The present study was designed to determine the prevalence of premature loss of primary teeth and its effect on malocclusion in Eastern Province, Saudi Arabia.
This is an observational, cross-sectional study that included 307 male children aged 9-11 years old. Clinical examinations were performed using a disposable sharp explorer, a UNC periodontal probe and a dental mirror. The samples were examined clinically to detect the following traits: Angle's classification of malocclusion, overjet, overbite, anterior open-bite, lateral open-bite, midline shift and cross-bite. Additionally, a dental caries examination was performed using WHO methods. Questionnaires in Arabic were coded and sent to the students' parents.
The mean DMFT was 5.61 (SD = 3.01). The d-component was the highest, with a mean of 4 (SD = 2.83). Of the 307 children, it was found that 204 (66.4%) had a high DMFT score, which is defined as a score above 4. It was found that 156/307 (51%) children had premature loss of deciduous teeth.
A high prevalence of premature loss of teeth was found in this study. This finding emphasizes the importance of increasing awareness levels about this issue and focuses attention on the need for more preventive efforts to maintain healthy and normal dentitions that would improve the masticatory function and aesthetics of individuals and the whole population. In addition, the findings emphasize the importance of the early detection of premature loss of primary teeth to prevent future malocclusion.
本研究旨在确定沙特阿拉伯东部省份乳牙过早脱落的患病率及其对错牙合畸形的影响。
这是一项观察性横断面研究，纳入了307名9至11岁的男性儿童。使用一次性尖锐探针、UNC牙周探针和牙镜进行临床检查。对样本进行临床检查以检测以下特征：安氏错牙合分类、覆盖、覆牙合、前牙开牙合、侧方开牙合、中线偏移和反牙合。此外，采用世界卫生组织的方法进行龋齿检查。用阿拉伯语编写的问卷进行编码后发送给学生家长。
平均DMFT为5.61（标准差=3.01）。d成分最高，平均为4（标准差=2.83）。在307名儿童中，发现204名（66.4%）的DMFT评分较高，即评分高于4。发现156/307（51%）的儿童乳牙过早脱落。
本研究发现牙齿过早脱落的患病率较高。这一发现强调了提高对该问题认识水平的重要性，并将注意力集中在需要更多预防措施以维持健康和正常牙列的必要性上，这将改善个人和整个人口的咀嚼功能和美观。此外，研究结果强调了早期发现乳牙过早脱落以预防未来错牙合畸形的重要性。
