Summary
Choosing dental sealants can be complex due to varying properties like caries prevention and fluoride release. Resin-based and glass ionomer sealants show similar effectiveness in preventing fissure caries in permanent molars over 24 months.
Area of Science:
- Dentistry
- Dental Materials Science
Background:
- Dental sealant selection involves considering caries preventive effects, fluoride release, and retention rates.
- Fissure sealant materials are broadly categorized into resin-based and glass ionomer types.
Purpose of the Study:
- To compare the effectiveness of different fissure sealant materials in preventing caries.
- To analyze the properties of resin-based versus glass ionomer sealants.
Main Methods:
- Literature review of studies comparing resin-based and glass ionomer fissure sealants.
- Analysis of sealant properties including retention and fluoride release.
Main Results:
- Fluoride-releasing resin sealants demonstrate superior material retention compared to glass ionomers.
- Despite differences in retention, both sealant types exhibit comparable effectiveness in preventing fissure caries in permanent molars over a 24-month period.
Conclusions:
- While resin-based sealants offer better retention, the clinical effectiveness for caries prevention in permanent molars is similar between resin-based and glass ionomer sealants over 24 months.
- Dentists should weigh material retention against comparable caries prevention when selecting fissure sealants.

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

01:19Members Made of Elastoplastic Material
405
The behavior of elastoplastic materials under bending stresses, particularly in structural members with rectangular cross-sections, is crucial for predicting material responses and understanding failure modes. Initially, when a bending moment is applied, the stress distribution across the section follows Hooke's Law and is linear and elastic. This distribution means the stress increases from the neutral axis to the maximum at the outer fibers, up to the elastic limit.

3.8K
Within the human body, a complex and detailed system of trillions of cells works in unison to sustain life. Each cell houses a nucleus, which contains 46 chromosomes divided into 23 pairs. Chromosomes are highly coiled structures made of the genetic material DNA. These chromosomes are essential carriers of genetic information, with half inherited from the mother through her egg and the other half from the father's sperm, combining to create the unique genetic makeup of an individual.

In analyzing a structural member composed of two different materials with identical cross-sectional areas, it is crucial to understand how their distinct elastic properties affect the member's response under load. The analysis involves assessing stress and strain distributions using the transformed section concept, which accounts for variations in material properties.

02:59Biological Effects of Radiation
18.0K
All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they...

02:19Buffer Effectiveness
55.4K
Buffer solutions do not have an unlimited capacity to keep the pH relatively constant . Instead, the ability of a buffer solution to resist changes in pH relies on the presence of appreciable amounts of its conjugate weak acid-base pair. When enough strong acid or base is added to substantially lower the concentration of either member of the buffer pair, the buffering action within the solution is compromised.
The buffer capacity is the amount of acid or base that can be added to a given volume...
