This study evaluated and compared the sealer thickness and interfacial adaptation of bioceramic sealers (Sankin Apatite III, MTA Fillapex(®), EndoSequence(®) BC) to root dentin against AH Plus(®) sealer. Sixty extracted single-root premolars were prepared and equally divided into four groups. Sealers were labeled with 0.1% Rhodamine B fluorescent dye. Roots were dissected along the transverse plane at 1 mm (apical), 3 mm (middle), and 6 mm (coronal) levels. Sealer-to-whole canal area ratio was evaluated. Percentage of gap-containing region to canal circumference was calculated using a confocal laser microscope. Sealer thickness was significantly higher at apical and middle levels than at coronal level. EndoSequence BC had the significantly highest thickness compared with MTA Fillapex and AH Plus. The coronal level had significantly less interfacial gaps compared with apical and middle levels. Bioceramic sealers showed more gaps compared with AH Plus, with no significant differences among them.

Objectives: This study evaluates the effect of different irrigation solutions for postoperative pain in the regenerative endodontic treatments (RET) of necrotic teeth with open apex.
Materials And Methods: This study included necrotic, deeply carious lower molars of 42 patients. Access cavities of the teeth were opened and working lengths were measured at the first visit.

Female genital prolapse, especially apical prolapse, significantly affects women's health and quality of life. Sacrospinous hysteropexy is a widely used surgical procedure to address this condition, presenting few postoperative complications. However, one of the reported complications is neuropathic pain resulting from damage to the branches of the pudendal nerve.

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.
Negative Predictors of Tooth Extraction in the Management of Odontogenic Sinusitis in a Japanese Patient Population: A Retrospective Study.

There are no clear guidelines for deciding between endoscopic sinus surgery and tooth extraction for the treatment of odontogenic sinusitis. Furthermore, tooth extraction does not necessarily improve sinusitis and eventually results in additional endoscopic sinus surgery. The present study aimed to retrospectively investigate negative predictive factors of tooth extraction for odontogenic sinusitis.

Background: Left ventricular unloading is needed in patients on extracorporeal life support (ECLS) with severely impaired left ventricular contractility to avoid stasis and pulmonary congestion, and to promote LV recovery. The presence of thrombi in the LV precludes the use of conventional active unloading methods such as transaortic microaxial pumps or apical LV vents. We describe placement of a vent cannula via the left atrial appendage (LAA) as a useful bailout option.
