Comparative analysis of two navigation techniques based on augmented reality technology for the orthodontic mini-implants placement.

To analyze and compare the accuracy and root contact prevalence, comparing a conventional freehand technique and two navigation techniques based on augmented reality technology for the orthodontic self-drilling mini-implants placement. Methods Two hundred and seven orthodontic self-drilling mini-implants were placed using either a conventional freehand technique (FHT) and two navigation techniques based on augmented reality technology (AR TOOTH and AR SCREWS). Accuracy across different dental sectors was also analyzed.

Photodynamic therapy in endodontic root canal treatment significantly increases bacterial clearance, preventing apical periodontitis.

Objective: To analyze the antimicrobial activity of photodynamic therapy as an adjunct to conventional endodontic treatment, particularly against Enterococcus faecalis.

Method And Materials: A total of 42 single-rooted teeth obtained from 33 patients with apical periodontitis were included. Sampling was developed in three stages: (1) immediately after accessing the root canal, (2) after chemical and mechanical instrumentation, and finally, (3) after photodynamic therapy application.

Diagnosis and endodontic treatment of type II dens invaginatus by using cone-beam computed tomography and splint guides for cavity access: a case report.

Background And Overview: Dens invaginatus (DI) is defined as a rare dental malformation. The inherent structural variants of this anatomic disorder make it difficult to perform conventional endodontic treatment procedures by means of a conservative access cavity. In this clinical case report, the authors describe the treatment of a type II DI by means of guided splints for cavity access.

Management of perforating internal root resorption with periodontal surgery and mineral trioxide aggregate: a case report with 5-year follow-up.

Internal root resorption (IRR) is characterized by progressive loss of tooth substance initiating at the root canal wall as a result of clastic activity. The use of periodontal surgery and mineral trioxide aggregate is a good approach to repair lesions with periodontal communication (perforating IRR). This case describes the treatment and follow-up of a maxillary central incisor with perforating IRR in a 56-year-old male patient where root canal treatment, periodontal surgery, and white mineral trioxide aggregate were employed to achieve complete repair and to restore function.
