Clinical Trial Summary

This study evaluates the effectiveness of an intervention, non-surgical periodontal treatment (SPR), in patients with poorly controlled type 2 diabetes mellitus and moderate-severe periodontal disease aimed at reducing HbA1c levels at 12 months compared with the usual practice in Primary Health Care.

Description:

Design: Pragmatic cluster randomized clinical trial with 12 months follow-up. Unit of randomization: dentist. Setting: Primary Health Care Centers in one Spanish region (Madrid) Population: Patients ≥ 35 years of age with moderate-severe periodontal disease and diagnosed with type 2 diabetes with por control (HbA1c > 7,5). N=288 patients (144 in each arm) will be recruited by dentist before randomization. Intervention: Both groups will receive education on oral hygiene measures. The experimental group will receive the non-surgical periodontal treatment at the beginning of the study and the control group at the end of the study.

Intervention

Procedure:
• Non-surgical periodontal treatment: Scaling and root planing (SRP)
Removal of dental plaque and dental calculus from the surface of a tooth, from the surface of a tooth apical to the gingival margin accumulated in periodontal pockets, or from the surface coronal to the gingival margin.

Other:
• Oral hygiene instructions
Education for individual health regarding peridontal disease and its association with diabetes, as well as oral hygiene instructions that include the modified Bass technique, use of interproximal brushes and dental floss

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Glycated Hemoglobin A (HbA1c)	Products of non-enzymatic reactions between GLUCOSE and HEMOGLOBIN A, occurring as a minor fraction of the hemoglobin components of human erythrocytes. Glycated hemoglobin A is used as an index of the average blood sugar level over a lifetime of erythrocytes.; Glycated hemoglobin (A1C) goals in patients with diabetes should be tailored to the individual, balancing the demonstrated benefits with regard to prevention and delay in microvascular complications with the risk of hypoglycemia. A reasonable goal of therapy might be an A1C value of =7.0 percent for most medication-treated patients (using an assay aligned to the Diabetes Control and Complications Trial in which the upper limit of normal is 6.0 percent). Glycemic targets are generally set somewhat higher (eg, <8 percent) for older adult patients and those with comorbidities or a limited life expectancy and little likelihood of benefit from intensive therapy.	Change from baseline HbA1c score at 6 and 12 months
Secondary	Probing depth	The measured distance from the free end of the gingival margin to the bottom of the periodontal pocket. Measurement in milimetres. Depths greater than 3 mm can be associated with "attachment loss" of the tooth to the surrounding alveolar bone, which is a characteristic found in periodontitis.	basal measurement, at 6 and 12 months
Secondary	Glomerular filtration	The volume of water filtered out of plasma through glomerular capillary walls into Bowman's capsules per unit of time	basal measurement, at 6 and 12 months
Secondary	Quality of life of patients: EuroQol 5D-5L questionnaire	The descriptive system comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The patient is asked to indicate his/her health state. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state. The EQ VAS records the patient's self-rated health on a vertical visual analogue scale, where the endpoints are labelled 'The best health you can imagine' and 'The worst health you can imagine'. The VAS can be used as a quantitative measure of health outcome that reflect the patient's own judgement. Each of the 5 dimensions comprising the EQ-5D descriptive system is divided into 5 levels of perceived problems: 1: no problem. 2: slight problems 3: moderate problems. 4: severe problems. 5: extreme problems	Basal measurement, at 6 and 12 months
Secondary	Physical activity (IPAQ questionnaire)	IPAQ was developed for comparable and valid measures of physical activity within and between countries, across various life domains. Three levels are proposed: Category 1: Low: This is the lowest level of physical activity. Those individuals who not meet criteria for categories 2 or 3 are considered low/inactive. Category 2: Moderate: Any one of the following 3 criteria: 3 or more days of vigorous activity of at least 20 minutes per day; 5 or more days of moderate-intensity activity or walking of at least 30 minutes per day; 5 or more days of any combination of walking, moderate-intensity or vigorous intensity activities achieving a minimum of at least 600 MET-min/week.; Category 3: High: Any one of the following 2 criteria: Vigorous-intensity activity on at least 3 days and accumulating at least 1500 MET-minutes/week; 7 or more days of any combination of walking, moderate-intensity or vigorous intensity activities achieving a minimum of at least 3000 MET-minutes/week	Basal measurement, at 6 and 12 months
Secondary	Diet questionnaire (MEDAS)	The MEDAS is a 14-item questionnaire that asks participants to report the usual frequency of consumption or the amount consumed of 12 main components of MedDiet and two eating habits related to MedDiet. Each of the 14 items is scored 1 or 0, depending on whether the participants adhere to each MedDiet component or not. If these conditions were not met, an item was assigned a score of 0. The resulting MedDiet score of MEDAS varied from 0 to 14. Photographs of portions and portion sizes were used, as appropriate, to facilitate completion of MEDAS TOTAL SCORE: < 9 low adhesion; > = 9 good adhesion	Basal measurement, at 6 and 12 months
Secondary	Therapeutic adherence questionnaire (Morisky-Green)	It consists of a series of four contrast questions with dichotomous answer (yes / no), which reflects the patient's behavior regarding compliance. It is intended to assess whether the patient adopts correct attitudes regarding the treatment for his illness; It is assumed that if the attitudes are incorrect, the patient is non-compliant. It has the advantage of providing information on the causes of the breach. The patient is considered as compliant if he answers the four questions correctly.	Basal measurement, at 6 and 12 months
Secondary	Cost-utility	The calculation of benefits will be made in the form of QALYs accounting for the total profit in profits, measured with the EuroQol 5D-5L in the intervention group	At 12 months
Secondary	Gingival Recession	Exposure of the root surface when the edge of the gum (GINGIVA) moves apically away from the crown of the tooth. Measurement in milimetres. Greater gingival recession can be associated with "attachment loss" of the tooth to the surrounding alveolar bone, which is a characteristic found in periodontitis.	basal measurement, at 6 and 12 months
Secondary	Clinical attachment level	The distance from the cementoenamel junction to the bottom of the periodontal pocket. Measurement in millimetres. Greater clinical attachment level can be associated with "attachment loss" of the tooth to the surrounding alveolar bone, which is a characteristic found in periodontitis.	basal measurement, at 6 and 12 months
Secondary	Gingival Probing bleeding	Measured as the percentage of sites with blood present at the probing (present: if it occurred within 30 seconds of the probing. Absent: if no bleeding occurred). Greater gingival probing bleeding can be associated with "Inflammation of gum tissue", which is a characteristic found in periodontitis.	basal measurement, at 6 and 12 months
