본 논문은 SLS의 함유정도를 다르게 한 A(0%), B(1.1%), C(2.2%)의 세가지 실험세치제를 제작하여 구강 내 변화를 50명씩 세 그룹(A, B, C)으로 나누어 실험하였다 본 연구결과 SLS함량에 따른 세치제의 4주간 사용 후 3집단의 치면세균막 검사( PHP )에서 집단간차이가 나타났고 SLS함량이 높을수록 PHP의 지수가 낮아졌다. 또한 간이구강위생지수(OHI-S)에서는 A, B, C 세집단 모두에서 OHI-S 값이 줄었다. 또한 PHP와 OHI-S는 높은 상관성을 보였다. SLS함량에 따른 세치제의 4주간사용 후 3집단의 타액분비량 측정 시 SLS함량이 높아질수록 타액량이 감소하였고, 타액의 점조도 및 pH에는 변화가 없었다. SLS가 구강건조를 유발함을 뒷받침하는 결과로 SLS와 타액의 분비량은 음의 상관관계를 보였다.

Objectives : This study evaluated the changes in surface roughness of denture base resin according to the types of denture cleansers. Methods : A denture base resin(Vertex RS, Dentimax, Netherland) was used. Two toothpaste(Antiplaque, Bukwang, Korea; 2080, Aekyung, Korea) and a kitchen detergent(Trio, Aekyung, Korea) were used as a denture cleanser. The specimens were put on the V8 crossbrushing machine(Sabri enterprises, Downers grove, IL, USA) to reproduce toothbrushing and the toothbrushes were flat, round end and soft type. The surfaces of denture base resin specimens were observed by profilometer(SJ-400, MITUTOYO, Japan) and SEM(S-3000N, Hitachi Co., Ibaraki, Japan). Results : 1. According to the result of measuring surface roughness, there was statistically significant difference in Ra, Rq, and Rz(p<0.05). 2. As for Ra, Rq and Rz, Antiplaque toothpaste showed the highest roughness, and there was significant difference from other groups(p<0.01). 2080 toothpaste, Trio, and distilled water were classified as the same group. 3. According to the result of observation with the SEM, the surfaces of the Antiplaque toothpaste group after toothbrushing showed the greatest roughness, and the surfaces of 2080 toothpaste, Trio, and distilled water groups were rough in order. Trio and distilled water had the surfaces similar to those before toothbrushing. Conclusions : Studies to compare the efficacy of denture management methods and examine the effects of denture cleansers on denture materials will be helpful for dental hygienists and dentists providing patients with proper information and education. And it will be also useful for denture users' oral health.

Objectives : The purpose of this study was to evaluate the tooth whitening effect of 0.74% and 2.80% hydrogen peroxide toothpastes and safety on tooth and gingival tissue. Methods : Toothpastes containing 0.74% and 2.80% hydrogen peroxide were evaluated. In in-vitro test, some additives (sodium metaphosphate, sodium pyrophosphate and titanium dioxide) were added to the toothpastes. Hydroxyapatite specimens (HAPs) were made and stained using modified Stookey's methods. HAPs were treated for 1 hour at shaking incubator and brushed for 1,000 times as 250 gF with each diluted toothpaste. Before and after color was measured by colorimeter. Using double blind method, 99 Korean with natural maxillary anterior teeth were selected and the initial brightness (baseline) was measured by SHADEEYE-EX. Based on this measurement they were crossly distributed into control group (0% hydrogen peroxide), test 1 (0.74% hydrogen peroxide) and test 2 (2.80% hydrogen peroxide). After 2 weeks, people of each group were provided toothpaste and told to use 3 times a day right after every meal for 3 minutes. The brightness of teeth was measured 3 times for every one month. Results : ${\Delta}L$ was statistically significant among three groups in shaking test. ${\Delta}L$ of two test groups was statistically significant compared with control group but not between each test group in brushing test. After using toothpaste for 3 months, test 1 group and test 2 group were 15.89% and 31.23% more whitened compared with control group respectively (p<0.05). Rate of more whitened person of each test group was 24.2% and 40.5% more than control group respectively (p<0.05). There was no difference in the hypersensitivity during 3 months using toothpastes and no side effect on teeth or gums. Conclusions : Toothpastes containing 0.74% and 2.80% hydrogen peroxide showed tooth whitening effect and both were safe enough to use for tooth whitening.

