Dental anomaly is one of the major problems in a child born with cleft lip and palate. These anomalies have deleterious effects on the dentition leading to aesthetic problems, impairment of mastication andimproper phonation. The aim of our study was to find out the prevalence of dental anomalies in patient with cleft lip and/or palate radiographically.
A descriptive cross-sectional study was conducted from the 208 radiographs, collected by the convenience samplingtechnique with cleft lip and/or palate in Department of Burns, Plastic and Reconstructive Surgery, Nepal Cleft and Burn Centre, Kirtipur Hospital from January 2017 to July 2019.Ethical clearance for the study was obtained from Institutional Review Committee. Demographic data were collected and radiographs were evaluated for possible dental anomalies. Data obtained were entered and analysed in Statistical Package for Social Sciences version 23.
Dental anomalies were highly prevalent among cleft lip and palate patients with at least one anomaly present in 188 (90.4%) of patients with male 120 (57.4%) presenting more anomalies than female 88 (42.6%) population. The most common anomaly was dental agenesis 161 (77.9%). The prevalence of positional anomaly, morphological anomaly and supernumerary teeth were found to be 54 (26%), 33 (15.9%) and 20 (10%) respectively. Lateral incisor showed the highest incidence of agenesis among all other missing teeth 223 (65.2%).
The prevalence of dental anomalies among patients with cleft lip and/or palate was found to be high. Tooth agenesis was the most common anomaly observed in the study with lateral incisor having the highest incidence of agenesis.
牙齿异常是唇腭裂患儿的主要问题之一。这些异常对牙齿有不良影响，导致美观问题、咀嚼功能受损和发音不当。本研究的目的是通过影像学检查发现唇腭裂患者的牙齿异常的患病率。
这是一项描述性的横断面研究，通过便利抽样技术从 208 张唇腭裂患者的 X 光片中收集数据，这些 X 光片来自尼泊尔裂隙和烧伤中心烧伤、整形和重建外科，时间为 2017 年 1 月至 2019 年 7 月。本研究获得了机构审查委员会的伦理批准。收集了人口统计学数据，并对 X 光片进行评估，以确定可能存在的牙齿异常。获得的数据输入到社会科学统计软件包 23 版进行分析。
牙齿异常在唇腭裂患者中非常普遍，188 名（90.4%）患者至少存在一种异常，其中 120 名（57.4%）男性患者比 88 名（42.6%）女性患者表现出更多的异常。最常见的异常是牙齿缺失 161 例（77.9%）。发现位置异常、形态异常和多生牙的患病率分别为 54 例（26%）、33 例（15.9%）和 20 例（10%）。在所有缺失的牙齿中，侧切牙的缺失率最高，为 223 例（65.2%）。
唇腭裂患者的牙齿异常患病率较高。牙缺失是本研究中观察到的最常见的异常，侧切牙的缺失率最高。
