Oral health of Chinese people with systemic sclerosis

The aim was to study oral health status, salivary function, and oral features of Chinese people with Systemic Sclerosis (SSc). Chinese people with SSc attending a university specialist clinic were invited for a questionnaire survey and a clinical examination. Ethics approval was sought (UW 08-305). Gender- and age-matched individuals without SSc who attended a university dental hospital were recruited for comparison. Forty-two SSc patients with a mean age of 54.0 +/- 12.2 were examined. This study found no Chinese people with systemic sclerosis were periodontally healthy and many (76%) had periodontal pockets despite most of them (93%) practiced daily tooth-brushing. They all had caries experience (DMFT = 10.5) and many (65%) had untreated decay. Mucosal telangiectasia was a common oral feature (80%). They had lower resting salivary flow rates (0.18 +/- 0.17 ml/min vs. 0.31 +/- 0.21 ml/min; p = 0.003) and pH values (6.90 +/- 0.40 vs. 7.28 +/- 0.31; p < 0.001) and reduced maximal mouth opening (40.1 +/- 6.5 mm vs. 43.6 +/- 7.0 mm) than people without SSc.
