title: Temporomandibular disorders, headaches, and neck pain after motor vehicle accidents: a pilot investigation of persistence and litigation effects.
abstract: BACKGROUND
  There is a lack of long-term follow-up studies that involve post-motor vehicle accident temporomandibular disorders and compensation.
  
  
  OBJECTIVE
  The purposes of this retrospective pilot study were (1) to assess patients who had previously been treated for temporomandibular disorders after motor vehicle accidents to determine the nature of their symptoms in terms of jaw, head, and neck pain and jaw dysfunction and (2) to determine whether there was a difference in the pain and dysfunction between those who had settled and those who had not settled their insurance claims.
  
  
  METHODS
  Thirty previously treated patients with temporomandibular disorders after motor vehicle accidents were questioned by telephone regarding litigation status and current jaw, head, and neck pain and jaw dysfunction symptoms. They did not differ substantially from a smaller group who were not able to be interviewed. Descriptive statistics were calculated and statistical tests were performed. A total of 22 patients had their claims settled.
  
  
  RESULTS
  Approximately three fourths had persistent complaints of jaw pain, jaw dysfunction, and headache, and more than 80% reported persistent neck pain. No apparent differences were found between those who had and had not settled their insurance claims.
  
  
  CONCLUSIONS
  Jaw, head and neck pain, and jaw dysfunction continued to be problems for the majority of this patient population, regardless of litigation status in this retrospective study.
