Study Notes
Effects of Ionizing Radiation
- The cumulative effect refers to accumulated unrepaired damage from ionizing radiation over time.
- Somatic effect: injury occurring in the person exposed to ionizing radiation, not involving reproductive tissue.
- Genetic effect: exposure of reproductive tissues resulting in injury to future generations.
Oral Manifestations of Diseases
- Spina bifida: a neural tube defect with no associated oral manifestations.
- Anorexia bulimia: causes multiple oral problems, including chronic sore throat, parotid gland swelling, and dental issues.
- Sickle cell disease: causes multiple oral problems, including trabeculations, delayed tooth eruption, and pain in teeth and mandible.
- Down syndrome: a craniofacial syndrome with multiple oral manifestations.
Experimental Design
- Independent variable: the variable believed to influence the outcome variable.
- Dependent variable (outcome variable of interest): the variable being measured or observed.
- Stratified sampling: a method of randomly selecting subjects from two or more strata to increase the likelihood of a focused study.
- Systematic sampling: selecting every "nth" person in a randomly ordered list to increase the likelihood of random selection of subjects.
