title: [Analysis of conservative therapies for posterior teeth with longitudinal fractures.].
abstract: OBJECTIVE
  To explore the ideal method for conservative therapies of posterior teeth with longitudinal fracture.
  
  
  METHODS
  The records of 297 cases undergoing conservative treatment of posterior teeth with longitudinal fracture were analyzed regarding to the position, etiology and the time of treatment from fracture and the causes of failure.
  
  
  RESULTS
  258 cases were conserved effectively and 39 cases were extracted due to failure.16 cases had failure 1 week after treatment. All the patients were followed up for 2 to 10 years, and the rate of success was 86.87%.
  
  
  CONCLUSIONS
  With fixed early and appropriate treatment, the teeth can be conserved effectively and exert good masticatory function .
