The different types of anemia are important to know. Make a study-table comparing iron-deficiency anemia and megaloblastic (pernicious) anemia. Include: typical physical symptoms, oral changes, cause of, treatment for, examples of dietary suggestions/interventions.
*Iron-Deficiency Anemia- caused by a deficiency of dietary iron or by excessive bleeding. Likely to occur during infancy or pregnancy. Lethargy and fatigue in addition to glossitis, apthous ulcers, and xerostomia associated with iron-deficiency anemia can lead to changes in appetite and food intake. Clinical symptoms in the oral cavity include gingival and mucosal pallor, angular cheilosis, and atrophic glossitis. Iron supplements help symptoms to resolve in 48 hours, and filiform papillae regenerate in 3 to 4 weeks. *Megaloblastic (Pernicious) Anemia occurs when Vitamin B12 is deficient in the diet, absorption is inadequate, or requirements are incrust. Vitamin B12 deficiency is most common among vegans who consume no animal products. Symptoms include: angular cheilosis, recurrent pathos ulcers, erythematous mucositis, and pale or yellowish oral mucosa. Patients may also complain of a painful, sore, burning tongue with signs of atrophic glossitis associated with a beefy red color. Replacement therapy with vitamin B12 supplements or injections relieves symptoms within 36 to 48 hours with evidence of regeneration of tongue papillae within 4 to 7 days, and the tongue may be normal in 3 to 4 weeks. *Another type of megablastic anemia, caused by folic acid deficiency is frequently associated with poor diets or medications that interfere with folate absorption or metabolism. Oral manifestations are similar to symptoms present in pernicious anemia: glossitis, atrophy of the papillae, ulcerations, and glossodynia (pain of the tongue). Folate replacement is necessary because diet alone is inadequate to replace lost stores.
T/F Patients who use excessive alcohol or caffeine, or smoke cigarettes, are at risk of calcium loss.

What is hydrogenation?
A commercial process in which vegetable oil is converted to a solid margarine or shortening by adding hydrogen to the oil.
Describe a full liquid diet.
A full liquid diet provides food in a liquid form for patients who are unable to chew. It should consist of high-protein, high-kilocalorie fluids and semi-solid foods to promote optimal healing. A full liquid diet is used only temporarily because nutrient and caloric value is usually inadequate.
Describe a mechanically altered diet.
A mechanically altered diet is a regular diet altered in consistency and texture for ease in mastication when chewing may be compromised. The diet includes soft, ripened, chopped, ground, mashed, and pureed foods. Foods are generally moist. This diet is recommended for 3-7 days until the patient can tolerate regular foods.
Name factors that influence the properties of plaque biofilm and saliva.

Identify some conditions associated with neutropenia. Should dental hygiene treatment be performed when a patient is experiencing an episode of neutropenia?
Neutropenia results from dysfunctional bone marrow: cancer (leukemia), drugs (chemotherapeutic agents or antibiotics), radiation therapy, autoimmune disease (rheumatoid arthritis or systemic lupus erythematosus), bone marrow transplant, nutritional deficiencies (severe vitamin B12 or folate deficiency), or certain bacterial or viral infections (HIV, malaria, tuberculosis, or Epstein-Barr virus). When neutropenia is present, invasive dental treatment is usually contraindicated until WBC counts increase. If treatment is indicated, a consultation with the healthcare provider is necessary to determine if antibiotic prophylaxis is needed.
What is palatability?
