Root canal morphology analysis of maxillary permanent first and second molars in a southeastern Turkish population using cone-beam computed tomography

Abstract

Background/purpose: The aim of this retrospective study was to determine the root and canal morphology of the maxillary first and second molars in a Turkish subpopulation using cone-beam computed tomography (CBCT). Materials and methods: CBCT images of 417 women and 410 men aged 14e70 years were examined. A total of 1158 maxillary permanent first molars and 1305 maxillary permanent second molars were analyzed. The number of root canals and canal configurations were investigated and classified according to Vertucci's classification. The data were analyzed using Pearson's Chi-square test. Results: In both first and second maxillary molars, the presence of three roots was the most common occurrence. The prevalence of additional canals (type II, III, or greater) in mesiobuccal roots of maxillary first and second molars was approximately 62% and 37.5%, respectively. Type I canal configuration was the most prevalent in the distobuccal (99.6%) and palatal (99.8%) roots of maxillary first molars, and in the distobuccal (99.7%) and palatal (99.2%) roots of maxillary second molars. The incidence of the number of root canals and the configurations of maxillary first and second molars did not statistically differ with sex (P > 0.05). (M.

Conclusion:The high prevalence of additional canals in the mesiobuccal roots of maxillary first and second molars is noteworthy. CBCT is an effective method to study the external and internal morphology of dental tissues.

Root and root canal morphology of the permanent dentition in a Caucasian population: a cone‐beam computed tomography study

“…The mesiobuccal root of the maxillary first molar with three independent roots was more prone to exhibit two root canals (71.05%). These data are in line with the results obtained in Turkey (Altunsoy et al 2015), India (Felsypremila et al 2015), the United States (Guo et al 2014) and in Asiatic countries such as Korea (Kim et al 2012) and China (Zhang et al 2011b, Tian et al 2016. Other studies from Brazil (Silva et al 2014), Italy (Plotino et al 2013) and India (Neelakantan et al 2010) reported prevalences of a single root canal (Vertucci Type I) in 52.87%, 59.7% and 51.8% of cases, respectively.…”

Root Anatomy and Root Canal Morphology of Maxillary Second Permanent Molars in a Chongqing Population: A Cone-Beam Computed Tomography Study

“…Root canals that have not been completely treated or are missed are the main causes of failure of endodontic therapy [ 5 , 6 ]. The configuration of root canals in human teeth is quite complicated and varies among different populations and races [ 3 , 7 , 8 ]. However, the complexity of the internal anatomical structure is usually masked by the relatively simple external anatomy [ 9 ].…”

Frecuencia del cuarto conducto y variaciones anatómicas en segundas y terceras molares superiores mediante tomografía computarizada de haz cónico

“…Altunsoy et al(17) determinaron la raíz y la morfología del conducto de los primeros molares y segundos maxilares en una subpoblación de Turquía con el uso de tomografía de haz cónico computarizada (CBCT). Tanto en las primeras y segundas molares superiores, la presencia de tres raíces fue la ocurrencia más común.…”
