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

Abstract

This clinical report presents the benefits of using CVD diamond burs coupled with an ultrasonic handpiece in the treatment of incipient caries. CVD diamond burs coupled with an ultrasonic device offer a promising alternative for removal of carious lesions when ultraconservative cavity preparations are required. Additionally, this system provides a less-painful technique for caries removal, with minimal noise.

Cytotoxicity evaluation of nanocrystalline diamond coatings by fibroblast cell cultures

“…To date, only chemical vapor deposition of microcrystalline diamond (MCD) has been reported in the literature [11,12], and, to the best of our knowledge, there are no references about the use of NCD on dental burrs. Clinical application of MCD-coated dental burrs, mounted on an ultrasonic handpiece, allow for a more precise cavity preparation in hard tissue ablation, resulting in a greater conservation of sound tooth structure [14]. Further, this system allows a higher angulation during tissue ablation and this makes interproximal preparation and finishing safer, reducing the chances of hitting adjacent structures [14].…”

“…Further, this system allows a higher angulation during tissue ablation and this makes interproximal preparation and finishing safer, reducing the chances of hitting adjacent structures [14]. In addition, patient discomfort, which is usually associated with mechanical vibrations, is greatly reduced [14]. Even with the early satisfactory clinical results with MCD diamond burrs, NCD may additionally improve the burr performance due to its lower surface roughness and higher toughness when compared to MCD [1].…”

Influence of CVD Diamond Tips and Er:YAG Laser Irradiation on Bonding of Different Adhesive Systems to Dentin

“…2 The unfavorable factor in the use of total-etch adhesive systems is the sensitivity of the technique and protocol used with caution, due to the high number of steps and the subjectivity in obtaining or retaining moisture dentin, enabling the occurrence of an incomplete impregnation of the adhesive to dentin. [3][4][5] In order to decrease the sensitivity of the technique emerged the self-etching adhesive systems, which dispense etching, washing and drying steps. In these systems, an acid solution is applied on dentin without smear layer removal, which is dissolved or incorporated into the hybrid layer.…”

“…These probes are coupled to an ultrasound machine, causing an oscillatory movement with effective cleaning power, as the ultrasonic action form air bubbles in a liquid, which produces turbulent fluid, releasing energy and moving particles. 3,17 Potential advantages of this preparation method are reduced noise, minimal damage to the gingival tissue, extended bur durability, improved proximal cavity access, reduced risk of hitting the adjacent tooth resulting from the high inclination angles, and minimal risk to the patient of metal contamination. 3 Conservative cavity preparation with well-defined walls and finishing margins can be obtained when CVD tips are used.…”
