Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Individuals of both sexes. Minimum age of 18 years. Individuals in good general health who have at least one vital posterior tooth, whose vitality can be confirmed by means of a cold stimulation test, in need of restoration due to carious lesions or replacement of an inadequate previous restoration due to aesthetic reasons, fracture or secondary caries. The tooth of interest must necessarily have an opposing tooth in occlusion. The cavities must present occlusal involvement (class I and II) and be at least 4 mm deep, measured at the time of screening using bitewing radiographs and a millimeter ruler and at the time of intervention by measuring the cavity after preparation
Exclusion criteria
Exclusion criteria: Pregnant women; lactating women; those with uncontrolled systemic diseases or who report hypersensitivity to the components of the materials used in the intervention; individuals who have severe periodontitis; non-carious cervical lesions; poor oral hygiene; conditions that may alter the perception of pain, such as neuropathies, chronic pain disorders, severe bruxism and continuous use of medications such as analgesics and anti-inflammatories
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It's expected to find a difference of at least 30% of postoperative sensitivity occurrence, that will be assessed through pain scales. Participants will be asked to record the occurrence and intensity of pain for each restored tooth at intervals of 24 hours, 48 ??hours, 7 days and 6 months after the procedure, using two pain scales. The Numerical Rating Scale (NRS) consists of 5 points between 0 and 4, where 0 means no sensitivity, 1 means mild, 2 means moderate, 3 means considerable and 4 means severe. The Visual Analogue Scale (VAS) consists of a 10 cm horizontal line, where the 0 cm end indicates no sensitivity and the 10 cm end indicates severe pain. The patient should mark their pain intensity with a vertical line, and the distance in millimeters will be measured with the aid of a millimeter ruler and considered for statistical purposes. The occurrence of sensitivity will be considered as any value above 0 for both scales, and evaluated whether it occurs spontaneously or in response to stimuli, which must be specified and recorded, as well as the date of the occurrence of pain | — |
Secondary
| Measure | Time frame |
|---|---|
| It's expected to find better clinical performance of intervention group, that will be assessed 6 months after the procedures, through tactile and visual clinical examination, using clinical mirror and probe under artificial lighting, by two independent evaluators who are blind to the group allocation. The assessment will follow the criteria defined by modified USPHS (United States Public Health Service) for marginal adaptation, anatomical form, marginal discoloration and secondary caries, and modified FDI (World Dental Federation) for aesthetic, biological and functional characteristics, as well as the need for repair or replacement of restorations | — |
