To the Editor: Dr Aligne and colleagues1 reported that children who were exposed to passive
smoking were more likely to have dental caries. They concluded that reduction
of passive smoking would lead to better dental health among children. Although
this argument assumes a causal relationship between passive smoking and dental
caries, it is possible that this association is mediated or confounded by
a number of factors.
