Systematic Review Conclusion
A possible causal relationship exists between caries in primary dentition and secondhand smoke (SHS), whereas a similar relationship for permanent dentition remains unclear.
Critical Summary Assessment
In this systematic review of 15 high-quality observational studies, the authors found that the results of 10 studies showed a weak to moderate relationship between caries in primary dentition and SHS, and the results of five studies showed a weak relationship for permanent dentition.
