Abstract [en]

OBJECTIVES: To test the hypothesis that parental factors in early childhood influence approximal caries experience in young adults.

METHODS: A cohort of 494 individuals was followed longitudinally from 1 to 20 years of age. Data were retrieved from parental interviews and questionnaires when the child was 1 and 3 years of age. At age 20, the participants underwent bitewing radiographic examination. Based on the number of approximal caries lesions (Da), stratified into initial (Di ) or manifest caries (Dm ) and approximal fillings (Fa), the participants were divided into two main groups: those with: (a) 0 Dim Fa (n = 244) and (b) >0 Dim Fa (n = 250). A subgroup was also created (≥8 Dim Fa; n = 33).

RESULTS: Toothbrushing with fluoride toothpaste at 3 years of age less than twice a day (OR 1.6, 95% CI 1.0-2.6) and the participants' mothers' self-estimation of their oral health care as "less than optimal" were important risk factors for developing caries (>0 Dim Fa OR 2.0, 95% CI 1.3-3.1). An interaction effect between toothbrushing at 3 years of age less than twice a day and consumption of caries risk products > 3 times a day further increased the caries experience in young adults (≥8 Dim Fa OR 8.3, 95% CI 1.8-37.8) together with maternal anxiety about dental treatment (OR 7.4 95% CI 1.6-34.6).

CONCLUSIONS: Parental factors in early childhood are associated with caries experience at 20 years of age.

Abstract [en]

The aim of this study was to evaluate the effect on oral health, at age 9 years, of daily oral supplementation with the probiotic Lactobacillus reuteri, strain ATCC 55730, to mothers during the last month of gestation and to children through the first year of life. The study was a single-blind, placebo-controlled, multicenter trial involving 113 children: 60 in the probiotic and 53 in the placebo group. The subjects underwent clinical and radiographic examination of the primary dentition and carious lesions, plaque and gingivitis were recorded. Saliva and plaque were sampled for determination of mutans streptococci (MS) and lactobacilli (LB) in saliva and plaque as well as salivary secretory IgA (SIgA). Forty-nine (82%) children in the probiotic group and 31 (58%) in the placebo group were caries-free (p < 0.01). The prevalence of approximal caries lesions was lower in the probiotic group (0.67 ± 1.61 vs. 1.53 ± 2.64; p < 0.05) and there were fewer sites with gingivitis compared to the placebo group (p < 0.05). There were no significant differences between the groups with respect to frequency of toothbrushing, plaque and dietary habits, but to intake of fluoride supplements (p < 0.05). There were no intergroup differences with respect to L. reuteri, MS, LB or SIgA in saliva. Within the limitation of this study it seems that daily supplementation with L. reuteri from birth and during the first year of life is associated with reduced caries prevalence and gingivitis score in the primary dentition at 9 years of age.

Abstract [en]

Objective. To investigate the prevalence, distribution and severity of dental erosion and its association with lifestyle, oral and general health in young adults. Materials and methods. Four hundred and ninety-four individuals, 20-years of age, participated. Dental erosion in molars and maxillary incisors was evaluated. Caries, plaque and gingivitis were registered. Saliva samples were taken and the subjects were interviewed about behavioural and dietary habits and oral and general health. Body mass index (BMI) was calculated. The individuals were sub-divided into two groups according to the presence and absence of dental erosion: within the group with erosion was a sub-group of individuals with extensive erosion. Results. Of the individuals 25% had no erosion, 75% had erosion and 18% had extensive erosion. Erosion was found in molars in 74% of the individuals and on buccal and palatal surfaces in maxillary incisors in 4% and 7%, respectively. Cupping was seen in 65% of individuals and severe erosion in molars in 1.6%. Compared to subjects with no erosion, those with extensive erosion had a higher consumption of soft drinks (p = 0.05), caries prevalence (p < 0.01), prevalence of mutans Streptococci (p < 0.01) and BMI (p < 0.05). Furthermore, subjects with erosion had higher caries prevalence (p < 0.01) and BMI (p < 0.01) than those with no erosion. Conclusions. Swedish young adults have a high prevalence of dental erosion, but the level of severe erosion is low. The study disclosed a relationship between dental erosion and behavioural factors, oral health and BMI.

