Zusammenfassung: | Objectives: The aim of this study was to identify the risk factors for tooth loss over three years, accord-ing to the number of pre-existing teeth, in middle and old aged people in a rural area.
Methods: This was a 3-year follow-up study including participants from KoGES-ARIRANG. Eight-hundred and fifty-five participants took part in both initial and follow-up oral examinations and surveys, conducted between 2010 and 2016. The number of existing teeth was determined through oral exami-nation, and the subjects` sociodemographic characteristics, subjective periodontal statuses, and oral health behaviors were identified through oral questionnaires via 1:1 interviews. Chi-square analysis was used to compare tooth loss in participants with less than 20 pre-existing teeth to tooth loss in those with 20 or more pre-existing teeth. Multivariate logistic regression analyses were used to identify risk factors for tooth loss.
Results: Four-hundred and thirty-nine (51.4%) subjects lost more than one tooth over three years. After adjusting for demographic characteristics, subjective periodontal statuses, and oral health behaviors in subjects with 20 or more pre-existing teeth, the odds for tooth loss were as follows: 2.11 (1.42-3.14) times higher in people aged over 65 years compared to less than 65 years, 1.59 (1.06-2.38) times high-er in those with a low (below elementary school) compared to high educational level, and 2.01 (1.33-3.02) times higher in those with a severe compared to normal subjective periodontal status.
Conclusions: The risk of tooth loss was different in subjects with less than 20 pre-existing teeth com-pared to those with 20 or more pre-existing teeth. Therefore, the approach to prevent tooth loss should be different depending on the number of teeth present. |
