    Self-perceived oral health among 19-year-olds in a Swedish County - A comparative study between 2004 and 20112016In: Swedish Dental Journal, ISSN 0347-9994, Vol. 40, no 1, 53-65 p.Article in journal (Refereed)
    Abstract [en]

    For decades, Swedish dental professionals have collected clinical epidemiological data from the dental records. To supplement the epidemiology, Ostergotland County Council decided to examine patient perceptions of oral health: self-rated knowledge, self-perceived oral health, and opinions about oral health. The aim was to compare self-perceived oral health among 19-year-olds to determine differences between genders, various municipalities and between 2004 and 2011. This study analysed the responses from two cross-sectional surveys of the entire population of 19-year-olds in Ostergotland County, Sweden, performed in 2004 and 2011. Of the 2,413 (53 %) (50 % men, 50 % women) 19-year-olds who responded to the questionnaire in 2004 and the 3,803 (67 %) (50 % men, 50 % women) in 2011, most 19-year-olds (88.1 % [2004] and 87.5 % [am]) reported satisfaction with their oral health. Around half of the respondents rated their knowledge on periodontitis as low. Boys rated their knowledge about avoiding periodontitis higher than girls (p<0.05 in 2004 and p<0.001 in 2011). In 2004, 84.7 % reported shooting pain. In 2011 that figure was 83.7 %. The respondents expressed some uncertainty about the benefits of fluoride toothpaste (7.5 % in 2004 and 9.3 % in 2011), especially the boys (10.3 % in 2004 and 10.5 % in 2011). Girls reported both a higher social impact and greater concern about aesthetics related to their oral health. They also reported headache (27.5 %) nearly twice as often as boys (14.2 %) (p>0.001). Responses between the municipalities did not differ, with the exception of items regarding periodontitis. Thus, this study found indications that perceptions of oral health and knowledge in Ostergotland County complied with Swedish Dental Act. The study also found patient perceptions of oral health among 19-year-olds to be good.

    Long-term healthy lifestyle patterns and tooth loss studied in a Swedish cohort of middle-aged and older people2015In: International Journal of Dental Hygiene, ISSN 1601-5029, E-ISSN 1601-5037, Vol. 13, no 4, 292-300 p.Article in journal (Refereed)
    Abstract [en]

    The promotion of a healthy lifestyle has become an issue of public health importance in the context of ageing populations and increasing prevalence of chronic diseases. Objective(i) To estimate changes in use of fluoridated tooth paste, use of tooth picks, smoking and alcohol consumption and (ii) to examine whether experience with incident or prevalent tooth loss predict healthy lifestyle transitions from age 50 to 70. MethodIn 1992, 6346 individuals born in 1942 agreed to participate in a prospective cohort study and 3585 completed follow-up questionnaires in 1997, 2002, 2007 and 2012. Statistical analyses were conducted by chi-square statistics, Cochrans Q and logistic regression. ResultsIn total, 15.7% and 74.0% reported incident (tooth loss only in 2012) and prevalent tooth loss (tooth loss in 1992 and 2012). Significant differences occurred between the 1992 and 2012 prevalence of using toothpicks (from 48.3% to 69.1%), smoking (from 26.9% to 10.1%) and alcohol consumption (from 41.5% to 50.5%), 29% and 15.6% increased use of toothpicks and alcohol consumption, whereas 15.5% stopped daily smoking. Increased use of fluoridated tooth paste, smoking cessation and failure to increase use of toothpicks was associated with prevalent tooth loss between age 50 and 70. ConclusionThis study revealed positive and negative trends in oral health behaviours over a 20-year period in persons aged 50 at baseline. Mixed support was obtained for the assumption that oral health promoting lifestyle transitions follow experience with tooth loss. Older people with tooth loss experience could benefit from targeted counselling aimed at coping with oral diseases.

