To examine the relationship between dental anxiety, dental attendance and past treatment history in 5-year-old children after taking into account confounding influences.
A cross sectional study of all 5-year-old children living in Ellesmere Port and Chester. All children were clinically examined and dmft and its components were recorded. A postal questionnaire was sent to parents of participating children to identify whether children attended the dentist on a regular asymptomatic basis or only when experiencing problems. Additionally parents were asked to judge whether they and their child were anxious about dental treatment. The socio-economic status of the family was measured using the Townsend Material Deprivation Index of the electoral ward in which they resided. The bivariate relationships between anxiety and reported attendance experience, past extraction and restoration history were using chi-square and t-tests. Multiple logistic regression analyses identify predictors for dental anxiety.
A total of 1,745 children received both a clinical examination and a questionnaire and 1,437 parents responded, a response rate of 82.3%. One in ten parents (10.8b) judged their child to be dentally anxious. Anxious children had significantly (p<0.001] more caries experience (dmft 2.58 vs 1.12). Multiple logistic regression analyses confirmed that anxious children were more likely to be irregular attenders (OR 3.33, 95% Cl 2.22, 5.00), have anxious parents (OR 1.60,95% Cl 1.09, 2.36), and to have undergone dental extraction in the past[OR 3.50, 95% CI 2.10, 5.85), after controlling for gender and socio-economic status. A past history of restoration was not a significant predictor of anxiety after controlling for other factors.
Dental anxiety is a fairly common condition in 5-year-old children in the North West of England. It is closely associated with asymptomatic, irregular attendance pattern, a history of extraction and having a dentally anxious parent. The cause and effect dynamics of these relationships need to be determined.
在考虑混杂因素影响的情况下，研究5岁儿童的牙科焦虑、看牙就诊情况和既往治疗史之间的关系。
对居住在埃尔斯米尔港和切斯特的所有5岁儿童进行横断面研究。对所有儿童进行临床检查并记录dmft及其组成部分。向参与研究儿童的家长发送邮政问卷，以确定儿童是定期无症状看牙还是仅在出现问题时才看牙。此外，还要求家长判断他们自己和孩子是否对牙科治疗感到焦虑。使用他们居住的选举选区的汤森物质匮乏指数来衡量家庭的社会经济地位。使用卡方检验和t检验分析焦虑与报告的就诊经历、既往拔牙和补牙史之间的双变量关系。多元逻辑回归分析确定牙科焦虑的预测因素。
共有1745名儿童接受了临床检查和问卷调查，1437名家长做出了回应，回应率为82.3%。十分之一的家长（10.8%）认为他们的孩子存在牙科焦虑。焦虑儿童的龋齿经历明显更多（p<0.001，dmft为2.58，而无焦虑儿童为1.12）。多元逻辑回归分析证实，在控制了性别和社会经济地位后，焦虑儿童更有可能不定期看牙（比值比3.33，95%置信区间2.22，5.00）、有焦虑的家长（比值比1.60，95%置信区间1.09, 2.36），并且过去曾接受过拔牙（比值比3.50，95%置信区间2.10, 5.85）。在控制了其他因素后，既往补牙史并不是焦虑的显著预测因素。
在英格兰西北部，牙科焦虑在5岁儿童中是一种相当常见的情况。它与无症状不定期就诊模式、拔牙史以及有牙科焦虑的家长密切相关。这些关系的因果动态需要确定。
