[Evaluation of clinical efficacy of casting pure titanium ring on reparation of subgingival residual root].
OBJECTIVE
To explore treatment regime and curative effect of the casting pure titanium ring on reparation of subgingival residual root.


METHODS
Thirty-two teeth were selected for reparation of subgingival residual root after root canal therapy in our department during 2008-2010. The teeth were restored with casting pure titanium ring, glass fiber post and all-ceramic crown. The patients were recalled 12 and 24 months after placement of the pure titanium ring. Gingival crevicular fluid(GCF) samples were collected by filter paper strips. Then the weight of GCF was detected and the gingival index was recorded. The data was analyzed for paired samples t test by SPSS17.0 software package.


RESULTS
There was no significant difference in the weight of GCF and the gingival index before and after placement of pure titanium ring (P<0.05).


CONCLUSIONS
By using pure titanium ring, most subgingival residual root after root canal therapy can be rehabilitated and function well for long time.
