Knowledge of the most common anatomic characteristics and their possible variations is fundamental, because the nontreatment of one canal can lead to endodontic treatment failure.1
The main objective of endodontic therapy is to eliminate infection from the root canal and the prevention of reinfection.2 The achievement of this goal depends on several factors:3
-elimination of surviving microorganisms in the root canal system through effective cleaning and shaping procedures -creation of a tight three-dimensional seal with an inert filling material
-blockage of any communication between the oral cavity and the periradicular tissue through a high quality coronal restoration
However,the variation of pulp cavity morphology, especially in multirooted …show more content…
studied 830 mandibular canines, and reported that 98.3% had only one root and of these 4.9% had two canals and one orifice, 1.2% had two canals and two orifices. Two canals and two roots were present in 1.7% of the cases.25 Hess (1921),26 Barrett(1925),27 Pucci and Rei (1944),28 Madeira et al. (1973),29 De Deuss (1982),30 all have described the case of one root and two canals. Bakianian Vaziri P et al. (2006) analyzed 100 canines and detected the presence of two radicular canals in 12% of the cases using stereomicroscope.31 His results are in accordance with those obtained by Kaffe I et al.(1985),32 who which showed a percentage of 13.75%, in a radiological study on 400 mandibular canines. Green D(1973) reported 13% in the analysis of 100 teeth.33 Pineda F and Kuttler Y (1972) found 18.5% of the mandibular canines having two canals through a study on 187 radiological images.34 Calişkan MK et al. (1995) studied 100 mandibular canines and reported the incidence being 19.5%.35 Holtzman L reported mandibular canine with three root canals.36
The objective of this case report was to describe the clinical management of three teeth with aberrant root canal morphology: a mandibular canine with two radicular canals, maxillary second premolar with three roots and root canals;and maxillary second molar with four roots and root canals,all of which are rare clinical occurrence in our
