Q

How are new materials screened for biocompatibility?

A

By comparing the host response to a reference/control material in a standard test

17
Q

a material that elicits a reproducible, quantifiable, host response in a standard test

A

Reference/Control Material

18
Q

Elicits a minimal response

A

Negative control

19
Q

Elicits an adverse host response

A

Positive control

20
Q

Ceramics biocompatibility?

A

Bioinert

21
Q

CaOH and MTA Biocompatibility

A

Bioactive

22
Q

Calcium phosphates biocomp?

A

Bioactive

23
Q

High purity alumina biocomp?

A

Bioinert

24
Q

How neutrophils find foreign material

A

chemotaxis

25
Q

Chemotactic substances for neutrophils

A

Opsonin, pH, electrochemical

26
Q

Process of phagocytosis

A

Chemotaxis –> invagination of cell –> secondary lysosome formed in cell –> primary and secondary lysosomes form and attack the antigenic substance –> absorbed, degraded, or released
