  1. Nutrition in dentistry

  2. Vitamins

  3. Vitamin B1 • thiamine • function – coenzyme (oxidative decarboxylation...) Symptoms • Deficiency: beri-beri • exudative (wet) form – heart insufficiency, oedema • dry form – polyneuritis, Wernicke-Korsakoff syndrome • B1 deficiency – chronic alcoholism

  4. Beri-beri

  5. Vitamin B2 • riboflavin • function – coenzyme (redox reactions... ) Oral signs and symptoms • Deficiency: angular cheilosis, atrophy of filliform papilae, shiny red lips, sore tongue Other symptoms • conjuctivitis, dermatitis, anaemia, mental retardation

  6. Vitamin B2 angular cheilosis conjuctivitis atrophy of filliform papilae

  7. Vitamin B3 • niacin, nicotinic acid • function – coenzyme (redox reactions...) Oral signs and symptoms • Deficiency: angular cheilosis, mucositis, stomatitis, oral pain, ulceration, denuded tongue, glositis, glossodynia, red and swollen tip or borders of tongue, dorsum is dry and smooth Other symptoms • Deficiency: Pelagra (3D) – dermatitis, diarhea, dementia

  8. cheilosis mucositisglositis glossodynia Pelagra - dermatitis

  9. Folic acid • Tetrahydrofolic acid • function – biosynthesis of purins → DNA Oral signs and symptoms • Deficiency: angular cheilosis, mucositis, stomatitis, oral pain, sore or burning mouth, increased risk of candidiasis, inflamed gingiva, glossitis, glossodynia, red and swollen tips or borders of tongue, aphtous ulcers Other symptoms • Deficiency: macrocytic anaemia, diarhea, weight loss

  10. candidiasis inflamed gingiva aphtous ulcers macrocytic anaemia macrocytes normal RBC

  11. Vitamin B6 • pyridoxine • function – coenzyme (amino acid metabolism...) Oral signs and symptoms • Deficiency: angular cheilosis, sore or burning mouth, glossitis, glossodynia Other symptoms • Deficiency: neuritis, diarhea, dermatitis, anaemia, seizures

  12. Vitamin B12 • cyanocobalamine • function – coenzyme, folate metabolism... Oral signs and symptoms • Deficiency: angular cheilosis, mucositis, stomatitis, sore or burning mouth, haemorrhage gingiva, halitosis, dysplasia of oral mucosa, loss of taste, oral pain, ulceration, glossitis, glossodynia, red tongue, xerostomia, aphtous ulcers Other symptoms • Deficiency: pernicious anaemia, neurological signs

  13. halitosis xerostomia

  14. Vitamin C • ascorbic acid • function – reducing agent, antioxidant, collagen biosynthesis, iron absorption, immunity... Oral signs and symptoms • Deficiency: Scurvy – red swollen gingiva, gingival friability, periodontal destruction, increased tooth mobility and exfoliation, sore burning mouth, soft tissue ulceration, increased risk of candidiasis, malformed teeth (inadequate dentine) Other symptoms • Deficiency: fragility of vessel wall, impaired development of bones

  15. Scurvy

  16. Vitamin A • retinol • function – vision, growth and differentiation of epitels Oral signs and symptoms • Deficiency: impaired tissue healing and regeneration, desquamation of oral mucosa, keratosis, increases risk of candidiasis, gingival hypertrophy and inflammation, leukoplakia, decreased taste sensitivity, xerostomia, disturbed enamel development, increased caries risk • Excess: impaired wound healing Other symptoms • Deficiency: night blindness, xerophtalmia, mucosa dryness • Excess: hepatosplenomegalia, anaemia, hair loss

  17. desquamation of oral mucosakeratosis gingival hypertrophy and inflammationm

  18. leukoplakiaxerostomia disturbed enamel developmentcaries

  19. Vitamin D • calcitriol • function – hormone, Ca metabolism Oral signs and symptoms • Deficiency: osteoporosis, osteomalacia, rickets, incomplete mineralisation of teeth • Excess: pulp calcification, enamel hypoplasia Other symptoms • Deficiency: osteoporosis, osteomalacia, rickets • Excess: Ca mobilisation from bones, kidney stones
