The indication for submandibular intubation is the requirement for intraoperative maxillomandibular fixation (MMF) in the presence of injuries that preclude nasotracheal intubation. Thus, We reported 2 cased of endotracheal intubations via submandibular approach that is applicable in patients with skull base fractures for a reliable general anesthesia. Endotracheal intubation via submandibular approach was applied during general anesthetic procedures for open reduction in three patients with Le Fort II, III or nasoorbitoethmoid (NOE) fractures. No complications due to submandibular intubation, such as infection, postoperative scarring, nerve injury, hematoma, bleeding, or orocutaneous fistula, were observed following submandibular intubation. Endotracheal intubation via submandibular approach is effective in patients with skull base fractures. In our method, the tube connector is removed in orotracheal intubation in order to avoiding the tube removal or displacement. The advantages of this method are very simple, safe, and to provide the good operation field.

General anesthesia may influence the postoperative sleep cycle; however, no clinical studies have fully evaluated whether anesthesia causes sleep disturbances during the postoperative period. In this scoping review, we explored the changes in postoperative sleep cycles during surgical procedures or dental treatment under general anesthesia. We compared and evaluated the influence of general anesthesia on sleep cycles and sleep disturbances during the postoperative period in adult and pediatric patients undergoing surgery and/or dental treatment. Literature was retrieved by searching eight public databases. Randomized clinical trials, observational studies, observational case-control studies, and cohort studies were included. Primary outcomes included the incidence of sleep, circadian cycle alterations, and/or sleep disturbances. The search strategy yielded six studies after duplicates were removed. Finally, six clinical trials with 1,044 patients were included. In conclusion, general anesthesia may cause sleep disturbances based on alterations in sleep or the circadian cycle in the postoperative period in patients scheduled for elective surgery.

Purpose: Many metal ions released from dental casting alloys have been reported to influence the intraoral symptoms of oral lichen planus (OLP) and burning mouth syndrome (BMS). The aim of this study was to investigate the relationship between salivary metal ion levels and the prosthetic duration as well as to evaluate the time-dependent morbid effects of metal ions in OLP and BMS patients. Methods: Three study groups consist of the following subjects respectively: 17 OLP patients, 12 BMS patients, and 12 patients without oral symptoms. The salivary concentrations of 13 metal ions (copper, cobalt, zinc, chromium, nickel, aluminum, silver, iron, titanium [Ti], platinum, tin, palladium, and gold) were measured by Laser Ablation Microprobe Inductively coupled Plasma Mass Spectrometry. Results: The Ti ions had statistically significant differences among the groups with a prosthetic duration of less than 5 years. There were no significant differences between all ion levels among the groups wearing dental cast alloys for over 5 years. In the BMS group, the level of Ti ions in patients with prosthetic restorations less than 5 years old were significantly high (p<0.05). Conclusions: In the BMS group, 3-60 months during which salivary Ti levels were higher were matched with the duration of burning symptoms ($15.6{\pm}17.1months$). Furthermore, Ti ions were statistically high in the oral cavity of BMS patients fitted with dental casting alloys for 5 years. These results suggest that Ti ions released from dental implants and oral prostheses could attribute to burning sensation of BMS.

Objectives : The purpose of this study was to analyze the dental fear of dental patients during treatment. Methods : Statistical package PASW 18.0 WIN(USA) was used to analyzed the frequency and percentage of the general characteristics. T-test and one-way ANOVA were used. Results : Females tended to have more fear than male. The first visit to dental clinic was the most important fear factor. Most of the subjects did not receive regular dental checkup because of fear since entering elementary schools. Conclusions : In order to reduce dental fear, comfortable environments may be necessary for treatment.

The aim of this study was to determine the condition of supportive periodontal therapy (SPT) in implant patients and the effect of SPT on implant long-term survival. Implants placed at the Dept. of Periodontology, Chonnam National University Dental Hospital over a 5-year period, were traced for up to 8 years. Patients who had visited the hospital at least once a year were defined as regular SPT, and patients who were treated by active periodontal therapy were defined as patients with periodontitis. Kaplan-Meier survival analysis was performed based on the observation periods, and the effect of SPT and history of periodontitis on implant survival assessed by chisquare test. A total of 183 patients (age: 21-91, 98 males and 85 females), and 508 implants were used for this study. Three hundred eight implants were under SPT and 87 implants was under regular SPT. For the patients with periodontitis 136 implants were placed. The 5-year survival rate was 94.8%. The overall survival rate in patients who received SPT was 97.1% and 91.0% for those who did not (p=0.004). The survival rate in patients who received regular SPT was 97.7%, and 96.8% for patients received irregular SPT. The survival rate was 93.4% in patients with periodontitis and 95.2% in patients without periodontitis. Among patients with periodontitis, the survival rate was 100.0% in patients who received regular SPT and 89.2% for irregular SPT (p=0.012). These results suggest that regular SPT improves implant survival rate and is more effective in patients with periodontitis.

