[The effect of metal ceramic crowns on the enzymatic activity of the gingival fluid].
Analysis of the enzymic activities of the gingival fluid obtained round the teeth supplied with metal ceramic crowns with the edges situated on different levels as against the gingival sulcus has revealed an elevation of lactate dehydrogenase, acid and alkaline phosphatases, glutamyl transpeptidase and cholinesterase activities in the gingival fluid from sites where the metal ceramic crown edges were hidden under the gingiva. When the crown edges were on the edge of the gingiva the enzymic activities were found unchanged. The mechanisms of the detected shifts are discussed.
