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
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
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
