Abstract
Dental anxiety for unerupted mandibular third molars extraction in children under local anesthesia is a tricky problem. The purpose of this study was to compare psychological and physiologic findings of extractions of unerupted mandibular third molars in children by piezosurgery and conventional osteotomy. This prospective, single-center, double-blind study included children who required extraction of mandibular third molars under local anesthesia. All subjects were randomly divided into two groups: piezosurgery and conventional osteotomy (control). The primary outcome variables were dental anxiety assessed by the Modified Child Fear Survey Schedule Dental Subscale (CFSS-DS) and postoperative pain qualified by the visual analog scale (VAS). Secondary outcome variables included blood pressure, heart rate, saturation, and operation duration. The data were analyzed by t-test and chi-square test (P ≤ 0.05). All 40 study patients (37.5% males and 62.5% females with an average age of 14.43 ± 1.32years) completed the entire trial. There were no statistically significant differences observed between the two groups in terms of gender allocation, age, side of extraction, and Winter's Classification (P > 0.05). The operation duration of the piezosurgery group was significantly longer than the conventional osteotomy group (P < 0.01). The VAS scores showed that pain levels of children in the piezosurgery group were significantly less than the conventional osteotomy group on the first and third days postoperatively (P < 0.05 and P < 0.01, respectively). The CFSS-DS score in the piezosurgery group significantly decreased compared to the conventional osteotomy group (P < 0.05). Compared with the conventional osteotomy group, a significant decrease in heart rate, and lower systolic and diastolic blood pressures were observed after extraction in the piezosurgery group (P < 0.05 and P < 0.01, respectively). Compared with conventional osteotomy, piezosurgery can effectively reduce postoperative pain and have some effect in relieving dental anxiety for the extraction of unerupted mandibular third molars in children. Piezosurgery may be a viable technique for the extraction of unerupted mandibular third molars in children under local anesthesia.
