Background: Not only the gaps at dentin-sealer interface but also at core-sealer interface may jeopardize the outcome of root canal treatment.
Aim: The aim of this scanning electron microscopic (SEM) study was to determine which root canal sealer among AH-Plus, GuttaFlow, and RealSeal provides a superior marginal adaptation with the core obturating material in the apical third region of root canals.
Materials And Methods: Selected 30 human freshly extracted maxillary central incisors were biomechanically prepared, then divided equally into three groups and obturated with AH-Plus, GuttaFlow, and RealSeal using single cone obturation technique. After sectioning longitudinally, apical third of the roots were observed under SEM dentin-sealer-core interface was focused. Marginal adaptation and interfacial gaps at core-sealer interface of all the samples were evaluated and analyzed statistically in this part of the article.
Statistical Analysis Used: Analysis of variance and Tukey's test.
Results: Mean average gap was significantly higher ( < 0.05) for AH-Plus (15.65 ± 10.48 μm), when compared to GuttaFlow (3.51 ± 1.81 μm) and RealSeal (6.01 ± 2.51 μm). Between RealSeal and GuttaFlow, the latter showed least marginal gap; however, this difference was not statistically significant ( > 0.05).
Conclusions: GuttaFlow is better adapted in the apical third of root canals among 3 sealers.

Patterns of Care in Adjuvant Radiation Therapy for Stage II Endometrioid Endometrial Adenocarcinoma: A National Cancer Database Analysis.

Department of Radiation Oncology, Huntsman Cancer Institute, University of Utah, Salt Lake City, Utah.
Purpose: Treating stage II endometrial cancer involves total hysterectomy, bilateral salpingo-oophorectomy, and risk-adapted adjuvant therapy. Professional guidelines support various adjuvant treatments, but high-level data supporting specific options are conflicting. We sought to evaluate adjuvant radiation therapy (RT) trends for these patients, hypothesizing increased utilization of pelvic external beam RT (EBRT) over time.

Background: Minimally invasive dentistry is now becoming the forefront of restorative dentistry, involving less traumatic treatment protocols, conservation of tooth structure and surrounding tissues, enhancing the long-term survivability of treated teeth, and improving the overall quality of life for patients.
Objective: The current case report was conducted to evaluate acquiring deep subgingival interproximal carious lesions by the mean of thermacut bur gingivectomy, in terms of patient satisfaction through pain evaluation, Bleeding on Probing, Pocket Depth, Crestal Bone Level evaluation, and restoration evaluation using modified USPHS criteria.
Material And Methods: A patient with a deep proximal cavity in the posterior tooth was thoroughly examined and underwent Thermacut Bur Gingivectomy (TBG) after caries removal followed by direct resin composite restoration of the prepared cavity.
Immigration of medical personnel from Ukraine to Poland - Context, regulations, and trends.

Background: The migration of healthcare professionals is common phenomenon and shows upwards trends. Poland, which used to be a source country with marginal immigration, has in the past few years received more immigrants due to the simplified access to the labour market for professionals from outside the European Union. We aimed to analyse the immigration of healthcare workforce to Poland with an emphasis on legislative changes regarding the right to practice of medical personnel from outside the EU (mainly from Ukraine).
