Eligibility
Inclusion criteria
Inclusion criteria: older than 18 years; both genders; needed for Class II restorations due to the presence of carious lesions and / or due to replacement of preexisting restorations with caries recurrence, loss or fracture of restorations; presence of at least three vital dental elements to be restored by each participant whose opposing teeth are present; good general health; acceptable level of oral hygiene; presence of at least 20 teeth under occlusion.
Exclusion criteria
Exclusion criteria: high risk of caries and / or periodontal disease; holders of removable or orthodontic appliances; patients with bruxism and / or xerostomia; cavities which, after preparation, do not have a minimum depth of 4 mm in the proximal box; pregnant or breastfeeding.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The performance of composite resin restorations at the baseline, 6 months, 12 months and 18 months will be verified through the analysis of the variables proposed by the FDI, comparing the percentages of each score obtained in each time evaluated. The main outcome variable is fracture and retention, which will be evaluated according to scores that include: clinically very good (retained restoration, no fracture / cracks), clinically good (Small fracture line), clinically sufficient / satisfactory (extensive fracture line (Fracture fractures, which cause damage to the marginal quality, fracture volume with or without partial loss - less than half of the restoration) and clinically poor (loss of restoration - partial Or complete). | — |
Secondary
| Measure | Time frame |
|---|---|
| The performance of composite resin restorations at the baseline, 6 months, 12 months and 18 months will be verified through the analysis of the variables proposed by the FDI, comparing the percentages of each score obtained in each time evaluated. The secondary outcomes will be: marginal discolouration, marginal adaptation, postoperative sensitivity and dental vitality and recurrence of caries. The marginal discoloration will be evaluated according to scores that comprise: clinically very good (no marginal discolouration); Clinically good (small marginal discoloration, easily removable with polishing); Clinically sufficient / satisfactory (moderate marginal discolouration, not aesthetically acceptable); Clinically unsatisfactory (pronounced marginal discoloration, necessary intervention for improvement); Clinically poor (deep marginal discolouration not accessible for intervention). The marginal adaptation will be evaluated according to scores that comprise: Clinically very good (harmonious contour, without cracks, without discoloration); Clinically good (small marginal fractures removable by polishing); Clinically sufficient / satisfactory (slits not removable by polishing, minor marginal fractures); Clinically unsatisfactory (cracks or dentin / exposed base, fractures of negative margins, large irregularities, necessary repair); Clinically poor (complete or partial restoration is lost but in situ, generalized major crevices or irregularities). The postoperative sensitivity and dental vitality will be evaluated according to scores that comprise: Clinically very good (at least one sensitivity); Clinically good (low sensitivity for a limited period of time); Clinically sufficient / satisfactory (moderate sensitivity, poor / delayed sensitivity, no patient complaint, no treatment required); Clinically unsatisfactory (severe hypersensitivity, delayed with small symptoms, negative sensitivity, necessary intervention but no substitution); Clinically bad (intense, pulpiti | — |
