nutritional deficiencies
-biofilm is the initiating factor
-modifies response to biofilm
-most studies completed w/ vitamin C
-modifies the immune response
-oral cavity changes (oral mucosa, lips, tongue, gingiva, alveolar bone, teeth)
antioxidants
-counteract damaging effects of oxidation
-sources: fruit, veggies, nuts, whole grains, legumes
-include vitamins, minerals and enzymes
research suggests that antioxidants
-influence perio disease and wound healing
-important in downregulation of proinflammatory responses
who is at risk for nutritional deficiencies?
-underdeveloped nations
-infants
-institutionalized elderly
-alcoholism
-fad diets
-eating disorders
-malabsorption disorders (Crohn's, colitis, Celiac)
fat soluble vitamins
-vitamin A (eyes)
-vitamin D (bones, teeth)
-vitamin E (wound healing)
-stored in body
vitamin A
-fat-soluble vitamin needed for epithelial cell differentiation, bone remodelling, cell-mediated immunity and T-helper cell differentiation
-plays a key role in epithelial maintenance
-no significant relationship w/ risk for perio
-found primarily in animal fats & fish oils as retinoids
case report: 20 year old woman with gingival ulcerations, bleeding, swelling and xerostomia
-reported taking 200,000 IU of vit A daily for 6 months
-gingival improvement in 1 week; tissue normal at 2 months
vitamin D
-obtained from diet & synthesized via sun exposure
-helps enhance calcium and phosphate absorption and maintain blood calcium levels
-aids calcification of teeth and osseous tissues
-acts as anti-inflammatory agent
-good sources: egg yolk, liver, oily fish, fortified milk
-promotes differentiation of monocytes to macrophages
what may vitamin D help
-reduce gingival inflammation and BOP
-reduce susceptibility to gingival inflammation
-prevent tooth loss when taken with calcium
vitamin E
-protects cell membranes from oxidative damage
-reduces prostaglandin E2 production in macrophages
-has mitigating effects on gingival inflammation
-supplementation shown to have positive effect on immune response
-good dietary sources: nuts, seeds, wheat germ
water-soluble vitamin deficiencies
-not stored in body in significant amounts (includes vitamin B & C)
-B-complex deficiencies (thiamin, riboflavin, niacin, pyridoxine (b6), biotin, folic acid, cobalamin (b12(
-glossitits, angular cheilitis and may intensify biofilm induced gingivitis
folic acid
-belongs to b-complex group of vitamins
-involved w/ DNA synthesis
-deficiency may reduce ability of gingival tissue to act as barrier to bacteria
-dietary sources: enriched grains, broccoli, asparagus, brussel sprouts, peas, brown rice
calcium
-involved in calcification process
-RDA 1000mg for adults aged 19-50
-plays important role in formation & maintenance. of alveolar bone
-higher daily intake may decrease risk for tooth loss
-dietary sources: milk, yogurt, cheese
magnesium
-found in all cells
-concentrated in mitochondria
-supplementation may improve perio health in individuals aged 40 years and older
vitamin C (abscorbic acid)
-water soluble & cannot be stored in body
-must be obtained through dietary sources
-found in fresh fruit & veggies
-has curative effect on scurvy
-RDA 90mg for men, 75mg for non-pregnant/non-lactating women
vitamin C (ascorbic acid) deficiency
-uncommon in undeveloped countries
-scurvy (systemic disorder caused by severe and prolonged, vitamin C deficiency, oral and systemic changes)
-fresh fruits, vegetables, fortifying diet with vitamin C supplements
what can vitamin C deficiencies cause
-defective formation/maintenance of collagen-osteoblast function, wound healing, bone cell function, blood vessel wall, platelet function
-metabolism of folic acid, iron
-affects RBC production
-increase in bleeding, bruising, poor wound healing
clinical characteristics: ascorbic acid deficiency related gingivitis
-gingiva changes (redness, enlarged, soft, gingival pockets, increased bleeding, surface necrosis)
-systemic symptoms (fatigue due to anemia), dermatitis, purpura (platelet problems)
-histopathology (increased tendency for internal gingival hemorrhage, degeneration of collagen fibers, edema of the CT)
ascorbic acid deficiency related gingivitis etiology
-gingivitis is not caused by the vit c deficiency
-caused by bacterial biofilm
-deficiency aggravates the condition
-in absence of biofilm, the deficiency will not tend to have a profound effect on the tissues
what is the perio therapy for ascorbic acid-deficiency gingivitis
1. diagnosis facilitated by a nutritional assessment
2. consult/referral to physician/dietician regarding blood cell counts and to correct vit C and other deficiency, assess for need for addiction counseling (may request bloodwork)
3. client education: OHI, dietary counseling, smoking cessation
4. removal of local irritants (similar tx plan as biofilm induced gingivitis
5. eval
6. frequent CC intervals
rebound scurvy
-extremely rare condition that can occur w/ abrupt cessation of vic C intake after routinely taking excessive dosages for prolonged period
-can reverse by reinstituting vic C allowance
-high risk for newborns whose mothers had taken heavy doses of vit C during pregnancy
what are some effects of nutritional deficiencies on the perio tissues
-protein deficiencies may affect the host defenses/immune response
-more common in developing countries
-more susceptible to perio infections
