[Periodontal status of Senegalese patients with Sjögren's syndrome. A case control study at the Service of Internal Medicine].

The aim of this study is to compare the periodontal status of patients with Gougerot-Sjögren syndrome (GSS) to healthy subjects in order to investigate the relation between periodontal disease and GSS. To achieve this aim, one hundred and three patients, among whom 36 with primary GSS and 67 with secondary GSS, were selected and compared with one hundred and three (103) control subjects. The hygiene level was evaluated with Silness and Löe plaque index (PI) and inflammation level with Löe and Silness gingival index (GI). Probing depth and clinical attachment loss was measured with Williams periodontal probe. Mean plaque indices were identical for both groups (1.27 +/- 0.1 versus 1.22 +/- 0.1, p = 0.67). Compared with control subjects, the inflammation index scores were significantly higher among SSG patients (IG = 1.1 +/- 0.1 versus 0.44 +/- 0.2, p < 0,001). The logistical regression model applied to the whole sample showed that patients with GSS had a higher risk of developing periodontal disease (IG : OR 5.508, state 95% CI [1.66-9.60] ; PP : OR = 4.51 95% CI [1.692-12.024]). A training program for GSS patients seems essential, in order to manage the deleterious effects of defective oral-dental ground. It would allow convincing patients about the interest of prevention through regular surveillance and care.
