The aim of the present study was to describe awareness and attitudes related to dental erosive wear among 18-yr-old adolescents in Oslo and to explore attitudinal differences between participants with and without the condition. All 18-yr-old subjects scheduled for their routine examination at the Public Dental Service clinics during 2008 (n = 3,206) were invited, and 1,456 agreed to participate (a response rate of 45%). The data were collected using structured questionnaires and by clinical examination of the participants. Dental erosive wear was assessed using a pictorial manual - the Visual Erosion Dental Examination scoring system - as a guide. Overall, 88% of participants had heard about dental erosive wear; however, of participants with erosive lesions only 56% were aware of, and only 47% could recall their dentist mentioning, the condition. Participants with erosive wear were more likely to have low or moderate positive attitudes towards acidic drink consumption and to be reluctant to change. In multivariate analyses controlling for gender and behavioural variables, weak or moderate positive awareness of acidic drinks remained significantly associated with higher erosion risk. This study emphasizes the importance of assessment and understanding of awareness and attitudinal aspects in relation to dental erosive wear.
The aims of this study were to investigate the prevalence of dental erosion among Swedish children and adolescents and to examine its relation to soft drink consumption. It was hypothesized that the prevalence of dental erosion would be higher in boys than girls,that it would show a correlation with soft drink consumption and that a further simplification ofa previously-used partial recording screening system for dental erosion would have an acceptable sensitivity and specificity. 801 individuals were invited to participate, of whom 609 (75%) accepted. 135 were 5-6 years, 227 were 13-14 years, and 247 were18-19 years old. A questionnaire survey of each individual's soft drink consumption habits, in addition to a clinical examination, were performed. Severe erosion extending into dentine on one or more maxillary anterior teeth/ molars was found to be 13.3% in the 5-6 group, 11.9% in 13-14 group and 22.3% in 18-19 group. The total prevalence for all age groups was 16.4%. The severity of erosion was highest among 18-19 year-old boys, 34.4 % of whom exhibited one or more teeth with severe erosive damage while none of the girls did so. Soft drink consumption was significantly correlated with severity of dental erosion in the 18-19 and 13-14 groups but not in the 5-6 years old group. A simplified erosion partial recording system (SEPRS) using 4 (permanent) or 6 (primary) surfaces as markers showed excellent sensitivity (100%/100%, respectively) and specificity (98%/100%, respectively) in relation to scoring of all maxillary canines/incisors and first permanent/all primary molars. In view of the high prevalence of dental erosion and soft drink consumption among Swedish children and adolescents reported here,there is clearly a need for a national epidemiological registration system as well as for community-based preventive programs to be implemented. The hypothesis that dental erosion would be higher in boys than girls and that it would show a correlation with soft drink intake was confirmed.
High consumption of fruit juices and carbonated drinks has been related to dental erosion. Teenage male Icelanders consume about 800 ml of carbonated drinks per day on average and this corresponds with the main age group and gender of patients seen with erosion. This study examined the prevalence of dental erosion in 15-year-old children in Reykjavík and looked at the association between erosion and some lifestyle factors in a case-control study drawn from the same sample. A 20% sample of the 15-year-cohort population (n = 278) was selected. Dental erosion was classified by location and severity (1 = enamel erosion; 2 = dentine erosion; 3 = severe dentine erosion) and was seen in 21.6% of subjects (68.3% male; 72% scored as grade 1; 23% grade 2; 5% grade 3). Control subjects were the first healthy subjects examined after a case subject had beens diagnosed. In the case-control study, information was gathered by multiple-choice questionnaire on symptoms of gastric reflux, tooth sensitivity, some lifestyle and dietar-factors. Several lifestyle and dietary factors, previously shown to be significantly related to dental caries in Icelandic teenagers, showed no significant relationship to tooth erosion. Although dietary factors are probably important in causing erosion, dietary recall questionnaires did not help in discovering individuals likely to develop erosion.
Little attention has been directed towards identifying the relationship between physical exercise, dental erosive wear and salivary secretion. The study aimed i) to describe the prevalence and severity of dental erosive wear among a group of physically active young adults, ii) to describe the patterns of dietary consumption and lifestyle among these individuals and iii) to study possible effect of exercise on salivary flow rate.
Young members (age range 18-32 years) of a fitness-centre were invited to participate in the study. Inclusion criteria were healthy young adults training hard at least twice a week. A non-exercising comparison group was selected from an ongoing study among 18-year-olds. Two hundred and twenty participants accepted an intraoral examination and completed a questionnaire. Seventy of the exercising participants provided saliva samples. The examination was performed at the fitness-centre or at a dental clinic (comparison group), using tested erosive wear system (VEDE). Saliva sampling (unstimulated and stimulated) was performed before and after exercise. Occlusal surfaces of the first molars in both jaws and the labial and palatal surfaces of the upper incisors and canines were selected as index teeth.
Dental erosive wear was registered in 64% of the exercising participants, more often in the older age group, and in 20% of the comparison group. Enamel lesions were most observed in the upper central incisors (33%); dentine lesions in lower first molar (27%). One fourth of the participants had erosive wear into dentine, significantly more in males than in females (p = 0.047). More participants with erosive wear had decreased salivary flow during exercise compared with the non-erosion group (p
A questionnaire was given to representative samples of Norwegian recruits in 1990 and 1999 to explore dental health habits, history of gastroesophageal disorders and diet with possible relations to dental erosion. The samples were 792 (mean age 20.9 years) and 676 (mean age 21.6 years), respectively, and the corresponding responses were 62% and 100%. Minor differences in self-reported dental health habits and gastroesophageal disorders were found. The respondents' dentists had provided information about dental erosion for 8.2% of the respondents in 1990 versus 14.5% in 1999. There was an increase in the reported frequency of daily intake of juice from 17% to 24% (P = 0.006) and carbonated soft drink from 54% to 61% (P = 0.025) in the period 1990-99. The frequency of training activity showed minor changes, but in 1999 it was more common to drink during exercise (94% versus 74% in 1990, P
Dental erosion is caused by dietary or gastric acid. This study aimed to examine the location and severity of tooth erosion with respect to causative factors, and to determine whether the clinical pattern of erosion reflected the dominant etiological factor. The study involved 249 Icelandic individuals and included: a detailed medical history; clinical oral examination; salivary sampling, and analysis for flow rate, pH, and buffering capacity. Reflux was assessed in 91 individuals by gastroscopy, esophageal manometry, and 24-hour esophageal-pH monitoring. Reflux symptoms were reported by 36.5% individuals. Manometry results were abnormal in 8% of study participants, abnormal esophageal pH in 17.7%, and a pathological 24-hour pH recording in 21.3%. 3.6% were positive for Helicobacter pylori. Normal salivary flow was found in 92%, but low salivary buffering (10.4%) was associated with erosion into dentin (P
