Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This clinical trial consists of two parts. We will first use the bite fork in normal volunteers to evaluate its test-retest and inter-rater reliability. We will then use the bite fork in subjects with differing endodontic diagnoses and compare these results with the standard clinical diagnostic test (percussion).
