Ectomesenchymal chondromyxoid tumor is a rare benign tumor. It occurs uniquely on the oral cavity particularly the tongue. It was first described in 1995, and only 36 cases were reported in the literature. We report a case of ectomesenchymal chondromyxoid tumor in a 67-years-old male, who presented with an asymptomatic, firm, round shaped mass on the dorsum of the tongue. The lesion was completely excised and confirmed as ectomesenchymal chondromyxoid tumor on histopathological examination.

Macroglossia is a rare clinical condition defined as an enlarged tongue. Macroglossia can cause structural deformities like diastema and disproportionate mandibular growth and present functional disorders such as dysarthria, dysphonia, and respiratory problems. A 7-year-old boy who had lymphangiomatous macroglossia was treated with a reduction glossectomy by anchor-shaped combination of a U-shape and modified key-hole resection. Postoperatively, the reduced tongue was contained completely within the oral cavity, but open bite remained due to prognathism. Sensory and motor nerves to the tongue appeared to be intact, and circulation was adequate. This patient will be monitored for recurrence of tongue enlargement.

흡지벽, 수직적인 골격 발육부전 등 여러 원인을 갖는 개방교합은 치아와 치조돌기에 국한되어 있는 단순 개방교합, 수직골격 발육부전에 의한 골격성 개방교합인 복잡 개방교합으로 나눌 수 있다. 단순 개방교합은 흡지벽, 농설벽 등 국소적 원인에 의하며 치조돌기의 수직적 발육결여와 상하악 잔치의 맹출 장애 등의 특징을 보인다. 농설벽은 혀가 상하악 전치 사이에 위치하고 혀의 주변부위가 구치부 교합면 사이에 놓이지 못하게 됨으로써 구치부 과맹출에 의한 전치부의 개방교합과 상악전치의 전돌을 가속화하게 된다. 악습관에 의한 개방교합을 가진 어린이에서는 습관을 없애주는 것이 개방교합을 치료하는 가장 좋은 방법일 것이다. 그리고 Hawley type 장치에 crib을 첨가하거나 oral screen을 장착시켜 농설벽을 치료할 수 있다 그리고 근기능요법은 동기유발과 혀의 기능을 조절하고 입술운동을 통해 새로운 연하운동을 발전시키도록 훈련하여 부정교합을 교정하거나 개방교합의 재발을 방지한다. 본 증례는 농설벽에 의한 개방교합을 가진 8세 여자 환자에서 탄성고무, 빨대를 이용한 연하연습과 발음연습을 포함한 근 기능요법과 습관제거장치를 이용해 습관의 중지 및 개방교합의 개선을 얻었기에 보고하는 바이다.

This study was to find dental materials causing hypersensitivity reactions by carrying out patch tests in the patients with oral mucosal lesions to investigate the possibility of hypersensitivity reactions in etiology of oral mucosal lesions. 31 patients (female 26, male 5, age range 24-72 years) with oral mucosal lesions were classified as patient group, and 41 volunteers (female 24, male 17, age range 23-40 years) without oral mucosal lesion, systemic disease and history of allergy as control group. The obtained results were as follows: 1. There were various dental restorations in most of patient group and control group, 29(94%) in 31 patient group, 35(85%) in 41 control group. 2. Among sites of oral mucosal lesions, buccal mucosa was the most common site with 60%, followed by gingiva with 24%, tongue with 16%. Lesions in contact with restorations were highly 90% in tongue and 89% in buccal mucosa, but comparatively lower 53% in gingiva. 3. The ratio of positive reactions to the patch test in patient group was significantly higher than the control group (p<0.05). 4. Dental materials causing positive reactions to the patch test were mainly mercury(19%), potassium dichromate(16%), cobalt chloride(16%) in patient group, cobalt chloride(17%) in control group. 5. In 20 patients with lichen planus, 8 patients(40%) showed positive reactions to the patch test.

Objectives: The aim of this research was to determine intra-oral factors that affect halitosis in young women. Methods: This study was performed between March 2014 to May 2014, and included 35 women in their 20s with good oral health. Correlation and logistic regression analyses were performed to investigate the change in halitosis immediately, and 1 hour after scaling. Results: In both oral gas (OG) and extraoral gas (EG) groups, halitosis was reduced after scaling compared to before scaling. The logistic regression analysis of oral state factors in OG showed that as oral fluid [odds ratio (OR) = 0.792, p = 0.045] and dental plaque (OR = 0.940, p = 0.016) decreased by 1 unit, the OR in the OG group decreased (> 50). In addition, as glucose levels in the oral cavity (OR = 1.245, p = 0.075) and tongue coating index (OR = 2.912, p = 0.064) increased by 1 unit, the OR in the OG group increased (> 50). Furthermore, in the EG group, as oral fluid (OR = 0.66, p = 0.01) and dental plaque (OR = 0.95, p = 0.04) decreased, the OR in the EG group decreased (> 50) significantly. Conclusion: To control halitosis, it is necessary to increase oral fluid and decrease the amount of tongue plaque. Furthermore, maintaining a healthy oral environment, aided by regular scaling and removal of dental plaque, may significantly control halitosis.

