Early childhood caries is a global healthcare concern in developing and industrialized countries. If left untreated, it leads to immediate and long-term complications that affect the well-being and quality of life of concerned families. Therefore, many preventive and treatment approaches are available to the healthcare provider to curb this virulent form of caries. After behavioral interventions, general anesthesia is used in specific settings when a young patient presents with extensive teeth damage and exhibits a lack of cooperation that is incompatible with conventional dental office care. However, without proper follow-up, any positive results might be lost over time.

The periodontal diseases and dental caries are major infectious diseases in oral cavity. Many of the preventive and therapeutic dental products contain the antimicrobial and anti-inflammatory components. But some of these antimicrobial have weak points such as coloration, burning sensation and insolubility in water. We have screened the therapeutic herbal extracts of the Plant Extract Bank for the antimicrobial activity on the major dental pathogens by growth inhibition assay. For the Porphyromonas gingivalis, 8 herbal extracts had an antimicrobial activity, 11 herbal extracts for the Prevotella intermedia, 43 herbal extracts for the Haemophilus actinomycetemcomitans and 61 herbal extracts for the Streptococcus mutans. Among these extracts, 6 herbal extracts had an antimicrobial activity for more than 3 species of dental pathogens. These extracts are Araliae Cordatae Radix, Crassirhizomae Rhizoma, Mori Radicis Cortex, Psoraleae Semen, Pini Ramulus and Sieges- beckiae Herba. All of effective extracts were CA group, ethanol extracts. Among these 6 herbal extracts, only Crassirhizomae is known to have a antibacterial effects. Therefore these herbal extracts have a possibility to be a candidate for a major antibacterial components in dental products.

The purpose of this study was to obtain the basic data for oral health program planning of the totally blind persons. The author had surveyed oral health status and dental needs of 268 totally blind persons aged from 7 years old to 29 in Seoul, Korea, Thereafter, the toothbrushing frequency, df rate, dft index, DMF rate, DMFT index, restorative treatment requirement, bridge status, periodontal status, and periodontal requirement were calculated and discussed. The obtained results were as follows: 1. The average toothbrushing frequency was 2.53 times a day, and the average toothbrushing frquency after eating was 2.12 times a day. 2. DMF rate was 53.73%, and DMFT index was 2.12. 3. the average number of teeth required restorative treatment due to dental caries was 1.95. 4. Oral hygiene instruction was required in 15.30%, oral porphylaxis and oral hygiene instruction in 58.58%, periodontal therapy in 10.14%. %. Incremental dental care system was recommended to improve dental health status of the totally blind persons.

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.

Dyke-Davidoff-Masson syndrome is a non-inherited rare condition that presents during childhood and is characterized by seizures, hemiplegia, mental retardation, cerebral hemiatrophy, calvarial thickening, and hyperpneumatization of the frontal sinuses. The present article highlights a case of a 12-year-old male child with additional clinical findings of $caf{\acute{e}}$-au-late pigmentation and ocular lipodermoid. This is the first case report of DykeDavidoff-Masson syndrome to describe oral manifestations, such as unilateral delayed eruption of teeth, hypoplasia, and taurodontism, which could be unique and characteristic of this condition. Oral health care providers and physicians should be aware of these oral observations as dental referrals could warrant early dental prophylactic care and can be useful in diagnosing the possible time of injury and type of Dyke-Davidoff-Masson syndrome.

Astaxanthin is one of many carotenoids present in marine animals, vegetables and fruits. Since carotenoids are known to exert antioxidant actions, we explored to determine if astaxnathin could have such regulatory actions in normal-and $CCl_4$-treated rat liver. Astaxanthin treatment caused a slight increase in $\alpha$-tocopherol levels in the control rat liver. Glucose-6-phosphatase activity was significantly increased by astaxanthin in a dose-dependent manner and its activity decreased in response to $CCl_4$treatment was slightly inhibited by astaxanthin. These results suggest that astaxanthin could protect liver damages induced by $CCl_4$via inhibiting lipid peroxidation and it may have a potential to activate the anti-oxidant system of normal liver by stimulating $\alpha$-tocopherol production.

Objectives: The purpose of this study was to investigate influences on employment preparation in dental hygiene students. Methods: A self-reported questionnaire was completed by 386 dental hygiene students in South Korea from November 1 to 30, 2016. For data analysis, the study used independent t-tests, one-way analysis of variance, Pearson correlation analysis, and regression analysis among others. Results: Students with higher grades tended to have major satisfaction, instruction participation, and employment preparation (P<0.001). Higher parental monthly income was related to higher major satisfaction (P<0.001). Employment preparation was significantly positively related to major selection motive, major satisfaction, and instruction participation. Conclusions: In order to encourage dental hygiene students to prepare for employment, it is necessary to create a better academic environment and develop a variety of employment preparation education programs. I think that the active interest of the country, society, school, and family will have a positive impact on employment preparation.

Authors have selected a physiological bad breath patient( 62 years old, male ) among the bad breath outpatients who have visited the halitosis control clinic in Korea University Medical Center(KUMC). The patient visited the halitosis control clinic for his oral malodor control, 3 times from April to June in 2018, and in August the patient visited to KUMC malodor control clinic again for his assessment of his two months efforts. Getting the data about the patient's endeavor to get over his physiologic oral malodor and the estimation of the patient's satisfaction level at his oral malodor improvement by a questionnaire method, and the organoleptic level assessment by the dentist, then we could propose an estimation method of the physiologic oral malodor patient care prognosis.

Fuji VII is a glass-ionomer cement specially targeted for early protection in erupting first and second molars. Properties of Fuji VII such as very high level of fluoride release, low viscosity and no need to preliminarily etch the substrate would be useful to erupting molars with primary pit and fissure caries or hypoplastic area for preventive goal or remineralization. The purpose of this study were to evaluate remineralization of Fuji VII glass ionomer cement and to compare with one of other restorative materials such as conventional glass ionomer cement, resin-modified glass ionomer cement, compomer and composite resin. Forty-two extracted human molars were used for this study. All teeth were immersed in demineralizing solution for 48 hours after Class V cavity preparation was made on sound proximal surface. The teeth were randomly divided into six groups and restored with Fuji VII, Fuji II, Fuji II LC improved, F2000, $Filtek^{TM}$ Z250 and control group was unrestored. The middle area with $130{\pm}20{\mu}m$ thickness was separated from specimen using microtome and demineralized area was photographed under polarized microscope. Separated area was relocated to specimen and stored in artificial saliva, After four weeks, changes of demineralized area were observed and compared to them restorated immediately. The results from the this study can be summarized as follows ; 1. Fuji VII, Fuji II, Fuji II LC improved have more prominent remineralization effect than F2000, $Filtek^{TM}$ Z250, control group. 2. No significant differences in remineralization effect are seen between Fuji VII and Fuji II, Fuji II LC improved.
