Abstract Objective. The aim of this study was to evaluate periodontal status and microbiological conditions in young adults with insulin-dependent diabetes (IDDM) in comparison with age- and sex-matched non-diabetic controls. Materials and methods. Forty-one patients, 18-24 years of age with IDDM since childhood, were examined and the results were compared to those of a group of 41 sex- and age-matched non-diabetic controls. According to the HbA(1c) %, the group of diabetic patients was divided into two groups, with good or poor metabolic control. Results. Periodontal health, expressed in probing pocket depths and marginal bone loss, was fairly good in all patients. Fifty per cent of the patients in the study and control groups displayed probing pocket depths ≥4 mm, mostly pocket depths 4 mm. These findings were also equally distributed among the patients with good and poor metabolic control. No significant differences were found between the groups regarding bleeding on probing, but in the number of sites with excessive bleeding the study group exhibited higher scores than the healthy controls. Different microbiological species were equally distributed between the groups. Conclusion. Neither periodontal nor microbiological status in young adults with IDDM differs from that of healthy controls.

The aim of the study was to analyze how metabolic control of type 1 diabetes is related to clinical and microbiological periodontal parameters.
The study involved 56 subjects aged from 19 to 50 years divided into 2 groups: healthy subjects (the H group), and diabetic (type 1 diabetes) patients with chronic untreated generalized periodontitis (the DM group). The glycosylated hemoglobin value (HbA1c) was determined using the UniCel DxC 800 SYNCHRON System (Beckman Coulter, USA), and the concentration in blood was measured by the turbidimetric immunoinhibition method. A molecular genetic assay (Micro-IDent plus, Germany) was used to detect periodontopathogenic bacteria in plaque samples. Periodontitis was confirmed by clinical and radiological examination.
Fusobacterium nucleatum, Capnocytophaga species, and Eikenella corrodens were the most frequently found bacteria in dental plaque samples (77.8%, 66.7%, and 33.4%, respectively), whereas Aggregatibacter actinomycetemcomitans was identified 40.7% less frequently in the DM group than in the H group. The strongest relationship was observed between the presence of 2 periodontal pathogens – F. nucleatum and Capnocytophaga spp. – and poorer metabolic control in type 1 diabetes patients (HbA1c) and all clinical parameters of periodontal pathology.
Periodontal disease was more evident in type 1 diabetic patients, and the prevalence of periodontitis was greatly increased in subjects with poorer metabolic control.

ABSTRACT: The present study aimed to investigate the effect of β-anhydroicaritin on the expression levels of tumor necrosis factor (TNF)-α and matrix metalloproteinase (MMP)-3, and the pathological changes in the periodontal tissue of diabetic rats. Male Wistar rats (n=40; three months old) were randomly divided into four groups: Normal control group, diabetes group, diabetes + β‑anhydroicaritin group and diabetes + urate group, (n=10 in each group). Following an overnight fast, diabetes was induced by intraperitoneal injection of streptozocin. The rats were maintained for 12 weeks and the blood sugar, urine sugar and body weight were assessed in week 12. Histological changes of the periodontal tissues were observed by hematoxylin and eosin staining, and the expression levels of TNF‑α and MMP‑3 were observed by immunohistochemistry. Following 12 weeks, the TNF‑α grey value in the diabetes group was significantly lower compared with that in the control group (P<0.05), while no significant difference was observed between TNF‑α levels in the diabetes + β‑anhydroicaritin group, diabetes + urate group and the control group (P>0.05). However, TNF‑α levels in the diabetes + β‑anhdroicaritin group and diabetes + urate group were significantly higher compared with those in the diabetes group (P<0.05), and those in the diabetes + β‑anhydroicaritin group were lower compared with those in the diabetes + urate group (P<0.05). The MMP‑3 grey value in the diabetes group was significantly lower compared with that in the control group (P<0.05), while no significant difference was observed between MMP‑3 levels in the diabetes + β‑anhydroicaritin group, diabetes + urate group and the control group (P>0.05). However, MMP‑3 levels the diabetes + β‑anhydroicaritin group and diabetes + urate group were significantly higher compared with those in the diabetes group (P<0.05), and those in the diabetes + β‑anhydroicaritin group were lower compared with those in the diabetes + urate group (P<0.01). β‑anhydroicaritin normalized the expression levels of TNF‑α and MMP‑3 in the periodontal tissue of diabetic rats and led to the recovery of the changes in the morphological structure of the periodontal tissue.

We evaluated the periodontal conditions in patients with type 2 diabetes mellitus compared to metabolically healthy controls, and determined whether periodontal interleukin genotypes and microorganisms differed between participants with and without type 2 diabetes mellitus.
From April 2011 to July 2012, we prospectively enrolled healthy controls and patients with type 2 diabetes mellitus. Evaluation included assessment of medical and periodontal findings. We also recorded the presence of several interleukin gene variants and specific microorganisms, both available through commercially available diagnostic kits. Statistical significance was tested by the chi-square test and student's t-test.
We enrolled 52 patients with type 2 diabetes mellitus and 52 healthy controls. Compared with controls, periodontal disease was significantly more severe in patients with type 2 diabetes mellitus for the following: plaque index, bleeding on probing, pocket probing depth, clinical attachment loss, severe periodontal destruction (i.e., clinical attachment loss ≥ 5 mm), and number of teeth. However, statistical analysis failed to detect significant differences with respect to the periodontal-related interleukin genotypes (p ≥ 0.58) or the selected oral microbiota (p ≥ 0.15).
Based on these results, it may be assumed that chronic periodontitis in patients with type 2 diabetes mellitus is most strongly associated with inadequate oral hygiene. Periodontal interleukin genotypes and differences in oral microbiota seem to play a subordinate role.
