Dental caries, dentin sensitivity, dental restoration failure, dental restoration wear
Conditions
Interventions

Eligibility
Inclusion criteria
Inclusion criteria: Participants must be healthy; be at least sixteen posterior teeth in occlusion; minimum age of 18 years; have at least two caries or defective restorations in need of replacement in posterior teeth (cavities adjacent to the restoration, fractured restorative material or patient choice of aesthetics); the teeth to be restored should be in occlusion with the antagonist and respond positively to pulp vitality test performed with the application of cold (Roeko Endo-Frost, Coltène / Whaledent, Langenau, Germany, the cavities to be restored must have a minimum depth 3 mm (previously verified by bitewing radiography exam and millimeter probe)
Exclusion criteria
Exclusion criteria: We excluded participants with poor oral hygien; with periodontal disease; endodontic treatment; with extensive prostheses (fixed or removable) or orthodontic treatment; with known allergy to resin-based materials or any other material used in this study; patients with chronic use of anti-inflammatories, analgesics and psychotropic drugs; pregnant or breastfeeding women.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected outcome: The number of patients reporting pain spontaneous for 7 days after the procedure, through self-report. This number will be transformed into percentage of patients with pain and is called absolute risk of tooth sensitivity. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcome: The intensity of tooth sensitivity will be assessed using the numeric 5-point scale (NRS 0-4) and the visual analogue scale (VAS 0-10 and 0-100) and will be presented as means and standard deviations.;Expected outcome: The secondary clinical endpoints were restoration fracture/loss of retention, marginal caries, marginal staining, marginal adaptation, surface texture and color match. We ranked these variables into the following scores: clinically very good; clinically good; clinically sufficient/satisfactory; clinically unsatisfactory but can be repaired and clinically poor which need replacement. For marginal adaptation and marginal staining, we employed the semi-quantitative SQUACE criterion, proposed by Hickel and others. The results of these evaluation criteria are obtained over time. | — |
