The tongue has been globally considered as an indicator of general health for millennia. This study aimed to determine the prevalence and distribution of tongue lesions in an Iranian population. In this retrospective study, data from 6,435 oral biopsy reports over a 22-year period (1992-2014) were retrieved from archives of Oral and Maxillofacial Pathology Department, Shahid Beheshti Dental School, Tehran, Iran. These reports were analyzed according to age, sex, type of lesion and location. Prevalence of tongue lesions were reported as percentages. Out of total oral lesions, 238 (3.7%) were found in the tongue, with the incidence peak (42%) being between 41-60 years. Men constituted 53% and women 47%of patients. The youngest patient was a 3-year-old girl with pyogenic granuloma and the oldest one was a 93-year-old man with squamous cell carcinoma (SCC). SCC was the most common (25%) lesion generally found in the lateral border of the tongue with a male predilection. The second and third most prevalent lesions of the tongue were benign keratosis (frictional keratosis) (13.4%) and leukoplakia (13%).White-red lesions (38.6%) were the most frequent subgroup followed by neoplastic lesions (28%). Moreover, irritation fibroma, non-specific ulcers, squamous papilloma, and hemangioma were found as the most frequent lesions in their related subgroups.Given the high rate of SCC of the tongue in Iranian patients, this area should be examined more carefully by dental practitioners and physicians.

Recently, the occurrence and death rates of cancer have increased rapidly. In oriental medicine, the tongue gives some kind of special physiological information on human body. Oriental medical doctors have used information about the color, degree of wetness and shape of the patient's tongue to determine patient's disease and body condition. This fact leads us that the tongue image is one of the most important clinical data for helping doctor's decision making. It also has significant meaning to cancer patients related with traditional theory of oriental medicine. In diagnosis and treatment of cancer, tongue diagnosis can give some prognosis and change o cancer. It also detect the sign of early stage cancer, but it cannot diagnose the kind of cancer and/or benign or malignant. Nowadays BioTechnology(BT) has developed rapidly, but there are a lot of limits(economy, accuracy, clinical significance, etc). Tongue diagnosis is very economic and practical way of diagnose and has a lot of possibility of development. The need for doctors and it also helps the development of tongue diagnosis related with cancer.

Tongue posture at rest position of Class III malocclusion is very important in malocclusion and phonation. Because Class III malocclusion shoves low tongue position, speech defect is commonly occured. This study was attempted to evaluate the correlationship between the tongue posture at rest position and during /s/ phonation and facial skeleton in centric occlusion. Thirty subjects with Class III malocclusion who had no orofacial defects such as cleft palate, medical history of neurologic pathology, hearing defect and any previous speech therapy were selected. Ninety sheets of lateral cephalometric radiographs taken at rest position, during /s/ phonation and centric occlusion were traced, measured and statistically analysed. The results obtained were as follows ; 1. In Class III malocclusion, the posture of tongue was positively correlated with the position of hyoid body. The hyoid body was positioned anteriorly and inferiorly as the vertical facial skeleton was increased in centric occlusion. 2. In Class III malocclusion, the vertical position of tongue tip at rest position was not correlated with facial skeleton in centric occlusion, but the horizontal position had low correlation with mandibular body length, APDI, and $\underline{1}$ to SN. 3. In Class III malocclusion, there was the tendency that the dorsal position of the tongue was lowered as the vertical facial skeleton was increased. 4. In Class III malocclusion, the vertical and horizontal position of tongue tip during /s/ phonation was not correlated with facial skeleton in centric occlusion.

PURPOSE. Squamous cell carcinoma (SCC) of the tongue has a relatively high incidence of all oral cancers. Some studies have reported a relationship between intraoral dental prosthesis and SCC of the tongue; however, this relationship remains controversial. The purpose of this study was to investigate the relationship between SCC of the tongue and the positional aspects of dental prosthesis using a retrospective analysis. MATERIALS AND METHODS. A total of 439 patients with SCC of the tongue were diagnosed and treated in the Department of Oral and Maxillofacial Surgery, Seoul National University Dental Hospital. Patients were treated over a 12.5-year period ranging from January 1, 2001 to June 30, 2013. Statistical analysis was performed to examine potential differences between the groups. RESULTS. The number of patients with a crown and/or a bridge (134, 63.5%) was significantly different than the number of patients without a prosthesis (77, 36.5%). Even after accounting for different types of prostheses such as crowns, bridges, and dentures, no significant differences were observed between the position of the prosthesis and the location of the SCC of the tongue, with significance defined as a P-value less than .05 by the Pearson-Chi square test. CONCLUSION. Patients with crowns and/or bridges exhibited more frequent SCC of the tongue compared with patients without these prosthesis. These data support the hypothesis that mechanical trauma and galvanic phenomena play a role in the etiology of SCC of the tongue.

