Comparative effects of aqueous single-phase and oil-water two-phase mouthrinses containing bamboo salt, magnolia bark and Centella asiatica extracts on reducing gingivitis: a randomized clinical trial / 대한구강보건학회지

OBJECTIVES: The aim of this study was to assess the antiplaque and antigingivitis effectiveness of aqueous single-phase and oil-water two-phase mouthrinses, containing bamboo salt, magnolia bark, and Centella asiatica extracts, in Korean adults. METHODS: In this double-blinded clinical trial, a total of thirty-four participants aged over 19 years were randomly allocated to three experimental groups: 1) control group; 2) aqueous single-phase mouthrinse (ASM) group, and; 3) oil-water two-phase mouthrinse (OTM) group. The experimental mouthrinses all contained sodium fluoride, and the ASM and OTM contained additional ingredients of bamboo salt, magnolia bark, and Centella asiatica extracts. For the OTM, 50% essential oil was added to create an oil-water two-phase mouthrinse. A two-week randomized crossover design with a two-week washout period was applied. Following a complete dental prophylaxis, participants were instructed to use the prescribed mouthrinse twice daily for two weeks as an adjunct to their usual mechanical oral hygiene procedures. Pre- and post-experiment clinical examinations were performed to measure the plaque index (PI) and bleeding on probing (BOP) for the full mouth. Paired t-test was applied to compare the intergroup differences for all clinical variables. RESULTS: Compared to the control group, ASM showed a significantly reduced BOP (P<0.05). However, there was no statistically significant difference in the effects of the three mouthrinses on reducing the PI. CONCLUSIONS: The results of this study indicate that the use of an aqueous, single-phase mouthrinse containing bamboo salt, magnolia bark and Centella asiatica extracts could help alleviate gingivitis.

Oral health beliefs and cultural specificity in multicultural families / 대한구강보건학회지

OBJECTIVES: The aim of this study was to evaluate the oral health beliefs and cultural specificity of multicultural families. METHODS: Subjects were 179 adults from multicultural families living in Gwangjin-gu, Seoul. The surveys and interviews were performed between June and November 2014 in the subjects' native languages (English, Chinese, Vietnamese, and Korean). The surveys were conducted using a self-administration method and a face-to-face interviewing method with the assistance of translators. RESULTS: Perceived barrier of oral health belief scores were higher in Vietnamese and Korean spouses than those from other countries (P<0.05). Cultural specificity scores were highest among the Japanese and lowest among the Vietnamese (P<0.01). CONCLUSIONS: Multicultural families showed different oral health beliefs and cultural specificities. Therefore, future oral health care programs for multicultural families should consider cultural differences and adaptations.
