Összefoglaló szövege

Introduction: The anatomical structure of the tissues surrounding dental implants differ from the tissues surrounding natural teeth. This could be the reason that blood flow in peri-implant mucosa is reduced. However, it is not known whether this reduced resting blood flow could influence vasodilation capacity of the gingiva. In our previous studies we found that very short occlusion of gingival vessels resulted in long term hyperemia spread to the neighboring teeth.
Aim: The aim of the present study is to compare the post-occlusive reactive hyperemia between teeth and implants.
Materials and methods: Fourteen medically healthy volunteers with solo dental implants were involved in our study. After 1 minute lasting baseline measurement pressure was applied on the attached gingiva with a special angulated manual instrument for five seconds. After occlusion the blood flow was monitored continuously for 20 minutes (follow-up). Measurements were made on the attached gingiva surrounding the solo crowns of the dental implants and surrounding the analogue natural teeth. Measurements were made with the laser speckle contrast imager. Data were analyzed by Linear Mixed Model using case as subject and the baseline blood flow and age as covariates.
Results: No significant differences were observed in baseline GBF between implant and tooth in either regions (apical: 244±19 vs 268±17, central: 237±15 vs 269±16, coronal: 229±13 vs 260±14 LSPU). The occlusion induced ischemia and followed by hyperemia in all regions. The magnitude of change in GBF due to the occlusion was similar in central and coronal regions. In apical region the hyperemia was significantly higher at the tooth than at the implant after 5 min (62±21 vs 90±17 dLSPU, p<0.05).
Conclusions: Our study failed to demonstrate differences in resting gingival blood flow between implants and teeth contrary to previous studies. However the vascular reactivity may be reduced in peri-implant gingiva.
