Dental caries, a widespread oral health issue, results from a complex interplay of factors including behavior, hygiene, diet, and socio-demographic aspects. While preventive measures are available, it remains prevalent globally, affecting numerous teeth per individual. Improved oral hygiene practices and increased awareness have led to a reduction in caries prevalence. However, rising sugar consumption exceeds dietary guidelines, contributing to the problem.

Surveillance of oral health in the early middle age group is standard, allowing decision-makers to assess the impact of caries and oral health care provision.
