  • Objective: The purpose of this study was to examine the effect of commercially available fluoride-containing oral rinses on the corrosion behavior of titanium alloys, which are the main components of orthodontic miniscrews. Methods: Four commercially available oral rinses (solution A, pH 4.46/260 ppm fluoride; solution B, pH 4.41/178 ppm fluoride; solution C, pH 6.30/117 ppm fluoride; and solution D, pH 4.17/3.92 ppm fluoride) were tested on titanium alloy (Ti-6Al-4V) circular plates, and saline was used as the control. The open-circuit potential and potentiodynamic polarization of these materials were measured. Thereafter, all samples were evaluated under a field-emission scanning electron microscope. Results: Among the tested oral rinses, except solution D, the more the fluoride content was, the greater was the corrosion potential downtrend; the corrosion resistance of the titanium alloy sample was also lowered significantly (p < 0.05). Field-emission scanning electron microscopic analysis of the surface morphology of the titanium alloy samples revealed that all samples had some defects, crevices, or pitting after exposure to the oral rinses than before treatment. In particular, the samples in solution A showed the most changes. Conclusions: Commercially available oral rinses having a high fluoride concentration and a low pH may reduce the corrosion resistance of titanium alloys used in dental appliances such as orthodontic titanium miniscrews and brackets.

  • The purpose of this study was to investigate the comparative effects of subgingival irrigation using some oral mouth rinses on early healing process of periodontal inflammation. The study population consisted of 13 patients with periodontal inflammation and distributed into 4 groups. Oral hygiene instruction, delicate scaling and root planing were done and then irrigated per 3 days during 2 weeks in situ with 1 of 4 solutions ; normal saline, C31G, Benzotonium chloride and tetracycline. Examination regarding probing pocket depth, plaque index, sulcular bleeding index, gingival index, gingival recession and leukocytes differential count was performed. Evaluation was made at the baseline and 2 weeks after non-surgical periodontal therapy. The results were as follows : 1. Clinical indices including probing pocket depth, plaque index, sulcular bleeding index, gingival index and gingival recession were significantly improved from baseline to 2 weeks. But there was no significant differences among 4 groups. 2. PMNs percent on leukocytes differential count was significantly decreased from baseline to 2 weeks on all groups. Those of tetracycline and C31G were significantly decreased than those of normal saline group. These results suggest that clinical indices were not different, but the decrease of inflammation were significantly different among some mouth rinses.

  • Objectives: The purpose of this study was to investigate the factors affecting the use of oral hygiene products in infants. Methods: From October 2015 to December 2015, astructured questionnaire survey was conducted for infants and parents about the infants' oral hygiene product use from 0 to 4 years of age in Seoul and other metropolitan areas. Results: The use of oral tissues for infants and children was more frequent in infants, with less than four uses of oral tissues per 10 infants. The overall amount of toothpaste usage among infants was lower than those of infants whose parents are high school or college graduates. The number of oral tissues used per infant per week was less among infants who sucked less than 4 times per 10 infants. The frequency of use of infant mouthwash per week in every 10 infants was less than those who swallow mouthwash less than once. The number of mouth rinses after the use of oral tissues for infants was high in boys, and the number of infants who sucked oral tissues was less than 4 times when used 10 times. The number of mouth rinses after the use of toothpaste was less for infants with college-graduate parents. The factors affecting the number of mouth rinsings after using oral tissues for infants were gender and sucking frequency. Conclusions: In this study, the oral hygiene products for infants were found to differ and affect the usage, the frequency of use, and the number of mouth rinses according to the general characteristics of infants' and parents and the use of oral hygiene products.

  • Background: Third molar extraction is associated with considerable pain and discomfort, which is mostly managed with oral analgesic medication. We assessed the analgesic effect of benzydamine hydrochloride, a topical analgesic oral rinse, for controlling postoperative pain following third molar extraction. Methods: A randomized controlled trial was conducted in 40 patients divided into two groups, for extraction of fully erupted third molar. Groups A received benzydamine hydrochloride mouthwash and group B received normal saline gargle with oral ibuprofen and paracetamol. Oral ibuprofen and paracetamol was the rescue analgesic drug in group A. Patients were evaluated on the $3^{rd}$ and $7^{th}$ post-operative days (POD) for pain using the visual analogue score (VAS), trismus, total number of analgesics consumed, and satisfaction level of patients. Results: The VAS in groups A and B on POD3 and POD7 was $4.55{\pm}2.54$ and $3.95{\pm}1.8$, and $1.2{\pm}1.64$ and $0.95{\pm}1.14$, respectively and was statistically insignificant. The number of analgesics consumed in groups A and B on POD3 ($5.25{\pm}2.22$ and $6.05{\pm}2.43$) was not statistically different from that consumed on POD7 ($9.15{\pm}5.93$ and $10.65{\pm}6.46$). The p values for trismus on POD3 and POD7 were 0.609 and 0.490, respectively and those for patient satisfaction level on POD3 and POD7 were 0.283 and 0.217, respectively. Conclusions: Benzydamine hydrochloride oral rinses do not significantly reduce intake of oral analgesics and are inadequate for pain relief following mandibular third molar extraction.