    Does different wording of a global oral health question provide different results?2015In: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 73, no 4, 250-257 p.Article in journal (Refereed)
    Abstract [en]

    Objective. Focusing on 70-year-old adults in Sweden and guided by the conceptual framework of International Classification of Impairments, Disabilities and Handicaps (ICIDH), the purpose of this study was to examine the extent to which socio-demographic characteristics, self-reported oral disease and social/psychological/physical oral health outcome variables are associated with two global measures of self-assessed satisfaction with oral health in Swedish 70-year-olds and if there is a degree of discordance between these global questions. Background. It has become an important task to create a simple way to measure self-perceived oral health. In these attempts to find practical ways to measure health, the global oral health question is a possible tool to measure self-rated oral health, but there is limited knowledge about how important the wording of this question is. Materials and methods. In 2012, a questionnaire was mailed to all persons born in 1942 in two Swedish counties, Orebro (T) and Ostergotland (E). The total population of 70-year-olds amounted to 7889. Bivariate analyses were conducted by cross-tabulation and Chi-square statistics. Multivariate analyses were conducted using binary multiple logistic regression. Results. The two global oral health question of 70-year-olds in Sweden was mainly explained by the number of teeth (OR = 5.6 and 5.2), chewing capacity (OR = 6.9 and 4.2), satisfaction with dental appearance (OR = 19.8 and 17.3) and Oral Impact on Daily Performance (OIDP) (OR = 3.5 and 3.9). Conclusion. Regardless of the wording, it seems that the concept of a global oral health question has the same main determinants.

    Self-perceived taste disturbance: a 20-year prospective study of a Swedish 1942 birth cohort2017In: Gerodontology, ISSN 0734-0664, E-ISSN 1741-2358, Vol. 34, no 2, 180-186 p.Article in journal (Refereed)
    Abstract [en]

    Objectives: The aim of this study was to assess the impact of dental care factors, general health factors and socio-economic factors on perceived taste disturbance (PTD) over time and to assess the stability of or change in PTD in a panel of individuals as they progressed from middle age (50 years) to early old age (70 years). Materials and methods: Data collection was conducted from a cohort study beginning in 1992, when the participants were 50 years old, and again 5, 10, 15 and 20 years later. Stability and change in PTD were described using cross-tabulation. Perceived taste disturbance over the 20-year survey period was modelled using the generalised estimating equation (GEE). Results: The prevalence of PTD during a 5-year period found in this study ranged from 2.4 to 2.9%, the latter in individuals between 60 and 70 years of age. Women generally had PTD more often than men. The longitudinal analysis showed that problems with bad breath (OR = 3.6), blisters (OR = 3.4), burning mouth (OR = 3.4) and self-perceived health (OR = 2.7) were the most important factors explaining PTD. Conclusions: This study showed that PTD does not increase between 50 and 70 years of age in ordinary community-living individuals. There were no long-term impacts on PTD over time from socio-economic factors, and over time, there were a limited number of factors contributing to the effect. Bad breath, blisters, burning mouth and self-perceived health are important factors for the dentist to discuss with the patient in the case of PTD.

    Satisfaction with dental care and life-course predictors: A 20-year prospective study of a Swedish 1942 birth cohort?2016In: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 74, no 3, 194-201 p.Article in journal (Refereed)
    Abstract [en]

    Objectives: The aim was to assess the impact of care experience, health factors and socioeconomic factors on satisfaction with dental care across time and to assess the stability or change in levels of self-reported satisfaction with dental care in individuals as they progress from middle age to early old age.Materials and methods: The present work is based on five separate data collections from a cohort study with 3585 individuals responding in all years of the survey. Data collection was conducted in 1992 when the subjects were 50 years of age and again 5, 10, 15 and 20 years later. Absolute stability in satisfaction with dental care was assessed by calculating the proportion of individuals who maintained their position in the same category from one survey period to another. Changes across time were tested using Cochrans Q test. Satisfaction with dental care across the 20-year survey period was modeled using the generalized estimating equation (GEE).Results and conclusion: The result showed that 85% of women and 83% of men remained satisfied with dental care. Binomial GEE revealed no statistical significant change in satisfaction with dental care between 1992-2012. In sum, this study has shown that this age group, born in 1942, was stably satisfied with dental care between age 50 and age 70, despite all changes during this time period. Females are more satisfied than men and the most important factors are the experience of attention during the last visit, satisfaction with dental appearance and good chewing capability.

