The purpose of this study was to compare the color of maxillary primary central incisors, lateral incisors, canines with the color of various composite resins using a spectrophotometer VITA Easyshade^®V. One researcher measured the color of sound maxillary primary anterior teeth of 100 children aged 1 to 6 and specimens which were made by composite resins with a total of 10 types and 31 shades, and CIE L^*, a^*, b^* values were obtained. There was no clinically recognizable color difference between the maxillary primary central and lateral incisors. However, the maxillary primary canines showed difference in color above the clinical acceptability threshold with the primary central and lateral incisors. These findings showed no significant color differences between men and women, and no significant color changes with age. A1 shade is the most common in all maxillary primary anterior teeth. Composite resins, which are thought to be similar to the color of maxillary primary anterior teeth were selected from 9 types of maxillary primary central incisors, 6 types of primary lateral incisors, 6 types of primary canines.

Application of digital technology in dental treatments can simplify the treatment process and reduce patient discomfort. In regards of digital complete dentures, several commercial systems are available. However, these systems are not being routinely applied in Korea. In this case report, comparative analyses were performed regarding the two sets of complete dentures fabricated in digital and conventional workflow in a single patient. Complete dentures made with digital workflow were able to form an ideal occlusion because customized teeth were used. Compared to that, there were also limitations such as lower retention of mandibular dentures, so we would like to report this.

Etiologies and traditional treatment modalities regarding anterior open-bite were discussed to elucidate the advantages and disadvantages. And an emphasis was placed on the understanding of the true nature of anterior open-bite. Most anterior open-bite malocclusions can be treated with a high degree of sucess and stability without surgical intervention with the congnizance of the anatomy, the physiology and the dynamics of orthodontic mechanotherapy. In this regard, a Multiloop Edgewise Arch Wire (MEAW) Technic, which has been developed during the past twenty years by Dr. Kim, was introduced. Three cases with anterior open-bite malocclusion were presented to demonstrate the mechanotherapy.

Digital dentistry is becoming a mainstream of dental practice. We are already used to intraoral scan, guided implant surgery, manufacture of prosthesis (CAD-CAM) in our daily practice; those are not sensational anymore. However, treatment planning with digital simulations is not spotlighted enough. In this report, a digital mockup was utilized to visualize the final goal of maxillary rehabilitation including all anterior and posterior teeth, and persuade a patient who wanted restoration of only anterior teeth. We will also discuss the use of digital mockup and its actual copy as the guide of altered vertical dimension through the clinical process.

Thermoformed appliance, which has been recently introduced for dental usage, is an appliance made of thermoformed sheets and formed with positive or negative pressure under heat. Thermoplastic material is a kind of plastics and can be repeatedly softened by heat. It is classified into hard elastic foil, hard/soft compound foil and soft elastic foil, including BIOPLAST, BIOCRYL, IMPRELON, etc. It has been developed in 1969 and is available in various thickness, shape and color. There are two types of Vacuum former for thermoplastic materials; the pressure type and suction type. The former is much better than the latter for fabrication of various appliances due to its higher pressure. The authors have applied these appliances to some cases - chin cap, active retainer, individual Fluoride tray, mouth protector, bracket transfer mask, bruxism splint(night guard), Essix appliance - by pressure type Vacuum former($Biostar^{(R)}$). The thermoplastic appliances have numerous advantages such as simple procedure, short working time, clean and transparent product, less objectionable taste. But its outstanding advantage would be its excellent biocompatibility bacause it has no monomer and hence no tissue irritation. Although there is some limitations in its usage, it can be used widely for various purposes especaily for pediatric dentistry.

The evaluation of occlusion using digital methods is easier and simpler in terms of recording, comparison, analysis, and objectivity compared to existing methods such as articulating paper and occlusion foil. The purpose of this case report was utilizing the digital method for evaluating occlusion. The occlusion of patient requiring full veneer crown restoration was evaluated using an intraoral scanner (i500, Medit, Seoul, Korea) at every visit. The occlusion was also assessed using conventional articulating paper and a digital occlusal analysis system (Dental prescale II, GC corp., Tokyo, Japan) for comparison. Throughout the treatment process, the intraoral scanner and the conventional articulating paper method showed similar outcomes. The results suggest that the use of digital evaluation system is highly probable in the near future.

목적 : 현재 우리 사회는 건강증진에 대한 욕구가 증가함에 따라 보건의료에서 질적 서비스향상이 요구되고 있고, 구강진료를 분담하는 치과위생사들도 보다 전문적인 역할을 수행하기 위해서는 지식과 기술의 수준향상이 필요하다. 이에 치과위생사의 질적 수준을 향상시키는 데 가장 빠르고 효과적인 방법이 국가시험제도이며 국가시험에서의 타당성과 신뢰성을 높이고 필요한 과목과 내용을 직무를 중심으로 조정한다면 가장 좋은 방법이라고 사료되어 현행 우리나라 치과위생사 국가시험제도에 따른 문제점을 파악하고 캐나다 국가시험 제도와의 비교를 통해 문제점을 분석하고 이에 따른 개선책을 알아보았다. 방법 : 전국 치과위생사 교육기관에 근무하는 교수와 의료기관에 종사하는 치과위생사 중에서 최근 국가시험 응시경험자를 대상으로 2008년 6월 9일부터 6월 23일까지 설문조사를 실시하였으며 E-mail 과 Fax를 이용하였다. 캐나다 국가시험제도는 National Dental Examinations American Dental Association. National Board Dental Hygiene Examination Candidate Guide자료를 사용하여 비교하였다. 자료의 분석은 SPSS통계프로그램(Version 11.0)을 이용, Chi-square 검정을 하였으며, Fisher's Exact Test에 의한 검정을 실시하였다. 결과 : 1. 국가시험과목구성은 현행 국가시험과목구성에 문제가 있는 것으로 사료되어 과목조정 필요성이 큰 것으로 나타났고, 특히 대학근무자가, 나이가 많을수록, 재직기간이 길수록 더 높았다. 2. 국가시험 문제의 유형은 암기해석 문제가 대부분이었고 난이도는 비교적 양호하였으며, 전문성도 있는 것으로 조사되었다. 3. 과목조정 필요성은 구강생물학개론, 치과임상학 순으로 상대적으로 높았다. 캐나다 국가시험과 비교해 보면 치과임상학과 구강위생학개론 분야의 조정이 더욱 필요한 것으로 나타났다. 4. 한국과 캐나다의 국가시험제도는 형식은 비슷하나 내용과 과목의 구성에서는 큰 차이가 있었다. 5. 캐나다의 국가시험과 비교 시 한국은 치과위생사의 포괄적인 치과위생관리능력을 평가하기 어려웠다. 결론 : 이상의 결과로 보면 현행 국가시험은 과목 구성이 부적절하므로 조정의 필요성이 시급한 것으로 조사되었으며, 캐나다 국가시험과는 과목구성에서 큰 차이가 있었고 치과위생사에게 요구되는 포괄적 치과위생관리능력을 평가할 수 없는 것으로 조사되어 현행 국가시험 개선이 요구되었다.

Minor orthodontic treatment using a thin wire with high elasticity can shorten the treatment period and reduce the load on the anchorage by the application of light force. Since it can be applied immediately without a dental laboratory procedure and does not require the patient's cooperation, it can be clinically useful. The cases reported here have led to positive results in short periods of treatment, using only a segmented straight 0.012 inch NiTi wire and flowable resin to address various locations within the oral cavity, such as the anterior teeth, premolars, and molars.
