ジャーナル フリーGenerally the radiological survey of cranio-facial regions has been conducted by routine radiography with superimposed images; yet there recently has developed a need for more accurate diagnostic information of particular layer depth, which found its answer in thin layer tomography with its image layer varying from 1.3mm to 1.8mm thick.
The bone-structure of cranio-facial regions, in contrast with corps and other extremities, is rather complex, which results in the variety of geometrical representability, as is often the case in thin layer tomograms. With routine radiography, this complex bone-structure can sometimes lead us into the danger of misdiagnosis because of the partial deterioration of clarity and contrast of images which consequently hinders geometrical represent-ability of the object.
With a view to amend this deficiency of thin layer tomograms, the present author investigated the possible adaptability of zonography, which has thicker tomographic zone than other tomography now in general use. He invented “Combination Zonography” by certain combination of tomographic angles, and conducted laboratory and clinical examination, confirming its distinguished contribution.
The results were as follows;
1. “Combination Zonography” is found advantageous in the blurring effect which is characteristic to any thin layer tomography, and yet at the same time it is found to have the advantage of excellent contour representability as thick layer tomography does.
2. “Combination Zonography” ameliorates the detectability of low-contrasted cysts in maxillary antrum and of positional relationship between these cysts and their surrounding tissue, with great contribution to the diagnosis of maxillary antrum diseases.抄録全体を表示PDF形式でダウンロード (11552K) -

ジャーナル フリーIn intraoral radiography, there is a marked difference in the exposure dose to various organs depending upon the site of examination. Therefore, when estimating the exposure dose of a population group, the frequency of exposure by site in that particular group must first be ascertaind.
As intraoral radiography is performed primarily for examination of diseases of the teeth and their surrounding hard tissues, the relationship between incidence of caries and periapical lesions and frequency of exposure by site can readily be estimated.
In the first report of this study, a review was made of the incidence of diseases observable on dental film by site based on full-mouth radiograms of 603 clinical dental in-terns of Osaka Dental University.抄録全体を表示PDF形式でダウンロード (548K) -

ジャーナル フリーA 15-year-old Japanese boy was referred on February 28, 1976, by his dentist to the Kyushu Dental College Hospital for treatment of a swelling on the left mandible and discharge of yellow pus.
There was a swelling on the mandible extending from the right mandibular canine to the left mandibular first molar. On examination, the swelling seemed to be parchment crepitation and slightly tender to pressure. Severe displacement of the teeth was also seen in the affected regions.
Radiographs revealed a 3×8cm. multilocular cystic lesion with a well-defined margin which extended from the right mandidular first molar to the left mandibular third molar.The left mandibular first premolar was within the lesion. On the basis of the radiographic findings, a provisional diagnosis of ameloblastoma was made, but the diagnoses of odontogenic myxoma and odontogenic keratocyst were also considered.
Histopathological diagnosis was odontogenic keratocyst.抄録全体を表示PDF形式でダウンロード (7374K) -

ジャーナル フリーIn cysts accompanying expansion of the walls of the maxillary sinus, there are mucocele, hydrocele, and pyocele. And mucoceles are called as mucoid retention cysts, mucoid retention phenomenon, and mucous cysts. Mucoceles in the maxillary sinus are found rare, although mucoceles of the frontal, ethmoid, and sphenoid sinuses are common.
And either non-secreting type or secreting type is seen in the mucosa of maxillary sinus.
The trauma of mixture gland ducts has been thought to be the etiology of mucocele, but recently it is thought that the etiology is rhynogenic or odontgeoic.
It is clinically believed that mucocele is symptomless in general, but it may be said that it in the condition of the expansion of the walls of the maxillary sinus accompanys with some symptoms.
This is report of a case considered as multiple mucocele which was accidentally found in the panoramic roentgenograms of the maxillary sinus.抄録全体を表示PDF形式でダウンロード (8100K) -

ジャーナル フリーA case of malignant giant cell tumor of the right side of the mandible in a 42-yearold man is presented.
Radiographic findings showed radiolucent area with ill-defined margins and suggested osteogenic tumor. At this stage a skeletal radiographic survey could not disclose other pathological findings.
Treatment with radiotherapy and chemotherapy was not effective, and surgical resections were applied, but the tumor rapidly recurred and affected into regions which involved right side of maxilla, opposite side of the whole mandible and infiltrated the soft tissue of the mouth.
Consecutive radiographic evaluation revealed progressive destruction of bone, recalcification pattern in the later stage of tumor, and definite evidence of metastatic involvement in the lung.
The patient died after the suffering time of three and a half years.抄録全体を表示PDF形式でダウンロード (8854K) -
