Q

How are K-files identified

A

Color coated to identify size, mm length, diameter is the size of the file on the working end

17
Q

Describe some common irrigation materials.

A

Sodium hyperchlorite: Breaks down & remove organic material
Chlorhexidine: Disinfects, flushes out debris
Saline
RC prep: EDTA, helps break down the inorganic material

18
Q

What is ZOE?

A

Zinc oxide & Eugenol-based sealant, to prevent bacteria, non-irritating antimicrobial agent. Mix thoroughly, dip gutta-percha, place in the canal

19
Q

What is Gutta-percha

A

Most popular core material**, non-irritating, highly condensable, helps remove voids in the sealer to provide a better seal at the apex. Supplied in different sizes & lengths, made from rubber.

20
Q

Describe pluggers

A

Have blunted tips, used to compact the gutta-percha

21
Q

Describe spreaders

A

Have sharp tip, used for laterally compacting gutta-percha

22
Q

What is Restorative Dentistry?

A

To protect the tooth after endodontic therapy, to restore the form and function of the damaged tooth* applied to dry surface

A

Premolars and molars are positioned anterior to the normal relationship (prognathism)

30
Q

What is a Wry bite?

A

Different length of the two jaws, genetically transmitted.

31
Q

What does Guided Tissue Regeneration do?
