An 8-year-old spayed female Burmese displayed sudden onset clinical signs of pawing at its face, mildly traumatising its left lip. On oral examination, an SN 208 was found palatal to the normal left maxillary fourth premolar tooth (). The supernumerary tooth was situated in a reverse and mirror position to the normal 208, so that the distal root was positioned mesially, the mesiopalatal root positioned palatodistally and the mesiobuccal root positioned adjacent to the normal 208 distal root. PD3 was diagnosed at 108, 109 and 208, and TR of 309. Closed extraction was performed at 109. The SN 208, as well as 108, 208 and 309, were extracted using the open extraction technique. The SN 208 extraction site was allowed to heal by second intention. The owner stated at the follow-up consultation that the cat did not paw at its face again after the surgery
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.
