Resumen
The relationship between periodontal disease (PD) and diabetes mellitus (DM) is bidirectional, however, there is a need for more evidence regarding basic periodontal treatment on clinical aspects and the presence of bacteria in patients with and without diabetes. Thus, the present study aimed to evaluate the influence of type II diabetes mellitus (DM) on the efficacy of basic periodontal treatment through the clinical and microbiological parameters of saliva. Fifty-one patients were treated between 30 and 65 years of age using the "Full Mouth Disinfection" (FMD) technique, 17 in the diabetic group (DG) and non-diabetic group (NDG). These patients were evaluated before the beginning of the periodontal treatment, at 6 and 12 months after its conclusion. In the periodontal examination, the Bleeding on Probing (BOP), Visible Plaque Index (VPI), Probing Depth (PD), Gingival Recession (RG) and Clinical Attachment Level (CAL) were evaluated. The blood parameters evaluated were fasting glucose and glycated hemoglobin (HbA1C) only for DG. Saliva samples were collected before each periodontal examination. Quantification of the bacterial species Treponema denticola, Porphyromonas gingivalis, and Tannerella forsythia through the real-time polymer chain reaction (PCR) technique was performed. The results showed that the clinical parameters showed a significant improvement for ISS, IPV and PS for both groups, whereas for NCI only for GD (p = 0.023). Regarding the microbiological parameters, there were no differences between the group with diabetes and no diabetes in the evaluated periods, only Tanerella forsythia presented a statistically significant difference in the 12-month period (p = 0.004), with a higher median for the NDD group. In the intragroup analysis, only the DG presented statistical difference for all species evaluated (p <0.05), in which there was reduction after treatment, but increase after the evaluation of 6 months. The species Porphyromonas gingivalis increased significantly after 12 months, in this period of evaluation it obtained median higher than baseline.
