Question

Erratic and inconsistent results from electric pulp testing may be caused by (a) saliva on the tooth; (b) secondary dentin obliterating the pulp chamber; (c) multiple canals presenting various stages of pulp pathosis.

A. (a) only
B. (a) and (b)
C. (a) and (c)
D. (b) only
E. (b) and (c)
F. (c) only
G. All of the above

Answer 1

Erratic and inconsistent results from electric pulp testing can be caused by saliva on the tooth, secondary dentin obliterating the pulp chamber, and multiple canals presenting various stages of pulp pathosis.

Step-by-step explanation:

Erratic and Inconsistent Results from Electric Pulp Testing

Erratic and inconsistent results from electric pulp testing can be caused by several factors:

1. Saliva on the tooth: Saliva can interfere with the electrical current used in electric pulp testing, leading to inaccurate results.
2. Secondary dentin obliterating the pulp chamber: Secondary dentin is a protective layer that forms inside the pulp chamber as a response to injury or irritation. If the pulp chamber becomes obliterated by secondary dentin, the electrical current may not reach the pulp accurately.
3. Multiple canals presenting various stages of pulp pathosis: The presence of multiple canals and different stages of pulp pathosis can complicate electric pulp testing, making the results inconsistent.

In conclusion, all of the above factors - (a) saliva on the tooth, (b) secondary dentin obliterating the pulp chamber, and (c) multiple canals presenting various stages of pulp pathosis - can contribute to erratic and inconsistent results from electric pulp testing.
