Abstract:
The objective of the present study was to compare the acceptability
and effectiveness of topical anesthesia and infiltration anesthesia for insertion
of orthodontic mini-implants used as temporary anchorage devices. The
sample comprised 40 patients, 17 males and 23 females, mean age 26 years
and all were in orthodontic treatment and needed anchorage. In all individuals
were installed mini-implants in the maxilla bilaterally, in one side with
infiltration anesthesia and opposite with topical anesthesia. These 40 patients
completed two questionnaires, one before and another after the insertion, the
pain measurement was made through a visual analog scale (VAS). The
collected data were analyzed using descriptive statistics and the pain
measurements were compared using nonparametric test of Mann Whitney.
The results found that 60% of the patients felt more comfortable because of
the use of topical anesthesia for the insertion of mini-implants, 72.5% of the
patients described the pressure during insertion of the anchorage device as
the most unpleasant sensation at all the process, 62.5% of patients felt more
pain with the use of topical anesthesia. The study concluded that patients had
less pain with the use of infiltration anesthesia, and also preferred this type of
anesthetic.