본 연구는 구강관리행태와의 연관성과 설태지수, 치석, 스케일링 전후의 구강환경에 따른 구취변화를 알아보고자 대전광역시에 위치한 K대학교 치위생학과에 스케일링 실습을 위해 내방한 참여자 130명을 대상으로 설태지수와 구취를 조사하여 조사하였다. 모든 조사대상자에 대하여 설문조사, 설태지수와 치면세균막과 치석정도를 측정한 구강검사, 구취측정 등을 하였다. 그 결과 설태가 구취에 가장 큰 영향을 준다는 것을 확인할 수 있었고, 이러한 설태지수는 흡연과 혀 닦기와 관련이 높았다. 또한 구취는 잇솔질 횟수가 많을수록 낮은 수치를 보였고 비외과적 치료인 스케일링을 통해 구취감소의 효과가 나타났으며, 나이와 설태지수가 관련요인임을 확인하였다. 이에 적절한 구강관리를 실천하여 치태과 설태의 양을 줄이고 정기적인 스케일링을 받음으로써 구강건강증진은 물론 구취감소의 효과를 얻어야 할 것이다.

Background: Tongue reconstruction is challenging with the unique function and anatomy. Goals for reconstruction differ depending on the extent of reconstruction. Thin and pliable flaps are useful for tongue tip reconstruction, for appearance and mobility. This study reports lateral arm free flap (LAFF) as a safe and optimal option for hemi-tongue reconstruction, especially for tongue tip after hemiglossectomy. Methods: Thirteen LAFFs were performed for hemi-tongue reconstruction after hemiglossectomy from 1995 to 2018. Of the 13 patients, seven were male and six were female, age varying from 24 to 64 years. Results: All flaps healed uneventfully without complications. Donor sites were closed primarily. The recipient vessels for microvascular anastomosis were mainly superior thyroidal artery, external jugular vein. All patients returned to normal diet, with no complaints regarding reconstructed tongue and donor site. Conclusion: The LAFF is hairless, thin (especially with lateral epicondyle approach), and potentially sensate. They are advantageous features for tongue tip and hemi-tongue reconstruction. Donor site sacrifices the inessential posterior radial collateral artery, and the scar is hidden under short sleeve shirts. We believe that LAFF can be considered as the first choice flap for hemitongue reconstruction, over radial forearm free flaps.

The IEEE 1451 publication are available, this standard defines interface between sensor and processor, and plug and play in processor is possible. Also, Intelligence of sensor was possible because sensor includes transducer electronic data sheet (TEDS). In IEEE 1451 standards, IEEE 1451.4 is suitable standard in single sensor, and IEEE 1451.2 is suitable standard in multi-sensors (array sensor). In this paper, apply IEEE 1451 to electronic tongue system. In the case of electronic tongue system, because array sensor is used, it is that complex and difficult to apply IEEE 1451.4 that is standard for single sensor. In this paper, apply IEEE 1451.2 for array sensor to design of electronic tongue system. Communication interface method of IEEE 1451.2 for electronic tongue system is presented, and implemented TEDS of electronic tongue system.

This study was designed to examine relations between posture and size of the tongue and dentoalveolar pattern. The sample was consisted of three groups, the 34 subjects of Normal occlusion, the 31 subjects of Bimaxillary protrusion and the 31 subjects of Class III malocclusion. On the cephalograms, lengths, heights and areas of the tongue and intermaxillary space and on the study model, arch length, intercanine width, intermolar width and palatal height were measured. These data from measuring cephalograms and models were statistically analyzed. The results of the study were as follows; 1. Length of the tongue was the greatest in Bimaxillary protrusion and in order of Normal occlusion and Class III malocclusion. 2. Posture of the tongue was the lowest in Class III malocclusion and in order of Bimaxillary protrusion and Normal occlusion. 3. There were a tendency to be larger area of tongue and intermaxillary space in Class III malocclusion compared to Normal occlusion and Bimaxillary protrusion. 4. Size of the tongue and intermaxillary space showed low correlations with the dentoalveolar pattern.

Oronasal fistulae (ONF) could remain after surgery in some patients with cleft palate. ONF ultimately requires intraoral surgery, which may lead to perioperative airway obstruction. Tongue flap surgery is a technique used to repair ONF. During the second surgery for performing tongue flap division, the flap transplanted from the tongue dorsum to the palate of the patient acts as an obstacle to airway management, which poses a great challenge for anesthesiologists. In particular, anesthesiologists may face difficulty in airway evaluation and patient cooperation during general anesthesia for tongue flap division surgery in pediatric patients. The authors report a case of airway management using a flexible fiberoptic bronchoscope during general anesthesia for tongue flap division surgery in a 6-year-old child.
