The awareness of internal dental morphology is an excessively critical step in management of endodontic therapy. [1] The mandibular first molar, the earliest permanent tooth to erupt is assumed to be the tooth that mostly creates need for root canal treatment. The most common root canal morphology of the mandibular first molar is the presence of two canals in the mesial root and one or two cana...

Dens invaginatus (DI) is associated with complex internal anatomy. This article represents a maxillary lateral incisor with 5 root canals including DI. The treatment was planned and performed using cone-beam computed tomographic (CBCT) imaging. After clinical and radiographic evaluations, tooth #7 was diagnosed with DI and pulp necrosis with symptomatic apical periodontitis. Periapical radiogra...

the vast majority of mandibular second molars have two roots with three root canals; however, variations in molar root canal anatomy are not uncommon. to the best of our knowledge, four rooted mandibular second molar with three mesial roots and one distal root has never been reported. herein, we present the endodontic management of a four rooted mandibular second molar tooth, diagnosed with the...

A thorough knowledge of root canal morphology is a prerequisite for the endodontic therapy. The maxillary molars, especially the second molars, have the most complicated root canal system in permanent dentition. There are many variations in canal number and configuration in maxillary molars. Treatment may be unsuccessful because the dentist may fail to recognize the unusual canal configuration....

An accurate diagnosis of the morphology of the root canal system is a prerequisite for successful root canal treatment.1 Frequently, root canals are left untreated because the clinicians fail to identify their presence, particularly in teeth that have an anatomical variations or additional root canals.2 Supernumerary root is a developmental condition and may involve any tooth. The incidence of ...

The maxillary first premolar is the most commonly bi- rooted tooth with occasional presentation of three roots system; it is a transitional tooth between incisors and molars. Although it usually has two canals, it may rarely have three and this third canal can easily be missed. Thus meticulous knowledge of tooth morphology, careful interpretation of angled radiographs, proper access cavity prep...

background successful endodontic treatment is dependent on the knowledge of root canal anatomy. objectives this study aims to investigate the root canal anatomy of mandibular first molars in an iranian population. materials and methods one hundred human mandibular first molars were collected and stored in 5.25% naocl. radiographic images of the teeth were taken in mesial, distal, and buccal asp...

The vast majority of mandibular second molars have two roots with three root canals; however, variations in molar root canal anatomy are not uncommon. To the best of our knowledge, four rooted mandibular second molar with three mesial roots and one distal root has never been reported. Herein, we present the endodontic management of a four rooted mandibular second molar tooth, diagnosed with the...

To ensure the long-term success of root canal treatment, it is essential to access, clean, and fill all of the canal spaces. However, the anatomic complexities and variations are constant challenges for successful endodontic therapy.1 The morphology of the maxillary first molar has been extensively studied and reported in the literature. Studies have revealed a high incidence of double canal sy...
