Resin-Based Materials Protect Against Erosion/Abrasion-a Prolonged In Situ Study
Operative Dentistry
|January 11, 2019
Summary
Resin-based materials effectively protect previously eroded enamel from further damage during prolonged erosive and abrasive challenges. This study demonstrates their protective role, offering a promising additional treatment for dental erosion prevention.
Area of Science:
- Dental materials science
- Preventive dentistry
- Biomaterials
Background:
- Dental erosion is a growing concern, and while patient compliance with preventive measures is crucial, additional therapeutic interventions are needed.
- Resin-based materials offer a potential adjunctive treatment to inhibit the progression of dental erosion on compromised enamel surfaces.
Purpose of the Study:
- To evaluate the protective effect of various resin-based materials against prolonged erosive and abrasive challenges on previously eroded bovine enamel.
- To compare the efficacy of resin infiltrants, sealants, and adhesives in preventing enamel loss under simulated oral conditions.
Main Methods:
- An in situ study design utilizing bovine enamel blocks subjected to erosion (0.01 M HCl, pH 2.3) and erosion + abrasion (with fluoride toothpaste slurry) for 20 days.
- Treatments included resin infiltrant (Icon), sealant (Helioseal Clear), adhesive (Adper Scotchbond Multi-Purpose Plus), and a control (no treatment).
- Enamel and material loss were quantified using profilometry, with data analyzed via ANOVA and Tukey's test.
Main Results:
- All tested resin-based materials provided significant protection against enamel loss compared to the untreated control group (p=0.001).
- The resin infiltrant group exhibited a thicker material layer on the enamel surface.
- No significant difference in wear was observed between the erosion-only and erosion + abrasion conditions (p=0.869).
Conclusions:
- Application of resin-based materials, including infiltrants, sealants, and adhesives, effectively protects previously eroded enamel from further degradation.
- These materials represent a viable additional treatment strategy to mitigate dental erosion progression in a clinical setting.

01:23Abrasion Resistance of Concrete
552
Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.

01:25Transmission-based Precautions II: Airborne and Protective Environment
1.9K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

01:09Methods for Studying Drug Absorption: In situ
676
In situ experiments, such as the Doluisio method and Single-Pass Perfusion technique, provide critical insights into drug uptake by simulating in vivo conditions for drug absorption.
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...

01:16Zones of Protection
794
In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker.
Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...

01:23Radial System Protection
442
Radial systems employ time-delay overcurrent relays to reduce load interruptions. When a fault occurs, the nearest breaker opens first, while upstream breakers remain closed due to longer delay settings. This approach ensures minimal disruption to the rest of the system.
In a radial system with a fault downstream of the third breaker, ideally, only the third breaker will open, isolating the fault and interrupting the load connected beyond it. The second breaker has a longer delay setting,...
