Anecdotally, tooth wear is increasing, perhaps attributable to diet. The irreversible surface loss may result in sensitivity and loss of form and function. Little data exist on the prevalence of tooth wear in Australian children. This study investigated consumption of potentially erosive foods and drinks, examining the prevalence, distribution of tooth wear and associations in a sample of children.
Parents of 350, 6-12-year-olds reported their child's oral hygiene, dietary intake, medical and dental histories; 154 children (subsample) were examined. Associations were studied with single and multivariable analyses.
Tooth wear was parentally reported for 17% (59 children of the study population) and observed in 66% (102 of the subsample), particularly affecting primary teeth. Significant risk factors for parentally reported tooth wear were: consuming 2-4 cups soft drink/day (OR = 9.52), citrus flavoured sweets/gums ≥1/day (5.10), citrus fruits 1-2/wk (4.28); tooth grinding (5.32); medical condition present (2.48); male gender (2.80). Drinking 2-4 cups fruit juice/day was a significant risk factor for both parentally reported (3.23) and observed tooth wear (3.97).
Tooth wear appeared under-reported as some parents were unaware their child's teeth were affected. Significant risk factors for tooth wear were identifiable from children's histories. Risk factors should be addressed early so that tooth wear in the primary dentition does not affect permanent teeth.
据传闻，牙齿磨损正在增加，这可能与饮食有关。不可逆转的表面损失可能导致敏感和形态与功能丧失。澳大利亚儿童牙齿磨损的流行程度的数据很少。本研究调查了潜在腐蚀性食物和饮料的消费情况，在儿童样本中检查了牙齿磨损的患病率、分布和相关性。
350 名 6-12 岁儿童的家长报告了他们孩子的口腔卫生、饮食摄入、医疗和牙科史；对 154 名儿童（子样本）进行了检查。采用单变量和多变量分析研究相关性。
17%（研究人群中的 59 名儿童）的家长报告了牙齿磨损，66%（子样本中的 102 名儿童）观察到了牙齿磨损，主要影响乳牙。家长报告的牙齿磨损的显著危险因素是：每天饮用 2-4 杯软饮料（OR = 9.52）、每天食用≥1 份柑橘味糖果/口香糖（5.10）、每周食用 1-2 份柑橘类水果（4.28）；磨牙（5.32）；存在医疗状况（2.48）；男性（2.80）。每天饮用 2-4 杯果汁是家长报告（3.23）和观察到的牙齿磨损（3.97）的显著危险因素。
牙齿磨损似乎被低估了，因为有些家长不知道他们孩子的牙齿受到了影响。牙齿磨损的显著危险因素可从儿童病史中识别出来。应及早解决这些危险因素，以免乳牙的牙齿磨损影响恒牙。
