Hereditary hemorrhagic telangiectasia is a rare autosomal dorminant disease that features abnormal and fragile vascular dilations of terminal vessels in skin and mucous membranes, as well as arteriovenous malformations of internal organs, particularly lungs, brain, and liver. Often patients have not been diagnosed with HHT for a long time, and undiagnosed HHT patients unnecessarily develop serious complications such as severe life-threatening hemorrhage, stroke or brain abscess. Therefore, early detection and appropriate screening is very important. Early detection of HHT allows the appropriate screening for the presence of silent disease such as AVMs in the lungs, liver, or brain, and preventive treatment in the patient and their affected family members. Dentists should be familiar with HHT because the telangiectases on skin and oral mucosa are often the most dramatic and most easily identified component of HHT. Recently, we experienced a case of HHT. We present the case with a review of the literature.

Children commonly experience orofacial injuries and often need emergency treatment. Due to fear and anxiety, children tend to be uncooperative in emergency rooms. Ketamine hydrochloride is a well-known sedative agent at medical-based emergency rooms which has been used for procedural sedation. In this paper, we will discuss the sedation of uncooperative young patients, who needed dental treatments in the emergency room at Wonju Severance Christian Hospital, using ketamine. We collected the records of patients under 18-years-old who visited the emergency room for dental treatment from January 2010 to May 2014. The data was categorized by age, sex, required dental treatments and application of ketamine sedation. Among 659 pediatric patients who visited for emergency dental treatments, 118 patients were treated under sedation using ketamine. Majority of patients were under the age of 6 (110 patients), and the most frequent cause of sedation was suture of oral laceration (105 patients). Though ketamine should not be used by dentists alone, dentists in emergency rooms can easily meet the patients under deep sedation using ketamine. Hence, dentists in emergency rooms need to be aware of the clinical effects, considerations, and potential adverse effects of ketamine.

Passive fit of prosthesis is an essential property of implant supported prosthesis for long term success and minimization of complications. And the property is determined mostly by fabrication procedure. There were limitations of extensive implant prosthesis because conventional casting method generate contraction error of long span prosthesis. However, Computer-aided design/Computer-aided manufacturing (CAD/CAM) technology of 3D printing and milling metal framework can overcome those limitations. This case is a full mouth rehabilitation using extensive implant fixed prosthesis. Removable interim prosthesis was made for esthetic, functional evaluation and a guide for implant insertion. After the insertion, implant fixed interim prosthesis was delivered. After additional evaluation and adjustment, final prosthesis was designed with CAD, the fabricated with CAM. Milling technique was used for anterior screw type implant superstructure and 3D printing technique was used for the anterior and posterior implant copings. Fit of the final restoration was favorable. The practitioner and patient were both esthetically and functionally satisfied with the final result.

Often there are edentulous patients with severe vertical resorption of the alveolar ridge so that implant placement in the mandibular posterior is impossible. In this case, implants can be placed in the anterior portion of the mandible and the patient can be treated with an implant assisted overdenture, but the inherent discomfort of the removable prosthesis can not be overcome. However, if implants are appropriately placed between the mental foramen of both sides and a fixed hybrid prosthesis is fabricated to the patient, the patient will be satisfied without the inconvenience of the removable prosthesis. However, the treatment plan should be well designed to prevent disadvantages and expected complications of fixed hybrid prosthesis. Based on my clinical experience, I will explain treatment plan and protocol in detail.

The evaluation of malocclusion has to be done quantitatively and qualitatively. This will be lead toward an analysis of malocclusion severity as well as treatment difficulty. The method of proper evaluation of malocclusion severity and treatment difficulty is necessary to assess treatment effect and efficiency for the orthodontists and to establish fundamentals for planning and executing the health-related policies in private and public institutions. The purposes of this study as the first part of the objective and quantitative analysis of malocclusion were 1) to measure treatment difficulty based on the opinions of several orthodontists. and 2) to investigate the relationships between objective malocclusion severity and subjective treatment difficulty 100 pairs of dental casts that had various types and severity of malocclusion were selected from the orthodontic departments of Kyurghee University and Samsung Medical Center The objective malocclusion severity was measured with the PAR (Peer Assessment Rating) index and the subjective treatment difficulty was evaluated by 8 experienced orthodontists. The relationships between objective malocclusion severity and subjective treatment difficulty were statistically evaluated. There were significant relationships between objective malocclusion severity and subjective treatment difficulty especially in the measurements of the upper anterior alignment, the buccal occlusion. the overjet, the overbite and the midline discrepancy en the malocclusion components. The results of this study can provide the background knowledge to develop a new occlusal index. which contains both the malocclusion severity and treatment difficulty for Korean orthodontists.

