The purpose of this study is to assess tooth health by using a pulse oximeter which measures the blood flow within the tooth. This method is not currently being used in dentistry. We hypothesize that if we can measure both sensation and blood flow in a tooth, we will be able to better determine if the tooth is "alive or dead". In the future, this method may help determine which teeth are diseased and require dental treatments.
The vitality of the pulp is determined according to the health of the vascular supply not the sensory fibers. Conventional subjective tooth assessments (percussion, palpation, cold, and electrical pulp testing) and objective pulpal blood flow measurements will be used for teeth that are planned for extraction and also up to 2-5 additional teeth in each participant. The correlation between a single combined score from collective conventional subjective tooth assessments and the objective pulse oximetry reading for selected teeth will be used to evaluate if pulse oximeter measurements are a reliable marker for patient's reported symptoms.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Oximetry testing of healthy teeth and those requiring removal | To assess the ability of pulse oximeter to assess the presence of pulse in teeth and to correlate pulse oximeter readings with conventional pulp testing measures including cold test, electrical pulp test, percussion and palpation testings, pulse oximeter will be used with a special holding frame, for 15-30 seconds. Note: the reading will not affect clinical practice; it is simply to gather data to see if pulse oximetry can facilitate diagnostic practices in the future |

| Pulse Oximetry | Device | Pulse Oximeter is being applied with a special holding tool to test the oximeter for its ability to measure pulpal blood flow, but no effect of the oximeter is being measured. Thus, to that degree the use is observational rather than interventional. |

| Subjective Tooth Assessment: Number of Teeth With Normal and Abnormal Pulp | Conventional subjective tooth assessments (percussion, palpation, cold, and electrical pulp testing) will be used for teeth that are planned for extraction and also upto 2-5 additional teeth in each participant. Pulp status is determined as "normal" or "abnormal" according to the classification system from the American Academy of Endodontics. | Single visit, less than one hour testing |

| Objective Tooth Assessment: Pulse Oximetry Reading for Selected Teeth | Objective plural blood flow measurements will be used for teeth that are planned for extraction and also up to 2-5 additional teeth in each participant. Average objective plural blood flow was determined by pulse oximetry-reading for selected teeth (measured as SpO2). | Single visit, less than one hour testing |
