Lateral lymph node dissection (LLND) is getting global attention as an a surgical option to reduce local recurrence in locally advanced rectal cancer. As the transanal total mesorectal excision (TaTME) is gaining popularity worldwide, a novel LLND approach was established adopting a two-team approach that combines the transabdominal and transanal approaches using the TaTME technique. This narrative review describes the advantages, anatomical landmarks, surgical techniques, and pitfalls of transanal LLND (TaLLND).

Internal root resorption (IRR) is a rare but complex condition characterized by progressive destruction of the internal dentin walls, typically resulting from chronic pulp inflammation, trauma, or infection. Managing apical IRR, particularly in teeth with extensive apical lesions, presents significant challenges due to the limitations of traditional root canal treatment (RCT) and obturation techniques. This report discusses the nonsurgical management of two contralateral mandibular first molars in a 49-year-old male patient, both exhibiting apical IRR and large endodontic lesions.

BACKGROUND Internal root resorption (IRR) is a rare dental condition characterized by the progressive resorption of dentin within the root canal, often resulting from infection, trauma, or orthodontic treatment. When IRR progresses to perforation, it creates a communication pathway with periodontal tissues, necessitating effective endodontic therapy and perforation repair. Bioceramic sealers, known for their biocompatibility and flowability, have emerged as a promising alternative to traditional materials for filling and sealing the root canal system.

Background: Local relapse has not been eradicated even in the era of total mesorectum excision. Although various approaches have been attempted, R0 resection remains the only potentially curative treatment. PATIENT AND METHODS: A 45-year-old woman with a history of laparoscopic abdominoperineal resection was diagnosed with pelvic recurrence 7 months ago.

Apexification is a crucial procedure for achieving apical healing in non-vital teeth with open apices. Traditionally, calcium hydroxide has been used for this purpose, but it has significant drawbacks, including prolonged treatment duration, increased risk of root fracture, and the potential for porous barrier formation. Mineral trioxide aggregate (MTA) has emerged as a superior alternative due to its biocompatibility, faster setting time, and better sealing properties.
