由于气候变化,畸形的患病率从一代到另一代不断增加,土壤,大气,和水污染。所有这些方面对营养方案具有不利的后果。因此,营养,连同其他致病因素,有助于整个生物体的体细胞发育的复杂变化,含蓄地,头端。该研究小组包括来自瓦尔西萨县随机选择的学校的4147名儿童,罗马尼亚。这项研究的目的是确定瓦尔西萨县学童咬合不正的患病率,罗马尼亚,根据三种主要类型的错牙合(根据角度的分类),年龄组(6至10岁和11至14岁),性别(男性和女性),和原产地(农村和城市)。对于I类角度错合,我们记录的患病率最高(占患有错牙合的学童总数的48.78%),其次是AngleII类错牙合(占错牙合学童总数的45.85%),对于AngleIII类错牙合,我们发现患病率最低(占患有错牙合的学童总数的5.37%)。根据性别,我们发现女性患病率最高(占女性受试者总数的29.90%),而在男性中,我们记录的患病率占男性受试者总数的27.70%.关于原产地,城市地区的咬合畸形患病率较高(29.16%)。研究亚组包括从研究组的受试者总数中随机选择的140名儿童。他们被纳入了更高级的研究。目的是发现咬合不正的存在与各种口腔变量之间的潜在关联。分类变量表示为数值和百分比,用关联或同质性的卡方检验评估它们的关联,或者费希尔精确检验。将获得的数据合并到二项逻辑回归模型中,以评估与以下变量相关的发生错合的可能性:有缺陷的发声,磨牙症,刷牙的频率,甲癣,口腔呼吸,婴儿吞咽,在上颌骨之间放置物体,拇指吸吮,和唾液方面。它还旨在将获得的结果与专业文献中的类似结果进行比较。
Malocclusions have a continuously increasing prevalence from one generation to another as a result of climate change, soil, atmosphere, and water pollution. All of these aspects have unfavorable consequences for the nutritional scheme. Thus, nutrition, together with other etiopathogenic factors, contributes to complex alterations in the somatic development of the entire organism and, implicitly, of the cephalic extremity. The study group included 4147 children from randomly selected schools from Vâlcea County, Romania. The aim of this study is to determine the prevalence of malocclusions in schoolchildren in Vâlcea County, Romania, according to the three main classes of malocclusions (according to Angle\'s classification), age groups (from 6 to 10 years old and from 11 to 14 years old), gender (male and female), and place of origin (rural and urban). For Angle class I malocclusions, we recorded the highest prevalence (48.78% of the total number of schoolchildren with malocclusions), followed by Angle class II malocclusions (45.85% of the total number of schoolchildren with malocclusions), and for Angle class III malocclusions we found the lowest prevalence (5.37% of the total number of schoolchildren with malocclusions). According to gender, we found the highest prevalence in the female gender (29.90% of the total number of female subjects), while in the male gender, we recorded a prevalence of 27.70% of the total number of male subjects. Regarding the place of origin, there is a higher prevalence of malocclusions in urban areas (29.16%). The study subgroup included 140 children randomly selected from the total number of subjects in the study group. They were included in a more advanced study. The aim is to find potential associations between the presence of malocclusions and various oral variables. Categorical variables were expressed as numerical values and percentages, and their association was evaluated with either the Chi-square test of association or homogeneity, or the Fisher Exact test. The acquired data were incorporated into a binomial logistic regression model to assess the likelihood of developing malocclusions in relation to the following variables: defective phonation, bruxism, frequency of teeth brushing, onychophagia, oral respiration, infantile deglutition, placing objects between the maxillaries, thumb sucking, and salivary aspects. It is also aimed at comparing the results obtained with similar ones from the specialized literature.
