A Limited and Useful Approach to Determine Proximal Periodontal Health



Previous researchers have shown that there exists an interaction between gingival blood flow and gingival health. The purpose of this study was to compare the papillary blood flow at sites treated by a bridge with the blood flow at untreated sites. Twenty persons with resin-bonded fixed partial dentures were included in the study. The contralateral natural teeth of the site symmetrical to that of the restorations were used as controls. Blood flow was measured from the middle point of the papillae from both test and control sites by Laser Doppler Flowmetry (LDF). The plaque index, papillary bleeding index and probing depth measurements were recorded. There was a statistically significant difference between the test and control sites in papillary blood flow measurements and clinical indices (p < 0.05). Moreover, there was statistical significance between gingival blood flow measurements and papillary bleeding index in the experimental group (p < 0.05).
In short, there exists an important relationship between resin-bonded fixed partial dentures and papillary blood flow. Although there were no correlations between LDF values and clinical parameters, it can be emphasized, within the limits of the study, that LDF readings have limited diagnostic value, at least when it comes to clinical performance of fixed prosthesis.
