Summary:

Cephalometric studies are important to quantify abnormalities of jaw length and positioning. In this study, 4 to 7-month-old Quarter horse foals (n = 51) were examined to determine overjet (horizontal overlap) prevalence and measure the size of the physiological diastemata. Results were analyzed in relation to age, sex, and lineage. Another aim of this study was to develop a simple field technique for measuring incisor malocclusion and physiological diastemata dimensions that could be used to monitor the growth of the rostral components of maxilla, incisive bone, and mandible. The overall prevalence of overjet lesions in these foals was 51%. Females were overrepresented (61.5%). Overjet occurred more commonly in show foals (50% prevalence) than other working (7.7%) and race (42.3%) lineage foals. Significant differences were found between maxillary and mandibular physiological diastemata lengths in foals of all ages and,...

Dental disorders are common in horses, that is why the objective of this study is  to determine the frequency of dental problems in Chilean Rodeo Horses and describe the most common dental treatments used in Chile. Oral examinations were performed on 456 Chilean horses and the disorders were observed as follows...

Dentistry procedures for horses can be performed using power tools.  The use of power tools by persons without appropriate training introduces risk of harm to horses.  The paper argues that where the power tools are used, those procedures should be restricted to performance by veterinarians with appropriate training.  Despite this risk, some Australian jurisdictions have lifted the practice restriction or have legislated to allow lay persons (non-veterinarians) to use power tools.  This paper reviews the legislation in New South Wales, Queensland and ACT.  It traces the risks and arguments and concludes that the practice restriction is necessary.
