The purpose of the research is to study the relationship between the certain pathogenic factors and the prevalence of functional disorders of TMJ in children and adolescents with mental development delay (MDD), in practically healthy persons of similar age living in children's homes and in a family.
The study was carried out using the method of observation, systematization, analysis and synthesis of the results obtained in the course of laboratory experiments.
Symptoms of TMD include decreased mandibular range of motion, muscle and joint pain, joint crepitus, and functional limitation or deviation of jaw opening. The mentioned symptoms were revealed in 40.1% of children and adolescents with MDD, less frequently in 32.62% of children and adolescents living in children's homes, and in 35.32% of practically healthy persons living in families and their rate increased with ageing. More often it was revealed in girls.
According to the results of the study, the authors found that children and adolescents with MDD, symptoms of TMJ dysfunctions occur more often and begin at an earlier age than in practically healthy ones.
本研究旨在探讨某些致病因素与智力发育迟缓（MDD）的儿童及青少年、生活在儿童福利院的同龄健康儿童以及家庭环境中的同龄健康儿童颞下颌关节功能紊乱患病率之间的关系。
本研究采用观察法、对实验室实验结果进行系统化、分析和综合的方法。
颞下颌关节紊乱病的症状包括下颌运动范围减小、肌肉和关节疼痛、关节弹响以及张口功能受限或偏斜。上述症状在40.1%的MDD儿童及青少年中出现，在生活在儿童福利院的儿童及青少年中出现的频率较低，为32.62%，在家庭环境中的健康儿童及青少年中出现的频率为35.32%，且该比例随年龄增长而增加。在女孩中更常出现。
根据研究结果，作者发现MDD儿童及青少年中，颞下颌关节功能障碍症状比健康儿童及青少年更常出现且发病年龄更早。