Background: The purpose of this study is to investigate the tooth whitening effect of Listerine Healthy White and provide effective management of extrinsic discoloration by comparing the whitening effects of existing whitening products. Methods: The included study four groups: those using whitening gel, whitening toothpaste, and Listerine Healthy White and a control using artificial saliva. Each group received 40 bovine tooth specimens, which were stained with commonly consumed tooth-coloring-inducing foods; black tea, black coffee, and instant noodles for 72 hours. The specimens were treated with tooth whitening materials for 5 weeks, after which the lightness (L^*) was measured weekly using a spectrophotometer. Results: There was a significant difference in lightness among the groups between the 1st and 5th week of treatment for all tooth-coloring-inducing foods (p<0.05). When comparing the changes in lightness values from before whitening to the 5th week of whitening for all tooth-coloring-inducing foods, the order of change was as follows: whitening gel, whitening toothpaste, Listerine Healthy White, and artificial saliva. Listerine Healthy White showed a significant whitening effect for all tooth-coloring-inducing foods (p<0.05). Particularly, changes in lightness values for specimens stained by black tea after 5 weeks of whitening were in the following order: whitening gel (21.72), whitening toothpaste (14.89), Listerine Healthy White (12.91), and artificial saliva (3.85). For specimens stained by black coffee, the changes in lightness values were in the following order: whitening gel (12.99), whitening toothpaste (9.66), Listerine Healthy White (7.91), and artificial saliva (3.12). Lastly, changes in lightness values for specimens stained by instant noodles were as follows: whitening gel (10.84), whitening toothpaste (9.85), Listerine Healthy White (7.71), and artificial saliva (2.61). Conclusion: Listerine Healthy White exhibits continuous whitening effects over time, and for consumers seeking convenient ways to achieve tooth whitening effects at home, consistent use of Listerine Healthy White is recommended.

Many researches are being done to study the effect of toothpaste containing natural extracts. The aim of this study was to evaluate the plaque control effect and therapeutic effect of toothpaste products containing chitosan extract. 120 healthy subjects with gingivitis or early periodontitis were divided into two groups. Subjects in the experimental group only used toothpaste containing chitosan and subjects in the control group used toothpaste without chitosan. At first, subjects received scaling and tooth brushing instruction. Gingival index, bleeding index, probing pocket depth, probing attachment level were scored at baseline, 2 months, and 3 months, and plaque index were scored at baseline, 1 month, 2 months, 3 months. Gingival index of experimental group and control group at baseline, 2 months, and 3 months use were 0.71${\pm}$0.66, 0.49${\pm}$0.55, 0.36${\pm}$0.49 and 0.62${\pm}$0.58, 0.51${\pm}$0.52, 0.48${\pm}$0.50 (mean${\pm}$SD), respectively (statistically significant different at p <0.05 ). Plaque index of experimental group and control group at baseline, 1 month, 2 months, and 3 months were 0.52${\pm}$0.50, 0.43${\pm}$0.50, 0.39${\pm}$0.49, 0.29${\pm}$0.46 and 0.49${\pm}$0.50, 0.50${\pm}$0.50, 0.51${\pm}$0.50, 0.45${\pm}$0.50, respectively (statistically significant different at p<0.05 ). Bleeding index of experimental group and control group were 0.40${\pm}$0.49, 0.33${\pm}$0.47, 0.24${\pm}$0.43 and 0.40${\pm}$0.49,0,38${\pm}$0.49,0.30${\pm}$0.46, respectively (statistically significant different at p<0.05). Probing depth of experimental group and control group were 2.41${\pm}$0.64, 2.31${\pm}$0.60, 2.28${\pm}$0.55 and 2.51${\pm}$0.67, 2.47${\pm}$0.63,2.42${\pm}$0.62, respectively (statistically significant different at p${\pm}$0.66, 2.32${\pm}$0.62 and 2.54${\pm}$0.70, 2.51${\pm}$0.69,2.46${\pm}$0.66, respectively (statistically significant different at p<0.05 ). From these finding, it can be concluded that toothpaste containing chitosan have better plaque control effect and therapeutic effect on gingivitis and early periodontitis compared to conventional toothpastes.

