Summary
Resin cement demonstrated superior retention strength for stainless-steel crowns on primary molars compared to glass ionomer and resin-modified glass ionomer cements, enhancing crown stability.
Area of Science:
- Pediatric Dentistry
- Dental Materials Science
- Restorative Dentistry
Background:
- Stainless-steel crowns (SSCs) are widely used in pediatric dentistry.
- Cementation failure is a primary cause of SSC loss.
- The selection of luting cement significantly impacts SSC retention.
Purpose of the Study:
- To compare the retention strength of SSCs luted with three different cement types.
- Evaluate glass ionomer cement (GIC), resin-modified glass ionomer cement (RMGIC), and resin-based cement for SSC retention.
Main Methods:
- 45 extracted primary molars were prepared for SSCs.
- Teeth were randomly assigned to GIC, RMGIC, or resin cement groups.
- Crown retentive strength was measured using a Universal Testing Machine after 24h storage in artificial saliva.
Main Results:
- Resin cement (GC G-CEM One) exhibited significantly higher retentive strength (269.25 ± 11.28) compared to RMGIC (GC FujiCEM, 194.78 ± 13.03) and GIC (GC GOLD Label 1, 230.30 ± 13.46).
- GIC showed significantly higher retention than RMGIC (P < 0.001).
Conclusions:
- Resin cement provides significantly improved retention for SSCs on primary molars.
- This finding suggests resin cements are a favorable choice for enhancing SSC stability and longevity.

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...

01:12Bonding and Strength of Aggregate
265
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...

01:18Porosity in Cement Paste
233
The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.

01:14Testing Water Quality
192
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...
