This study evaluated the relationship between enrolment in a school-based oral health prevention program (SOHP) and: 1) children's dental health status and oral health-related quality of life (OHRQoL), and 2) mothers' oral health (OH) knowledge, attitude, practice, and OHRQoL.
This cross-sectional study, in the Kuwait Capital, included 440 primary school children aged 11 to 12 years and their mothers. Participants were classified into two groups: SOHP and non-SOHP. The SOHP group had been enrolled in the prevention program for at least 3 years: children had twice-a-year applications of fluoride varnish and fissure sealants if needed; mothers had, at least, one oral health education session. The non-SOHP group had negative consents and had not been exposed to the prevention program activities. Dental examinations were performed at schools using portable dental units. Caries experience was determined using the decayed (D/d), missing (M/m), and filled (F/f) teeth (T/t)/surface (S/s) indices. Children's OHRQoL was assessed using a self-administered validated Child Perceptions Questionnaire 11-14 (CPQ). Mothers' OH knowledge, attitude, practice, and OHRQoL were also assessed. After Bonferroni correction, a p-value of less than 0.05 was considered statistically significant for caries experience measures while a p-value of less than 0.013 was considered statistically significant for OHRQoL subscales and mothers' OH knowledge, attitude, practice, and OHRQoL.
Mean (SD) DT/dt, DMFT/dmft and DMFS/dmfs were 1.41 (1.66), 2.35 (2.33), and 4.41 (5.86) for SOHP children, respectively. For non-SOHP children, the means were 2.61 (2.63), 3.56 (3.05), and 7.24 (7.78), respectively. The difference between the SOHP and non-SOHP was statistically significant (p < 0.001). Children enrolled in the program had a higher number of sealed and restored teeth. No significant differences were found in CPQ scores or subscale scores between the two groups. No significant difference in mothers' OH knowledge, attitude, practices or OHRQoL was found between SOHP and non-SOHP groups (P > 0.013).
Enrolment in the SOHP prevention services was associated with a positive impact on children's caries level with no significant impact on mothers' knowledge, attitude, practice, or OHRQoL.
本研究评估了参加基于学校的口腔健康预防计划（SOHP）与以下方面之间的关系：1）儿童的口腔健康状况和口腔健康相关生活质量（OHRQoL），以及 2）母亲的口腔健康（OH）知识、态度、实践和 OHRQoL。
本横断面研究在科威特首都进行，纳入了 440 名 11 至 12 岁的小学生及其母亲。参与者分为两组：SOHP 和非 SOHP。SOHP 组至少已参加该预防计划 3 年：儿童每年接受两次氟化物涂料和窝沟封闭剂应用，如果需要的话；母亲至少接受过一次口腔健康教育课程。非 SOHP 组拒绝参加且未接触预防计划活动。在学校使用便携式牙科设备进行口腔检查。采用龋失补（D/d）、龋失补牙面数（DMFT/dmft）和龋失补牙面数（DMFS/dmfs）指数来确定龋齿患病情况。使用经过验证的儿童感知问卷 11-14（CPQ）评估儿童的口腔健康相关生活质量。还评估了母亲的口腔健康知识、态度、实践和口腔健康相关生活质量。经 Bonferroni 校正后，龋齿患病情况指标的 p 值小于 0.05 被认为具有统计学意义，而 OHRQoL 分量表和母亲的口腔健康知识、态度、实践和 OHRQoL 的 p 值小于 0.013 被认为具有统计学意义。
SOHP 儿童的平均（标准差）DT/dt、DMFT/dmft 和 DMFS/dmfs 分别为 1.41（1.66）、2.35（2.33）和 4.41（5.86）。非 SOHP 儿童的平均值分别为 2.61（2.63）、3.56（3.05）和 7.24（7.78）。SOHP 和非 SOHP 之间的差异具有统计学意义（p<0.001）。参加该计划的儿童有更多的封闭和修复牙齿。两组间 CPQ 评分或分量表评分无显著差异。SOHP 和非 SOHP 组之间的母亲口腔健康知识、态度、实践或口腔健康相关生活质量无显著差异（P>0.013）。
参加 SOHP 预防服务与儿童龋齿水平的积极影响相关，而对母亲的知识、态度、实践或口腔健康相关生活质量无显著影响。
