The key goals of endodontic therapy include the removal of pulp remnants, necrotic tissue, micro-organisms, and microbial byproducts from the root canal system. Although this may be achieved through endodontic preparation, complete removal is difficult because of the intricate root canal anatomy [1]. Isthmi, apical deltas, intercanal communications, and loops are commonly observed in root canal...

accumulation of soft tissue or dentinal remnants in the apical region is a common event that can cause blockage of root canals. this event can be avoided if apical patency is performed during the root canal shaping procedures. however, there is no consensus on the role of apical patency in relation to the success of endodontic treatment of necrotic teeth with apical periodontitis. therefore, th...

objectives: it is essential for clinicians to have adequate knowledge about root canal configurations; although its morphology varies largely in different ethnicities and even in different individuals with the same ethnic background. the current study aims to review the root canal configurations of mesiobuccal roots of maxillary first molars in an iranian population based on different epidemiol...

Anatomic and internal morphology of a root canal system is more complex and differs for each individual tooth of which mandibular premolars have earned the reputation for having aberrant anatomy. The occurrence of three canals with three separate foramina in mandibular second premolars is very rare. A wider knowledge on both clinical and radiological anatomy especially spiral computed tomograph...

The objective of this study was to review the literature with respect to the root and canal systems in the maxillary first molar. Root anatomy studies were divided into laboratory studies (in vitro), clinical root canal system anatomy studies (in vivo) and clinical case reports of anomalies. Over 95% (95.9%) of maxillary first molars had three roots and 3.9% had two roots. The incidence of fusi...

AIM To describe unusual variations in the root morphology and root canal systems of mandibular first and second premolar teeth extracted for orthodontic reasons. SUMMARY Normally mandibular first and second premolar teeth have single roots with single canals. A 15-year-old patient presented for orthodontic treatment and two mandibular premolar teeth were examined post-extraction. The mandibul...

Aim This study aims to investigate the root canal anatomy of human extracted permanent maxillary anterior teeth in patients reporting to our dental institution in Chennai using cone beam computed tomography (CBCT). Materials and Methods A total of 285 maxillary anterior teeth comprising of 100 central incisors, 85 lateral incisors, and 100 canines extracted from various patients reporting to ...

p r r o w t bstract berrations in the root canal anatomy are a commonly ccurring phenomenon. A thorough knowledge of the asic root canal anatomy and its variations is necessary or successful completion of the endodontic treatment. andibular second premolars usually have a single root nd a single root canal. The incidence of three separate oots itself in this tooth is quite rare, and the presenc...

The presence of a missed canal in the course of root canal treatment is one of the common reasons for failure of therapy. The consequence of a missed canal will or may lead to chronic infection and post operative flare ups. Hence, it is very important to explore the morphology of the tooth as well its internal anatomy to overcome failure in endodontic practice. Root canal therapy of maxillary t...

For the successful root canal treatment, thorough cleaning and shaping of the root canal system is a necessary procedure. C-shaped canals are known to have a complex canal anatomy with numerous fins connecting individual canals, thus require supplementary effort to accomplish a successful root canal treatment. Generally, anthropologic differences in tooth shape is not an important issue in the ...
