Root and Root Canal Morphology of Permanent Mandibular Anterior Teeth in a Sample of Egyptian Population

Abstract

Objectives:The aim of this work was to study the morphology of root and root canals of permanent mandibular anterior teeth in a sample of the Egyptian population.Methods: A total of 16 permanent mandibular central incisors (I1), 25 permanent mandibular lateral incisors (I2) and 15 permanent mandibular canines (C) were collected and classified into groups according to shape and number of roots. Molds of pink wax with the samples were submitted for cone beam computed tomography (CBCT). The number and shapes of roots were determined and types of root canals were assessed and classified according to Vertucci's classification. Finally, data was statistically analyzed.Results: Regarding the macroscopic appearance of I1, all the samples had one root while I2 had one root with 92%. As for C, 80% of the sample was with one root. CBCT revealed the following configurations, according to Vertucci's classification; Regarding I1, Type I was the most common canal configuration (75%) followed by type II (12.5%) and type III (12.5%) Regarding I2, Type I (60%) was the most common configuration followed by type III (28%). As for C, 66.7% of the sample was represented by type I followed by type III and IV, where each was represented by 13.3%. Conclusions:There are morphological variations in the root and root canal anatomies of the mandibular central incisors, lateral incisors, and canines of Egyptian population as compared to other populations.

Investigation of Root Canal Anatomy of Mandibular Permanent canine in Egyptian Subpopulation: A Cone-Beam Computed Tomography Study

“…Studies on root canal anatomy of mandibular canine in Egyptian population is scarce, one study 43 examined a very small sample size (15 mandibular canines), even though they showed approximated percentage to our study for a second canal 33.3% with 13.3% for Vertucci type III, 13.3% IV and 6.7% V, this sample size cannot reflect a prevalence in a subpopulation. Another study 44 evaluated mandibular anterior teeth bilaterally in 100 patients with contradictory results to the present study as they concluded a 100% for Vertucci type I for mandibular canines with total absence of a second canal 44 , this could be attributed to the sample size which is one tenth of the current study sample size.…”
