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.

Infective endocarditis (IE) caused by methicillin-resistant Staphylococcus aureus (MRSA) has become a worldwide concern. We present a case of a 12-year-old child with IE of the native mitral valve due to MRSA infection after an invasive dental procedure. Based on the clinical symptoms and the presence of cerebrospinal fluid pleocytosis, the patient was initially diagnosed with presumed bacterial meningitis and treated with empiric antibiotics. On the third day of hospitalization, MRSA was cultured from the initial blood samples and vegetation was observed on the mitral valve during an echocardiogram, findings which are compatible with a diagnosis of IE. The revised guidelines for antibiotic prophylaxis for the prevention of IE advise that IE prophylaxis for dental procedures is reasonable only for patients with underlying cardiac conditions, who are at the highest risk of adverse outcomes from IE. However, in this case, the patient had no high risk factors indicative of IE prophylaxis, except for mitral valve prolapse. She had no recurrence of IE over a follow-up period of 12 months.

Infective endocarditis is a life-threatening disease, although it is relatively uncommon. Substantial morbidity and mortality result from this infection. Therefore, primary prevention of endocarditis whenever possible is very important. The American Heart Association updated recommendations for the prevention of infective endocarditis in individuals at risk for this disease in 1997. But, utilization of antibiotic prophylaxis for patients at risk does not provide absolute immunity from infection. This report presents the case of infective endocarditis that occurred in spite of appropriate antibiotic prophylaxis in the ventricular septal defect(VSD) patient.

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 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.

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.

The purpose of this study was to examine the satisfaction level of patients with oral health care provided by a dental hospital, especially scaling, and their oral health behavior. The subjects in this study were 263 college students who were in their 20s and selected from among patients who visited D university dental hospital in Gangwon Province during the oral prophylaxis practice of dental hygiene sophomores and juniors. The findings of the study were as follows: 1. Whether the selected students had ever had their teeth scaled was checked, and those who had outnumbered the others who hadn't. The rates of the former and latter respectively stood at 61.2 percent and 38.8 percent. Regarding places where they got their teeth scaled, the majority of the students that represented 75.2 percent did that at dental clinics. By gender, 34.4 percent of the male students did that at schools, which were larger than 11.8 percent of the female students who did. 88.2 percent of the female students did that at dental clinics, which were larger than 65.5 percent of the male students who did. Gender made significant differences to that(x2=10.79, p<.01). 2. As for satisfaction level with scaling by gender, the male students (38.7%) who had no specific idea outnumbered the female students (26.5%) who did. The female students(57.4%) who felt no pain during scaling outnumbered the male students(55.9%) who did. Gender made a significant difference to their responses. (x2=6.38, p<.05). 3. Concerning the use of oral hygiene supplies, most of the students who represented 72.2 percent had never flossed their teeth, and as many as 86.3 percent had never used a tongue cleaner. But the gaps between them and the others were not statistically significant.
