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.

Abstract Background Mandibular premolars demonstrate high variability in root canal morphology, especially mandibular first premolars. The purposes of this study were to determine the prevalence of root canal configurations of mandibular premolars according to Vertucci classification in a Thai population. Methods Total of 1159 CBCT images of Thai patients who received radiographic imaging at the Department of Radiology, Faculty of Dentistry, Chulalongkorn University in 2017–2018 was evaluated. The data were reported using descriptive statistics and the relationship between the prevalence of the root canal complexities and sex was analyzed using the chi-squared test. Results The most common root canal configuration was Vertucci type I, with a 63.1% and 98% prevalence in the mandibular first and second premolars, respectively. More than 98% of mandibular premolars had a single root. The prevalence of a bifurcation was 28.5% and 1.5% in the mandibular first and second premolars, respectively. The prevalence of a trifurcation was 3.2% in the mandibular first premolar. A C-shaped root canal was observed at 23.7% and 0.7% in the mandibular first and second premolars, respectively. The level of branching was mostly found at the middle 1/3 of the root. Bilateral appearance of the same root canal configuration was identified in 80.3% and 95.9% in the mandibular first and second premolars, respectively. There was no relationship between sex and the prevalence of a bifurcation, trifurcation, or C-shaped root canal. Conclusion Mandibular first premolars have more root canal complexities than mandibular second premolars. Horizontal tube shift x-ray technique, CBCT, dental operating microscope, and knowledge of root canal configurations have an important role in root canal identification in mandibular premolar with suspected complex root canal morphology.

ABSTRACT Tooth resorption is a condition associated with either a physiologic or a pathologic process resulting in a loss of dentin, cementum, and/or bone. Inflammatory process is initiated when the predentin or precemental layer of the tooth is damaged. Resorption can either be external or internal in form. In order to control the tooth resorption, it is necessary to treat the root canal by removing all the pulp tissue. Due to varied root canal morphology, root canal treatment poses a challenge for the clinician. In such cases a combination of conventional lateral compaction and thermoplasticized gutta percha can enable the three-dimensional obturation of the canal space. This case report describes a nonsurgical mode of management of a tooth having internal and external (surface) resorption. How to cite this article Anilkumar A, Nair KR, Nazar F, Rajendran R.

Location, thorough debridement and disinfection and three-dimensional obturation of all the canals in the root of a diseased tooth normally ensure success of the endodontic therapy. Presented is the case of nonsurgical endodontic therapy of mandibular second premolar with aberrant root canal morphology. Keywords: Mandibular second premolar, aberrant root canal morphology, endodontic success.

Aim : To investigate the number and. patterns of. root canals. of mandibular. first. molars.. Methods.: Descriptive observational study to investigate the canal morphology using clearing technique. The duration of the study was one year from 1st February 2020 to 1st February 2021.Non purposive sampling technique was used and 200 mandibular first molar were collected. Data collected was analysed using the SPSS Vr 10. Study variables include Number and pattern of the roots in mandibular teeth. Descriptive statistics were used; frequencies of the root canals and their canal pattern were calculated. Results: In the mesial root, 14 teeth had a one root canal,186 possessed double root canals were observed. Distal root of 160 teeth possessed one canal, 40 teeth possessed two root canals with type 1 pattern mostly observed. Conclusion: Like other populations Pakistani population may have a diverse root canal system in the mandibular molars that ultimately affect endodontic therapy.

Basic Prerequisite

Success of endodontic therapy depends on the proper identification of all the canals, thorough chemo-mechanical preparation followed by three dimensional obturation with fluid tight seal. Failure of any of these steps may occur due to unusual tooth morphology. Proper knowledge of root canal anatomy is a basic prerequisite for the endodontic treatment successful. Mandibular molars may have an additional root located lingually (radix entomolaris) or buccally (radix paramolaris). Awareness and understanding of the presence of unusual external and internal root canal morphology contributes to the successful outcome of the root canal treatment.Bangladesh Journal of Dental Research and Education Vol.5(2) 2015: 66-69
