Abstract
BackgroundThere are scarce evidences that evaluated the impact of periodontal disease on oral health-related quality of life (OHRQoL) taking marginal gingival alterations into consideration. Thus, this study aimed to verify the association between OHRQoL and gingival enlargement and gingival bleeding in subjects under fixed orthodontic treatment (FOT).Methods330 participants under FOT for at least 6 months were examined by a single, calibrated examiner for periodontal variables and dental aesthetic index. Socio-economic background, body mass index, time with orthodontic appliances, and use of dental floss were assessed by oral interviews. OHRQoL was evaluated using the oral health impact profile (OHIP-14) questionnaire. The assessment of associations used unadjusted and adjusted Poisson regression models.ResultsHigher impacts on the OHIP-14 overall were observed in subjects who presented higher levels of anterior gingival enlargement (RR 2.83; 95% CI 2.60-3.09), were non-whites (RR 1.29; 95% CI 1.15-1.45), had household income lower than five national minimum wages (RR 1.85; 95% CI 1.30-2.61), presented body mass index > 25 (RR 1.14; 95% CI 1.01-1.29), and showed a dental aesthetic index > 30 (RR 1.32; 95% CI 1.20-1.46).ConclusionsAnterior gingival enlargement seems to influence the OHRQoL in subjects receiving orthodontic treatment.
Highlights
There are scarce evidences that evaluated the impact of periodontal disease on oral health-related quality of life (OHRQoL) taking marginal gingival alterations into consideration
This study aimed to evaluate the independent associations between OHRQoL and gingival enlargement and gingival bleeding
Considering the periodontal diagnosis, based on patient ages and periodontal data explored in another study [28] (2,06 mm ± 0,18 and 1,6 ± 0,11 for mean probing depth and clinical attachment levels in proximal sites, respectively) most patients have only periodontal diagnosis of gingivitis
Summary
There are scarce evidences that evaluated the impact of periodontal disease on oral health-related quality of life (OHRQoL) taking marginal gingival alterations into consideration. This study aimed to verify the association between OHRQoL and gingival enlargement and gingival bleeding in subjects under fixed orthodontic treatment (FOT). Oral health-related quality of life (OHRQoL) is defined by self-reports pertaining to oral health, capturing both the functional, social and psychological impacts of oral disease [2]. Oral epidemiology has used indices to assess the self-reporting of OHRQoL issues as adjuncts to clinical examinations, thereby documenting the full impact of oral disorders. The OHIP14 is one of these instruments; it has been widely used in several cross-sectional and longitudinal studies including adolescents [4] and young adult [5] populations under orthodontic treatment. The questionnaire was developed in Australia [6], but further studies confirmed its validity and reliability in Brazilian population [7]
