Objectives The aim of the present survey was to study the association between dental caries and body mass index ( BMI) in Swedish preschool children (born in 1999 ). Methods A population-based and cross-sectional study design was used comprising all 920 5-year-old children in a defined area in and around the city of Lund. Anthropometric measures for the calculation of BMI were retrieved for each child from recordings at Child Health Care Centers ( CHC). The occurrence of caries and fillings in the primary dentition, defined as deft (decayed, extracted, or filled primary teeth) and dt (decayed primary teeth), was collected from the children's dental records. Results The mean BMI was 16.1 (no differences between boys and girls). About 19.2% were overweight, of which 5.1% were obese. Overweight or obese children did not have higher deft or dt than others. However, children with low BMI (below −1 SD of national mean values for Swedish 5-year-olds) had statistically significantly higher deft and dt than children with normal BMI. Conclusions Children with low BMI may be at risk of caries development. Low BMI may be associated with eating habits endangering dental health. [ABSTRACT FROM AUTHOR]

Impact of clinical status and salivary conditions on xerostomia and oral health-related quality of life of adolescents with type 1 diabetes mellitus. Community Dent Oral Epidemiol 2012; 40: 62-69. © 2011 John Wiley & Sons A/S Abstract - Objectives: To investigate the influence of clinical status and salivary conditions on the presence of xerostomia on adolescents with and without type 1 diabetes mellitus (DM1), and further to investigate the influence of clinical status, salivary conditions and xerostomia on oral health-related quality of life (OHQoL) of those with DM1. Methods: A cross-sectional study was performed on 102 adolescents, 51 with DM1 and 51 nondiabetics. Xerostomia was detected by asking a question about the sensation of having 'dry mouth', and Oral Health Impact Profile-14 was used to measure the impact of xerostomia on OHQoL. The clinical status was assessed by using decayed, missing or filled and Community Periodontal indices, and by evaluating oral manifestations; and the following salivary conditions were evaluated: stimulated salivary flow, pH, buffer capacity, total protein, amylase, urea, calcium, and glucose salivary concentrations. Multiple logistic regression analysis was used to evaluate the influence of clinical status and salivary conditions on xerostomia and the impact of xerostomia on the OHQoL of adolescents with DM1. Results: Clinical status and salivary conditions was shown to have no influence on the presence of xerostomia. Bivariate ( P = 0.00) and logistic regression ( P = 0.01) analysis showed a significant association between DM1 and xerostomia. Logistic regression analysis showed association between xerostomia ( P = 0.00) and OHQoL, and caries experience ( P = 0.03) and OHQoL. Conclusions: DM1 showed to be predictive of a high prevalence of xerostomia in adolescents. Caries experience and xerostomia showed to have a negative impact on the OHQoL of adolescents with DM1.

Community Dent Oral Epidemiol 2011; 39: 542-553. © 2011 John Wiley & Sons A/S Abstract - Objective: To investigate the relationship between sense of coherence (SOC), oral health-related behaviour, knowledge of and attitudes towards oral health in an adult Swedish population. Methods: A cross-sectional design with a stratified random sample of 910 individuals aged 20, 30, 40, 50, 60, 70 and 80 years were invited to the study, from Jönköping, Sweden. The investigation used the Swedish short version of the SOC questionnaire comprising 13 items and self-reported questions about oral health habits and knowledge of and attitudes towards oral health. In addition, a self-report questionnaire to elicit demographic information was included. Results: A total of 525 individuals, 261 men and 264 women, answered all the 13-item SOC questions, which constituted the final number of the participants. After adjustment for all the sociodemographic factors included in the analysis, individuals with a stronger SOC had twice as high a chance of having healthier behaviour, including a lower frequency of snacks and drinks between meals, as well as a more positive attitude, such as the importance of having one's own teeth as one gets older, satisfaction with their own teeth, perceiving their teeth as good and no feeling of dental fear, compared with individuals with a poorer SOC. Moreover, SOC and a good knowledge of caries were significantly associated after adjustment for age and gender. Conclusions: SOC was significantly associated with several oral health-related behaviours, attitudes towards oral health and knowledge of dental caries. When working with oral health promotion, SOC could be a way for promoting a better understanding of the behaviour and attitudes of individuals and for enabling dental personals to use that knowledge for the guidance of the individual.

