口腔正畸治疗中RGp检出率变化及对牙龈炎发生的影响
Detection Rate Change of RGp in Orthodontic Treatment and Its Effects on Gingivitis
摘要
Abstract
ObjectiveTo investigate changes in the detection rate of gingipain R (RGp) in orthodontic treatment and its effects on gingivitis.Method72 patients undergoing orthodontic treatment were selected.The patients' gingival crevicular fluid samples were taken on 60 days before and after the application of the appliance as the research samples,16S rDNA PCR was applied to test Porphyromonas gingivalis (P.g) in the samples,and P.g-positive samples were used for the further detection of RGp;at the same time,the gingival indexes were detected with a periodontal probe,and the correlation of gingival index with the change in the detection rate of P.g and RGp was analyzed.ResultsOn 60 days after the application of the appliance,the detection rates of P.g and RGp were significantly higher than those before it,with a statistically significant difference (P<0.05);RGp and P.g showed a positive correlation in the detection rate.P.g detection rate of gingival index (Grade I) on 60 days after the application of the appliance was significantly higher than that before putting into the gingival index (Grade 0),showing a statistically significant difference (P<0.01);The P.g detection rate of gingival index (Grade I) after the application of the appliance was significantly higher than that before putting into the gingival index (Grade 0),showing a statistically significant difference (P<0.05).In P.g-positive patients,the RGp detection rate of gingival index (Grade I) on day 60 after the application of the appliance was significantly higher than that (Grade 0) before it (P<0.01);the RGp detection rate of gingival index (Grade I) after the application of the appliance was significantly higher than that (Grade 0) before it (P<0.05).The detection rate of P.g and RGp was positively correlated with the grading of the gingival index.ConclusionThe P.g infection and the level of RGp can cause gingivitis in the orthodontic treatment,and some interventions should be given to the patients after the application of the appliance.关键词
