Pulpal obliteration
Study Notes
- Root fracture: - Do not move loose teeth - X Root fracture: extrusion, luxation, force - Prognosis: 20% permanent pulp necrosis in coronal segment after successful endodontic treatment
- Necrotic pulp: - Difficult to treat - Inadequate strength - Believed pulp progenitor cells cannot survive infection
- Antibiotic mixture study: - Ciprofloxacin, metronidazole, minocycline - Penetrates through root dentin - Kills bacteria in deep layers of extracted tooth root dentine
- Regenerative Endodontics: - Evoked-bleeding step triggers accumulation of undifferentiated stem cells in canal space
- Immature tooth: - Main objective: continuation of alveolar growth and maturation - Antibiotic mixture has higher success rate than calcium hydroxide in vital pulp therapy
- Direct pulp capping: - Requirements for success: healthy pulp (trauma/iatrogenic) - Success rate: >90%, inflamed pulp (caries): <35%
- Deep caries lesions in adults: - Randomized clinical trials: stepwise excavation decreases risk of pulp exposure - Success rate: 74.1% for stepwise, 62.4% for complete excavation - Pooled pulp survival rate: 33.2% after 1.5 years for exposed pulps.
Exclusion criteria: - Prolonged pain, night sleep disturbance, no response to cold and electrical pulp testing, attachment loss > 5mm, apical radiolucency.
Root fracture treatment principles: - Do not attempt to move loose teeth - X Root fracture: extrusion, luxation, force - Prognosis: 20% permanent pulp necrosis in coronal segment after successful endodontic treatment.
Necrotic pulp: - Difficult to treat - Inadequate strength - Believed pulp progenitor cells cannot survive infection.
Antibiotic mixture study: - Ciprofloxacin, metronidazole, minocycline - Penetrates through root dentin - Kills bacteria in deep layers of extracted tooth root dentine.
Regenerative Endodontics: - Evoked-bleeding step triggers accumulation of undifferentiated stem cells in canal space - These cells might contribute to regeneration of pulpal tissues.
Immature tooth: - Main objective: continuation of alveolar growth and maturation - Antibiotic mixture has higher success rate than calcium hydroxide in vital pulp therapy.
