Answer:
search quality, credence quality.
Explanation:
The search quality can be defined as the quality of those products that can be evaluated fully before purchasing. Search quality help to analyze the product and to make the decision, whether to buy the product or which one to buy. For example, assessing a refrigerator before buying.
Credence quality, on the other hand, is the quality that can not be evaluated even after purchasing the product. In this form of quality, customers are unable to assess the quality of a product even when they have purchased it and consumed it. 
<u>In the given case, Wendy was able to evaluate the product quality of the braces (search quality) but unable to evaluate the service of her orthodontist even after receiving the service because she had faith in her orthodontist (credence quality)</u>.
Thus the correct answers are search and credence quality.
