Caries and its risk factors in young children in five different countries.

The state of oral health plays an essential role in human comprehensive health. Nevertheless, although considerable improvement in oral health caries has been noted in both developed and newly developing countries, caries is still widespread among children. Although it can be monitored, caries cannot be properly eliminated. MATERIALS AND METHODS. This investigation, performed in cooperation with Jena Hospital in Germany, was conducted in five countries from 2002-2008. The cities Riga (Latvia), Ouro Preto (Brazil), Erfurt (Germany), Volgograd (Russia) and Minsk (Belorus) were engaged in this investigation. Children at the age of 26-34 months were surveyed. Consistent with the research design, the mothers filled out questionnaires about the children's health, and an examination of the children's oral health was performed. The statistics program SPSS 15.0 was used to analyze the obtained data, and the correlations between changing findings were expressed by the Spearmen rank correlation coefficient (r). RESULTS. In this study, 472 children were observed: 179 from Riga, 152 from Erfurt, 62 from Ouru Preto, 116 from Minsk and 84 from Volgograd. A direct correlation existed between the country and plaque (r=0.16) and caries (dmft) (r=-0.11). The direct correlation between dmft and Streptococcus mutans (r=-0.36) was characteristic of children from Erfurt. The lowest dmft index (0.62) was present in children from Erfurt, and the highest (1.57) in children from Ouro Preto. CONCLUSIONS. The frequency and prevalence of caries in young children in Riga is high; it was the lowest in Erfurt and the highest - in Brazil. Plaque and dt were one of the indices with a direct relationship in Riga, Brazil and Minsk. Poor oral hygiene, irregular tooth brushing and the consumption of cariogenic foods and drinks are the most important caries risk factors among children at the age of 2-3 years. The mother's knowledge and attitude affect the child's oral health.

Health-promoting schools: an opportunity for oral health promotion.

Schools provide an important setting for promoting health, as they reach over 1 billion children worldwide and, through them, the school staff, families and the community as a whole. Health promotion messages can be reinforced throughout the most influential stages of children's lives, enabling them to develop lifelong sustainable attitudes and skills. Poor oral health can have a detrimental effect on children's quality of life, their performance at school and their success in later life. This paper examines the global need for promoting oral health through schools. The WHO Global School Health Initiative and the potential for setting up oral health programmes in schools using the health-promoting school framework are discussed. The challenges faced in promoting oral health in schools in both developed and developing countries are highlighted. The importance of using a validated framework and appropriate methodologies for the evaluation of school oral health projects is emphasized.

Effectiveness of a powered toothbrush compared with a manual toothbrush for orthodontic patients with fixed appliances.

Orthodontic patients with fixed appliances have an increased risk for caries and gingivitis. Therefore, the use of special toothbrushes and additional cleaning tools is recommended. The aim of this longitudinal study was to compare the plaque removal efficacy and reduction of gingivitis from using a powered toothbrush compared to a manual toothbrush in patients with fixed orthodontic appliances. Eighty subjects were included in the study with a mean age of 13.53 years. After a baseline examination, patients were randomly assigned to two groups and their teeth were professionally cleaned. The patients were assessed at baseline, two and four weeks using the QHI and SBI. The results showed a significantly superior plaque removal effect (p = 0.0001) and reduction of gingival inflammation (p < 0.05) in those patients using the powered versus the manual toothbrush. The findings were for both whole mouth and partial mouth assessments. In accordance with previous studies, it was demonstrated that the use of a powered toothbrush can be recommended for orthodontic patients with fixed appliances.
