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...

INTRODUCTION Many reciprocating file systems (RFs) have recently been introduced. This article reviews the properties, effectiveness, and clinical outcomes of the RFs. METHODS A PubMed electronic search was conducted by using appropriate key words to identify investigations on RFs. After retrieving the full-text relevant articles, the cross citations were also identified. RESULTS This revie...

OBJECTIVE The aim of this study is to analyze the effects of combining cone beam computed tomography (CBCT) technology with visual root canal recurrence in the treatment of elderly patients with dental pulp disease. PATIENTS AND METHODS 56 cases of elderly patients with dental pulp disease were contiguously selected, and randomly divided into the control group (70 teeth from 27 patients) and ...

The aim of this study was to evaluate the effectiveness of gutta-percha and Resilon in filling lateral root canals by using the Obtura II system. Root canals of artificial teeth were prepared using a standard protocol, and lateral canals were made in three thirds of the root canal. The root canals were filled with either Obtura gutta-percha (OB), Endo-points flow gutta-percha (ED), or Resilon (...

Mandibular premolars are known for their aberrant root canal variations. This is because, they are highly unpredictable and often present with a wide variety of morphological variations. Slowey et al. reported that these root canal aberrations in mandibular premolars present an endodontic challenge to the dental practitioners.Hence, these teeth may require skillful and careful root canal prepar...

BACKGROUND To determine the prevalence of periapical lesions in root canal-treated teeth in a rural, male adult, Turkish population and to investigate the influence of the quality of root canal fillings on prevalence of periapical lesions. METHODS The sample for this cross-sectional study consisted of 552 adult male patients, 18-32 years of age, presenting consecutively as new patients seekin...

Procedure Following nonsurgical root canal treatment, a post space is created in the root canal by careful removal of the coronal canal obturating material. A sufficient amount of material must be retained in the apical portion of the canal to maintain an adequate apical seal. A custom or proprietary post is fitted and cemented into the root canal for core retention. The post should be passivel...

There is overwhelming evidence that endodontic diseases can be characterized as infectious diseases. There is no longer any question that microorganisms are at the center of the etiological causes of pulpal and periradicular pathological processes (1, 2). There are many secondary reasons contributing to tissue breakdown and endodontic failures, such as root perforations, instrument fractures, e...
