Abstract
Very little is known about whether parental substance-use disorders (SUDs) affect the prevalence of dental abnormalities among their offspring. This study examined the prevalence of various dental abnormalities in sons of fathers with SUDs (the high average risk, or HAR, group) versus the prevalence of these abnormalities among sons of fathers without SUDs (the low average risk, or LAR, group). A total of 385 sons and their families were comprehensively assessed at five different ages, 10–12, 12–14, 16, 19, and 22. All of these participants were participating in an ongoing longitudinal NIDA-funded center study (CEDAR) evaluating the etiology of SUDs, in collaboration with the University of Pittsburgh Dental School. The data from this study provide evidence that paternal SUDs (HAR vs. LAR status) is associated with poor dental condition, poor oral hygiene, a greater need for dental treatment, and inadequate levels of dental treatment utilization.
