familiarity with the normal and abnormal anatomy of the root canal system is essential for successful root canal treatment. the possibility of concomitant three-rooted and three- canalled maxillary and mandibular premolars are extremely rare. the purpose of this paper was to report a case with a three-rooted maxillary first premolar and two three-rooted mandibular premolars.

familiarity with the intricacies and variations of root canal morphology is essential for successful endodontic treatment. maxillary central and lateral incisors are known to be single-rooted with one canal, however, this case report describes endodontic treatment of maxillary central and lateral incisors with two buccopalatal root canals.

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...

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%.

Success of endodontic treatment depends on the proper identi-fication of all the canals, thorough chemomechanical preparation followed by three-dimensional obturation with hermetic seal. Failure of any of these steps may occur due to unusual tooth morphology. Usually mandibular molars have two roots with three canals but in few teeth, the number of roots and canals vary. The variation in the nu...

AIM The aim of this study was to investigate the prevalence of additional canals in maxillary first molars in a selected population in Nigeria. METHODS AND MATERIALS One hundred extracted teeth were collected from the Pedodontic and Oral Surgery clinics of the University College Hospital in Ibadan, Nigeria. The teeth were identified and their root planed to remove adherent soft tissues. Each ...

BACKGROUND Aberrations in the root canal anatomy are clinically challenging for clinicians. Mandibular first molars usually have 2 roots and 3 or 4 canals, but various combinations may exist. A distal root with three canals is rare and its incidence in literature is about 0.2 - 3%. As a diagnostic tool, cone-beam computed tomography (CBCT) may be a better choice for diagnosis of extra roots or ...

Success in root canal treatment is achieved after thorough cleaning, shaping, and obturation of the root canal system. This clinical case describes conventional root canal treatment of an unusual mandibular first molar with six root canals. The prognosis for endodontic treatment in teeth with abnormal morphology is unfavorable if the clinician fails to recognize extra root canals.

The purpose of this study is to demonstrate the importance of knowledge of the internal anatomy of root canals for the success of endodontic treatment. Lack of knowledge of anatomic variations and their characteristics in different teeth has been pointed out as one of the main cause of endodontic therapy failure. Dental operating microscope plays a key role in the identification of canal and su...

The main goal of endodontic treatment is healing of the periapical tissues which are gained by elimination of bacteria and their byproducts from the canal and prevention from reinfection. Understanding of root canal anatomy is an essential part in endodontic treatment. Anatomic forms and variations in special teeth should be well known, one of them is extra roots/ canals. Although possible aber...
