Mandibular Torus with Tongue Movement Disorder: A Case Report

We report a case of movement disorder of the tongue caused by mandibular torus.The patient was a 73-year-old woman. In regards to intraoral findings, painless masses 20 x 15 mm in size that were well-defined, nodular, and of bonelike hardness were found bilaterally in the gingiva on the lingual side of the lower premolars. Tongue movement was limited, as the lingual frenulum was trapped in the area that had been narrowed by the bilateral masses, making it difficult to extend the tongue to its original position and therefore the masses were removed under general anesthesia. After surgery, the course of the patient was favorable, with no tongue movement disorder or other symptoms observed

Relationship between Oral Condition and Bone Density as shown by Results of Public Health Screening Examinations using Functional Tooth Evaluation Score

In our previous study, we examined the relationship between the results on bone density of the calcaneus measured by ultrasonography (echography) and the number of remaining teeth. However, it is difficult to conclude that the number of remaining teeth alone is sufficient for use as a parameter of the oral condition, though this parameter is indispensable for quantifying and expressing the oral condition as a numeric rating. In the present study, the bone density of the calcaneus was compared with the results of a similar parameter known as the Functional Tooth Evaluation Score (FTES), and the following findings were obtained: 1. Both FTES results and the number of remaining teeth demonstrated a positive correlation at the same level with bone density of the calcaneus, though the confidence level was higher for the FTES. 2. FTES reflected changes in the oral condition more closely than the number of remaining teeth. Thus the FTES is a practical parameter for judging long-term changes in the bone density of the calcaneus

Magnetic Resonance Imaging of the Normal Tongue: Qualitative Evaluation of Fat-suppressed Contrast Enhanced Images

Objective: For diagnosing the lesions on magnetic resonance imaging (MRI), it is necessary to understand normal structures on each sequence. In this study, we attempted to clarify structures of the normal tongue on fat -suppressed enhanced MRI qualitatively. Clinical material and method: Twenty-seven fat-suppressed enhanced MR images of normal tongue were studied, which were obtained using a T1 weighted spin echo pulse sequence (T1WI- E) with the chemical shift selective (CHESS) method by a superconducting MRI scanner operating at 1.5T. Tongue structures and their signal intensities on fat-suppressed enhanced images were assessed and compared to those obtained by non-enhanced T1WI. Results: Normal tongues were found to be composed of a symmetrical high signal area (HSA), low signal area (LSA), lingual septum, bilateral sublingual gland, and genioglossus muscle on non- enhanced T1WI. In the fat-suppressed enhanced images, HSA and lingual septum signal intensities were suppressed. Further, though the lingual mucosa was well visualized in fat-suppressed enhanced images (P<0.05), differentiation of HSA and LSA was difficult as compared to the non- enhanced scans (P<0.05). Conclusion: Fat-suppressed enhanced scans demonstrated simple anatomical structures as com- pared to conventional T1WI with independent signal intensity. Accordingly, we conclude that it is necessary to use both sequence for diagnosing the mass lesion located in the tongue

Relationship between Oral Condition and Bone Density Assessed from Results of Public Health Screening Examinations

Recently, relationships between diseases encountered in the fields of medicine and those in dentistry have been reported in the context of periodontal medicine. In the present study, we examined the relationship between the results on bone density of the calcaneus measured by ultrasonography (echography) and the number of remaining teeth, which studies were performed by local governmental authorities. The subjects were 235 women between 30-70 years of age whose bone density of the calcaneus was examined by echography. Our analysis indicated that subjects with 19 or fewer remaining teeth had an 11-fold greater risk of reduced bone density of the calcaneus, as compared with subjects with 20 or more remaining teeth. (Odds ratio: 10.9, 95% confidence interval: 3.18 for the lower limit, 37.37 for the upper limit). The bone density of the calcaneus in these former subjects was 79% or below the mean value for young adults. These results suggest a direct relationship between tooth loss and osteoporosis, and indicate that for a diagnosis of osteoporosis, an echographic examination would be more pertinent or needful for those women having 20 or more teeth remaining
