To assess the prevalence of malocclusion and to determine the different occlusal characteristics in primary dentition of 4 to 6 years old children in India.
The target population comprised 4 to 6 years old children attending different nursery, kindergarten and primary schools of Bagalkot city. Stratified cluster random sampling procedure was executed to collect the representative sample. Each subject was assessed for various occlusal characteristics.
Occlusal characteristic found were flush terminal plane (52.5%), class I canine relationship (84%), maxillary developmental spaces (35.4%), primate spaces in maxilla (47.6%), mandibular crowding (4.6%), mandibular midline shift (5.6%), anterior multiple tooth crossbite (1.3%), scissors bite (0.6%), anterior open bite (1%), over bite of 0-2 mm (81.6%) and overjet of 0-2 mm (84.5%). The age wise difference for the occlusal characteristics was statistically significant.
The data revealed that most of the children had malocclusion. This highlights the importance of identifying children who are in need of orthodontic treatment for dental health or aesthetic reasons.
评估印度4至6岁儿童乳牙列错牙合畸形的患病率,并确定其不同的咬合特征。
目标人群为就读于巴加尔科特市不同幼儿园、学前班和小学的4至6岁儿童。采用分层整群随机抽样程序收集代表性样本。对每个受试者的各种咬合特征进行评估。
发现的咬合特征有平齐终末平面(52.5%)、I类犬牙关系(84%)、上颌发育间隙(35.4%)、上颌灵长间隙(47.6%)、下颌拥挤(4.6%)、下颌中线偏移(5.6%)、前牙多数牙反牙合(1.3%)、剪刀牙合(0.6%)、前牙开牙合(1%)、覆牙合0 - 2毫米(81.6%)和覆盖0 - 2毫米(84.5%)。咬合特征的年龄差异具有统计学意义。
数据显示大多数儿童存在错牙合畸形。这凸显了出于牙齿健康或美观原因识别需要正畸治疗儿童的重要性。
