The purpose of this study was to compare the apical sealing of root canals obturated with different techniques. One hundred-six human mandibular incisors were submitted to instrumentation by means of the step-back technique. After instrumentation, one hundred teeth received an impermeable coating on the external surfaces of the crown and root (except for the area nearby the apical foramen). Aft...

This communication presents the treatment of 15 cases of c-shaped canals in molars and their treatment outcome with two different obturation methods. The data from 901 patients who received root canal treatment in a molar tooth were examined regarding c-shaped root canals, their treatment and their status one year post op. Among the 901 cases, 15 molars had a c-shaped root canal morphology (1,6...

Root fractures are relatively uncommon among other dental traumas and mostly affect the anterior dentition. This case report presents the endodontic and prosthodontic management of a maxillary central incisor with a combined fracture in the middle third of the root and the crown, as well as the 7-year follow up of the case. The healing potential of a horizontal root fracture in the middle third...

Aims The success of endodontic therapy is given by total obturation of the root canal in all dimensions. Thus is become necessary to create a fluid-tight seal able to prevent ingress of bacteria and their toxins [1]. Gutta-percha is the most common root filling material in use today [2] and in this study it was utilized in association with Thermafil system (Maillefer, Switzerland) technique. Be...

Purpose This study was performed to quantify the repeat rate of imaging acquisitions based on different clinical examinations, and to assess the prevalence of error types in intraoral bitewing and periapical imaging using a digital complementary metal-oxide-semiconductor (CMOS) intraoral sensor. Materials and Methods A total of 8,030 intraoral images were retrospectively collected from 3 grou...

OBJECTIVE To compare the long-term sealing ability of GuttaFlow® using different obturation techniques. STUDY DESIGN Three hundred teeth, prepared with a crown-down technique, were divided into thirty experimental groups (n=10) to evaluate the apical and coronal leakage, at 3, 30 and 120 days, of lateral compaction gutta-percha+AH Plus TM, lateral compaction gutta-percha+GuttaFlow®, single co...

CASE REPORT Root canal treatment was performed in a mandibular right second premolar with a periapical lesion and apical resorption. The root canal was prepared with K-files using the step-back technique and 3% NaOCl as an irrigant; during obturation gross overfilling of gutta-percha occurred. The tooth was permanently restored with a post and core along with a crown. Although healing of the pe...

Relevance . Under study is based on the fact that every year number of patients with complicated forms caries increases, in addition, complexity a treatment manipulations, often leads to various errors and complications at all stages endodontic treatment. Aim To evaluate tightness root canal obturation depending selected technique antiseptic canals. Materials methods 40 teeth extracted due chro...

objective: root canal obturation is an important step in endodontic therapy aiming at achieving a complete three-dimensional seal of the canal and preventing microleakage, reentry or growth of microorganisms in the root canal system. several techniques and materials are available for root canal filling. achieving an apical seal is among the most important characteristics of filling materials. t...
