Evaluation of anatomy and root canal morphology of the maxillary first molar using the cone-beam computed tomography among residents of the moscow region

Abstract

Background:The success of endodontic treatment depends on the knowledge of root canal system. The root canals have complex morphology and wide individual variations. The aim of this study was to evaluate the root canal morphology of the maxillary first molars among residents of the Moscow region using cone-beam computed tomography (CBCT) scanning.Materials and Methods:Three hundred CBCT images of patients aged 20–70 years old were analyzed to study the root canal system (the number of canals and the configuration according to Vertucci's classification) of the maxillary first molars. The prevalence of a second mesiobuccal (MB2) in the mesiobuccal root (MB) was recorded in each age group.Results:three separated roots of the maxillary first molar were observed in 100% of cases. MB2 canals were found in 59.8% of cases. A second distobuccal canal was observed in 0.5% of cases. The canal morphology in the MB root was 40.2% in Type I, 22.4% in Type II, and 37.3% in Type IV.Conclusion:The prevalence of MB2 canals was 59.8%, and the most common canal morphology was Vertucci's Type I. Using CBCT scanning is a useful technique to evaluate and analyze the root canal system.

“…Moreover, they used a similar methodology to determine the molar morphology. However, the proportion of the three roots in the current study was lower than the results of the study conducted in Moscow and Poland, where the prevalence of three roots was 100% (Olczak & Pawlicka, 2017;Razumova et al, 2018).…”

“…The high percentage findings of a researcher also include Khademi et al 21 (79.2%). In addition, our findings were similar to Razumova et al 18 (59.8%). A study reported the lowest incidence rate as 36.3%, when examined worldwide.…”

“…[7][8][9][10][11] Studies evaluating the root canal complex of teeth have used various techniques, such as canal staining and clearing, radiographic examination, and physical sectioning. [12][13][14][15][16][17][18] Although clearing and physical sectioning techniques are the best way to analyze root canal anatomy, they are invasive modalities indicated only for extracted teeth. According to position statements of the American Academy of Oral and Maxillofacial Radiology and the American Association of Endodontics, an intraoral radiograph is accepted as a standard pattern of the imaging modality of endodontic diagnosis.…”

Root canal morphology of mandibular premolars

“…A proper knowledge of root canal morphology is necessary for successful endodontic treatment (Alfawaz et al, 2019).The root canal system is complex and the canal may branch, divide and rejoin taking various pathways to the apex.Vertucci's established a proper method for differentiating root canal variations into the eight types.The classification has been widely used in several studies (Vertucci, Seelig and Gillis, 1974). As a group, the mandibular premolars are considered the most difficult teeth to treat endodontically and have high flare ups and high failure rates, as they have a high incidence of multiple roots or canals (Liu et al, 2013).Mandibular premolars may have extra root, not obvious in preoperative radiograph, challenging for shaping, cleaning, and obturation.Furthermore, the incidence, location, and morphology of root canal systems may vary in different ethnic or regional populations (Barakat et al, 2018;Alfawaz et al, 2019).…”
