Current literature lacks robust evidence on the benefits of omitting polyacrylic acid pre-conditioning in glass ionomer cement (GIC) restorations for primary teeth. The present article aims to describe a randomized controlled non-inferiority trial which sought to evaluate the clinical performance of occlusal and occluso-proximal restorations using encapsulated glass ionomer cement without prior application of 25% polyacrylic acid. Methodology: Children aged 3 to 9 years, enrolled in public schools in Rio de Janeiro, were randomly assigned to two groups: experimental and control. In the experimental group, encapsulated Riva Regular® glass ionomer cement (SDI – Australia) will be applied after a placebo simulating polyacrylic acid. In the control group, the same material will be used following standard pre-conditioning with 25% polyacrylic acid. The groups were further stratified according to cavity type (occlusal or occluso-proximal), and all procedures were performed using the Atraumatic Restorative Treatment (ART) technique. Follow-ups were conducted at 6, 12, 18, and 24 months, with the primary outcome being the restoration survival rate at 24 months. Conclusion: Omitting the pre-conditioning step with 25% polyacrylic acid may be a viable alternative for GIC restorations in primary teeth, potentially without compromising clinical efficacy compared to the conventional technique. Additionally, this simplified approach may enhance acceptance among professionals by reducing clinical procedure time.
