JOURNAL FREE ACCESSUntil now there have many reports on the use of a single instrument for the observation of complicated tongue movement. There have been a few, however, on the use of several instruments having common characteristics for the same purpose. Accordingly, we decided to carry out a fundamental experiment. Five males with individual normal occlusion and normal functioning and between the ages of 23 and 27 served as volunteer subjects. By utilizing X-ray T. V., real-time ultrasound (U. S.) and a strain-gauge pressure transducer in order to observe and measure tongue movement, we developed to synchronous measuring system. It measured the duration of tongue movement during swallowing through X-ray T. V. imaging, U. S. imaging and lingual pressure waves, and peak of lingual pressure. It examined the interrelationship of the duration between X-ray T. V. imaging, U. S. imaging and lingual pressures, and peak of lingual pressure.
The results were as follows.
1) The average values for the duration of lingual pressure shown by two strain-gauge pressure transducers were 1.84 (S. D.±0.47) sec., for tongue movement observed through X-ray T. V. imaging were 2.30 (S. D.±0.47) sec., and for tongue movement observed through U. S. imaging were 2.09 (S. D.±0.50) sec.
2) The coefficient for variation (C. V.) of values of total swallow duration increased in the order lingual pressures 25.5 (%), U. S. imaging 23.9 (%), and X-ray T. V. imaging 20.4 (%).
3) Duration of tongue movement showed conclusively a high relation between X-ray T. V. imaging and U. S. imaging (r=0.9661). Duration of lingual pressure showed conclusively a high relation to duration of tongue movement through X-ray T. V. imaging (r=0.9685).
4) The average value for the peak of lingual pressure shown by the two strain-gauge transducers was 172.1 (S. D.±42.5)gw/cm2.
The durations of lingual pressure (r=0.9387), tongue movement through X-ray T. V. imaging (r=0.9462) and tongue movement through U. S. imaging (r=0.9231) all showed a conclusively strong relationship to the values for the peak lingual pressure.View full abstractDownload PDF (5585K) -

JOURNAL FREE ACCESSWith recent advances in imaging technology, the needle biopsy under the guidance of CT has been developed. A case was presented, in, which this procedure was performed. A 68-year-old woman suffering from odontogenic infection showed swelling of a cervical lymph node on CT during the treatment. The node was considered to be malignant or reactive lymphadenopathy. The CT-guided fine-needle aspiration biopsy was performed, and the swelling was diagnosed as chronic lymphadenitis. As a result, the resolution therapy was strengthened, and the patient improved rapidly. Since this method was technically easy, safe, and beneficial to patients, oral radiologists were recommended to be experienced in this procedure.View full abstractDownload PDF (6151K) -

JOURNAL FREE ACCESSIn order to make a guideline for appropriate routine diagnostic imaging system for the tempor-omandibular joint (TMJ), a questionnaire was sent to every 29 Oral radiology section of dental college and university school of dentistry in Japan.
In this article, the opinions of the respondents were analyzed concerning the following items:
1) observable and limited structures in the TMJ by each imaging method
2) significance of the imaging methods
3) ideal routine diagnostic imaging system.View full abstractDownload PDF (1849K) -

JOURNAL FREE ACCESSIn order to make a guideline for efficient routine diagnostic imaging system for the temporoman-dibular joint (TMJ), a questionnaire was sent to every 29 oral radiology section of the dental colloge and university school of dentistry in Japan.
The part III dealt with radiographic terms for the osseous changes of the TMJ. The terms employed here were erosion, eburnation, sclerosis, marginal proliferation, osteophyte, deformity, loss of bone density, pseudocyst, concavity, flattening, facet, calcified body and loose body. The usage of those terms and the opinions about the relationship between those terms and the pathology by each respondents was analyzed.View full abstractDownload PDF (606K) -

JOURNAL FREE ACCESSWe analyzed the results of a questionnaire regarding the use of sialography forwarded to 28 departments of Dental Radiology at institutions located throughout Japan.
Responses were from 24 departments. Sialography was performed at 18 departments (75%), where it was used less than 40 times during the year 1988 in 80%, although there was wide variation among institutions in this frequency.
Two methods of cannulation were used.
At most institutions, Urograpfin 76%® was used, and at three institutions, Omnipaque 350 ® was used.
Sialography of the sublingual gland was performed at two departments, and secretory sialography at four.
It was found that the technique considered the most difficult was cannulation.
More than half of the respondents reported that they planned to use sialography in the future for information.View full abstractDownload PDF (2773K) -
