“…Необходимо отметить, что наличие срединного мезиального канала в мезиальном корне нижних моляров -распространенный вариант морфологии сложной корневой системы зуба. Однако сложность его детерминирования на этапе диагностики состоит в том, что на этапе рентгенодиагностики срединный канал не визуализируется ввиду малого размера, а на этапе ревизии полости зуба необходимо достаточное увеличение, что осуществимо при работе на операционном дентальном микроскопе [18][19][20][21].…”

Background. Inflammatory process in periapical tissues causes tooth extraction in more than 50% of cases. The development of chronic apical periodontitis can be triggered by an intracanal infection in undetected/missed root canal of the mandibular molars. The morphology of mandibular molars is distinguished by additional canals in the mesial root in some cases. Different studies reveal the middle mesial canal in 4.5% to 26% of cases with quite high incidence in youth. The dental therapy has been searching for effective approaches to diagnosis and treatment of chronic periodontitis, enabling the focus of chronic inflammation to be eliminated and the tooth to be saved. Case descriptions. The paper presents clinical cases of patients with destructive changes in bone tissues in the periapical region of the mesial root in mandibular molars. The developing of this pathology is associated with missed anatomy in the mesial root during primary endodontic treatment. The patients underwent clinical examination consisting of basic methods (interview, examination) and additional techniques (intraoral radiography). An additional middle mesial canal in the root of the mandibular molar was identified taking into account the complex morphology of the root system of the tooth and verified by its careful analysis and radiography. The final clinical diagnosis, chronic apical periodontitis (K04.5), was made following the obtained diagnostic results and the ICD-10 classification. Diagnostic examination and endodontic retreatment were performed using a dental operating microscope. Conclusion. An operating dental microscope provides visualization of microscopic anatomotopographical details, promoting the efficiency of diagnosis and treatment of chronic apical periodontitis in mandibular molars. Using dental microscope facilitates systematization of the data obtained during the examination, making a final clinical diagnosis, and development of a reasonable personalized treatment plan focused on detecting an additional middle canal in the mesio-buccal canal of the mandibular molar. Due to the suggested approach, the long-term outcomes of endodontic treatment can be an objective assessed in dynamics, thereby improving the quality of treatment for chronic apical periodontitis in patients.

“…C-shaped canals are most commonly found in mandibular second molars, followed by mandibular first premolars and molars, and maxillary first and second molars, with a higher prevalence in Asian populations [ 4 ]. Mandibular molars, frequently affected by decay, often require endodontic treatment, making them one of the most common teeth treated endodontically [ 5 ]. However, mandibular molars have a high extraction rate, mainly due to failed endodontic treatment [ 6 ].…”

Background Understanding root canal anatomy variations, particularly C-shaped canals, is crucial for successful endodontic treatment. This study used clinical and radiographic methods to assess the prevalence and characteristics of C-shaped canals in mandibular second molars in Western Maharashtra. Materials and methods This prospective study was conducted in the western region of Maharashtra, India. The samples included patients requiring endodontic treatment for mandibular second molars. Clinical evaluation was conducted using a surgical endodontic microscope and cone beam computed tomography (CBCT) imaging. Inclusion and exclusion criteria ensured the selection of a focused and homogeneous sample. Data analysis included assessment of unilateral/bilateral occurrence, canal distribution, and cross-sectional characteristics. Results Out of 200 mandibular second molars, 7.5% exhibited C-shaped root canals, with no significant gender differences. Canal distribution varied across coronal, middle, and apical levels, with prevalent configurations being C1, C2, C3, and C4. No significant differences were observed in canal distribution based on root levels. No significant gender differences were found in the presence of grooves on the root surfaces. Conclusion This study provides valuable insights into the prevalence and characteristics of C-shaped canals in mandibular second molars in Western Maharashtra. Further research into histological and genetic aspects can enhance our understanding, leading to improved treatment strategies for complex root canal anatomy variations.
