For pain research, the orofacial region is unique in a number of ways. The region has complex local anatomy, including substantial sensory innervation from neural pathways, and muscles of facial expression that convey important information concerning pain intensity and associated psychological traits. Although chronic orofacial pain conditions appear prevalent, useful documentation on pain intensity ratings using well established instruments is sparse. In particular, two conditions, atypical facial pain and atypical odontalgia, are poorly understood in aetiology so that definitive treatment modalities are severely limited. The region's local biofluid, saliva, has been used to diagnose various local and systemic disease states, and to quantitate drug concentrations. However, recent studies indicate that saliva also contains some of the same peptides, e.g. bradykinin, that are involved in pain mechanisms. It may be that pharmacological-pharmacokinetic studies of these peptides could shed more information on thesignificance of their presence in saliva. This thesis consists of four major sections. Section 1 comprises of three clinical studies investigating orofacial pain. Section 2 deals with clinical laboratory studies of saliva. Section 3 is concerned with the development of chromatographic methods to assay bradykinin and its pharmacokinetics in saliva. Section 4 uses chromatography for the identification of novel salivary peptides. This thesis, then, presents clinical studies of orofacial pain and pharmacological investigations of saliva as the local biofluid.
