구강과 구인두에서 발생되는 유표피암은 전체 예수병원 암환자의 3.9%를 차지한다. 만 20 년 간의 월발성 유표피암 환자 5%명에 대한 고찰결과, 혀 전방 2/3 에서 29%로써 가장 높은 발생빈도를 보였으며 faucial arch, base of tongue 및 tonsil을 포함한 구 인두는 28%의 발생빈도를 나타냈다. 그외는 잇몸, 구강저, 구순, 구개 (palate) 및 구강내 점막의 빈도순이었다. 환자 중 153 명 만이 근치적 치료를 받았다. 1974 년 이전에는 치료 정책에 수술만이 활용되었던 까닭으로 역행성 분석결과 74 명에서는 수술만 시행케 되었으나, 그 이후의 70 명에서는 종합적치료를 시행하였으며 그중 9 명은 확실한 방사선요법을 받았다. COMMANDO 수술과 복합절제술 (Composite resection) 을 시행했던 환자들의 비교검토는 매우 의의가 있었다. 수술만 받은 환자와 비교해 볼때, 수술후 방사선요법을 병행했던 수술환자의 경우에 있어서 재발율은, Stage III 에서는 50%에서 41%로, Stage IV 는 79%에서 68%로 각각 감소를 보였다. 또한, COMMANDO 수술 경우만 국한시켜 비교할 때는 수술만 받은 환자와 비교할 때 수술후 방사선치료를 받은 환자와 비교하여 2 년간 무병율 (disease free interval) 이 수술후 방사선요법을 병행함으로써 17.3%에서 29.3%로 증가됨을 알 수 있었다.

The most common cause of mouth breathing is obstacles caused by mechanical factors in upper airway. Mouth breathing could be consequently pathological cause of sleep-disordered breathing. Sleep-disordered breathing in children can cause growth disorders and behavioral disorders. The purpose of this study was to investigate relationship between upper airway and sleep-disordered breathing in children with mouth breathing. Twenty boys between 7 - 9 years old who reported to have mouth breathing in questionnaire were evaluated with clinical examination, questionnaires, lateral cephalometric radiographs, and portable sleep testing. This study assessed apnea-hypopnea index (AHI) and oxygen desaturation index (ODI) for the evaluation of sleep-disordered breathing and was done to investigate the correlation between these values and the upper airway width measured by lateral cephalometric radiographs. There was no significant correlation with the size of the tonsils (p = 0.921), but the adenoid hypertrophy was higher in the abnormal group than in the normal group (p = 0.008). In the classification according to AHI and ODI, retropalatal and retroglossal distance showed a statistically significant decrease in the abnormal group compared to the normal group (p = 0.002, p = 0.001). As AHI and ODI increased, upper airway width tended to be narrower. This indicates that mouth breathing could affect the upper airway, which is related to sleep quality.

The deformities of micrognathia and glossoptosis in the newborn are frequently associated with a cleft palate, which is known as Pierre Robin sequence. Upper airway obstruction is the most serious problem in these patients. Treatment of Pierre Robin sequence includes either positional or surgical intervention. Mild cases are often managed in the prone position. However, when the patient fails to thrive due to chronic upper airway obstruction, or severe respiratory distress ensures despite positional treatment, surgical intervention is mandatory to relieve the obstruction. We experienced three infants with Pierre Robin sequence who showed a symptom triad of micrognathia, glossoptosis, and cleft palate. Intermittent cyanosis, depression of the chest, respiratory difficulty and feeding problems were also observed. To relieve severe upper airway obstruction caused by micrognathia and glossoptosis, we simultaneously performed modified tongue lip adhesion (TLA) and a subperiosteal release of the floor of the mouth (SRFM). Respiratory and feeding difficulties were relieved, the tongue positioned anteriorly, body weight increased, and mandibular growth improved. Simultaneous TLA and SRFM may constitute a simple and reliable method for surgical treatment of airway obstruction in patients with Pierre Robin sequence.

