Department of Preventative and Restorative Dental Sciences, UCSF School of Dentistry, San Francisco, CA, USA. Electronic address:

Objectives: The study evaluates the efficacy to remineralize artificial and natural dentin lesions through restorative dental procedures that include the Polymer-Induced Liquid Precursor (PILP) method comprising polyaspartic acid (pAsp).

Methods: Novel ionomeric cement compositions based on bioglass 45S5 and pAsp mixtures, as well as conditioning solutions (conditioner) containing 5 mg/ml pAsp, were developed and tested on demineralized dentin blocks (3-4 mm thick) on shallow and deep lesions with the thickness of 150 µm ± 50 and 700 µm ± 50, respectively. In the first treatment group, 20 µl of conditioner was applied to demineralized shallow (n = 3) and deep (n = 3) lesion specimens for 20 s before restoration with glass ionomer cement (RMGIC).

Anterior Veneer Restorations - An Evidence-based Minimal-Intervention Perspective.

J Adhes Dent 2021 Apr;23(2):91-110

Purpose: The goals of this review are (1) to describe the evidence behind the use of ceramics vs composite resin to restore teeth with anterior veneers using a minimally-invasive strategy; and (2) to discuss the choice of materials and techniques for anterior veneer restorations.

Overview: In recent years new adhesive restorative materials and techniques have been introduced in dentistry, including nanofilled composite resins for direct restorations, new ceramic materials that combine esthetics and strength, and polymer/ceramic materials for indirect restorations that are fabricated chairside using CAD/CAM technology, allowing the dentist to design, mill, and cement the restoration in one session. In spite of the novelty and new technology behind the introduction of new materials, the available evidence that backs some of these materials does not justify their use over similar materials or techniques that have been used by dentists for some years.

Sci Rep 2021 Apr 5;11(1):7496. Epub 2021 Apr 5.

Department of Pediatric Dentistry, Piracicaba Dental School, University of Campinas-UNICAMP, Limeira Avenue 901, Piracicaba, SP, CEP 13414-903, Brazil.

This quasi-experimental study sought to investigate if the mechanical control of biofilm (3-times-a-day) modifies the saliva's ability to buffer the oral environment after 20% sucrose rinse (SR) in children with early childhood caries (ECC). Here, SR reduced the saliva's pH in both groups and the mechanical control of biofilm had a greater effect on this parameter after SR in CF children. The mechanical control of biofilm evidenced a higher buffering capacity in CF children before SR, which was not observed after SR. Read More
