Dental diseases in children have been reduced in recent decades in developed countries, although trends remain unclear in other countries. Oral healthcare in Argentina is based on demand and depends on a patient's health insurance coverage. The objective of this study was to determine the oral health situation of the population of six-year-olds in Berisso, Buenos Aires province (Argentina).
A cross-sectional observational study was performed on schoolchildren from public and private schools. The following factors were evaluated: DMFT, DMFS, dft, dfs, significant caries (SiC), filled, decayed and missing teeth, and the prevalence of caries in both primary and permanent teeth. Data was recorded concerning malocclusion, ankylosis, dental fluorosis, DDE index modified, urgent healthcare needs, healthcare system use, orthodontic treatments, filling materials, school type and socioeconomic position.
The study was carried out on 804 schoolchildren. The overall prevalence of caries was 70% (temporary dentition 67.9%, permanent dentition 16.3%). The dft index was 4.52 for males and 4.77 for females. For males, dfs index scored 8.78 and for females, it scored 9.27. DMFT index was 0.45 for males and 0.51 for females. DMFS index scored 0.68 for males and 0.80 for females. There were differences between socioeconomic groups (employees and manual workers) in DMFT and DMFS indexes. Of the study population, 54% had never been seen by a dentist prior to the study. For children who had visited a dentist, 71% attended state public services.
Oral indices in Berisso were worse than in other Argentinean studies and were far from the World Health Organization global goals. There is an urgent need to strengthen the effectiveness of preventive care.
尽管其他国家的趋势尚不清楚，但在过去几十年中，发达国家儿童的牙科疾病已经减少。阿根廷的口腔保健服务基于需求，并取决于患者的健康保险覆盖范围。本研究的目的是确定布宜诺斯艾利斯省贝里索（阿根廷）六岁儿童的口腔健康状况。
对公立和私立学校的学童进行了横断面观察性研究。评估了以下因素：DMFT、DMFS、dft、dfs、显著龋齿（SiC）、填充、龋齿和缺失牙齿以及乳牙和恒牙的龋齿患病率。记录了错牙合、固位、氟牙症、改良 DDE 指数、紧急医疗保健需求、医疗保健系统使用、正畸治疗、填充材料、学校类型和社会经济地位的数据。
本研究共纳入 804 名学童。龋齿总患病率为 70%（乳牙 67.9%，恒牙 16.3%）。dft 指数男性为 4.52，女性为 4.77。男性的 dfs 指数为 8.78，女性为 9.27。DMFT 指数男性为 0.45，女性为 0.51。DMFS 指数男性为 0.68，女性为 0.80。DMFT 和 DMFS 指数在社会经济群体（员工和体力劳动者）之间存在差异。研究人群中，54%的人在研究前从未看过牙医。对于看过牙医的儿童，71%的人去了公立服务机构。
贝里索的口腔指数比阿根廷其他研究差，远未达到世界卫生组织的全球目标。迫切需要加强预防保健的有效性。