Dentally disabled person means one who have difficulty in cooperating voluntarily with a dentist for routine dental care. Seoul National University Dental Hospital (SNUDH) Dental Clinic for Disabled has worked for them under outpatient anesthesia concept. The aim of this study was to determine the anesthetic characteristics of the patients attending for dental treatment at SNUDH Dental Clinic for Disabled in order to establish better future treatment plans. The data were drawn from the patients who visited SNUDH Dental Clinic for Disabled from January 1999 to October 2002. Total 93 dental treatments for 83 patients were enrolled in this study. Most patients had mental retardation and the conservative treatments were carried out under general anesthesia. Thiopental and vecuronium were mostly used for induction agent and neuromuscular blocker, respectively. Enflurane, with oxygen and nitrous oxide, was mostly used to maintain the anesthesia. Mean total anesthetic time was $164.4{\pm}57.2$ minutes and mean duration at the post-anesthetic care unit was $106.2{\pm}50.5$ min. Serious postoperative complications were not observed. These results showed our successful anesthetic outcomes without any severe side effect or complication and the needs of more outpatient centers for dental care for disabled.

Wolf-Hirschhorn syndrome(WHS) is a congenital disorder caused by deletions of the short arm of chromosome 4. The most common characteristics are mental and growth retardation, dietary disorder and craniofacial features with a characteristic 'Greek warrior helmet' appearance. The dental characteristic of WHS includes delayed development, tooth agenesis, clefts, microdontia, taurodontism, and severely worn dentition. The purpose of this case report is to describe the dental treatment of a patient with WHS. 3-year-old boy with WHS visited the Seoul National University Dental Hospital for dental treatment. He had difficulty with nasotracheal intubation because of craniofacial anomalies and also had poor oral hygiene due to a limitation of mouth opening and dietary disorder. Due to his airway problem, behavior management and severity of dental conditions, dental treatment was performed under general anesthesia. This case suggests general anesthesia can be chosen with WolfHirschhorn syndrome patients to safely care for their dental problems.

Abutment teeth supporting removable partial denture could be faced a number of problems including development of dental caries. If the existing removable partial denture is in clinically acceptable state and the patient does not want to replace the existing removable partial denture, then a new prosthesis for abutment teeth need to be made. The procedure of fabricating a new prosthesis of abutment teeth for existing removable partial denture is complicate and technically challenging. To fabricate the abutment crown, the original cast of patient obtained before any complication to the abutment teeth is required. The original cast should also contain teeth other than the abutment teeth as a reference point. Once the cast is prepared, CAD/CAM could be used to produce retrofitting prosthesis effortlessly and efficiently. This clinical report presents fabricating a crown to fit existing removable partial denture using CAD/CAM for a patient with post and core failure and dislodged prosthesis. The prosthesis had high stability with minimum adjustment yielding satisfying result.

With the progress of medical treatment techniques of bleeding control, dental care of the patient with hemophilia has become more convenient. So many surgical treatments can be performed with out-patient. 2 cases of intraoral surgical treatment of children, one with hemophilia 3, sever, the other with hemophilia A, severe. While the former was treated under general anesthesia, the latter was treated under local anaesthesia. There are principles : 1. When a patient with hemophilia need dental treatment, the dentist must consult to his physician, pediatrician, or hematologist before dental treatment. 2. When the dentist make a treatment plan, there should be consideration of the general condition, cooperation of the patient and risk of the treatment needed. 3. Minimize the number of times of coming for dental treatment so that reduce the times that need replacement therapy of coagulation factor. And during the treatment, dentist should care for infection and bleeding.

Mandibular fracture is less common in children than in adults. However, children are more susceptible to ankylosis and developmental disorders, and don't respond as well to intermaxillary fixation compared to adults. On the other hand, bone fracture is healed more quickly in children and complications are scarce. Mandibular fracture in children is usually treated successfully with acrylic splint therapy with or without the use of eyelet wires and intermaxillary fixation. Severe complications that include ankylosis and developmental disorders may occur. The frequency and severity of such complications can be mitigated with a shorter duration of intermaxillary fixation and good post-operative care. Encouraging mandibular physical therapy by increasing patient motivation may be necessary in such cases where the patient's response is poor and the duration of intermaxillary fixation increases; when the patient is unable to undergo physical therapy, or when intermaxillary fixation is not necessary with the patient showing only minor symptoms such as trismus. In this case report, a 6 year-old girl with bilateral condylar fracture was treated with elastic in both the upper and lower jaws to allow mandibular physical therapy using a Benoist's appliance, which allows opening, lateral, and protrusive retrusive movements of the mandible. A 7-month follow-up showed beneficial therapeutic effects such as increased mandibular movement and prevention of condylar ankylosis.
