“…In the current study the mean age (12 years) of the whole population and horses with PC was older than the PC-affected horses (mean 8.1 years) in a previous study in which it was proposed that high levels of concentrates and haylage were risk factors for PC [3]. In contrast, infundibular caries can only affect the maxillary cheek teeth and most evidence would suggest the primary problem to be defects in cemental filling of certain cheek teeth, especially the Triadan 09s [17][18][19][20][21]. Peripheral caries preferentially affects the caudal upper and lower cheek teeth indicating an environmental change in the caudal oral cavity that favours the growth of cariogenic bacteria.…”

“…The cheek teeth infundibula extend almost the entire length of the crown (clinical and reserve crown) and thus can reach a length of up to 100 mm in young teeth (Fitzgibbon et al . ). The incisor infundibula are considerably shorter extending for only 10–30 mm into the dental crown (von Mueller 1908; Dixon and Du Toit ; Wissdorf et al .…”

A sound knowledge of dental and periodontal anatomy provides the basis for an accurate diagnosis of dental abnormalities. It must be remembered that dental and periodontal anatomy, especially in the horse, undergoes continuous morphological changes throughout life. From birth to age about 6 years the deciduous and later the permanent teeth emerge in turn through the oral mucosa. Even the permanent dentition is subjected to continuous, dynamic, morphological changes due to massive occlusal wear and the compensatory tooth eruption that is necessary in herbivores. Consequently, it is not surprising that the normal equine oral anatomy of structures shows a wide range of variations. The purpose of this tutorial article is to review and summarise the current knowledge of equine dental and periodontal anatomy, paying special attention to age related morphological changes.

Summary Computed tomography (CT) uses x‐ray beams and reconstructive computer technology to create tomographic slices (sections) of the area being imaged. Computed tomography has higher contrast resolution than conventional radiography allowing for more accurate differentiation of soft tissues and fluids. This form of 3D imaging removes problems caused by superimposition of multiple anatomical structures, which is a major impediment when viewing radiographs of the equine head. Once the images are acquired, multi‐planar and 3D reconstructions can be performed to view different teeth or associated structures in an optimal way. Anatomical and pathological changes in the dental tissues, periodontal tissues, alveolar bone and adjacent sinuses can then be assessed. Scintigraphy with 99m technetium methyl‐diphosphate (methylene‐diphosphonate) can detect changes in bone that precede radiographic changes, and this makes it a very useful imaging modality for diagnosis of early periapical infection of the equine cheek teeth. Additionally, it is invaluable for imaging suspected infections of supernumerary or dysplastic teeth where the results of radiography or even CT may be equivocal. Periapical infections of the cheek teeth typically result in focal and intense increased radionuclide uptake located over the apical region of the affected tooth.
