Objectives: In this study we evaluated heat generation during the low-speed drilling procedure without irrigation.
Materials And Methods: Ten artificial bone blocks that were similar to human D1 bone were used in this study. The baseline temperature was 37.0℃. We drilled into 5 artificial bone blocks 60 times at the speed of 50 rpm without irrigation. As a control group, we drilled into an additional 5 artificial bone blocks 60 times at the speed of 1,500 rpm with irrigation. The temperature changes during diameter 2 mm drilling were measured using thermocouples.
Results: The mean maximum temperatures during drilling were 40.9℃ in the test group and 39.7℃ in the control group. Even though a statistically significant difference existed between the two groups, the low-speed drilling did not produce overheating.
Conclusion: These findings suggest that low-speed drilling without irrigation may not lead to overheating during drilling.

Introduction: The dynamic navigation system (DNS) in endodontics presents a significant learning curve. This cross-sectional study aimed to assess the number of cases required to achieve consistent performance in DNS-assisted treatment of maxillary anterior teeth with pulp canal calcification.
Methods: A series of DNS procedures were performed on 45 calcified maxillary anterior teeth with pulp necrosis by a single endodontist who had no prior clinical DNS experience.
Article Synopsis
- The study aimed to compare the effectiveness of low-speed drilling versus conventional drilling in implant placement surgery, focusing on accuracy, procedure duration, and bone chip accumulation.
- There were no significant differences in accuracy between the two methods, but low-speed drilling resulted in longer procedure times and the collection of larger bone fragments.
- The findings suggest that while low-speed drilling doesn't compromise accuracy, it may offer benefits in terms of harvesting more substantial bone chips that could support healing, making it a viable alternative to conventional drilling.

Study Design: A randomized, controlled, single-blind clinical trial.
Objective: To assess and compare patient-reported outcome measures (PROMs) between low-speed drilling without irrigation and high-speed drilling with irrigation for implant site preparation.
Patients And Methods: The study adhered to the Declaration of Helsinki principles, obtained approval from the local Ethics Committee, was registered on ClinicalTrials.

This study aimed to evaluate various biomechanical parameters associated with the primary stability of Maestro and Due Cone implants placed in low-density artificial bones, prepared using high-speed drilling with irrigation and low-speed drilling without irrigation. The insertion torque (IT), removal torque (RT), and implant stability quotient (ISQ) values were recorded for Maestro and Due Cone implants placed in low-density polyurethane blocks (10 and 20 pounds per cubic foot (PCF) with and without a cortical layer) prepared using high-speed and low-speed with or without irrigation using a saline solution, respectively. A three-way ANOVA model and Tukey's post-hoc test were conducted, presenting data as means and standard deviations.

Introduction: The removal of residual resins is a routine procedure in orthodontic clinics and of great importance to the final result of the treatment.
Objective: To evaluate the main methods of residual resin removal used by orthodontists, and the main reasons for choosing these methods.
Methods: A questionnaire consisting of 21 questions: 6 relating to demographic data and the other 15 relating to two methods used to remove residual resins (drills or pliers) was sent by e-mail to orthodontists registered with the Regional Councils of Dentistry of São Paulo and Rio de Janeiro (Brazil) within April and June, 2023.
