RESUMEN
The aim of this study was to find out if juxta-apical radiolucency (JAR) is a reliable risk factor for injury to the inferior alveolar nerve (IAN) during removal of lower third molars. We designed a cohort study of patients whose dental panoramic tomograms (DPT) had shown JAR before complete removal of lower wisdom teeth. The outcome variable was postoperative permanent neurosensory disturbance of the IAN. A total of 39 patients (50 lower third molars) were identified and screened for permanent neurosensory disturbance. None reported any permanently altered sensation 18 months after the operation. Based on our group, the presence of JAR does not seem to be a reliable predictor of the risk of permanent injury to the IAN during removal of lower third molars.

A 34-year-old man experienced extensive oral ulceration as a consequence of attempted ingestion of sulphuric acid as part of an act of deliberate self harm. All oral lesions healed within 28 days after local and systemic therapy. Oral ulceration has many potential causes ranging from physical trauma to malignancy. Chemicals are a less common cause of traumatic ulceration. Most chemical burns are characterised by mild to moderate tissue damage that heals spontaneously within seven to 15 days without scarring.
