Abstract

Aim: The aim of the study was to examine the 20-year trend in dental caries and associated determinants among adults in Lithuania after the country restored its independence.

Material and methods: Data from two cross-sectional national surveys included samples of 35-44-year-olds (adults) and 65-74-year-olds (early elderly). The 1997/1998 survey (first survey) recruited a stratified random sample of 569 individuals from 10 selected areas in Lithuania (response rate 52%), and the 2017/2019 survey (second survey) recruited a stratified random sample of 723 individuals from 5 biggest Lithuanian cities and one randomly selected peri-urban/rural area from each of 10 Lithuanian counties (response rate 53%). The information about the social (sex, residence, education) and behavioral (toothbrushing frequency, use of fluoridated toothpaste, and last dental visit) determinants was collected via self-reports using the World Health Organization (WHO) Oral Health Questionnaire for Adults questions. Information about the fluoride level in the drinking water was retrieved from the water suppliers. Dental caries was recorded at the surface level following the WHO criteria by two calibrated examiners, one at each of the national surveys. Bivariate and multivariate analyses were used.

Results: According to multivariable negative binomial regression analysis, in adults, 67% lower DS scores (IRR 0.33, 95% CI 0.26-0.42) and in early elderly 47% lower DS scores (IRR 0.53, 95% CI 0.38-0.74) were observed in the second survey. Adults in the second survey (vs. first survey) had 62% lower MT scores (IRR 0.38, 95% CI 0.32-0.46), and the early elderly had 19% lower MT scores (IRR 0.81, 95% CI 0.72-0.92). Adults in the second survey had 21% lower DMFT scores (IRR 0.79, 95% CI 0.73-0.85). The changes in behavioral determinants were observed over the 20-year period.

Conclusion: An improvement in dental health during the 20-year period, mainly related to reduction in untreated caries and missing teeth, was observed in adults and early elderly. However, early elderly still had high numbers of missing teeth. The decrease in total caries experience during the 20 years was significant only in adults. Our findings support an urgent need to design and implement national oral health promotion and prevention programs with increased focus on oral self-care and fluoridated toothpaste use.

后苏联立陶宛成年人龋齿和相关决定因素的20年趋势:重复横断面研究。

目的:本研究的目的是研究立陶宛恢复独立后成年人龋齿和相关决定因素的20年趋势。材料和方法:数据来自两项横断面全国调查，包括35-44岁(成年人)和65-74岁(老年早期)的样本。1997/1998年调查(第一次调查)从立陶宛10个选定地区招募了569人的分层随机样本(回复率52%)，2017/2019年调查(第二次调查)从立陶宛5个最大的城市和立陶宛10个县中随机选择的一个城郊/农村地区招募了723人的分层随机样本(回复率53%)。社会(性别、居住地、受教育程度)和行为(刷牙频率、使用含氟牙膏和最后一次看牙医)决定因素的信息通过使用世界卫生组织(WHO)成人口腔健康问卷问题的自我报告收集。有关饮用水中氟化物含量的信息是从供水商处获取的。根据世卫组织的标准，由两名经过校准的检查员在表面水平记录龋齿，每项国家调查都有一名检查员。采用双变量和多变量分析。结果:根据多变量负二项回归分析，第二次调查中，成人DS评分降低67% (IRR 0.33, 95% CI 0.26 ~ 0.42)，老年早期DS评分降低47% (IRR 0.53, 95% CI 0.38 ~ 0.74)。第二次调查的成年人(与第一次调查相比)MT评分降低62% (IRR 0.38, 95% CI 0.32-0.46)，早期老年人MT评分降低19% (IRR 0.81, 95% CI 0.72-0.92)。在第二次调查中，成年人DMFT评分降低21% (IRR 0.79, 95% CI 0.73-0.85)。行为决定因素的变化是在20年期间观察到的。结论:在20年期间，在成人和早期老年人中观察到牙齿健康的改善，主要与未经治疗的龋齿和缺牙的减少有关。然而，早期老年人仍然有大量的牙齿缺失。在20年中，龋齿总经历的减少仅在成人中显著。我们的研究结果支持迫切需要设计和实施国家口腔健康促进和预防计划，增加对口腔自我保健和含氟牙膏使用的关注。

期刊介绍： ''Caries Research'' publishes epidemiological, clinical and laboratory studies in dental caries, erosion and related dental diseases. Some studies build on the considerable advances already made in caries prevention, e.g. through fluoride application. Some aim to improve understanding of the increasingly important problem of dental erosion and the associated tooth wear process. Others monitor the changing pattern of caries in different populations, explore improved methods of diagnosis or evaluate methods of prevention or treatment. The broad coverage of current research has given the journal an international reputation as an indispensable source for both basic scientists and clinicians engaged in understanding, investigating and preventing dental disease.
