To evaluate the association of breastfeeding duration, pacifier use and nasal air flow with occlusal disorders among children.
This cross-sectional observational study included 138 children aged 4 and 5 years selected in all the daycare centers of the city of Campo Limpo Paulista, Brazil. Questionnaires were applied to mothers to identify total duration of exclusive breastfeeding and non-nutritive sucking. The independent variables were: Sucking (pacifier, bottle, finger), breastfeeding duration and nasal air flow. The dependent variables were: Open bite, crossbite, overjet, overbite, diastema and maxillary deficiency. Frequency distribution calculations were performed, a chi-square test, the Fisher exact test and, after that, stepwise logistic regression were used for statistical analysis, and the level of significance was set at 5%.
The use of a pacifier was the most deleterious factor and increased chances of having open bite in 33.3 times, marked overjet in 2.77 times and posterior crossbite in 5.26 times.
There was a significant association between non-nutritive sucking, particularly the use of a pacifier, and occlusal disorders. These findings are important to plan the treatment of preschoolers.
评估儿童母乳喂养持续时间、使用安抚奶嘴及鼻气流与咬合紊乱之间的关联。
这项横断面观察性研究纳入了巴西坎波林波保利斯塔市所有日托中心选取的138名4岁和5岁儿童。向母亲们发放问卷，以确定纯母乳喂养的总时长和非营养性吸吮情况。自变量为：吸吮方式（安抚奶嘴、奶瓶、手指）、母乳喂养持续时间和鼻气流。因变量为：开 、反 、覆盖、覆 、牙间隙和上颌骨发育不全。进行了频率分布计算、卡方检验、费舍尔精确检验，之后采用逐步逻辑回归进行统计分析，显著性水平设定为5%。
使用安抚奶嘴是最有害的因素，出现开 的几率增加33.3倍，明显覆盖增加2.77倍，后牙反 增加5.26倍。
非营养性吸吮，尤其是使用安抚奶嘴，与咬合紊乱之间存在显著关联。这些发现对于规划学龄前儿童的治疗很重要。
