the most difficult clinical considertions in orthograde root canal treatment are generally related to the anatomy of the teeth. three-canalled maxillary and mandibular premolars (mini-molars) have been reported in several studies. the purpose of this paper was to review various aspects of three-canalled premolars including incidence, clinical and radiographic diagnosis, racial predisposition, a...

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.

Maxillary premolars exhibit variable root canal morphology, but it is quite rare to find three canals in their root system. The aim of this case report is to present the diagnosis and clinical management of a patient with anatomical variation of having three root canals in the maxillary first premolar. Three-canalled maxillary premolars are quite an endodontic challenge. A discussion is provide...

INTRODUCTION To achieve success in treatment, one cannot ignore the knowledge of pulp anatomy. Mandibular premolars are considered to be the most difficult teeth for endodontic therapy due to high variability in their canal morphology. It is possible that a relation exists between the crown size and the number of extra canals in these teeth, so this in vitro study aims to investigate the relati...

OBJECTIVE A detailed knowledge of root canal anatomy is a prerequisite for successful endodontic treatment. Such information is highly dependent upon the ethnicity of the population of interest. Lack of sufficient national information concerning internal anatomy can lead clinicians to increase their rate of treatment success. The aim of this study was to evaluate external root morphology and ro...

Thorough knowledge about the root canal variations is essential for the predictable endodontic treatment outcome. The root and root canal anatomy of maxillary first molar varies greatly. A Pub-med literature search about single rooted single canalled maxillary first molar was done to know its details such as incidence, diagnostic method used, age, sex and ethnic background of patient. This arti...

Aim Compare efficacy of Dual Rinse HEDP with sodium hypochlorite to in combination a finishing rinse 17% EDTA solution remove the smear layer. Materials and methods Sixteen human maxillary single-rooted, single canalled sound premolars were used. Specimens distributed into 2 groups labeled according irrigation protocol Each group consisted 8 specimens: Group 1 50% NaOCl followed by EDTA. The Ri...

INTRODUCTION Understanding the internal anatomy of root canal system can significantly influence outcomes of root canal treatment. The aim of this in vitro study was to measure the thickness of mesiobuccal root at different levels in maxillary first molars. MATERIALS AND METHODS In this cross-sectional study, forty extracted human maxillary first molars were radiographed; accordingly, the mes...
