A 19-month-old spayed female Burmese had recently been treated for epiphora. During that clinical examination, the referring veterinarian noticed moderate gingivitis and calculus accumulation. On referral to CADS, bilateral supernumerary (SN) maxillary fourth premolar teeth were diagnosed (), with associated stage 3 periodontal disease (PD3). SN 108 and SN 208 were positioned palatal to the normal maxillary fourth premolar teeth. The supernumerary teeth were orientated in the same manner as the normal teeth; that is, the mesiobuccal and distobuccal roots were buccally situated and the mesiopalatal root, palatally situated (). PD3 was also diagnosed at 206, 209, 302, 401 and 402, and tooth resorption (TR) at 309 and 409. Closed extraction of 206, 209, 302, 401 and 402 was performed, without elevating a mucogingival flap, while open extractions were performed on SN 108, SN 208, 309 and 409 (), by elevating a mucogingival flap. The SN 108 and SN 208 surgical sites were not sutured closed and 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.
