Abstract
Background: Outcomes reported in the literature do not relate cutting effectiveness of high-speed diamond drills directly to the
diamond surface amount and quality, not either their average life after a specific number of uses. Objective: To evaluate the
durability of diamond burrs in the drill active surface after doing removal in natural teeth. Methods: This ex vivo study compared
dental drills of four different brand names with 64-126 μm, round tip, conical-trunk diamond grit (ISO 850): MDT®, Swisstech®,
Pointech® and Jota®. Five 0.16 mm cuts were carried out using each dental drill on a tooth crown. The dental drills were then
analyzed under the scanning electron microscope in order to observe: a) any adhesion of diamond to substrate in the head and
body; b) condition of the diamonds in the substrate, in head and body, after 5 cuts; and c) nal condition of the dental drills.
Then a qualitative and quantitative analysis was carried out. Results: The four different dental drills showed a similar worn
condition after five uses, both in the head and body. Despite all the samples showed variations, some of them had greater evidence
of diamond fracture and displacement. Conclusion: This study suggests that the dental drills should be changed over after 5
clinical uses in order to ensure a desirable worn condition and prevent pulpal damage due to the friction.
