Article Abstract
Purpose: To evaluate the efficacy of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) in the remineralisation of white-spot lesions in 80 anterior teeth of children aged 5-13 years enrolled in public schools of the city of Botucatu, São Paulo, Brazil.
Materials And Methods: The study sample consisted of 36 individuals divided into 4 groups: G1. control (placebo paste); G2. fluoride gel; G3. CPP-ACP; G4: CPP-ACP + fluoride. Each product was applied twice by a calibrated examiner with a week of interval between. Lesions were monitored with a DIAGNOdent Pen before the first application, before the second application, and 1 and 3 months after the first application. To evaluate the lesion intensity, the Friedman test was applied, and to compare experimental groups, the Kruskal-Wallis test was applied. The analyses were complemented with the Dunn test and the level of significance was 5%.
Results: At the end of the 90-day trial, the use of CPP-ACP and fluoride showed comparable results in terms of remineralisation. The best white-spot lesion remineralisation was observed when CPP-ACP and fluoride were combined.
Conclusion: The use of CPP-ACP is a good alternative for the remineralisation of white-spot lesions. The effect can be improved when this product is applied in combination with fluoride.

White spot lesions (WSLs) are the most common complication of orthodontic treatment, compromising dental health and significantly affecting aesthetics. To address this clinical challenge, this study aims to develop a dual-functional therapeutic strategy that simultaneously promotes the remineralization of demineralized enamel and inhibits the activity of cariogenic bacteria, thereby achieving effective prevention and treatment of WSLs. A hollow double-shell structured CuO@N/C nanozyme (H-CuO@N/C) was synthesized using a one-step hydrothermal method.

Background: Considering that a single passive application of hydrochloric acid (HCl) as a resin infiltration pretreatment can remove between 20 and 45 µm of enamel and cause etching that extends up to 2 mm beyond the white spot lesions (WSLs), it is plausible that its repeated and active applications could result in a greater amount of dental tissue being removed.
Objective: To evaluate the enamel surface loss and micromorphology after etching with 15% HCl using two application methods (passive-P and active-A) and varying numbers of applications (C-placebo - 120 s; 1x HCl - 120 s; 2x HCl - 120 s + 120 s; 3x HCl - 120 s + 120 s + 120 s).
Methodology: Bovine incisors with ≤0.

Objective: To develop near-infrared (NIR) laser-activated PLGA-PDA core-shell nanohybrids encapsulating Ag/CuO nanoparticles for simultaneous photothermal antibacterial therapy and sustained Ag/Cu release, and to evaluate their bactericidal efficacy against Streptococcus mutans and preventive potential in orthodontic white spot lesions.
Methods: Ag/CuO nanoparticles were encapsulated in PLGA/PDA nanospheres via a double-emulsion and self-polymerization approach. The resulting core-shell particles were fully characterized for composition, size distribution, zeta potential, morphology, photothermal performance, release kinetics, and cytocompatibility.

Amorphous calcium phosphate (ACP) is a well-established bioceramic material known to promote the remineralization of dental hard tissues. White spot lesions (WSLs) represent the initial stage of enamel demineralization and are frequently observed in patients with fixed orthodontic appliances or inadequate oral hygiene. Although recommendations for remineralizing agents include both the prevention of lesion progression and the stimulation of tissue remineralization, the clinical efficacy of ACP-based materials remains under debate.

Introduction: Clear aligner orthodontic treatment provides a hygienic and esthetic alternative to fixed appliances; however, the required resin attachments can promote plaque accumulation and increase the risk of white-spot lesions in enamel. This study aimed to develop a novel resin-based antibacterial and bioactive orthodontic clear aligner attachment and evaluate its mechanical and antibacterial properties.
Methods: A resin matrix composed of urethane dimethacrylate (UDMA) and triethylene glycol divinylbenzyl ether (TEG-DVBE) was modified with 3% dimethylaminododecyl methacrylate (DMADDM) for antibacterial effects and nano-amorphous calcium phosphate (NACP) to support remineralization.
