The objective of this work was to examine osteoblast-like cell attachment and morphology in vitro to osteoceramic materials with three different surface morphologies.
Osteoceramic composite disks were fabricated from tricalcium phosphate and magnesium-aluminate spinel (MgAl2O4) in a 50 vol% ratio. The disks were prepared with three different surface morphologies, including as-fired (irregular), etched (rough), or polished through 1 mm diamond paste (smooth). Osteoblast-like cell cultures were plated onto the prepared disks for 2 h, and the number of attached cells was determined. ANOVA and Student Newman-Kuels tests were used to test for significant differences in cell attachment (p < 0.05). SEM was used to visually evaluate the nature of the cellular adaptation on the osteoceramic surfaces.
Some additional surface roughening resulted from the interaction between the osteoceramic disks and the biological culture media during the attachment assay. A statistically larger number of cells was found to be attached to the etched osteoceramic surfaces compared to the as-fired and polished osteoceramic surfaces or the tissue culture plastic control. Cellular adaptation was extensive on all three osteoceramic surfaces at 2 h.
These results are consistent with previous in vivo work and continue to support the hypothesis that osteoceramic materials have potential for implants and bone substitute materials.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 07 February 2017.
All research outputs
#9,514,662
of 27,774,969 outputs
Outputs from Dental Materials
#259
of 1,128 outputs
Outputs of similar age
#22,481
of 99,711 outputs
Outputs of similar age from Dental Materials
#1
of 2 outputs
Altmetric has tracked 27,774,969 research outputs across all sources so far. This one is in the 42nd percentile – i.e., 42% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,128 research outputs from this source. They receive a mean Attention Score of 4.0. This one is in the 44th percentile – i.e., 44% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 99,711 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 2 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
