title: [Study of 103 cases of odontogenic cysts].
abstract: OBJECTIVE
  To describe characteristics of odontogenic cysts in a Mexican population.
  
  
  METHODS
  A retrospective study of 103 odontogenic cysts in 86 patients was done. The data were obtained from files of the Pathology Department of a General Hospital.
  
  
  RESULTS
  We observed a frequency of the 8.13 % of odontogenic cysts (103) in 1266 pathological studies. The dentigerous cyst 56 % and odontogenic keratocyst 33 % were the most common odontogenic cysts. Sixty one percent of the cysts appeared in the second and third decades of life. In 71 cysts, 42 % appeared in the posterior region jaw, 29 % in the anterior region of the maxilla and 21 % in the posterior region of the maxilla. A 6.7 % developed a recurrence after treatment and a case of keratocyst of posterior region of the maxilla was associated with epidermoid carcinoma. The study included three women with the syndrome of carcinoma of the basal cell nevus, who presented multiple keratocysts.
  
  
  CONCLUSIONS
  The dentigerous cysts and odontogenic keratocysts were the most frequent odontogenic cysts. They appeared mainly in the second and third decades of life.
