Long-term F release from glass ionomer cements
Journal of Dental Research
|February 1, 1984
Summary
Glass ionomer cements release comparable fluoride levels to silicate cements over one year. This suggests glass ionomers may offer similar anticariogenic benefits, crucial for dental health.
Area of Science:
- Dental Materials Science
- Biomaterials
- Cariology
Background:
- Glass ionomer cements are widely used in dentistry.
- Understanding their fluoride release is key to assessing anticariogenic potential.
- Comparison with traditional dental cements is essential.
Purpose of the Study:
- To quantify fluoride release from commercial glass ionomer cements over 12 months.
- To compare fluoride release patterns of glass ionomers with other dental cements.
- To evaluate the potential anticariogenic properties of glass ionomer cements.
Main Methods:
- Laboratory measurement of fluoride release.
- Testing of three commercial glass ionomer filling cements and three luting cements.
- Comparison with silicate, silicophosphate, and polycarboxylate cements over a 12-month period.
Main Results:
- Glass ionomer cements exhibited consistent fluoride release over 12 months.
- Fluoride release quantity and pattern were similar to silicate cement.
- Silicophosphate cement showed lower fluoride release; polycarboxylate release was negligible after initial days.
Conclusions:
- Glass ionomer cements demonstrate sustained fluoride release.
- Their fluoride release profile is comparable to that of silicate cement.
- These findings suggest glass ionomer cements possess anticariogenic properties similar to silicate cements.

01:24Hydration of Cement
Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...
01:29Strength and Heat of Hydration
The hydration of cement is an exothermic reaction in which heat is generated as cement hydrates. This heat of hydration is critical to cement's strength development. The rate at which this heat is generated affects the temperature rise, with a majority of the heat being released early in the hydration process, half within the first three days, and about 75% within the first week.
The heat of hydration for each cement compound is significant; for instance, tricalcium aluminate (C3A) and...

01:12Setting Time of Cement
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...
01:17Soundness of Cement
The soundness of cement refers to the ability of cement paste to retain its volume after setting. Unsound cement can lead to expansion and structural damage due to the presence of free lime, magnesia, and calcium sulfate. Free lime hydrates very slowly, expanding and causing unsoundness, which is difficult to detect because it intercrystallizes with other compounds. Magnesia also reacts with water, forming crystals that can disrupt the cement's structure. Calcium sulfate can create ettringite,...
01:21Types of Cement I
Portland cement comes in several types, each with distinct properties and applications based on their chemical composition and hydration characteristics:
Type I (Ordinary Portland Cement) is widely used for general construction where special properties are not required. It has moderate sulfate resistance and heat of hydration.
Type II (Modified Cement) offers moderate resistance to sulfate attack and a lower rate of heat development compared to Type I. It is suitable for structures in...

01:20Curing of Concrete
The hydration of cement takes place within the water-filled capillary pores. However, environmental elements can disrupt this process by evaporating water from the concrete surfaces. Sealed concrete with a water-cement ratio below 0.5 experiences self-desiccation, leading to water loss. The water loss in concrete is mitigated by curing. This technique involves keeping the concrete saturated to maintain the necessary temperature and moisture conditions, to optimally fill the spaces in the cement...
