1Department of Endodontics, Faculty of Dentistry, Dicle University, Diyarbakir, Turkey.
Summary
Heating irrigation solutions significantly enhances bioceramic sealer bond strength to root canals. Ethylenediamine tetra-acetic acid (EDTA) solutions showed superior bonding compared to Dual Rinse® HEDP, with higher bond strengths observed in the middle root sections.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Irrigation solution temperature impacts root canal sealer efficacy.
- Understanding these effects is crucial for optimal endodontic treatment outcomes.
Purpose of the Study:
- To investigate how different irrigation solution temperatures affect the bond strength of bioceramic-based root canal sealers.
- To compare the bond strength performance of sodium hypochlorite (NaOCl) with ethylenediamine tetra-acetic acid (EDTA) and glycolic acid (GA), as well as Dual Rinse® HEDP.
Main Methods:
- Root canal sealers were tested using push-out tests after irrigation with NaOCl/EDTA, NaOCl/GA, or Dual Rinse® HEDP mixtures at 22°C and 37°C.
- Three-way ANOVA was employed to analyze the bond strength data.
Main Results:
- Increased irrigation solution temperature significantly enhanced the bond strength of bioceramic-based sealers.
- EDTA solutions demonstrated significantly higher bond strength compared to Dual Rinse® HEDP.
- Bond strength was lower in the apical region than in the middle root sections.
Conclusions:
- Elevated temperatures of irrigation solutions positively influence the bond strength of bioceramic sealers.
- EDTA is a more effective irrigant for enhancing sealer bond strength than Dual Rinse® HEDP.
- Root canal region influences sealer bond strength, with apical sections exhibiting lower values.

01:29Strength and Heat of Hydration
210
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...

01:21Masonry in Cold and Hot Weather Conditions
80
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

01:14Testing Water Quality
103
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...

01:20Hot Weather Concreting
53
Concreting at elevated temperatures accelerates the hydration process, leading to quicker setting but potentially reducing the long-term strength of the concrete structure. Additionally, low air humidity fosters rapid moisture loss from the concrete, resulting in reduced workability, pronounced plastic shrinkage, and a higher likelihood of crazing.

01:24Hydration of Cement
197
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...

01:22Waterproofing and Anti-Bacterial Admixtures in Concrete
73
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.
