This paper reviewed the following subheadings and a few selected references in each section were discussed: ${\cdot}$ Sealant placed over caries; is it possible? Initial caries which is not sticky during proving is possible to be placed with sealants. ${\cdot}$ Prophylaxis of fissure; which method is most effective? Mechanical preparation with fissurotomy or resin polishing bur is one of the most effective method to clean the pit and fissure. ${\cdot}$ Glassionomer cement as a sealant; GIC, wheather it released fluoride or not, cannot be as cost-effective as resin-based sealants. ${\cdot}$ Sealant products; Color(white vs opaque), fluoride(containing vs not), filler component(filled vs non-filled) do not influenced the quality and retention of sealants. ${\cdot}$ Use of intermediate bonding agent to improve retention; Intermediate bonding may increase the retention rate of sealants ${\cdot}$ Penetration method of sealants; Several methods including waiting before light curing are recommended.

최근 전 세계적으로 메티실린내성 황색포도알균(methicillin-resistant Staphylococcus aureus [MRSA])에 의한 감염성 심내막염의 빈도가 증가하는 추세이다. 저자들은 12세 여아가 침습적 치과 치료 이후에 발생한 MRSA에 의한 감염성 심내막염 1예를 경험하였기에 보고하는 바이다. 환아가 경부강직을 나타내어 시행한 뇌척수액 검사상 세포 증가증 소견이 보였고 세균성 수막염을 의심하여 항생제 치료를 시작하였으며, 입원 3병일째 혈액 배양검사에서 MRSA가 검출되었다. 심장 초음파상 승모판막의 전엽에 붙어있는 증식조직이 증명되어 항생제 치료 후 호전되어 퇴원하였다. 개정된 심내막염 예방을 위한 가이드라인에서는 오직 고위험군에서만 치과 처치 전에 예방적 항생제 요법을 권장하고 있다. 본 증례는 승모판 탈출증 이외에 고위험군이 없었던 환아에서 잇몸의 출혈을 유발하는 치과 치료를 받은 이후에 발병한 감염성 심내막염의 경우로서, 이후 12개월간 감염성 심내막염의 재발은 없었다.

감염성 심내막염은 치과치료로부터 발생할 수 있는 심각한 심장질환 합병증이며, 생명을 위협하는 치명적인 상황을 초래할 수 있다. 따라서 심내막염 예방을 위하여 위험군에 속하는 환자에서 침습적 술식을 행하기에 앞서 예방적 항생제를 전투여한다. 본 증례는 영구치 근관치료 후 발생한 감염성 심내막염을 주소로 내원한 환아로서 심실중격결손으로 인해 예방적 항생제를 투여했음에도 불구하고 심내막염이 발병하여, 항생제 요법 후 의심되는 원인치아를 발거하고 심장수술을 시행하였다. 이에 다소의 지견을 얻었기에 보고하는 바이다.

Purpose : The purpose of this clinical study was to evaluate the effect of chelating and deproteinizing agent containing dental conditioning gel on alleviation of peri-implant mucosa inflammation. Methods: 36 patients with functionally loaded implants for at least 1 year and have clinical signs of peri-implant mucositis were recruited. At baseline, all implants received subgingival prophylaxis with ultrasonic scaler. In the test group, patients were provided a chelating and deproteinizing agent dental conditioning gel (Clinplant$^{(R)}$) and were given instructions to applicate it around the implants using an interdental brush for 2 weeks. Chlorhexidine and saline were provided to the positive control group and negative control group, respectively. The modified sulcus bleeding index (mSBI), modified plaque index (mPI), and probing pocket depth (PPD) were evaluated at baseline, 1 week, and 2 weeks. Results: In the Clinplant$^{(R)}$ and chlorhexidine group, mSBI (-0.81, -0.85 respectively; p<0.01), mPI (-0.46, -0.5 respectively; p<0.01), and PPD (-0.58, -0.48 respectively; p<0.01) at 2 weeks were significantly reduced from baseline. In the saline group, all the clinical parameters were reduced but there was no statistical significance. The saline may be attributed to the influence of prophylaxis at baseline. Conclusions: The present study demonstrated the beneficial clinical effects of chelating and deproteinizing agent containing dental conditioning gel to decrease peri-implant mucosa inflammation equivalent to chlorhexidine. This dental conditioning gel might be useful for alleviation of peri-implant mucosa inflammation.

The objective of this research was to evaluate a curriculum for dental hygiene program, and to develop a clinical dental hygiene course. Learning objectives of dental hygiene program was used as the measure of courses related to clinical dental hygiene. Dental hygiene process is now recognized as a standard of education and practice of clinical dental hygiene. This study demonstrated that we have to integrate oral prophylaxis and preventive dentistry based on dental hygiene process for clinical dental hygiene education curriculum. And the results indicate that competency in comprehensive dental hygiene care is a priority for dental hygiene program.