The association between neighborhood social capital and self-reported dentate status in elderly Japanese - The Ohsaki Cohort 2006 Study. Community Dent Oral Epidemiol 2011; 39: 239-249. © 2010 John Wiley & Sons A/S Little is known about the influence of social capital on dental health. The aim of the present cross-sectional study was to determine the association between neighborhood social capital, individual social networks and social support and the number of remaining teeth in elderly Japanese. In December 2006, self-administered questionnaires were sent to 31 237 eligible community-dwelling individuals (response rate: 73.9%). Included in the analysis were 21 736 participants. Five neighborhood social capital variables were calculated from individual civic networks, sports and hobby networks, volunteer networks, friendship networks and social support variables. We used multilevel logistic regression models to estimate the odds ratio (OR) of having 20 or more teeth according to neighborhood social capital variables with adjustment for sex, age, individual social networks and social support, educational attainment, neighborhood educational level, dental health behavior, smoking status, history of diabetes and self-rated health. The average age of the participants was 74.9 (standard deviation; 6.6) years, and 28.5% of them had 20 or more teeth. In the univariate multilevel model, there were statistically significant associations between neighborhood sports and hobby networks, friendship networks and self-reported dentate status. In the multivariable multilevel model, compared with participants living in lowest friendship network neighborhoods, those living in highest friendship network neighborhoods had an OR 1.17 (95% confidence interval, 1.04-1.30) times higher for having 20 or more teeth. There is a significant association between one network aspect of neighborhood social capital and individual dentate status regardless of individual social networks and social support.

Community Dent Oral Epidemiol 2011; 39: 221-229. © 2010 John Wiley & Sons A/S This study aimed to assess socio-economic inequalities in self-reported oral symptoms in Korean adolescents and to assess the association of health behaviours, psychosocial factors and material factors on social gradients in oral symptoms. Cross-sectional data were from the national 2007 Korean Youth Risk Behavior Web-based Survey (KYRBWS). Self-reported oral symptoms included toothache, bad breath, and fractured teeth. Self-assessed socio-economic status (SES) was selected as a measure of SES. To assess socio-economic inequalities in oral symptoms, we used logistic regression models for toothache, bad breath and fractured teeth, and ordinal logistic regression models for the aggregate variable on oral symptoms. We used models adjusting for socio-demographic factors (Model 1) and compared them to models additionally adjusting for health behaviours (Model 2), psychosocial factors (Model 3) and material factors (Model 4). A total of 78 834 students were invited to participate, and the response rate was 94.8% ( n = 74 698). We found that lower self-assessed SES was significantly associated with higher prevalence of each of the three self-reported oral symptoms. Social gradient in the prevalence of each oral symptoms persisted when adjusted for behavioural, psychosocial and material factors. The odds ratio (OR) for the aggregate variable on oral symptoms in the lower SES group was 2.25 (95% CI 2.04, 2.49), and the respective figures after adjusting for behavioural, psychosocial and material factors were 2.17 (95% CI 1.96, 2.39), 1.90 (95% CI 1.73, 2.10) and 2.26 (95% CI 2.04, 2.50). While adjusting for psychosocial factors decreased the OR in the aggregate variable on oral symptoms for lower SES groups, adjusting for health behaviours and material factors hardly changed the OR. There were clear social gradients in three self-reported oral symptoms (toothache, bad breath and fractured teeth) in Korean adolescents. Psychosocial factors explained part of the social inequalities in oral symptoms. Future longitudinal research is required to better address the pathways that explain socio-economic inequalities in oral symptoms during adolescence. [ABSTRACT FROM AUTHOR]

Liu Z, McGrath C, Hägg U. Associations between orthodontic treatment need and oral health-related quality of life among young adults: does it depend on how you assess them? Community Dent Oral Epidemiol 2011; 39: 137-144. © 2011 John Wiley & Sons A/S To determine the association between orthodontic treatment need (OTN) and oral health-related quality of life (OHRQoL). A cross-sectional study involving 273 young adults seeking orthodontic care. OHRQoL was assessed by the short-form Oral Health Impact Profile (OHIP-14) and United Kingdom oral health-related quality of life measure (OHQoL-UK). Study casts were assessed for OTN by: Dental Aesthetic Index (DAI), Index of Orthodontic Treatment Need (IOTN)-Aesthetic Component (IOTN-AC) and Dental Health Component (IOTN-DHC) and Index of Complexity, Outcome and Need (ICON). Variations in OHIP-14 and OHQoL-UK were determined with respect to OTN, and the magnitude of differences was calculated (effect size: ES). There were significant but weak correlations between occlusal indices scores and OHIP-14 scores ( P < 0.05, r < 0.3) and between occlusal indices scores and OHQoL-UK scores ( P < 0.05, r < 0.4). The magnitude of the statistical difference in OHQoL-UK scores was moderate to large with respect to OTN (ES: 0.36-0.87) and largest when DHC (ES = 0.87) and ICON (ES = 0.74) were used. The magnitude of the statistical difference in OHIP-14 scores was relatively lower (ES: 0.21-0.69), but also greatest when DHC and ICON were used to determine OTN (ES 0.69 and 0.50, respectively). Orthodontic treatment need was associated with OHRQoL. The magnitude of the statistical difference between those with and without an orthodontic treatment need was larger when OHRQoL was assessed using OHQoL-UK compared to OHIP-14. DHC and ICON were more useful indices in identifying greater differences in OHRQoL with respect to orthodontic treatment need. [ABSTRACT FROM AUTHOR]

