Evidence that periodontal treatment improves diabetes outcomes: a systematic review and meta‐analysis

Abstract

Context: The effect of periodontal therapy on diabetes outcomes has not been established. Objective: This update examines the effect of periodontal treatment on diabetes outcomes. Data sources: Literature since October 2009 using MEDLINE. Study eligibility criteria: Published RCT s including periodontal therapy for diabetic subjects, a metabolic outcome, an untreated control group, and follow‐up of 3 months. Data extraction: Pre‐defined data fields, including study quality indicators were used. Data synthesis: A search revealed 56 publications of which 9 met inclusion criteria. Mean change of HbA1c from baseline was compared across treatment groups. Pooled analysis was based on random effects models. Results: A meta‐analysis indicated a mean treatment effect of −0.36% HbA1c (CI −0.54, −0.19) compared to no treatment after periodontal therapy (p < 0.0001). Heterogeneity tests revealed only minimal evidence of publication bias (I2 = 9%). Limitations: Small sample size and high risk of bias remain problematic for studies of this type. Periodontal therapy varied considerably. Conclusion: The modest reduction in HbA1c observed as a result of periodontal therapy in subjects with type 2 diabetes is consistent with previous systematic reviews. Despite this finding, there is limited confidence in the conclusion due to a lack of multi‐centre trials of sufficient sample size are lacking.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
