Summary
The compatibility of self-etching bonding systems (SEBSs) with resin luting cements (RLCs) varied significantly. One-step SEBSs showed incompatibility with chemical-curing RLCs, while two-step SEBSs were compatible.
Area of Science:
- Dental Materials Science
- Adhesive Dentistry
Background:
- Resin luting cements (RLCs) and self-etching bonding systems (SEBSs) are crucial in modern restorative dentistry.
- Evaluating their compatibility is essential for predictable clinical outcomes.
Purpose of the Study:
- To assess the in vitro compatibility between five SEBSs and two RLCs using a dentin shear bond test.
- To determine the influence of curing mode on the bond strength.
Main Methods:
- Five SEBSs (two one-step, three two-step) and two RLCs (dual-cure and self-cure) were tested.
- 150 human molars were divided into ten groups for shear bond strength testing after seven days of storage.
- Failure modes were analyzed post-testing.
Main Results:
- Significant differences in shear bond strength (SBS) were found based on RLC curing mode and adhesive type.
- One-step SEBSs (Xeno III, One Up Bond F) were incompatible with the self-cure RLC.
- Two-step SEBSs demonstrated compatibility with both self-cure and dual-cure RLCs.
Conclusions:
- The choice of SEBS and RLC curing mode critically impacts bond strength.
- Two-step SEBSs offer greater compatibility with various RLC curing modes compared to one-step systems.
- A positive correlation exists between adhesive pH and SBS.

Strength of Cement
Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in ASTM C...

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...
Types of Cement II
Portland blast-furnace cement is made by blending Portland cement clinker with granulated blast-furnace slag, which accounts for 25 to 65 percent of the cement's weight. Despite its similarities to ordinary Portland (Type I) cement in terms of fineness and setting times, its early strength is lower, though it achieves comparable strength later on. It's particularly suited for mass concrete structures and marine environments due to its lower heat of hydration and superior sulfate resistance.
Accelerators
Accelerators in concrete serve as admixtures to speed up the hardening process, enabling the concrete to achieve early strength faster. Although accelerators do not necessarily impact the time it takes concrete to set, they reduce this time in practice. A common accelerator is calcium chloride, which is particularly useful for hastening early strength development in cold weather or for rapid repair jobs that require quick heat generation after mixing.

Testing Water Quality
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...
Complexometric Titration: Ligands
Different monodentate and polydentate ligands are used as complexing agents in complexometric titration reactions. The formation of complexes by mono- and bidentate ligands involves two or more intermediate steps, limiting their use as complexing agents. In comparison, polydentate ligands can form complexes with metal ions in a single-step process, facilitating sharper end points. This means polydentate ligands, such as amino carboxylic acid derivatives, are most commonly employed in...
