Dentist : Do you know?

• Do you know?
• calcium hydroxide introduced by Hermann in 1930
• used in dentistry as:- 1)root canal cement- non-eugenol, calcium- hydroxidnal polymeric resin root canal sealer such as -Sealapex- product of Kerr manufacturing company. 2)biocompatible cement base 3)root canal medicament - causes significant increase in pH of circumpulpal dentin when the compound is placed in root canal. 4)In pulpotomy & Apexification - calcium hydroxide is used because of its predictability in bridge formation & maintainance of vitality of the residual pulp. [in contrast ZOE cement causes persistant chronic nflamatory response when aplied directly to pulp with less likely hood of dentin bridge formation.
• Of a Number of agents studied experimentally by Hunter, Calcium Hydroxide, Magnesium hydroxide, and zinc oxide-eugenol were the only ones that produced dentinal bridging; Hunter conjectured that both calcium & magnesium anionsstimulate bridging because of their high pH and ction appears to be unimportant so long as it remains bland
