- Rx chlorhexidine rinse 2x/day for 2 weeks
- Refer to medical professional for tetanus booster PRN
- @ 2 weeks, remove splint (unless bony fracture occurred) and evaluate clinically + radiographically for pulpal revascularization, infection, pulpal necrosis, and root resorption
- Initiate pulpal revascularization, apexification, or RCT as soon as definitive clinical and/or radiographic pathology presents
