T/F: Well-established materials have little deficiencies, tolerated deficiencies, or both.
True
When trying new materials, there are three groups of people: ____, _____, or _____.
early adopters
the pack
waiting for tried/tested materials
T/F: Original dental materials were developed by applying available materials to dental restorations.
True, often industrial materials
T/F: Natural human biomaterials are developed through normal human growth and development
True
_____ seek to mimic biology and nature to develop biomaterials.
biomimetics
T/F: Biomimetics are very successful in producing practical dental biomaterials for direct clinical use.
False
Nanostructured ceramics for dental implants include ____ coatings on Co-Cr and Ti alloys or enhancement of ____ coatings for adhesion/durability.
diamond
hydroxyapatite
T/F: Self-replacing dental materials will induce the body to produce a body material that is no longer producing (i.e: enamel).
True
Case series, cross-sectional studies, cohorts, and case-control studies are examples of ____ studies.
observational
T/F: Cohort studies are prospective.
True, (PRO-CO)
T/F: Case-control studies are retrospective.
True
What is the difference between a cohort study and an experimental study?
cohort: assignment is not controlled
experiment: assignment is controllled
