Individuals exposed to the same risk factors may be more or less
susceptible to dental caries. After 10 years of research it is
accepted that genes are involved and that the genetic contribution
to increased caries prevalence is 40%. Genetic variation in enamel
and saliva proteins, immune response and taste preferences interact
with other risk factors and may thereby influence the caries
risk. A high prevalence of dental erosion is reported. In some individuals
erosive lesions will develop despite minimal acid exposure.
In others no damage will occur despite extensive acid exposures.
This has been observed in individuals with high consumption of
acidic drinks, with reflux/ self-induced vomiting and wine tasters.
The occurrence and severity of erosive lesions have been associated
with polymorphisms in enamel genes.
