“…The market has seen the emergence of specifically designed zirconia-cutting burs (7) and multiple studies reporting on the cutting efficiency of these burs (8,(19)(20)(21)(22)(23)(24)(25). Cutting rate and cutting efficiency (defined as change of cutting rate over time) of a bur appear to be dependent on various factors, including the type of bur used, the coolant flow rate, the hardness of the substrate, the type of handpiece used and the force applied by the operator.…”

Cutting dental zirconia for endodontic access preparation is difficult. Therefore, this study aimed to determine cutting efficiency of various burs when cutting this material. An air turbine handpiece was used in a customised test rig to cut sintered zirconia specimens, using a conventional blue band diamond, two different zirconia-cutting diamond and a zirconia-cutting tungsten carbide bur. Position and speed of the bur were continuously determined using wireless data acquisition over two successive five-minute runs. Differences in cutting efficiency were statistically analysed. Burs were examined using light and scanning electron microscopy (SEM). All diamond burs cut zirconia more efficiently than the tungsten carbide bur. Overall, all burs showed decreasing cutting efficiency over time. SEM images showed discernible wear and damage to the cutting portion of each bur head. It is concluded that zirconia-cutting burs are advantageous regarding durability, and carbide burs are rather ineffective against carbide substrate. Cutting ZirconiaO. A. Peters et al.

“…Although electric micromotors and turbines achieve some similar results in terms of performance, such as during cavity preparation, (Kenyon et al, 2014), and have similar characteristics such as the base temperature of the equipment during use, (Rotella et al, 2013), they differ with respect to several other features. The turbines are lighter and offer a greater sense of grip and flexibility, in spite of producing a louder noise than electric micromotors (PEI et al, 2020).…”

At present, in dentistry, procedures such as prophylaxis and tooth preparation are performed with the aid of air turbines or handpieces coupled to micromotors. These micromotors can be driven by electric or pneumatic power sources. Thus, the aim of this study was to compare the handpieces coupled to electric micromotors with high speed turbines, relative to their technical characteristics, advantages and disadvantages. In this study, a literature search was conducted in three databases (Science Direct, PubMed and Capes Periodicals) with the following keywords: “Electric handpieces" and "air turbine”.” Out of a total of 105 articles found, ten scientific articles that compared the two types of equipment were included. In addition, a market survey in Brazil was carried out with five national and international brands, in order to compare technical specifications and cost. The articles showed that there were similar characteristics between the turbine and the electric handpieces, such as the force they exert on the tooth and the temperature at the base of the equipment. Furthermore, although air turbines run a lower revolution per minute (RPM), as regards noise, weight, torque and speed control, electric micromotor showed better results. Regarding the types of equipment sold, on average, the cost of electrical equipment (micromotor and multiplier handpiece) was found to be 1,595.55% higher than that of air turbines. It was concluded that the electric micromotors had some advantages in comparison with turbines, except for their lower maximum speed, and their higher cost.
