Article: Aetiology of severe demarcated enamel opacities--an evaluation based on prospective medical and social data from 17,000 children.
[show abstract] [hide abstract]
ABSTRACT: During the 1970s dentists reported an increasing prevalence of a "new" type of enamel disturbance.The disturbance was very specific, with areas of demarcated hypomineralised enamel, and was mostly found in permanent first molars and incisors. Several studies have tried to reveal the aetiology behind the enamel disturbance but sofar no clear factors correlated have been found. The aim of the present study was to evaluate aetiological factors to severe demarcated opacities (SDO) in first permanent molars in a large cohort of children enrolled in the "All Babies in Southeast Sweden" (ABIS) project. ABIS is a prospective study of all children in five Swedish counties born between Oct 1, 1997 and Oct 1, 1999, in all about 17,000 children.They have been followed from birth with recording of a large number of factors on nutrition, diseases, medication, infections, social situation etc. With help from 89 Public Dental Service clinics in the same area preliminary examinations of the children, born between Oct 1,1997 and Oct 1,1999, reported 595 children with severe demarcated opacities (SDO) in first molars.These children and a randomly selected age matched group of 1,200 children were further invited to be examined by specialists in paediatric dentistry. At these examinations 224 severe cases were identified as well as 253 children completely without enamel disturbances among children registered in ABIS.These two groups were analysed according to any correlation between SDO and variables in the ABIS databank. The analyses showed no association between SDO and pre-, peri-, and neonatal data. However, we found a positive association between SDO and breastfeeding for more than 6 months (OR 1.9; 95% CI 1.1-3.2), late introduction of gruel (OR 1.9; 95% CI 1.1-2.9), and late introduction of infant formula (OR 1.8; 95% CI 1.2-2.9). A combination of these three variables increased the risk to develop SDO by more than five times (OR 5.1; 95% CI 1.6-15.7). No significant associations were found to other environmental, developmental, or medical factors. We conclude that nutritional conditions during first 6 months of life may influence the risk to develop severe demarcated opacities in first permanent molars.Swedish dental journal 01/2011; 35(2):57-67. · 0.45 Impact Factor -
Article: Oral health in young adults with long-term, controlled asthma.
[show abstract] [hide abstract]
ABSTRACT: To study oral health in young adults with long-term, controlled asthma. 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. 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. 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.Acta odontologica Scandinavica 01/2011; 69(3):158-64. · 1.41 Impact Factor -
Article: BMI status in Swedish children and young adults in relation to caries prevalence.
[show abstract] [hide abstract]
ABSTRACT: 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.Swedish dental journal 01/2011; 35(1):1-8. · 0.45 Impact Factor -
Article: Oral health in pre-school children with asthma--followed from 3 to 6 years.
[show abstract] [hide abstract]
ABSTRACT: The aim of this study was to investigate caries and its determinants in preschool children with and without asthma, followed from 3 to 6 years. Caries, plaque, and gingivitis were examined at 3 and 6 years of age in 64 asthmatic children and 50 matched, healthy control children. Furthermore, at 6 years radiographic examination and saliva sampling were conducted. The parents were interviewed about various oral health-related factors. Initial caries increment between 3 and 6 years of age was statistically significant higher for children with asthma compared with children without asthma (P < 0.05). Asthmatic children had more bleeding gingivitis and a higher consumption of sugary drinks than healthy children at 3 years of age (P < 0.05). At both 3 and 6 years of age, the asthmatic children were more frequently mouth breathers than healthy children, only statistically significant for 6-year olds (P < 0.05). Preschool children with asthma at 3 years of age run a higher risk of developing caries lesions until 6 years of age compared with children without asthma. Children with asthma have a higher prevalence of bleeding gingivitis, a higher intake of sugary drinks and are more frequently mouth breathers than preschool children without asthma.International Journal of Paediatric Dentistry 05/2010; 20(3):165-72. · 1.01 Impact Factor -
Article: Assessment of traumatic injuries to primary teeth in general practise and specialized paediatric dentistry.
