ObjectiveTo investigate the effect of periodontal therapy on plaque index and serum anticardiolipin antibody IgG and IgM in elderly patients with periodontitis and hypertension. Methods47 elderly patients with periodontitis and hypertension from December 2015 to March 2017 were treated with periodontal basic treatment. The changes of periodontal probing depth (PD), sulcus bleeding index (BI), clinical attachment level (CAL), plaque index (PLI) and dental loosening were compared before and after treatment. The serum anticardiolipin antibody IgG (ACA-IgG), IgM (ACA-IgM), serum C reactive protein (CRP) and interleukin-6 (IL-6) and clinical therapeutic effect were observed before and after comparative treatment. ResultsThe PLI, BI, PD and CAL values of patients decreased continuously with the prolongation of treatment time , and the difference was statistically significant before and after treatment (P＜0.05). The degree of tooth loosening decreased, and there was a significant difference in the degree of tooth loosening before and after treatment (P＜0.01). After 6 months of treatment, the proportion of patients without tooth loosening was 82.98%, and there were no third degree loosening. The levels of ACA-IgG, ACA-IgM, CRP and IL-6 in the serum of the patients were significantly decreased compared with those before treatment (P＜0.05). The total effective rate of patients was 93.62%. ConclusionPeriodontal treatment for elderly patients with periodontitis and hypertension can improve the condition of periodontitis and tooth loosening, relieve the pain of the patients and help to improve the patient’s hypertension.
