Interventions

This is a randomized, controlled, double-blind clinical trial with 42 participants with two non-carious cervical lesions side by side who were randomly distributed into two groups with allocation defi
the initial color of the teeth was assessed with a digital spectrophotometer before the intervention
dental whitening was performed in two office sessions with new measurements taken after each session and in subsequent follow-ups of 7, 14 and 30 days

Inclusion criteria

Inclusion criteria: Good general health; good oral hygiene; present at least 20 teeth under occlusion; at least two non-carious cervical lesions comparable in size, shape and dimensions; non-retentive; deeper than half a millimeter; involve both the enamel and dentin of vital teeth; the cavosurface margin cannot involve more than 50% of the enamel; never having undergone dental whitening

Exclusion criteria

Exclusion criteria: Extremely poor oral hygiene; wearing orthodontic appliances; severe or chronic periodontitis; heavy bruxism habits; known allergy to resin-based materials or any other material used in this study; pregnant or lactating women; chronic use of anti-inflammatory, analgesic and psychotropic drugs; patients who have already undergone dental whitening

Design outcomes

Primary

MeasureTime frame
To evaluate the color performance of a monochromatic composite resin versus a traditional composite resin using a digital spectrophotometer in non-carious cervical lesions before and after dental bleaching. Interim analyses of immediate data and at 6, 12, 24, 36 and 60 months will be performed

Secondary

MeasureTime frame
Evaluate the aesthetic properties; functional properties and biological properties using the World Dental Federation clinical criteria on the performance of a monochromatic composite versus a traditional composite in non-carious cervical lesions. Interim data analyzes will be performed immediate and 6, 12, 24, 36 and 60 months