Objectives: The purpose of this study was to investigate the relationship between oral health factors and suicidal ideation in adolescents in order to provide basic data for adolescent suicide prevention and oral health promotion. Methods: This study used data from the Korea Youth Risk Behavior Web-Based Survey held in 2017, in which a total of 62,276 youth participated. Data were analyzed by SPSS Ver. 22.0. Complex logistic regression analysis was used to analyze oral health factors related to suicidal ideation. Results: The effects of oral health on male students' suicidal ideation were as follows: brushing teeth 2-3 times a day was associated with decreased suicidal ideation (p<0.01), while suicidal ideation was increased in individuals who had experienced scaling within the past year (p<0.001), or, among experiences of oral disease within the last year, had reported prickling and throbbing pain (p<0.001), pain on the tongue and inside the cheeks (p<0.001), or bad breath (p<0.001). The effects of oral health on female students' suicidal ideation were as follows: brushing teeth 2-3 times a day was associated with decreased suicidal ideation (p<0.001), while suicidal ideation was increased in individuals who, among experiences of oral disease within the last year, had reported pain when chewing (p<0.001), pain on the tongue and inside the cheeks (p<0.01), or bad breath (p<0.001). Conclusions: The above results demonstrate that adolescent suicidal ideation and oral health factors are correlated, and it will be necessary to incorporate oral health interventions when planning or developing projects and programs for suicide prevention in adolescents.

Purpose: This study observed the changes in the telomerase activity, it's developmental regulation, PCNA expression, and their correlation in rat's upper digestive organs during growth and aging. Materials and Methods: Upper digestive organs(buccal mucosa, gingiva, palate, submandibular and parotid glands, and tongue) were aseptically removed from Sprague-Dawley rats of fetal(gestational 20 days), growing(1, 2, 3, 5, and 7 weeks after birth) and adult(12 week old). Samples for telomerase activity were frozen on liquid nitrogen immediately after sacrifice, and stored until the use at $-75^{\circ}C$ in order to measure it. Telomerase activity was measured by a PCR-based telomeric repeat amplication protoco(TRAP) assay and quantitated with Photometric Telo TAGGG Telomerase PCR ELISA plus(Roche Diagnostics GmbH. Mannheim. Germany). PCNA expression were measured immunohistochemistry with anti PCNA Ab-1, Clone PC10(NeoMark. California. USA). Results: 1. Telomerase activities in buccal mucosa, palate and gingiva were the highest in fetus and decreased gradually or rapidly after birth and then diminished, but In salivary gland and tongue were the highest in fetus and also high at 1 week and then decreased rapidly. 2. PCNA expression in buccal mucosa, gingiva, Tongue and salivary gland was the highest in fetus and decreased gradually and then diminished. but only in palate decreased rapidly after birth and then diminished. Conclusion: The highest telomerase activity of embryonic stage decreased rapidly after birth in rat's upper digestive organs. There may be a developmental regulation of telomerase activity, but not a tissue-specific. This telomerase activity seems correlated closely with PCNA expression in rat's upper digestive system.

Objectives : Halitosis is a common human condition, exact pathophysiological mechanisms of which are unclear. This study, which investigates halitosis patients' characteristics and their related factors, was done with intent to establish a foundation for the Oriental Medical treatment of halitosis. Methods : 329 patients were surveyed by reviewing medical charts and questionnaires from the East-West Halitosis Clinic of Kyunghee Medical Center from May 1, 2001 to December 31, 2002. Sex, age, illness duration, coating on the tongue, postnasal drip, globus pharyngeus, indigestion, condition of feces, halimeter measurements and results of the salivary scans were analyzed. Results : The thick and yellowish coating on the tongue was not a major cause of halitosis in the patients studied. Among the halitosis patients, 21.6% complained of postnasal drip, 15.6% of globus pharyngeus, 37.4% of indigestion, and 23.8% of diarrhea or constipation, suggesting the possibility of extra-oral origin in oral malodor. Conclusions : This study suggests that, when treating halitosis patients, intra-oral causes of halitosis aside, Oriental Medical treatments such as solving qi-stasis(氣鬱), augmenting deficiency of the spleen qi(碑氣虛) and treating gastric fever(胃熱) constitute effective management for oral malodor patients.
