This retrospective clinical study was performed to determine the suitability and success rate of endodontic treatment of equine incisors presenting with apical and periapical disease.
All horses presented to a referral equine dental clinic between March 2013 and December 2019 specifically selected as candidates suitable for endodontic treatment were included in this study.
Initial clinical and radiographic presentation of incisor disorder cases suitable for endodontic treatment were recorded (88 incisors) and follow-up examination for long-term viability (8 months to 5 years) was performed in cases involving 32 incisors in total.
A total of 68 horses with 88 incisors were included in this study for endodontic restorative treatment. Different dental materials were used, with a temporary 3-layered technique using calcium hydroxide apically and temporary cement and resin composite occlusally most commonly used at the first treatment. Complete obturation with resin composite was performed in 48% of the cases requiring second treatments (50 incisors). Follow-up examination involving 32 incisors showed that successful endodontic treatment was achieved in 75% of the teeth treated.
Endodontic treatment of diseased incisors is a viable option in equid patients with a success rate comparable to humans in practice. The use of flowable resin composite as an obturation material has been shown to be successful at either the second treatment or in carefully selected patients at the first treatment.
To compare anamnestic factors in Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH) in affected and nonaffected horses to detect risk factors for horses developing EOTRH.
A total of 154 Icelandic horses, aged 15 years and older, examined at 22 locations in Lower Saxony, Germany. The investigations took place from October 2020 to December 2021.
Anamnestic data were collected using an owner-completed questionnaire. Horses underwent a thorough physical examination and CBC. The rostral oral cavity was clinically examined, and intraoral radiographs of the incisors were taken. Clinical and radiographic findings were scored. Based on the results, the study population was separated into “EOTRH-affected” and “EOTRH-healthy” horses. Both groups were compared to identify differences within the anamnestic factors. In case of inconclusive findings, some horses were classified as “suspicious”.
The diagnosis of EOTRH was made in 72.2% (109/151) of horses. The risk of contracting the disease increased with the age of the horse (P = .004). In addition, there was a predisposition for male animals (P = .032). Feeding, keeping, and dental treatments showed no significant influence, while place of birth seemed to influence horses developing EOTRH (P = .017).
The results highlight how widespread EOTRH is among the German Icelandic horse population and the need for raising awareness of EOTRH, as many horses were not suspected of having EOTRH beforehand. Moreover, numerous etiological propositions exist, but, to date, no studies have investigated their relevance.
Evaluate the short-term effects of acupuncture on the dynamic manifestations of axial stiffness in steeplechase racehorses.
12 steeplechase racehorses presenting signs of axial stiffness during training.
Horses were randomly assigned to either an acupuncture treatment by an experienced certified acupuncturist (n = 6) or no treatment as negative controls (6). The horses’ locomotion was evaluated during training before treatment (D0) and 7 (D7) and 14 (D14) days after by their rider and trainer through a questionnaire. Additionally, the improvement of their dorsal flexibility 2 days after treatment was evaluated subjectively at the trot, free jumping at the canter was evaluated by expert clinicians, and free jumping at the trot was evaluated objectively via inertial measurement units.
Significantly more horses were improved on D7 and D14 in the acupuncture group (6/6) compared with the control group (1/5; P =.01) according to the scores set by the trainer and riders. Subjective evaluation of the dorsal flexibility also revealed a significant improvement (P = .04) for horses receiving the acupuncture treatment (median improvement score, 0.50 [reference range, 0.5 to 0.9]) compared with control horses (–0.25 [reference range, –0.5 to 0]).
Acupuncture may be an interesting nondoping strategy to improve clinical signs of axial stiffness and performance on steeplechase racehorses.
