Some studies report that specific treatment of periodontal
disease in diabetic patients may improve their glycemic
control. Nevertheless, the evidence currently available
does not provide sufficient information on which to
confidently base any clinical recommendations (10, 11,
12). This has motivated the preparation of a randomized
and controlled trial which will provide evidence- based
recommendations for clinicians (DIAPERIO trial, whose
definitive results will be published in 2013) (12).
The relationship between DM and dental caries has been
studied, but it has not been possible to establish a clear
association between these conditions. The results obtained
vary considerably depending on the study; some
of them found a higher prevalence of caries in diabetic
patients (13, 14), some found lower (15), while other reported
no difference (16).
