To investigate the etiologic factors, effect of age and gender on dental trauma, and to evaluate the performance of composite resin on the fractured crown of permanent anterior teeth.
Over a 2-year period, 73 permanent teeth from 51 patients with dental trauma were treated with direct composite resin restoration. Informed consent and standardized trauma forms were completed by the patient; teeth were restored with a submicron hybrid composite resin (Spectrum TPH) and respective adhesive system (Prime&Bond NT). Sixty-nine teeth were directly restored without fiber posts, while four were treated with fiber posts. Two experienced clinicians, besides the operator, evaluated each restoration at 6-, 12-, and 24-month follow-ups according to US Public Health Service (USPHS) criteria for the following characteristics: anatomical form, marginal adaptation, color match, marginal discoloration, surface roughness, and caries. Data were analyzed using the Wilcoxon Signed Rank, Kruskal-Wallis, Mann-Whitney U, and Siegel and Castellan tests.
A total of 73 traumatized teeth in 51 patients aged from 14 to 64 years (mean age 25.47 ± 14.058 years) were assessed according to the Ellis classification and restored over a 2-year period. Crown fractures were more common in the maxilla (84.9%) and caused by falls (58.8%). At the end of 24 months, a total of ten restorations were lost. The survival rate after 24 months was 82.14%. There were statistically significant differences in marginal adaptation between the 6-, 12-, and 24-month follow-ups. Although changes in marginal discoloration over time were not significant (p = 0.194), changes in color match were significant (p = 0.029).
Within the limitations of this study, direct composite restorations were accepted as clinically satisfactory.
调查牙外伤的病因、年龄和性别影响，并评估复合树脂对恒前牙折裂冠的修复效果。
在两年期间，51 名牙外伤患者的 73 颗恒牙接受了直接复合树脂修复。患者完成了知情同意书和标准化创伤表格；牙齿用亚微米混合复合树脂（Spectrum TPH）和相应的粘接系统（Prime&Bond NT）进行修复。69 颗牙未经纤维桩直接修复，4 颗牙经纤维桩治疗。除操作者外，还有两位经验丰富的临床医生在 6、12 和 24 个月的随访时根据美国公共卫生服务（USPHS）标准评估每个修复体的以下特征：解剖形态、边缘适应性、颜色匹配、边缘变色、表面粗糙度和龋齿。使用 Wilcoxon 符号秩和检验、Kruskal-Wallis 检验、Mann-Whitney U 检验和 Siegel 和 Castellan 检验对数据进行分析。
根据 Ellis 分类，51 名 14 至 64 岁（平均 25.47±14.058 岁）患者的 73 颗外伤牙在两年期间接受了评估，并进行了修复。上颌（84.9%）和由跌倒引起的冠折更为常见（58.8%）。在 24 个月结束时，共有 10 个修复体丢失。24 个月后的生存率为 82.14%。在 6、12 和 24 个月的随访中，边缘适应性存在统计学显著差异。虽然边缘变色随时间的变化没有统计学意义（p=0.194），但颜色匹配的变化具有统计学意义（p=0.029）。
在本研究的限制范围内，直接复合树脂修复被认为具有临床满意度。
