Objectives: This study aimed to provide basic data for the improvement and management of the oral health awareness and oral-health-related quality of life of immigrant women in multicultural families. Methods/Statistical Analysis: This study targeted a total of 130 immigrant women in multicultural families who participated in the South Korean society adaptation programs at the multicultural family centers. The direct interview methods were used, and a questionnaire translation for each of the subjects’ countries of origin was prepared so that the subjects can answer the questionnaires by themselves. The collected data was used the SPSS 19.0 (ver) statistical program. Findings: The subject immigrant women in multicultural families in this study were aware of the importance of oral health depending on whether or not they visited a dental clinic after their migration, but even though their migration period was long, as their opportunity to receive education through oral-health-related programs was limited, there were very few persons who received such education. In addition, for the path through which they obtained oral-health-related knowledge, the mass media was the most common. This means that it is difficult for people with economic difficulties to access the oral care institutions in South Korea; thus, the probability that they will obtain unverified related knowledge through the mass media and not through professional education is high. Improvements/Applications: Establishment of oral healthcare programs for immigrant women in multicultural families and regional linkage between the multicultural centers and the health centers and dental clinics are urgently needed.Keywords

Objectives: This study aims to investigate the halitosis increase after solid and liquid food intake, and to determine the type of food that aggravates halitosis. Methods/Statistical Analysis: A total of 60 healthy women filled out the survey questionnaire. Their normal halitosis levels and the levels after food intake were also measured using a Bad Breath (B/B) checker, and these were then compared. Findings: The survey revealed that the food that was expected to most likely increase halitosis was coffee mix (75%). On the other hand, the intraoral gas (OG) measurement using a B/B checker revealed that the food that increased halitosis the most after intake was cola, followed by coffee mix, orange juice, candy, chocolate bar, and gum, in that order. The study results showed that the halitosis increased the most after cola intake, and that liquid foods caused more halitosis than solid foods. Improvements/Applications: The study results showed that liquid foods caused more severe halitosis than solid foods. Therefore, it is recommended that solid foods be preferred to liquid foods to reduce halitosis.Keywords

Propolis is a natural substance which is produced from honey bees through collecting and transforming resins and exudates from plants. The propolis can use the medicine field for antibacterial effect. The purpose of our study was to investigate the antibacterial activity for the oral prevention of dental caries. The propolis was from Australia honeybees, diluted 5w% and 10w% in ethanol. The antibacterial activity of the treated propolis against Streptococcus gordonii(S. gordonii), Streptococcus intermedius(S. intermedius) and Streptococcus sanguinis(S. sanguinis) were determined using optical density and colony forming units. All experimental groups were effective against bacteria. Streptococcus intermedius and Streptococcus sanguinis were more effective compared to Streptococcus gordonii. All groups inhibition bacterial growth, but there were no significant differences of different wt% groups. There were significantly low activities treated with propolis. The antibacterial activity indicated propolis against Streptococcus gordonii, Streptococcus intermedius and Streptococcus sanguinis. Propolis possesses several medicinal properties. In this study, the 5 wt% and 10 wt% group of propolis was indicated antibacterial effects, which succeeded in inhibiting the bacteria growth. Our study showed a significant effect related to oral bacteria species. In conclusion, the antibacterial action observed in this study suggests that this propolis substance could be used as an alternative medicine for infectious conditions of the oral disease without causing any major local or systemic adverse effects.Keywords

Background/Objectives: Many microorganisms reside in the oral cavity, and they are referred to as oral-resident bacteria. Oral microorganisms are an important cause of oral diseases, and as such, many studies have been conducted to control them. This study aimed to investigate the antimicrobial activity against S. intermedius and S. gordoii among the oral-resident bacteria using Coptischinensis, a natural extract.
Method/Statistical Analysis: To investigate the antimicrobial activity of Coptischinensis, the clear-zone confirmation method using filter paper and colony-forming unit (CFU) was used to check the bacterial proliferation. As the concentration of Coptischinensis increased, the size of the clear zone also increased. As a result of the CFU, bacterial proliferation was not observed in the experimental group as compared to the control group.
Findings: The results of this study proved the antimicrobial activity of Coptischinensis against the oral-resident bacteria S. intermedius and S. gordoii. The clear zone results showed that S. intermedius and S. gordoii were larger in size than the control group.CFU showed a large amount of colony in the control group but not exist colony in the experimental group.The result showed its potential as an antimicrobial agent applicable to oral-resident bacteria.
Improvements/Applications: S. intermedius and S. gordoii bacteria found in the oral cavity showed antimicrobial effect on the extracts. Coptischinensis was confirmed to be a preventative and therapeutic agent of tooth decay. In conclusion, the possibility that it can be applied to various intraoral antibacterial products in the future.
