Purpose: Denture loss is still being reported as a problem in geriatric facilities, although losses seem less frequent than in the last decade. However, there have been no reports that have examined recent losses of dentures in detail. The aim of this study was to clarify the actual situation of recent denture loss, together with the denture loss rate in Japan. Materials and methods: This retrospective study investigated the number of cases of denture loss, the denture loss rate for denture wearers, and the details of losses in geriatric facilities during the 1-year period from 1 April 2020 to 31 March 2021. Results: Eleven special elderly nursing homes and four group homes participated in this research. The number of residents from each was 315 and 40 and the number of denture wearers was 165 and 33, respectively (p < 0.001). The loss of dentures was found in one case from a special elderly nursing home and in one case from a group home. The loss rate for denture wearers was 1.01% in total, with 0.61% for special elderly nursing homes and 3.03% for group homes, with no significant differences between the two types of facilities. Conclusion: In geriatric facilities in Japan, the current 1-year denture loss rate for denture wearers was 1.01%. This seems to represent a considerable decrease when compared with the previous report. Further, proper denture management and staff efforts appear to have contributed to a reduction in denture loss against a background of promoting oral healthcare.
尽管假牙丢失的情况似乎比过去十年更为少见，但在老年护理机构中，假牙丢失仍是一个问题。然而，尚无报告对近期假牙丢失情况进行详细调查。本研究旨在阐明日本近期假牙丢失的实际情况以及假牙丢失率。材料与方法：本回顾性研究调查了2020年4月1日至2021年3月31日这1年期间老年护理机构中假牙丢失的病例数、假牙佩戴者的假牙丢失率以及丢失的具体情况。结果：11家特殊养老院和4家集体之家参与了本研究。每家机构的居民人数分别为315人和40人，假牙佩戴者人数分别为165人和33人（p < 0.001）。在1家特殊养老院和1家集体之家中各发现1例假牙丢失。假牙佩戴者的总丢失率为1.01%，其中特殊养老院为0.61%，集体之家为3.03%，两类机构之间无显著差异。结论：在日本的老年护理机构中，目前假牙佩戴者1年的假牙丢失率为1.01%。与之前的报告相比，这似乎有了显著下降。此外，在促进口腔保健的背景下，适当的假牙管理和工作人员的努力似乎有助于减少假牙丢失情况。
