The aim of this study was to compare the usefulness of two different questionnaires assessing oral health-related quality of life (OHRQoL) at the basic examination and after initial dental hygiene treatment (DHtx).
A total of 42 patients referred for periodontal treatment completed the Oral Health Impact Profile (OHIP-14) and the General Oral Health Assessment Index (GOHAI) at the basic periodontal examination. They underwent DHtx and completed the questionnaires once again after the treatment.
No statistically significant differences could be found between the two assessments, neither for the total scores nor for any of the separate items of the OHIP-14 or the GOHAI. However, the GOHAI questionnaire seems to result in a greater variety in the responses indicating that the floor effect is not as pronounced as for the OHIP-14. Those who had rated their oral health as good reported significantly better OHRQoL on both questionnaires. The same pattern was found for patients who reported that they were satisfied with their teeth. After DHtx and necessary extractions, there was a statistically significant correlation between the number of teeth and the total scores on both questionnaires. No other statistically significant correlations with periodontal variables could be found.
No statistically significant difference could be found after DHtx compared to before in regard to OHRQoL assessed with OHIP-14 and GOHAI. However, there was a greater variety in the responses with the GOHAI questionnaire; it may hereby be more useful for patients with periodontal disease.
本研究旨在比较两种不同问卷在基础检查和初始口腔卫生治疗（DHtx）后评估口腔健康相关生活质量（OHRQoL）的有用性。
共有 42 名因牙周治疗而转诊的患者在基础牙周检查时完成了口腔健康影响量表（OHIP-14）和一般口腔健康评估指数（GOHAI）的评估。他们接受了 DHtx 治疗，并在治疗后再次完成了这些问卷的评估。
在总评分和 OHIP-14 或 GOHAI 的任何单独项目中，两次评估之间均未发现统计学上的显著差异。然而，GOHAI 问卷似乎导致了更多的不同反应，表明其下限效应不如 OHIP-14 明显。那些将自己的口腔健康评为良好的人在两个问卷上的 OHRQoL 评分明显更高。对牙齿满意的患者也存在同样的模式。在 DHtx 和必要的拔牙后，两个问卷的总评分与牙齿数量之间存在统计学显著的相关性。未发现与牙周变量相关的其他统计学显著相关性。
与基础检查时相比，DHtx 后在 OHIP-14 和 GOHAI 评估的 OHRQoL 方面未发现统计学显著差异。然而，GOHAI 问卷的反应更为多样；因此，它可能对牙周病患者更有用。
