Traumatized immature teeth treated with 2 protocols of pulp revascularization

Area of Science:

• Endodontics
• Pediatric Dentistry
• Dental Traumatology

Background:

• Pulp revascularization is a viable treatment for immature necrotic teeth following trauma.
• Evaluating different revascularization protocols is crucial for optimizing outcomes.

Purpose of the Study:

• To compare the clinical and radiographic effectiveness of two pulp revascularization protocols in traumatized immature teeth.
• To assess the outcomes of triple antibiotic paste (TAP) versus calcium hydroxide and chlorhexidine gel (CHP).

Main Methods:

• Twenty-three necrotic immature incisors in patients aged 7-17 were treated with either TAP (n=12) or CHP (n=11).
• Clinical and radiographic evaluations were performed over a 9-19 month follow-up period.

Main Results:

• Both TAP and CHP groups showed significant pain reduction and radiographic signs of healing, including periapical repair and apical closure.
• TAP treatment resulted in significantly higher rates of crown discoloration (83.3%) compared to CHP.
• Root lengthening and dentinal wall thickening were observed in both groups, with slightly higher incidence in the TAP group.

Conclusions:

• Pulp revascularization with TAP and CHP yields comparable clinical and radiographic results for traumatized immature teeth.
• Triple antibiotic paste (TAP) is associated with a significant esthetic disadvantage due to tooth discoloration.
• Calcium hydroxide and chlorhexidine gel (CHP) may be preferred when esthetics are a primary concern.
