The root canal anatomy of mandibular incisors can present a number of variations, including multiple canals. Two case reports are presented to illustrate the serendipitous discovery and successful non-surgical endodontic management of complex canal systems in mandibular incisors. In both cases, all four mandibular incisors had two canals each.

OBJECTIVES An important factor that interferes with the bonding between the root canal wall and resin cement is the root canal sealer remnant. There is controversy about the effect of eugenol-containing sealers on the bond strength between resin cements and fiber post. The aim of this study was to evaluate the effect of the type of endodontic sealer on the bond strength of FRC posts cemented wi...

BACKGROUND To determine the prevalence of periapical lesions in root canal-treated teeth in a rural, male adult, Turkish population and to investigate the influence of the quality of root canal fillings on prevalence of periapical lesions. METHODS The sample for this cross-sectional study consisted of 552 adult male patients, 18-32 years of age, presenting consecutively as new patients seekin...

NTRODUCTION The goals of root canal therapy are to remove infected and necrotic pulpal tissue remnants, shape the root canal system to facilitate irrigation and medication and adequate sealing using obturation materials. 1 Rotary instruments enhance the quality of obturation by providing conical shape to the root canal. Nickle titanium (NiTi) alloy instruments inherent flexibility that allows t...

BACKGROUND AND AIMS It is critical to have a proper knowledge of the normal anatomy of the pulp and its variations for the success of endodontic treatment. The purpose of this study was to investigate variations in the root canal system of maxillary first permanent molars in an Iranian population. MATERIALS AND METHODS In this study, 137 maxillary first molars were decalcified, dye-injected, ...

background: the incidence of dentinal defects may infl uence the outcome of root canal treatment. the aims of this study were to evaluate and compare the incidence of dentinal defects following root canal obturation with two different techniques. materials and methods: a total of 110 mesial roots of human mandibular fi rst molars were selected. twenty-seven roots were left unprepared as negativ...

OBJECTIVES Cone-Beam Computed Tomography is an alternative imaging technique which has been recently introduced in the field of Oral & Maxillofacial Radiology. It has rapidly gained great popularity among clinicians due to its ability to detect lesions and defects of the orofacial region and provide three-dimensional information about them. In the field of Endodontics, CBCT can be a useful tool...

the aim of this study was to report the endodontic management of right maxillary central incisor having two canals with vertucci canal configuration type iv . internal morphology of root canals is variable and often complex. therefore, to achieve a technically satisfactory endodontic outcome, the clinician must have adequate knowledge of the internal canal morphology and its variations in order...

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...

Local wound debridement in the diseased pulp space is the main step in root canal treatment to prevent the tooth from being a source of infection. Successful root canal therapy is always based on the combination of proper instrumentation, irrigation and obturation of the root canal. Of these three essential steps of root canal therapy, irrigation of the root canal is the most important techniqu...
