Effect of non-surgical periodontal treatment on clinical signs of rheumatoid arthritis.

Background: Several studies have shown the association between periodontitis and rheumatoid arthritis (RA) and some similarities in the pathogenesis of these two diseases but clinical trials which have evaluated the effect of periodontal therapy on clinical signs of active RA are scarce, particularly in Iran. The aim of this study was to evaluate the effect of non-surgical periodontal treatment on the improvement of clinical signs of patients with RA.

Methods: Fifty-six patients with active RA and generalized moderate-to-severe chronic periodontitis were selected and divided into case (periodontal treatment) and control (without periodontal treatment) groups.

Awareness of the effect of fluctuations in female sex hormone levels on periodontal health among obstetricians.

Background: Changes in women's hormonal levels in different periods of their lives, such as puberty, menses, pregnancy, menopause and oral contraceptive use, affect periodontal health. Periodontal status has been associated with adverse pregnancy outcomes. Subsequently, it is important for obstetricians to be aware of the effects of hormones on women's oral health.

The Effect of Brushing with a Soft Toothbrush and Distilled Water on the Incidence of Ventilator-Associated Pneumonia in the Intensive Care Unit.

Background: Ventilator-associated pneumonia (VAP) is a common nosocomial infection, which results in longer hospitalization, increased treatment costs, and higher mortality rates. One major cause of VAP is colonization and microaspiration of oropharyngeal secretions following the formation of dental plaque, which is due to poor oral hygiene and failure to mechanically remove these microorganisms from the teeth. This study was conducted to determine the effect of brushing teeth with distilled water on the incidence of VAP in patients admitted to intensive care unit (ICU).

Effect of 1% Phenytoin Muco-Adhesive Paste on Improvement of Periodontal Status in Patients with Chronic Periodontitis: A Randomized Blinded Controlled Clinical Study.
