✅ Pulp Therapy Techniques

➤ Indirect Pulp Treatment (IPT)
IPT is indicated when deep caries is present but the tooth remains vital and asymptomatic. Selective caries removal minimizes pulp exposure and promotes remineralization. High-fluoride glass ionomer and resin-modified glass ionomer (RMGI) are widely used as liners.

➤ Direct Pulp Cap (DPC)
Used when a small mechanical pulp exposure occurs. Bioceramics like MTA and Biodentine create a durable dentin bridge and exhibit excellent biocompatibility.

➤ Pulpotomy
Indicated in cases of carious pulp exposure with preserved radicular pulp vitality. Popular medicaments include MTA, Biodentine, and historically formocresol, although the latter is no longer recommended due to toxicity concerns.

➤ Pulpectomy
Indicated for irreversible pulpitis or necrosis. It consists of removing necrotic tissue and obturating canals with resorbable materials such as iodoform-based pastes (Vitapex, Metapex) or zinc oxide–eugenol.

➤ Apexogenesis & Apexification in Young Permanent Teeth
Although not used in primary teeth, they are fundamental when treating immature permanent teeth with open apices.

📌 Recommended Article :

Dental Article 🔽 Understanding Pulpal Diseases: Reversible Pulpitis, Irreversible Pulpitis, and Pulp Necrosis in Adults and Children ... Pulpal diseases represent a continuum of inflammatory conditions that range from reversible pulpitis to irreversible pulpitis and finally to pulp necrosis.

✅ Materials Used in Pulp Therapy

➤ Mineral Trioxide Aggregate (MTA)
Known for high biocompatibility, antibacterial properties, and superior long-term sealing.

➤ Biodentine
A bioactive dentin substitute with faster setting time and strong pulpal healing potential.

➤ Zinc Oxide–Eugenol (ZOE)
Traditional obturation material for primary teeth, but less favorable in cases requiring complete resorption.

➤ Iodoform-based Pastes (Vitapex/Metapex)
Preferred for pulpectomy due to their resorbability and antimicrobial action.
