introduction: the aim of the present study was to compare the efficacy of 2% lidocaine to 4% articaine in buccal infiltration of maxillary first molars with irreversible pulpitis. moreover, the effect of root length on success of anesthesia irrespective of the type of anesthetic agent was assessed. methods and materials: fifty patients suffering from painful maxillary first molars with irrevers...

Despite the advantages of cone-beam computed tomography (CBCT), the images provided by this diagnostic tool can produce artifacts and compromise accurate diagnostic assessment. This paper describes an endodontic treatment of a maxillary molar where CBCT images suggested the presence of a nonexistent third root canal in the palatal root. An endodontic treatment was performed in a first maxillary...

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...

maxillary second molar with two palatal roots is a rare dental anatomy. the diagnosis and treatment of exceeded root may create challenge for clinicians. the authors discuss the retreatment of a maxillary second molar in which exceeded root was undiagnosed in previous treatment. the case report underlines the importance of complete knowledge about root canal morphology which achieved by careful...

Root canal configuration is an important subject in endodontic practice and dentists should be familiar with all possible types of root canal configuration. A forty-three year old male was referred for root canal treatment of his maxillary left second molar tooth with symptomatic irreversible pulpitis. Pre-operative radiographs showed a three rooted molar. However, after access cavity preparati...

BACKGROUND AND OBJECTIVE Successful root-coverage treatment depends on the thickness of the donor tissue. This study aimed to evaluate the thickness of donor tissue after augmentation of the connective tissue in the palatal area by implantation of lyophilized collagen sponge (Hemospon(®) ). MATERIAL AND METHODS Ten patients with an indication for root coverage, whose palate was deficient in a...

We report a case of nonendodontically treated first upper premolar crown root fracture in which the palatal cusp fracture extended below the cementoenamel junction. Reattachment of the palatal cusp in its original position by acid-etch and flowable composite allowed the creation of a standard access opening as in an intact tooth, avoiding apex location errors and contamination of the root canal...

The endodontic treatment of maxillary molar with an aberrant root canal morphology can be diagnostically and technically challenging.1 Unusual root canal morphology in multirooted teeth is a constant challenge for diagnosis and successful endodontic treatment. Presence of extra canals, lateral canals, deltas is commonly encountered.2 This case report is presented to illustrate and describe the ...

successful endodontic treatment requires thorough knowledge regarding each root canal system of any tooth and probability of extra canals should be considered. second maxillary molar with two palatal root canals is not frequent and its incidence reported in literatures is about 0.4–2%. the present case report describes non-surgical retreatment of maxillary second molar with two palatal root can...
