We investigated in vivo changes in Schlemm's canal and the trabecular meshwork in eyes with primary open angle glaucoma (POAG). Relationships between Schlemm's canal diameter, trabecular meshwork thickness, and intraocular pressure (IOP) were examined. Forty POAG patients and 40 normal individuals underwent 80-MHz Ultrasound Biomicroscopy examinations. The Schlemm's canal and trabecular meshwor...

BACKGROUND Complete mechanical preparation of the root canal system is rarely achieved. Therefore, the purpose of this study was to evaluate and compare the root canal shaping efficacy of ProTaper rotary files and standard stainless steel K-files using micro-computed tomography. MATERIAL AND METHODS Sixty extracted upper second premolars were selected and divided into 2 groups of 30 teeth eac...

AIM To investigate differences in the root canal morphology of permanent mandibular molar teeth at various ages. METHODOLOGY Four hundred and eighty permanent mandibular first and second molars were examined. First and second molars were divided into six and five groups, respectively, according to the age of the patient at the time of extraction. Root canal morphology was studied using a clea...

OBJECTIVES The purpose of this study was to examine the location and accessibility of the second mesibuccal canal in maxillary first molar of a Turkish sub-population. METHODS Presence and accessibility of the MB2 canal in 110 extracted maxillary first molars was examined with unaided vision, dental loups and the DOM. To characterize the geometrical location of MB2 canals, photographs of pulp...

Meticulous cleaning, shaping and filling of the root canal system are requisites for a successful root canal treatment.. Unfortunately, canal preparation is adversely influenced by the highly complex, intricate and variable root-canal anatomy. Thorough knowledge of root canal morphology and unusual anatomy of the tooth is crucial for the practitioner. Over the years, there have been numerous st...

objectives: precise radiographic assessment of the nasopalatine canal is required to prevent implant failure. the purpose of the current study was to determine the three dimensional (3d) morphology, as well as the dimensions of the nasopalatine canal using cone beam computed tomography (cbct). materials and methods: in this descriptive cross-sectional study, maxillary cbct images from 300 patie...

Abstract: Human maxillary first molars are usually considered as three-rooted teeth with four root canals for the presence of a second canal in the Mesio Buccal root (MB2). In addition, lateral ramifications and apical delta of the root canal system may frequently occur, increasing the probability of leaving untreated spaces after the root canal therapy. A thorough knowledge of root canal mor...

INTRODUCTION The type of endoscopic approach chosen for vidian neurectomy can be specified by evaluating the vidian canal and the surrounding sphenoid sinus structures. OBJECTIVE The variations and morphometry of the vidian canal were investigated, focusing on the functional correlations between them which are crucial anatomical landmarks for preoperative planning. METHODS This study was pe...

Root canal filling materials, including sealercement and obturation points or cones, are used in root canal treatment to occlude the apical portion of the canal. These will block the dentinal tubules preventing passage of tissue fluids, toxins, and microorganisms into the root canal space. Many investigators have demonstrated the importance of a sealer cement for effective root canal obturation...
