“…Listmann et al . found that the occlusal angle for both mandibular and maxillary cheek teeth (with supporting bones) varied between 15.1° and 20.2°. In this study, the hinge technique, as described by Carmalt, was used to measure the occlusal angle .…”

“…The occlusal angle of cheek teeth has been measured using different methods, which might account for the variety of reported angulations in the literature [23,25,26]. Carmalt [23] recorded an occlusal angle range in mandibular cheek teeth between 6.2 and 16.2°, whereas Brown et al [25] recorded a range of 19.2-30°in mandibular cheek teeth and 12.5-18.5°in maxillary teeth.…”

Equine cheek teeth show a high prevalence of occlusal fissures. Despite some evidence of predilection sites on the tooth surface that might indicate a mechanical aetiology for these lesions, no associations were found with wear abnormalities or occlusal angles of affected cheek teeth. Further histological and ultrastructural studies are warranted to elucidate their aetiology and possible role in other dental diseases.

The routine inspection of the equine oral cavity allows a numerical assessment of the teeth and provides information about positional changes within the dentition. By use of appropriate dental equipment, the occlusal surfaces of all teeth can be inspected and diagnosed. However, neither the teeth nor their occlusal surfaces are constant structures. Instead, equine teeth and, in particular, their occlusal surfaces are subjected to continuous morphological and positional changes due to the effects of aging and the equine-specific high amount of occlusal wear. Therefore, it is mandatory to define anatomical criteria, which allow us to distinguish between anatomical variations and pathological conditions. Moreover, an unambiguous nomenclature with regard to the equine-specific dental anatomy is essential. This article provides a tutorial overview of the equine dental anatomy as well as recent findings in the field of equine dentistry. Special attention is paid to dynamic changes within both individual teeth and dentition.

The evolution of mammals is characterized, amongst other developments, by an increasing relevance of effective food processing in form of an increasingly durable dentition, complex occlusal surfaces, and transverse chewing movements. Some factors have received increasing attention for the facilitation of the latter, such as the configuration of the jaw joint, the chewing muscle arrangement and lever arms, or the reduction of interlocking cusps on the cheek teeth occlusal surface. By contrast, the constraining effect of the anterior dentition (incisors and canines) on transverse chewing motions, though known, has received less comprehensive attention. Here, we give examples of this constraint in extant mammals and outline a variety of morphological solutions to this constraint, including a reduction of the anterior dentition, special arrangements of canines and incisors, the nesting of the mandibular cheek teeth within the maxillary ones, and the use of different jaw positions for different dental functions (cropping vs. grinding). We suggest that hypselodont anterior canines or incisors in some taxa might represent a compensatory mechanism for self-induced wear during a grinding chewing motion.We propose that the diversity in anterior dentition among mammalian herbivores, and the evolutionary trend towards a reduction of the anterior dentition in many taxa, indicates that the constraining effect of the anterior dentition, which is rigidly linked to the cheek teeth by the osseous jaws, represents a relevant selective pressure in mammalian evolution.
