Which vitamin deficiency is most directly associated with scurvy and impaired wound healing in the oral cavity?
Answer: Vitamin C
Vitamin C (ascorbic acid) deficiency causes scurvy, characterized by impaired collagen synthesis, bleeding gums, and poor wound healing.
A patient presents with smooth, shiny tongue and angular cheilitis. Which nutritional deficiency is most likely responsible?
Answer: Iron deficiency
Iron deficiency anemia commonly manifests as glossitis (smooth, pale tongue) and angular cheilitis due to impaired epithelial cell turnover.
Which carbohydrate characteristic most significantly increases cariogenic potential?
Answer: High frequency of consumption
Frequent sugar consumption prolongs acid exposure time on enamel, dramatically increasing caries risk more than total sugar quantity alone.
Which dietary monosaccharide is most readily fermented by Streptococcus mutans to produce lactic acid?
Answer: Glucose
Glucose is the primary substrate for glycolysis in S. mutans, producing lactic acid that demineralizes enamel.
A dental hygienist counseling a patient on caries prevention should recommend limiting intake of which type of food between meals?
Answer: Sticky fermentable carbohydrates
Sticky fermentable carbohydrates adhere to tooth surfaces and are slowly broken down, prolonging acid exposure and caries risk.
Calcium and phosphate in the diet support remineralization of early carious lesions primarily through which mechanism?
Answer: Replenishing mineral ions lost from enamel
Dietary calcium and phosphate provide ions that diffuse back into demineralized enamel, restoring hydroxyapatite crystal structure.
