SUPERNUMERARY TEETH
Comparison of facial swelling in different ambulant types showed that the normal incidence of swelling at 24 h and 72 h after treatment was significantly higher in the piezosurgery and combined piezosurgery groups than in the HSCAH group, while the incidence of severe swelling was significantly lower in the extraction of inverted and horizontally embedded supernumerary teeth. In the extraction of oblique and orthodontic embedded supernumerary teeth, the normal incidence of swelling at 24 h postoperatively was higher in the piezosurgery group than in the HSCAH group, and the normal incidence of swelling at 72 h postoperatively was significantly higher in three groups, whereas the incidence of severe was significantly lower. Comparison of facial swelling in different ambulatory locations revealed that in embedded supernumerary teeth with root tips extracted, the normal incidence of swelling was higher in the piezosurgery group than in the HSCAH group at 24 h postoperatively, while the proportion of patients with severe incidence was lower than in the HSCAH group, and the normal incidence was significantly higher and the severe incidence was significantly lower in all three groups at 72 h postoperatively. In the middle and crown segments of the embedded supernumerary teeth, the normal incidence was significantly increased in all three groups at 24 h postoperatively, while the incidence of severe was significantly decreased.
