“…34 As previous studies have indicated the need to divide into those with 20 or more remaining teeth and those with fewer than 20 remaining teeth to accurately assess the effects of interdental cleaning devices among in older people, we conducted our analysis in these two groups. 35 In this study, there were more participants with 20 or more teeth than those with 20 or fewer teeth. Furthermore, the effective of dental floss is higher in the group with 20 or more teeth.…”

“…The reason for this is likely that dental literacy and knowledge are disseminated more through the media, and thus the significance of oral health is conveyed accordingly 34 . As previous studies have indicated the need to divide into those with 20 or more remaining teeth and those with fewer than 20 remaining teeth to accurately assess the effects of interdental cleaning devices among in older people, we conducted our analysis in these two groups 35 . In this study, there were more participants with 20 or more teeth than those with 20 or fewer teeth.…”

ObjectiveTo assess the association between the usage of interdental cleaning and periodontal status among older people in Korea.BackgroundIn order to maintain oral health in older people, it is very important to use interdental cleaning devices. However, there is a lack of research on periodontal status and interdental cleaning device use in older people.MethodsThis study used data collected from the 7th National Health Nutrition Survey (KNHANES VII: 2016–2018). A total of 3426 older people adults aged 65 years or older were selected from 16 489 participants. Data on sociodemographic status (sex, age, level of education, income, residential area), personal health practice (subjective health status, smoking, physical activity, hypertension, and diabetes mellitus), oral health practice (subjective oral health status, tooth brushing frequency, dental visits, and chewing problem), the number of teeth and periodontitis were collected. Periodontitis was defined as having a World Health Organisation community periodontal index (CPI) code greater than or equal to three, and severe periodontitis was defined as a CPI code 4. Participants having a CPI code of 3 or 4 were considered to have periodontal disease in this study. Logistic regression analysis investigated the association between interdental cleaning devices usage and periodontitis controlling the confounding factors.ResultsThose who do not use dental floss had a higher rate of periodontal disease (AOR = 1.47, 95% confidence interval [CI]: 1.05 to 2.1). However, there were no significant differences by interdental brush use. In those with 20 or more teeth, non‐users of dental floss had a higher risk of periodontitis in all models. Conversely, in those with fewer than 20 teeth, no significant differences were observed.ConclusionsOlder people with mostly intact dentitions have better periodontal health if they clean between their teeth.

“…The subjects were divided into two groups based on the number of remaining teeth (≥20, <20) according to previously described reports. 33,34 Patient demographic and clinical characteristics were compared between groups, and mean values, standard deviations, medians, 25-75 percentiles, and p-values were calculated. We used the χ 2 -test or Fisher's exact test for categorical values, and used Student's t test or the Mann-Whitney U test for continuous values.…”

ObjectivesThis study examined the association between the number of remaining teeth and the incidence of postoperative respiratory complications in patients undergoing heart valve surgery.MethodsWe retrospectively enrolled 157 patients who underwent heart valve surgery between April 2010 and March 2019. Data on patient characteristics including systemic and oral conditions were extracted and postoperative respiratory complications were set as outcomes. Patients were divided into two groups according to the number of remaining teeth (≥20, <20). After adjusting for confounding factors with propensity scoring, logistic regression analysis was performed to examine the association of remaining teeth number with the incidence of postoperative respiratory complications. In addition, subgroup analysis was performed by stratifying the data into quintiles based on the propensity score.ResultsUnivariate analysis showed significant differences between the two groups in factors, including age, past cardiac surgery experience, New York Heart Association functional classification class IV, denture use, tooth extraction before surgery, occlusal support, and periodontitis. Logistic regression analysis showed that patients with <20 remaining teeth had a significantly higher incidence of postoperative respiratory complications than those with ≥20 remaining teeth, with an odds ratio of 29.800 (p = 0.004). Subgroup analysis showed that the odds ratio for the patients with <20 remaining teeth was 9.000 (p = 0.038).ConclusionsThe results suggest that heart valve surgery patients shall get attention on oral disease prevention by dental care practitioners to maintain a sufficient number of teeth for the prevention of postoperative respiratory complications.

“…In contrast to randomized clinical trials, cross‐sectional (Cepeda et al, 2017; Kim & Han, 2021; S. J. Kim, Lee, et al, 2022; Y. J. Kim, Gil, et al, 2022; Lang et al, 1995; Lee et al, 2018; Marchesan et al, 2018) and cohort studies (Chaffee et al, 2020; Kressin et al, 2003; Marchesan et al, 2020) predominantly reported that both flossing and interdental brushing in addition to toothbrushing were associated with lower levels of periodontitis, caries and tooth loss among different populations with a predominantly wide age range (19+/30+ years). In three repeated cross‐sectional studies, IDA use explained a significant portion of explainable changes in the mean probing depth (PD), the number of caries‐free healthy surfaces and the number of teeth (Pitchika et al, 2021).…”

AimTo estimate association between the use of interdental cleaning aids (IDAs) and type on 7‐year follow‐up levels of interdental plaque, interdental gingival inflammation, interdental periodontitis severity, the number of interdental sound surfaces and the number of missing teeth in a population‐based cohort study.Materials and MethodsWe used 7‐year follow‐up data of 2224 participants from the Study of Health in Pomerania (SHIP‐TREND). We applied generalized linear and ordinal logistic models, adjusting for confounding and selection bias using inverse probability treatment weighting and multiple imputation.ResultsFlossers were 32% less likely to have higher interdental plaque (iPlaque) levels than non‐users of IDAs (odds ratio [OR] = 0.68; 95% confidence interval [CI]: 0.50–0.94); flossing resulted in 5% lower means of iPlaque. Effects on interdental bleeding on probing (iBOP), mean interdental probing depths and mean interdental clinical attachment levels were direction‐consistent but statistically non‐significant. Interdental brushing was associated with lower follow‐up levels for interdental plaque (OR = 0.73; 95% CI: 0.57–0.93) and iBOP (OR = 0.69; 95% CI: 0.53–0.89). IDAs were more effective in reducing iPlaque in participants with periodontitis, whereas iBOP reduction was more pronounced in participants with no or mild periodontitis. The analyses did not suggest that the use of IDAs affected caries. Finally, applying change score analyses, flossing reduced tooth loss incidence (incidence rate ratio [IRR] = 0.71) compared with non‐users of IDAs.ConclusionsRecommending flossing and interdental brushing in dental practices represents an approach to the prevention of gingivitis and consequently periodontitis.
