Impression material cause bad taste to patient:
- a- poly sulfide. ***
- b- polyether.
- c- additional silicon.
- d- alginate.
That's correct! The most common impression material that causes a bad taste in patients is a- poly sulfide.
Here's a breakdown of the options and why poly sulfide is the culprit:
- Poly sulfide:
This material has a strong, unpleasant odor and taste that can linger in the mouth for some time. It's often used for crown and bridge impressions due to its accuracy and detail, but the downside is the unpleasant sensory experience for the patient.
- Polyether:
While not as common as poly sulfide, some brands of polyether can have a slightly unpleasant taste. However, it's generally less noticeable and less of a concern for patients compared to poly sulfide.
- Additional silicon:
This is not a specific type of impression material. Silicone-based impression materials are generally considered odorless and tasteless.
- Alginate:
Alginate is another common impression material that is well-tolerated by most patients. It has a bland taste and doesn't linger in the mouth.
Therefore, based on the options presented, poly sulfide is the most likely culprit for causing a bad taste in patients during an impression procedure.
