Influence of Prosthetic Crowns on Gingival Fluid

Purpose: Evaluation of the impact that a foreign body has in the gingival sulcus, expressed in scale to cause significant gingival infection. Material and Methods: In a sample of 10 clinical cases with fixed prosthetic appliances in the oral cavity, the levels of gingival fluid to bridge anchoring teeth are measured and compared to the same opposite respective teeth in the mandible and in the maxilla. Measurement of gingival fluid was done with the blue coloured absorbent paper, kept in the gingival sulcus for 60 seconds. With the technique of centrifugation the respective values of gingival fluid were found. Result: Levels of gingival fluid were distinguishably different around the anchor teeth of bridges compared to natural teeth. Conclusions: Signs of primary infection onset are manifested by an increased gingival fluid. The presence of a foreign body caused an increase of gingival fluid in the sulcus, as a sign of physical harassment, possibly causing an initial stage of gingival inflammation.
