Failed tooth restorations
Conditions
Interventions
Fourteen-six patients will have 2 teeth (split-mouth) restored each one with a different restoring system: 1) restoring with conventional composite resin with incremental technique
2) restoring with bulk-fill resins in bulk-increments of up to 4 mm covered with 1 mm of conventional resin. All the procedures will be performed in a single appointment by only one trained and specia

Eligibility
Age
18 Years to 70 Years
Inclusion criteria
Inclusion criteria: It was compulsory for the patients to present a pair of class I or II failing restorations (amalgam/composite resin) with cusps partially involved and/or carious lesions on occlusal and/or proximal surfaces. The teeth needed necessarily to be vital as well as the participants were required to be free of edentulous spaces, important occlusal interferences and parafunctional occlusion. The patients were required to be between 18 and 70 years old and to not participate of another clinical study.
Exclusion criteria
Exclusion criteria: It was excluded from the sample those patients with allergy to the materials, cracked teeth, periodontal disease, using chlorexidine at the baseline, tooth sensitivity, antagonist teeth, presenting porcelain restoration as well as a indirect restoration planned to be done. The patients disabled to attend the re-calls as well that present any general health problem existent were not included in the sample.

| Expected outcome 1: Satisfactory clinical performance of restorations using low-contraction (bulk-fill) resin composites in posterior teeth, being determined by means of USPHS (Scores Alfa and Bravo) and FDI (Scores 1 and 2). Detection of other scores following these evaluations would mean the failure of these restorations. ;Found outcome 1: The long-term evaluation of the clinical performance of the bulk-fill restorations in posterior teeth showed acceptable results in both USPHS (Only scores Alfa and Bravo were detected) and FDI (Only scores 1 and 2 were detected) evaluation methods. | — |
