Successes of endodontic treatment depend on cleaning and shaping of root canal and adequately obturate the prepared root canal space. 1-3 Obturation has historically been achieved with gutta percha and a sealer. The root canal system has many variations in anatomy such as irregularly shaped canals, lateral and accessory canals, anastomoses between canals and a variety of fins. All this leads to...

INTRODUCTION Three-dimensional obturation of the root canal system is the final objective of root canal therapy. Greater penetration of sealer in root dentine lesser will be the voids at the dentine-sealer interface. Hence, analysis of the dentin/sealer interface allows the determination of a filling technique which could obturate the root canals with least gaps and voids. Therefore, the aim of...

Microbes are considered as the primary etiologic agents in endodontic diseases. The ways of reducing these agents are: root canal debridement, antimicrobial irrigants and antibacterial filling materials. But the complexity of the pulp canal system presents a problem for chemo mechanical preparation. One of the factors determining the success of endodontic treatment is the sealing material with ...

Aim: To measure layer thickness of 5 endodontic sealers and evaluate sealer distribution and adaptation of thermafil and sealer within root canals. Material and Methods: 20 single-rooted teeth divided into 5 groups were prepared in the crown-down technique. Smear layer was removed and root canals were obturated with Thermafil and 1 of 5 different endodontic sealers: AH Plus, Tubliseal, Acroseal...

A case of orofacial pain and inferior alveolar nerve (IAN) paraesthesia after extrusion of endodontic sealer within the mandibular canal treated with prednisone and pregabalin is described. A 36-year-old woman underwent root canal treatment of the mandibular second right premolar tooth. Post-operative panoramic radiograph revealed the presence of radiopaque canal sealer in the mandibular canal....

The present study describes a case of endodontic sealer (AH Plus) penetration within and along the mandibular canal from the periapical zone of a lower second molar after endodontic treatment. The clinical manifestations comprised anesthesia of the left side of the lower lip, paresthesia and anesthesia of the gums in the third quadrant, and paresthesia and anesthesia of the left mental nerve, a...

OBJECTIVE To evaluate the discrepancy of root canal filling (RCF) measurements obtained from original root specimens and cone-beam computed tomography (CBCT) images. MATERIAL AND METHODS Seventy-two human maxillary anterior teeth were prepared up to an ISO #50 K-File 1 mm short of the apical foramen. Thus, the teeth were randomly divided into 8 groups, according to the root canal filling mate...

The toxicity of endodontic materials is reviewed. The patient may be exposed by constituents leaching from the unset and set sealer and by accidental overfilling of the root canal. For most patients the exposure is believed to be below the threshold for a toxic effect. Most sealers exhibited a cytotoxic response, especially unset and the responses diminished with time after setting. Unset and n...

We describe the successful use of a combination of nonsurgical root canal treatment and ultrasonic irrigation for collaborative management of a maxillary left lateral incisor with perforation of the apical third of the root. During the endodontic treatment procedure, the ultrasonically activated tip was used for intracanal irrigation. The area of perforation in the apical third of the root and ...

Introduction. Adequate radiopacity of endodontic sealers allows radiographic visualization, assessment root canal filling quality and its clinical follow-up after obturation. The aim our study was to evaluate the Bio-Root RCS, MTA Fillapex, Bioceramic Root Canal Sealer, GuttaFlow Bioseal in comparison AH Plus sealer, as a gold standard practice. Material methods. Sealer specimens, 2 mm thick 5 ...
