Serial Clinical Observation of Soft Tissue Response to a Sodium Hypochlorite Accident: A Case Report
Sodium hypochlorite (NaOCl) is widely utilized as an endodontic irrigant due to its antimicrobial efficacy and tissue-dissolving capabilities. Its mechanisms of action involve hypochlorous acid, chloramines, and the solution’s high alkalinity, which contribute to tissue dissolution through protein degradation and saponification of lipids. While effective for disinfecting root canals, unintended extrusion beyond the apical foramen can cause severe chemical injury. Although cases of NaOCl accidents have been reported, detailed serial clinical documentation of tissue responses following such incidents remains limited in the literature. This case report presents a 66-year-old female who developed acute pain during root canal irrigation of the mandibular left lateral incisor (#32) due to NaOCl extrusion. Initial findings included a mucosal opening suggestive of subepithelial necrosis, followed by bilateral chin ecchymosis and intraoral tissue degradation. Over the following days, signs of liquefactive and fat necrosis emerged, eventually progressing to tissue remodeling with re-epithelialization and fibrotic healing. Cone-beam computed tomography revealed a periapical lesion with buccal bone fenestration, indicating a possible anatomical route for extrusion. The root canal was obturated once soft tissue healing was evident, and by 12 weeks, the affected area had fully recovered with scar-like integration into surrounding mucosa. This case report highlights the importance of identifying anatomical risk factors such as buccal bone fenestration to prevent extrusion and underscores the value of timely, conservative management. Close follow-up is important for monitoring soft tissue changes and guiding appropriate intervention.

Sialadenoma papilliferum is a rare benign salivary gland tumor, accounting for approximately 0.4–1.2% of all salivary gland neoplasms. It most commonly occurs in the hard palate, followed by the soft palate, buccal mucosa, upper lip, and, rarely, the esophagus. The condition is typically asymptomatic and is often discovered incidentally during routine oral examinations. We report the case of a 56-year-old man who presented with pain in the left hard palate and was referred to Kyungpook National University Dental Hospital. Enhanced CT revealed a 1.5-cm ovoid lesion in the left paramedian hard palate. Biopsy confirmed the diagnosis of sialadenoma papilliferum, and based on the radiological findings, surgical excision was performed under general anesthesia. The microscopic histopathological examination of the specimen (size: 1.0 x 0.7 cm) revealed papillary proliferation of stratified squamous epithelium with hyperkeratosis and underlying ductal structures lined by mucin-producing cells with mucinous material in the cystic spaces.
