Abstract:
Objective:To study the effects of biologically oriented preparation technique(BOPT)on periodontal plaque colonization and inflammatory factor expression in gingival crevicular fluid(GCF).Methods:102 patients with chronic periodontitis were randomly divided into 2 groups(n=51).The subjects in control group received traditional tooth preparation,while those in observation group re-ceived BOPT.The probing depth,modified plaque index,gum papillary index,marginal bone resorption and modified gingival groove bleeding index were measured and compared between the 2 groups.The GCF was collected at the restoration site before and after 6 month restoration,the levels of tumor necrosis factor-α,interleukin-6 and matrix metalloproteinase 8 were measured at different time periods.Results:6 months after surgery,there was no significant difference in near-middle,far-middle and mean bone resorption be-tween the 2 groups(P＞0.05).The restoration periodental indexes were decreased in both groups(P＜0.05),and the modified gingival hemorrhage index,probing depth,gum papilla index and modified plaque index in the observation group were obvious lower than in the control(P＜0.05).The inflammatory factor expression in GCF was significantly decreased in both groups(P＜0.05),and in the obser-vation group was obvious lower than in the control(P＜0.05).Patient comfort,retention function,aesthetics and total score in the ob-servation group was obvious higher than in the control(P＜0.05),but there was no statistically significant difference in chewing func-tion,language function between the 2 groups(P＞0.05).Conclusion:BOPT may improve the restoration level,eliminate the inflamma-tory response of GCF and improve satisfaction in patients with chronic periodontitis.
