Weak evidence suggests scaling and root planing may help people with diabetesimprove glycemic control

Jan Clarkson PhD, FDS RCS; Joseph Matthews DDS; Asbjorn Jokstad DDS, Ph.D .


Systematic Review Conclusion

Periodontal treatment may improve glycemic control in adults with poorly controlled diabetes, although the research basis for this statement is not robust.

Critical Summary Assessment

This systematic review followed a clear protocol for locating and assessing all pertinent studies. The studies were of variable quality, with only one randomized controlled trial considered to be of high quality. The review does not provide a confident basis for determining whether scaling and root planing can improve glycemic control in people with diabetes.
