in these studies were different compared to those used in this study, direct comparisons were not made. Statistical analysis was not applied although the observer assessing results was unaware of the treatment type.…”

The Use of CVD Diamond Burs for Ultraconservative Cavity Preparations: A Report of Two Cases

“…This causes a decrease in their cutting effectiveness by affecting the matrix that binds diamond particles to the shank. 8,9 Additionally, the use of diamond burs coupled with conventional handpieces represents an unpleasant and painful procedure for the patient. Noise and mechanical vibrations in such cases cause great discomfort for patients.…”

“…One of the main problems associated with diamond burs is their short lifetime resulting from their repeated sterilization. This causes a decrease in their cutting effectiveness by affecting the matrix that binds diamond particles to the shank 8,9 …”

"Estudo da influência de instrumentos e técnicas alternativas de preparo cavitário na resistência de união de sistema adesivos à dentina"

“…Durante a produção de pontas diamantadas convencionais, partículas de diamantes minerais ou industriais são agregadas à superfície de uma ponta de aço inoxidável por meio de um processo galvânico (BORGES et al, 1999). Os instrumentos assim confeccionados apresentam grande heterogeneidade no formato dos grãos de diamante, dificuldade na automação do processo de fabricação, rápida queda na efetividade de corte, baixa resistência ao impacto e, portanto, baixa longevidade (ARCURI et al, 1993).…”
