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.
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
