Bamboo salt is a special processed salt by Korean traditional recipe. Recent study results showed that bamboo salt or bamboo salt with some other materials like herbal extracts have the anti-microbial activity, inhibition effects of dental plaque and gingival inflammation. Bamboo salt also showed anti-cariogenic effects; remineralization and acid resistance. Compare to fluoride toothpaste, bomboo salt toothpaste with fluoride showed the more effective remineralization on inner part of the early dental caries lesion. It increased the surface hardness and decreased lesion depth of early dental caries lesion. Thus, it is suggested thai bamboo salt could be used as a anti-microbial, anti-plaque, anti-inflammatory and anti-cariogenic material for oral disease prevention. Especially, bamboo salt dentifrice with fluoride can be recommanded as a useful remineralizing agent.

Desquamative gingivitis (DG) is a gingival manifestation of systemic mucocutaneous disorders such as mucous membrane pemphigoid, oral lichen planus, and pemphigus vulgaris. The lesion is very painful, so affects the patient's ability to do proper oral hygiene practices. This may be a potential risk factor for long-term periodontal health. However, there is some controversy about the relationship between the existence of DG and periodontal status. Although the correlation between DG-associated diseases and periodontal status is not to be certain, early diagnosis and appropriate treatment including adequate plaque control and removal of local factors is very important for preventing the progression of diseases and destruction of periodontal tissues.

In the last decade, the replacement of old PFM restorations has been a common dental procedure, especially on the anterior regions. Gingiva conditions in most re-treatment cases are not healthy with the old restorations due to ill-fitting margin, improper tooth reduction and poor oral hygiene. Practitioners must carefully evaluate and manage periabutmental gingiva for final restorations. The role of provisional restoration became a major clinical concern at this point. Well-fabricated provisional restorations with precise-fit margin and proper anatomy are critical for achieving good gingival health. Thus, the key of success in replacing old PFM crown depends on the proper tissue management by precise provisional restorations.

After extraction of tooth, alveolar ridge resorption is inevitable in most cases. Clinicians confront with horizontal and vertical resorption of alveolar bone. Without massive amount of bone and soft tissue graft, dental implant will be placed apically to gain stability. In those cases, not only white esthetic part, but also pink esthetic part should be restored with pink porcelain. The margin of prosthesis should be located apically to reproduce natural look with adjacent teeth. However, when the margin is located apically, it is always hard to remove remaining cement, thus complications may arise. In this report, a novel design of implant prosthesis is introduced to solve those issues. The novel design is consisted of zirconia framework with pink porcelain and separate crowns on top of the framework. It eliminates the possibility of cement remnants by bringing the crown margin coronally. Pink esthetic part is incorporated in abutment part instead of crown part and the screw hole is covered with separate crowns.

The present study was performed to investigate the excellent microbial anticaries substance, aminoglycoside antibiotic, which is more effective than chlorhexidine for the treatment of dental caries. The aminoglycoside antibiotic against Streptococcus mutans JC-2 from a novel alkaliphilic Bacillus alkalophilshaggy JY-827 exhibited no significant difference at the treatment concentration of $2.5{\times}10^{-7}M$, however, it inhibited the activity of the Streptococcus mutans glucosyltransferase by 70.2% and 99.8% at the concentrations of $2.5{\times}10^{-7}$M\;and\;2.5{\times}10^{-6}M$, respectively. Lineweaver-Burk plot of the inhibitory aminoglycoside antibiotic showed competitive inhibition, with $K_i$ value of $6.4{\times}10^{-6}$ M. The aminoglycoside antibiotic did not show any cytotoxicity against human gingival cells. To evaluate the industrial applicability of the aminoglycoside antibiotic, a toothpaste containing this substance was prepared and tested on the extracted human teeth. The inhibitory rate of tooth calcification and calcium ion elution by the aminoglycoside antibiotic were 50% and 2.5 times, respectively. These results suggested that the aminoglycoside antibiotic from Bacillus alkalophilshaggy JY-827 is an effective agent against dental caries.

Objectives: The purpose of this research is to examine oral pathogen distribution among elderly with dementia in a care facility to understand the importance of preventively managing oral diseases in terms of preventively managing senile diseases. Methods: From 11th August 2015 to 11th October 2015, gingival crevicular fluid was collected from 130 subjects consisting of demented/non-demented elderly people aged above 65 in care facilities located in the regions of Busan/Gyeonggnam. Based on collected data, real-time PCR analysis on oral pathogen was conducted. Results: The demented elderly group consisting of female patients aged from 0 to 79 indicated higher ratios of T. denticola in comparison to the non-demented elderly group, and the demented elderly group consisting of female patients aged above 80 indicated a high ratio of S. mutans. It was confirmed that P. gingivalis and T. forsythensis categorized under the red complex are correlated, and that bacterial species categorized under the orange complex and bacterial species categorized under the red complex are correlated. Conclusions: Because eldery people with demntia are exposed to periodontal disease and dental caries, their oral environments are more vulnerable. In order to improve such environments, it is necessary to provide care facility personnel with an opportunity to receive education to become aware of the importance of oral health, and it is also necessary to compulsorily assign dental hygienists to care facilities so that they can serve as personnel specializing in oral health management.

이 연구는 일부 아동들을 대상으로 일상생활구강영향지수와 구강건강관련행태, 구강건강상태를 조사하였으며, 일상생활구강영향지수에 영향을 미치는 요인을 파악하고, 서로간의 연관성을 알아보고자 2012년 3월부터 5월까지 인천광역시와 천안시 소재 일부 학교 아동 200명을 대상으로 설문조사를 하였다. 그 중 설문조사가 완료된 175명을 최종 분석대상으로 하여 SPSS WIN 20.0 프로그램을 이용하여 분석한 후 다음과 같은 결과를 얻었다. 일반적 특성과 C-OIDP 불편경험 항목 수, 구강건강관련 행태와 C-OIDP 불편경험 항목 수는 통계적으로 유의한 차이가 없었다(p>0.05). 그리고 C-OIDP 불편 경험 항목 수가 많을수록 충전유치치면과(p=0.024), 우식경험유치치면이 많고(p=0.049), 구강 내 전체충전치면과(p=0.021) 구강내 전체우식경험치면 역시 많은 것으로 나타났다(p=0.047). 이것은 객관적인 구강건강상태와 주관적 지표인 C-OIDP가 서로 관련성이 있음을 보여준다. C-OIDP 여덟 항목 중 영향빈도가 높은 것은 식사하기, 치아 닦기, 웃기 순이었으며, 구강 내 전체 우식경험치면수가 많고, 지난 한 달간 잇몸 통증을 경험한 대상자에서 C-OIDP 항목점수가 높았다. 이것은 C-OIDP가 우식과 치주 상태와 관련이 있음을 보여주는 것이다. 이 연구는 주관적 구강건강지표와 실제 구강건강과의 관련성을 본 연구로서 매우 의미 있는 연구이며, 앞으로 C-OIDP에 영향을 미치는 다양한 요인에 대한 연구가 필요할 것으로 생각된다.
