CALCIUM HYDROXIDE CEMENT

Herman (1930) introduced calcium hydroxide for pulp capping.

1. Two paste system containing base

• Light cured system Two paste system
• Single paste in syringe form
• Powder form

• Glycol salicylate; 40% – reacts with Ca (OH)2 and ZnO
• Calcium sulphate
• Titanium dioxide – inert fillers, pigments
• Calcium tungstate or barium sulphate – provides radiopacity

• Calcium hydroxide 50% – principle reactive ingredient
• Zinc oxide – 10%
• Zinc stearate; – 0.5% – accelerator
• Ethylene toluene
• Sulfonamide – 39.5% – oily compound, acts as carrier

Calcium hydroxide cements have poor mechanical properties.

Calcium hydroxide root canal sealing pastes

• Effective antibacterial property without irritation

USES OF CALCIUM HYDROXIDE:-

• Direct and indirect pulp capping.
• Apexification and apexogenesis.
• An intracanal medicament.
• Treatment of avulsed teeth.
• Treating root fractures.
• Treatment of perforations.
• Treatment of intraoral external resorption.
• Root canal filling material for primary molars.

• No tenderness to percussion.
• No abnormal mobility.

• History of spontaneous pain.
• Tenderness to percussion.
• Abnormal mobility.
• Root resorption.

• After drying the cavity calcium hydroxide is placed.
• The cavity is sealed with an interim restoration
• Small pulp exposure produced during cavity
• Large pulp exposure.
• Rubber dam application keeps the pulp free from contamination
• Complete caries should be excavated
• The exposure site is dried and calcium hydroxide is placed over the exposure.
• The tooth is restored with on interim restoration
• Preservation of vitality of the radicular pulp
• Relief of pain in patients with acute pulpalgia
• Vital tooth with healthy periodontium
• A restorable tooth
• Absence of spontaneous pain
• Atleaast 2/3 of root length should be present
• Irreversible pulpitis
• Swelling
• Presence of fistula
• External root resorption
• Internal root resorption
• Periapical abscess
• Presence of pulp calcification
• Rubber dam is applied
• Access is gained into the pulp chamber
• The coronal portion of pulp is removed with a sharp spoon excavator
• Calcium hydroxide paste is applied to the pulp stump.
• A zinc phosphate cement base is applied

Calcium hydroxide pulpotomy outcomes in primary teeth

• Calcium hydroxide pulpotomies in primary teeth only a 31% success.
• Administration of local anesthesia
• Dry the canal with absorbent points-
• Recall every six weeks.
• Usually the calcium hydroxide dressing is changed every 2-3 months.
• Calcium hydroxide + methylcellulose
• Calcium hydroxide + sterile water
• Calcium hydroxide + CMCP
• Calcium hydroxide + cresatin
• Calcium hydroxide in RCT:-
