The phrase "a marginal gap in" is correct and usable in written English.
It can be used to describe a small or insignificant difference or space in a particular context, often in discussions about data, research, or analysis.
Example: "The study revealed a marginal gap in the performance of the two groups, suggesting that further investigation is needed."
Alternatives: "a slight difference in" or "a minor discrepancy in".
He states that, "What started as a marginal gap between actual operating profits and ones reflected in the books of accounts continued to grow over the years.
"What started as a marginal gap between actual operating profit and the one reflected in the books of accounts continued to grow over the years.
McLean and von Fraunhofer stated that a marginal gap of about 100 μm does not cause any clinical problems in a study observing 1,000 dental restorations performed over more than 5 years, concluding that the clinically allowable maximum marginal discrepancy was 120 μm [ 13].
If TPC is considered, Algorithm 2 has a marginal gap of outage probability compared to Algorithm 1.
Another previous study evaluated that a marginal gap up to 100 μm was clinically acceptable, while still another extended the clinically acceptable marginal gap to 200 μm [ 14, 15].
The FDI criteria for marginal adaptation accept the total length of visible enamel as sound and only considers a marginal gap of >0.25 mm or exposed dentine/base as a condition for restoration failure [ 1].
This condition, considered by the evaluators to be either a marginal gap (failure) or not (success), was the main reason influencing their disagreement about the survival outcome.
It has been shown that nanoleakage can occur in the absence of marginal gaps in biomaterial dentin interfaces [100], which led to the conclusion that host-derived proteinases make an important contribution to the degradation of incompletely infiltrated collagen in bonded dentin [101], even when bacteria are not present [102,103].
This has been demonstrated to facilitate water sorption and hydrolytic degradation [26], even in the absence of a visible marginal gap at the tooth biomaterial interface [27].
However, an inverse step at the cavity margin may also be mistaken as a true marginal gap, exposing enamel and/or dentine.
