Periodontal health in patients with fixed prosthesis according to the regularity of supportive periodontal therapy in Zagreb (Croatia)

The importance of supportive periodontal therapy (SPT) for teeth with fixed partial dentures (FPD) has been well known for years. Therefore, the aim of this research was to establish the condition of periodontium of teeth with FPD and non-abutment teeth according to the regularity of SPT. The research comprised 109 patients with existing FPD. Patients were classified into 3 groups due to regularity of their SPT– without SPT, irregular (less than one appointment a year) and regular (at least 1 appointment per year). 600 abutment and 1623 non-abutment teeth were examined. Periodontal probe (PCP-11), periodontal indices (PI, BOP, PD, AL, and recession), periodontal charts and questionnaires were used. Statistical analysis was performed with SPSS 15.0 (Windows), using quantitative comparisons with the ANOVA test. An odds value (P) below 0.05 was considered a statistical significant difference. The majority of patients (43%) underwent regular SPT ; 39 % underwent irregular SPT and 18% underwent no SPT at all. Abutment teeth had statistically higher values of PD (4.16 mm ; P = 0.03) and CAL (4.53 mm ; P = 0.001) in a group that never underwent SPT after FPD was fabricated in comparison to other two groups. Non-abutment teeth had statistically higher values of recession (1.06 mm ; P = 0.003) and CAL (3.93 mm ; P = 0.001) in a group that had irregular SPT in comparison with regular SPT group. We can conclude that even irregular SPT in patients with FPD can improve periodontal health of abutment teeth.
