Abstract:
Objective:To observe the changes of plaque microflora during the experimental gingivitis and to analyze the relationship between the plaque microflora and the clinical parameters.Methods:11 young male subjects with healthy gingiva and without systemic disease were selected.Subgingival plaque samples(2 sites /person)were collected and then smeared by Gongo red at baseline(0 day),the 7th,14th,21st day(without oral hygiene)and 28th day(7 days after reestablishing oral hygiene)respectively during experimental gingivitis.At the same time the clinical parameters were recorded.The results of smear and the clinical parameters were analyzed.Results:The percentage of spirochete was the lowest at the baseline and increased during the experimental gingivitis,and then reached the highest level on the 21st day.The percentage of spirochete of the 21st day showed the significant different compared with that of baseline(P0.05)Conclusion:Spirochete is correlated to the development of the gingivitis.
