- Prevalence of dental caries and fissure sealants in a portuguese sample of adolescentsPublication . Veiga, Nélio J.; Pereira, Carlos M.; Ferreira, Paula C.; Correia, Ilídio J.Introduction: The aims of this study were to assess the prevalence of dental caries and the DMFT index, as well as the distribution pattern of pit and fissure sealants on permanent teeth in a Portuguese sample of adolescents, and to assess whether the existing usage of sealants and socio-demographic factors are correlated to caries prevalence on the examined sample. Materials and Methods: A cross-sectional study was designed with a sample of 447 adolescents aged 12 to 18 years old, attending a public school in Sátão, Portugal. A self-administered questionnaire with questions about oral health behaviours and socio-economic status was answered by adolescents in the classroom. Clinical examination of oral health status and assessment of fissure sealants were accomplished by only one trained member of the research team. Results: We obtained a DMFT index of 3.32 (2.92), which indicates a moderate level of prevalence of dental caries. When considering a DMFT=0, we found significant statistical differences between the parents´ level of education (≤ 4th grade=26.3 vs 5th-12th grade=18.8 vs >12th grade=43.3, p=0.001), gender (male=27.3 vs female=19.6, p=0.04), age (≤15 years=27.1 vs >15 years=18.5, p=0.02), presence of fissure sealants (yes=30.6 vs no=13.5, p=0.001) and experience of dental pain (no=25.4 vs yes=16.8, p=0.02). When analyzing the prevalence of fissure sealants, we verified that 58.8% of adolescents had at least one fissure sealant applied. Significant statistical differences were found when analyzing the presence of fissure sealants related with parents´educational level (>9th grade, OR=1.56 CI95%=1.05-2.54), gender (female, OR=1.86 CI95%=1.19-2.98), experience of dental pain (yes, OR=0.62 CI95%=0.39-0.97) and presence of dental caries (yes, OR=0.35 CI95%=0.19-0.65). Conclusions: The moderate level of caries prevalence reveals the need of improvement of primary prevention interventions among Portuguese adolescents. The establishment of a more targeted preventive program with better and more effective oral health education is essential, having into account socio-demographic aspects.
- Quality of life, sleepiness and depressive symptoms in adolescents with insomnia: A cross-sectional studyPublication . Amaral, Maria Odete Pereira; Garrido, António José de Almeida; Pereira, Carlos de Figueiredo; Veiga, Nélio; Nunes, Carla de Rosário Delgado; Sakellarides, Constantino TheodorObjectives: To determine the prevalence of insomnia in a sample of Portuguese adolescents and assess its repercussions on HRQoL, daytime sleepiness and depressive symptomatology. Design: We carried out a cross-sectional school-based study evaluating students from Viseu. Location: Students from twenty-six public secondary schools in the county of Viseu, Portugal. Participants: Of 9237 questionnaires distributed, 7581 were collected (82.1%). We excluded from analysis all questionnaires from adolescents younger than 12 or older than 18 years of age (211) and unfilled forms (451). The sample comprised 6919 adolescents, the 7th to 12th grade, from 26 public secondary schools. Interventions: None. Measurements: Data gathering was done using a self-applied questionnaire. Insomnia was defined based on the Diagnostic and Statistical Manual of Mental Disorders -- IV criteria. HRQoL was evaluated with the Quality of Life Health Survey SF-36, depressive symptomatology with BDI-II and daytime sleepiness with the Epworth Sleepiness Scale. Results: Prevalence of insomnia was 8.3% and the prevalence of adolescents with symptoms of insomnia without daytime impairment (disturbed sleepers) was 13.1%. HRQoL was significantly reduced among adolescents with insomnia compared to normal sleepers (p < 0.001) and even when compared to disturbed sleepers (p < 0.001). There was an increase in daytime sleepiness from normal sleepers to disturbed sleepers and to adolescents with insomnia (p < 0.001). There was also an increase in the prevalence and severity of depressive symptoms (p < 0.001). Conclusions: Our results show that insomnia is associated with a significantly lower health related quality of life among adolescents.
