K190091 is an FDA 510(k) clearance for the Diapaste. Classified as Resin, Root Canal Filling (product code KIF), Class II - Special Controls.

Submitted by DiaDent Group International (Cheongju-Si, KR). The FDA issued a Cleared decision on March 27, 2020 after a review of 434 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Dental FDA review panel, regulated under 21 CFR 872.3820 - the FDA dental device regulatory framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Dental submissions.
