Hydroxyapatite (HA) is the most thermodynamically synthetic calcium phosphate cement, and has indicated useful as a sealer because can seal a furcation perforation, is shown to be biocompatible and also has potential to promote the healing of bone in endodontic therapy. The objective of this study is to determine the sealing ability of HA produced by School of Engineering, Universiti Sains Mala...

AIM To investigate the pattern of routine endodontic practices among Nigerian dentists. MATERIALS AND METHODS This study was a questionnaire-based survey of samples of dentists in the Nigerian cities of Enugu and Benin. The self-administered questionnaire contained 25 close-ended questions with multiple choice options. The data collected included demographic details of respondents, root canal...

Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment protocol. Maxillary second molars are recognized as usually having a single palatal root with a single palatal canal. The incidence of second palatal root in the maxillary second molar is very rare. Two cases are presented in this paper describing the endodontic management of a fou...

AIM To compare systematically the sealing ability provided by four endodontic cements: AH Plus, Pulp Canal Sealer EWT, RoekoSeal and GuttaFlow. METHODOLOGY A sample of 100 human mandibular incisors with oval-shaped canals was selected from an initial sampling of two hundred teeth. The root canals in 80 teeth were prepared and filled by the same operator using the cold lateral compaction techn...

INTRODUCTION An ideal endodontic sealer should adhere firmly both to dentin and to gutta-percha. OBJECTIVE The aim of this study was to evaluate the adhesion of the root canal filling to dentin and gutta-percha using scanning electronic microscopy (SEM). METHODS The sealing ability of endodontic sealers to dentinal walls of the root canal was assessed in recently extracted human single cana...

AIM The aim of this study was to evaluate the inflammatory response to MTA Fillapex, AH Plus, and Pulp Canal Sealer Extensive Work Time (EWT), in a murine bone defect grafting model. MATERIALS AND METHODS Bilateral mandibular critical defects were produced in 45 Wistar rats with a trephine bur#2 and filled with the endodontic sealers. After 7, 14, and 28 days, the rats were euthanized and the...

The main objective of root canal treatment is thorough mechanical and chemical cleansing of the entire pulp space and to provide an intact hermatic seal. A 30 year-old female patient was referred to the Department of Conservative Dentistry and Endodontic with a chief complaint of acute pain in her right lower back tooth. From the clinical and radiographic findings, a diagnosis of symptomatic ir...

statement of problem: adhesion to root canal dentin is one of the necessary characteristics of endodontic sealers. mta fillapex (angelus, londria, pr, brazil) is one of the recently introduced mta-based sealer. only a limited number of studies have evaluated the bonding of this sealer to the dentin, with conflicting results. objectives: the purpose of this study was to evaluate the bond strengt...

This research analyzed the quality of resin-based sealer adaptation after intracanal laser irradiation. Extracted teeth (n = 168) were root canal treated and divided into four groups, according to dentin surface treatment: no laser; Nd:YAG laser (1.5 W, 100 mJ, 15 Hz); diode laser (2.5 W in CW), and Er:YAG laser (1 W, 100 mJ, 10 Hz). The teeth were divided into four subgroups according to the s...

UNLABELLED One of the primary objectives of endodontic treatment of teeth with pulp necrosis is the elimination of microorganisms from the root canal system, as effectively as possible, especially in cases with chronic periapical lesions. AIM The purpose of this study was to analyze the response of the periapical tissue of dogs' teeth with chronic periapical lesions to endodontic treatment pe...
