To evaluate the relationship between type and duration of breastfeeding and the development of malocclusion in primary dentition.
A cross-sectional observational study was conducted with children of both sexes, aged 30 to 48 months, who attended to a dental program for maternal and child care. The mothers completed a questionnaire about the form (exclusive breast-feeding or not) and duration of breastfeeding, their children's non-nutritive sucking habits, and their sociodemographic information. The clinical examination was done by a calibrated examiner in the knee-to-knee position and under indirect light to evaluate the primary occlusion. Pearson's chi-square test or Fisher's exact test and Poisson regression were performed for statistical analysis.
Over 45 percent of 252 children who were evaluated had malocclusion, such as anterior open bite (13.6 percent), posterior crossbite (3.6 percent), anterior crossbite (2.8 percent), midline shift (21.5 percent), overbite (19.8 percent), and overjet (32.9 percent). Children who were exclusively breastfed for less than six months had a 50 percent higher prevalence of anterior open bite ( =0.009) compared to those who had exclusive breastfeeding for more than six months.
Exclusive breastfeeding for less than six months was associated with anterior open bite. The other malocclusion types were not associated with the time and type of feeding the children received in the early phase of the primary dentition.
评估母乳喂养的类型和持续时间与乳牙列错牙合畸形发展之间的关系。
对年龄在30至48个月的参加母婴保健牙科项目的男女儿童进行了一项横断面观察性研究。母亲们填写了一份关于母乳喂养形式（是否纯母乳喂养）和持续时间、孩子的非营养性吮吸习惯以及她们的社会人口学信息的问卷。由一名经过校准的检查者在面对面的位置和间接光线下进行临床检查，以评估乳牙列咬合情况。采用Pearson卡方检验或Fisher精确检验以及泊松回归进行统计分析。
在接受评估的252名儿童中，超过45%患有错牙合畸形，如前牙开牙合（13.6%）、后牙反牙合（3.6%）、前牙反牙合（2.8%）、中线偏移（21.5%）、覆牙合（19.8%）和覆盖（32.9%）。与纯母乳喂养超过6个月的儿童相比，纯母乳喂养少于6个月的儿童前牙开牙合的患病率高50%（P = 0.009）。
纯母乳喂养少于6个月与前牙开牙合有关。其他错牙合畸形类型与乳牙列早期儿童接受的喂养时间和类型无关。
