Dental Radiography and Imaging

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 < .002). On radiographic exam, periapical repair was found in all TAP-treated teeth (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 < .05). Increase in root length was demonstrated in 5 teeth (41.7%) and 3 teeth (27.3%) of groups TAP and CHP, respectively. Thickening of lateral dentinal walls was observed in 5 teeth of each group. 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.
