The 1986 accident at the Chernobyl Nuclear Power Plant led to large-scale changes in the environmental situation. The purpose of our study was to conduct a comparative analysis of the morphological states of the dentition of individuals living in regions exposed to radiation to determine the groups at risk for the main classes of dental anomalies. We believe our results will support the development of a differentiated system for dental rehabilitation and follow-up of individuals exposed to radiation. The prevalence rate of dental anomalies was studied in 1,889 patients of both sexes divided by age in accordance with dentition formation stages and by regions of residence in accordance with the 137Cs soil-contamination level. A statistically significant decrease was observed in the number of patients with normal dentition for their age among those who had been exposed to prenatal radiation. A sharp increase in combined dental anomalies was revealed in patients who lived in regions with a137Cs soil-contamination level ranging from 555 to 1665 GBq/km2; concomitantly, multidirectional fluctuations were observed in the numbers of tooth and occlusion anomalies. Among the examined population, the most severe pathology of the oral organs was found in prenatally irradiated patients (born between April 26, 1986, and April 30, 1987). The prevalence of dental anomalies is interrelated not only with the level of radioactive contamination in the soil of the dwelling area, but also with the age of the surveyed individuals at the moment of the accident.

生活在放射性核素污染地区的人的牙齿异常。

1986年切尔诺贝利核电站的事故导致环境状况发生了大规模变化。我们研究的目的是对生活在受辐射照射区域的个体的牙列形态状态进行比较分析，以确定处于主要类别牙齿异常风险中的人群。我们相信我们的研究结果将支持开发一套差异化的系统，用于牙科康复和受辐射个体的随访。研究了1,889名男女患者的牙齿畸形患病率，按照年龄划分了年龄（根据牙列的形成阶段）和居住地区（根据137Cs的土壤污染水平）。在接受产前放疗的患者中，年龄范围内具有正常牙列的患者数量在统计学上显着下降。居住在a137Cs土壤污染水平范围为555至1665 GBq / km2的地区的患者中，牙齿综合异常现象急剧增加。同时，在牙齿和咬合异常的数量上观察到多方向的波动。在接受检查的人群中，口腔器官的最严重病理发现是在产前受辐照的患者中（出生于1986年4月26日至1987年4月30日之间）。牙齿异常的发生率不仅与居住区土壤中的放射性污染水平有关，而且还与事故发生时被调查者的年龄有关。
