The objective of this retrospective clinical study was to determine the frequency and pathogenicity of unintentional retained tooth root fragments after extraction of the maxillary fourth premolar (108 and 208) and mandibular first molar teeth (309 and 409) in 74 canine and 42 feline client-owned patients. Radiographs of client-owned animals with historical evidence of extraction of teeth 309 and 409 were reviewed. All patients had dental extraction(s) for clinical reasons, and all extractions were deemed successful by the practitioners. Extraction sites were radiographed to identify tooth root fragments and pathology. Twenty-five canine and 25 feline patients that had extractions utilizing preoperative and postoperative radiography were also included. Sixty-one of 74 canine patients (82.4%; P < 0.0001) and 39 of 42 feline patients (92.8%; P < 0.0001) had evidence of retained tooth root fragments. In total, 100 of 116 cases (86.4%; P < 0.0001) had retained tooth root fragments, and periapical pathology was found in 66 of 116 (56.8%; P = 0.000000743) radiographs, including 39 of 74 canine cases (52.7%; P = 0.00002765) and 27 of 42 feline cases (64.3%; P = 0.01589). The control group had no evidence of retained root fragments. Further veterinary dental training and routine use of pre- and postoperative dental radiology are recommended.
