Myospherulosis in the periapical region following root canal treatment

Abstract

This report explores a unique manifestation of myospherulosis in the periapical region of lower anterior teeth following root canal treatment with calcium hydroxide Ca(OH)2. A 38-year-old woman complained of enduring pain in her lower front teeth for the past 15 days. During the clinical examination, it was observed that the labial vestibule in the lower anterior region was obliterated. The teeth exhibited tenderness upon percussion. Radiographic examination indicated an ill-defined radiolucency in the periapical region, prompting further investigation into the delayed healing. Histopathological examination of the periapical tissue unveiled cyst-like spaces containing brownish-black-stained spherules, indicative of myospherulosis. Curettage with apicectomy was performed to address the delayed healing. A 6-month follow-up revealed complete healing of the lesion, emphasizing the successful management of myospherulosis-induced delayed healing. The unintended consequence of myospherulosis development emphasizes the importance of preventing medicament overflow into the periapical region during root canal therapy to minimize the delayed healing process.
