When curing the composite restorations with light curing units, the light guides are often in direct contact with oral tissues, therefore contamination of light guides is inevitable. Curing light guides fall into the "semicritical" instrument category according to the Centers for Disease Control and Prevention (CDC) and must be heat or vapor-sterilized or at a minimum, these semicritical instruments must be sterilized in a liquid chemical agent. Currently, most common methods of maintaining sterility of the light guides are wiping the guide with a disinfectant, such as glutaraldehyde, after each patient use; using autoclavable guides; using presterilized, single-use plastic guides; and using translucent disposable barriers to cover the guide.

Lichen planus is a common, chronic inflammatory disease of the skin and mucous membrane for which no precise causes have been confirmed. But it is often connected with infections. Helicobacter pylori(H. pylori) among various bacteria has been associated with the cause of gastritis, peptic ulcer and gastric cancer. Considering the similarities of histological features between gastric ulcer and oral ulcers, it is resonable to assume that H. pylori might also be involved in the development oral mucosal ulceration. So we employed this study to investigate the possible involvement of H. pylori in the aetiology of erosive oral lichen planus. We analyzed detection rate of H. pylori in saliva of patients with erosive oral lichen planus by nested PCR. As a result, it revealed a significant difference statistically by showing positivity in 16 to 21(76.2%) saliva samples of patients group and in 11 of 44(25%) saliva samples of control group(P>0.001). We were able to suppose that H. pylori in saliva can be related to cause of erosive oral lichen planus.

Burning mouth syndrome (BMS) is defined as the xerostomia, burning sensation and various discomfort of tongue and oral mucosa. BMS can occur in both men and women, but is more frequent in middle-aged menopausal women. Because exact cause can't be identified clearly and it is hard to make diagnosis in clinic, the purpose of the treatment have been to relieve symptoms. Etiology of BMS is divided into local, systemic, and psychological factors. ${\alpha}$-lipoic acid, clonazepam, supplemental therapy and cognitive behavior therapy can be prescribed for BMS. Nowdays, many experts focus attention on effect of combination therapy. It is necessary to solve the symptoms of the patients by combination of pharmacological approach and psychotherapy with cognitive behavior therapy considering the factors in various aspects.

흔히 여러 가지 형태로 나타나는 구강점막의 염증을 한데 일컬어서 구내염이라고 부르고 있다. 그러나 실지로는 이들 구내염의 원인이 많고 또한 복잡하며 때로는 원인을 잘 모르는 것이 있는가 하면 서로 다른 원인에 의해서 생긴 구내염도 구강 내에 들어온 여러 가지 세균에 의해서 이차적 감염을 일으켰을 때에는 같은 형태나 증상을 나타내는 경우가 있으며 바이러스나 진균에 의해서 또는 전신질환의 분증으로서도 발생되기 때문에 이들을 일률적으로 분류해서 이야기 하기는 어려우나 대체로 임상적인 면에서 다음과 같이 나누어 설명할 수가 있다.

Purpose. The objective of this study was to evaluate the behavioral response and assess the effectiveness of additional intranasal (IN) and submucosal (SM) administration of midazolam during pediatric sedation for dental procedure. Material and methods. Thirty-three cases of healthy (ASAⅠ), uncooperative children aged from 24 to 72 month old at pediatric dental clinic of Ewha Womans University Hospital were selected for this study. Children received oral chloral hydrate 50 mg/kg with hydroxyzine 1.0 mg/kg. After waiting for 45 minutes, midazolam 0.2 mg/kg was administrated via IN route and via SM route randomly maintaining 50% of $N_2O$. A pulse oximeter and a capnograph were used for measuring vital signs ($SpO_2$, PR, RR, $EtCO_2$) throughout the sedation. Behavioral response was evaluated as Quiet (Q), Crying (C), Movement (M) or Struggling (S) in every 2 minutes for 40 minutes. Results. There were also no statistically significant differences in vital signs of the two groups. The behavioral response for the first ten minutes during sedation was a statistically significant difference (P < 0.05) between the two groups. After the first ten minutes, it was revealed that there was no significant difference. Conclusion. This study demonstrated that the addition of IN midazolam to the combination of oral chloral hydrate with hydroxyzine and nitrous oxide/oxygen inhalation is as safe and effective as that of SM midazolam in pediatric sedation for dental procedure.

본 연구는 치과에 내원한 환자를 대상으로 치아우식증과 치주질환을 제외한 실제 구강건강도에 미치는 요인과 그 비중을 알아봄으로써 개인의 예방줌심 계속구강건강관리제를 운영하는데 기초자료로 이용하고자 한다. 2010년 7월 1일 부터 2010년 7월 30일까지 한 달간 유아기, 아동기, 청소년기, 청년기, 장년기, 노년기를 구분하여 각 연령별 40명씩 조사하여 6단계 연령층으로 총 240명을 대상으로 구강검사와 설문조사를 실시하였다. 연구결과, 치과 내원 환자들은 연령이 적을수록 구강건강도가 높음을 알 수 있다. 전신질환이 없을수록, PHP가 높을수록, 설태가 없을수록, 구강보조용품을 적게 사용할수록, 음주/흡연을 하지 않을수록 TMJ가 높을수록, 구강감염/점막질환이 없을수록, 저작능력이 높을수록 구강건강도가 높음을 알 수 있다.

The aim of this study was to investigate the oral health problems among type 2 diabetes patients and suggest basic data for the promotion of their body and oral health by emphasizing the correlation between hemoglobin A1c and subjective oral health status. For 174 patients with type 2 diabetes and who were older than 40 years old, the questionnaire and measurement of hemoglobin A1c were conducted from January 9, 2012 to March 9, 2012. The results of the study were as follows. 1. They tended to be most aware of the following; 'inflammation on the oral mucosa' and 'pain on the oral mucosa' among the symptoms of oral mucosa, 'gum bleeding when brushing teeth' among the symptoms of periodontal disease, and 'feels dry in general' among the symptoms of xerostomia. 2. The patients with longer duration of diabetes showed greater recognition with regards to the symptoms of oral mucosa disease, periodontal disease, and xerostomia (p<0.05). 3. The group with regular meal showed lower level of hemoglobin A1c (p<0.001). 4. The level of hemoglobin A1c was higher in the group that recognized 'burning sensation', 'gum bleeding', 'gum recession' and 'bad breath' (p<0.05) as well as in the group that responded 'get up at night to drink' among the symptoms of xerostomia (p<0.05). Especially the symptoms of periodontal disease were revealed to be a factor that showed the 3rd strongest correlation with hemoglobin A1c.

Recurrent aphthous stomatitis is common oral disease in the world. It is characterized by multiple, recurrent, painful ulcer with circumscribed margins, erythematous haloes and yellow or grey floors. Patients with recurrent aphthous stomatitis suffer from its painful ulcer. But unfortunately, its etiology and pathogenesis is not clear and still unknown. So we review etiology and pathogenesis of recurrent aphthous ulcer and wish to propose direction of the future study.

Epidermoid cysts are rare benign lesions in the oral cavity that may be either congenital or acquired. The cysts are usually slow-growing and asymptomatic until becoming secondarily infected or large enough to interfere with mastication and speech. Consequently, diagnosis is often delayed. The condition is also uncommon in newborns and infants. Most of the lesions occur in the floor of the mouth and rarely in the upper lip. This report describes the case of a 29-month-old girl with a palpable mass in the inner mucosa of the upper lip. The lesion was surgically enucleated using an intraoral approach and histopathologically diagnosed as epidermoid cyst.