Abstract [en]

Background/Aim: There are few studies of caries development and caries-related factors from early age to young adulthood. The aim of the present study is to analyse caries prevalence in 20-year-olds in relation to their previous caries experience. Method: Oral health from 3 to 20 years of age was followed longitudinally in a cohort of 499 individuals. The clinical and radiographic incidence of caries and restorations in 494 20-year-olds was related to caries data at 3, 6 and 15 years of age. Results: Twenty-six per cent of the 20-year-olds were caries-free. The mean number of initial and manifest lesions and restorations (Di + mFS) was 5.8. Initial lesions comprised 40% of the Di + mFS. Of the occlusal surfaces of molars and premolars, 12 and 4%, respectively, had manifest caries or restorations. Compared with individuals who had been caries-free during childhood (primary dentition) and adolescence, those with a history of caries activity while growing up had statistically significantly more approximal lesions at the age of 20 (DmFSa 0.6 vs. DmFSa 4.6, respectively). Those with manifest caries during childhood but caries-free at 15 years had a low caries prevalence at 20 years of age (DmFSa 1.3). Few new lesions developed after age 15. However, 50% of initial lesions at this age had progressed to manifest lesions at age 20. Conclusion: There is a relationship between caries prevalence at age 20 and early caries experience.

Abstract [en]

AIM: To describe the frequency of overweight and obesity from birth to 20 years of age and analyse weight at 20 years of age in relation to weight and weight development during early childhood and adolescence.

METHODS: A longitudinal, population-based study, which followed 496 children from birth to 20 years of age. Information about weight and height was collected from health records at child health centres and school health care. At 20 years of age, weight and height measurements were taken by one of the authors.

RESULTS: At 20 years of age, 124 (25%) of the youth were obese or overweight. Of these youths, 60% had normal weight at 5.5 years. Of the teenagers who were overweight/obese at 15 years, 79% remained overweight/obese at 20 years of age. Out of the 124 overweight/obese at 20, 47% had normal weight at 15 years. [Corrections added after online publication on April 18, 2012: 'Out of the 124 obese at 20' has been changed to 'Out of the 124 overweight/obese at 20']. No relation was found between rapid weight gain during preschool age and overweight and obesity in 20-year-olds.

CONCLUSIONS: The majority of those who were overweight/obese at 20 years of age were recruited after 5.5 years of age, and half of them in their late teens. Thus, during the preschool period, the entire population should be the target of primary prevention from overweight/obesity and, in the case of teenagers, prevention strategies should be developed for the whole population as well as treatment strategies for teenagers with established overweight/obesity.

Abstract [en]

Overweight and obesity are increasing as health problems at global level. Dental caries and obesity are both multifactorial diseases and are associated with dietary habits. The aim of the present study was to investigate the relationship between body weight status and caries prevalence in an unselected population followed from pre-school years to young adulthood. The present investigation was designed as a longitudinal analysis of the association between overweight/obesity and dental caries in one population at 3, 6, 15 and 20 years of age. The result shows that adolescents (15 years) and young adults (20 years) who are overweight/obese had a statistically significantly higher caries prevalence than normal-weight young people. At 6 years of age, the odds (OR) of having caries among obese children are 2.5 times higher than the odds for caries among six-year-old children of normal weight (p = 0.04). At 3 years of age, no association between overweight/obesity and caries was found. To conclude, overweight and obese adolescents and young adults had more caries than normal-weight individuals. The present study emphasises the need for multidisciplinary approaches to change the lifestyle factors causing both overweight/obesity and dental caries.

