Preformed metal crowns placed by Hall technique for restoring primary molars have an optimal survival? - a Systematic Review and Meta-analysis protocol

Abstract

Background: Unsuccessful restorative treatment of carious lesions in deciduous molars remains a priority for clinicians to resolve when caring for children's dentition. However, regardless of the material or technique used, standard restorative treatments continue to fail and present low survival rates. In an effort to solve these problems, a non-invasive technique known as the Hall Technique was developed with reduced adverse effects and is being studied over the last years, presenting great success in comparison with other restorative techniques. Thus, this systematic review and meta-analysis aim to address the question concerning the survival of preformed metal crowns using the Hall Technique for restoring deciduous molars.Methods: Electronic databases and other sources, such as gray literature will be searched. Randomized controlled trials (RCTs), and Non-Randomized studies of interventions (NRSI) will be included that assess the use of preformed metal crowns using the Hall Technique on primary molars. The outcome will be the cumulative survival rate of preformed metal crowns applied according to the Hall Technique. Two independent reviewers will perform screening, study selection, data extraction, risk of bias, and certainty of evidence assessment. Any discrepancies in opinion will be resolved by a third reviewer who is considered to be an expert in the field. Assessment of the risk of bias of included studies will be evaluated by RoB 2 and ROBINS-I tools. The certainty of evidence will be determined using the GRADE tool. Methodological heterogeneity across studies will be evaluated to determine the best model for the meta-analysis.Discussion: To the best of our knowledge, no systematic review has addressed this gap directly. Findings obtained from the review will be valuable in the decision-making process regarding the use of Hall Technique preformed metal crowns for restoration of decayed primary molars.

Sobrevida da Hall Technique para restaurar molares deciduos cariados - Uma revisão sistemática e meta-análise de braço único

“…Data extraction was carried out by the same reviewers for pre-specified items (74) Restorative treatment was considered a success when the crowns placed were considered satisfactory, with no signs or symptoms of pulpal pathology, when no additional intervention was required after cementation and when the tooth exfoliated without failure. When the crown was lost, or when there were signs or symptoms of reversible or irreversible pulpitis after the crown was cemented, and further treatment was required, it was considered a failure.…”
