This article aims to report a unique case with aberrant root canal anatomy exhibiting "Y-" and "J"-shaped canal pattern in a mandibular second molar. Anatomic complexities may pose challenges for endodontic treatment. Before performing endodontic treatment, the clinician should be aware of the internal anatomy of the tooth being treated and should recognize anatomic aberrations if present. Pres...

Anatomical complexity can play a critical role in the success of endodontic therapy therefore anatomical landmarks need to be identified and detected at earliest treated. The objective study was ascertain factors that success. Teeth with complex anatomy like dens invaginatus, C-shaped root canal, additional roots, taurodontism are some more common complications may hinder proper treatment. use ...

root canal anatomy diversity and aberrations are common especially in permanent dentition. a thorough understanding of the basic root canal anatomy and its diversities are necessary for successful endodontic treatment. mandibular second premolars are usually single-rooted and have one root canal. incidence of three separate root canals in this tooth is quite rare and taurodontism with three sep...

BACKGROUND AND AIM: Isthmuses are narrow and strip shaped connections between two canals containing pulpal tissue that may encompass bacteria as well. They are hardly accessible for cleaning; therefore, success and failure of root canal treatments could be affected by their presence. The present study was carried out aiming to evaluate the incidence, location, and type of isthmus in mandibular ...

This study evaluated the effect of a) pontic materials and b) occlusal morphologies on the fracture resistance of fi ber-reinforced composite (FRC) inlay-retained fixed dental prostheses (FDP). Inlay-retained FRC FPDs (N=45, n=9) were constructed using a) resin composite (deep anatomy), b) natural tooth, c) acrylic denture tooth, d) porcelain denture tooth and e) resin composite (shallow anatom...

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...

PURPOSE This study aimed to investigate the clinical anatomy of lower premolar roots in a Spanish population by using cone-beam computed tomography (CBCT), correlating findings with patient gender and tooth type. MATERIALS AND METHODS Using 70 CBCT images, we evaluated 126 healthy, untreated, well-developed lower premolars. The number and morphology of roots and root canals, and the foramina ...

Dens invaginatus is a tooth malformation resulting from an infolding of the dental papilla at the time of tooth development. The deep infolding of enamel and dentin are seen in the affected tooth. Maxillary lateral incisors are commonly affected tooth and bilateral occurrence is rare. It shows a broad spectrum of morphologic variations and it usually results in pulpal necrosis. Root canal thera...

a healthy female was referred to endodontic department. the referral letter from her dentist expressed that an emergency pulpotomy of tooth #27 had been carried out with probable perforation of the chamber floor which was due to the unusual anatomy of the chamber. cone-beam computed tomography (cbct) revealed that the tooth had two mesial and two distal canals. perforation site was repaired and...
