The vascular supply of the periodontal membrane.

摘要: The blood supply to the periodontal membrane of 84 human tooth sockets was studied by determining number and size perforations in alveolar wall. A special impression duplication technique used produce a relief This next drawn on paper stereo-microscope. By means measure-and-weigh method, calculations were made per unit surface area different regions each alveolus alveoli, sq. mm. After it had been demonstrated that, rat, correlation existed wall between both vessels that they carry, taken as measure membrane. The results, which all tested statistically, showed increases gradually from towards posterior sections dentition, this increase is similar jaws. individual greatest gingival least middle third. There are no significant differences four surfaces socket. The small with diameter less than 150 μ considerably greater large ones, latter most frequently located apical thirds alveolus. significance these findings discussed.
