title: [Evaluation of the fiber-reinforced composite periodontal splint on fixing loose teeth with severe periodontitis].
abstract: OBJECTIVE
  To evaluate the clinical effects of fiber-reinforced composites for splinting loose teeth after periodontal treatment.
  
  
  METHODS
  Patients with severe periodontitis (104 teeth) were randomly divided into fiber-reinforced composites group (58 teeth) and wire-ligation fixation group (46 teeth). After periodontal treatment, the loose teeth were fixed by fibre reinforced composites and wire-ligation. After 1 year of clinical observation,probing depth(PD), attachment loss(AL), gingival sulcus bleeding index (SBI)and plaque index(PLI)were measured. The data was analyzed with SPSS13.0 software package.
  
  
  RESULTS
  Six months after fixation, PD and AL became shallower (P<0.05), however, no significant difference was observed in SBI and PLI in the experimental group. In the control group, PD and AL became shallower, SBI and PLI values were higher (P<0.05). SBI and PLI in wire-ligation fixation group were higher than that in fibre reinforced composites group six months after fixation (P<0.05).
  
  
  CONCLUSIONS
  High-strength fibers in the periodontal splint is effective for loose tooth fixation in patient with severe periodontitis.