    Reporting dental caries disease in longitudinal studies - a suggestion2016In: Swedish Dental Journal, ISSN 0347-9994, Vol. 40, no 2, 173-179 p.Article in journal (Refereed)
    Abstract [en]

    In general, most infectious and/or lifestyle-related diseases are defined as being present when sufficient signs or symptoms occurs in an individual. The term "sufficient" is a relative concept and a disease can therefore be measured with different degrees of certainty. These symptoms are commonly defined in such a way that it is possible to determine the incidence and prevalence of the disease and also the proportion of individuals that are cured from the disease. If dental caries is an individual disease which can be compared to other diseases regarding incidence and prevalence, it is important to determine for how long an individual must be free from new signs of the disease before being considered cured or free from the disease and to define the "sufficient" signs or symptoms needed for a diagnose. Based on these thoughts, the purpose of this study was to calculate caries incidence and prevalence in a group of adolescents from a definition of dental caries based on ICD-10. This study included all 12 year olds in 1990 who attended a clinical dental examination in 1990-1995 in Orebro County, Orebro, Sweden, yearly during these six years. Dental caries disease at the individual level was defined as Ko2.1 (dentinal caries) according to ICD-bo while freedom of caries was defined as the absence of Ko2.1 during a three-year period. In this study the yearly prevalence was 12%, the three year cumulative incidence was 18% and the incidence rate 13%. Results of this study highlight the poor outcomes in curing caries disease in this age-group, according to the criteria in this study, as only 17% of the children with caries at the outset of the study were free from the disease three years later. Defining both a practical level to measure signs of dental caries, and the period an individual must be free from them to be classified as cured from the disease create new opportunities to compare and communicate the disease of dental caries with other diseases. This way of registration is also of advantage for planning purposes as there the centre of interest must be the individual patient and not the tooth or surface.

    Inequality in oral health related to early and later life social conditions: a study of elderly in Norway and Sweden2015In: BMC Oral Health, ISSN 1472-6831, E-ISSN 1472-6831, Vol. 15, no 20Article in journal (Refereed)
    Abstract [en]

    Background: A life course perspective recognizes influences of socially patterned exposures on oral health across the life span. This study assessed the influence of early and later life social conditions on tooth loss and oral impacts on daily performances (OIDP) of people aged 65 and 70 years. Whether social inequalities in oral health changed after the usual age of retirement was also examined. In accordance with "the latent effect life course model", it was hypothesized that adverse early-life social conditions increase the risk of subsequent tooth loss and impaired OIDP, independent of later-life social conditions. Methods: Data were obtained from two cohorts studies conducted in Sweden and Norway. The 2007 and 2012 waves of the surveys were used for the present study. Early-life social conditions were measured in terms of gender, education and country of birth, and later-life social conditions were assessed by working status, marital status and size of social network. Logistic regression and Generalized Estimating Equations (GEE) were used to analyse the data. Inverse probability weighting (IPW) was used to adjust estimates for missing responses and loss to follow-up. Results: Early-life social conditions contributed to tooth loss and OIDP in each survey year and both countries independent of later-life social conditions. Lower education correlated positively with tooth loss, but did not influence OIDP. Foreign country of birth correlated positively with oral impacts in Sweden only. Later-life social conditions were the strongest predictors of tooth loss and OIDP across survey years and countries. GEE revealed significant interactions between social network and survey year, and between marital status and survey year on tooth loss. Conclusion: The results confirmed the latent effect life course model in that early and later life social conditions had independent effects on tooth loss and OIDP among the elderly in Norway and Sweden. Between age 65 and 70, inequalities tooth loss related to marital status declined, and inequalities related to social network increased.

    Social predictors of less frequent dental attendance over time among older people: population-averaged and person-specific estimates2016In: Community Dentistry and Oral Epidemiology, ISSN 0301-5661, E-ISSN 1600-0528, Vol. 44, no 3, 263-273 p.Article in journal (Refereed)
    Abstract [en]

