This pilot study explores how Endodontists make decisions regarding the adoption of rapidly evolving technologies in clinical practice, an area with little existing literature. Graduates of an Advanced Endodontics Program were surveyed to assess the importance of 23 decision-making factors using a 5-point Likert scale. The survey was distributed via Qualtrics and remained open for 3 months, with reminders sent to participants. A total of 46 responses were received, yielding a 37% response rate. The most highly ranked factors influencing technology adoption were evidence (100%), safety/risk (97.8%), health benefits (91.3%), quality (89.1%) and post-implementation patient care quality improvement. In contrast, company representative input (15.8%), initial disruption (33.3%) and training duration (45.5%) were rated as least important. These findings provide valuable insight into the priorities of Endodontists, emphasising a strong commitment to patient-centered care and clinical rigour in technology adoption decisions.

The bony lid technique can be a highly valuable procedure when facing surgical challenges, such as the presence of a thick, intact cortical plate, associated with large periapical lesions in posterior teeth. The critical task of accurately defining the location and dimension of the bony lid is a clinical concern that demands careful consideration. This case report, through three cases, illustrates the application of dynamic navigation in guiding the determination of point positions and osteotomy angles on the buccal bone plate. Postoperative complications were not observed during the examination. Dynamic Navigation Systems (DNS) can aid in the planning of surgical approaches in large lesion cases with an intact thick buccal plate, enabling accurate access to the lesion site. The utilisation of DNS in the bony lid technique is a reliable and clinically feasible method for clinicians in complex surgical processes.

The management of complicated crown–root fractures of immature permanent teeth requires a multidisciplinary approach to address biological, functional, and aesthetic concerns. A 10-year-old boy suffered a complicated crown–root fracture of tooth 11, an uncomplicated crown fracture, subluxation and pulp necrosis of tooth 21 and subluxation of tooth 22 after falling from a bicycle. The treatment for tooth 11 involved maintaining pulp vitality with partial pulpotomy and re-attachment of the crown-root fragment after modified crown-lengthening surgery. Treatment for tooth 21 included a flexible splint, root canal therapy, placement of an apical barrier and resin composite restoration. During the 4-year follow-up, the root of tooth 11 fully developed, and the patient remained asymptomatic and achieved an aesthetically acceptable outcome. Conservative partial pulpotomy followed by adhesive reattachment of the tooth fragment with the modified crown lengthening technique can be a viable treatment for complicated crown–root fractures in immature permanent teeth.

This study aimed to compare patients' perception of postoperative pain following single- and multiple-visit endodontic therapy, and to evaluate associations between anxiety and genetic polymorphisms in the DRD2, ANKK1 and COMT genes. In this clinical trial, 67 patients were included in the first phase (34 single visit, 33 multiple visits), and 25 participated in the second phase. Saliva was collected for genetic analysis, and the State–Trait Anxiety Inventory was applied preoperatively. Postoperative pain (presence and intensity) was recorded at 24, 48 and 72 h. The number of visits was not associated with postoperative pain (p = 0.806); pain intensity was highest at 24 h in both groups (p < 0.001). Moderate anxiety was significantly associated (p < 0.05) with pain in single- and multiple-visit. A genetic association was observed between the COMT rs174675 polymorphism and the outcome (p = 0.018), with greater pain reported by individuals with the CT genotype. (#RBR-47ngbg3).

This study aimed to investigate whether root canal treatment (RCT) restores muscle symmetry by measuring the thickness of masseter and anterior temporalis muscles using ultrasonography. A self-controlled prospective observational study was conducted with patients experiencing moderate-to-severe endodontic pain and masticatory laterality. Ultrasonographic measurements of masseter and anterior temporalis muscles were taken at rest and during contraction before RCT, 1 week after treatment and 3 months post-treatment. An asymmetry index was calculated to evaluate changes in muscle thickness over time. Significant increases in masseter muscle thickness were observed on the painful side, both at rest and during contraction, while the control side showed a significant increase only during contraction. No statistically significant changes were observed in anterior temporalis muscle thickness, although a similar trend was noted. The asymmetry indices decreased significantly over time, approaching zero by the third month. RCT effectively reduces muscle asymmetry caused by endodontic pain, restoring balanced masticatory function.
