AI Article Synopsis
- The study aimed to compare the shaping ability of two dental instruments, XP-endo Shaper and TRUShape, in prepping moderately curved root canals using advanced imaging technology.
- Twenty maxillary premolars were divided into two groups and analyzed before and after root canal treatment to evaluate various factors like dentin removal and canal anatomy.
- Results showed no significant differences in effectiveness between the two instruments, indicating that both maintained the natural structure of the canals and performed equally well in reducing untreated surfaces and canal deviation.
Article Abstract
Introduction: The aim of this study was to evaluate and compare the shaping ability of XP-endo Shaper (XP; FKG Dentaire, La Chaux-de-Fonds, Switzerland) and TRUShape (TS; Dentsply/Tulsa Dental Specialties, Tulsa, OK) during the preparation of moderated curved root canals using micro-computed tomographic imaging.
Methods: Twenty human maxillary premolars with 2 roots were randomly separated into 2 groups of 10 teeth, which were scanned before and after root canal preparation using the SkyScan 1275 X-ray microtomograph (Bruker micro-CT, Kontich, Belgium) at a nominal resolution of <4 μm. Premolars and irrigant were maintained at 37° before and during preparation; group 1 was treated using XP and group 2 with TS. After preparation, researchers measured the amount of dentin removed, untreated superficies of canal walls, root canal volume, degree of canal transportation, and centering ability. Values of central tendency and dispersion were calculated using Statgraphics Centurion XV software (StatPoint Technologies, Inc, Warrenton, VA); means and median were compared using the Mann-Whitney-Wilcoxon test. The level of significance was set at 5% (P < .05).
Results: No significant statistical differences were observed between the 2 groups in shaping ability, untreated superficies of canal walls, degree of canal transportation, and centering ability (P > .05).
Conclusions: Instrumentation of moderately curved root canals using the XP single file and the TS file system were equally effective. XP and TS maintained the original anatomy of the root canals and showed a similar percentage of untreated canal walls, centered ability, and minimal apical transportation.

Background: Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a painful disorder primarily affecting the incisor teeth of horses over 15 years of age. Clinical signs of the disease include prehension problems, halitosis and in severe cases weight loss. The disease predominately affects the reserve crown and presents as a loss of dental tissue and excessive build-up of cementum.

BACKGROUND Different temperature conditions can affect the efficiency of irrigation solutions and consequently the ability of canal sealers to bond to root canal walls. The aim of this endodontic study was to evaluate the effect of irrigation solutions at different temperatures on the bond strength of a bioceramic-based root canal sealer. MATERIAL AND METHODS Root canal preparations were completed through irrigation with the following solutions: Group 1 was irrigated with 5 ml NaOCl (sodium hypochlorite) +5 ml EDTA (Ethylenediamine tetra-acetic acid) (22°C); Group 2 was irrigated with 5 ml NaOCl +5 ml EDTA (37°C); Group 3 was irrigated with 5 ml NaOCl +5 ml GA (Glycolic acid) (22°C); Group 4 was irrigated with 5 ml NaOCl +5 ml GA (37°C), Group 5 was irrigated with 20 ml Dual Rinse® HEDP (Etidronate) - NaOCl mixture (22°C); and Group 6 was irrigated with 20 ml of Dual Rinse® HEDP mixture (37°C).

Background: This study assessed stress distributions in simulated mandibular molars filled with various materials after the removal of fractured instruments from the apical thirds of the root canals.
Methods: Finite element models of the mesial and distal root canals were created, where fractured instruments were assumed to be removed using a staging platform established with a modified Gates-Glidden bur (Woodpecker, Guangxi, P.R.

Renal tubular acidosis (RTA) is a group of disorders in which there is an alteration in acid-base homeostasis because of the impairment of nephrons to excrete hydrogen ions or reabsorb bicarbonate ions, resulting in chronic metabolic acidosis. RTA is an important cause of rickets, particularly 'resistant rickets'. Dental manifestations frequently reported in patients with RTA include enamel hypoplasia and amelogenesis imperfecta, affecting permanent dentition.

Objectives: This study aimed to compare the marginal adaptation of a cold ceramic (CC) sealer with the single-cone obturation technique with that of an AH-26 sealer with the lateral compaction technique in single-canal teeth.
Materials And Methods: In this in vitro experimental study, the root canals of 24 extracted single-rooted single-canal teeth were instrumented to F3 files by the crown-down technique and randomly assigned to 2 groups (n = 12). The root canals were obturated with a CC sealer and single-cone obturation technique with 4% gutta-percha in group 1 and with an AH-26 sealer and lateral compaction technique with 2% gutta-percha in group 2.
