Abstract:
The objective of this study was to evaluate the efficiency of the use of topical
anesthetics for the insertion of mini-implants used as skeletal anchorage in
orthodontics. Besides, the presence of sexual dimorphism was evaluated regarding
the answers to the questionnaire. For this, the topical anesthetics based in lidocaine
20% manipulated gel was used to the insertion of the mini-implants in 40 patients in
treatment with fixed appliances, in the Dentistry Clinics at UNINGÁ. The mean age of
the patients was 23.58 years. Patients answered to a questionnaire with 4 multiple
choice and closed answer questions, evaluating the acceptability and discomfort of
the patients during anesthetics and placement of the mini-implant. Data were
evaluated by percentage and by the chi-square test to evaluate the sexual
dimorphism. Results showed that 92.5% of the patients reported that did not feel any
discomfort during the application of the topical anesthetics, and only 7.5% felt a slight
dormancy. In relation to the procedure of installation of the mini-implants, only 20% of
the subjects related pain (regardless of the intensity) as the more unpleasant
sensation during the procedure of placement of the mini-implant. However, 50% of
the patients did not feel any pain and only 10% of the subjects felt intense pain.
There was difference between sexes only regarding the more unpleasant sensation
during the procedure, and the majority of the female patients (55%) reported not to
feel any unpleasant sensation, comparing with only 40% of the male patients. It was
concluded that it is possible to accomplish the procedure of installation of the miniimplants
using only topical anesthetics.
