“…Manifest proximal caries was defined as "a caries lesion that clearly extends into the dentine". The bitewings were analysed by two of the authors by using a viewing box and binoculars according to Mattsson [21].…”

Objective. The aim of the present study was to investigate oral health and its determinants in 3-and 6-year-old children with asthma. Methods and Subjects.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.Results. The mean dfs (± standard deviation) in the 3-year-olds 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-olds were 2.5 ± 3.9 and 1.8 ± 2.8. The 3-year-old asthmatic children had more gingival bleeding than healthy controls (P < 0.05). There were no significant differences in gingivitis in the 6-year-olds.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). Conclusion.The results indicate that pre-school children with asthma have higher caries prevalence than healthy children. The factors discriminating for caries in asthmatic children are higher intake of sugary drinks, mouthbreathing and immigrant background.

Objective: To evaluate if prematurely born children have higher prevalence of malocclusion traits and greater orthodontic treatment need than matched full-term born controls. Materials and Methods: Seventy-three preterm children were selected from the Medical Birth Register and divided into two subgroups according to their gestational age. One group consisted of 37 very preterm children (VPT), born in gestational week 29-32, and the other of 36 extremely preterm children (EPT), born before the 29th gestational week. The subjects were compared with a control group of 41 full-term children, who were matched for sex, age, and nationality. Data from clinical examinations, study casts, and panoramic radiographs were used to determine malocclusion traits. The dental health component of the index of orthodontic treatment need (IOTN) was used to rank the treatment need. Results: Two or more malocclusion traits occurred significantly more often among EPT (83.3%) and VPT children (73.0%), compared with the full-term children (51.2%). Significantly higher prevalence of deep bites and was found in EPT and VPT groups compared with the full-term control group. Deep bite was the most common malocclusion trait in the EPT and VPT group. Higher orthodontic treatment need was found for the preterm children but no differences in prevalence of malocclusion traits and treatment need were found between VPT and EPT children. Conclusion:The clinician should be aware of the potential for a higher number of malocclusion traits and greater orthodontic treatment need in prematurely born children compared with full-term children.

Detection of Approximal Caries in 5-Year-Old Swedish Children

et al. 2005

The aim was to assess how accurately some commonly used risk factors/risk markers (predictors) for caries development could identify children with and without approximal caries as judged from bitewing radiography. Two hundred and sixty-seven consecutive 5-year-old children from two Swedish cities participated. Three experienced dentists examined the children. The predictors were the overall dmfs (decayed, missing and filled surfaces) value (canines and molars), the number of occlusal dmfs, the frequency of intake of between-meal sugary products, visible plaque on free smooth surfaces of second primary molars, toothbrushing habits and (before bitewing examination) an overall judgement by the examining dentist. The mean dmfs value without bitewing examination was 0.40 (SD = 1.22). Twelve percent of the children had at least one dentin lesion and 33% at least one enamel lesion that were detected from bitewing examination only. The gain from adding bitewing examination to clinical examination amounted to a mean of 1.2 approximal enamel and/or dentin lesions. The ability to correctly identify children with approximal caries from the predictors was limited; sensitivity ranged from 0.27 to 0.75 and specificity ranged from 0.41 to 0.93. The single best predictor was the dentist’s overall judgement with an average precision of 73%; average sensitivity for the presence of enamel and dentin lesions was 0.48 and for the presence of dentin lesions 0.66. The rest of the predictors added little to the predictive power. It is concluded that 33% of the 5-year-olds, representing a low caries prevalence population, benefited from bitewing examination. The ability to identify these children from the predictors was, however, limited.
