the main objective of this case report is to present a rare root canal configuration of maxillary molar with seven root canals; three mesiobuccal, two palatal and two distobuccal canals diagnosed during treatment procedure confirmed by spiral computed tomography. a thorough knowledge of root canal morphology, proper clinical and radiographic examination, and use of dental operating microscopes ...

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...

The purpose of this study is to identify schematic relationships between root canal axis, the cementoenamel junction (CEJ), and contour clinical crown’s facial surface in maxillary central incisors. 72 radiographic images extracted incisors with previous treatment were collected. Angles (tangent angle) axis lines tangent fiducial points on 3.5 mm, 4.0 4.5 5.0 5.5 mm cervical incisal edge measur...

Fractured root tips Roots break during extraction even when the most accomplished exodontist is at the helm. What separates the pros from the pretenders is how you handle it when it happens to you. Atomization (pulverization of roots with a bur on a high-speed handpiece), though described in some textbooks, is an imprecise and potentially dangerous way of dealing with stubborn root tips. The au...

Introduction: A single incision palatal harvest technique was applied to minimize the size of the palatal wound and to allow for primary closure of the donor site, which may result in reduced postoperative discomfort. Aim: This case presentation describes the use of a coronally positioned flap with subepithelial connective tissue graft using a single incision technique for the treatment of dent...

AIM To investigate the effects of endodontic treatment, post placement and ceramic restoration type on the fracture resistance of premolars. METHODOLOGY One hundred and twenty teeth maxillary premolars were allocated to four groups (A-D; n = 30). In group A, mesio-occlusal-distal-inlays with a buccal and palatal wall of 2 mm (MOD), in group B partial onlays with palatal cusp coverage and in g...

Anatomical variations in root canal morphology are an enigma and it is this variability, which is often a complicating factor in a successful root canal treatment. To achieve success in endodontic therapy it is imperative that all the canals are located, cleaned and shaped and obturated three dimensionally. Maxillary first premolar having three separate roots has an incidence of 0.5-6%. Even ra...

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...
