Influence of oral health and hygiene on state of FPDs

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
