Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Patients must be at least 18 years old, in good general and oral health; Dental elements of the study should have a premolar or molar with satisfactory endodontic treatment, loss of at least one proximal wall, being in occlusion and having adjacent teeth, have a coronary structure remaining from the buccal or palatal/lingual walls with at least one cavity wall with a thickness of <2mm
Exclusion criteria
Exclusion criteria: Patients with poor oral hygiene will be excluded from the study; smokers; pregnant women; teeth that have color changes due to intrinsic factors (dentinogenesis and amelogenesis imperfecta, fluorosis, tetracycline); periodontal disease; severe parafunctional habits and active clasps of removable partial dentures in the tooth included in the study
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The expected preliminary stage includes evaluating the occurrence of retention failures and fractures in polyethylene fiber restorations in comparison to cusp lowering, estimating that the longevity of the restoration and survival rate of the restored teeth is similar in both groups, with few failures and no statistically significant differences between groups. | — |
Secondary
| Measure | Time frame |
|---|---|
| The expected secondary results include evaluating the appearance of a secondary carious lesion, evaluating the integrity and marginal discoloration, in addition to radiographic analysis of the tooth. Radiographic analysis of the tooth must show adequate adaptation of the restoration and no evidence of tooth fracture or root resorption, so that there is no statistically significant difference between the groups. | — |
