Preterm children may not be prepared for extra-uterine life and thus need neonatal intensive care, such as artificial ventilation through orotracheal intubation. Oral tissue development changes as a result of the use of an orotracheal tube and its mechanical influence in preterm neonates has not been intensively studied. The purpose of the present study was to determine the association of orotracheal intubation with incidence of oral alterations in preterm infants.
A retrospective cohort of 117 subjects who were born during the period 2002-2003 in Brazil were evaluated and the data were analysed using the Fisher and Mann-Whitney exact tests. A 95% confidence interval was calculated for observed oral conditions.
The cohort revealed that the most frequent oral conditions included anterior crossbite, superior alveolar contour and palatal deformation.
The association between the intubated-infant group and the non-intubated-infant group suggested that mechanical trauma had an influence on the oral structure development.
早产儿可能未做好宫外生活的准备，因此需要新生儿重症监护，如通过口气管插管进行人工通气。口气管插管的使用会导致口腔组织发育发生变化，其对早产儿的机械影响尚未得到深入研究。本研究的目的是确定口气管插管与早产儿口腔改变发生率之间的关联。
对2002年至2003年期间在巴西出生的117名受试者进行回顾性队列研究，并使用Fisher检验和Mann-Whitney精确检验对数据进行分析。计算观察到的口腔状况的95%置信区间。
该队列研究表明，最常见的口腔状况包括前牙反合、上牙槽轮廓和腭部变形。
插管婴儿组和未插管婴儿组之间的关联表明，机械创伤对口腔结构发育有影响。
