Background: Evidence on the possible influence of social and psychosocial factors on gingival status in socially disadvantaged children is scarce. The aim of this study is to assess the relationships among socioeconomic status, pattern of dental visits, self-esteem, oral health beliefs, toothbrushing frequency, oral hygiene effectiveness, and gingivitis in low social status adolescents.
Methods: A cross-sectional study was performed involving 406 12-year-old students recruited in Manaus, Brazil. Socioeconomic status (family income, parent's schooling, number of goods, and household crowding), self-esteem, oral health beliefs, and frequency of toothbrushing were collected through self-completed questionnaires. Gingival status (bleeding on probing) and oral hygiene effectiveness (dental calculus) were evaluated by calibrated dentists through oral examinations. Structural equation modeling assessed the direct and indirect relationships between variables guided by a theoretical model.
Results: The prevalence of gingivitis was 77.6%. Worse socioeconomic status and poor oral hygiene effectiveness directly predicted gingival bleeding. Socioeconomic status was also linked to toothbrushing frequency. Positive oral health beliefs and higher self-esteem predicted higher frequency of toothbrushing. The latter was directly linked to greater oral hygiene effectiveness. Oral health beliefs and self-esteem indirectly predicted gingival bleeding via toothbrushing frequency and oral hygiene effectiveness.
Conclusion: The present findings suggest the importance of socioeconomic status and psychosocial factors on gingival status in underprivileged adolescents. Poor oral hygiene mediated the associations between psychosocial factors and gingival status.
