Description
Summary:International Journal of Paediatric Dentistry 2011; 21: 185–191 Aims.  This study aimed to investigate the dental caries status and salivary properties in 3‐ to 15‐year‐old children/adolescents. Methods.  The sample was split in two groups: asthma group (AG), composed of 65 patients who attended Public Health Service; asthma‐free group (AFG), composed of 65 nonasthmatic children/adolescents recruited in two public schools. Stimulated salivary samples were collected for 3 min. Buffering capacity and pH were ascertained in each salivary sample. A single trained and calibrated examiner (kappa = 0.98) performed the dental caries examination according to WHO criteria. Results.  The AFG showed salivary flow rate (1.10 ± 0.63 mL/min) higher (P = 0.002) than AG (0.80 ± 0.50 mL/min). An inverse relationship was observed between asthma severity and salivary flow rate (Phi coefficient, rφ: 0.79, P = 0.0001). Children with moderate or severe asthma showed an increased risk for reduced salivary flow rate (OR: 17.15, P  0.05) and drug type (P > 0.05) with salivary flow rate. Buffering capacity was similar in both groups. No significant differences were encountered in dental caries experience between AFG and AG groups. Conclusions.  Although asthma can cause reduction in flow rate, the illness did not seem to influence dental caries experience in children with access to proper dental care.
