摘要：
An apparatus (100, 100′) is configured such that passage of a fluid (30) through an open port of a distal tip (112, 112′) enables detection of a substance (116) that may be present on a surface (31, 33), e.g., a surface of a tooth, based on measurement of a signal correlating to a substance at least partially obstructing the passage of fluid (30) through the open port. The apparatus (100, 100′) includes a proximal pump portion (124) and at least one distal probe portion (110) configured to be immersed in another fluid (11), e.g., water in toothpaste foam. A corresponding system (3000) includes one or two such apparatuses (3100, 3200). A method of detecting the presence of a substance on a surface includes probing an interaction zone (17) for at least partial obstruction of flow of the second fluid medium (30) through a distal probe tip.
