Abstract
OBJECTIVES
This study aimed to establish the validity—specifically, the sensitivity and specificity—of the screening questionnaire and diagnostic criteria for oral frailty proposed by the Korean Academy of Geriatric Dentistry (KAGD) among community-dwelling older adults.
METHODS
This study enrolled 100 participants. Among various definitions of oral frailty, this study used the criteria proposed by Tanaka as the reference test. The screening questionnaire consisted of 11 items for screening physical frailty, chewing ability, swallowing difficulties, oral dryness, and tongue and lip motor function. Each question had a different scoring weight, and if the total score was 1 or higher, an oral frailty diagnostic examination proposed by the KAGD would be recommended. The diagnostic test was the oral frailty diagnostic criteria proposed by the KAGD including 6 measures: chewing ability, occlusal force, tongue pressure, oral dryness, swallowing difficulty, and oral hygiene. If a participant exhibited 2 or more positive measures, this participant was classified as “oral frail.” The screening questionnaire was analyzed using a cut-off value of 1 or higher, while the diagnostic criteria utilized a cut-off of 2 or more positive measures. Sensitivity and specificity were calculated.
RESULTS
The screening questionnaire showed significant power for screening oral frailty (area under the receiver operating characteristic curve, 0.783; sensitivity, 87.8%; specificity, 52.5%). The diagnostic accuracy of the newly proposed diagnostic criteria was acceptable (sensitivity, 95.1%; specificity, 42.4%).
CONCLUSIONS
The newly proposed screening questionnaire and diagnostic criteria in Korea appear to be a useful tool to identify oral frailty in community-dwelling older adults.

Korean summary
본 연구는 지역사회에 거주하는 노인들의 구강 노쇠에 대한 선별검사 설문지와 진단 기준을 검증하는 것을 목표로 했습니다. 민감도와 특이도가 계산되었으며, 스크리닝 설문지는 구강 노쇠를 식별하는 데 상당한 힘을 보여주었고(민감도 87.8%, 특이도 52.5%), 진단 기준은 수용 가능한 정확도(민감도 95.1%, 특이도 42.4%)를 나타냈습니다. 연구 결과는 제안된 선별 설문지와 진단 기준이 한국 지역사회에 거주하는 노인들의 구강 노쇠를 식별하는 데 유용한 도구임을 시사합니다.
Key Message
This study aimed to validate a screening questionnaire and diagnostic criteria for oral frailty among older adults living in the community. Sensitivity and specificity were calculated, with the screening questionnaire demonstrating a significant power for identifying oral frailty (sensitivity 87.8%, specificity 52.5%) and the diagnostic criteria showing acceptable accuracy (sensitivity 95.1%, specificity 42.4%). The findings suggest that the proposed screening questionnaire and diagnostic criteria are valuable tools for identifying oral frailty in community-dwelling older adults in Korea.

Abstract
OBJECTIVES
Population aging is rapidly accelerating worldwide. Oral diseases related to aging are also on the rise. This study examined trends in the incidence of edentulism among the older Korean population using data from the Korean National Health Insurance Service (KNHIS).
METHODS
Data on older adults, aged ≥75 years of age, were obtained from the KNHIS for the period 2013-2018. Edentulism was defined as a treatment history of complete dentures in the KNHIS database. The exclusion criteria consisted of both disease codes and treatment codes related to conservative dental treatment, including periodontal and extraction treatment afterward. Crude incidence rates (CIRs) and age-standardized incidence rates (AIRs) with 95% confidence intervals were calculated and reported per 100,000 person-years by the direct method. Trends were tested by Cochrane Armitage models.
RESULTS
Statistically significant increasing trends in both CIRs and AIRs were found among the older Korean population registered in the KNHIS (CIRs, 707.92 to 895.92; AIRs, 705.11 to 889.68; p<0.01). The incidence tended to increase in both genders (p<0.01). Both CIRs and AIRs in specific regions also showed slight but significant annual increases except for Jeju Island (p<0.01 or <0.05). The incidence showed increasing trends (p<0.01) in all income quintiles apart from the highest quintile. The edentulism incidence was highest in the lowest income group (the first quintile).
CONCLUSIONS
Our data showed that the incidence of edentulism among the elderly showed an increasing trend from 2013 to 2018. This result provides a basis for future epidemiological studies on the incidence of edentulism in the older Korean population.
