Abstract:Successful treatment of any case mainly depends on proper diagnosis; this is particularly true when we are doing an endodontic treatment. Internal anatomy of root canal system varies a lot and predisposes to inadequate root canal preparation and should be recognized before or during treatment. Proper knowledge of these anatomical variations and proper diagnosis are of paramost important. As the routine diagnostic aids, radiograph is a two dimensional representation of a three dimensional object where the internal anatomy of the tooth cannot be appreciated properly. Spiral computed tomography (SCT) has got an advantage as it gives a 3 dimensional image of a given object. We present an interesting case of multiple canals in all the teeth except incisors in a single patient which was diagnosed with the aid of Dental CT and its potential role, this diagnostic method can help in the field of endodontics

Root Canal System

To report a case of endodontic treatment of a maxillary canine in which an extra canal was located and successfully treated. Endodontic therapy is essentially a micro neurologic surgical procedure involving complete debridement and three dimensional obturation of the root canal system to obtain a fluid impervious seal. The foundation of the procedure is based on the intimate knowledge and thorough understanding of the anatomy of both the pulp chamber and the root-canal system. A tooth exhibit variations in their root canal anatomy and poses a challenge in diagnosis and treatment. In the teeth particularly with additional root canals or anatomical variations, root canals are often left untreated and that would be the main reason for unfavourable outcome of the treatment. Maxillary canine are statistically more commonly single rooted, single canal but rarely may have single root with two root canals.Journal of Universal College of Medical Sciences, Vol. 5, No. 2, 2017, Page: 53-56

Mandibular First Molar

ABSTRACT The knowledge of root canal morphology and the existing anatomical variations is essential for successful endodontic therapy. This report presents an extraordinary case of unusual tooth morphology involving the mandibular first molar with a single root and a single canal in a patient. Endodontic treatment of the affected tooth 36 was performed. Cone beam computed tomography (CBCT) images confirmed our diagnostic and therapeutic measures after endodontic management of the teeth. This morphologic variation has been reported once in the literature. The availability of three-dimensional images further provided the opportunity for the precise description of the anatomy of mandibular first molar with single roots and single canals.

Rare Case Report

Abstract Anatomical variations must be considered in clinical practice and proper radiographic evaluation must be done during endodontic treatment. Access cavity modifications may be required for proper assessment of complex root canal anatomy. Higher magnification and illumination can be useful to recognize and locate additjonal canals. This article describes the diagnosis and clinical management of a rare case with type VII root canal anatomy in maxillary second premolar.

The successful outcome of endodontic treatment is dependent on complete cleaning, shaping as well as three dimensional obturation of the root canal system. A conventional radiograph is a two-dimensional replication of a three-dimensional object and does not provide any conclusive evidence for canal curvatures. An accurate knowledge of the tooth anatomy and curvature is essential to avoid procedural errors. 100 freshly extracted human teeth were used in this study. Digital images were obtained using the plywood JIG and Schneider’s technique. These images were analyzed using the VixWin Pro digital image analyzing software (Gendex system). Statistical analysis was done using paired t test. The canal curvature average values measured using Jig method and Schneider method for mandibular teeth are 28.23° (±9.96) and 22.07° (±9.46) respectively. The smallest/largest curvature angles measured using Jig method and Schneider technique are 12/52° and 8/44° respectively. Canal curvature average values measured using Jig method and Schneider method for maxillary teeth were 23.40° (±11.36) and 19.23° (±11.94) respectively. The smallest/largest average curvature angles measured using Jig method, Schneider technique were 9/70° and 5/72° respectively. The values of the canal curvature angle obtained during routine radiographs in clinics have lower curvature angle and higher radius values as compared to the values obtained by this innovative JIG technique. Therefore, a clinician should always keep in mind the difference while measuring the curvature angle on radiographs during root canal treatment.

Considering any finite three-dimensional object, a “projection” is here defined as a two-dimensional representation of the object's mass per unit area on a plane normal to a given projection axis, here taken as they-axis. Since the object can be seen as being built from parallel, thin slices, the relation between object structure and its projection can be reduced by one dimension. It is assumed that an electron microscope equipped with a tilting stage records the projectionWhere the object has a spatial density distribution p(r,ϕ) within a limiting radius taken to be unity, and the stage is tilted by an angle 9 with respect to the x-axis of the recording plane.

Rotating Blade

The biological objectives of root canal treatment have not changed over the recentdecades, but the methods to attain these goals have been greatly modified. Theintroduction of NiTi rotary files represents a major leap in the development ofendodontic instruments, with a wide variety of sophisticated instruments presentlyavailable (1, 2).Whatever their modification or improvement, all of these instruments have onething in common: they consist of a metal core with some type of rotating blade thatmachines the canal with a circular motion using flutes to carry the dentin chips anddebris coronally. Consequently, all rotary NiTi files will machine the root canal to acylindrical bore with a circular cross-section if the clinician applies them in a strictboring manner

Canal Morphology

This study aimed to investigate variations in the root canal morphology of maxillary second premolar (MSP) teeth using microcomputed tomography (micro-CT). Sixty (N = 60) human extracted MSPs were collected and prepared for micro-CT scanning. The duration for scanning a single sample ranged between 30 and 40 min and a three-dimensional (3-D) image was obtained for all the MSPs. The images were evaluated by a single observer who recorded the canal morphology type, number of roots, canal orifices, apical foramina(s), apical delta(s), and accessory canals. The root canal configuration was categorized in agreement with Vertucci’s classification, and any configuration not in agreement with Vertucci’s classification was reported as an “additional canal configuration”. Descriptive statistics (such as mean percentages) were calculated using SPSS software. The most common types agreeing with Vertucci’s classification (in order of highest to lowest incidence) were types I, III, V, VII, II, and VI. The teeth also exhibited four additional configurations that were different from Vertucci’s classification: types 2-3, 1-2-3, 2-1-2-1, and 1-2-1-3. A single root was found in 96.7% and the majority of the samples demonstrated two canals (73.3%). Further, 80% of the teeth showed one canal orifice. The number of apical foramina’s in the teeth was variable, with 56.7% having solitary apical foramen. The accessory canal was found in 33.3%, and apical delta was found in only 20% of the samples. Variable morphology of the MSPs was detected in our study. The canal configuration most prevalent was type 1; however, the results also revealed some additional canal types.
