Purpose: This survey aims to assess the understanding, viewpoints, and methods employed by undergraduate dental students in the fourth and fifth grades regarding broken endodontic instruments in root canal procedures.
Methods: A survey comprising 27 questions across three sections-demographic information, practical application, and knowledge-approach-awareness inquiries-was developed. It was distributed to 282 students either in person or via a link shared through WhatsApp groups using Google Forms.
Results: Out of the total 219 respondents (77.6%), 10.6% experienced instrument breakage once during their clinical internship, while 2.8% encountered it more than once. The majority (86.7%) did not face instrument fracture incidents. Among these occurrences, it was observed that endodontic instruments were most commonly separated in molars, accounting for 51.9%. Nearly half (48.1%) of the students noted instrument breakage during the initial attempt to reach the apical part of the canal, while 55.6% reported breakage during root canal cleaning and shaping.
Conclusions: Most dental students opted to leave the separated instrument in the root canal and proceed with filling it. Enhancing students' understanding and awareness of this matter will help prevent potential complications and enable them to handle such situations appropriately when they arise.

Background: This study compared the torsional resistance, bending stiffness, and cyclic fatigue resistances of different heat-treated NiTi files for minimally invasive instrumentation.
Methods: TruNatomy (TN) and EndoRoad (ER) file systems were compared with ProTaper Gold (PG). Torsional load, distortion angle, and bending stiffness were assessed using a custom device AEndoS, and toughness was calculated using the torsional data.

This systematic review aimed to compare postoperative pain in endodontic treatments using PIPS Er: YAG laser-activated irrigation (LAI) versus conventional needle irrigation. An electronic search was conducted to identify randomized clinical trials (RCT) investigating postoperative pain in patients who underwent root canal treatments in permanent teeth using PIPS Er: YAG laser-activated irrigation or conventional needle irrigation. Two reviewers performed study selection, data extraction, risk of bias assessment (RoB 2.

Objectives: The objective of this study is to evaluate the incidence and volume of contrast medium extrusion when activated with a laser and to compare these outcomes with those of other irrigation techniques.
Materials And Methods: Sixteen cadaver mandibles containing 116 single-rooted teeth were prepared using conventional rotary instrumentation. The teeth were randomly assigned to four irrigation groups: side-vented needle, sonic irrigation, laser activation at the orifice, and laser activation at the middle third of the canal.
Photon-counting-detector CT outperforms state-of-the-art cone-beam and energy-integrated-detector CT in delineation of dental root canals.

This experimental phantom study investigates current standard of care protocols in cone beam computed tomography (CBCT), energy-integrating-detector (EID) CT, and photon-counting-detector (PCD) CT regarding their potential in delineation of dental root canals. Artificial accessory canals (diameters: 1000, 600, 400, 300 and 200 μm) were drilled into three bovine teeth mounted on a bovine rib as a jaw substitute. The phantom was scanned in two dental CBCTs, two EID-CTs and a PCD-CT using standard clinical protocols.

Objective: To investigate the short-term effectiveness of uni-portal non-coaxial spinal endoscopic surgery (UNSES) via crossing midline approach (CMA) in the treatment of free lumbar disc herniation (FLDH).
Methods: Between March 2024 and June 2024, 16 patients with FLDH were admitted and treated with UNSES via CMA. There were 9 males and 7 females with an average age of 55.
