Root fracture is defined as a fracture involving the dentin, cementum, and pulp. Most fractures occur in the maxillary anterior teeth between the ages of 11 and 20 years old. The treatment for root fracture in permanent teeth involves the reduction and fixation of the displaced coronal segment. When signs of pulp necrosis or inflammatory root resorption are present, root canal therapy should be...

Recently, several in vitro and in vivo studies demonstrated promising results about the use of photodynamic therapy during root canal system disinfection. However, there is no consensus on a standard protocol for its incorporation during root canal treatment. The purpose of this study was to summarize the results of research on photodynamic therapy in endodontics published in peer-reviewed jour...

Successful root canal therapy requires a thorough knowledge of root anatomy and root canal morphology which may be quiet variable. The significance of internal root canal morphology has been emphasized by studies demonstrating that variations in canal morphology may affect the endodontic outcome. Consequently, in treating each tooth the clinician must assume that complex anatomy occurs often en...

The several anatomical variations existing in the root canal system may contribute to failure of the root canal therapy. Knowledge of the internal dental morphology is a complex and extremely important point for planning and performing endodontic therapy. This paper reports the case of a left mandibular third molar that presented only one dental conical root and only one aberrant radicular cana...

Background Schwannomas of the vidian canal are an extremely rare type of intracranial tumor that can have variable clinical presentations including headache, facial pain, facial muscle paralysis, decreased lacrimation, or nasal dryness. We present an atypical case of an incidentally identified asymptomatic vidian canal schwannoma. Case Description A 49-year-old woman with a history of multiple ...

BACKGROUND AND AIM: The aim of this cross-sectional study was to evaluate the knowledge and attitude of school teachers regarding root canal therapy (RCT) in Kerman, Iran. METHODS: 403 teachers participated in this study (49.9% were female and 46.9% were male). Data collection was performed by a researcher-made questionnaire. After checking the validity and reliability of the questionnaire, it ...

Introduction: Feeling pain after root canal therapy has always been a major problem for patients and dentists. One of the suggested methods to manage the pain is using the prophylactic medication before treatment process. This study aimed at investigating the comparison of pretreatment with novafen versus gelofen on reducing the pain after root canal therapy. Materials &Methods: This double-...

The successful outcome of root canal therapy is related to the ability to negotiate the canal to its apical terminus, allowing thorough debridement, disinfection, and obturation of the prepared canal space. In situations in which calcific deposits have blocked access to the canal, treatment efforts are often thwarted. This article describes endodontic management of tooth with calcific metamorph...

This article describes a clinical case of mandibular second premolar with three separated canals in apical third of the root that are diagnosed and endodontically treated. Sound knowledge of root canal anatomy and morphology, tactile examination of canal walls, critical interpretation of radiographs and high magnification examination are essential elements of success in complicated root canal t...
