This is a single-center, two-arm, non-inferiority randomized clinical trial with blinded outcome assessment. The study will include 112 endodontically treated posterior teeth, evenly distributed betwe
however, due to the nature of the procedures, operators and participants will not be blinded. In the experimental group, endocrowns fabricated with composite resin will be performed. After removing un

Design outcomes

Primary

MeasureTime frame
Primary outcomes: the success and survival of endocrown-type restorations in semi-direct composite resin versus direct restoration in composite resin retained by fiberglass pins, the evaluations will be in accordance with the criteria proposed by the International Dental Federation (FDI), which include aesthetic, functional and biological properties

Secondary

MeasureTime frame
Secondary outcome - Estimation of the volume of the remainder and assessment of the wear of the restorations. Intraoral scans will be carried out pre-(after removal of decayed tissue/prosthetic preparation) and post-rehabilitative treatments to assess the volume of the remaining dental structure and carry out wear assessments of the restorations. Data analysis will determine the volume of restorations, providing insights into wear levels throughout follow-ups. The intraoral clinical examination of wear will be carried out pre-treatment and in other follow-ups using the Dental Wear Index (IDD) (TWI – Tooth Wear Index), proposed by Smith and Knight (1984), which classify injuries as wear. which can originate from both erosion and abrasion and attrition. In this index, wear is divided according to severity into: 0 no loss of tooth structure; 1 loss of a layer of enamel; 2 losses of enamel with exposure of 1/3 of dentin; 3 exposures of more than 1/3 of dentin; and 4 exposures of secondary dentin or pulp. Each surface of the tooth that is subject to wear and tear will be evaluated.;Tertiary outcome: Cost-effectiveness. To assess the cost and effectiveness of treatments, the number of clinical sessions required for treatment (per session and the approximate number of hours per session) will be recorded in the patient's file. The main focus of our analysis will be to evaluate the economic effectiveness between two distinct treatment groups: endocrown composite resin crowns and direct composite resin restorations on fiberglass posts. We will use total costs as a primary measure, encompassing costs of direct dental procedures and opportunity costs for each group.
