QUIZ I Intro to Oral Biology Flashcards
what is the craniofacial complex?
head, face, and neck
in order to properly diagnose, prognosticate, treat, and evaluate dental diseases and disorders, we must fully understand what?
how normal tissues develop and function
what makes up the dentition?
- teeth
- enamel
- dentin
- cementum
- bone
- periodontal ligament
describe teeth
- occupy 20% surface area in the oral cavity
- masticatory force 500-700 newtons/ 110-160 lbs of force
- mastication, speech, esthetics, defense, bone health
describe enamel
- 96% mineral
- non-vital
- brittle
- ameloblasts
describe dentin
- ~70% mineral
- elastic
- permeable
- vital
- odontoblasts
describe cementum
- 50% mineral
- thin
- vital
- attachment site
describe bone
- 50% mineral
- support
- remodels continually
describe the periodontal ligament
- hammock
- fibrous
what 3 features form the periodontium?
cementum, bone, and periodontal ligament
what is the clinical crown?
the visible portion of the crown that is not covered by gingival tissues
what is the anatomic crown?
the entire part of the crown covered in enamel (it is usually larger than the clinical crown in a healthy mouth)
describe finding disease genes
nucleus → chromosome → band → gene → mutation
describe approaches to identifying disease susceptibility genes
- linkage analysis
- studies families with more than one affected individual
- candidate gene analysis (association study)
- compares people with the disease to people with the disorder
- case-control
what are 2 forms of genetic variation?
mutation and polymorphism
