Abstract
Our aim was to compare the use of a conventional rotary handpiece and a Piezosurgical
unit for extraction of lower third molars. We studied 40 patients, who were allocated
alternately to have the third molar removed with either the handpiece or the Piezosurgical
unit. Pain, trismus, and oedema were evaluated at baseline and then postoperatively,
together with paraesthesiae, on postoperative days 1, 3, 5, 7, and 15. Damage to surrounding
tissue was checked on the same day whereas dry socket was evaluated from postoperative
day 3 onwards. More patients complained of pain in the conventional group, they also
required more analgesics, and they developed trismus more often than in the Piezosurgery
group. There was also significantly more postoperative swelling in the conventional
group. Patients were also evaluated using the subjective Postoperative Symptom Severity
(PoSSe) scale. Our results suggest that apart from some inherent limitations with
the Piezotome, it is a valuable alternative for extraction of third molars.
