Enamel hypoplasia can be triggered by a deficiency in which of the following elements?
Show answer Hide answer
Answer: A. Vitamin B and C
Explanation
Specific vitamin shortages directly disrupt the normal amelogenesis process. Vitamins B and C play critical roles in matrix formation. Inadequate levels prevent ameloblasts from properly depositing enamel matrix proteins. Amelogenesis requires continuous systemic nutritional support during tooth development stages. Vitamin deficiencies compromise cellular metabolism within developing dental tissues. Enamel hypoplasia represents a permanent structural developmental defect in teeth.
Malnutrition during childhood frequently manifests as structural enamel defects later. Identifying these defects helps clinicians estimate the exact developmental timeline. Preventative nutritional guidance reduces the incidence of developmental dental anomalies. Calcium is primarily responsible for mineralization rather than matrix formation. Vitamin C alone is insufficient compared to combined deficiencies. Vitamin B alone does not cover all required metabolic pathways.
