Histopathologic and Electron-microscopic Studies of the Teeth Appeared in the Ovarian Cyst Wall

The teeth, taken from the ovarian cyst which appeared in left ovary of a 46-year-old woman, were studied histopathologically and scanning electron-microscopically. 1. The histological structure of the teeth resembled closely to that of a normal tooth, but a great deal of the hypocalcified portions in the enamel and dentin were found. 2. The surface of the hypocalcified enamel was slightly opaque with the naked eye, and mottled fossae were observed in the same area by scanning electron-microscope. The interglobular dentin was observed in the hypocalcified dentin. 3. In some dentinal tubles, peritubular matrices and closures of dentinal tubles were confirmed microradiographically and electron-microscopically

Clinico-pathological Studies on the Healing of Periapical Tissues due to Root Canal Filling with the Pastes of Calcium Hydroxide added Iodoform

Two root canal filling materials, consisted chiefly of calcium hydroxide and iodoform, "Calvital" and "Vitapex" were used to the teeth of a 78-year-old man and an 82-year-old woman respectively. One or two years later these teeth with alveolar bone were resected from the patients died, and observed histopathologically. 1. These human materials especially periapical tissues to which applied "Calvital" and "Vitapex" were thought to be the first cases examined histopathologically. 2. In 6 "Calvital" cases, 3 cases with enlargement and cleaning of the root canals before filling showed a good healing, and 1 case with the same treatment was nearly good, but 2 cases without this root canal treatment showed not so good. 3. The "Vitapex" case was only one, in which the root canal filling was carried out after the pulp extripation. The apical foramen was closed by an osteoid hard tissue, meaning a success healing. 4. In this "Vitapex" case, the patient was old and laid up with illness soon after the filling. Therefore this success healing may be suggested that "Vitapex" is excellent for root canal filling and that the cells in periodontal ligament of such an aged patient still have a capacity of differentiation to osteoblasts or.cementoblasts. 5. Clinically it may be noticed that in the radiograph the disappear of radiopaque materials in the root canal does not mean disappear of calcium hydroxide but of iodoform
