Figure 3.

bSEM of D14 Mandibular Molars. Day 14 is the day before the first molar erupts into the oral cavity and is often the last day that the developmental form of the molars can be observed prior to potential attrition from function. Lingual views are shown on the upper two panels, and occlusal views on the lower two panels. The crowns from all three genotypes are similar, but the homozygous Fam83h ^Tr/Tr molars display a rougher surface texture. Note in the occlusal views that the molar cusp tips are thin and pointed on all teeth, as they have not yet undergone occlusal wear
