evaluation of oral hygiene to enhance the prophylaxis of complications specifically of dental caries inchildren with disturbances in tooth formation (DTF) who live on radiologically contaminated territories after theChornobyl NPP (ChNPP) accident.
Children aged 6-14 years (n = 1470) with DTF were the study subjects examined in 2012-2016. Among them there were (n = 528) residents of the zones III and IV of radiological contamination after theChNPP accident with 137Cs soil contamination density 1-15 Ci/km2. The effective radiation dose in them was notexceeding 1 mSv/year. The Green-Vermillion and Silness-Loe oral hygiene indices were assesses within clinicalexamination methods.
The worth oral hygiene was revealed in children having got the DTF, compensated chronic diseases oforgans and systems, and in those with burdened radiation history. The Green-Vermilion and Silness-Loe indices were1.7 ± 0.51 and 1.65 ± 0.46 respectively.
A significant deterioration in oral hygiene confirmed by the highest values of the Green-Vermillion index (1.7 ± 0.51; p < 0.001 - «unsatisfactory oral hygiene» criterion) and Silness-Loe index (1.65 ± 0.46; p < 0.001 -«poor oral hygiene» criterion) was found in children with DTF aged 6-14 years being residents of contaminated areasas a result of the Chernobyl accident. The revealed deterioration may be due to a set of negative factors, includingthe impact of ionizing radiation in low doses and peculiarities of social status. Results of the questioning of surveyed pediatric contingents both having got an DTF and with no defects of the hard tissues of teeth indicate aninsufficient level of knowledge and skills in hygienic care of oral cavity regardless of the area of residence.Development of a set of measures to prevent the DTF complications in children should be carried out taking intoaccount the state of oral hygiene, level of knowledge and skills in oral care, and include the use of hygiene products, namely toothpastes and anti-caries mouthwashes.
评估口腔卫生，以增强对牙齿形成障碍（DTF）儿童的预防措施，特别是在切尔诺贝利核电站（ChNPP）事故后生活在放射性污染地区的儿童。
2012-2016 年，我们对 1470 名年龄在 6-14 岁的 DTF 儿童进行了研究。其中有（n = 528）居住在 ChNPP 事故后放射性污染区 III 和 IV 区的儿童，土壤污染密度为 1-15 Ci/km2。他们的有效辐射剂量不超过 1 mSv/年。使用临床检查方法评估了 Green-Vermillion 和 Silness-Loe 口腔卫生指数。
在患有 DTF、补偿性慢性器官和系统疾病以及有辐射史的儿童中，口腔卫生状况得到改善。Green-Vermillion 和 Silness-Loe 指数分别为 1.7 ± 0.51 和 1.65 ± 0.46。
通过最高值的 Green-Vermillion 指数（1.7 ± 0.51;p < 0.001-“不满意的口腔卫生”标准）和 Silness-Loe 指数（1.65 ± 0.46;p < 0.001-“不良口腔卫生”标准）证实，6-14 岁患有 DTF 的儿童的口腔卫生状况显著恶化，这些儿童是切尔诺贝利事故造成的污染地区的居民。发现的恶化可能是由于一系列负面因素造成的，包括低剂量电离辐射的影响和社会地位的特点。对接受调查的儿科人群进行问卷调查，结果表明，无论居住在哪个地区，他们对口腔卫生护理的知识和技能水平都不足。为了预防 DTF 并发症，应制定一整套措施，考虑到口腔卫生状况、口腔护理知识和技能水平，并包括使用卫生产品，如牙膏和防龋漱口水。
