To ensure the long-term success of root canal treatment, it is essential to access, clean, and fill all of the canal spaces. However, the anatomic complexities and variations are constant challenges for successful endodontic therapy.1 The morphology of the maxillary first molar has been extensively studied and reported in the literature. Studies have revealed a high incidence of double canal sy...
introduction: the complexity of the root canal system presents a challenge for the practitioner. this systematic review evaluated the papers published in the field of root canal anatomy and configuration of the root canal system in permanent maxillary second molars. methods and materials: all articles related to the root morphology and root canal anatomy of the permanent maxillary second molars...
An investigation on the percentage of two root canals in the distal lower first molars using staining – section method (In- vitro) Dr. H. Razmi *- Dr. H. Hooshyar ** *- Associate Professor of Endodontics Dept.-Faculty of Dentistry – Tehran University of Medical Sciences. ** - Dentist. Background and Aim: The number of roots, the number and configuration of root canals in distal root of lower fi...
1. The infected root canal space cannot be cleaned and disinfected with the standard root canal protocol using an aggressive procedure with endodontic files. 2. After the disinfecting phase of treatment has been completed, filling the root canal is difficult because the open apex provides no barrier for containing the root filling material without impinging on periodontal tissues. 3. Even after...
an accurate diagnosis of the morphology of the root canal system is a pre-requisite for successful root canal treatment. frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have anatomical variations or additional root canals. in this report a maxillary lateral incisor with two roots has been described.
introduction: first branchial cleft anomalies manifest with duplication of the external auditory canal. case report: this report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. external auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and...
Background and Aim: Maintaining the original central canal path during cleaning and shaping of the root canal system plays an important role in the success of endodontic treatment. This study sought to compare canal transportation and centering ability of WaveOne and SafeSider rotary files using cone-beam computed tomography (CBCT). Materials and Methods: This in-vitro, experimental study was ...
AIM The purpose of this in vitro study was to analyze the antimicrobial activity of root canal sealers by using the agar diffusion test (ADT). METHODS AND MATERIALS Three categories of root canal sealers were included in the study: resin-based sealers (4), zinc oxide-based sealers (3), and calcium hydroxide-based sealers (2). The microbial strains used were: S. aureus (2 strains), C. albicans...
INTRODUCTION This study investigated the accuracy of cone-beam computed tomography (CBCT), peripheral quantitative computed tomography (pQCT), spiral computed tomography (SCT), plain (plain digi), and contrast medium-enhanced digital radiographs (contrast digi) in studying root canal morphology. METHODS The root canal anatomy was analyzed in 95 teeth using CBCT, pQCT, SCT, plain digi, and con...
INTRODUCTION We investigated the root canal configuration of maxillary premolars in a Spanish population by using cone-beam computed tomography. METHODS Images of 804 maxillary first and second premolars were obtained from 620 patients who underwent cone-beam computed tomography scanning during preoperative assessment (before implant surgery, orthodontic treatment, dentoalveolar trauma diagno...
