An evaluation of the quality of the fabrication of removable plate dentures by the histamine content in mixed saliva

: Clinical and laboratory study, aimed at development of an objective criterion that would permit assessment of the quality of plate dentures early after orthodontic treatment, was carried out in 66 subjects aged 45 to 74 years. The examinations carried out before and after orthodontic treatment revealed a relationship between histamine concentrations in the background salivary pool and the presence of inflammation signs in denture bed tissues in the first days after plate denture application. The detected relationship may be regarded as an additional objective criterion permitting assessment of the denture quality in early periods after orthodontic treatment.
