Generic and condition-specific (CS) oral-health-related quality-of-life (OHRQoL) instruments assess the impacts of general oral conditions and specific oral diseases. Focusing schoolchildren from Arusha and Dar es Salaam, in Tanzania, this study compared the discriminative ability of the generic Child OIDP with respect to dental caries and periodontal problems across the study sites. Secondly, the discriminative ability of the generic-and the CS Child OIDP attributed to dental caries, periodontal problems and malocclusion was compared with respect to various oral conditions as part of a construct validation.
In Arusha, 1077 school children (mean age 14.9 years, range 12-17 years) and 1601 school children in Dar es Salaam (mean age 13.0 years, range 12-14 years) underwent oral clinical examinations and completed the Kiswahili version of the generic and CS Child-OIDP inventories. The discriminative ability was assessed as differences in overall mean and prevalence scores between groups, corresponding effect sizes and odd ratios, OR.
The differences in the prevalence scores and the overall mean generic Child-OIDP scores were significant between the groups with (DMFT > 0) and without (DMFT = 0) caries experience and with (simplified oral hygiene index [OHI-S] > 1) and without periodontal problems (OHI-S ≤ 1) in Arusha and Dar es Salaam. In Dar es Salaam, differences in the generic and CS Child-OIDP scores were observed between the groups with and without dental caries, differences in the generic Child-OIDP scores were observed between the groups with and without periodontal problems, and differences in the CS Child-OIDP scores were observed between malocclusion groups. The adjusted OR for the association between dental caries and the CS Child-OIDP score attributed to dental caries was 5.4. The adjusted OR for the association between malocclusion and CS Child-OIDP attributed to malocclusion varied from 8.8 to 2.5.
The generic Child-OIDP discriminated equally well between children with and without dental caries and periodontal problems across socio-culturally different study sites. Compared with its generic form, the CS Child-OIDP discriminated most strongly between children with and without dental caries and malocclusion. The CS Child OIDP attributed to dental caries and malocclusion seems to be better suited to support clinical indicators when estimating oral health needs among school children in Tanzania.
通用和特定于条件的（CS）口腔健康相关生活质量（OHRQoL）量表评估一般口腔状况和特定口腔疾病的影响。本研究以坦桑尼亚阿鲁沙和达累斯萨拉姆的学童为研究对象，比较了通用儿童口腔影响生活质量调查问卷（Child OIDP）在研究地点对龋齿和牙周问题的区分能力。其次，比较了通用和 CS 儿童 OIDP 对龋齿、牙周问题和错颌畸形的区分能力，以评估各种口腔状况的结构效度。
在阿鲁沙，1077 名学生（平均年龄 14.9 岁，范围 12-17 岁）和达累斯萨拉姆的 1601 名学生（平均年龄 13.0 岁，范围 12-14 岁）接受了口腔临床检查，并完成了斯瓦希里语版通用和 CS 儿童 OIDP 量表。区分能力评估为组间总均值和患病率评分差异、相应的效应大小和比值比（OR）。
在阿鲁沙和达累斯萨拉姆，有（DMFT>0）和无（DMFT=0）龋齿史以及有（简化口腔卫生指数[OHI-S]>1）和无牙周问题（OHI-S≤1）的组间，通用儿童 OIDP 总均值和患病率评分差异具有统计学意义。在达累斯萨拉姆，有和无龋齿的组间通用和 CS 儿童 OIDP 评分差异、有和无牙周问题的组间通用儿童 OIDP 评分差异以及错颌畸形组间 CS 儿童 OIDP 评分差异均具有统计学意义。龋齿与 CS 儿童 OIDP 评分归因于龋齿的关联的调整比值比（OR）为 5.4。错颌与 CS 儿童 OIDP 评分归因于错颌的关联的调整 OR 从 8.8 到 2.5 不等。
通用儿童 OIDP 在社会文化不同的研究地点之间，能够很好地区分有和无龋齿和牙周问题的儿童。与通用形式相比，CS 儿童 OIDP 更能区分有和无龋齿和错颌的儿童。CS 儿童 OIDP 评分归因于龋齿和错颌，似乎更适合支持临床指标，以评估坦桑尼亚学童的口腔健康需求。
