Scientific titlePeriodontal treatment for improving glycaemic control in diabetic patients: a randomised controlled trial
Study acronymDIAPERIO
Study hypothesisPeriodontal treatment could lead to an improvement in HbA1c levels in metabolically unbalanced diabetic patients suffering from periodontitis.

We will therefore test the null hypothesis that periodontal treatment does not reduce the HbA1c level in metabolically unbalanced diabetic patients suffering from periodontitis.

Secondary objectives of this study are to assess among metabolically unbalanced diabetic patients suffering from periodontitis:
1. Whether periodontal treatment could lead to an improvement in fructosamin levels
2. Whether periodontal treatment could lead to an improvement in life quality
3. Whether periodontal treatment is safe and effective
Ethics approval(s)1. Committee for Protection of Research Subjects (Comité de Protection des Personnes [CPP]), Sud-Ouest Outre-Mer I, approved on 23/02/2009
2. Sanitary Safety in Health Products Agency (Agence française de sécurité sanitaire des produits de santé [AFSSAPS]), approved on 12/02/2009 (ref: 2008-A01467-48)
3. Advisory Committee for Data Processing in Health Research (Comité consultatif sur le traitement de l'information en matière de recherche dans le domaine de la santé [CCTIRS]), approved on 15/01/2009
ConditionDiabetes mellitus, periodontal disease
InterventionPeriodontal treatment will include non-surgical scaling and root planing, systemic antibiotherapy, oral health instructions and antiseptic prescription. It will be performed within 10 days after inclusion for the treatment group, and after 100 days after inclusion for the control group.
Intervention typeOther
Primary outcome measureDifference between 3-month and baseline HbA1c levels.
Secondary outcome measuresDifference between 3-month and baseline values of the following:
1. Fructosamin levels
2. Quality of life (SF-36® Health Survey)
3. Adverse clinical outcome event
4. Periodontal Inflamed Surface Area (PISA)
