【 摘 要 】

Abstract Background Oral health-related quality of life (OHRQoL) has important implications for the clinical practice of dentistry and dental research and should contribute to professional judgment about restorative treatments and prosthetic replacement in patients who had reduced dentitions. The aim was to compare the OHRQoL among adults (35–44 years) categorized according to different definitions of reduced dentition and considering the use (or non-use) of dental prosthesis. Methods This study used data from a probabilistic sample of adults in Sao Paulo, Brazil, 2015. OHRQoL was based on none items of Oral Impacts on Daily Performance (OIDP) index, as prevalence (at least one impact) and extent (the number of items with non-zero score). We used different criteria to assess dentition status: (1) Shortened Dental Arch (SDA): having 3–5 natural occlusal units (OUs) in posterior teeth and intact anterior region; (2) hierarchical functional classification system: a five-level stepwise classification of dentition; and (3) presence of ≥21 teeth. The use or nonuse of dental prosthesis was recorded. Negative binomial regression models involved the adjustment for social determinants of health. Results Nearly half (53.1%) of the 5753 participating adults had at least one oral health issue impacting OHRQoL. OIDP prevalence in adults with SDA did not differ from those with more OUs (PR = 1.02; 95%CI 0.91–1.13). Individuals with non-functional dentition had worse OHRQoL regardless of their use of a dental prosthesis. Adults with fewer than 21 remaining teeth, ranked significantly higher in OIDP extent, regardless of dental prosthesis use (PR = 1.38; 95%CI 1.16–1.63 with prosthesis; PR = 1.62; 95%CI 1.19–2.20 without dental prosthesis). Conclusions Individuals with more missing teeth reported worse OHRQoL regardless of using a dental prosthesis. Preserving a functional dentition, even with missing teeth, is compatible with OHRQoL.
