Study Notes
Pulp Therapy in Primary Teeth: Indirect Pulp Capping, Direct Pulp Capping, and Vital Pulpotomy
- Factors to consider for pulp therapy: age of patient, history of pain, clinical examination, and radiographic examination
- Pulp therapy options for primary teeth: indirect pulp capping, direct pulp capping, pulpotomy, partial pulpectomy, and pulpectomy
- Indirect pulp capping involves leaving softened dentine in deep carious lesions to avoid pulp exposure and covering it with materials like calcium hydroxide or MTA
- Technique for indirect pulp capping: clearing caries, gentle excavation, and covering with material followed by glass ionomer and composite resin
- Direct pulp capping is not recommended in primary teeth due to inflamed pulp prior to exposure, leading to poor success rates
- Vital pulpotomy is the removal of coronal pulp tissue till the orifices, capping radicular pulp tissues, and placing a coronal restoration
- Indications and technique for vital pulpotomy: wide pulp exposure, slight controlled bleeding, normal pulp and radiographic signs, and specific steps for the procedure
- Pulpotomy techniques are based on devitalization, involving the use of Formcresol as a fixative and antimicrobial agent
- Composition of Buckly’s formocresol: 19% formalin, 35% cresol, glycerin, and distilled water
- Concerns over the use of formocresol and other medicaments due to their potential carcinogenic effects
- Excessive uncontrollable bleeding during pulp therapy indicates an unfavorable condition, leading to non-vital pulpectomy or extraction
- Careful diagnosis is crucial for determining the level of therapy based on the extent of injury or disease in primary teeth