The purpose of this study was to examine the effect of LLLT on current perception threshold in trigeminal neuralgia patients. Affected site and non-affected site was irradiated by GaAlAs diode laser. Current perception threshold was evaluated with $Neurometer^{(R)}$ CPT/C before and after LLLT. As an outcomes,CPT were obtained. We made a comparision of these values and the results were as follows. 1. There were no significant difference in CPT between affected site and non-affected site before and after LLLT irradiation. 2. There were no significant difference in CPT between affected site and non-affected site after LLLT irradiation. 3. But, CPT values of $A{\beta}$ fiber incresed slightly on both site after LLLT irradiation

Russell-Silver syndrome is a type of intrauterine growth retardation, characterized by short stature noted at birth, hemiatrophy or asymmetry, variation in sexual development and other abnormalities, including cafe-aulait pigmentation and clinodactyly. Facial features commonly associated with this syndrome are a small triangular face, decreased facial height, down-turned corners of the mouth(shark's mouth), a small mandible, and occasionally asymmetry. The major intra-oral features of the syndrome that have been reported are a high-arched palate, delayed tooth eruption, microdontia, hypodontia, and crowding. These cases were diagnosed at birth as Russell-Silver syndrome by clinical features such as prenatal growth retardation, short stature, low body weight, et al., and have been treated with growth hormone. The purpose of this paper is to report the dental findings of two patients and review the pertinent literature through the two cases.

Multimodal cancer therapy including surgery, chemotherapy, and radiotherapy could not only improve the prognosis of malignancy but also reduce the dosage and toxicity of cancer drug for treatment of malignant tumor. The effects of radiotherapy are generally localized, additive, and accumulative, and depend on dosage, site and cell sensitivity. However, in growing individuals, the dental and skeletal sequelae to radiotherapy result in dental or facial abnormalities that are irreversible : arrested root development, disturbances in enamel formation, microdontia, anodontia, altered tooth eruption and mandibular or maxillary hypoplasia. Especially, the teeth which are developing is affected according to the stage. We report three cases of developmental disturbance of permanent teeth after radiotherapy. These children had received radiotherapy for malignant tumor at the age of 3 to 4 years, in which root hypoplasia, short tapered root and early apex closure were observed. For the management of radiation caries and radiotherapy-related teeth, periodic recall check and oral hygiene instruction are required.

The purpose of this study is to analyze the association of oral health of the elderly and oral health quality of life. The subjects of this study were 282 participants who received the fluoride application and the scaling service through program targeting elderly people carried out by a public health center located in Gyeongsangbuk-do Province. Data were collected from January 2011 to December 2011. The result of comparing subscale scores of quality of life related to oral health depending on socioeconomic characteristics showed that functional limitation scores were lower as educational level got higher. The result of comparing subscale scores of quality of life related to oral health depending on status of oral health and frequency of tooth brushing showed that quality in functional limitations, physical pain, psychological discomfort, physical disability, psychological disability, social disability and handicap scores were lower as the number of cavities got more. The result of multiple regression analysis to identify the factors affecting the quality of life related to oral health showed that the number of cavities and installation of denture were significant variables. The results of this study showed that there was significant association of oral health status and oral health related quality of life of the elderly. In order to maintain the oral health related quality of life, it is important to keep many number of residual teeth even if a person gets older and to support the installation of dentures if necessary.

In 2011, South Korea's Ministry of Health and Welfare started a national tooth brushing room program without a pilot project. This study aimed to assess the effect of the implementation of this program in Gangneung, Korea. One-year outcomes of oral health behavior and self-reported oral symptoms in the study group after installation of the tooth brushing room were evaluated and compared with those of the control group using chi-square test. The prevalence rate of good self-rated oral health in grade 1-3 students increased from 35.7% immediately after installation to 48.9% after 6 months (p=0.031) compared to 37.3% in the control group (p=0.051). Immediately after installation of the tooth brushing room, 53.5% of grade 1-3 students in the study group brushed their teeth every day, but after 6 months, only 35.5% of students brushed daily (p<0.001) compared to 28.6% in the control group (p=0.007). The prevalence rate of bad breath in grade 1-3 students was 26.2% for the study group immediately after installation compared to 25.5% in the control group (p=0.065), but it declined 16.5% after 6 months (p=0.055). The prevalence rate of bad breath in grade 4~6 students was 14.7% for the study group after 6 months compared to 25.3% in the control group (p=0.016). We recommend the creation of a healthy school environment through a school-based tooth brushing program under the active supervision of classroom teachers and the continuous monitoring of program processes in order to promote children's oral health.
