Effect of non-surgical periodontal treatment on glycemic control of XXXX with @entity6 : a meta-analysis of randomized controlled trials.

@entity1 @entity164 @entity6 @entity7278
OBJECTIVE: The present study aimed at investigating whether non-surgical periodontal treatment can reduce the Haemoglobin A1c (HbA1c) % level in @entity164 2 @entity6 @entity1 . METHODS: A search of the literature on English publications was performed in Cochrane Central, Medline, ISI Web of Knowledge and EMBASE (until 06 February 2014). An RCT was selected if the subject was @entity164 2 @entity6 @entity1 diagnosed with @entity7278 , and compared HbA1c% change after non-surgical periodontal treatment alone for at least three months of the study duration. Weighted mean difference for pooled data and large sample size strata were calculated. Heterogeneity and publication bias were explored. RESULTS: After the study selection process, only 9 RCTs were suitable. Compared to the control group, the pooled analysis (n=1082) showed -0.27 % (95 % CI:-0.46 % to -0.07 %, p= 0.007) absolute difference in HbA1c % with treatment while studies with sufficient sample size had HbA1c % change of -0.014 % (95 % CI:-0.18 % to 0.16 %, p= 0.87). Publication bias was marginally significant with Egger's teat (p=0.045) but not with Begg's test (p=0.72). CONCLUSION: The moderate reduction in HbA1c after the non-surgical therapy in @entity1 with @entity164 2 @entity6 is consistent with previous systematic reviews. However, more large scale and high-quality RCTs are necessitated to confirm these results.
