Cone beam computed tomography evaluation of maxillary molar root canal morphology in a Turkish Cypriot population

Abstract

The aim of this retrospective study was to review, analyse and characterize the root canal morphology of maxillary molars, using cone beam computed tomography (CBCT), in a group of the Turkish Cypriot population. The sample for this cross-sectional study consisted of retrospective evaluation of CBCT scans of 290 adult patients (age range 16À80). The number of roots and their morphology, the number of canals per tooth and the root canal configurations were also classified according to the method of Vertucci. Pearson's chi-square test was performed for canal configurations, sides and gender (p < 0.05). Among the 373 first molars, there was no single-rooted specimen, 2 (0.53%) teeth had 2 roots, 365 (97.8%) teeth had 3 roots and 6 ones (1.6%) had 4 roots. Among the 438 second molars, 14 (3.1%) were single-rooted, 26 (5.9%) teeth had 2 roots, 392 (89.4%) teeth had 3 roots and 6 teeth (1.3%) had 4 roots. No sex difference was found in the frequency of additional canals both in the maxillary first and second molars. Occurrence of additional canals did not differ with age. These results provide detailed knowledge of the root canal anatomy of the maxillary molar teeth in this particular population, which is of clinical importance for dental professionals when performing endodontic treatment.

Morphology of Root Canal System of Maxillary and Mandibular Molars

“…Table 3 shows the number of roots and root canals of maxillary third molar among different populations [41,42,[45][46][47][48][49][50][51]. The most common root canal configuration for maxillary third molar is type I (1-1) followed by type II (2-1) (Table 4) [42,47,50,51]. The incidence of C-shaped canals in this tooth was reported in two studies: in the USA (2.2%) [45] and in China (8.5%) [51].…”

Occurrence and Morphology of MB2 Canals in Maxillary First Molars in an Indian Subpopulation: A Cone Beam Computed Tomography Study

“…Furthermore, studies using the clearing technique or sectioning using a dental operating microscope have shown higher detection rates than radiographic and CBCT examinations. 22 In the present study, canal configurations were identified according to Vertucci's classification system (Graph 2), revealing the most prevalent type as Type II in 83.5%. According to Rwenyonyi et al, type I was the most frequent, accounting up to 75.1 to 100%.…”

Endodontic Retreatment of Maxillary Second Molar with Four Roots

“…In Italy, the frequency of upper second molars with four roots was described with 1.27% ( n = 157) [11]. Comparable results were demonstrated in Greece (1.24%, n = 402) [12], in Cyprus (1.37%, n = 438) [13], and in the Portuguese study mentioned above (1.44%, n = 277) [3]. On the other hand, in East Asia, lower occurrence rates of this rare morphological anomaly were identified in population-based CBCT studies in Thailand (0.22%, n = 457) [9], South Korea (0.49%, n = 820) [14], and China (0.28%, n = 1066 [15]; 0.77%, n = 519 [16]; 0.98%, n = 1226 [17]; and 1.12%, n = 979 [18]).…”
