In the 21st century, dental caries remains a global burden, particularly severely affecting the growth and quality of life of 12-year-old children. Fortunately, pit and fissure sealing (PFS) procedures can effectively prevent molars from caries. Hence, this study focused on the relationship between PFS and oral epidemiological factors in 12-year-old children.
A cross-sectional survey was conducted in 12-year-old children from 11 cities in Zhejiang Province. Their dental conditions were collected through questionnaires, as well as basic information such as relevant family information, oral health knowledge and behavior. Then, logistic regression analysis was used to identify the influencing factors associated with PFS.
A total of 1204 children were included, with 252 in the PFS group and 952 in the non-PFS group. There were significant differences between the two groups in terms of decayed, missing and filled teeth (DMFT) score, first permanent molar DMFT score, residential area, educational level of parents, tooth-brushing frequency, use of dental floss, oral examination in a medical institution, having taken courses on oral health care, as well as having knowledge that tooth brushing could effectively prevent gingival inflammation, PFS could protect teeth, and oral disease may affect general health. According to further logistic regression analysis, the independent factors influencing PFS included use of dental floss [odds ratios (OR) = 1.672, 95% confidence intervals (CI) = 1.235-2.263, P = 0.001], having taken courses on oral health care (OR = 0.713, 95% CI = 0.515-0.988, P = 0.042), having knowledge that tooth brushing is effective in preventing gingival inflammation (OR = 0.627, 95% CI = 0.389-0.987, P = 0.044) and having knowledge that PFS can protect teeth (OR = 0.589, 95% CI = 0.438-0.791, P < 0.001).
PFS can reduce the mean DMFT score of 12-year-old children. Independent influencing factors of PFS consist of use of dental floss, having taken courses on oral health care, oral health behavior and knowledge level.
在 21 世纪，龋齿仍然是一个全球性的负担，尤其严重影响了 12 岁儿童的生长和生活质量。幸运的是，窝沟封闭（PFS）程序可以有效地预防磨牙龋齿。因此，本研究关注的是 12 岁儿童的 PFS 与口腔流行病学因素之间的关系。
对浙江省 11 个城市的 12 岁儿童进行横断面调查。通过问卷调查收集他们的口腔状况，以及相关家庭信息、口腔健康知识和行为等基本信息。然后，采用 logistic 回归分析识别与 PFS 相关的影响因素。
共纳入 1204 名儿童，其中 PFS 组 252 名，非 PFS 组 952 名。两组儿童在患龋率（DMFT）评分、第一恒磨牙 DMFT 评分、居住地、父母受教育程度、刷牙频率、使用牙线、医疗机构口腔检查、接受口腔保健课程、知晓刷牙可有效预防牙龈炎、PFS 可保护牙齿、口腔疾病可能影响全身健康等方面存在显著差异。进一步的 logistic 回归分析表明，影响 PFS 的独立因素包括使用牙线（比值比[OR] = 1.672，95%置信区间[CI] = 1.235-2.263，P = 0.001）、接受过口腔保健课程（OR = 0.713，95% CI = 0.515-0.988，P = 0.042）、知晓刷牙能有效预防牙龈炎（OR = 0.627，95% CI = 0.389-0.987，P = 0.044）和知晓 PFS 可保护牙齿（OR = 0.589，95% CI = 0.438-0.791，P < 0.001）。
PFS 可降低 12 岁儿童的平均 DMFT 评分。PFS 的独立影响因素包括使用牙线、接受过口腔保健课程、口腔健康行为和知识水平。
