Effect of dental treatment on the lung function of children with asthma

In this preliminary study, the authors evaluated whether dental treatment can trigger a reaction in the hyperactive airways of children with asthma, thereby affecting lung function. They also examined the variables, if any, that predict a change in lung function in relation to dental treatment. They tested the lung function of 57 6- to 18-year-old subjects with histories of active asthma, using spirometry before, immediately after and 30 minutes after routine dental treatment. Results revealed a statistically significant decrease (P < .05) in lung function and a clinically significant decrease in lung function in approximately 15 percent of the subjects.