  • 구취감소와 구강청결의 목적으로 사용되는 구강 양치액과 음용수로 사용되고 있는 알칼리 이온수를 대상자 49명에게 적용하여, 사용 전 후 구강 내 상주하는 세균에 미치는 영향을 비교 평가를 위해 세균배양 및 광학현미경 관찰을 통해 다음과 같은 결과를 얻었다. 1. 배양 후 확인된 구강 양치액 사용 전 후 세균 수는 Hexamedin 71.29%로 가장 큰 감소율을 보였고, 이어 Listerine 62.25%, Caregargle 42.26%, Garglin 33.52%, saline 21.62%, alkaline ionized water 16.08%, distilled water 7.67%의 순으로 나타났다. 2. Wilcoxon's signed rank 검정 결과, Hexamedin에서 사용 후 세균 수의 감소가 유의하게 나타났고(p<0.05), 그 외 구강 양치액에서는 통계적인 차이는 보이지 않았다(p>0.05). 3. 그람염색 후 광학현미경 관찰 결과, 구강 양치액 및 알칼리 이온수 사용 전에는 다수의 구균과 일부 실사균이 관찰되었으나, 사용 후에는 대부분 구균이 관찰되었고, 실사균은 거의 관찰되지 않았다. 4. 구강 양치액 및 알칼리 이온수의 pH 차이는 구강 내 세균 수 변화에 영향을 미치지 않았다. 본 결과를 종합하면, Hexamedine과 Listerine의 구강 내 세균 감소율이 각각 71.29%, 62.25%로 나타나 치과치료 전 적용 시 효과가 높음이 입증되었다. 그 외 구강 양치액과 알칼리 이온수는 구강 내 세균 감소효과가 낮은 것으로 나타났다. 그리고 세균 감소는 pH 보다는 구강 양치액에 포함된 항균 물질의 성분이 영향을 주는 것으로 생각된다.

  • Objectives: The purpose of this study was to verify the oral environmental change in using the natural oral cleaner containing propolis and prevention effect of oral disease. Methods: The subjects were 60 university students in Gangwon province. The groups consisted of 30 students of experimental group and 30 students of control group. The subjects were those who did not take the antipsychotic, diuretic, antihistamine, and anesthetic. The students rinsed their mouth with propolis mixture of oral cleanser for 4 weeks after receiving informed consent from October 1 to November 2, 2012. Collected saliva was measured for amount, salivary consistency, pH, plague index, gingival index, and halitosis. Results: The amount of salivary in propolis mixture of oral cleansing group remarkably increased (t=2.16, p<0.05). pH was alkaline in the group with oral cleaner containing the propolis (t=2.80, p<0.01). The bad breath remarkably decreased in the group with oral cleaner containing the propolis (t=-5.77, p<0.001). Conclusions: The use of the oral cleaner containing the propolis increased the amount of salivary and pH. The use of oral cleaner containing the propolis reduces halitosis and maintains good quality of oral hygiene.

  • Halitosis is mainly caused by the presence of volatile sulfur-containing compounds (VSC's) produced by proteolytic periodontopathic bacteria in the oral cavity. Various mouth-rinses have been offered on the market as solutions to reduce halitosis. The aim of this study was to find a potent substance for the prevention of halitosis. The halitosis prevention substance (HPS) from cumin seed powder was purified by solvent extraction, silica gel column chromatography and preparative TLC to yield an oil phase (0.98%). Instrumental analysis such as FT-IR, $^1H$-NMR and $^{13}C$-NMR showed that HPS contained an -OH group, -HC=CH-, -COO-, and long chain acyl group. HPS was therefore determined to be 2-hydroxyethyl-${\beta}$-undecenate. HPS inhibited the growth of Fusobacterium nucleatum and Porphyromonas gingivalis, by 72.44% and 64.37% at $1{\times}10^{-2}\;M$, and by 99.85% and 91.62% at $5\;{\times}\;10^{-2}\;M$, respectively. It also inhibited the activity of L-methionine-${\alpha}$-deamino-${\gamma}$-mercaptomethane-lyase (METase), which was produced by oral microbes. Furthermore, the VSC production by oral microbes in the human mouth air decreased with increasing HPS concentration. These results suggested that HPS from cumin seed is an efficient halitosis prevention agent.

  • Objectives: We analyzed the relative beneficial impacts of probiotics and coconut oil-based mouth rinses on oral health. Methods : A total of 33 subjects were enrolled and randomly assigned to three groups. Coconut oil and probiotics were given to the experimental group, and distilled water to the control group. We evaluated the possession site of Gingival index, CPITN index, BOP, Pocket depth, and PHP index. Results: In the coconut oil and probiotic groups, Gingival index significantly decreased on both days 15 and 30. CPITN significantly decreased on days 15 and 30 in the coconut oil group (p<0.01), and on day 30 in the probiotic group (p=0.002). There was a significant interaction between group and time for BOP and PHP index (p<0.001), and the coconut oil group was more effective in improving BOP and PHP index. Conclusions: The above results showed that the mediation effect of coconut oil and probiotics was more effective with coconut oil.
