The aim of the current study was carried to determine the relation of spacing, closed dentition, and occlusal relation with malocclusion in the primary dentition in children during deciduous dentition period among school children of Davangere.
A total of 945 school children all having deciduous teeth were included in the study. Informed consent for the child's participation is taken from the school principal. The dentition was examined under natural daylight, and the data was recorded. All the school children were screened for spaced and non-spaced dentition, molar and canine relationship.
The results concluded that most of the children showed spaced dentition (82.1%) when compared to non-spaced dentition (17.9%) with males shown more spaced dentition than compared to females. Among all children examined for molar and canine relation, flush terminal molar relation (65%) showed highest among all molar relation followed by mesial step (31%) and distal step (4%), and Class I canine relation (90%) was significant followed by Class II (6%) and Class III canine relation (4%). No significant difference was seen between right and left side.
The study concludes that determining the malocclusion and its correction at an early age helps in preventing a future complication in permanent dentition since stable primary occlusion leads to ideal occlusion in permanent dentition. Spacing, i.e., primate and physiologic space with the terminal molar relation in primary dentition indicates proper alignment of the permanent dentition.
本研究旨在确定达万盖雷学龄儿童乳牙列期乳牙间隙、牙列闭合及咬合关系与错牙合畸形之间的关系。
本研究共纳入945名均有乳牙的学龄儿童。已获得学校校长对儿童参与研究的知情同意。在自然日光下检查牙列,并记录数据。对所有学龄儿童进行牙列间隙和无间隙牙列、磨牙和尖牙关系的筛查。
结果表明,与无间隙牙列(17.)相比,大多数儿童表现出牙列间隙(82.1%),男性的牙列间隙比女性更多。在所有接受磨牙和尖牙关系检查的儿童中,平齐末端磨牙关系(65%)在所有磨牙关系中占比最高,其次是近中阶梯关系(31%)和远中阶梯关系(4%),I类尖牙关系(90%)占比显著,其次是II类(6%)和III类尖牙关系(4%)。左右两侧未见显著差异。
本研究得出结论,早期确定错牙合畸形及其矫治有助于预防恒牙列未来的并发症,因为稳定的乳牙咬合可导致恒牙列的理想咬合。乳牙列中的间隙,即灵长间隙和生理间隙以及末端磨牙关系,表明恒牙列排列正常。
