Objective: The purpose of this study was to evaluate if the apical third enlargement of root canal is the determinant factor for the repair of periapical lesions in endodontic treatment.
Methods: Eighty upper and lower incisors, canines and premolars with periapical lesions were randomly divided in 2 groups and were treated by undergraduate students. Canals were instrumented with up to 3 files in group I (n = 40) and up to 4 files in group II (n = 40) 1 mm short of the apex and were filled with a calcium hydroxide dressing. After removing calcium hydroxide 14 days later, both groups were filled using the lateral condensation technique. In the 2-year follow-up, a few patients did not return, and some cases did not present conditions for accurate comparisons. Therefore, only 43 patients (24 in group I and 19 in group II) presented conditions for radiographic comparisons. Data were statistically analyzed using Fisher's exact test.
Results: Comparison of the initial and follow-up radiographs showed that 22 out of 24 (91.67%) patients in group I and 17 out of 19 patients (89.47%) in group II showed repair. Statistical analysis revealed no significant differences between the groups (P>.05).
Conclusion: The results of this study show that the apical third enlargement did not alter the outcome of endodontic treatment of teeth with periapical lesion performed by undergraduate students.

Bifrontal Craniectomy: A High-Yield Surgical Training Tool.
Cureus
December 2024
Department of Medical Education, Geisinger Commonwealth School of Medicine, Scranton, USA.
Bifrontal decompressive craniectomy (DC), which was once a popular technique for treating midline mass lesions, has seen a notable decline in its therapeutic use within modern neurosurgery. Despite its diminished clinical use, the procedure offers considerable value as an educational tool for surgical training. This study used a Thiel-embalmed cadaver to demonstrate the bifrontal DC procedure, including a Souttar incision, strategic (MacCarty, zygomatic, and apical) keyhole/burr hole placement, superior sagittal sinus suturing, left frontal lobe decortication, and microscopic visualization of the anterior cranial fossa.

State Key Laboratory of Oral Diseases & National Center for Stomatology & National Clinical Research Center for Oral Diseases, West China Hospital of Stomatology, Sichuan University, Chengdu, China.
Background: Autogenous tooth transplantation offers significant advantages and promising success rates for replacing non-retainable teeth. This study aimed to investigate the prognostic factors, especially the impact of root canal treatment (RCT), of autotransplanted teeth in an up-to-6-year follow-up cohort of 167 teeth in Southern China.
Methods: We enrolled adult patients from the Southern Medical University-Shenzhen Stomatology Hospital between 2017 and 2023.
Comparison of Debridement Efficacy of Two Irrigating Systems Endovac and Conventional Needle in Primary Tooth Root Canals: An Study.
Int J Clin Pediatr Dent
November 2024
Department of Pediatric and Preventive Dentistry, PDM Dental College and Research Institute, Bahadurgarh, Haryana, India.
Aim: The purpose of the study is to evaluate how well the Endovac system and conventional needle irrigation work to remove smear layers (SR) from primary teeth root canals.
Materials And Methods: Fifty extracted human primary teeth were divided into two equal sections vertically, then positioned within an acrylic model that was secured with screws. Group A (Endovac), = 25, and group B (traditional needle), = 25.
An unusual case of dens invaginatus on a mandibular second molar: a case report.
Restor Dent Endod
January 2025
Faculty of Dental Surgery, University of Strasbourg, Strasbourg, France.
The present case report describes the endodontic treatment of a type III B dens invaginatus (DI) in a three-rooted mandibular second molar since the invagination invades the root and extends apically. Clinical and cone-beam computed tomography examination of the mandibular second molar showed a broadened coronal morphology, DI, a third root, periapical radiolucency, and compression of a distal root canal by the invagination, which developed an atypical semilunar shape. The tooth was diagnosed with pulpal necrosis, symptomatic apical, and peri-invagination periodontitis.

Department of Dental Sciences, Faculty of Medicine, University of Liege, Liege, BEL.
Background Fracture of nickel-titanium (Ni-Ti) instruments in root canals is commonly associated with compromised outcomes in endodontic treatment. There is no single, universally accepted approach for managing this complication. The objective of this study is to evaluate the effectiveness of an Nd: YAP laser-assisted protocol in removing fractured Ni-Ti files in teeth with minimal root curvature (less than 15 degrees).
