Furthermore, in a study by Koubi et al. [ 12], Biodentine was used as a posterior restoration and revealed favorable surface properties such as good marginal adaptation until 6 months.
Periapical radiograms showed good marginal bone response and the absence of any residual vertical bone defect (Fig. 4j-l).
Clinically, good marginal adaptation and marginal seal and consequently little marginal discoloration, as well as good wear resistance, were observed, as expressed according to the USHPS criteria.
Cements are considered necessary to obtain durable retention of the restoration and good marginal seal, as well as maintaining original color and marginal outline.
They explained the good marginal integrity of Biodentine with the ability of calcium silicate materials to form hydroxyapatite crystals at the surface.
But at some point extra storeys are no longer a good deal, since marginal costs for more lifts and extra steel to stop the building from swaying in the wind, for example—increase faster than marginal revenues (rents or sales).
Grain sorghum silage can replace corn silage to supplement growing steers without detrimental effects on performance and ruminal fermentation, thus being a good alternative in marginal areas where corn production is agronomically uncertain.
To test this statement, we chose the Milgrom Roberts model.31 The model assumes two stages: At the first stage, there is a monopoly that produces a good with a marginal cost that may be high (c_{h}) or low (c_{l}).
"The strike definitely could be a good thing for some marginal shows," said Preston Beckman, the executive in charge of scheduling for the Fox network.
This finding could result from the fact that, for those workers, financial incentives are not a good proxy for the marginal utility from working.
