Gingival Anatomy

The goal of this study is to optimize the matching between Optical Coherence Tomography (OCT) imaging and the true anatomy of the tooth. It also non-invasively tests how reliable the OCT scanner can access tissue integrity, measure depth, and detect texture features. These features will be important to plan for treatment. The specific aims of this study are: 1. to correct for distortion caused by internal refractive indices to restore true tooth anatomy 2. to test the feasibility and usability of the full-motion OCT scanner in volunteers. Participants may be in one of the following groups 1. Some teeth that are extracted according standard treatment plan will be scanned with OCT. 2. Some participants will have their teeth and gum in the mouths scanned by OCT
