Anatomical Variations in Mandibular Molars: Focus on Midmesial Canals.

Endodontic therapy focuses on the root canal system to treat infected or damaged pulp tissue within the tooth, ultimately preserving the tooth and restoring its function. The root canal space should be cleaned with the use of proper instruments and chemical disinfectants to eradicate infected pulpal tissue and its remnants. The failure of endodontic therapy is attributed to a lack of understanding of the differences in anatomy among teeth, as evidenced by research. Canals are identified, and endodontic treatment is facilitated by the use of dental operating microscopes. Therefore, to achieve a favorable endodontic result, it is imperative to use all available methods to identify additional aberrant root canals. Failure to detect and adequately treat the midmesial canal (MMC) can lead to persistent infection, treatment failure, and the need for retreatment. This case underscores the importance of meticulous assessment and advanced techniques in treating complex canal configurations, ultimately leading to favorable outcomes in endodontic therapy. The MMC, a challenging anatomical feature, was located through careful clinical and radiographic examination. Advanced techniques, including ultrasonic activation and meticulous instrumentation, were employed to navigate and clean the canal effectively. Sodium hypochlorite irrigation and passive ultrasonic activation were utilized for thorough disinfection. The MMC was sealed with biocompatible materials, ensuring comprehensive obturation of the root canal system.

Diving Deep: Exploring Dual Palatal Canals in the Upper Second Molar.

Dental anatomy exhibits considerable variation with the presence of additional canals being a common occurrence. The upper second molar typically presents with three canals and three roots; however, variations such as the existence of an extra canal or a root can pose challenges during endodontic treatment. Maxillary molar is characterized by an additional canal located within the palatal root, often exhibiting complex configurations and variations in morphology. Access refinement is critical to gaining adequate visibility and facilitating instrumentation. Meticulous exploration of the pulp chamber floor and careful examination of radiographs from different angles are essential for accurate diagnosis. Careful negotiation and cleaning of the extra canal with appropriate files and irrigants are essential to remove pulp tissue and debris effectively. Furthermore, obturation of the canal space with biocompatible materials is crucial to ensure a three-dimensional seal and prevent bacterial ingress. Clinically, the inability to detect and treat the extra palatal canal can lead to persistent infection, incomplete debridement, and compromised treatment outcomes. This case report delves into the significance of this anatomical variation, diagnostic modalities, and effective management strategies.

Morphometric Analysis of Radix Entomolaris: Implications for Endodontic Access and Treatment.

Radix entomolaris (RE) is an anatomical variation that involves the existence of an extra root in lower molars, particularly the first molar. This variant, although less common, has significant clinical implications in endodontic treatment and dental surgeries. Appropriate detection of radix entomolaris is crucial for treatment planning and prognosis. Various diagnostic aids like radiography, cone-beam computed tomography, and intraoperative exploration aid in identifying this anatomical variant.

Evolution of Biomimetic Approaches for Regenerative and Restorative Dentistry.

Biomimetics refers to human-made processes, substances, systems, or devices that imitate nature. The art and science of designing and building biomimetic apparatus are called biomimetics. This method can be widely used in dentistry to restore the structure and function of normal tooth structure. Traditional approaches to treating damaged and decayed teeth require more aggressive preparation to place a "strong," stiff restoration. The emphasis was made on the strength of the restoration as well as its function and mechanical properties, despite several disadvantages like tooth fracture, making future treatment more difficult and invasive. This review paper will seek to provide a clear explanation of its scope, different fields of biomimetic dentistry, and materials used in biomimetics that improve the strength of the tooth.

The Comparative Evaluation of Postoperative Pain After the Use of WaveOne Gold and TruNatomy Filing Systems in a Tooth With Irreversible Pulpitis: An Observational Study.

Introduction The present study aimed to clinically compare the incidence of postoperative pain after the endodontic treatment of posterior teeth using the WaveOne Gold (WOG) and TruNatomy (Dentsply Maillefer, Ballaigues, Switzerland) filing systems. The study gives a better understanding of the association of postoperative pain and filing systems used. The patients were selected in such a manner that they have a similar diagnosis before the initiation of treatment. It also helps to understand if the postoperative pain is dependent or independent of the filing system used. Methods In the study, 32 vital teeth with irreversible pulpitis with no periapical lesion were selected for the study. The patients were divided into two groups (n=16) according to the instrumentation system used (WaveOne Gold group and TruNatomy group). The treatments were performed in a single session. The participants were asked to rate the intensity of postoperative pain on a visual analog scale (VAS) (no pain, mild pain, moderate pain, and severe pain) after 24 hours, 72 hours, and seven days; the tests of significance used are Friedman test or Mann-Whitney test. Results The incidence of postoperative pain is comparatively less in WaveOne Gold group after 24 and 72 hours compared with those in the TruNatomy group. No postoperative pain is experienced after seven days by the participants of both groups. Conclusions Postoperative pain is expected more after the preparation of the root canal system with the TruNatomy as compared to WaveOne Gold.
