Abnormal morphology of the root canal may exist in any tooth, even a maxillary central incisor. In this paper we report endodontic treatment for a rare example of a maxillary central incisor with one root and three root canals.

Coronal discoloration of endodontically treated teeth is a challenge in clinical dentistry. This study aimed to compare coronal induced by White Mineral Trioxide Aggregate and Calcium-enriched mixture cement. Fifty single-rooted, unrestored premolar extracted for orthodontic reasons were selected. After access cavity preparation, all the root canals instrumented with MTWO rotary files up #40.6%...

Human mandibular canines do not present an internal anatomy as simple as could be expected; there are such canines with a single root and two canals, two roots or fused roots. The existence of mandibular canines with more than one root canal is a fact that clinicians ought to keep in mind, in order to avoid failure during endodontic treatment. In spite of the low incidence of lower canines with...

Three-dimensional (3D) reconstruction of cone-beam computed tomography (CBCT) scans appears to be a valuable method for assessing pulp canal configuration. The aim of this report is to describe endodontic treatment of a mandibular second premolar with aberrant pulp canal morphology detected by CBCT and confirmed by 3D modeling. An accessory canal was suspected during endodontic treatment of the...

Maxillary first premolar is most commonly a bi-rooted tooth, occasionally having three roots. It usually has two canals, but may rarely have three, which can easily be missed, demanding more attention during endodontic intervention. This paper reports this rarity of 3 roots and canals in maxillary premolar, highlighting the difficulties special care needed treatment. Careful investigation diagn...

Knowledge of the size, morphology, and variation of the root canals of a primary tooth is useful in visualizing the pulp cavity during treatment. The roots of the primary teeth are formed completely approximately 16 to 20 months following eruption.1 In approximately three years the roots begin to resorb at the apex or on a lateral surface near the apex.2 The form and shape of the root canals ro...

AIM To evaluate whether objective data could be obtained regarding internal pressure conditions of a molar tooth with canals prepared but not filled exposed to reduced barometric pressures that could be experienced by aircrew. METHODOLOGY The root canals of five mandibular molars were prepared but not filled. Root apices were sealed with a resin-modified glass-ionomer liner and root surfaces ...

Objectives: The aim of this literature review was to analyze the root canal shape of human teeth described in anatomical studies as recent wide use of fiber posts resulted in a new interest for the anatomy of coronal and middle portions of the canal, where post-space should be prepared, in order to achieve the best fiber post fitting to the post-space. Material and methods Original scientific p...

The aim of this study was to evaluate the remaining dentine/cementum thickness using Gates-Glidden burs in serial and crown-down sequences and to observe which of the two sequences is the safest for preparing mesial roots of molars. Thirty-six left and right human mandibular first molars were selected. Standard access cavities were made and initially explored with Flexofiles sizes 10 and 15 unt...

This paper presents a case report of a left mandibular second premolar with three canals and three different apical foramina. A 39-year-old male patient presented to our clinic with pain in the mandibular left second premolar. Initially, pain was caused by cold stimulus and later was spontaneously. The intraoral clinical examination revealed a fractured amalgam restoration with occlusal caries....
