Oral health of patients with cystic fibrosis and their siblings.

Caries prevalence, oral hygiene index, submandibular gland hypertrophy, occlusion, dental hypoplasia, and 
staining of permanent teeth were evaluated in 63 patients with cystic 
fibrosis (CF) who were maintained on a regimen of broad-spectrum antibiotics 
and oral pancreatin, and the findings were compared with those of 
their near- aged siblings. Gland hypertrophy and dental staining were increased 
in patients with CF whereas caries was significantly decreased. No other 
significant differences were found.
