GAO Yunyun,HUANG Jianjing,XIE Yalun.. Retrospective study of the pulp prognosis and influence factors of dentin-fractured teeth[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2016, 46(6): 438-441.
Abstract：Objective: The dental pulp prognosis and influential factors of dentin-fractured permanent teeth were analyzed retrospectively. Methods: Retrospective analysis was performed on the dentin-fractured patients treated in the Department of Stomatology of our hospital during the period from February 2012 to March 2014. The associative information of patients such as sex, age, the treatment time and method, the teeth-root development, the extent of fracture close to dental pulp, the tooth mobility and treatment pain were recorded in detail. The therapeutic effect, prognosis of dental pulp and the factors influencing the prognosis of dental pulp were analyzed by retrospective analysis. Results: Totally 305 patients who met the inclusion criteria and 325 diseased teeth were collected. Among all the dentin-fractured teeth, pulp necrosis occurred in 77 teeth (23.7%) and pulp survived or calcification occurred in 248 teeth (76.3%). The success rate of indirect pulp capping on the dentin-fractured teeth was 76.3% and had a certain statistical significance. The extent of fracture close to dental pulp and the percussion pain of treatment were highly significantly correlated to the pulp necrosis rate (P<0.05), contrarily, there is no significant correlation between the pulp necrosis rate and the factors such as age and sex of patients (P>0.05). Conclusion: The indirect pulp capping on the dentin-fractured teeth can get a higher success rate. The extent of fracture close to dental pulp and the percussion pain of treatment can be the important factors to judge the prognosis of dental pulp.
