目的比较朱拉隆功大学牙科学院有至少20颗天然牙（NT）和少于20颗天然牙的泰国老年牙科患者的口腔健康相关生活质量（OHRQoL），至少有4个后牙咬合对（POP）的患者之间研究背景泰国政府建议老年人应至少有20个NT和4个POP。材料和方法患者接受访谈，并使用口腔对日常表现的影响指数（OIDP）确定他们的OHRQoL。OIDP评分越高表明OHRQoL越差。结果NT小于20或POP小于4的受试者的OIDP评分显著高于NT至少20或POP至少4的受试者。此外，当我们逐个评估牙齿缺失时，我们发现至少23颗牙齿和少于23颗牙齿的受试者的OIDP评分之间的第一个和最后一个显著差异，结论泰国老年参与者至少20 NT或至少4 POP有更大的OHRQoL比那些小于20 NT或小于4 POP，在我们的研究样本中，我们观察到，5颗牙齿可能是一个重要的临床阈值泰国老年牙科患者的生活质量。
ObjectivesTo compare between the oral health-related quality of life (OHRQoL) of Thai elderly dental patients at the Faculty of Dentistry, Chulalongkorn University with at least 20 natural teeth (NT) and those with less than 20 NT, and between those with at least 4 posterior occluding pairs (POP) and those with less than 4 POP.BackgroundThai government recommended that elderly people should have at least 20 NT and 4 POP.Materials and methodsThe participants comprised 240 Thai elderly dental patients who were interviewed and had their OHRQoL determined using the Oral Impacts on Daily Performances Index (OIDP). Higher OIDP score indicates poorer OHRQoL. We counted the functional NT and POP in each participant.ResultsParticipants with less than 20 NT or less than 4 POP had significantly higher OIDP scores than those with at least 20 NT or at least 4 POP. Moreover, when we evaluated one by one tooth loss, we found the first and the last significant differences between the OIDP scores in the participants with at least 23 teeth and with less than 23 teeth, and those in the participants with at least 5 teeth and with less than 5 teeth, in consequently.ConclusionThai elderly participants with at least 20 NT or at least 4 POP had greater OHRQoL than those with less than 20 NT or less than 4 POP, and in our study sample, we observed that 5 teeth may be an important clinical threshold for Thai elderly dental patients' quality of life.
