A 6-year-old castrated male Burmese was presented as the referring veterinarian had noted supernumerary teeth on oral examination. On referral, SN 108, SN 308 and SN 408 were confirmed. The SN 408 was shown to have a supernumerary third root on radiographs. The supernumerary root was slender and situated between the mesial and distal roots (). The SN 108 was positioned palatal to the normal 108 () and the SN 308 and SN 408 were positioned lingual to the normal mandibular fourth premolar and molar teeth, causing moderate rotation of the adjacent normal mandibular teeth; 108, 109, SN 108, SN 308 and SN 408 were affected by PD3. Closed extraction was performed at 109. The open extraction technique was used for the extraction of SN 108, SN 308, SN 408 and 108.
Case 2. A male, leucoderma, Brazilian patient, aged 9 years and 11 months, presenting Class 3 malocclusion, sought a private clinic for orthodontic treatment, which was planned in two phases (interceptive and corrective), to be completed with orthognathic surgery. Similarly to Case 1, the initial panoramic radiographs revealed no abnormalities in the dentition (Figures and ).\nIn the first phase of the orthodontic treatment, a modified HAAS expander associated with a facial mask was used for 8 months. Two years later, a new expander and facial mask were recommended for further 6 months.\nDuring the planning of the second phase of the treatment, with complete permanent dentition, an orthodontic/surgical approach was deemed necessary after facial growth had been completed. When additional tests were performed, the radiographic follow-up revealed the presence of three supernumerary teeth in the premolar region (Figures and ). Surgical removal of all third molars as well as the 3 supernumerary teeth was performed in a hospital setting under general anesthesia, along with the surgery for the correction of deviated nasal septum ().\nAt 20 years and 5 months, during orthognathic surgery planning, a new radiographic image showed a supplemental supernumerary tooth in the left mandibular premolar region (), which was also surgically removed.
