Dentin sensitivity
Conditions
Interventions
20 class I (occlusal) and class II composite resin restorations in molars and premolars will be performed in 74 patients with a universal adhesive and a resin composite under absolute isolation. Each
(B) adhesive restoration using the etch and rinse (ER) technique (control)
(C) adhesive restoration using the self-etching technique with previous application of Gluma desensitizing agent (SE / GL)
(D) adhesive restoration using the etch and rinse technique with the application of Gluma desensitizing agent (ER / GL)

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected to find postoperative sensitivity assesed by pain scales: Pain Visual Analog Scale (VAS) and Numeric Rating Scale for Pain (NRS), showing mild, moderate or severe pain scores. | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to find, based on assessments of 6, 12 and 18 months, using the FDI (World Dental Federation) and the USPHS (United States Public Health Service) changes in discoloration, roughness, marginal desadaptation, fracture and secondary caries in composite resin restorations, showing alpha, beta or charlie scores. | — |
