Introduction: Historically, countless compounds in aqueous solution have been suggested as root canal irrigants. MTAD shows promise as an endodontic irrigant but there are very few studies comparing its antimicrobial effectiveness with NaOCl and Chlorhexidine. Objectives: To compare the antibacterial efficiency of MTAD, 2.5% Sodium Hypochlorite and 2% Chlorhexidine root canal irrigants against ...

OBJECTIVES The aim of this study was to determine the apical surface characteristics and presence of dental cracks in single-rooted premolars, resected 3.0 mm from the root apex, using the Er: YAG laser, tungsten carbide bur, and diamond-coated tip, by scanning electron microscopy (SEM). EXPERIMENTAL DESIGN Thirty single-rooted premolar teeth were collected. The instrumented and obturated tee...

Orangutans are believed to have close biological affinities to humans. Teeth being the hardest tissue provide useful information on primate evolution. Furthermore, knowledge of the pulp chamber and root canal morphology is important for dental treatment. A female Bornean orangutan and a Sumatran male orangutan skull were available for this study. Both of their dentitions, comprising 50 teeth, w...

The aim of the present work was to evaluate the biomechanical behaviour of the periodontal ligament (PDL) with respect to force development with different controlled loading velocities. For this purpose, an in vitro experimental study was performed on 18 minipig jaw segments. Displacements with variable increasing loading time were applied to one premolar crown of each jaw segment into the ling...

INTRODUCTION There have been varied results from studies comparing postendodontic fracture resistance between teeth obturated with Resilon or gutta-percha. This study was performed to evaluate the fracture resistance of roots obturated by using Resilon (RealSeal system) or gutta-percha (with AH Plus sealer). METHODS Eighty extracted human mandibular single-rooted premolars stored in 10% forma...

Statement of problem: A dowel is essential to retain the core in case of severe tooth destruction. However, the placement of a dowel and core may actually weaken teeth and affect their failure pattern depending on their material properties and stress transfer. Purpose: The present study compared the fracture resistance and failure pattern of endodontically treated premolars with different amoun...

Objective: The current study aimed at assessing the induced apical pressure various simulated irrigantflow rates. Materials and Methods: Forty eight freshly extracted single-rooted premolars were decoronatedand prepared to size 30 0.04 taper using HY-Flex CM rotary file system scanned cone-beamcomputed tomography (CBCT). images reconstructed three-dimensional Computer-aideddesign models (CAD) 3...

Aim: To evaluate and compare the efficacy of 3 different materials on remineralization early enamel carious lesions. Materials Methods:80 maxillary single rooted premolars were divided into four groups(n=20). Group 1: Control,Group 2 : Silver diamine fluoride ,Group Nano-hydroxyapatite 4: Self assembling peptide. Each group except control subdivided two subgroups. All demineralized in demineral...

When G is a rooted graph where each edge may independently succeed with probability p, we consider the expected number of vertices in the operational component of G containing the root. This expected value EV (G;p) is a polynomial in p. We present several distinct equivalent formulations of EV (G;p), unifying prior treatments of this topic. We use results on network resilience (introduced by Co...
