Study on the effect of traumatic coronary pulp exposure time and initial percussion pain on prognosis in young permanent teeth
Objective To investigate the independent risk factors of poor prognosis in young patients with coronal exposure due to trauma after live pulp amputation or direct pulp capping,and to evaluate the influence of pulp exposure time and initial percussion pain on pulp prognosis.Method The clinical data of 219 cases of young permanent tooth crown exposure caused by trauma admitted to the Affiliated Hospital of Chengde Medical University from March 2018 to September 2020 were retrospectively analyzed.Patients were initially treated with either live pulpotomy or direct pulpotomy and were followed up 1 year after surgery.Univariate analysis and multivariate logistic regression were used to analyze the independent risk factors for poor dental pulp prognosis,and the predictive value of these independent risk factors for poor dental pulp prognosis was analyzed by the receiver operating characteristics(ROC)curve.Result After 1 year follow-up,there were 20 cases of treatment failure and 199 cases of successful treatment.The total success rate of living pulp amputation was 90.87%.Single factor results showed that apical development,pulp exposure time and initial knock pain were associated with poor pulp prognosis(P＜0.05),while age,sex,injury cause,injured tooth location,temperature test results,difference of pulp electrical activity,diameter of pulp exposure hole,flexibility of affected tooth and treatment plan were not associated with poor pulp prognosis(P＞0.05).Multivariate logistic regression analysis showed that percussion pain at first diagnosis(+++)was an independent risk factor for poor pulp prognosis(P＜0.05).ROC curve analysis results showed that the area under the curve of initial percussion pain(+++)predicting poor pulp prognosis was 0.860,sensitivity was 0.832,specificity was 0.865.Conclusion Initial percussion pain(+++)is an independent risk factor for poor prognosis in young permanent teeth with traumatic crown fracture and exposed pulp,and has a high predictive value.Pulp exposure time was not significantly related to pulp prognosis.
