Summary

Flowable composites show comparable shear bond strength to orthodontic adhesives, making them suitable for direct bonding. While one adhesive had higher pullout resistance, flowables offer a viable alternative for lingual retainers.

Bonding and Strength of Aggregate

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...

Background:

Orthodontic adhesives are crucial for direct bonding of appliances.
Flowable composites offer handling advantages but require mechanical property evaluation.
Assessing shear bond strength (SBS) and pullout resistance is vital for clinical efficacy.

Purpose of the Study:

To compare the shear bond strength (SBS) and pullout resistance of flowable composites against a standard orthodontic adhesive.
To test the null hypothesis of no significant differences between these materials.
To determine the suitability of flowable composites for direct bonding applications.

Main Methods:

Four materials (Light Bond, FlowTain, Filtek Supreme, Tetric Flow) were tested.

Roughness Impact of Piezoelectric Dental Scaler on Two Distinct Flowable Composite Filling Materials

Published on: January 10, 2025

SBS was measured after application to 15 human teeth enamel surfaces.

Pullout resistance was assessed by embedding a wire in 15 samples per material.

Main Results:

No statistically significant differences were found in shear bond strength (SBS) among the tested materials (P > .05).
Light Bond exhibited significantly higher pullout resistance than Filtek Supreme and FlowTain (P < .01).
No significant differences in pullout resistance were observed among flowables or between Light Bond and Tetric Flow.

Conclusions:

The null hypothesis was rejected based on pullout resistance findings.
Flowable composites demonstrate satisfactory SBS and pullout values, comparable to standard orthodontic resins.
Flowable composites are a viable alternative for direct bonding of lingual retainers.
