Objective: The aim of the investigation was to evaluate the state of fixed prosthodontic dentures (FPD) relative to the oral hygiene habits and periodontal health in a population of a rural region in Croatia. Methods: Oral hygiene habits, dental status and periodontal health anamnesis were recorded in a group of 212 individuals with fixed prosthodontic dentures (mean age 41, 1 yrs, S.D. 18, 9) and in a control group of 47 individuals without FPDs, by trained examiners. The WHO Oral hygiene index and the CPI index were used in assessment of oral and periodontal health. State of FPDs was evaluated according to the CDA index for the crowns and bridges. Results: Oral hygiene habits were inadequate for the complete sample (91% examinees ≤ 2 brushing/day). Oral hygiene index showed poor results, with both groups having plaque formation and gingivitis. Spearman’ s correlation analysis showed significant correlation between the OHI index scores and CDA index values (rho=-0.468, p<0.01) as well as between the CPI and CDA indices (rho=-0.572, p<0.01), where lower OHI and CPI scores were correlated with poorer condition of FPDs. No significant difference was determined in OHI and CPI indices values between the control group and the group with FPDs (p=0.051). Conclusions: The results of the study point out to the insufficient preventive oral health care in the rural region, as well as to the insufficient self-perception on the proper oral hygiene maintenance, thus influencing the state of FPDs (p<0, 05).
