MATERIALS USED IN VITAL PULP THERAPY

CALCIUM HYDROXIDE
 Has a pH of 11.5 - 12.5
 Highly basic
 Mild irritant to tissues
 Function – irritates tissues thus inducing formation of tertiary dentine
 For DPC, IPC , Apexification, perforation repair, & weeping canals

MINERAL TRIOXIDE AGGREGATE
 Calcium Phosphate + calcium oxide
 Has a pH of 12.5 – 13
 Disadvantage- very long Setting time – 2 hrs 45mins
 Non-resorbable quality makes it the best sealing material.-superior than CaOH
 For Apexification, perforation repair, & Apicocetomy

GREY MTA –
o Ferric Oxide
o Prevents moisture sensitivity
o So no change in properties
o Best used for Apicocetomy

WHITE MTA –
o No iron content
o Therefore sensitive to moisture
NB : MTA is preferred than CaOH. But choose both if such option available

OTHER CASES WHERE THESE MATERIALS ARE USED:

WEEPING CANALS:-
Irrigants to be used is NaOCl + Iodide Potassium – IRRIGANT
Here the bleeding spot at the apex has to be arrested, hence we place CaOH for 2-3 weeks.

CaOH acts as disinfectant, Helps neutralize acidic exudate, medicament - OBT MATERIAL

USES OF MTA / CaOH
 IPC
 DPC
 Pulpotomy
 Pulpectomy
 Apexogenesis
 Apexification
 Perforation repair
 Internal resorption
