ABSTRACT
OBJECTIVE:
To analyze the clinical and radiographic effectiveness of a calcium silicate-based bioactive ceramic iRoot BP Plus® pulpotomy of immature permanent teeth with complicated crown fracture and to evaluate the factors influencing its long-term success rate.METHODS:
The digital medical records of patients under 13 years old who had undergone iRoot BP Plus® pulpotomy in the Department of Oral Emergency or the First Clinical Division, Peking University School and Hospital of Stomatology from March 2017 to September 2022 due to complicated crown fracture of anterior teeth, and had taken at least one post-operation apical radiograph were reviewed. The clinical and radiographic information at the initial examination and follow-up period were obtained, including crown color, mobility, percussion, cold test (partial pulpotomy teeth), dental restoration, fistula, swelling or inflammation of the gingival tissue, the formation of apical foramen, pathologic radiolucency and calcification of pulp chamber or root canal obliteration. Data were tested by Fisher exact test and a multiple comparison.RESULTS:
In the study, 64 patients including 37 males (57.8%) and 27 females (42.2%) with a mean age of 9.1 years ere finally enrolled. The total number of permanent teeth that received pulpotomy was 75, and the average follow-up time was 19.3 months. The success rate was 93.1% with the time interval between dental injury and treatment in 24 h, while the success rate dropped to 88.2% with the time intervals beyond 24 h. The time intervals did not significantly affect the pulp survival rate (P=0.61) after pulpotomy (partial or coronal). The success rate 6 months after pulpotomy was 96. 0%, and one-year success rate was 94. 7%. A total of 23 cases were reviewed for more than 2 years after pulpotomy, and 6 cases failed. The mobility had no significant effect on the success rate (P=0.28). Pulp chamber calcification and pulp canal obli-teration were not observed in all the post-operative radiographs.CONCLUSION:
The one year clinical and radiographic success rates obtained in this study indicate that iRoot BP Plus® is an appropriate pulp capping material option for pulpotomy treatment of complicated crown fracture in immature permanent teeth without displacement injuries. This technique has broad promotional value.Palavras-chave
