Objectives To compare between the oral health‐related quality of life ( OHRQ oL) 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 . Background Thai government recommended that elderly people should have at least 20 NT and 4 POP . Materials and methods The participants comprised 240 Thai elderly dental patients who were interviewed and had their OHRQ oL determined using the Oral Impacts on Daily Performances Index ( OIDP ). Higher OIDP score indicates poorer OHRQ oL. We counted the functional NT and POP in each participant. Results Participants 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. Conclusion Thai elderly participants with at least 20 NT or at least 4 POP had greater OHRQ oL 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.
