Aim to characterize oral health in adolescents with hypertension and evaluate presence of significant associations between hypertension and main dental diseases.MethodsA case-control study was conducted. A total of 130 subjects aged 10 -17 were included in the study. The group of ‘cases’ included 65 adolescents with hypertension, verified by ABPM, and control group included the same number of adolescents with normal blood pressure levels, compatible by the sex and age. All adolescents underwent anthropometric measurements with BMI calculation, dental examination (caries intensity index, gingivitis index, complex dental plaque index, oral hygiene index). Binary logistic regression, adjusted for BMI z-scores and oral hygiene indexes, was used to assess the relationship between hypertension and presence and severity of oral diseases in adolescents.ResultsFrequency of dental caries and periodontitis was higher in the group of adolescents with hypertension in comparison with the controls (76.9% vs. 49.2% for caries, and 40% vs. 9.2% for periodontitis, p=0.001 for both). Signs of moderate to severe gingivitis were noticed in 18.5% adolescents with hypertension and only in 3.1% adolescents from the control group (p=0.009). Poor oral hygiene was detected in 43.1% adolescents with hypertension and in 21.5% adolescents from the control group (p=0.002). Presence of hypertension was significantly associated with caries and periodontitis, but not with gingivitis in adjusted regression models (OR 3 [1.3 – 7.1], p=0.012 for caries, and OR 3.9 [1.4 – 10.5], p=0.007 for periodontitis). Moreover, hypertension was associated with more severe damage of periodontium (OR 3 [1.6 – 5.6], p=0.001).ConclusionResults of this study showed, that hypertensive adolescents have poorer oral health than adolescents with normal BP level. This substantiates the necessity of multidisciplinary approach to management of this group of patients with participation of both pediatric physicians and dentists.
