The overall objective was to evaluate the monitoring of tooth wear using the intraoral scanner. Forty-six participants were selected according to the established inclusion and exclusion criteria. Monitoring of tooth wear, evaluation of possible aetiological factors, as well as patient satisfaction with the use of the intraoral scanner were carried out.

The overall objective was to evaluate the monitoring of tooth wear using the intraoral scanner. The specific objectives were (1) to determine whether the intraoral scanner is capable of detecting tooth wear superior to traditional visual indices, (2) to identify whether any aetiological factors may be associated with tooth tissue loss, (3) to establish a degree of patient satisfaction with the intraoral scanner as a diagnostic tool. Forty-six participants were selected according to the established inclusion and exclusion criteria. The protocol was accepted by the Regional Ethics Committee of the Community of Madrid. Digitisation of the dental arches was recorded at 3 types of evaluation: 0, 6 months and 12 months. The recording of possible etiologic factors was carried out at the three established evaluation times. The evaluation of satisfaction was recorded at the third evaluation time.
