Estimating orthodontic treatment need in the permanent dentition using information from the deciduous-dentition malocclusion may assist in defining the time for appropriate orthodontic intervention. Our objective was to investigate whether malocclusion in the deciduous teeth predicts orthodontic treatment need in the permanent dentition.
Two oral health studies nested in a birth cohort were carried out at ages 6 (n = 359) and 12 (n = 339) years. Open bite, crossbite, and canine malocclusion were assessed in the deciduous teeth. Orthodontic treatment need was determined in the permanent dentition using the dental esthetic index. Prevalence ratios were estimated using 2 dental esthetic index cutoff points: highly desirable/mandatory orthodontic treatment and only mandatory orthodontic treatment. We tested all combinations of the deciduous malocclusion and the outcomes, controlling for confounders.
Children with only open bite and those with concurrent open bite and canine malocclusion were more likely to have either highly desirable/mandatory orthodontic treatment or only mandatory orthodontic treatment needs by age 12. The combination of crossbite and open bite in the deciduous teeth was associated with the highest risk of need for mandatory orthodontic treatment.
Malocclusion in the deciduous teeth is a risk factor for orthodontic treatment need in the permanent dentition. Children with malocclusion at a young age should be monitored regularly, and caregivers may be able to better prepare for possible orthodontic treatment.
利用乳牙列错颌畸形的信息来估计恒牙列的正畸治疗需求，可能有助于确定适当正畸干预的时机。我们的目的是调查乳牙列错颌畸形是否能预测恒牙列的正畸治疗需求。
在一个出生队列中进行了两项口腔健康研究，分别在6岁（n = 359）和12岁（n = 339）时进行。评估乳牙列中的开颌、反颌和犬牙错颌情况。使用牙齿美观指数确定恒牙列的正畸治疗需求。使用两个牙齿美观指数切点估计患病率比：非常理想/强制性正畸治疗和仅强制性正畸治疗。我们测试了乳牙列错颌畸形与结果的所有组合，并对混杂因素进行了控制。
仅患有开颌的儿童以及同时患有开颌和犬牙错颌的儿童，到12岁时更有可能需要进行非常理想/强制性正畸治疗或仅强制性正畸治疗。乳牙列中反颌和开颌的组合与强制性正畸治疗需求的风险最高相关。
乳牙列错颌畸形是恒牙列正畸治疗需求的一个风险因素。年幼时有错颌畸形的儿童应定期监测，照顾者可能能够更好地为可能的正畸治疗做好准备。
