The awareness of internal dental morphology is an excessively critical step in management of endodontic therapy. [1] The mandibular first molar, the earliest permanent tooth to erupt is assumed to be the tooth that mostly creates need for root canal treatment. The most common root canal morphology of the mandibular first molar is the presence of two canals in the mesial root and one or two cana...

The aim of this study was to evaluate the frequency of roots, root canals and apical foramina in human permanent teeth using cone beam computed tomography (CBCT). CBCT images of 1,400 teeth from database previously evaluated were used to determine the frequency of number of roots, root canals and apical foramina. All teeth were evaluated by preview of the planes sagittal, axial, and coronal. Na...

Aim of this paper was to investigate the particular anatomic features of the endodontic space of third molars in the general population of Croatia. A total of 106 fully developed third molars (56 maxillar and 50 mandibular) has been analyzed. The respective number of roots and of root canals, the structure of the roots, and the curvature and absolute length of the root-canals were analyzed. In ...

OBJECTIVE The study was designed to test application of ultraviolet light to root canal walls, as a mean of complementary immediate disinfection after the use of sodium hypochlorite. STUDY DESIGN Root canals were infected ex vivo with Enterococcus faecalis for 48 hours. Non-attached bacteria were washed away, and the remaining attached bacteria were subjected to disinfection, with 5% sodium h...

Clinicians need to have intimate knowledge and thorough understanding of both pulp chamber and root canal anatomy. They should be aware of possibility of anatomical variations in the root canal system during endodontic treatment. Maxillary canines usually have single root and root canal but rarely may have single root with two root canals. This case describes a lengthier maxillary canine with t...

Precise preparation of the root canal ostium with a view to hermetical closing with retrograde root filling is an important prognostic factor determining the success of the procedure of tooth resection. Root canals interconnected with a narrow isthmus may cause problems both in endodontic treatment and in retrograde filling. The aim of this work is the research of the transverse cross-section o...

Introduction: The main goal of root canal treatment is to prevent or heal formation of apical periodontitis. Complexity of root canal anatomy presents clinical challenges related to treatment outcome. The aim of this study was to investigate the morphology of the root canal system of mandibular 2 nd premolar in north Indian subpopulation using periapical radiographs and CT Dentascan. No such st...

AIM The hypotheses tested in this study were that: (i) Enterococcus faecalis can survive long-term entombment in root filled teeth without additional nutrients, (ii) initial cell density influences the survival of E. faecalis in instrumented root canals and (iii) gelatinase-production capacity influences the survival of E. faecalis in root canals. METHODOLOGY The root canals of 150 extracted ...

introduction: the aim of this in vitro study was to compare the amount of apically extruded debris after root canal preparation using rotary and reciprocating systems in severely curved root canals. methods and materials: thirty six extracted human mandibular first molars with 25-35 ° curvature in their mesiobuccal (mb) canal (according to schneider’s method) were cleaned and shaped with protap...

the presence of three root canals in the distal root of the mandibular fi rst permanent molars is rare; based on in vitro studies its incidence is reported to be between 0.2% and 3%. with the advent of cone beam computed tomography (cbct) as an adjunctive diagnostic aid, the determination of root canal anatomy in teeth with extra canals and complex canal confi gurations has become more precise....
