Bruxism is the habit of clenching or grinding one's teeth in non-functional activities and affects both children and adults alike. Respiratory problems, such as asthma and upper airway infections, are reported to be the etiological factors of bruxism.
The aim of the present study was to determine whether there is an association between respiratory problems and dental caries in children who exhibit the habit of bruxism.
An observational cross-sectional study was carried out.
Patient histories were taken and clinical exams were performed on 90 children for selection and allocation to one of two groups. For the determination of bruxism, a questionnaire was administered to parents/guardians and an oral clinical exam was performed based on the criteria of the American Academy of Sleep Medicine. Thirty-three male and female children between 4 and 7 years of age participated in the study - 14 children with bruxism and 19 children without bruxism.
The data were statistically analyzed using the chi-square test, with level of significance set at 5% (P < 0.05).
Mean age of the participants was 5.73 years. The male gender accounted for 45.5% (n = 15) of the sample and the female gender accounted for 54.5% (n = 18). A statistically significant association was found between respiratory problems and dental caries among the children with bruxism. Seventy-seven percent of the children with bruxism had caries and 62.5% the children with respiratory problems exhibited the habit of bruxism.
There seems to be an association between bruxism, respiratory problems, and dental caries in children.
磨牙症是指在非功能性活动中咬紧或磨牙的习惯，儿童和成人都会受到影响。据报道，呼吸系统问题，如哮喘和上呼吸道感染，是磨牙症的病因。
本研究的目的是确定有磨牙习惯的儿童的呼吸系统问题与龋齿之间是否存在关联。
进行了一项观察性横断面研究。
收集了90名儿童的病史并进行了临床检查，以进行选择并分配到两个组中的一组。为了确定磨牙症，向父母/监护人发放了问卷，并根据美国睡眠医学学会的标准进行了口腔临床检查。33名4至7岁的男女儿童参与了研究——14名有磨牙症的儿童和19名无磨牙症的儿童。
使用卡方检验对数据进行统计分析，显著性水平设定为5%（P < 0.05）。
参与者的平均年龄为5.73岁。男性占样本的45.5%（n = 15），女性占54.5%（n = 18）。在有磨牙症的儿童中，呼吸系统问题与龋齿之间存在统计学上的显著关联。77%有磨牙症的儿童患有龋齿，62.5%有呼吸系统问题的儿童有磨牙习惯。
儿童的磨牙症、呼吸系统问题和龋齿之间似乎存在关联。
