OBJECTIVE: Dental anomalies (DA) can affect paediatric patients' aesthetics, function, and psychological well-being. There is a lack of data about the prevalence of DA in children in Kuwait. This study aimed to investigate the prevalence and distribution of DA amongst schoolchildren aged 8 to 12 years. METHODS: A retrospective study was conducted using panoramic digital radiographs of children who attended a single dental center. All radiographs were evaluated by 2 calibrated and trained examiners. RESULTS: DA were present in 110 (20.1%) out of the 546 panoramic radiographs examined: 53.6% in females and 46.4% in males. The mean age of children with DA (9.83 ± 1.29) was similar to that of children with no anomalies (9.96 ± 1.46). The most prevalent anomaly was dental agenesis (9.3%), followed by taurodontism (6.6%) and ectopic eruption (EE, 2%). DA were more common in the maxilla (58.2%) compared to the mandible (41.8%, P = .042). Congenitally missing teeth were significantly more frequent in the mandible (56.9%) than in the maxilla (43.1%, P = .003). EE was significantly more common in the maxilla (90.9%) than in the mandible (9.1%, P = .024). Microdontia and root dilacerations were only present in males, whilst supernumerary teeth, transposition, and impacted teeth were noted in females only. CONCLUSIONS: The prevalence of DA amongst schoolchildren in Kuwait was considered to be relatively high. Certain DA were associated with gender. The significant prevalence of DA highlights the need for early diagnosis using panoramic radiographs, particularly during the ages of 9 and 10, in order to ensure effective patient management.
目的:牙齿异常(DA)会影响儿科患者的美观、功能和心理健康。科威特儿童中 DA 的患病率数据缺乏。本研究旨在调查 8 至 12 岁学龄儿童中 DA 的患病率和分布情况。
方法:使用单一牙科中心儿童的全景数字射线照片进行回顾性研究。所有射线照片均由 2 名经过校准和培训的检查者进行评估。
结果:在 546 张全景射线照片中发现了 110 例(20.1%) DA:女性占 53.6%,男性占 46.4%。有 DA 的儿童(9.83±1.29)的平均年龄与无异常的儿童(9.96±1.46)相似。最常见的异常是牙齿缺失(9.3%),其次是尖牙畸形(6.6%)和异位萌出(EE,2%)。DA 在上颌(58.2%)比下颌(41.8%)更常见(P=.042)。先天性缺失的牙齿在下颌(56.9%)比在上颌(43.1%)更常见(P=.003)。EE 在上颌(90.9%)比下颌(9.1%)更常见(P=.024)。小牙和根扭曲仅见于男性,而多生牙、错位和阻生牙仅见于女性。
结论:科威特学龄儿童中 DA 的患病率被认为相对较高。某些 DA 与性别有关。DA 的显著患病率突出表明需要使用全景射线照片进行早期诊断,特别是在 9 岁和 10 岁时,以确保有效的患者管理。
