Résumé : AbstractPurpose To compare oral health [dental caries, periodontal status, and erosive tooth wear (ETW)], diet and oral hygienehabits between obese and normal weight adolescents, and to explore possible risk associations.Methods In this case–control study, a convenience sample of 71 obese adolescents (age range 11–18) from a rehabilitationcentre, and 54 age-sex-matched normal weight adolescents were selected for this study. Groups were defined using theBody Mass Index and growth curves for Flemish adolescents. Oral health was measured using DMFT, gingival, plaque andBEWE index. A validated questionnaire was utilized to assess diet and oral hygiene habits. Mann–Whitney U test was usedto compare oral health between groups. Multivariate Firth’s logistic regression analysis, conditional regression analysis andclassification trees were used to detect associations between oral health and potential risk factors.Results Prevalence of ETW did not differ significantly between groups, although obese adolescents presented a significantlyhigher caries experience, gingivitis, presence of plaque and periodontal problems, compared to normal weight adolescents.After adjusting for age and sex, obesity was associated only with the presence of dental plaque (p ≤ 0.001). Obese participantsreported a significantly higher intake of sugar-rich and caloric food items than normal weight group. The consumption ofacidic drinks, however, was similar.Conclusion Obese adolescents presented significantly higher caries experience, gingivitis and plaque, although after adjusting,obesity became significantly associated only with the presence of dental plaque.
