    Periprosthetic joint infection (PJI) occurs in 0.5%-2% of primary arthroplasties and 15%-36% of revision cases.

  • 2

    Oral and dental conditions may serve as extra-articular infection sources, potentially contributing to up to 10% of late PJIs.

  • 3

    The clinical significance of dental foci in PJI is uncertain, with mixed opinions on the necessity of routine dental assessments.

  • 4

    This study aimed to determine the prevalence of dento-alveolar foci in PJI patients and compare clinical outcomes based on dental status.

  • 5

    The analysis included 213 PJI cases, with a mean patient age of 71.9 years, predominantly involving hip infections.
