Effect Of Risk PRA Assessment On The Short-term Prognosis Of Middle-aged And Elderly Patients With Chronic Periodontitis

Objective:The study of middle-aged / elderly group of chronic periodontitis(chronic periodontitis CP)in patients with gingival curettage,comparative scaling before and after periodontal probing depth(probing depth,PD)and the attachment loss(attachment loss(AL)changes,in order to explore middle age group and elderly group in PRA risk assessment grade periodontitis therapy clinical prognosis.Method:In Nanchang University Second Affiliated Hospital Department of oral treatment of 40 cases of chronic periodontitis patients were divided into 20 cases of middle-aged group(35 to 64 years old),elderly group(65 to 74 years old)have 20 cases,23 cases of male,female 17 cases.According to the pra(periodontal risk assessment risk assessment system patients were divided into three levels: low risk,low risk,LR)and risk(moderate risk,MR)and high risk high risk(HR).Before the subgingival scaling and after the subgingival scaling(3 months)resptwo ectively,with Florida electronic pressure sensitive probe system(hereinafter referred to as the Florida probe)measurement of the remaining teeth(except the third molars)the mesiobuccal(MB),buccal(B),and distobuccal(DB),mesiolingual(ML),Lingual(L)of distolingual(DL)six sites of PD and AL,incorporated into the remaining teeth a total of 1045,before and after periodontal basic treatment each 6270 sites.Changes of scrape before and after the treatment of PD and AL(1)compared each teeth under the gums;(2)compared to the same level of risk middle-aged / elderly group before and after subgingival curettage for PD and AL difference;(3)compared with age group in the different levels of risk subgingival curettage before and after PD and AL difference.Result:1?After subgingival scaling,PD and AL were both decreased in middle-aged group andelderly group in LR,MR and HR before and after scaling,and the difference was statistically significant(P<0.01).2? LR in middle-aged PD and AL were higher than the elderly group,the difference was statistically significant(P<0.01);MR and HR were compared between the middle-aged and elderly groups PD and AL difference was not statistically significant(P>0.05).3? The middle-aged group LR subgingival curettage before and after PD and AL difference were higher than that of HR,the difference is statistically significant(P < 0.01)LR and MR,Mr and HR subgingival curettage before and after PD and AL difference had no statistical significance(P > 0.05);in the elderly group LR and HR subgingival curettage before and after PD and Al difference has statistical significance(P < 0.01).The PD and AL difference LR higher than HR.LR and MR,Mr and HR subgingival curettage and PD and AL difference comparison were no statistical significance(P > 0.05)Conclusion:1? After subgingiva scaling,The PD and AL were significantly lower after treatment than before treatment,which indicated that the clinical effect of periodontal basic treatment was obvious.2? LR middle-aged group than in the elderly group,PD and AL difference increased significantly,indicating that the lower middle-aged group LR clinical effect is better.3? The difference between HR and LR in middle-aged group and elderly group was significantly higher than that of PD,while LR and MR,HR and MR,PD and AL were not significantly changed,the lower the risk grade,the clinical effect was better after periodontal treatment.