[show abstract] [hide abstract]
ABSTRACT: The aim of this prospective study was to compare diagnosis, severity of trauma and treatment of traumatic injuries to the primary dentition in two groups of children, the first recommended for treatment by general practitioners and the second referred for treatment by a specialist paediatric dentist. A total of 323 children with traumatic injuries, 184 boys and 139 girls aged 7-83 months, participated in the study. All the children had first presented at a Public Dental Service clinic where they were examined by general dentists who decided, based on the severity of the trauma, to assign each child to one of the following two groups: Group A--recommended for treatment at the general practise (166 children with 257 traumatized incisor teeth). Group B--recommended for referral to a specialist in paediatric dentistry (157 children with 261 traumatized incisor teeth). Even in Group A, the specialist controlled the treatment decisions. The clinical diagnose and follow-up followed the recommendations presented by Andreasen & Andreasen. The distribution of trauma by age was similar in both groups, with about 60% occurring between 1 and 3 years. More injured teeth were extracted in children in Group B (n = 111) than in Group A (n = 33). A higher percentage of intruded primary incisors were recorded in Group B (24%) compared with Group A (16%). Similarly, the percentage of concussions/subluxations, lateral luxations and complicated crown fractures was higher in Group B than in Group A. The group referred for specialist treatment had more severe injuries and needed more complicated treatment than the group recommended for care by general dentists. However, the rate of sequelae in permanent successors was the same in both.Dental Traumatology 02/2010; 26(2):129-32. · 1.20 Impact Factor -
Article: Oral health in preschool children with asthma.
[show abstract] [hide abstract]
ABSTRACT: The aim of this study was to investigate oral health and its determinants in 3-year-old and 6-year-old children with asthma. Caries and gingivitis were examined in 127 asthmatic (all children with asthma in a selected area and born during a specific time period) and 117 matched, healthy control children. The parents were interviewed regarding various oral-health-related factors. The mean dfs (+/- standard deviation) in the 3-year-old with asthma was 1.4 +/- 3.2 compared with 0.5 +/- 1.2 in the controls (P < 0.05). The corresponding figures for the 6-year-old were 2.5 +/- 3.9 and 1.8 +/- 2.8. The 3-year-old asthmatic children had more gingival bleeding than the healthy controls (P < 0.05). There were no significant differences in gingivitis in the 6-year-old children. Asthmatic children reported higher consumption of sugar-containing drinks and were more frequently mouthbreathers than healthy children (P < 0.05). In 3-year-old children with asthma and immigrant background, the mean dfs was higher compared with immigrant children in the control group (P < 0.01). The results indicate that preschool children with asthma have higher caries prevalence than healthy children. The factors discriminating for caries in asthmatic children are higher intake of sugary drinks, mouth breathing, and immigrant background.International Journal of Paediatric Dentistry 07/2008; 18(4):243-50. · 1.01 Impact Factor -
Article: Body adiposity status in teenagers and snacking habits in early childhood in relation to approximal caries at 15 years of age.
[show abstract] [hide abstract]
ABSTRACT: 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. 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. 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. 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. 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.International Journal of Paediatric Dentistry 06/2008; 18(3):189-96. · 1.01 Impact Factor -
Article: Thirty year trends in the prevalence and distribution of dental caries in Swedish adults (1973-2003).
[show abstract] [hide abstract]
ABSTRACT: The aim of the present investigation is to report on the trends in the prevalence and severity of dental caries and dental status in an adult Swedish population over a 30-year period (1973-2003). Four cross-sectional epidemiological studies in 1973, 1983, 1993, and 2003 were performed in Jönköping, Sweden.A random sample of individuals aged 20, 30, 40, 50, 60, 70, and 80 years were examined clinically and radiographically, a total of 2521 individals. Diagnostic variables were edentulousness, number of teeth, initial and manifest caries lesions, restorations, fissure sealants, and quality of restorations (secondary caries and overhangs). The percentage of edentulous 40- to 70-year-old individuals decreased during the 30-year period from 16% to 1%. The distribution of individuals by DFS in the age groups 20-50 years showed a gradual shift towards a positively skewed distribution between the years 1973 to 2003. There was a steady decrease in mean number of DFS in the age groups 20-50 years. In the 20-year-olds the mean number of DFS decreased by 72% and for 50-year-olds, by 37%. In conclusion there has been a marked decrease in DFS in adults up to middle age and a marked reduction in edentulousness over a thirty year period. This shows that the decrease in caries levels in children and adolescents is also occurring among adults.Swedish dental journal 02/2008; 32(2):57-67. · 0.45 Impact Factor -
Article: Caries prevalence and distribution in individuals aged 3-20 years in Jönköping, Sweden, over a 30-year period (1973-2003).
