ABSTRACT
Objective:
To study the feasibility of the early diagnosis of chronic periodontitis using near-infrared diffuse correlation spectroscopy(DCS).Methods:
30 subjects were inclded.The relative gingival blood flow(GBF) at the labial,mesial and distal healthy gingiva(the control) or the gingiva with periodontitis of maxillary anterior teeth was respectively measured by DCS before periodontal treatment,a week and a month after treatment.Results:
The GBF of healthy gingiva group,gingivitis group and periodontitis group was 129.73 ± 10.70,95.51 ± 11.83 and 67.84 ± 13.05 respectively.Periodontal indexes were decreased and the relative GBF increased significantly 1 week and 1 month after treatment.Gingival index and sulcus bleeding index were respectively correlated to relative GBF(r =-0.902,r =-0.893).Conclusion:
Near-infrared diffuse correlation spectroscopy can non-invasively detect the relative gingival blood flow in different stages of chronic periodontitis,it may be a method of early diagnosis of chronic periodontitis.