Community Dent Oral Epidemiol 2011; 39: 105-114. © 2010 John Wiley & Sons A/S The presence of oral diseases and disorders can produce an impact on the quality of life of preschool children and their parents, affecting their oral health and well-being. However, socioeconomic factors could confound this association, but it has not been yet tested at this age. To assess the impact of early childhood caries (ECC), traumatic dental injuries (TDI) and malocclusions on the oral health-related quality of life (OHRQoL) of children between 2 and 5 years of age adjusted by socioeconomic factors. Parents of 260 children answered the Early Childhood Oral Health Impact Scale (ECOHIS) (six domains) on their perception of the children's OHRQoL and socioeconomic conditions. Two calibrated dentists (κ > 0.8) examined the severity of ECC according to dmft index, and children were categorized into: 0 = caries free; 1-5 = low severity; ≥6 = high severity. TDI and malocclusions were examined according to Andreasen & Andreasen (1994) classification and for the presence or absence of three anterior malocclusion traits (AMT), respectively. OHRQoL was measured through ECOHIS domain and total scores, and poisson regression was used to associate the different factors with the outcome. In each domain and overall ECOHIS scores, the severity of ECC showed a negative impact on OHRQoL ( P < 0.001). TDI and AMT did not show a negative impact on OHRQoL nor in each domain ( P > 0.05). The increase in the child's age, higher household crowding, lower family income and mother working out of home were significantly associated with OHRQoL ( P < 0.05). The multivariate adjusted model showed that the high severity of ECC (RR = 3.81; 95% CI = 2.66, 5.46; P < 0.001) was associated with greater negative impact on OHRQoL, while high family income was a protective factor for OHRQoL (RR = 0.93; 95% CI = 0.87, 0.99; P < 0.001). The severity of ECC and a lower family income had a negative impact on the OHRQoL of preschool children and their parents. [ABSTRACT FROM AUTHOR]

Ferracane J, Hilton T, Korpak A, Gillette J, Speed McIntyre P, Berg J, Northwest PRECEDENT. Use of caries prevention services in the Northwest PRECEDENT dental network. Community Dent Oral Epidemiol 2011; 39: 69-78. © 2010 John Wiley & Sons A/S This cross-sectional study assessed the use of caries preventive services by Northwest PRECEDENT dental network practitioners and compared the caries experience of patients who received such services in the past 12 months with those who had not. An oral health survey was conducted on approximately 20 patients seen by each of 97 private practice dental practitioners in the network. Eligible patients (total of 1877 aged 3-92) were randomly assessed for the occurrence of one or more new caries lesions as well as having received the following preventive services within the past 12 months: fluoride varnish or gel, sealant in molar or premolar, and prophylaxis. Patients were stratified by gender and age (1-17 years old, 18-64 years old, and 65+ years old). Logistic regression was used to investigate the association between the practitioner characteristics and the use of preventive services, as well as the preventive services and the presence of a new caries lesion in the past 12 months. The percent of patients in age category 1-17 years old/18-64 years old/65+ years old receiving each preventive treatment varied as follows: 95%/85%/81% for prophylaxis, 87%/24%/22% for fluoride, and 27%/2%/0% for sealant. There was a very limited association between the use of a specific preventive service and practitioner gender, and no significant association between use of services and practice location (rural, urban or suburban). There was a significant association between greater use of sealants for dentists with 0-15 years of practice experience as compared with those having more than 25 years of experience. For the 1-17 -year-old age group, boys had about 1.7 times the odds of having a new lesion than girls in the past 12 months, and patients receiving a sealant had 1.9 times the odds of having a new caries lesion. In the 18-64 -year-old group, receiving a prophylaxis in the past 12 months was significantly associated with lower odds for having a new lesion (odds ratio = 0.57). This study reports that aside from prophylaxis, which more than 85% of the patients had received, about one-third of the patients overall received preventive services consisting of either sealants or some type of fluoride treatment in private dental practices in the Northwest PRECEDENT network.