[show abstract] [hide abstract]
ABSTRACT: Oral health status of individuals aged 3-80 years in the city of Jönköping, Sweden, has been assessed in a series of epidemiological studies over a 30-year period. To analyse the changes in caries prevalence and caries distribution in child population sample groups, based on studies performed in 1973, 1978, 1983, 1993, and 2003. Each time point included 500 randomly sampled individuals, divided into age groups of 3, 5, 10, 15, and 20 years. Results. Thirty-five per cent of 3-year-olds were caries free in 1973, compared with 69% 30 years later. Decayed and filled primary (dfs) and permanent surfaces (DFS) were reduced by 50-80% between 1973 and 2003. Adolescents aged 10 and 15 years exhibited the most pronounced reduction in DFS on the occlusal surfaces. By 2003, 90% of the proximal carious lesions in 15-year-olds were initial carious lesions. In 2003, about 60% of 15-year-olds had a DFS of < or = 5, while about 7% exhibited a DFS of > or = 26. Despite the dramatic decline in the prevalence of caries, caries remains a health problem among children, particularly those of preschool age. Continuous epidemiological studies are recommended to evaluate preventive measures.International Journal of Paediatric Dentistry 01/2008; 18(1):18-26. · 1.01 Impact Factor -
Article: Location, complications and treatment of mesiodentes--a retrospective study in children.
[show abstract] [hide abstract]
ABSTRACT: Out of approximately 11 500 children, who had been referred to the Department of Paediatric Dentistry at the Institute for Postgraduate Education,Jönköping, Sweden, 97 individuals had a total of 123 mesiodentes. Their dental records and radiographs were analysed in order to study the clinical and radiographic features of the mesiodentes, to record the complications caused by them and to evaluate different forms of treatment. In the present study, the predominant location of the mesiodentes was palatally with 39 per cent in an inverted position. Arrest of the permanent incisors eruption, midline diastema and displacement or rotation of the incisors, were the most common complications found. On the contrary, no follicular cysts or resorption of either the mesiodens or the adjacent teeth were found. Fourty-three out of the 97 individuals were radiographically followed and no pathological findings were recorded. This study shows that the risk of complications caused by the mesiodentes seems to be very low and therefore a more restrictive attitude towards their surgical removal can be recommended.Swedish dental journal 02/2005; 29(1):1-9. · 0.45 Impact Factor -
Article: Oral health of individuals aged 3-80 years in Jönköping, Sweden during 30 years (1973-2003). I. Review of findings on dental care habits and knowledge of oral health.
[show abstract] [hide abstract]
ABSTRACT: The aim of the present study was to compare data on dental care habits and knowledge of oral health in four cross-sectional epidemiological studies carried out in 1973,1983,1993, and 2003. The 1973 study constituted a random sample of 1,000 individuals evenly distributed in the age groups 3, 5, 10, 15, 20, 30, 40, 50, 60, and 70 years. The same age groups with addition of a group of 80-year-olds were included in the 1983, 1993 and 2003 studies, which comprised 1,104, 1,078, and 987 individuals, respectively. A questionnaire about dental care habits and knowledge of oral health was used in connection with a clinical and radiographic examination. The same questions were used in all the four studies. An addition to the 1993 and 2003 investigations were questions concerning ethnic background. In 2003 approximately 90-95 per cent of all individuals were visiting the dentist on a regular basis every or every second year. The 30- and 40-yea r-olds, however, did not visit a dentist as regularly in 2003 as in 1993. In these age groups 21-24 per cent of the individuals, respectively, reported that they had not visited a dentist in the last 2 years. Almost all children 3-15 years old received their dental care within the Public Dental Service (PDS). During the period 1973-2003 an increase in percentage of individuals aged 20-50 years treated by the PDS was seen compared to private practice, while among 