Factor XI deficiency (Hemophilia C) is a very rare autosomal recessive bleeding disorder. Patients with factor XI deficiency do not typically show any spontaneous bleeding or specific symptoms. Sometimes those who have this disorder are identified during special situations such as trauma or surgery. Orthognathic surgery is particularly associated with a high bleeding risk. Therefore, great care must be taken when treating patients with bleeding disorders such as factor XI deficiency. There are a few reports that address the management of patients with bleeding disorders during orthognathic surgery. The current report describes a patient with factor XI deficiency who underwent Le Fort I osteotomy together with bilateral sagittal split osteotomy. The patient's condition was assessed using both rotation thromboelastometry ($ROTEM^{TM}$) and noninvasive measurements of total hemoglobin (SpHb) using Masimo Radical 7 (Masimo Co. CA, USA).

Dental treatment under general anesthesia is considered a good way for behavioral control in disabled patients. General anesthesia for disabled patients sometimes requires difficult airway management. In this case, intra-oral camera is great helpful to intubation. Originally, the intra-oral camera is designed to facilitate diagnosis dental disease. The intra-oral camera is very efficient on intubation. Laryngeal photo taken by Intra-oral camera can be good guide for difficult intubation. In this report, an 11-year-old boy with chromosomal anomaly received dental care under general anesthesia. And he had a potentially difficult airway. We achieved nasotracheal intubation successfully with intra-oral camera.

Airway obstruction in pediatric patients always poses a challenge for anesthesiologists. Beckwith-Wiedemann syndrome causes various abnormalities such as macroglossia and omphalocele. Patients with these abnormalities often need corrective surgeries. Management of difficult airway caused by conditions such as macroglossia in patients with this syndrome could be challenging. We encountered a case of difficult airway in an infant with Beckwith-Wiedemann syndrome. It was predicted that macroglossia might cause difficult ventilation, intubation, and extubation. Preoperative assessment and preparations for difficult airway should be considered.

Wolf-Hirschhorn syndrome is a rare hereditary disease that results from a 4p chromosome deletion. Patients with this syndrome are characterized by craniofacial dysgenesis, seizures, growth delay, intellectual disability, and congenital heart disease. Although several cases have been reported, very little information is available on anesthetic management for patients with Wolf-Hirschhorn syndrome. We encountered a case requiring anesthetic management for a 2-year-old girl with Wolf-Hirschhorn syndrome. The selection of an appropriately sized tracheal tube and maintaining intraoperatively stable hemodynamics might be critical problems for anesthetic management. In patients with short stature, the tracheal tube size may differ from what may be predicted based on age. The appropriate size ( internal diameter ) of tracheal tubes for children has been investigated. Congenital heart disease is frequently associated with Wolf-Hirschhorn syndrome. Depending on the degree and type of heart disease, careful monitoring of hemodynamics is important.

일부 지역 치위생(학)과 3, 4학년 학생 196명을 대상으로 장애인의 전반적인 인식, 장애인 치과학에 대한 교육 여부, 장애인 환자 구강관리 역량 자가평가를 자기기입식 설문지를 이용하여 조사하였다. 그 결과, 대상자의 대부분이 장애인이나 장애인 환자에 대한 긍정적인 인식을 가지고 있었으며 84.7%는 장애인 전문 치과위생사 양성이 필요하고 76.5%는 졸업 후에 장애인 치과진료 관련 세미나에 참가할 의향이 있다고 하였다. 그러나, 전체 대상자의 각 장애인별 업무역량에 대한 자가평가는 보통 수준 미만으로 장애인 치과치료에 대한 업무역량이 충분하지 않다고 생각하고 있었다. 대상자의 71.4%는 교과 및 비교과 교육과정에서 장애인 치과진료를 경험하였으며 경험을 한 대상자가 장애인 환자에 대한 지식, 구강보건교육, 구강병 예방처치, 진료보조, 의사소통의 대부분 영역에서 본인의 역량을 유의한 수준으로 높게 평가하였다. 이론교육이 충분하였다고 응답한 군에서도 충분하지 않았다고 응답한 군에 비해 장애인 환자 관리 역량에 대해 유의하게 높은 수준으로 자가평가를 하였다. 이를 토대로 보았을 때 현재 교육과정상 치위생(학)과 학생들의 장애인 치과치료에 대한 업무역량은 부족한 것으로 보이나 장애인 환자의 구강건강 관리 및 치과진료 보조에 대해 긍정적이며 장애인 환자에 대한 경험과 이론 교육 등이 효과를 나타낸다고 판단된다. 따라서, 교육과정에 장애인 치과학이 포함될 수 있도록 제도적 뒷받침이 필요하고 충분한 이론교육과 실습교육을 병행하여 장애인 환자의 구강건강 향상에 이바지할 수 있는 인력을 양성하도록 해야 한다. 또한, 현장 임상실습 교육 시 장애인 환자를 경험할 수 있는 여건을 마련하고 장애인 전문 치과위생사 양성에 대한 심도 있는 논의도 이루어져야 할 것이다.