Dental abrasive, dicalcium phosphate dehydrate (DCPD) was prepared and the several important factors affecting on the quality of toothpaste were investigated by means of set test, glycerine absorption, Coulter counter test, color difference, BET adsorption, mercury porosimetery, and rheogram comparing with two foreign DCPDs, MFO4 and Dentphos K. Sample DCPD was prepared by reaction between 85% H$_{3}$PO$_{4}$ and 15% milk of lime at $39^{\circ}C$ (pH6.5), and stabilized with TSPP and TMP. The physicochemical properties of Sample DCPD were obtained as follows: whiteness (98.99), average particle size (15.5 $\mu\textrm{m}$), pH (7.9), remainder particle weight (0.49w/w%), glycerine absorption value (64 ml), and set test (passed). N$_{2}$ adsorption curves (BET) of three kinds of DCPD showed non-porous type III isotherm. BET adsorption parameters of sample DCPD showed that surface area was 24.9 m$^{2}$/g, total pore volume 0.09 cm$^{3}$/g and average pore radius 72.0 $\AA$. The rheogram of the toothpaste containing each DCPD showed bulged plastic flow with yield vlaue and thixotropic behavior. These results meet standard requirements as abrasive standard, and suggested that synthesized sample DCPD could be used a dental abrasive such as a high quality grade in practice as foreign DCPDs.

이 논문의 목적은 청소년 교정환자들의 치은염과 치아탈회를 조절하기위해 사용된 수종의 화학요법들에 관해 최근에 보고된 2개의 연구를 재검토하기 위함이다. 첫번째 연구(치은염 연구)는 고정성 교정장치를 장착하고 있는 경우, 기존의 칫솔법에 매일 2회 유효 주석 이온이 $90\%$이상 함유된 $0.4\%$의 겔형 불화주석($SnF_2$ gel)을 함께 사용하는 경우와 기존의 칫솔법만을 사용하는 것 중 치태침착과 치은염을 조절하는데 있어서 어느 것이 더 효과적인지를 결정하기 위하여 시행 되었다. 두번째 연구(치아탈회 연구)는 교정환자들을 대상으로 II00ppm의 불소가 함유된 치약만을 사용할 때와 이와 똑같은 치약과 $0.05\%$ 불화나트륨 양치액(NaF rinse)을 병용하여 양치하거나 이 치 약과 함께 $0.4\%$ 겔형의 불화주석을 사용할 때 치아탈회의 조절효과를 비교하기 위하여 시행 되었다. 치은염 연구에서는 모든 치아를 고정성 장치로 계속 치료를 받고 있는 청소년 교정환자 65명을 연령과 성별에 따라 두 군으로 지정하였다. 마찬가지로 치아탈회 연구에서도 30명을 추가(총 95명)하여 제 3군으로 지정하였다. 제1군(대조군, 35명)은 단지 표준화 불소(1100 ppm 불소) 치약만 사용하였다. 제 2군은 1 군과 같은 치약에 겔형의 $0.4\%$ 불화주석이 함유된 치약을(겔형 불화주석군, 표본수=30) 매일 2회씩 18개월 동안 사용하였다. 제 3군은(단지 치아탈회군만으로 이용) 같은 종류의 치약과 $0.05\%$ 불화나트륨 양치액을 사용하였다(불화나트륨 양치군, 표본수=30). 치태침착의 임상평가는 Plaque Index로, 치은의 염증은 Gingival Index로, 치관의 착색은 단일맹검(single-blind)으로, 고정성 교정장치를 장착하기 전과 장착한 후 1, 3, 6, 9, 12, 18 개월마다 실시하였다. 치아탈회의 임상평가는 맹출한 모든치아의 순측면에 고정성 교정장치를 장착하기 전과 장치 제거 3개월 후에 단일맹검으로 실시하였다. 치은염 연구에서 겔형 불화주석군($SnF_2$ gel group)이 대조군에 비해 교정치료 기간동안 시행한 모든 검사에서 Plaque Index(p<0.01)와 Gingival Index(p<0.001)가 상당히 낮은것으로 나타났다. 겔형 불화주석군에서 한 증례는 미미한 치관착색을, 두 증례는 보통정도의 치관착색을 보였다. 치아탈회 연구에서는 겔형 불화주석군과 불화나트륨 양치액군이 치료후 치아탈회값에서 치료전 치아탈회값을 뺀 치아탈회값이 대조군에 비해 구강전체및 제1대구치에서 현저하게 낮은 값(p<0.05)을 보였다. 비록 겔형 불화주석군이 불화나트륨 양치액군보다 일관되게 낮은 치아탈회값을 보였을지라도 통계적으로 그 차이는 단지 유의성을 보이는 정도였다.
