[Effect of occlusal therapy with FRC splint on periodontal parameters in maintenance phase]

The purpose of this study was to evaluate the changes of the periodontal parameters of mobile, but splinted teeth with intracoronal fiber reinforced composite and compare to non-mobile teeth in maintenance phase. We splinted 73 teeth (29 non-mobile, 44 mobile) in 18 cases. The periodontal parameters - probing depth, gingival index (Loe-Silness, 1964), plaque index (Silness-Loe, 1965) - were monitored clinically immediately, 1 year and 2 years after complete periodontal treatment. There were scored 69 treated teeth after 1 year and 37 treated teeth after 2 years. Statistical comparisons were performed using Wilcoxon test for two related parameters and Mann-Whitney U test for two independent parameters in the software package SPSS 11.0 for Windows (SPSS, Chicago, IL, USA). There was not mobility recorded at splinted teeth neither after treatment immediately nor at recall visits. The periodontal parameters demonstrated no significant changes of probing depth (-0,08 +/- 0,41, 0,05 +/- 0,51) and gingival index (-0,32 +/- 0,79, -0,32 +/- 0,75) 1 and 2 years after complete therapy. There was significant decrease in plaque index (-0,77 +/- 0,43, -0,36 +/- 0,55) measured at recall visits. No significant differences were detected between the mobile and the non-mobile groups in all parameters. No significant correlation between changes of gingival index and plaque index was determined. The intracoronal FRC splint do not obstruct the individual and professional oral hygiene. The stabilize of mobile teeth allow the same healing like a non-mobile teeth.
