Impacto da disfunção temporomandibular sobre os custos de saúde e perda de produtividade no Brasil

Abstract

Temporomandibular Disorder (TMD) negatively impacts quality of life, healthcare systems, and population productivity. Accordingly, this study aimed to estimate the social costs of TMD in Brazil between the years 2018 and 2023. Healthcare costs were analyzed based on data from the Outpatient Information System (SIA) and the Hospital Information System (SIH). Productivity loss due to absenteeism was determined using data from the National Institute of Social Security (INSS), based on ICD-10 code K07.6. Total costs were estimated by year, sex, age group, geographic region, and state. Productivity loss was assessed using a generalized linear model with Gamma regression, considering days of work leave and costs, with a significance level of 5%. The total cost of TMD amounted to BRL 13,274,921.75 (USD 5,508,266.29), with 62% attributed to absenteeism (BRL 8,232,834.35 / USD 3,416,113.84). The Southeast Region accounted for the highest expenditures. Women presented higher healthcare costs, more days of work leave, and greater absenteeism. Absenteeism costs were associated with age, and individuals living in rural areas showed lower values. The data highlight the need to structure a healthcare network for patients with TMD in the country.
