The aim of our study was to investigate the prevalence of temporomandibular dysfunction (TMD) during orthodontic treatment.
the study investigated all the patients receiving orthodontic treatment in the dentofacial orthopedic department in Casablanca in the course of the different stages of treatment over a 4-month period. We looked for a possible association between the presence of at least one sign of TMD, the Helkimo anamnesis index, the clinical Helkimo index and the following factors: age, gender, extractions, or not, of premolars, duration, type and stage of orthodontic treatment, molar and canine class, crowding, overjet, overbite and unilateral crossbite. Data were analysed using Epi-info 6.0.fr software. The analysis of the results was done using the Chi(2) test (P<0.05).
no statistically significant association could be established between TMD and the various factors under investigation with the exception of the association between gender and the Helkimo anamnesis index, stage of treatment and the Helkimo anamnesis index and the Angle molar class and the Helkimo clinical index.
我们研究的目的是调查正畸治疗期间颞下颌关节紊乱病（TMD）的患病率。
本研究调查了卡萨布兰卡口腔正畸科在4个月治疗期间不同阶段接受正畸治疗的所有患者。我们探寻了至少一种TMD体征的存在、赫尔基莫问诊指数、临床赫尔基莫指数与以下因素之间可能存在的关联：年龄、性别、是否拔除前磨牙、正畸治疗的持续时间、类型和阶段、磨牙和尖牙分类、牙列拥挤、覆盖、覆合和单侧反合。使用Epi-info 6.0.fr软件对数据进行分析。结果分析采用卡方检验（P<0.05）。
除了性别与赫尔基莫问诊指数、治疗阶段与赫尔基莫问诊指数以及安氏磨牙分类与赫尔基莫临床指数之间的关联外，TMD与所调查的各种因素之间未发现具有统计学意义的关联。
