Effect of Dentin Thickness on Root Surface Temperature of Teeth Undergoing Ultrasonic Removal of Posts

“…When ultrasonically activating a post, care should be taken to ensure that it does not overheat (4 -7). Most authors recommend using a cooling water spray to minimize heat production in the post (3)(4)(5)(6)(7)(8).…”

The Effect of Ultrasonic Post Instrumentation on Root Surface Temperature

“…M anipulation of tooth structure through preparation, ultrasonic scaling, rotary instrumentation, obturation, and post space preparation techniques raise the temperatures of dental tissues (1)(2)(3)(4)(5)(6)(7). If a sufficient amount of heat is transferred to supporting tissues, thermal injury may result (8).…”

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

“…It is also claimed that the presence of the channel(s) allows water to remain in contact with the tooth surface and re‐circulate within the groove(s), providing continuous cleaning and rapid heat dissipation 17 . Few studies have been done to confirm this hypothesis 18–20 and these were not entirely conclusive due to inadequate control of some potentially important experimental variables. To our knowledge, no study has systematically evaluated all the variables related to high‐speed tooth cutting.…”
