Effectiveness of oral hygiene after supervised tooth-brushing education in six-year-old children at a primary school in Vietnam

Abstract

Background: The prevalence of dental caries is very high among Vietnamese children why methods and techniques for good oral hygiene behaviours therefore is very important in caries prevention. Aim: To assess oral hygiene before and after supervised tooth-brushing education in six-yearold children. Design: A pilot study with a pre-post-test design was used. Forty children, six years of age, at a primary school in Hanoi, participated in the study. The modified Bass tooth-brushing method were taught. Oral hygiene, i.e. dental plaque, was assessed on each tooth surface before the tooth-brushing education and after one week. Results: There was a distinct and significant improvement in tooth-brushing skills among sixyear-old children of both genders after the tooth-brushing education. The rate of dental plaque was reduced by 40% after the education. An improvement in cleaning could be seen on all four tooth surfaces (buccal, lingual, mesial and distal). Conclusion: School-based education in tooth-brushing technique are very effective for improving oral hygiene among six year olds.

Variáveis contextuais e individuais associadas à cárie dentária

“…O objetivo do "Programa Sempre Sorrindo" é oferecer cuidados odontológicos aos estudantes de baixa renda residentes em áreas de exclusão social 10,15,27 . No âmbito do referido programa foram desenvolvidas atividades que envolveram a coleta e registro de informações clínicas e as relacionadas a saúde bucal, qualidade de vida, dados socioeconômicos, comportamentais, de acesso a serviço odontológico dos escolares.…”

“…Fatores mais distais como o Índice de Desenvolvimento Humano, o Índice de Gini, o capital social 2,8,9 e fatores intermediários como renda média do bairro, renda familiar mensal, tipo de moradia, número de moradores na residência e escolaridade dos pais são indicadores de risco à cárie dentária e demais problemas bucais 10,11,12,13 . Semelhantemente, fatores comportamentais como higiene bucal deficiente decorrente da escovação dentária irregular, da não utilização do fio dental e do consumo excessivo e inadequado de carboidratos contribuem para maior prevalência de cárie dentária 14,15,16,17,7 . Concomitantemente, fatores individuais contribuem para aumento de risco de cárie dentária 18,19,20,21 .…”

Effektivität des differenziellen Lernens im Rahmen der Mundhygieneinstruktion bei Grundschülern

“…Besonders die oralen Zahnflächen werden von Kindern schlechter gereinigt als die bukkalen (Korins et al 1982;Unkel et al 1995;van Palenstein Helderman et al 2006). In einer vietnamesischen Studie wurde gezeigt, dass sechsjährige Schülerinnen und Schülern nur 40% des Biofilms entfernen können (Lindmark et al 2012). In einer argentinischen Studie beseitigten 49% der von Sechs-bis Siebenjährigen den dentalen Biofilm in ausreichendem Maße, wobei nur 50,6% alle Sextanten putzen, aber keine einheitliche Systematik anwendeten (Rossi et al 2016).…”
