title: Evaluation of dental material series from patients with dental prostheses and suspicion of delayed hypersensitivity.
abstract: BACKGROUND
  Patients with oral sensitivity are common in our practice. Allergic contact dermatitis is one of the most frequent etiologies.
  
  
  OBJECTIVE
  Evaluate oral contact dermatitis using the Brazilian standard series and complementary dental series in patients using dental prostheses, with or without oral complaints. Determine specific dental Brazilian series.
  
  
  METHODS
  Patients using dental prostheses with or without oral complaints realized patch tests. Brazilian standard series and complementary dental series were used according to ICDRG recommendations. The results were analysed according to age, sex, race, atopic conditions and symptoms associated.
  
  
  RESULTS
  From 54 patients tested, 34 (63%) were positive at least to one substance. Nineteen had oral complaints, such as burning mouth, itch or oral erythema. There was no association between atopic condition and tests results. Without the oral series, just 23(42,6%) patients had a positive result. Using the Brazilian standard series with the complementary dental series we improved the positivity of the patch test to 47%.
  
  
  CONCLUSIONS
  In patients using prostheses and with oral complaints, patch tests with Brazilian standard series with complementary dental series improve the tests positivity.
