Tooth erosion
Conditions
Interventions
The clinical study will be a controlled, interventional, randomized, and prospective trial with a double-blind design (including both assessors/examiners and participants) and a split-mouth approach,
and 2) Time in six levels: initial, 7 days, 6 months, 12 months, 18 months, 2 years, and 5 years. The experimental unit will be the patient (n=35).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Clinical Performance: will be evaluated at each return visit using two evaluation methods: modified USPHS and FDI. Both methods present pre-determined categories and scores regarding the functional and aesthetic characteristics of the restorations. | — |
Secondary
| Measure | Time frame |
|---|---|
| Participants' degree of sensitivity: It will be measured and reported by the patient using a Visual Analogue Scale (VAS) from 0 to 10, with 0 - no pain and 10 - intolerable pain.;Analysis of participants' quality of life: For this analysis, the OHIP-14 questionnaire will be used with the objective of evaluating the impact of non-carious cervical lesions on functional limitation, physical pain, psychological discomfort, physical disability, psychological disability and social disability of the participants. Each participant must answer 14 questions using a Likert scale, from zero to four, with 0 corresponding to never, 1 to rarely, 2 to sometimes, 3 to frequently and 4 to always.;Classification of participants' risk of Erosive Dental Wear (DDE): It will be assessed using the BEWE Index (Basic Erosive Wear Examination). In this method, each tooth surface will be classified according to the score from 0 to 3 (0 - no signs of erosive wear, 1 - initial loss of surface texture, 2 - distinct defect, with less than 50% surface involvement, and 3 - involvement greater than 50% of the tooth structure). The sum of the highest scores observed in each dental sextant of the patient determines their risk level as zero (0-2), low (3-8), medium (9-13) and high (14-18).;Degree of dentin sclerosis: The sclerosis of each lesion will be measured using an scale in which dentin is classified according to its optical characteristics by the evaluator in a grade from 1 to 4. | — |
