Bonding and Strength of Aggregate01:12

Bonding and Strength of Aggregate

The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...

A novel fluoride-containing dental adhesive enhanced microtensile bond strength after water storage and created an inhibition zone against secondary caries. This adhesive also showed improved degree of conversion over time.

Area of Science:

  • Dental Materials Science
  • Adhesive Dentistry
  • Caries Prevention

Background:

  • Dental adhesives are crucial for restoring tooth structure.
  • Secondary caries at the restoration-dentin interface remains a clinical challenge.
  • Fluoride-releasing materials offer potential for caries inhibition.

Purpose of the Study:

  • To assess the impact of a fluoride-containing adhesive on bond strength.
  • To evaluate its efficacy in inhibiting secondary caries in vitro.
  • To determine the degree of conversion of different adhesives over time.

Main Methods:

  • Microtensile bond strength (microTBS) testing after 24h and 3 months of water storage.
  • In vitro secondary caries inhibition assessment using polarized light microscopy (PLM) after an acid challenge.

Detection and Removal of Tooth-Colored Composite Resin Using the Fluorescence-Aided Identification Technique

Published on: July 27, 2022

  • Degree of conversion (DC) measurement using Fourier Transform-Infrared spectroscopy (FTIR).

    • Main Results:

    • The fluoride-containing adhesive (PB) showed increased microTBS after 3 months compared to 24h.
    • An inhibition zone against acid attack was observed only with the PB adhesive.
    • PB demonstrated a significant increase in DC after 1 month, unlike other tested adhesives.

    Conclusions:

    • Fluoride-containing adhesives can improve long-term bond durability and provide secondary caries protection.
    • The tested fluoride adhesive exhibits promising properties for clinical application.
    • Further research should explore the clinical translation of these findings.
