Abstract
NOGUEIRA, Flávia Cracel et al. Root canal treatment of a maxillary second molar with four mesiobuccal root canals - a case report. Rev Port Estomatol Med Dent Cir Maxilofac [online]. 2022, vol.63, n.1, pp.35-40. Epub Mar 30, 2022. ISSN 1646-2890. https://doi.org/10.24873/j.rpemd.2022.03.862.
Among the roots of maxillary molars, the mesiobuccal often presents with a root canal system that may be complex and variable, leading to a greater challenge when trying to achieve a proper chemo-mechanical preparation. The present report intends to show a successful root canal treatment of a maxillary second molar with six root canals, of which four were present in the mesiobuccal root. After being diagnosed with pulp necrosis and symptomatic apical periodontitis, a molar was endodontically treated. It also had an uncommon paracone cusp. A careful inspection of the pulp chamber floor revealed a mesiopalatal sulcus, which, after exploration with ultrasonic tips under an operating microscope magnification, showed three additional mesiobuccal root canals. After proper mechanical debridement, disinfection with sodium hypochlorite, and warm gutta-percha obturation, a favorable outcome was observed at the 12-month follow-up.
