Does the periodontal health of thalassemia major patients have an impact on the blood lipid profiles? A preliminary report.

Cardiac symptoms and premature death from cardiac causes are still suggested to be a major problem in thalassemic patients. One of the main reasons for the cardiovascular events in thalassemia major (TM) patients has suggested having iron overload, in addition to other reasons such as hypoxia, abnormal lipoproteins levels, atherosclerotic conditions, etc. This study aims to investigate whether the periodontal health has an impact on the blood lipid levels. Twenty-four TM patients and sex-matched controls (C) enrolled to this study. The measurements of the periodontal parameters (gingival index, plaque index, bleeding on probing, probing depth, and clinical attachment level) were recorded. Besides, in venous blood samples the lipid profile was investigated. All of the periodontal parameters were significantly higher in TM group than in C group (P<0.05). Triglyceride and cholesterol/high density lipoprotein ratio had significant positive correlations with the periodontal parameters (P<0.05). Multiple regression analyses present significant associations between gingival index, plaque index scores, and the cholesterol/high density lipoprotein ratio (P<0.001). Our study results showed that the lipid profile of TM patients might be affected by their periodontal health. Further studies are needed to determine the lipid profile involvement magnitude and the cardiovascular disease risk caused by the periodontal health of TM patients.

Anti-inflammatory cytokines in gingival crevicular fluid in patients with periodontitis and rheumatoid arthritis: a preliminary report.

Cytokines which are produced by host cells play an important role in pathogenesis both rheumatoid arthritis (RA) and chronic periodontitis (CP). In this study, we aim to investigate the levels of Interleukin (IL)-4 and IL-10 in gingival crevicular fluid (GCF). Seventeen patients with CP, 17 patients with RA and 17 healthy controls (HC) were included. The RA group was divided into two groups according to gingival sulcus depths (RA-a: PD < or =3mm, (n=12), RA-b: PD>3mm, (n=5)). For each patient, clinical parameters were recorded. The GCF samples were evaluated by enzyme-linked immunosorbent assay (ELISA) for IL-4 and IL-10 levels. IL-4 levels in the RA-a, RA-b and CP subjects were significantly lower compared to the HC subjects (p<0.05). The mean level of IL-4 in RA-b group was significantly higher than that in CP group (p<0.05). IL-10 mean level in the HC group was higher than those in the other groups (p<0.05). In the RA-a group, higher IL-10 level was found compared to the CP patients (p<0.05). Within the limitations of this preliminary report, it can be concluded that the initiation and progression of periodontal inflammation may be due to a lack or inappropriate response of the anti-inflammatory cytokines in both CP and RA.

The comparison of various oral hygiene strategies in neuromuscularly disabled individuals.

BACKGROUND: This study aims to investigate the effect of various oral hygiene strategies on the symptoms of inflammation in neuromuscularly disabled patients and to define the optimum hygiene method. METHODS: Fifty-nine neuromuscularly disabled participants, suffering from cerebral palsy, were randomly divided into five groups as follows: Group M: manual toothbrush (n=14), Group E: electrically powered toothbrush (n=9), Group MC: manual toothbrush and chlorhexidine gluconate (CHX) spray (n=13), Group EC: electrically powered toothbrush and CHX spray (n=9), and Group C: CHX spray (n=14). The oral hygiene applications were provided by the parents and staff. At baseline and after 21 days the plaque index (PI), the gingival index (GI), and bleeding on probing (BOP) were recorded. RESULTS: In intra-group comparisons of the pre- and post-application scores, in all groups the PI and GI scores and BOP percentages, except in Group C, were found significantly different (p<0.05). There were significant differences among the post-application scores, between Group M and Group E and between Group C and Group E in PI scores; between Group C and Group E the difference in GI scores were found statistically significant (p<0.05). CONCLUSIONS: Although all oral hygiene strategies reduced plaque and gingival inflammation, the results of our study suggested the electrically powered toothbrush could be more recommendable to neuromuscularly disabled people in these strategies, while the combined procedures appeared to be neither beneficial nor favorable.
