Effect of low 1evel laser treatment on metabolic control and high-sensitivity C-reactive protein of type 2 diabetes mellitus combined chronic peridontitis patients / 国际生物医学工程杂志

ABSTRACT

Objective To investigate the effect of low 1evel laser treatment (LLLT) on periodontal clinical index,high-sensitivity C-reactive protein (hs-CRP) and metabolic control in patients of type 2 diabetes mellitus combined chronic peridontitis.Methods Nighty patients with type 2 diabetes combined chronic peridontitis were divided into three groupsinitial periodontal therapy (group A),initial therapy combined with LLLT (group B) and control group (group C).The periodontal clinical parameters including periodontal probing depth (PD),clinical attachment loss (CAL),sulcus bleeding index (SBI),hs-CRP,HbA1c and fasting blood glucose (FBG) were tested before and at three months after therapy.Results The periodontal clinical parameters (PD,CAL,SBI) and hsCRP in group A and B improved significantly compared with that of group C after therapy (P＜0.05),with group B had more significant difference (P＜0.01).For the levels of HbA1c and FPG,group A and B showed downtrend,and more obvious outcome was detected in group B (P＜0.05).Conclusions LLLT can effectively improve periodontal status,hs-CRP levels and metabolic control of patients with type 2 diabetes combined with chronic peridontitis,and thus to prevent the occurrence of diabetes complications.
