“…Dental wear disorders and other dental disorders were found widespread within the study population examined. Dental wear disorders were found in all age groups with a higher prevalence than in other abattoir population studies (Brigham and Duncanson, 2000b;Anthony et al, 2010).…”

Highlights• The prevalence of dental disorders in an abattoir population of horses was determined.• Findings during oral examination of intact and bisected heads were also compared.• Older horses had a higher prevalence of infundibular caries, diastemata and fractures.• Gasterophilus larvae were detected in 20% of the heads examined.• Oral examination of intact heads was adequate for diagnosing gross disorders. AbstractDental care is an integral part of equine veterinary practice. The objectives of this cross sectional study were to describe the prevalence of dental disorders in an abattoir population of horses, and to compare oral examination of intact and bisected heads. Heads from 40 horses were examined, 19 males and 21 females, divided into immature, adults and older horses. Older horses in this abattoir population had a significantly higher prevalence of infundibular caries (91.7%), diastemata (66.7%) and fractures (58.3%), whereas dental wear disorders affected all age groups.Gasterophilus larvae were detected in 20% of the horses. The oral examination performed on intact heads was adequate for diagnosing gross disorders, but further examination is needed for reliably diagnosing minor disorders.

“…However, the disease can be clinically difficult to diagnose and is seldom recognized by equine practitioners. 12 The sample of 16 skulls that were used in this study were obtained from donkeys in a larger post mortem study of 349 donkey skulls that had a very high CT diastemata prevalence of 85.1 %. 2,4,8 Diastemata have been observed in 4.6 % of 349 referred horses with cheek teeth dental disorders.…”

Dimensions of Diastemata and Associated Periodontal Food Pockets in Donkey Cheek Teeth

Equine cheek teeth (CT) diastemata often cause deep periodontal food pocketing and are therefore regarded as a painful dental disorder of equidae. However, there appears to be no information available on the size or shape of these diastemata. This post mortem study examined 16 donkey skulls (mean age = 32-years) containing 45 CT diastemata to define the anatomical shape and dimensions of these diastemata, and of the associated periodontal food pockets that occur with this disorder. Diastemata were found to more commonly involve mandibular (56.0 %) compared with maxillary CT (44.0 %), and 71.0 % of these diastemata had adjacent intercurrent dental disorders that may have predisposed donkeys to the diastemata. The median widths of all diastemata were 2.0-mm at the occlusal surface and 3.1-mm at the gingival margin, with no differences in widths between the lateral or medial aspects of diastemata. Diastemata were defined as open (60.0 %) or valve (40.0 %) based on their gross appearance. This classification was confirmed to be accurate by measurements that showed valve diastemata to have an occlusal to gingival width ratio of 0.4, in contrast to open diastemata where this ratio was 1.07. Food was impacted in 89.0 % of diastemata, but all diastemata had adjacent periodontal disease. Periodontal food pocketing was present adjacent to 76.0 % of diastemata, more commonly on the lateral aspect (73.0 % prevalence; mean pocket depth = 4.1-mm) than the medial aspect (47.0 % prevalence; mean pocket depth = 2.4-mm). The depth of periodontal pockets of diastemata was not associated with the height of the erupted crowns of adjacent CT.

“…Caries is characterized by destruction of the calcified dental tissue with bacterial fermentation action of the food debris hidden in cavities in the infundibulum of the affected check tooth . Although the most common type of dental carries identified in equine teeth is maxillary cheek teeth (CT) infundibularcemental caries with prevalence ranging from 13 to 100% in horses over 12 years of age (Colyer, 1906;Honma et al, 1962;Dixon et al, 2000;Brigham and Duncanson, 2000), high level of severe peripheral dental caries involving all classes of teeth (incisors, canines and CT) have also been found in horses (Dixon et al, 2011). Dental caries: dental caries had significant difference on colic in horses, since F (2, 3) = 13.000, p < 0.05.…”

Evaluation of dental abnormalities were carried out on a group of 74 polo horses with history of colic (colicky group) and another group of 70 randomly selected polo horses with no history of colic (noncolicky group) under similar environmental and management condition at Lagos Polo Club, Lagos, Nigeria in order to investigate probable correlation between dental abnormalities, routine dental care and predisposition to colic. Visual examination of the horses' oral/dental status was carried out after adequate physical and chemical restraint with intravenous administration of 2% xylazine hydrochloride at dose rate of 1.1 mg/kg body weight. Structured interview of handlers and review of dental health records where available were carried out to investigate routine dental care. One-way analysis of variance (ANOVA), Pearson correlation and linear multiple regression analysis were used to find out associations between dental abnormalities, routine dental care and colic. Thirty-eight (38) horses (51.4%) among the colicky group had dental abnormalities ranging from overjet (4.8%) to dental attrition (26.2%), while twenty-two (22) horses (29.7%) among the non-colicky group had dental abnormalities. Dental caries and sharp enamel point had significant difference (p < 0.05) on colic in horses and were positively correlated with colic. There were also positive significant correlation between fractured tooth and overjet (r = 0.908) and malposition and overjet (r = 0.944), respectively. Age and sex had no significant correlation with dental abnormalities and predisposition to colic, while local breeds were found to be more predisposed to colic due to dental abnormalities (p < 0.05). There was also a significant difference (p < 0.05) in horses that had no routine dental care and colic. In conclusion, this study indicates that dental caries and sharp enamel points are predisposing factors for colic in horses. Although not all forms of dental abnormalities predispose horses to colic, routine dental examination and care would be beneficial for early diagnosis and prevention of dental abnormalities that may predispose to colic.
