Participant Flow

The study had a pre-intervention phase, 108 clinicians (HS trained, consented, and met eligibility criterion) and 1500 patients enrolled. 85 clinicians met the enrollment threshold and were randomized.1500 patients were in the post-intervention phase.The pre- and post patients were not the same so the number analyzed for each group varies.

Measure	No Device Practitioners The practitioners will not receive any additional training.	Spectra Device Practitioners The practitioners in the Spectra Device Arm will be trained to the device according to the manufacturers' usual care for training. The training will consist of viewing the manufacturer's instructions for the device. Training will also consist of practitioners familiarizing themselves with the device through unsupervised clinical use with patients. Spectra Device: Spectra Caries detection device is used for study data collection recording the results of the dental examination and recording results of dental treatment.	DIAGNOdent Device Practitioners The practitioners in the DIAGNOdent Device Arm will be trained to the device according to the manufacturers' usual care for training. The training will consist of viewing the manufacturer's instructions for the device.

PRIMARY outcome

Timeframe: Pre-intervention and post-intervention (one day visit)

Population: Only the patients who received invasive treatment were analyzed for extension into dentin.Not all columns add up to the total N due to missing values.

There was one lesion/patient.

Clinicians' likelihood of treating surgical lesions depicted with brown verses black, smooth verses rough, shiny verses matte, in patients with high verses low caries risk, by post-intervention phases. The outcome measure will be to see what cues were used or treatment decisions in the post-intervention phase. Please note that more than one cue could be chosen, so values may add up to more than 100 percent. Participants in the no device group did not receive a device reading cue.
