Given the fact that bruxism is a prevalent oral habit among children and a potential destructor of oral tissues, the present study aimed to investigate the relationship between intestinal parasitic infections and bruxism among kindergarten children.
Questionnaires were administered among parents of kindergarten children in Isfahan to select 50 children identified by their parents to have the habit of bruxism and 50 without the habit as control group. Informed consent was obtained prior to the investigation. Parents were delivered sampling instruments with proper instructions to collect stool samples from both groups for parasitological tests. The diagnostic parasitological tests involved the direct stool smear, formol-ether concentration, and Scotch tape tests. Comparison for the frequency distribution of intestinal parasitic infections between the two groups was performed using the chi-square test (α = 0.05).
Parasitic infections were observed in 19 (11/50 cases and 8/50 controls) children. A statistically significant relationship was observed between infection with pathogenic parasites and bruxism (P < 0.05).
Our findings suggest that pathogenic parasites may serve as the cause of initiation of bruxism habits among children.
鉴于磨牙症是儿童中普遍存在的口腔习惯且是口腔组织的潜在破坏因素，本研究旨在调查幼儿园儿童肠道寄生虫感染与磨牙症之间的关系。
对伊斯法罕幼儿园儿童的家长进行问卷调查，以挑选出50名被家长认定有磨牙习惯的儿童，并挑选50名无此习惯的儿童作为对照组。在调查前获得了知情同意。向家长发放采样工具并给予适当指导，以便从两组儿童中采集粪便样本进行寄生虫学检测。寄生虫学诊断检测包括直接粪便涂片、甲醛乙醚浓缩法和透明胶带法检测。使用卡方检验（α = 0.05）对两组肠道寄生虫感染的频率分布进行比较。
在19名儿童（11名病例组儿童和8名对照组儿童）中观察到寄生虫感染。在感染致病性寄生虫与磨牙症之间观察到具有统计学意义的关系（P < 0.05）。
我们的研究结果表明，致病性寄生虫可能是儿童磨牙症习惯起始的原因。
