This study aimed to translate, culturally adapt, and validate the \"Oral Health Values Scale\" (OHVS) for use in the Croatian context. <b>Methods:</b> The process involved two key phases. First, an expert committee oversaw the translation to ensure consistency across all versions and produce a test-ready instrument. To identify any ambiguities in translation and test the instrument's reliability, a pilot study with 40 participants was conducted. Once the expert committee confirmed content validity, the finalized OHVS was administered to a sample of 702 Croatian adults to evaluate its psychometric properties. <b>Results:</b> Factor analysis revealed a three-factor structure in the Croatian version, differing from the original four-factor model, with items from the \"Retaining Natural Teeth\" subscale distributed across two factors.