The government developed National Competency Standards and expands field friendly education for innovation of industrial field based education training. NCS is the national level of standards that the government systemized knowledge, skills and attitudes required to work in industrial fields by each industry and each level. This study was intended to research NCS education contents of an introduction of dental hygienics, which is a basic major subject among subjects of dental hygiene course, to present learning goals accordingly, and to be used as a basic resource of NCS field oriented classes of dental hygienists through the comparison before and after. In case of the dental hygiene course, dental hygienists are performing important core tasks as clinicians at dental offices. Therefore, such comprehensive and professional performance abilities as scaling, oral prophylaxis and oral health education are required at the fields. The education process and education contents for this should be researched continuously.

Objectives: This study evaluated color differences (${\Delta}Es$) and translucency parameter changes (${\Delta}TPs$) of various computer-aided design/computer-aided manufacturing (CAD/CAM) blocks after immersion in coffee. Materials and Methods: Eight CAD/CAM blocks and four restorative composite resins were evaluated. The CIE $L^{\ast}a^{\ast}b^{\ast}$ values of 2.0 mm thick disk-shaped specimens were measured using the spectrophotometer on white and black backgrounds (n = 6). The ${\Delta}Es$ and ${\Delta}TPs$ of one day, one week, and one month immersion in coffee or water were calculated. The values of each material were analyzed by two-way ANOVA and Tukey's multiple comparisons (${\alpha}=0.05$). The ${\Delta}Es$ after prophylaxis paste polishing of 1 month coffee immersion specimens, water sorption and solubility were also evaluated. Results: After one month in coffee, ${\Delta}Es$ of CAD/CAM composite resin blocks and restorative composites ranged from 1.6 to 3.7 and from 2.1 to 7.9, respectively, and ${\Delta}TPs$ decreased. The ANOVA of ${\Delta}Es$ and ${\Delta}TPs$ revealed significant differences in two main factors, immersion periods and media, and their interaction except for ${\Delta}Es$ of TEL (Telio CAD, Ivoclar Vivadent). The ${\Delta}Es$ significantly decreased after prophylaxis polishing except GRA (Gradia Block, GC). There was no significant correlation between ${\Delta}Es$ and water sorption or solubility in water. Conclusions: The ${\Delta}Es$ of CAD/CAM blocks after immersion in coffee varied among products and were comparable to those of restorative composite resins. The discoloration of CAD/CAM composite resin blocks could be effectively removed with prophylaxis paste polishing, while that of some restorative composites could not be removed.

구강진료기관에서의 개인방호의 중요성을 일깨우기 위해 보건대학 치위생과 3학년 재학생을 대상으로 치면세마와 엑스선 촬영 실습 수행과정에서 감염관리 및 엑스선안전관리에 대한 실천 정도를 조사하여 아래와 같은 결과를 얻었다. 1. 치면세마 실습시에는 감염관리에 대해 높은 수준으로 인식하고 철저히 수행하고 있었다. 2. 엑스선촬영 실습시에 감염관리의 필요성에 대한 인식 정도는 비교적 낮았다. 3. 엑스선촬영 실습시에는 필름유지기구를 제외하고는 거의 감염관리를 하지 않고 있었다. 4. 엑스선촬영 실습시에 엑스선안전관리에 대해서는 높은 수준으로 인식하고 실천하고 있었다. 이상의 결과를 종합해 볼 때 엑스선촬영시에는 거의 감염관리가 이루어지지 않고 있다는 것을 알 수 있다. 완벽한 감염관리를 위해 엑스선촬영시에도 철저한 감염관리가 이루어질 수 있도록 필요성에 대한 인식제고와 실천율을 높일 수 있는 교육의 강화가 요구된다.

Rhinoliths are foreign bodies composed of mineralised deposits in the nasal cavity that are rarely encountered in routine dental practice. The current report presents a case of a 77-year-old female patient who visited a dental treatment centre for a routine dental check-up and prophylaxis. On the clinical examination, the patient did not report any breathing difficulty, nasal obstruction, or any form of discharge. Panoramic radiography showed a horizontally magnified radiopaque structure in the right nasal fossa region. Cone-beam computed tomography (CBCT) revealed a hyperdense entity with a laminated presentation in the right nasal fossa. The hyperdense entity was diagnosed as a rhinolith based on the radiographic findings. Although the patient was asymptomatic, a referral was made to an ear, nose, and throat surgeon for a further evaluation. This report highlights the importance of CBCT imaging in the diagnosis of soft-tissue calcifications.
