Abstract

Aims: To investigate and describe the concordance between salivary flow rates and xerostomia among older dependent adults, describe the association between medication use and dry mouth, and describe the impact of dry mouth on oral health-related quality of life (OHRQoL).

Methods: A clinical examination survey was conducted with 50 older adults residing in residential care facilities in Dunedin, New Zealand. Xerostomia was measured using the five-item Summated Xerostomia Inventory-Dutch Version (SXI-D), and the unstimulated salivary flow rate was also measured. The clinical manifestations of oral dryness were evaluated using the Clinical Oral Dryness Scoring (CODS) scale. Medications were recorded.

Results: Participants ranged in age from 65 to 99 years (mean 83.0, SD 9.1). The prevalence of xerostomia was 34.8%, while salivary gland hypofunction (SGH) was present in 26.1%. Only 13.0% of participants had both conditions, and 52.2% had neither. A weak negative correlation was observed between the SXI-D score and salivary flow rate (r = -0.20), while a moderate positive correlation was found between the SXI-D and the CODS scale (r = 0.55). Additionally, the CODS scale showed a moderate negative correlation with the salivary flow rate (r = -0.47).

Conclusion: Dry mouth is common among older adults in residential care, but the relationship between its signs and symptoms is complex. Salivary hypofunction data alone do not fully capture the experience of oral dryness, emphasising the need for a more comprehensive approach to diagnosis and treatment.

老年人在住宿护理中的口干测量。

目的：研究和描述老年依赖者唾液流率与口干症之间的一致性，描述药物使用与口干之间的关系，以及描述口干对口腔健康相关生活质量（OHRQoL）的影响。方法：对居住在新西兰达尼丁养老院的50名老年人进行临床检查调查。采用荷兰版五项口腔干燥量表（SXI-D）测量口腔干燥，并测量非刺激唾液流率。采用临床口腔干燥评分（CODS）量表对口腔干燥的临床表现进行评价。记录用药情况。结果：参与者年龄从65岁到99岁不等（平均83.0岁，SD 9.1）。口干的患病率为34.8%，而涎腺功能减退（SGH）的患病率为26.1%。只有13.0%的参与者两者都有，52.2%的参与者两者都没有。SXI-D评分与唾液流率呈弱负相关（r = -0.20）， SXI-D评分与CODS量表呈中度正相关（r = 0.55）。此外，CODS量表与唾液流量呈中度负相关（r = -0.47）。结论：口干在住院老年人中较为常见，但其体征和症状之间的关系较为复杂。唾液功能减退的数据本身并不能完全捕捉到口腔干燥的经验，强调需要更全面的诊断和治疗方法。

期刊介绍： The ultimate aim of Gerodontology is to improve the quality of life and oral health of older people. The boundaries of most conventional dental specialties must be repeatedly crossed to provide optimal dental care for older people. In addition, management of other health problems impacts on dental care and clinicians need knowledge in these numerous overlapping areas. Bringing together these diverse topics within one journal serves clinicians who are seeking to read and to publish papers across a broad spectrum of specialties. This journal provides the juxtaposition of papers from traditional specialties but which share this patient-centred interest, providing a synergy that serves progress in the subject of gerodontology.
