Salivary gland hyperplasia and keratinization disorders are linked with deficiencies in which of the following______________?
Show answer Hide answer
Answer: A. Vit – A
Explanation
Vitamin A is crucial for maintaining the structural integrity of mucosal epithelial tissues. Deficiency leads to squamous metaplasia, keratinization disorders, and glandular atrophy. Salivary gland ducts become obstructed by keratin debris due to this specific vitamin lack. Vitamin A encompasses retinol, retinal, and retinoic acid active compounds. It plays a fundamental role in cellular differentiation, vision, and immune function. Dietary sources include liver, dairy products, and carotenoid-rich dark green vegetables.
Severe deficiency causes xerophthalmia, night blindness, and increased vulnerability to infections. Oral manifestations include dry mucous membranes and altered salivary flow rates. Adequate nutritional intake prevents epithelial breakdown and associated glandular dysfunction. Vitamin B deficiencies typically cause glossitis, angular cheilitis, and various neurological symptoms. Vitamin C deficiency results in scurvy, characterized by defective collagen synthesis and bleeding gums. Vitamin K deficiency primarily impairs blood coagulation and normal clotting factor activation.
