Traumatized immature teeth treated with 2 protocols of pulp revascularization.

Abstract Introduction Pulp revascularization may be considered a promising alternative for traumatized necrotic immature teeth. The aim of this study was to evaluate traumatized immature teeth treated with 2 protocols of pulp revascularization. Methods Twenty-three teeth of young patients (7–17 years old) with necrotic upper incisors caused by dental trauma were divided into 2 groups; one group was treated with triple antibiotic paste (metronidazole, ciprofloxacin, and minocycline) (TAP) ( n = 12), and the other was medicated with combination of calcium hydroxide and 2% chlorhexidine gel (CHP) ( n = 11). Patients were treated and followed up for a period from 9–19 months in 2 dental institutions for evaluation of clinical and radiographic data. Results Most of the teeth were affected by lateral luxation (47.8%). Clinical evaluation in group TAP showed significant reduction in spontaneous pain ( P = .01), pain on horizontal percussion ( P = .007), and pain on palpation ( P = .03), whereas group CHP showed significant reduction in pain on vertical percussion ( P = .03). Crown discoloration was observed significantly more in teeth of group TAP (83.3%) ( P P = .03). Similarly, the same findings were found for all teeth treated with CHP with exception of 1 tooth ( P = .21). Apical closure was significantly observed in both groups ( P Conclusions Revascularization outcomes for traumatized patients treated with the tested protocols presented similar clinical and radiographic data. However, TAP caused esthetic problem leading to tooth discoloration, which can be considered a disadvantage when compared with CHP.
