To assess the association amongst oral hygiene practices, untreated dental caries (UDC) and clinical consequences of UDC in pre- and primary school children aged 3-5 and 6-7 years.
A total of 250 subjects were recruited. The demographic and oral hygiene data were collected using a closed-ended questionnaire. The UDC was measured using the 'd/D' component of the decayed, missing, filled teeth (dmft/DMFT) index, and its clinical consequences were recorded using the 'p/P' component of the pulpal involvement, ulceration, fistula and abscess (pufa/PUFA) index. The data were analyzed by multiple logistic regression.
Overall, 94.2% and 56.5% of the participants had one or more UDC and pulp involvement (p ≥ 1), respectively in 3-5-year-old age group. In the 6-7-year- age group the prevalence of UDC was 26.7% and the pulp involvement was 11.6%. Children who brushed with their fingers were 4.7 times more likely to have UDC (crude odds ratio [COR] = 4.71; 95% CI: 1.21-18.40). Twice-daily brushing resulted in a 39% (p = 0.732) lower likelihood of having UDC compared with once-daily brushing (COR = 0.61; 95% CI: 0.04, 10.09). Children with irregular brushing frequency were 3.2 times more likely to have pulpal involvement (COR = 3.21; 95% CI: 1.74-5.93).
Finger brushing, irregular frequency of brushing and lack of parental supervision whilst brushing were associated with UDC and its consequences.
评估 3-5 岁和 6-7 岁学龄前和小学生的口腔卫生习惯、未经治疗的龋齿 (UDC) 与 UDC 临床后果之间的关系。
共招募了 250 名受试者。使用封闭式问卷收集人口统计学和口腔卫生数据。使用“d/D”成分测量 UDC，使用“p/P”成分记录牙髓受累、溃疡、瘘管和脓肿 (pufa/PUFA) 指数的临床后果。使用多因素逻辑回归分析数据。
总体而言，3-5 岁年龄组中，94.2%和 56.5%的参与者分别有一颗或多颗 UDC 和牙髓受累（p≥1）。在 6-7 岁年龄组中，UDC 的患病率为 26.7%，牙髓受累为 11.6%。用手指刷牙的儿童发生 UDC 的可能性高 4.7 倍（粗比值比 [COR] = 4.71；95%可信区间：1.21-18.40）。与每日刷牙一次相比，每日刷牙两次患 UDC 的可能性降低 39%（p = 0.732；COR = 0.61；95%可信区间：0.04，10.09）。刷牙频率不规则的儿童发生牙髓受累的可能性高 3.2 倍（COR = 3.21；95%可信区间：1.74-5.93）。
手指刷牙、刷牙频率不规则和刷牙时缺乏家长监督与 UDC 及其后果有关。
