Abstract

Background: This study aimed to investigate the changes of the amount of P. gingivalis in saliva by professional preventive treatment of periodontal disease by dental hygienists. Methods: A total of 109 subjects participated in this study with informed consent. The control group (38 subjects) performed oral hygiene management individually. The periodontal treatment group (35 subjects) underwent root planning once every 3 weeks for a total of 4 times. The professional periodontal prevention group (36 subjects) underwent interdental cleaning and professional tooth brushing once every 3 weeks for a total of 4 times. Paired T test and analysis of variance were performed to compare the difference among the groups in the amount of P. gingivalis. Results: The copies of P. gingivalis in the professional periodontal prevention group decreased from 773.62±1,198.09 to 241.40±430.40 after treatment significantly. The control group decreased from 525.22±582.54 to 244.29±385.88 after treatment. The periodontal treatment group showed insignificant change of P. gingivalis. Conclusions: This study showed the professional periodontal prevention was more effective than periodontal treatment in decrease of P. gingivalis.
