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 mucosa keratosis gingival hypertrophy and inflammationm

18 leukoplakiaxerostomia disturbed enamel development caries
