This study aimed to evaluate the effect of audiovisual motivation (AVM) and oral health education (OHE) on oral health (OH) and oral health-related quality of life (OHRQoL) among children at social homes.
This was a double-blinded cluster-randomised clinical trial. Subjects (n = 225) aged 4-14 years were recruited from social homes and randomly divided into 2 groups: control group (n = 100) and study group (n = 115); each was further divided into sub-groups: 4-6, 7-12 and > 12 years. Both groups were interviewed and examined to record DMFT/dmft (baseline and 12 months), plaque index (PI) and gingival index (GI) (baseline, 3, 6 and 12 months). The study group had multiple AVM and OHE sessions; the control group had no intervention.
Mean sample age was 9.1 ± 2.7 years. At 12 months, 4-6-year-olds had a significant improvement in PI for study and control groups (P < 0.001, P = 0.008 respectively), and GI was significantly improved in study group (P < 0.001). In 7-12-year-olds, a significant improvement in the PI, GI and dmft was found in study group (P < 0.001 for all), with an increase in DMFT in the control group (P < 0.001). For > 12 years, there was a significant improvement in PI (P = 0.002), GI (P = 0.043). There was significant improvement in OHRQoL in the study group only in these domains: bleeding when brushing teeth (P = 0.04) and presence of bad breath in the morning (P < 0.001).
There was a favourable effect of AVM and OHE on OH and OHRQoL in children aged 4-14 years at social homes after 12 months.
本研究旨在评估视听激励（AVM）和口腔健康教育（OHE）对社会福利院儿童口腔健康（OH）及口腔健康相关生活质量（OHRQoL）的影响。
这是一项双盲整群随机临床试验。从社会福利院招募4至14岁的受试者（n = 225），随机分为两组：对照组（n = 100）和研究组（n = 115）；每组再进一步分为子组：4至6岁、7至12岁和大于12岁。对两组进行访谈和检查，以记录DMFT/dmft（基线和12个月时）、菌斑指数（PI）和牙龈指数（GI）（基线、3个月、6个月和12个月时）。研究组进行多次AVM和OHE课程；对照组不进行干预。
样本平均年龄为9.1±2.7岁。在12个月时，4至6岁儿童中，研究组和对照组的PI均有显著改善（分别为P < 0.001，P = 0.008），研究组的GI有显著改善（P < 0.001）。在7至12岁儿童中，研究组的PI、GI和dmft均有显著改善（均为P < 0.001），对照组的DMFT增加（P < 0.001）。对于大于12岁的儿童，PI有显著改善（P = 0.002），GI有显著改善（P = 0.043）。仅在这些方面，研究组的OHRQoL有显著改善：刷牙时出血（P = 0.04）和早晨有口臭（P < 0.001）。
12个月后，AVM和OHE对社会福利院4至14岁儿童的OH和OHRQoL有积极影响。
