BACKGROUND/AIM: There are no data on the impacts on daily living of traumatic injuries to the permanent teeth. The aim of the present study was to assess the socio-dental impacts of untreated fractured anterior teeth in Brazilian schoolchildren.
A population-based matched case-control study was used and a 2 : 1 control-to-case ratio was adopted. The cases were 68 children 12-14 years old, having non-restored teeth, with fracture involving dentine. The controls were 136 children without any traumatic dental injury. They were matched by age, sex and socio-economic status. The Oral Impact on Daily Performances (OIDP) index was used to measure the impacts.
The response rate was 100%. Results of conditional logistic regression showed that children with fractured teeth were 20 times (95% CI = 2.2-45.6) more likely to report any impact on their daily living than children with no traumatic dental injury. These results remained statistically significant for the items of the OIDP separately, 'smiling' (P < 0.001), 'maintaining emotional state' (P < 0.001), 'eating' (P < 0.01), 'enjoying contact with people' (P < 0.01) and the overall OIDP (P < 0.001), after adjusting for confounding variables such as the Aesthetic Component of the Index of Orthodontic Treatment Need and DMFT index in a multiple conditional logistic regression.
Children with untreated dental fracture of permanent teeth had more impacts on their daily living than children without any traumatic injury.
背景/目的：目前尚无关于恒牙外伤对日常生活影响的数据。本研究旨在评估巴西学龄儿童未治疗的前牙骨折的社会口腔影响。
采用基于人群的匹配病例对照研究，病例与对照的比例为2:1。病例为68名12 - 14岁的儿童，其牙齿未修复，骨折累及牙本质。对照为136名无任何牙外伤的儿童。他们按年龄、性别和社会经济地位进行匹配。使用日常口腔功能影响（OIDP）指数来衡量影响。
应答率为100%。条件逻辑回归结果显示，与无牙外伤的儿童相比，牙齿骨折的儿童报告日常生活受到任何影响的可能性高出20倍（95%可信区间 = 2.2 - 45.6）。在多条件逻辑回归中对诸如正畸治疗需求指数的美学成分和DMFT指数等混杂变量进行调整后，对于OIDP的各个项目，“微笑”（P < 0.001）、“维持情绪状态”（P < 0.001）、“进食”（P < 0.01）、“享受与人接触”（P < 0.01）以及总体OIDP（P < 0.001），这些结果仍具有统计学意义。
恒牙未治疗的牙骨折儿童比无任何外伤的儿童对日常生活的影响更大。
