Mg whitlockite

Question 7

Mandibular post rich in?

Answer 7

Mg whitlockite…

Pn – POST Teeth r really MAGNIFICIENT (Mg) given their Strength…!

Question 8

Concept of calculus formation?

Answer 8

1. EPITACTIC Concept AKA HETEROGENEOUS Calcification - MOST ACCEPTED THEORY!!

Seeding agents induce SMALL FOCI of calcification ——–+ which enlarge n coalesce ———–+ calcified mass…

2. Mineral precipitation concept-Colloidal proteins in saliva bind calcium and phosphate ions n maintain a SUPERSATURATED solution ————+ ppt
   Bact also secrete PHOSPHATASE…. hydrolyses ORGANIC PHOSPHATES…

0.1 to 0.15 % per day

Answer 10

10 wks to 6 months ( or say 3 to 6 months )
