| Outline of Final Research Achievements |
Recently, patients with atypical tooth pain, glossodynia and tempolomandibular disorder have been increasing and this phenomenon was recognized as social issues. This study was designed to determine whether sialorphin that displays analgesic activity can be effective for pain control in the maxillofacial regions both of the acute-pain model rats induced by formalin injection and of the chronic-pain ones induced by trigeminal (maxillary) nerve constriction. In conclusion, sialorphin had inhibitory effect both on the formalin-induced acute pain and on the chronic pain induced by nerve constriction.
