<u>Option: A</u>
<u>Explanation:</u>
- A significant element of normal bone and teeth and an essential ingredient.
- Hydroxyapatite compensates the mineral bone and teeth matrix.
- It is hydroxyapatite which brings its stiffness to bones and teeth.
- The inflammation triggered by crystals with hydroxyapatite was referred to as crystal disease with hydroxyapatite.
- Hydroxyapatite, also termed hydroxylapatite, is a found naturally in calcium apatite mineral type.
- A well-recognized unexplained etiological systemic problem named as "Hydroxyapatite crystal deposition disease (HADD)" has been caused by para-articular and/or intra-articular HA crystal deposition.