60-80 year-olds there were only minor changes. Most so-year-olds and older received their dental care by private practitioners. About 70-80 per cent of all adults in 2003 were enrolled in a recall system on the dentist's initiative while in 1973 most appointments were based on the patient's own initiative. The number of individuals who were frightened, 5-17 per cent, or felt discomfort at the prospect of an appointment with the dentist was more or less the same during the whole period. The knowledge of the etiology of dental diseases did not changed much between 1973 and 2003. The frequency of toothbrushing increased since 1973 and in 2003 more than 90 per cent of all individuals brushed their teeth twice or once a day. The use of dental floss and toothpicks decreased in 2003 compared to 1983 and 1993. Almost all individuals in 2003 used fluoride toothpaste. It was obvious that the dental team constituted the main source of dental health information. For the age groups 20 and 30 years information from friends and relatives was also important. In the age groups 3-20 years up to 45 per cent of the individuals were consuming soft drinks every day or several times a week.Swedish dental journal 02/2005; 29(4):125-38. · 0.45 Impact Factor -

[show abstract] [hide abstract]
ABSTRACT: The aim of this epidemiological study was to analyze various clinical and radiographic data on oral health and compare the results to those of three cross-sectional studies carried out in 1973 and 1983, and 1993. In 1973, 1983, 1993, and 2003 a random sample of 1,000; 1,104; 1,078; and 987 individuals, respectively, were studied. The individuals were evenly distributed in the age groups 3, 5, 10, 15, 20, 30, 40, 50, 60, 70, and 80 years. In 1973 80-year-olds were not included. All subjects were inhabitants of the City of Jönköping, Sweden. The clinical and radiographic examination assessed edentulousness, removable dentures, implants, number of teeth, caries, restorations and overhangs, oral hygiene, calculus, periodontal status, endodontic treatment, and periapical status. The number of edentulous individuals in the age groups 40-70 years was reduced from 16 per cent in 1973 to 8 per cent in 1993, and to 1 per cent in 2003. The mean number of teeth increased, and up to the age of 60 years, individuals had more or less complete dentitions. During the 30-year period,the number of carious lesions and restorations decreased in general. In the 15-year-olds the decrease in number of restored tooth surfaces was 900 per cent and the corresponding figure for 30-year-olds was 79 per cent. The age groups 60-800 years showed an increase in number of restored tooth surfaces and had as a mean 50 filled tooth surfaces. The oral health among 3-5-year-olds improved markedly between 1973 and 1993. In 2003, however, there was no further improvement in 3- and 5-year-olds compared to 1993. Generally, restorations in 2003 exhibited a high quality and 90-95 per cent had no proximal overhangs. In 1973 this figure was about 60 per cent. In the age groups 20-50 years there were continuously fewer teeth fitted with crowns or bridges during the 30-year period. In 1973 the 50-year-olds had a mean of 24.5 per cent of the teeth crowned and in 2003 6.8 percent. Compared to data from 1973 there was a reduction by half concerning occurrence of plaque and gingivitis in 2003. The frequency of individuals with one or more periodontal pockets (> or = 4 mm) increased with age. In 2003 the bone level at the age of 60 years corresponded to the bone level at the age of 40 years in 1973. The percentage of endodontically treated teeth was lower in 2003 in all age groups compared to 1973, 1983, and 1993. The percentage of endodontically treated teeth with periapical orjuxtaradicular destructions was generally lower in 2003 than in the earlier surveys, about 20 per cent in 2003 compared to 25-30 per cent in 1973,1983, and 1993. The comparison of the four studies shows that there has been a great overall improvement in oral health over this 30-year period.Swedish dental journal 01/2005; 29(4):139-55. · 0.45 Impact Factor -
Article: Dental treatment of the primary dentition in 7-12 year-old Swedish children in relation to caries experience at 6 years of age.
