高齢者医療専門病院における高齢入院患者の有する残根歯の現状と年次推移に関する報告 Current Situation and Annual Changes in Stumps of Teeth among Older Inpatients in a Geriatric Hospital 中野, 有生 Nakano, Yu 30253462 松山, 美和 マツヤマ, ミワ Matsuyama, Miwa 松山 マツヤマ Matsuyama 美和 ミワ Miwa 80585026 渡辺, 朱理 ワタナベ, アカリ Watanabe, Akari 渡辺 ワタナベ Watanabe 朱理 アカリ Akari 70189801 日野出, 大輔 ヒノデ, ダイスケ Hinode, Daisuke 日野出 ヒノデ Hinode 大輔 ダイスケ Daisuke open access 残根歯 高齢者 入院患者 保有率 年次推移 Stumps of teeth Older Hospitalized patients Prevalence rate Annual change 要介護高齢者の口腔の状態は多く報告されているが，残根歯の状況に関してはほとんど報告はない．そこで，高齢入院患者の有する残根歯の現状と年次推移について調査した． 対象は65歳以上の入院患者で，5つの期間（2013～2021年の隔年上半期）の歯科衛生士による口腔衛生管理の受療者とした．歯科診療録から現在歯および残根歯に関する情報を収集し，平均現在歯数，1歯以上の残根歯を有する者の割合，1歯以上の残根歯を有する者（以下，残根歯保有者）1人あたりの平均残根歯数，残根歯の部位別・歯種別割合，残根歯の未処置率を算出し，5期間の群間比較を実施した． 全対象は787例であった．平均現在歯数は13.2±10.1本，残根歯保有者は787例中315例，40.0%であり，残根歯保有者1人あたりの平均残根歯数は4.0±3.6本であった．残根歯の部位は上顎が下顎より多く，歯種は切歯が最も多く，大臼歯が最も少なかった．残根歯未処置率は97.9%で，ほとんどが未処置であった．1残根歯保有者の割合は5つの期間に有意差は認められず，顕著な年次推移は認められなかった． 高齢入院患者は残根歯を多く有しており，残根歯未処置率も高かった．高齢入院患者の口腔内環境改善のためには，残根歯の処置も含めた口腔健康管理が必要である． The oral health status of older patients requiring long-term care has been widely reported. However, while there are reports on stumps of teeth in outpatients, there are none on stumps in older hospitalized patients. Therefore, we investigated the current situation and annual changes in stumps of teeth in such patients. The participants were inpatients aged ≥ 65 years who received oral hygiene care from a dental hygienist five successive times (the first half of every other year from 2013 to 2021). Data on present teeth and stumps of teeth were collected from dental examination records. The mean number of present teeth, prevalence and mean number of stumps of teeth, percentage of stumps of teeth by site and tooth type, and percentage of untreated stumps of teeth were calculated and compared among the five care-receiving times. A total of 787 participants were included in the study for the entire period. The average number of present teeth was 13.2±10.1, 315 participants (40.0%) had one or more remaining root teeth, and the average number of remaining root teeth per patient was 4.0±3.6. There were more stumps of teeth in the upper compared with lower jaw. Regarding tooth types, incisors were most common, and molars were least common. The rate of untreated stumps of teeth was 97.9%, indicating that most stumps were untreated. There were no significant differences in any survey items when comparing the participants over the five periods, and no significant annual changes were observed. Older hospitalized patients had more stumps of teeth and a higher rate of untreated stumps. This was considered to be due to a worsening general condition and decreased independence in daily life. 日本口腔衛生学会 2025 jpn journal article VoR 446493 https://tokushima-u.repo.nii.ac.jp/records/2013394 https://doi.org/10.5834/jdh.75.1_15 10.5834/jdh.75.1_15 00232831 21897379 AN00081407 口腔衛生学会雑誌 Journal of Dental Health 75 1 15 21 https://tokushima-u.repo.nii.ac.jp/record/2013394/files/jdh_75_1_15.pdf application/pdf 1.4 MB 2025-08-08
