Background and Aim: It is essential to know the internal root canal anatomy to reach a successful root canal debridement and a subsequent successful root canal obturation. Due to the importance of knowing the complexity of mid-mesial (MM) canals and isthmuses and how to deal with these anatomic variations, in this study, we examined the incidence and prevalence of the MM canal and isthmuses in ...

Accurate diagnosis of the root canal morphology and anatomy is essential for thorough shaping and cleaning of the entire root canal system and consequent successful treatment. This report describes a case of maxillary second premolar with two roots and three root canals (two mesial and distal palatal canals). The case report underlines the importance of complete knowledge about root canal morph...

the main objective of endodontic therapy is the thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material. failure to find and fill a canal contributes toward the failure of endodontic therapy .the root canal anatomy of mandibular first molars is complex. studies of the morphologic structure of root canal systems have d...

The mandibular first molars ( primary and permanent) usually have 2 roots located mesially and distally, but occasionally they have an additional root located distolingually requiring special attention when root canal treatment is being considered . The additional root is regarded as a normal racial and morphological variation rather than as an abnormality. It appears to be more common in races...

AIM To describe the successful non-surgical endodontic management of a permanent maxillary lateral incisor tooth with four root canals. SUMMARY Aberrant morphology of root canals can occur in any tooth, including maxillary lateral incisors. In the presented case, clinical examination and radiographs clearly depicted the presence of four root canals in a right maxillary lateral incisor. The di...

AIM A case of unusual Root morphology is presented to demonstrate anatomic variations in mandibular third molar. BACKGROUND The most common configuration of mandibular third molar is two Roots and three canals; however they may have many different combinations. Endodontic treatment was performed in mandibular third molar having aberrant anatomy. CASE DESCRIPTION Four Root canal orifices wer...

Understanding the morphological anatomy of the root and root canal systems of the teeth increases the success rate of endodontic therapy. Advanced diagnostic imaging techniques like cone beam computed tomography (CBCT) are an essential aid in understanding the anatomy of teeth especially in mandibular premolars. Most commonly mandibular first and second premolars have a single root and a single...

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...

The mesiobuccal root of the maxillary molars is well known to pose a hindrance during endodontic therapy. Presented here is a case of a maxillary left second molar where three canals were located in its mesiobuccal root with the use of visual and diagnostic aids. Difficulties encountered during the process of unveiling the tooth's internal anatomy were discussed. The dilemmas encountered pertai...

Nonsurgical endodontic therapy of a right maxillary first molar with three roots and seven root canals. This unusual morphology was diagnosed using a dental operating microscope (DOM) and confirmed with the help of cone-beam computed tomography (CBCT) images. CBCT axial images showed that both the palatal and distobuccal root have a Vertucci type II canal pattern, whereas the mesiobuccal root s...
