Supplemental or eumorphic are the terms used to refer to supernumerary teeth of normal size and shape, which may also be termed incisiform
Local accounts of excessive tooth breakage (all moose >7 years old had broken incisiform teeth) and enamel defects in a declining moose population on the Seward Peninsula, Alaska raise special concern (Smith 1992, Rozell 2003, Stimmelmayr et al.
Incidence of incisiform tooth breakage among moose from the Seward Peninsula, Alaska, USA.
4) in HL; teeth of jaws uniserial posteriorly, becoming biserial at front of jaws with addition of slender buttress teeth in spaces between main row of larger teeth; teeth incisiform
to conical in shape, about 36-38 in each jaw of holotype (excluding buttress teeth).
The pronghorn was probably >3 years old based on average length of his horns (34 cm; O'Gara, 2004a) and presence of eight large incisiform
teeth (O'Gara, 2004b).
It also differs from the incisiform
wear reported in Kenai Peninsula moose by Peterson et al.
We used incisor arcade width (the distance between the buccal surfaces of the incisiform canines, 14) as a proxy of body size for adult moose.
We assumed independence of contra-lateral teeth (Perzigian 1977) and therefore did not apply a Bonferroni correction for comparison of contra-lateral incisiform measurements.
Incisiform tooth wear and breakage in our population differs from the age-related tooth wear observed in other Alaskan moose populations (Stimmelmayr and Maier, unpublished data).