Abstract [en]

Objective. To study oral health in young adults with long-term, controlled asthma. Material and methods. Twenty 18- to 24-year-olds with a mean duration of asthma of 13.5 [standard deviation (SD) 5.4] years and 20 matched healthy controls were included. A clinical examination was performed and the prevalences of caries, erosions, gingival inflammation, cervicular fluid and periodontal pockets and the plaque formation rate were registered. The salivary flow rate and the numbers of mutans Streptococci and Lactobacilli in saliva were determined. Plaque pH was measured after a sucrose rinse for up to 40 min at two approximal sites. The participants were interviewed regarding dietary and oral hygiene habits. Results. The mean (SD) DFS, including manifest and initial caries, was 8.6 (10.6) in the asthma group and 4.0 (5.2) in the control group (P = 0.09). Initial caries lesions were more common in the asthma group than in the control group: 6.0 (8.1) and 1.3 (2.0), respectively (P = 0.02). The asthma group had more gingivitis (P = 0.01) and a lower stimulated salivary secretion rate than the controls (P = 0.01). The asthmatics also had a somewhat, although not statistically significant, lower initial pH value in plaque and a more pronounced pH drop compared with the controls. In the asthma group, 65% reported frequent mouthbreathing, compared with 10% of the controls (P = 0.01). No differences were found in tooth-brushing or dietary habits between the groups. Conclusion. Young adults with long-term, controlled asthma had more initial caries, more gingival inflammation and a lower stimulated salivary secretion rate than individuals without asthma.

Abstract [en]

The aim of the present case-control study was to investigate dental caries, various caries-related factors as well as gingival condition, in 12- to 16-year-olds with long-term asthma (n = 20) and a matched healthy control group (n = 20). Data on dietary and oral hygiene habits, numbers of mutans streptococci and lactobacilli in saliva were also obtained. The plaque pH drop after a sucrose rinse was measured up to 40 min at 2 approximal tooth sites. A lower salivary flow rate was found in the asthma group compared to the control group (p < 0.05). The mean (± SD) of DFS, including manifest and initial caries, was 4.9 ± 5.5 in the asthma and 1.4 ± 2.3 (p < 0.01) in the control group. Only 1 adolescent in the asthma group was caries free compared to 13 in the control group. Concerning pH in plaque, adolescents with asthma had a lower initial value (p < 0.01) and final pH (p < 0.05) than the control group. The Cariogram data showed that 55% of the subjects in the control group had ‘a high chance of avoiding caries’ compared to 10% in the asthma group (p < 0.01). The asthmatic adolescents had higher numbers of sites with gingival bleeding (p < 0.01). To conclude, adolescents with long-term asthma had a higher total DFS and caries risk (according to Cariogram), decreased salivary rate, more gingival bleeding and lower plaque pH than adolescents without asthma.

Abstract [en]

BACKGROUND: The prevalence of overweight and obesity in children is steadily increasing in many countries. Dental caries and obesity are both multifactorial diseases and are associated with dietary habits.

OBJECTIVE: The purpose of this study was to investigate the relationship between body weight status in adolescents and snacking habits in early childhood to approximal caries prevalence at 15 years of age.

METHODS: This study is part of a series of surveys of oral health in children followed from the ages of 1 year to 15 years. Body adiposity status was estimated at 13.5-16.4 years using the International Obesity Task Force cut-off values [age-specific body mass index (isoBMI)]. Information about snacking habits in early childhood was collected from interviews conducted at 1 year and 3 years. Approximal caries information was obtained from bitewing radiographs at 15 years. Data related to isoBMI and approximal caries were available in 402 teenagers.

RESULT: Adolescents with isoBMI > or = 25 (n = 64) had an approximal caries prevalence that was a mean of 1.6 times higher than those with isoBMI < 25 (n = 338) (4.64 vs. 2.94; P = 0.014). Furthermore, children's snacking habits at an early age were associated with approximal caries at 15 years.

CONCLUSION: Overweight and obese adolescents had more approximal caries than normal-weight individuals. Moreover, the frequent consumption of snacking products during early childhood appears to be a risk indicator for caries at 15 years. Future preventive programmes should therefore include, on a multidisciplinary level, strategies to prevent and reduce both obesity and dental caries at an early age.
