Brief summary

This protocol is for a clinical trial to evaluate the reliability of the bite fork as a diagnostic instrument in subjects with pulpal necrosis and apical periodontitis.

Detailed description

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).
