JOURNAL FREE ACCESSThe purpose of this study was to evaluate anxiety and depression in patients with temporomandibular disorders (TMD) who were treated at the First Department of Oral and Maxillofacial Surgery, Tokyo Medical and Dental University Hospital, Tokyo. The subjects were 41 males and 172 females with a mean age of 35.0 years (range: 13-70 years). Clinical evaluation was conducted using a Hospital Anxiety and Depression Scale (HAD). Anxiety and depression scores were compared between subjects and non-TMD patients. The two groups were mached for age and sex. The HAD results showed that TMD patients had significantly higher (P<0.001) anxiety scores and depression scores than non-TMD patients (based on the Mann-Whitney U test).
Then, the influence of 19 factors on anxiety or depression of TMD patients was assessed. The results of logistic regression analysis suggested that limitation in activities of daily living, lack of social support, neurotic personality traits and dizziness might be associated with anxiety in TMD patients, and neurotic personality traits, introverted personality traits and limitation in activities of daily living during the past 12 months might be associated with depression. In this study, personality traits were assessed using the Eysenk Personality Questionnaire (EPQ). TMD symptoms (joint and muscle pain, limited range of motion, and noise during movement), other physical symptoms (headaches, stiffness of shoulders and neck, arm and back pain, arm and back numbness), age, sex, and classification of TMD (mainly myogenous, combined myogenous and arthrogenous, and mainly arthrogenous) were not strongly associated with anxiety or depression in TMD patients.View full abstractDownload PDF (2211K) -

JOURNAL FREE ACCESSBackground and Purpose: Functional magnetic resonance imaging (MRI) has been utilized to design human brain mapping. However, the activated brain region of the gustation is not demonstrated by this method. The purpose of this study was to evaluate the possibility of manifestation of the activated brain area upon gustatory stimulation by functional MRI.
Subjects and Methods: Functional MRI upon gustatory stimulation was performed in five healthy volunteers using a clinical 1.5 Tesla MR scanner. Echo planar imaging with gradient echo sequence was used in all subjects. Subjects were stimulated by placing bitter tasting quinine acid on their tongues. The
stimulation paradigm consisted of the “off” periods of ten scans and “on” periods of ten scans.
Results: It was found that most activated areas were recognized in the insula and/or the operculum regions. The average rate of increased signal intensity due to activation was 5.8%.
Conclusion: The results of the activated brain regions almost agreed with those of previous studies done by other methods. It was suggested that brain function upon gustatory stimulation could be demonstrated on a clinical MR scanner with echo planar imaging of gradient echo sequence.View full abstractDownload PDF (2759K) -

JOURNAL FREE ACCESSA case of dilated odontoma was reported. The patient, a 37-year-old male, was referred to our clinic for evaluation of the left mandible. A transparent lesion l0mm in diameter was observed in the buccal region of left 3rd molar tooth of mandible in panoramic and dental X-ray films. Clinically, the lesion was diagnosed as odontoma and surgically extirpated under local anesthesia with extraction of 8. The extirpated material was mostly composed of hard tissue, and macroscopically various degrees of hard tissue was arranged in a circle. Histologically, the outer layer was composed of cementum with gradual transition to bone tissue, inside of which was dentin with dentinal tubules and enamel. The center of the material was filled with irregular calcified tissue like cementum. Small root formation was also found. These findings were compatible with those of dilated odontoma. This case was a rare example of supernumerary tooth of the mandible.View full abstractDownload PDF (3309K) -

JOURNAL FREE ACCESSThis report is about a case maintained by hemodialysis over a long-term with osseous changes in mandibular head assessed by several kinds of imaging in which relation with dialysis osteodystrophy was strongly suspecte.
The patient was 49-year-old male who had secondary hyperparathyroidism and dialysis-related amyloidosis in scaphoid bone and shoulder joints and visited our department with the complaints of bilateral temporomandibular joint pain and uncomfortable feeling upon mastication. He underwent hemodialysis treatment 24 years ago.
Radiographically, there were absorption and bone cystic radiolucency in the mandibular head.View full abstractDownload PDF (2757K) -

JOURNAL FREE ACCESSIn this study, psychosomatic evaluation was carried out using State-Trait Anxiety Inventory (STAI), which can simultaneously evaluate state anxiety and trait anxiety. From 1994 to 1997, 44 cases of oral tumors were treated at the Department of Oral and Maxillafacial Surgery, Aichi Medical University. These cases were divided into three groups: 20 patients with oral cancer in the first group were informed of their diagnosis; 12 cases with oral cancer in the second group were not informed; and 12 cases in the third group had benign oral tumors. All cases were analyzed by this scale both before and after treatment.
State anxiety after treatment decreased significantly compared to that before treatment in all three groups. The groups informed or not informed the cancer diagnosis tended to be more anxious than the group with the benign tumor. Stage III and N cases tended to be more anxious than stage I and II cases in the groups informed the cancer diagnosis. On the other hand, there was not significant difference among the groups in trait anxiety or preand posttreatment.View full abstractDownload PDF (780K) -

JOURNAL FREE ACCESSThe purpose of this study was to investigate an anatomical feature of the mandibular ramus from the viewpoint of oral surgery. Computed tomography (CT) of 100 patients with normal mandibular ramus (50 males and 50 females) were the subjects. At just the slice of mandibular foramen in the axial plane, the shape of the mandibular ramus, the width and the length of mandibular ramus and the distance to the mandibular foramen from the posterior/anterior edge were measured.
The results were as follows:
(1) The lateral border of mandibular foramen of one-fourth in males and one-third in females placed outside the line of interpostero-anterior edge.
(2) Mean of the angle between the sagittal plane and the posterio-anterior axis of the mandibular ramus was 11° in males and 8° in females.
(3) Twelve percent of males and 14 % of females had the mandibular foramen within 7 mm of the posterior edge of the ramus.View full abstractDownload PDF (2119K)
