Abstract [en]

The aim of the present case-control study was to investigate dental caries, various caries-related factors as well as gingival condition, in 12- to 16-year-olds with long-term asthma (n = 20) and a matched healthy control group (n = 20). Data on dietary and oral hygiene habits, numbers of mutans streptococci and lactobacilli in saliva were also obtained. The plaque pH drop after a sucrose rinse was measured up to 40 min at 2 approximal tooth sites. A lower salivary flow rate was found in the asthma group compared to the control group (p < 0.05). The mean (± SD) of DFS, including manifest and initial caries, was 4.9 ± 5.5 in the asthma and 1.4 ± 2.3 (p < 0.01) in the control group. Only 1 adolescent in the asthma group was caries free compared to 13 in the control group. Concerning pH in plaque, adolescents with asthma had a lower initial value (p < 0.01) and final pH (p < 0.05) than the control group. The Cariogram data showed that 55% of the subjects in the control group had ‘a high chance of avoiding caries’ compared to 10% in the asthma group (p < 0.01). The asthmatic adolescents had higher numbers of sites with gingival bleeding (p < 0.01). To conclude, adolescents with long-term asthma had a higher total DFS and caries risk (according to Cariogram), decreased salivary rate, more gingival bleeding and lower plaque pH than adolescents without asthma.
