Our aim was to investigate the relationship among the oral health-related quality of life, the sense of coherence (SOC), and socio-economic and demographic factors, oral behavioural variables and oral health variables. The sample of this study consisted of 4,039, 30-64-yr-old dentate adults (1,899 men and 2,140 women). The questionnaire and home interview included information about socio-economic and demographic factors, behavioural and attitudinal variables (such as oral health behaviours and oral health variables), the SOC (12-item) and the Oral Health Impact Profile scales (OHIP-14). Subjects with a strong or moderate SOC were found to have significantly fewer problems attributed to oral conditions (OHIP) than those with a weak SOC. The SOC was also associated with all of the subscales of the OHIP, and the association was most evident in psychological discomfort, psychological disability and handicap subscales. The SOC appears to be a determinant of the OHIP, independently of oral health, oral health behaviour and socio-economic factors. A psycho-social aspect is strongly embodied in the oral health-related quality of life of individuals.
This study assessed the independent and interactive associations between sense of coherence (SOC) and socio-economic status (SES) with oral health-related behaviours. Data from 5,399 dentate adults regarding their demographic characteristics, years of education, SOC score, and oral health-related behaviours were analysed. Household income was obtained from tax authorities. Logistic regression was used to test the adjusted association of SOC with each behaviour and to test the statistical interaction between each SES indicator and the SOC score. Subjects were 1.20 [95% confidence interval (95% CI): 1.11-1.28] and 1.22 (95% CI: 1.12-1.32) times more likely to visit dentists regularly for check-ups and to brush their teeth twice daily or more often, respectively, and were 1.11 (95% CI: 1.03-1.20) and 1.21 (95% CI: 1.12-1.32) times less likely to be daily smokers and to consume sugar-added products on a daily basis, respectively, for every unit increase in SOC score. The findings provide strong support for an association between higher levels of SOC and more favourable oral health-related behaviours, independently of current SES and demographic characteristics of the participants and across the four behaviours assessed. By contrast, the findings give limited support for the moderating role of SOC on the relationship between SES and oral health-related behaviours.
Our results suggest that a weak sense of coherence increases both the probability of having a poor level of oral hygiene and a frequency of toothbrushing of less than once a day. This and the theory concerning the development of SOC suggest that sense of coherence may be taken as a determinant of both the frequency and the quality of toothbrushing.
Oral bacteria DNA has been found in intracranial aneurysms (IA) and a high prevalence of periodontitis was reported in IA patients. We investigated whether periodontitis associates with IA formation and aneurysmal subarachnoid hemorrhage (aSAH). First, we compared in a case-control setting the prevalence of periodontal disease in IA patients (42 unruptured IA, 34 ruptured IA) and in age-and gender-matched controls (n = 70) from the same geographical area (Health 2000 Survey, BRIF8901). Next, we investigated whether periodontitis at baseline associated with aSAH in a 13-year follow-up study of 5170 Health 2000 Survey participants. Follow-up data was obtained from national hospital discharge and cause of death registries. Univariate analysis, logistic regression, and Cox-regression were used. Periodontitis (≥ 4mm gingival pocket) and severe periodontitis (≥ 6mm gingival pocket) were found in 92% and 49% of IA patients respectively and associated with IAs (OR 5.3, 95%CI 1.1-25.9, p < 0.000 and OR 6.3, 95%CI 1.3-31.4, p < 0.001, respectively). Gingival bleeding had an even stronger association, especially if detected in 4-6 teeth sextants (OR 34.4, 95%CI 4.2-281.3). Severe periodontitis in ≥ 3 teeth or gingival bleeding in 4-6 teeth sextants at baseline increased the risk of aSAH during follow-up (HR 22.5, 95%CI 3.6-139.5, p = 0.001 and HR 8.3, 95%CI 1.5-46.1, p = 0.015, respectively). Association of periodontitis and gingival bleeding with risk of IA development and aSAH was independent of gender, smoking status, hypertension, or alcohol abuse. Periodontitis and gingival bleeding associate with increased risk for IA formation and eventual aSAH. Further epidemiological and mechanistic studies are indicated.
The relationship between childhood SES and adult oral health-related behaviours was mainly mediated by adulthood SES, and to a much less extent by SOC. A stronger SOC was significantly associated with better adult oral health-related behaviours, after controlling for the effect of adulthood SES and demographic characteristics of the participants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
