Dentine is a biomineralization of microchannels of a connective tissue composed by the mineral dahllite
--[ca.sub.5][(P[O.sub.4]).sub.3](OH)--, arranged in a proteinaceous collagen matrix.
The main mineralogical constituent of a rhinolith is formed by mineral whitlockite (Ca3 (PO4)2) and the remaining part is formed by carbonated apatite (dahllite
) and mineral apatite (Ca5 (OH, F, CI) (PO4)3).
These usually consist of calcium stearate, whitlockite, or dahllite
, as has been determined by previous chemical and mineral analyses (7, 8).
Urinary stones maybe composed of calcium oxalate monohydrate (COM, whewellite), calcium oxalate dihydrate (COD, weddellite), carbonate apatite (CA, dahllite
), ammonium urate, magnesium ammonium phosphate (PAM, Struvite), calcium hydrogen phosphate dihydrate (brushite), uric acid (AU0 anhydrous form and AU2 dihydrate form, uricite) and its salts, cystine, xanthine, 2,8-dihydroxyadenine, and drugs .

The paste crystallizes largely as carbonated apatite, or dahllite
, a mineral that occurs naturally in the human skeleton.
