introduction: the purpose of this in vitro study was to evaluate the sealing ability of the readymade temporary filling and hand mixed materials by assessing coronal microleakage. materials & methods: standardized access cavities were prepared in 80 intact human permanent premolar teeth. they were divided randomly into four experimental groups (n=20). the teeth were restored using one of the te...

Introduction: Mineral trioxide aggregate (MTA) has a variety of possible uses, including root-end filling material due to its excellent sealing ability in the presence of moisture and a high degree of biocompatibility. Aim: This case report demonstrates the use of MTA as an obturating material to promote periapical healing of root canals with large apical rarefactions. Materials and Methods: An...

OBJECTIVES To determine whether there are differences in pressure and flow measurements between conventional cystometry (CONV) and ambulatory urodynamic monitoring (AMB) in women with overactive bladder syndrome and urinary incontinence. MATERIALS AND METHODS Retrospective study which included female subjects who underwent both CONV (with saline filling medium) and AMB, separated by less than...

We investigated the interactions between liquid, gas, and solid phases in the capillary filling process of closed-end nanochannels. This paper presents theoretical models without and with absorption and diffusion of gas molecules in the liquid. Capillary filling experiments were carried out in closed-end silicon nanochannels with different lengths. The theoretical and measured characteristics o...

Background: Surgical endodontic therapy is the prescribed treatment of choice whenever the non-surgical options fail which includes the use of a root end filling material. E. faecalis is the most prevalent organism associated with the treatment failed cases Aim: The purpose of the present study was to evaluate and compare the antimicrobial efficacy of Biodentine and MTA as root end filling mate...

Purpose: To investigate the periapical tissue response after root end filling with intermediate restorative material (IRM) and filling of the root-end resection bone defects with autogenous bone or a bone graft substitute in comparison to empty controls. Materials and Methods: Vital roots of the second, third and fourth mandibular premolars in six healthy mongrel dogs were apectomized. The root...

INTRODUCTION After endodontic surgery, radiographic assessment is the method of choice to monitor bone defect healing. Cone-beam computed tomography scans are useful to check and identify the reasons of failure of surgical intervention or confirm healing; however, the artifact generated by some root-end filling material might compromise this task. The objective of the study was to compare the a...
