title: [Observations on microvasculature of the periosteum of infant mandibular ramus by scanning electron microscope].
abstract: In this paper, a vascular casting method using methylmethacrylate was adopted. Satisfactory samples were obtained and electron microscope observations were carried out on periosteum microvasculature of infant mandibular ramus. There were significant differences in the density and arrangement of periosteal microvascular in various regions. In muscular attached region, the blood vessels showed a high density and bundle-like arrangement parallel with the direction of muscular fibers. In nonmuscular attached region, the blood vessels showed a marked low density and an irregular net-like arrangement. Between muscular bundles small arteries into periosteum were seen. Around the mandibular foramen the vessels of the periosteum formed a high density region. The clinical application of the above mentioned results were discussed.
