Traumatic dental injury in permanent teeth: knowledge and management in a group of Brazilian school teachers.

Background/aim: School is a place with a high frequency of dental trauma, and several studies have shown that teachers' knowledge in how to act during acute dental emergencies is lacking. Therefore, this study aimed to assess the knowledge and actions of a group of Brazilian school teachers relative to dental trauma in permanent teeth.

Materials And Methods: A cross-sectional, observational study, from 27, schools randomized by lot was performed.

Evaluation of bone width lateral to the mandibular canal as an alternative approach for implant installation.

Purpose: The objective of the present study was to realize an indirect morphometric evaluation of bone thickness lateral to the mandibular canal.

Material And Methods: In 30 partially or totally edentulous dry jaws, the first and second molar areas were analyzed using computed tomography.

Results: The findings indicated that 28.

Effectiveness of implant surface decontamination using a high-pressure sodium bicarbonate protocol: an in vitro study.

Objectives: To evaluate the effectiveness of a high-pressure sodium bicarbonate spray protocol to decontaminate implant surfaces intentionally inoculated with bacteria.

Materials And Methods: Twenty commercially pure titanium implants, 10 with machined surfaces and 10 with rough surfaces, were inoculated with Streptococcus sanguis and then submitted to a decontamination protocol using a high-pressure sodium bicarbonate spray device for 1 minute under aseptic conditions.

Results: After the application of the decontamination protocol, all bacterial cells were removed from the tested implants, regardless of surface roughness.

An in vitro model to evaluate the accuracy of guided surgery systems.

Purpose: An in vitro model was developed and tested to evaluate the precision of guided implant systems. The accuracy of dental implants placed with a flapless technique was analyzed using a stereolithographic template in vitro. Differences between the virtual and actual positions of the implants were measured.

Morphometric analysis of the effects of LactoSorb bioabsorbable plates on the craniofacial growth of rabbits using computed tomography.

This study investigated the effect of bioabsorbable plates and titanium microscrews on the growth of the craniofacial skeleton of rabbits (Oryctolagus cuniculus) in the neonatal period. All animals underwent surgery at seven weeks of age and were killed at twenty-four weeks. In the study group, LactoSorb plate and PROMM titanium microscrews were positioned across the coronal suture.
