This study was carried out to determine the prevalence of temporomandibular joint (TMJ) dysfunction in mixed and permanent dentition and to evaluate the sex distribution in Turkish children. One hundred and eighty-two children with mixed dentition and 212 with permanent dentition were selected for the study, which used a questionnaire and clinical examination. Children with one or more signs (TMJ sounds, TMJ tenderness, muscle tenderness, restricted mouth opening) and/or symptoms (TMJ pain during mastication and mouth opening, restriction of the jaw opening and TMJ sounds) met the criterion of TMJ dysfunction. The total prevalence of signs and symptoms of TMJ dysfunction in the studied population was 68% (68% in girls and 68% in boys) in mixed dentition and 58% (61% in girls and 56% in boys) in permanent dentition. The Z-test and analysis of variance (ANOVA) were used for statistical analysis of the difference between the results. The total prevalence of signs and symptoms of TMJ dysfunction in mixed dentition was found to be higher than in permanent dentition (P < 0.05). No statistically significant difference was found in the total prevalence of TMJ dysfunction between girls and boys.
本研究旨在确定混合牙列和恒牙列中颞下颌关节（TMJ）功能紊乱的患病率，并评估土耳其儿童中的性别分布情况。本研究选取了182名混合牙列儿童和212名恒牙列儿童，采用问卷调查和临床检查的方法。有一项或多项体征（TMJ弹响、TMJ压痛、肌肉压痛、张口受限）和/或症状（咀嚼和张口时TMJ疼痛、下颌开口受限和TMJ弹响）的儿童符合TMJ功能紊乱的标准。在研究人群中，混合牙列中TMJ功能紊乱体征和症状的总患病率为68%（女孩为68%，男孩为68%），恒牙列中为58%（女孩为61%，男孩为56%）。采用Z检验和方差分析（ANOVA）对结果差异进行统计学分析。发现混合牙列中TMJ功能紊乱体征和症状的总患病率高于恒牙列（P < 0.05）。女孩和男孩之间TMJ功能紊乱的总患病率没有统计学上的显著差异。
