Abstract:Objective To observe the effect of conventional periodontal therapy on type 2 diabetes with periodontitis, and to analyze the changes in blood glucose and serum biochemical indicators of patients.Methods A total of 114 patients with type 2 diabetes and periodontitis who underwent intervention treatment in our hospital from March 2017 to June 2019 were selected as the analysis objects. They were divided into two groups according to the random number table method. One group was the control group (57 cases), and the other group was the study group (57 cases). The former group was treated with conventional therapy, and the latter group was treated with periodontal therapy based on conventional therapy. The periodontal clinical parameters of the two groups of patients, periodontal pocket bottom to gingival margin (PD), percent bleeding after exploration (BOP), bleeding index (BI), and periodontal pocket to enamel cementum boundary (CAL), were compared before and after treatment; fasting blood glucose (FBG) and glycated hemoglobin (HbAlc) levels before and after treatment and analysis of serum biochemical indicators such as triglycerides (TG), blood calcium (Ca), etc., were detected.Results There were no differences in the levels of PD, PLI, BOP, CAL, HbAlc, T-Bil, FBG, Ca, P, Ca/P, TG, lipoprotein and ApoAl before treatment (P > 0.05). The levels of BI, PD, BOP, PLI, CAL, HbAlc, calcium to phosphorus, serum P and TG decreased, ApoA1 and T-Bil levels increased (P < 0.05), but there was no difference in FBG levels (P > 0.05). Compared with the control group, the BI, PD, BOP, PLI, CAL, HbAlc, calcium-phosphorus ratio, serum P, TG levels decreased, ApoA1 and T-Bil levels increased (P < 0.05), but no difference in FBG levels. (P > 0.05).Conclusion Periodontal basic treatment can improve serum calcium-phosphorus ratio, blood lipid metabolism level, glycated hemoglobin, and periodontal parameters in patients with type 2 diabetes and periodontitis, which can be promoted and applied clinically.
