Effect of secondary subgingival scaling for patients with parodontopathy and its influence on probing depth, attachment loss, sulcus bleeding index and plaque index

  Objective  To investigate the effect of secondary subgingival scaling on periodontal disease and its influence on probing depth (PD), attachment loss (AL), sulcus bleeding index (SBI) and plaque index (PLI).

  Methods  Totally 100 patients with periodontal disease were divided into control group (n=50) with valvuloplasty and observation group (n=50) with secondary subgingival scaling according to the ball method. Changes of PD, AL, SBI and PLI after treatment were compared between the two groups.

  Results  The levels of PD, AL, SBI and PLI in both groups decreased significantly at 3 and 6 months after operation (P < 0.05), while there were no significant differences in the levels of PD, AL, SBI and PLI between the two groups at 3 and 6 months after operation (P>0.05). The alveolar bone resorption rate of the observation group was 90.0%, which had no significant difference when compared to 84.0% of the control group (χ²=0.354, P=0.552). The gingival recession rate of the observation group was 6.0%, which was significantly lower than that 22.0% of the control group (χ²=4.070, P=0.044).

  Conclusion  Secondary subgingival scaling is effective in treating patients with periodontal disease.
