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 ().
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.