    ObjectivesLongitudinal studies considering social disparities in the utilization of dental services are scarce. Repeated measures should be accounted for by the use of appropriate statistical methods. The purpose of this study was first to describe the patterns of less frequent dental attendance (less than once a year) over time from the age of 65-70 in Norwegian and Swedish 1942 cohorts. Second, this study estimated the influence of predisposing, enabling and need-related social predictors using marginal model with robust variance estimators and random intercept model, RIM, to account for the clustered structure of the repeated observations. Third, the study aimed to compare the estimates of associations between social predictors and less frequent dental attendance derived from marginal and random intercept models. MethodsIn 2007 and 2012, all residents born in 1942 in selected counties of Norway and Sweden were invited to participate in a questionnaire survey. In Norway, the response rate was 58.0% (n = 4211) in 2007 and 54.5% (n = 3733) in 2012 with a follow-up rate of 70%. The corresponding figures in Sweden were 73.1% (n = 6078) and 72.2% (n = 5697), with a follow-up rate of 80%. Marginal and random intercept models were fitted for population-averaged and person-specific estimates. Design effects were calculated by comparing the results from ordinary logistic regression analyses and the marginal model with robust variance estimators. The proportion of the total variation due to differences between persons was reported using the intraclass correlation coefficient (ICC). ResultsLess frequent dental attendance declined from 14.5% to 12.2% in Norway and from 13.6% to 12.9% in Sweden. According to marginal and random intercept models, time-invariant (gender, country of birth, education) and time-variant social predictors (working status, social network, marital status, smoking and perceived health) contributed to less frequent dental attendance. A likelihood ratio test confirmed that adjustment for clustered observations was appropriate. The ICC was 0.90 in Norway and 0.85 in Sweden. ConclusionsThe prevalence of less frequent dental attendance was low and dropped by increasing age from 65 to 70 years. Both at population and at person-specific levels, being advantaged on social aspects protects against less frequent dental attendance after 65 years of age in the Norwegian and Swedish cohorts investigated.

    Dental status and self-assessed chewing ability in 70-and 80-year-old subjects in Sweden2015In: Journal of Oral Rehabilitation, ISSN 0305-182X, E-ISSN 1365-2842, Vol. 42, no 9, 693-700 p.Article in journal (Refereed)
    Abstract [en]

    The objective was to compare two cohorts of elderly people, 70 and 80 years old, with respect to dental status and self-assessed chewing ability. The hypotheses were as follows: (i) dental status is associated with self-assessed chewing ability; (ii) chewing ability is poorer among the 80-than the 70-year-old subjects. Identical questionnaires were in 2012 sent to all subjects born in 1942 and 1932, living in two Swedish counties. The response rate was 70.1% resulting in samples of 5697 70- and 2922 80-year-old subjects. Answers to questions on self-assessed chewing ability, dental status and some other factors have been analysed. Dental status varied but was in general good; 72% of the 70- and 60% of the 80-year-old subjects reported that they had all or only few missing teeth. Rate of edentulism was 3% and 7%, respectively. Removable partial dentures were reported by 6% and 10%, respectively, implant treatment by 13% in both cohorts. Self-assessed chewing ability was mostly good and correlated with the number of teeth (Spearman rho = 0.46). A majority of the edentulous subjects assessed their chewing ability as very or fairly good. Logistic regression showed that self-assessed chewing ability was significantly associated with a number of dental variables but also with general health. In conclusion, dental status was relatively good at both ages but somewhat poorer in the older cohort. Dental status, some other dental variables and being healthy were in both age groups significantly associated with self-assessed chewing ability.

    Life-course social influences on tooth loss and oral attitudes among older people: evidence from a prospective cohort study2015In: European Journal of Oral Sciences, ISSN 0909-8836, E-ISSN 1600-0722, Vol. 123, no 1, 30-38 p.Article in journal (Refereed)
    Abstract [en]

    This study examined the relationship of trajectories in social condition with oral attitudes and major tooth loss, using the social mobility and accumulation life-course models in a cohort. Whether social-condition inequalities remained stable or changed from 65yr of age to 70yr of age was investigated. In 1992, 6,346 inhabitants born in 1942 and residing in two Swedish counties agreed to participate in a prospective survey. Of the participants in 1992, 3,585 (47.6% men) completed questionnaires in 1997, 2002, 2007, and 2012. In line with the social-mobility model, the prevalence of negative oral attitudes and major tooth loss in participants at 65 and 70yr of age showed a consistent gradient according to social-condition trajectory, whereby it was lowest among those who were persistently high and highest among those who were persistently low, with the upwardly and downwardly mobile categories being intermediate. A linear graded association between the number of periods with disadvantaged social condition and oral health supported the accumulation model. Both the social mobility and accumulation life-course models were supported. Social-condition differentials in negative oral attitudes and tooth loss seem to remain stable or to narrow weakly after the usual age of retirement.
