The goal of this study was to determine the frequency of early primary tooth loss among school children in and around Melmaruvathur, Tamil Nadu, India.
A cross-sectional study involving all the children aged between 5 and 9 years in and around Melmaruvathur, Tamil Nadu, India, from January 2022 to July 2022 was conducted. A total of 20 government schools were approached for participation in the study, study population consisted of 800 government school children (358 boys and 442 girls). All clinical assessments were done in the natural light by an experienced examiner. Age and missing teeth were among the data gathered.
The findings revealed that 20.8% of the sample had lost their primary teeth before the age of 6 ( > 0.05), although no gender differences were seen, males (12.6%) were more commonly affected than females (8.2%). The mandibular arch (61.8%) was more commonly affected than the maxillary arch (38.2%). In accordance with the frequency of early loss of teeth relative to tooth type, the molars (98.2%) were the most commonly prematurely lost teeth followed by the incisors (1.5%) and the cuspids (0.3%). The left lower primary first molars (42.3%) were the most often missing teeth, and the frequency was highest in 8-year-old children (38.9%).
It was shown that lower primary molars were the most often missing teeth in the current investigation, and that early loss was highly prevalent.
Early loss of primary teeth leads to lots of malocclusion problems mainly arch length discrepancies are seen. Early detection and management of the space problems associated with the early loss of primary teeth would help in reducing malocclusion problems.
本研究旨在确定印度泰米尔纳德邦 Melmaruvathur 及其周边地区学龄儿童早期乳牙丧失的频率。
本研究为横断面研究,于 2022 年 1 月至 7 月期间,在印度泰米尔纳德邦 Melmaruvathur 及其周边地区对所有 5 至 9 岁的儿童进行了研究。共有 20 所政府学校参与了这项研究,研究人群由 800 名政府在校儿童组成(男 358 名,女 442 名)。所有临床评估均由一名经验丰富的检查者在自然光线下进行。收集的数据包括年龄和缺失的牙齿。
研究结果表明,20.8%的样本在 6 岁之前就已经失去了乳牙(>0.05),尽管没有观察到性别差异,但男性(12.6%)比女性(8.2%)更常见。下颌弓(61.8%)比上颌弓(38.2%)更常见。根据牙齿类型与早期牙齿缺失的频率,磨牙(98.2%)是最常见的过早缺失的牙齿,其次是切牙(1.5%)和尖牙(0.3%)。左下乳第一磨牙(42.3%)是最常见的缺失牙齿,8 岁儿童的缺失频率最高(38.9%)。
本研究表明,在下颌乳磨牙是目前研究中最常见的缺失牙齿,早期缺失的情况非常普遍。
早期乳牙缺失会导致许多错合畸形问题,主要表现为牙弓长度差异。早期发现和管理与早期乳牙缺失相关的空间问题有助于减少错合畸形问题。
