Effect of different surface treatments on the repair bond strength between aged and new alkasite based restorative material.

Background: This study investigates various surface treatment methods to assess shear bond strength between set Cention N (alkasite-based restorative material) and new alkasite based restorative material. Assessing different surface treatments provide insights in optimizing repair procedure that enables durability of the restoration, thus potentially benefitting clinical outcomes.

Methods: A total of 48 alkasite based restorative material blocks, measuring 4 mm in depth and 4 mm in diameter, were prepared.

Effect of in-office bleaching agent on the surface roughness and microhardness of nanofilled and nanohybrid composite resins.

: To compare the surface roughness and microhardness of Ceram.x® SphereTEC™ one and Filtek Z350 XT after in-office bleaching with Pola office. : Twenty samples each of (10 mm diameter and 2 mm height) Ceram.

Survival of human periodontal ligament fibroblast cells in Cornisol and HBSS for transportation of avulsed teeth: a comparative study.

Objective: Viability of periodontal ligament fibroblast cells (PDFC) is one of the key factors in determining the success of replantation of avulsed teeth. Extra-oral time and transport media are closely related to the same. The present study aims to evaluate and compare the efficiency of Cornisol, Hank's balanced salt solution (HBSS) and normal saline in preserving the viability of PDFC.

Comparative evaluation of the accuracy of two electronic apex locators in determining the working length in teeth with simulated apical root resorption: An in vitro study.

Introduction: Accurate determination of working length (WL) is a critical factor for endodontic success. This is commonly achieved using an apex locator which is influenced by the presence or absence of the apical constriction. Hence, this study was done to compare the accuracy of two generations of apex locators in teeth with simulated apical root resorption.
