Methods: a descriptive study, case compilation with a sample of 53 teeth in 19 patients between the ages of 12 and 38 years of age. The average age was 22, 9 years (SD=7,8), distribution by gender was 11 males and 8 females. Sensitivity evaluation was performed with cold test and it was done pre-test and post-test at 15, 30, 60, 90 and 180 days. The inclusion criteria were: maxillary cysts which due to their expansion and growth, involved vital teeth, dental organs whose apical area was radiographically compromised in the maxillary cysts and maxillary cysts of low relapse. Sensitivity was evaluated by means of a cold test before and after the intervention and osseous repair was measured in millimeters using positioners and a millimeter grid adhered to the radiographic film. In order to compare the measurements before and after enucleation for sensitivity and radiographic diameter, the paired student test with a level of significance of 0.05, was used.
Results: the 53 dental organs maintained sensitivity after enucleation, showing a tendency towards decrease of response time to cold after the intervention. Only one tooth did not respond during the pre-test evaluation, however, 15 days later, there was a positive response. The size of the osseous defect during the radiographic control evaluations showed decrease during follow up.
Conclusions: It can be concluded from the results obtained that there is a positive response to pulp sensitivity tests in teeth whose periapical area was radiographically compromised with the cystic lesion, which must be considered in order not to proceed with endodontic treatment.
