This study aimed to evaluate the treatment outcomes of permanent teeth with uncomplicated and complicated crown fractures and to investigate potential factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>This retrospective study included patients who experienced crown fractures in permanent teeth from 2018 to 2021 with at least 12\u2009months of follow\u2010up. All complicated crown fractured teeth were treated with pulpotomy, while for teeth with uncomplicated crown fractures, three treatments (restoration, indirect pulp capping, or pulpotomy) were employed. The chi\u2010square test was used to compare the prognosis of teeth with uncomplicated and complicated crown fractures. Potential factors associated with pulp survival including gender, interval, root development, enamel infraction, mobility, concomitant luxation injury, treatment, and coronal restoration were identified via Cox regression analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 307 teeth from 220 children (average age\u2009=\u20099.3\u2009\u00b1\u20091.4\u2009years; age range, 6\u201314\u2009years) with a median follow\u2010up of 23\u2009months were included, and 82.1% of all teeth had immature roots. Complicated crown fractured teeth (93.6%, 102\/109) had a significantly higher success rate compared with uncomplicated crown fractured teeth (85.4%, 169\/198) (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). Pulpotomy (96.9%) had the highest success rate of all treatments for uncomplicated crown fractures, followed by only restoration (85.0%) and indirect pulp capping (76.9%). The success rate of teeth that received pulpotomy was significantly higher than those treated by indirect pulp capping (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05). In uncomplicated crown fractures, teeth with Class II mobility were more vulnerable to failure than teeth without abnormal mobility (HR\u2009=\u200934.83; 95% CI, 9.59\u2013126.56; <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05); teeth that received pulpotomy were less prone to failure than teeth that received indirect pulp capping (HR\u2009=\u200913.53; 95% CI, 1.58\u2013115.72; <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Crown fractures treated with conservative pulp treatments had a relatively highly favorable prognosis. The prognosis of uncomplicated crown fractured teeth was impacted by the severity of periodontal injury and treatment strategies. Accurate diagnosis and identification of micro\u2010exposures are important.
