“…Some supernumerary cheek teeth are incidental findings on routine dental examinations. Disto-molars (a supernumerary cheek teeth triadan 12) are more frequently encountered in the maxilla than in the mandible, often bilaterally (Dixon et al, 2005b;Quinn et al, 2005;Dixon, 2011;Pasicka et al, 2017). Clinical signs of oral discomfort appear as dental overgrowths and periodontal disease secondary to food impaction develop (Dixon et al, 2005b;Quinn et al, 2005;Parés and Lozano, 2014).…”

Two horses were presented with problems during ridden exercise due to a firm, sensitive swelling at the level of the cheek adjacent to an upper Triadan 06. Oral, radiographic and computed tomographic examinations (n=1) identified the presence of a palatal supernumerary tooth being the causing factor of a buccally displaced 06. In both cases, the supernumerary tooth was extracted on the standing sedated horse. A couple of months following extraction, the buccally displaced tooth had spontaneously moved into a more physiological position due to orthodontic forces of the cheek and masticatory forces. Both horses uneventfully returned to ridden work without further problems.

“…Commonly applied research methods, used in both fields, involve zoological and anatomical identification of the remains of different animal species [ 1 , 2 , 3 ], assessment of paleopathological changes [ 2 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ], as well as taphonomic marks on bones, identification of sex, estimation of withers height [ 2 , 4 , 5 , 6 , 11 , 12 , 13 ], and determining the morphological type [ 2 , 4 , 5 , 6 , 7 , 14 ], season, and also the animal’s age at death. In fossil studies, it is important to determine the individual age of death of animals because of the utility of this information for, among other analyses, the estimation of mortality patterns (catastrophic profile and natural mortality profile).…”

The analyses were performed on a right third premolar (P3) of a white rhinoceros female (Ceratotherium simum, Burchell 1817). The specimen was born in captivity at London Zoo (Zoological Society of London), then in the 1970s transferred to Kiev Zoo (Peremohy Avenue), Ukraine, and was kept there until it died at a documented chronological age of 48 years. The female died because of its age, which indicates it was kept in good conditions adequate to the requirements of this species. Photographs and micrographs with radiological documentation were taken on the said tooth. Its structural characteristics were determined, and on the occlusal surface areas and points of anatomical constitution of its crown were identified. The tooth was also histologically evaluated via sections taken horizontally in a mesial-distal plane through the crown, horizontally in a mesial-distal plane through the coronal portion of the root, and longitudinally in a lingual-buccal plane through the crown and the root. Preparations with ground sections were made and observed in white, polarized, and reflected light. In the subsequent stage X-ray and SEM imaging has also been used, for analysis of the distribution of annual growth layers of mineralized dental tissues of cement and dentine, counted from the root canal center to the buccal surface. An attempt was also made to confirm the annual season in which the animal died, based on cement growth lines. It was observed that the growth lines were visible in all the analyzed sections, in dentine and cement. In the cement, the lines were relatively few and did not represent the attested age of the animal. The analysis of the coloration of the cement lines indicated that the animal was regularly fed a diet that was not seasonally differentiated. From the X-ray examination comes a conclusion that the animal did not suffer from periodontal diseases. Visible growth lines were observed on the dentine. On the horizontal section through the crown growth lines in the dentine were few and unclear. On the longitudinal section, both on the caudal and rostral roots, these lines were clearly visible and much more numerous than expected considering the known age of the animal, as more than 50 were counted. On horizontal sections through the upper part of both roots, distinct growth lines were observed in the dentine, and their number—48 for both roots—corresponded precisely to the age of the animal. The results of our study indicate that this method has significant potential for application to verify the age at death for modern and fossil representatives of rhinoceros.

Najczęstszymi wadami uzębienia u koni są wady zgryzu pod postacią ostrych krawędzi zębów policzkowych, co jest spowodowane nierównomiernym ścieraniem się ich powierzchni trącej (17). Do rzadko występujących zaburzeń stomatologicznych u koni należy zwiększona liczba zębów (hyperdontia, polidontia).…”

The aim of this report is to present a clinical case of an additional tooth (dens suplementarius) in a 13-year-old thoroughbred mare currently used for pleasure riding. She was referred for specific dental evaluation because of recurrent nasal discharge that started to change from mucous to mucopurulent. The first attempt to remove the additional tooth was performed on the standing horse, but was unsuccessful because of the location of the problem. Surgical procedures under general anaesthesia, that is, trepanation of the nasofrontal sinus and "sinus flap," succeeded. The mare was under antimicrobial therapy for 7 days after the surgery and received NSAID drugs for 2 more days. Medical dressing was removed 2 days after the surgery, and sinus flush with Foleys catheter was performed during 8 days after removing the dressing. The mare returned to previous work soon after the surgical procedure.Dental problems are among the most common in field veterinary practice, but supernumerary teeth occur in only a small percentage of horses. Cases of such tooth abnormalities are usually detected in the early or middle age of an animal during a regular dental examination or when the situation starts to create clinical problems. A suspicion of an additional tooth should always be confirmed by imaging diagnostics. In most cases, radiological evaluation is enough to confirm the diagnosis and asses the situation before selecting a specific medical solution.
