STATEMENT OF THE PROBLEM
Dental caries is the most common chronic childhood disorders throughout the world. The dmft (decayed, missing, and filled primary teeth) and DMFT (decayed, missing, and filled permanent teeth) are some of the most important epidemiological indices in dentistry. Evaluation of these two indicators in the population can help in future planning of healthcare programs to improve oral health status.
PURPOSE
The aim of this study was to evaluate these indicators and the related factors in first-grade primary school students in Rafsanjan urban area to determine their present status, which might be helpful for future health care planning.
MATERIALS AND METHOD
In this cross-sectional study, DMFT index of first permanent molar and dmft were evaluated by census method on 2031 first-grade primary school students in Rafsanjan urban area in 2018 (May-June). Dental examination was done using a mirror and probe under natural light according to World Health Organization criteria. The data were then analyzed using independent two-sample t-test, one-way ANOVA, Tukey's multiple comparisons test, Kolmogorov-Smirnov nonparametric test and Leven's test in SPSS version 21 software.
RESULTS
The mean and standard deviation of dmft index and DMFT index of first permanent molar were 6.37 ± 3.40 and 0.30 ± 0.72, respectively. The proportion of caries free students was 4.1%. A significant association was found between the values of these indices and school type, the level of education of parents, parental occupation, family size, and frequency of brushing and the use of floss ( < 0.05). However, there was no significant association between these two indices with gender (= 0.347 and = 0.593, respectively).
CONCLUSION
The results of this study showed high prevalence of caries in first-grade primary school students in Rafsanjan. Therefore, to improve this situation, more attention is needed for proper oral health program planning and education of families concerning oral hygiene and dental preventive measures.
问题陈述
龋齿是全球最常见的儿童慢性疾病。乳牙龋失补牙数（dmft，即decayed, missing, and filled primary teeth）和恒牙龋失补牙数（DMFT，即decayed, missing, and filled permanent teeth）是牙科领域一些最重要的流行病学指标。评估人群中的这两个指标有助于未来制定医疗保健计划以改善口腔健康状况。
目的
本研究旨在评估拉夫桑詹市区一年级小学生的这些指标及相关因素，以确定他们的当前状况，这可能有助于未来的医疗保健规划。
材料与方法
在这项横断面研究中，于2018年5月至6月采用普查法对拉夫桑詹市区2031名一年级小学生的第一恒磨牙DMFT指数和乳牙dmft指数进行了评估。根据世界卫生组织标准，在自然光下使用口镜和探针进行口腔检查。然后在SPSS 21版软件中使用独立两样本t检验、单因素方差分析、Tukey多重比较检验、Kolmogorov-Smirnov非参数检验和Levene检验对数据进行分析。
结果
乳牙dmft指数和第一恒磨牙DMFT指数的均值及标准差分别为6.37±3.40和0.30±0.72。无龋学生的比例为4.1%。发现这些指数的值与学校类型、父母教育程度、父母职业、家庭规模、刷牙频率和使用牙线之间存在显著关联（P<0.05）。然而，这两个指数与性别之间均无显著关联（分别为P = 0.347和P = 0.593）。
结论
本研究结果显示拉夫桑詹市区一年级小学生龋齿患病率较高。因此，为改善这种情况，需要更加关注适当的口腔健康计划规划以及对家庭进行口腔卫生和牙齿预防措施方面的教育。
