In addition,the description of SDF's application technique, "can be applied with a micro-brush", may have required additional clarification, for example, that the excavation of soft dentin is not needed because SDF will react with the tooth surface and create a layer of silver protein that resists bacterial acids and promotes the formation of hydroxyapatite and fluorapatite. (15,17) Some respondents raised concerns about the legal ambiguity regarding the use of SDF "off-label" to treat dental caries.

In profile C, the weathered shale and protolith portions contained fluorapatite. Based on the XRF analysis (Table 1), Si content increases from 52.3% to 65.2% in profile A and from 49.1% to 70.5% in profile C.
Phosphate minerals on Earth, like fluorapatite and whitlockite, take their time to dissolve, they are also not readily incorporated into a water-based solution, which is why their concentration are relatively low.
