Foreign body indigestion during dental procedures is uncommon but sometimes associated with severe and life threatening morbidity. The dentist should decide whether multidisciplinary intervention is necessary and how urgently it has to be done. The active removal of foreign bodies depends on the size, shape, type and duration of impaction, along with the location in the gastrointestinal tract. In this report, we presented how to manage gastric foreign body related swallowing during dental procedure and investigated the predictive risk factors, precaution, and prompt management in foreign body ingestion.

As a dentist, we should be prepared for emergencies that can occur at any time in dental practice. In addition, we must be able to provide first aid to patients with the latest knowledge when an emergency actually occurs. It has been revised every five years since the American Heart Association published advanced cardiovascular life support (ACLS) guidelines. The current final guideline is the 2015 version. It is expected that the 2020 version will be released around the winter of 2020. Therefore, at this point, the latest version (2015 ver.) will be important. Many changes were made from 1995 to 2015. I would like to summarize the parts of the revised parts that remain important.

Objectives : The aim of this study is to investigate dental clinic fear and anxiety in high school students. Methods : The subjects were 311 high school students aged 19 years. They completed self-reported questionnaire including general characteristics, dental clinic experiences, dentist or dental hygienist confidence, and dental fear. Data were analyzed using SPSS 18.0. Results : Poor oral health status showed negative attitude towards dental clinic visit. Girl students tended to have more fear than boy students. Muscle tension was the most common experience and was closely related to anesthetic needles and drills. Dental anxiety was caused by lack of confidence to dentists and dental hygienists. Students were more afraid of dentists than dental hygienists. Higher score of dental anxiety seemed to be associated with infrequent visit to dental clinic. Conclusions : Frequent regular dental checkup may reduce dental fear and anxiety. Dental clinic staff should try to minimize dental anxiety in performing treatment.

A surgical operation on a patient with infected left atrial myxoma is presented. The patient was a 50-year-old woman who was admitted to the Kyung Hee Medical Center Hospital on March 7 1987 with complaints of high fever, cough and dyspnea that occurred a few days prior to admission. She, who no definite history of the previous cardiac-related problems was obtained from, had visited a dentist to have her eight teeth pulled out a few months prior to this admission. A preoperative 2-D echocardiogram revealed a left atrial tumor, strongly suggesting myxoma and two blood cultures drawn prior to surgery yielded streptococcus viridans. Under the preoperative impression of an infected left atrial myxoma, the tumor was removed through a biatrial approach after establishing CPB and cold cardioplegic. Pathologic examination of the tumor demonstrated a typical myxoma with bacterial colonies within. Postoperative course was uneventful and she was completely well at discharge from the hospital. To our best knowledge, this report is the first surgical experience of infected left atrial myxoma in the Korean literature.

Currently increasing use of implants, especially in anterior implant esthetics has become a major concern for both the patient and dentist. In the case of thin biotype if the thickness of the gingival soft tissue is less than 2mm, human eye can detect differences of colors depends on underlying materials. The zirconia abutment can be use not only for better esthetics but also for the hygienic because it is less attractive for the plaque deposition when it compare to the metals. Zirconia itself has many advantages as a biomaterial but also has frequent mechanical problems when it use for abutment of internal connection implant. For prevention or reduction of mechanical failures, use of titanium-link with zirconia super-structure which part that connects directly into the implant can be a good alternative. In this literature, I would like to review the clinical considerations of use of titanium link - CAD/CAM zirconia abutment for dental implant in esthetically important areas.

This article described a procedure for fabricating an esthetic gingival porcelain restoration as an implant-supported fixed prosthesis for edentulous maxilla. Alternative treatments for fully edentulous patients include an implant-supported overdenture or a fixed implant-supported prosthesis with bilateral distal cantilevers. But, from a functional and biomechanical point of view, the fixed implant-supported prosthesis with posterior cantilevers or implant-supported tissue-borne overdenture do not significantly improve masticatory effectiveness compared with a distributed implant restoration as a fixed implant-supported prosthesis. The fact that the prosthesis is supported by distributed implants over eight for edentulous maxilla in general, provides increased masticatory efficiency as a fixed restoration and similar gingival appearance with esthetic gingival porcelain. It is also detachable by dentist to allow easier after-care of soft tissue and the prosthesis.

심미의 기준은 시대와 문화 그리고 개개인의 주관적인 관점에 따라 각기 다를 수 있다. 하지만 심미적인 부위를 수복하는 치과의사로서 일반적으로 따라야 할 원칙과 기준들이 있으며 수복물의 형태와 주변치아와의 조화 등을 위해 캐드캠의 몇몇 기능들은 아주 유용한 것으로 보이며, 전통적인 작업 방식에 비해 효율성도 높은 것으로 보인다. 또한 전치부 임플란트에서 치은이 얇은 경우 기계적인 문제를 줄이면서도 지르코니아 등의 도재를 사용하기 위한 한 방법인 링크 지대주에 대해 함께 알아보려 한다.

성공적인 심미치과치료를 위해서는 종종 교정과, 치주과, 보철과의사의 협진치료가 필요하다. 상실된 치아를 수복하는 경우, 특히 심미가 중요시되는 전치부의 상실치 수복시 임상가는 여러가지 치료방법의 장단점을 고려하여 치료법을 선택해야 한다. 이 글에서는 선천결손된 상악측절치와 발치가 필요한 구치를 가진 환자를 치아교정과 임플란트 수술 그리고 임플란트 보철의 다학제간 진료로 치료한 증례를 보여드리고자 한다.

일반적인 보철치료 과정에서 치과의사와 치과기공사 간의 의사소통 부족으로 인한 재치료 사례가 빈번하게 일어나고 있다. 대규모 치료의 성공은 작은 치료에서 부터 시작한다. 이 보고서에서는 그것과 관련한 간단한 사례를 통해 커뮤니케이션의 중요성을 되새긴다. 좀 더 나은 색과 형태를 재현하기 위해서 치과의사는 치과기공사에게 구체적이고 정확한 정보와 의견을 전달해야 하고 치과기공사는 이것을 올바로 분석하고 제대로 표현할 수 있는 기술을 보유해야 한다. 이 과정에서 반드시 서로가 의견교환을 통해 좀더 나은 보철을 제작할 수 있는 환경을 구축해야 한다.

Migration of dental implants into the maxillary sinus is uncommon. However, poor bone quality and quantity in the posterior maxilla can increase the potential for this complication to arise during implant placement procedures. The aim of this report is to present a dental implant that migrated into the maxillary sinus and disappeared. A 53-year-old male patient was referred to us by his dentist after a dental implant migrated into his maxillary sinus. The displaced implant was discovered on a panoramic radiograph taken five days before his referral. Using computed tomography, we determined that the displaced dental implant was not in the antrum. There was also no sign of oroantral fistula. Because of the small size of the displaced implant, we think that the implant may have left the maxillary sinus via the ostium.
