Which of the following groups are at high risk for caries?

• A. Special health care needs
• B. Low socioeconomic and ethno-cultural groups
• C. Suboptimal exposure to topical or systemic fluoride
• D. All of the above

Answer: (D)

High caries risk shows up when protective factors like fluoride protection and regular care are weak, and multiple risk factors are present. Special health care needs can raise risk because medications often reduce saliva flow, daily hygiene can be harder to maintain, and access to routine dental care may be limited. Low socioeconomic and ethno-cultural groups face barriers such as limited access to care, affordability, language or education gaps, and disparities in preventive services, which contribute to higher caries prevalence. Suboptimal exposure to fluoride removes a key protective mechanism—fluoride helps remineralize enamel and inhibits acid production by bacteria, so reduced exposure leaves teeth more vulnerable to decay. When these factors are present together, they collectively place individuals in the high-risk category, making it accurate to say that all of these groups are at high risk for caries.
