ジャーナル 認証ありThis study aimed to investigate factors affecting the warm, cold and tactile thresholds of the oral mucosa. Thirty subjects aged 24-37 years participated in the study. Measurement points were the tip and dorsum of the tongue, and the anterior of the buccal mucosa. Surface temperature and sensory threshold were measured for these points before and after applying thermal stimuli of 60°C and 4°C for 1 min each (15 s × 4). Threshold recovery times were measured after the application of each stimulus. The relationship between these changes and their causative factors were examined.
The tip of the tongue in the absence of stimulation had the lowest values for surface temperature and sensory threshold. Warm and cold thresholds changed significantly after application of warm and cold stimulation. Warm thresholds increased while cold thresholds decreased after warm stimulation. Conversely, cold thresholds increased while warm thresholds decreased after cold stimulation. On the other hand, tactile thresholds changed significantly only on the tip of the tongue and buccal mucosa after cold stimulation. Tactile thresholds were the fastest to recover among the three thresholds. Gender, flavor preference (e.g. rich, sour, piquant) and drinking habit were determined as factors affecting surface temperature, sensory threshold and recovery time.
Sensory thresholds changed with experience of daily stimuli. In addition, the longest recovery time was 16 min; therefore, for correct results and diagnosis, it may be necessary to remove stimuli for at least 16 min before sensory examination.抄録全体を表示PDF形式でダウンロード (642K)

ジャーナル 認証ありSquamous cell carcinoma of the jaw located purely in the bone is rare. Some of these primary intraosseous squamous cell carcinomas are thought to arise from the epithelial lining of an odontogenic cyst. We report a case of primary intraosseous squamous cell carcinoma of the mandible arising from a dentigerous cyst. A 36-year-old woman was referred to our department by her dentist because of a swelling and pain in the mandibular left retromolar region. Radiographic examination showed a unilocular radiolucency with well-defined borders surrounding the impacted third molar in the left-side mandible. Under a clinical diagnosis of dentigerous cyst involving the left mandibular third molar, enucleation of the cyst and extraction of the impacted tooth were performed. Histopathological examination of the surgical specimens showed a cyst with a non-keratinizing epithelium lining and squamous cell carcinoma. One month after the first operation, segmental resection of the mandible with supraomohyoid neck dissection was performed. The defect after mandibulectomy was immediately reconstructed with a scapula osteocutaneous flap. The patient has been followed up for 3 years and 7 months, with no evidence of recurrence or metastasis.抄録全体を表示PDF形式でダウンロード (855K) -

ジャーナル 認証ありWe present three cases of tumors that showed a variety of pain symptoms in the orofacial region. One patient complained of TMJ pain on the right side and was finally found to have a brain tumor in the cerebellopontine angle. The second had been diagnosed as having myofacial pain and had been prescribed a muscle relaxant and minor tranquilizer in a neurosurgery hospital but was finally found to have a malignant lymphoma in the base of the skull. The third had undergone a course of hormone therapy for prostate cancer one year earlier, and presented with facial pain in the upper left gingiva, which was finally found to be related to metastatic brain tumor. In conclusion, we should consider cerebral and skull base tumors as a cause of orofacial pain in clinical practice.抄録全体を表示PDF形式でダウンロード (1041K)
