We usually use Vitapex® as a root canal filling. This report describes a case of inferior alveolar nerve hypoesthesia caused by overfilling a root canal with Vitapex®.Case: A 23-year-old woman was referred to our hospital because of hypoesthesia of the inferior alveolar nerve.She had undergone treatment of 7 with root canal filling using Vitapex® one week earlier at another clinic. On the following day, she had hypoesthesia of the skin of the right side of the chin. X-ray examination showed a radiopacity in the right mandibular canal.After 4 months of conservative management, hypoesthesia decreased.Soon after, we extracted 7.Her subsequent course has been uneventful, and only a small hypoesthestic area remains.

Amyotrophic lateral sclerosis (ALS) is a progressive neuromuscular disease that affects both upper motor neurons and lower motor neurons.Here is a case of ALS with predominantly bulbar involvement. The patient is a 63-year-old male. He was referred to the Department of Oral Surgery, Kurume University School of Medicine with chief complaints of inability to speak clearly and difficulty in eating. On oral examination, atrophy and muscular fasciculation in the tongue were found. There was no loss of aberrations in taste. Except for dysphagia and masticatory disturbance. he had no difficulty practicing his profession. Subseqently, he was diagnosed by the neurologist as having progressive bulbar palsy (PBP) in a motor neuron disease.When the onset of ALS is predominantly bulbar in origin, the patient may first consult a dentist because of the oralfacial symptoms of dysphagia, dysarthria, masticatory disturbance, and muscular weakness. It is important for the dentist to recognize a motor disability and to control the condition without neglecting the nature and severity of the disease.

To assess the malignant potential of tongue cancer by intraoral ultrasonography, we examined 22 patients with squamous cell carcinoma of the tongue. Ultrasongraphic findings of the lesions were evaluated with respect to shape, border, internal echo, marginal echo, and depth of invasion (usD). Except for 3 tumors with a pathologic depth of invasion (pD) of less than 1 mm, 19 of 22 tumors (86.4%) were detected as hypoechoic lesions on intraoral ultrasonography. When the ultrasonographic and clinicopathologic findings were compared, tumors with diffuse invasion exhibited irregular shapes and diffuse borders on ultrasonography. Tumors with neck metastasis showed irregular shapes, diffuse borders, and hyperechoic marginal echoes. In addition, there was a significant correlation between usD and pD. Seven (58.3%) of 12 tumors with invasion of 8.0mm or more on ultrasonography were associated with neck metastasis.<BR>In conclusion, intraoral ultrasonographic examination of tongue cancer provides information useful in evaluating tumor extent and malignant potential.
