Design outcomes

Primary

Measure	Time frame
To evaluate the difference in satisfaction and aesthetic self-perception of the smile, measured by the patient using the Numerical Rating Scale (NRS) and the Oral Aesthetic Subjective Impact Scale (OASIS) Questionnaire, comparing the moments before and immediately after the removal of the composite resin veneers;To evaluate the variation in clinical parameters of the maxillary anterior teeth, through intraoral examination, comparing the moments before and immediately after the removal of the composite resin veneers. Clinical parameters include: bacterial plaque index, gingival inflammation, color evaluation (of the initial veneer and the natural tooth), occlusal evaluation (contacts, overjet, canine guidance or group function, and anterior guidance), dental form evaluation (clinical crown length and volume), and marginal integrity (presence or absence of secondary caries and discoloration of the tooth/restoration interface)	—
