  2. 2. Influence of systemic diseases on periodontum Prof Dr .Eman Abd El- Sattar TellaFaculty of Dentistry Umm Al Qurra University Makka,SA
  3. 3. I. Nutritional disorders
  4. 4. There are no nutritional diffeciences that by themselves can cause gigivitis or periodontitis but it can affect the condition of the priodontium & aggrevate the injurious effect of local factors.Physical character of the diet :in experimental animals it was found that:1- Soft diet ( nutritionally adequate )  plaque and calculus formation.2- Hard fibrous food  surface cleaning action and stimulation  less plaque and calculus even if nutritionally inadequate .
  5. 5. In humans effect of nutrition ort oral M.O.: Dietry intake, influence the oral, bacteria as it form the source of nutrition for bacteria . So, it influence: Relative distribution of types of organisms. Metabilic activity of the organisms. Pathogenicity of organisms.
  6. 6. I. VitaminDeficiency
  7. 7. A ) fat soluble Vit.(1) Vit. A Diffeciency Function: maintain the health of epithelial cells of the skin and m.m. responsible for re-epitheliazation as epithelial tissues provide a protective barrier against invading micro- organismsVitamin A diffeciency result in: dermatologic , mucosal and accular manifestations . degenerative changes in epithelial tissues resulting in keratinizing metaplasia .
  8. 8. (2) Vit. D “calciferol” Function: absorption of calcium from GIT . maintainer of calcium phosphorus balanceVitamin D diffeciency result in: Inexperimaental animals there will be :1. Osteoprosis of alveolar bone .2. Sever alveolar bone resorption  Proliferation of fibroblast that replace the bone and marrow  New bone formation around the remnant unresobed bony trabiculae .3. Radiographically :• absence of lamina dura .• decrease density of supporting bone• loss of trabeculae.
  9. 9. (2) Vit. D "calciferol” Function: absorption of calcium from GIT . maintainer of calcium phosphorus balance
  10. 10. (2) Vit. E Function: anticxiddant to limit the free radical reaction . protect cells from peroxidation .Effect of vit. E diffeciency no relationship demonstrated between vit.E and oral disease in humans .
  11. 11. B) Water soluble Vitamins(1 ) vit, B complex: Thiamin. Riboflavin. Niacin. Pyridoxine (B6). Biotin. Folic acid. Cobalamin (B12).
  12. 12. oral diseases rarely accure due to diffeciency in one component but diffeciency is generally multiple Thamin Riboflwin Niacin Folic acid Diffeciency Diffeciency Diffeciency Diffeciency1- Beriberi: 1) Glossitis 1) Pellegra : • Macrocytic anemia• paralysis. • Magenta discoloration •Dermatitis. with megaloplastic• C.V. symptoms. and atrophy of tongue •GIT disturb. erythropiosis• Edema . papillae. •Mental disturb.• Loss of appetite • In mild cases there is •Glossitis. • Diarhea and GIT patshy atrophy with •Gingivitis. malabsorption2) orally : engorged fungi form •Stomatitis• hypersensitwity of papillae. • In luimans : oral mucosa • In severe cases the a. generalized• Minute viscles on dorsum tongue is flat, dry stomatitis• The B. mucosa, and fissured. b. ulcerated glossitis under the tongue or c. cheihtis on the palate. 2) Seborrheic• Errosion of the oral • Dermatits mucosa 3) Dangular cbeilitis • Which is inflammation at the lip commisures.

  14. 14. Ariboflavinosis, angular In folate deficiency angularcheilitis, erythema, and cheilitis may be marked.atrophy of tongue papillae.
  15. 15. (2) Vit. C Vit. C deficiency lead to :Scurvy which characterized by : Haemorrhage lesion into the ms. Of extremities, joints. Petechial haemorrhage. Increase susceptibility to infection around hair follicle and delayed wound healing . Bleeding and swollen gingiva. Loosening of teeth
  16. 16. Relationship between vit. C & P. diseases : Decrease vit. C deficiency influence the metabolism of collagen in the P. tissues decrease ability of the tissues to regenerate and repair themselves. Decrease vit. C deficiency interfere with bone formation due to failure of osteoblasts to form osteod and decreased calcification o the osteod tissues deficiency loss of the periodontal bone . Increase vit. C deficiency enhance the chemotactic and migratory action of leukocytes without affecting their phagocyte activity. Optimal level of vit. C is required to maintain the integrity of periodontal microvasculature and wound healing.

  24. 24.  Non insulin dependent diabetes.  Caused by peripheral resistance to insulin impaired insulin secretion and increased glucose production by theType II liver.  Preceded by obesity  Coma and ketosis not common  Adult onset and treatment by diet control or hypoglycemic agents
  25. 25.  Gestational diabetes : diabetes associated with pregnancy in 2% - 5% of women but it disappear after delivery . Diabetes associated with diseases involve pancreas and cause destruction of insulin or pancreateactomy .
  26. 26.  Xerostomia . Gingiva: inflamed. enlargement either localized or generalized. sessile or peduncualted gingival p lips. Gingival color is bright red  dark red . Alveolar bone destruction, deep periodontal pockets and looseing of the teeth. Increased susceptibility to infection due to diffceicncy in Polymorophnuclear leukocytes  impaired chemotactic and phagocytosis.
  27. 27.  Frequent abscess formation due to : high glucose level which serve as bacterial substrate. impaired chemotactic and phagocytosis of neutrophils. Impaired wound healing due to and collagenitic activity and decrease synthesis of collagen which is important for- wound healing . Alterations in the bacterial pathogenes and oral microbial flora this is clue to higher glucose content of gingival fluid and blood which in turn alter the environment of microflora in ducing qualitivate changes in bacteria that account for severity of periodontal disease .
  28. 28. 2- Hyper parthyrodismIt will be lead to: generalized demineralization of the skeleton . increase osteoclasits with proliferation of C.T. in the enlarged marrow spaces diffeciency bone cyst and giant tumors ( osteitis fibrosa cystica )oral changes include Malocclusion and tooth mobility. Widening of P.L. space. Absence of lamina dura. Cyst like space in the jaws, diffeciency filled with fibrous tissues and haemosedrin laden macrophages and giant cells ( brown tumors ).
