– The effect of an extreme and prolonged calcium‐depriving regimen on the degree of mineralization of alveolar bone, dentin and enamel in adult female rats has been studied by quantitative microradiography. This method is considered to be the method of choice for disclosing differences in V % hydroxyapatite (HA). Despite the calcium‐depriving regimen causing a substantial loss of bone mineral from femur and tibia, as estimated by gravimetric methods, the mineral content of alveolar bone, expressed as V % HA, did not deviate significantly from the normal, indicating that no osteolytic processes had taken place. Neither did the degree of mineralization of the fully formed molar dentin deviate from the normal. However, dentin and enamel formed during the experimental period by the continuously growing incisors disclosed a degree of mineralization which was significantly lower than normal. It was further noticed that the mineral content of the lingual dentin of the incisors, from both experimental and control animals, was significantly lower than the labial dentin.
