“…Thus, identifying the root canal anatomy of different ethnic populations is essential for successful endodontic treatment. 1,2 Many studies have examined root and canal morphologies using various methods such as sectioning, 3 canal staining, and tooth clearing techniques, 4 modified canal staining and clearing, 1 conventional radiography techniques, 5 contrast medium-enhanced radiography, 6 and computed tomography (CT) scanning. 7 Radiography provides information regarding tooth morphology such as pulp chamber size and degree of calcification, root structure, root curvature, location and number of canals, fractures, and iatrogenic defects.…”

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.

“…The presence of four root canal systems in maxillary molars has been well-documented, usually with two canals in the mesiobuccal root [2,18], but the presence of five root canal systems is quite rare [8]. A review of published case reports shows that the majority of palatal roots contain a single root canal system, but 1.2-3.4% of maxillary molars contain two palatal root canal systems [7,8].…”

“…Variations in canal configurations make root canal systems a challenge to locate and negotiate. Maxillary molars most commonly have 3 roots, but there is considerable variation and complexity in the root canal systems within those roots [2][3][4][5][6]. The majority of palatal roots in maxillary molars have single canals, but 1.2-3.4% of maxillary molars have two palatal canals [7,8].…”

Objective: Failure to identify and treat all canals within the root canal system is a major reason for endodontic failure. The morphological variations of the maxillary first molar have been the subject of many studies, with most studies focusing on multiple canals within the mesiobuccal root, but maxillary molars may also have fins, isthmi, lateral canals, and in this case, additional palatal canals. Identification and treatment of all canals and anatomical variations is vital for a successful endodontic outcome. Methods:A maxillary first molar with pulpal necrosis and asymptomatic apical periodontitis due to a deep carious lesion was accessed for root canal treatment under a dental operating microscope. Four canals were minimally instrumented to an apical size #20 and treated with the GentleWave ® Procedure. The GentleWave Procedure involves Multisonic Ultracleaning™ that creates cavitation with activated distilled water, sodium hypochlorite and ethylenediaminetetraacetic acid (EDTA). After the GentleWave Procedure, a fifth canal, not previously realized, was detected in the palatal root. The fifth canal had been visibly cleaned of debris. Five canals were obturated utilizing gutta-percha and warm vertical condensation with an epoxy resin based sealer.Results: Post-operative radiographs show 5 root canals: 2 palatal canals, 2 mesiobuccal canals, and 1 distobuccal canal. A cone-beam computed tomography (CBCT) scan shows a three-dimensional fill and obturation of complex anatomy. Three-month follow-up evaluation shows radiographic and clinical healing, resolution of periapical lesions, and complete resolution of the clinical symptoms. Conclusion:This case reports describes successful endodontic treatment of a rare maxillary molar with 5 canals, one of which was uninstrumented, utilizing an advanced technology, the GentleWave Procedure. This report highlights the importance of identifying and cleaning complex anatomy to increase successful outcomes.

“…In earlier studies, the pulp cavity was analyzed using intra-oral radiographs with files inserted into the cavity [120][121][122][123] as well as the cross sections of extracted teeth [124]. While these studies evaluated the two-dimensional (2D) structure of the pulp cavity, other studies evaluated the 3D configuration of the same using extracted tooth samples injected with Indian ink and made transparent using methyl salicylate [125][126][127].…”
