To determine whether there is a correlation between halitosis and mouth breathing in children.
Fifty-five children between 3 and 14 years of age were divided into two groups (nasal and mouth breathing) for the assessment of halitosis. A descriptive analysis was conducted on the degree of halitosis in each group. The chi-square test was used for comparison between groups, with a 5% level of significance.
There was a significantly greater number of boys with the mouth-breathing pattern than girls. A total of 23.6% of the participants had no mouth odor, 12.7% had mild odor, 12.7% had moderate odor and 50.9% had strong odor. There was a statistically significant association between halitosis and mouth breathing.
The occurrence of halitosis was high among the children evaluated, and there was a statistically significant association between halitosis and mouth breathing.
确定儿童口臭与口呼吸之间是否存在相关性。
将 55 名 3 至 14 岁的儿童分为两组（鼻呼吸和口呼吸），以评估口臭。对每组的口臭程度进行描述性分析。使用卡方检验进行组间比较，显著性水平为 5%。
口呼吸模式的男孩明显多于女孩。共有 23.6%的参与者无口臭，12.7%有轻度口臭，12.7%有中度口臭，50.9%有强烈口臭。口臭与口呼吸之间存在统计学显著关联。
在所评估的儿童中，口臭的发生率较高，且口臭与口呼吸之间存在统计学显著关联。
