A 19-month-old spayed female Burmese, a littermate of case 1, was presented with a primary complaint of halitosis. Both cats were fed a raw diet and had not shown any changes in eating behaviour. Oral examination revealed bilateral supernumerary maxillary fourth premolar teeth and a supernumerary left mandibular fourth premolar tooth (SN 108, SN 208, SN 308), with associated PD3 and moderate generalised gingivitis. The supernumerary maxillary fourth premolar teeth were also situated palatal to their normal counterparts (), while SN 308 was moderately rotated and situated between 308 and 309 (). PD3 was also diagnosed at 209. Tooth 209 was extracted using the closed extraction technique, and SN 108, SN 208 and SN 308 were extracted using the open extraction technique (). The SN 108, SN 208 and 209 extraction sites were allowed to heal by second intention ().
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.
