Abstract
The purpose was to investigate whether amlodipine, a second-generation calcium antagonist used for the treatment of hypertension and angina, interferes with healing of rat alveolar bone. A progressive increase in volume density of new bone filling the socket was quantified by a histometric differential point-counting method 7–42 days after tooth extraction. The results showed a 20–30% decrease in bone volume fraction in the alveolus of amlodipine-treated animals from 7 days on, in addition to a higher (7–35%) volume fraction of connective tissue and a tendency toward an increase in the volume fraction of persisting coagulum. If confirmed in humans, the knowledge of a deleterious effect of Ca-channel blockers in hindering alveolar bone healing would be important in planning oral operations involving bone tissue, including those for device implantation.
