Impacto de condições bucais na qualidade de vida de indivíduos portadores de lúpus eritematoso sistêmico

Abstract

The present cross sectional study aimed to evaluate the impact of oralconditions on the quality of life of individuals with Systemic Lupus Erythematosus (SLE). A sample of 75 patients with SLE under surveillance at the Department of Rheumatology of the Federal University of Minas Gerais was evaluated. The study also included a control group of 78 individuals, who, according to self-report, did not present any disease..Individuals' oral health-related quality of life (OHRQoL) wasevaluated through the Brazilian version of the questionnaire Oral Health Impact Profile (OHIP-49). All the participants were submitted to dental examination. Dental caries was assessed by means of the DMFT index and the periodontal condition was evaluated through criteria previously established that considered probing depth. Measures of sialometry, sociodemographic characteristics, and oral hygiene habits were also collected. Individuals of the SLE group were evaluated in terms of disease activity (SLEDAI) and disease damage (SLICC/SDI). The responses to categorical questions for each group were compared using the Chi-square test. The responses to continuous variables for each group were compared using Mann-Whitney test. The Mann-Whitney test was also used to evaluate differences in the subscale and overall OHIP scores between the SLE group and the Control group and between the different SLEDAI and SLICC/SDI categories in the SLE group. For the overall score, the level of significance was set at p<0.05. For the subscales, the Bonferroni correction was used and p values <0.007 were considered statistically significant. The results demonstrated that individuals of the SLE group presented a higher negative impact of the oral conditions on the quality of life when compared with the individuals of the control group (p=0,011). The determinant of the negative impact was prosthesis wearing (p<0,05). In the SLE group, it was also observed that individuals with a moderate damage presented worse OHRQoL when compared with individuals without damage (p=0,043). Awareness of the impact of oral conditions on the quality of life of individuals with SLE may be useful to improve the multidisciplinary treatment of this group of patients.
