Abstract：Objective:To analyze the curative effect of periodontal tissue regeneration combined with Cervitec gel on periodontitis.Methods:A total of 180 patients with periodontitis treated in our hospital from January 2017 to January 2019 were enrolled in this study and randomized the observation group and control group,with 90 in each.The patients in the control group were treated with periodontal tissue regeneration,and those in the observation group with Cervitec gel.Periodontal parameters and microflora in gingival crevicular fluid before and after treatment were compared between the 2 groups.Results:After treatment,both groups showed improvements in teeth,and the gingival index[(0.13±0.05)mm,(0.24±0.08)mm],plaque index[(0.83±0.08)points,(1.24±0.25)points],probing depth[(3.52±0.18)mm,(4.23±0.29)mm],clinical attachment loss[(4.37±0.25)mm,(5.03±0.37)mm]and crevicular bleeding index[(1.88±0.17)points,(2.24±0.25)points]were lower in the observation group(P<0.05).The levels of total flora,G-and G+flora in the observation group after treatment were lower than those in the control.The levels of Streptococcus Gordonii,Streptococcus blastoides,Prevotella nigricans and porphyromonas gingivalis in the observation group after treatment were[(0.21±0.07)×104·mL-1,(0.17±0.04)×104·mL-1,respectively.(0.71+0.08)×104·mL-1,(0.31-0.09)×104·mL-1 respectively.]significantly lower than those in the control[(0.95-0.09)×104·mL-1,(0.89-0.06)×104·mL-1,(1.14±0.10)×104·mL-1,(0.86±0.12)×104·mL-1,respectively],the difference was statistically significant(P<0.05).Conclusion:Periodontal tissue regeneration combined with Cervitec gel has a good effect in the treatment of periodontitis.After treatment,the level of the bacteria community in the gingival crevicular fluid and the periodontal examination parameters are significantly improved,which is worthy of application.