[show abstract] [hide abstract]
ABSTRACT: In most Swedish counties, epidemiological data on the permanent dentition are collected on patients between 7 and 19 years of age. However, for the primary dentition, epidemiological data are only available for the 3-6-year-old age groups. As far as we know, no studies have investigated the relation between caries prevalence in the early primary dentition and caries prevalence or treatment performed in the late primary dentition. Thus, the purpose of the present study was to investigate the relationship between dental treatment in the primary dentition of Swedish children 7-12 years of age and caries experience in the primary dentition at 6 years of age. This retrospective study is based on record data from a randomly selected sample comprising 10% of all children born in 1987 in Jönköping County (n=433). Of these children, 381 had been treated regularly at the Public Dental Service clinics between 7 and 12 years of age and were included in the study. It was found that children with previous caries experience at 6 years of age received significantly more treatment during the studied period compared to children who were caries free at the same age. The children with caries experience required a mean of 3.5 times more treatments compared to caries-free children. The present study underlines the importance of early detection and prevention of caries in the primary dentition if optimal dental health is to be expected in the late primary dentition.Swedish dental journal 02/2004; 28(2):61-6. · 0.45 Impact Factor -

ABSTRACT: In most Swedish counties, epidemiological data on the permanent dentition are collected on all patients aged 7-19 years. For the primary dentition, epidemiological data are only reported for the 3-6-year-old age groups. The purpose of the present study was to investigate what treatments had been made in the primary dentition during the period when the children were 7 to 12 years old. The sample size constituted 10% of all children born in 1987 and regularly treated at Public Dental Service clinics in Jönköping County between 7 and 12 years of age. Data were extracted from the dental records. The most common treatments--new restorations and replacements of restorations--comprised 72% of all treatment. Replacements of restorations constituted 31% of all restorations performed between 7 and 12 years of age, and a majority (81%) of these had been made when the children were 7-9 years old. The mean defs value at 6 years of age was 1.9. The mean number of treatments performed per child between 7 and 12 years of age was 2.5. The result of the present study indicates that more treatments in the primary dentition are performed after 6 years of age than before.Swedish dental journal 02/2003; 27(2):77-82. · 0.45 Impact Factor -
Article: Caries prevalence and distribution in 20–80‐year‐olds in Jönköping, Sweden, in 1973, 1983, and 1993
[show abstract] [hide abstract]
ABSTRACT: Abstract – In 1973, a cross-sectional study on oral health status was performed on 1000 individuals in the age groups 3–70 years in Jönköping, Sweden. In 1983 and 1993, new cross-sectional studies were carried out in the age groups 3–80 years. The aim of the present study was to analyze caries prevalence and distribution in the three investigations 1973, 1983, and 1993 in the age groups 20–80 years. In the younger age groups (20–40 years), a larger proportion of individuals with good oral health was found in 1993 than in 1973 or 1983. A steady increase in the number of teeth in the age groups 40–80 years could be found, which was also reflected in the increasing number of decayed and filled tooth surfaces (DFS) in the same age groups. A marked decrease in proximal DFS in 20–50-year-olds in 1993 compared to 1973 and 1983 was found. However, a rather large and unchanging group of individuals suffering from severe caries was also observed. This situation demands an individualized caries treatment strategy based on risk assessment.Community Dentistry And Oral Epidemiology 01/2002; 28(2):90 - 96. · 1.89 Impact Factor -
Article: On the retention and effectiveness of fissure sealant in permanent molars after 15–20 years: a cohort study
[show abstract] [hide abstract]
ABSTRACT: Abstract – The aim of the present study was to clinically evaluate fissure sealants on the occlusal fissures and buccal pits of permanent first and second molars after 20 and 15 years, respectively. The population consisted of 72 children, each of whom had had their four first molars sealed between 1977 and 1980. At the annual examinations, all caries-free, newly erupted second molars were sealed. When sealant was applied to the second molars, the first molars were checked and sealant was reapplied to those that had deficient sealants. At the follow-up, when the subjects were 26–27 years of age, 27 in the original group had moved from the community. Thus, the present result is based on 45 subjects. One hundred and fifty-three sealed first molars and 161 sealed second molars were available for inspection. At the follow-up examination of the first molars 20 years after sealant had been applied, 65% showed complete retention, 22% partial retention without caries, and 13% caries or restoration in the occlusal fissures or buccal pits. At the 15-year follow-up of the second molars, the corresponding figures were 65%, 30%, and 5%, respectively. Of the restored or carious molars, significantly more were found in the mandible than in the maxilla (P<0.001). This longitudinal study showed that pit and fissure sealants – applied during childhood – have a long-lasting, caries-preventive effect.Community Dentistry And Oral Epidemiology 07/2001; 29(4):302 - 307. · 1.89 Impact Factor
