craniofacial
• x-ray analysis reveals dental attrition of the molar cusps at 3 months
• mandibular molars show a flattened enamel layer in 3-month old animals
• flattened enamel layer suggests that the molar enamel has a mineralization defect resulting in increased attrition with age
• a >2-fold decrease in molar-mineralized enamel volume is observed at 1 and 2 months compared to controls
• hypomineralized enamel can not be clearly separated from bone and dentin
• molar outer aprismatic enamel shows irregular organization with increased porosity
• enamel crystallites are thin and prismatic showing disorganization
• in mutants ameloblast morphology appears normal in teeth
• enamel is thinner along molar cusps in 3-month old animals
• enamel mineralization defect results in increased attrition with age
