Irrigation in Endodontics: Polyhexanide Is a Promising Antibacterial Polymer in Root Canal Treatment.

Background: chronic apical periodontitis is a common pathology in dentistry, especially in endodontics. It is necessary to systematize data concerning commonly used irrigation solutions. The development of new protocols for endodontic treatment is a very promising direction.

Second Mesiobuccal Canal Evaluation Features with Cone-Beam Computed Tomography.

Aim: The aim of the study is to evaluate the difference in MB2 prevalence with different slice thicknesses in maxillary first molars.

Materials And Methods: Two hundred nonfilled MB2 canals in maxillary first molars of 156 people (75 females and 81 males) aged from 20 to 73 years old were evaluated with CBCT with different slice thicknesses: 0.5 mm, 1 mm, 3 mm, and 10 mm.
