Oral hairy leukoplakia occurs on the lateral surface of the tongue that clinically as an asymptomatic white lesion. It is mainly found in patient with human immunodeficiency virus infection. However, it rarely outbreak immunosuppressed patients after organ transplantation, or the patients taking steroids or immunosuppressants. It is the result of proliferating Epstein-Barr virus in the oral epithelium. Most of human immunodeficiency virus infected patients with oral hairy leukoplakia are highly contagious and possible to progress acquired immunodeficiency syndrome. Therefore, the early diagnosis of oral hairy leukoplakia is very important. Taking a thorough history and human immunodeficiency virus screening test is highly recommended in case oral hairy leukoplakia is detected. In this case, a 29-year-old man presented with whitish lesion on lateral border of tongue is diagnosed as oral hairy leukoplakia and human immunodeficiency virus infection.

In order to study the effects of the low power density laser (AsGa) on the wound healing of tongue and skin, thirty two healthy rats were anesthetized with pentothal. The tongue wound, approximately 1 mm in depth and 2mm in diameter, was created on the anterior of the tongue and the skin wound, approximately, 2mm in depth and 6-8mm in diameter, was created on the back of rat with the tip of small rongeur forcep. Wounds of experimental groups were irradiated with AsGa laser (Stomalaser, SEDATELEC Co., France) every other day by ninth day. The areas of wounds were measured at 1, 3, 5, 7, 9 days after wounding and the specimens were sectioned, stained, and observed with light microscope. The results were as follows : 1. In the AsGa laser irradiated wound of tongue, the epithelial and fibroblastic regeneration were accelerated when compared with controls. 2. In the AsGa laser irradiated wound of skin, the epithelial and fibroblastic regeneration were accelerated when compared with controls. 3. When the wound areas were compared, there was a significant difference between control group and experimental group (P < 0.01: 2-Way NOVA).

Hunminjeongeum was made by the Great King Sejong, and composed of 17 consonant and 11 vowel letters. All the 28 letters were made according to the shape of vocal organ or space at the point of articulation for each letters. This review article focused on phonetic and phoniatric consideration for explanation of the designs of the middle vowel letters, especially three main vowel letters [ • (天, heaven), ㅡ (地, earth), ㅣ (人, human)] using video-fluoroscopic evaluation as well as computed tomography scanning, etc. During articulating / • / sound, a ball-like space at frontal portion of the oral cavity was found, tongue was contracted, and sound was deep (舌縮而聲深). During /ㅡ/ sound, a flat air space between oral tongue and hard palate was created. Tongue was slightly contacted neither deep nor shallow (舌小縮而聲不深不淺). During /ㅣ/ sound, tongue was not contacted and Sound is light (舌不縮而聲淺). Tongue was moved forward making longitudinal oro-pharyngeal air space. So, I'd like to suggest that we had better change the explanation drawing from a philosophical modeling to a more scientific modeling from real vocal tract space modeling during articulating middle vowels of Hunminjeongeum.

Purpose: To measure the absorbed doses of cone beam computed tomography (CBCT), which is recently being more frequently used, and to compare them with those of panoramic radiography. Materials and Methods: To measure the absorbed doses of CBCT ($PSR-9000N^{TM}$, Asahi Roentgen Ind. Co., Japan), we placed TLD chips on the skin regions above the parotid and thyroid glands, and on the dorsum of tongue in a dental head phantom. We used two image acquisition modes of the Dental and Panoramic modes of CBCT, which differed in the field of view. Also, panoramic radiographs (Auto IIIN, Asahi Roentgen Ind. Co., Japan) were taken to compare with the absorbed doses of CBCT. Result: In the Dental mode of CBCT, the absorbed doses of the parotid gland, dorsum of tongue, and thyroid gland were 3.53, 3.13, and 0.36 mGy, respectively. In the Panoramic mode of CBCT, they were 9.57, 9.15, and 0.85 mGy, respectively. The panoramic mode showed higher absorbed doses than those of the Dental mode. In the panoramic radiography, the absorbed doses of the parotid gland, dorsum of tongue, and thyroid gland were 1.21, 1.19, and 0.16 mGy, respectively. And they were about 1/3 of the Dental mode and 1/9 of the Panoramic mode of CBCT. Conclusion: Absorbed doses of CBCT are higher than those of panoramic radiography, and dependent upon the field of view.

The author examined the clinical and histological changes on the dorsal tongue mucosa of adult Sprague-Dawley rats after lasing by pulsed Nd:YAG laser. The dorsal tongue was lased for 3 seconds by 1.5, 2.0, 2.5, 3.0, 3.5, 4.0W and 10, 15, 20, 20pps. After tissue changes were observed clinically, the excised samples were observed histologically and the width of tissue destruction was analyzed quantitatively under the Confocal laser microscope respectively. The following results were obtained : 1. Whitening of peripheral tissue was observed more as increasing pulsed per second (Hz) below power 2.5W and observed at all parameters above power 3.0W. 2. Charring of mucosal surface was observed at all parameters but mild at parameters below power 2.0W. 3. The destruction of epithelium was observed at all parameters and tissue destruction was extended to lamina propria at higher pulses per second. 4. The width of tissue destruction was more widening as increasing energies per pulse (p<0.001) and the narrowest at 20Hz than 10Hz, 15Hz and 30Hz(p<0.05). As the above results, author suggests power below-3.5W and 20Hz as the lasing parameters for oral soft tissue therapy.
