Direct pulp capping involves applying a medicament directly to an exposed dental pulp to preserve its vitality and involves indications such as a small exposure less than 4 mm with no observable hemorrhage or signs of infection. Indirect pulp capping involves removing gross caries and sealing the cavity with a biocompatible material to avoid exposing the pulp during caries removal when inflammation is minimal. Both procedures aim to maintain pulp vitality and healing through complete sealing and an aseptic technique, though failures can occur due to factors such as the degree of trauma, sealing ability, host resistance, presence of microorganisms, or aseptic technique failures.

3. DIRECT PULP CAPPING
Application of a medicament to exposed pulp to preserve the
vitality
1. Pinpoint – sound dentin – no hemorrhage - mild infl. – repaired
2. Pinpoint – sound dentin – drop of blood – mild infl.
3. Infected dentin – considerable – site far – doubtful
4. Profuse – greater infl. – very doubtful
5. Infl. Pus/fluid – destruction – not indicated

4. Indications: No H/O pain.
Exposure size < 4 mm
No observable hemorrhage
Clean uncontaminated field
Dentin at periphery is repairable
No pathologic changes
Contraindications: Severe toothache
Tooth mobility
Excess hemorrhage
Purulent discharge
Radiographic changes

5. Direct Pulp Capping

7. INDIRECT PULP CAPPING
Gross caries is removed and the cavity is sealed with a
biocompatible material
Indication: Pulp inflammation is minimal – complete removal
of caries would cause an exposure
Contraindication: Severe toothache
Tooth mobility
Purulent discharge
Radiographic changes

8. Indirect Pulp Capping

9. Objectives: Seal completely
Vitality.
No prolonged post-treatment
Pulp healing & tertiary dentin
No pathological changes.
Failures:
Degree of trauma
Sealing pressure
Low threshold of host resistance
Presence of microorganisms
Failure of an aseptic technique
