Tooth Preparation: A Study on the Effect of Different Variables and a Comparison Between Conventional and Channeled Diamond Burs

Abstract: Within the limitations of this study, channeled burs showed no significant advantage over conventional diamond burs when evaluating temperature generation and bur durability. Moreover, the cutting efficiency of conventional burs was greater than that of channeled burs.

“…The handpiece was operated at the maximum torque and rotation speed of 200,000 revolutions per minute for 10 seconds. We set the water flow through the handpiece at 25 milliliters/ minute 19,20 and set the air pressure to achieve a normal aerosol plume. We measured the rate of suction of the HVE and the Isolite device by inserting each into a 2-liter graduated cylinder filled with 2,000 mL of water.…”

“…Es discutible el efecto nocivo que esto podría tener en el esmalte o dentina con solo un pequeño aumento de la temperatura de desgaste, sumado al grabado y el bruñido (23). El diamante podría resistir 1500 °C de calefacción en vacío y, en casos de deposición, de 800 °C a 820 °C, por lo que se concluye que el desalojo o fractura de los diamantes no está relacionado con la resistencia de los diamantes durante el proceso de corte del esmalte, sino que lo estaría con la fabricación y el tipo de proceso deposición de los diamantes utilizado de la fresa (9,22,24).…”

“…De igual forma, las altas temperaturas entre el tejido mineralizado dental y los instrumentos rotatorios pueden causar daños irreversibles en la pulpa. Del mismo modo, la irritación puede generar alteraciones morfológicas, así como necrosis de los tejidos o destrucción celular, cuando la temperatura de la pulpa sube a más de 5,5 ºC (8,9,10).…”
