This survey study was conducted on dental technician school students in April 2008 to investigate the effects of smoking on oral health. 110 male and 39 female students were surveyed and cross analysis was performed to examine the relationship between oral health status and smoking-related and oral health maintenance characteristics of smoking and non-smoking group. T-test and one-way ANAVA was used to analyze the average difference verification of two independent samples(smoking group and non-smoking group) and followings are the results. In general characteristics, 74 male students(74.7%) and 25 female(25.3%) students smoked and the percentage of male students were higher in smoking group. Regarding class grade, 2nd-year students(37 students, 37.4%) and 1st-year students(18 students, 36.0%) took the highest percentage of smoking and non-smoking group, respectively. Concerning the experience of drinking, smoking group consumed more alcoholic beverages(94 students, 94.9%) With respect to the frequency of between-meal consumption, respondents who eat between-meal once or twice smoked more. Respecting preferences of sweet food, respondents who enjoyed sweet food smoked more. Concerning smoking characteristics, many of smoking group had been smoked fo a long time(two to five years) and it was worrisome. About the amounts of smoking, 50 respondents(52.6%) of smoking group smoked 20 cigarettes a day with the highest proportion. With regard to the awareness of harmfulness, 70 respondents(70.7%) considered smoking as very harmful and showed that smoking group were aware of its harmfulness but it was habitualized. Respecting smokers in family members, father was more common as smokers(58 respondents, 58.6%) in family and showed that the influence of father. Main reasons of poor periodontal health were alchoholic consumption, smoking, and oral parafunctional habit(57 respondents, 56.7%) in smoking group and neglect of oral hygiene(21 respondents, 42.0%) in non-smoking group. With regard to the scaling, 80 respondents of smoking group(80.8%) didn't received scaling and showed that more oral health education was required. Regarding the periodontal status, non-smoking group was $1.26{\pm}0.44$, respondents who received scaling was $1.43{\pm}0.50$, respondents who regularly floss was $1.50{\pm}0.52$, respondents who brush more than three times a day was $1.38{\pm}0.49$ and had better periodontal health. Bleeding during tooth brushing was more frequent in smoking group ($1.51{\pm}0.70$). Regarding mouth order, non-smoking group was $2.34{\pm}0.62$, after scaling was $2.02{\pm}0.76$, patients who regularly floss was $1.50{\pm}0.52$, patients who brush more than three times a day was $1.81{\pm}0.87$. Concerning the experience of dental caries treatment, smoking group was $1.20{\pm}0.40$, patients who do not floss was $1.30{\pm}0.46$, patients who brush once a day was $1.29{\pm}0.45$. With regard to dental prosthesis, non-smoking group was $3.78{\pm}1.62$, patients who received scaling was $1.43{\pm}0.50$, patients who regularly floss was $1.40{\pm}0.51$, patients who brush more than three times a day was $1.24{\pm}0.43$. From these results, oral health education and smoking has correlation and more oral health education needs to be carried out to educate students with non-health related majors about harmfulness of smoking on oral health. Also more study are required.

The purpose of this study was to investigate the relationship between the teeth and Zhang-Fu(臟腑), dental diseases, and the hygiene of the mouth through the literature of oriental medicine. First, the relatonship between the teeth and Zhang-Fu is reviewed as follows: The teeth are influenced by Shen(腎) because they are the end of bone and Biao(標) of Shen. Gingiva is related to Wei(胃) and Da-Chang(大腸) because it is passed by Yangming-Channel(陽明經). The growth and nutrition of teeth depends on Shen. The pathological condition of Shen causes the gingival atrophy, the loose of teeth, dedentition due to aging, withering of teeth, and tartar: whereas the pathological condition of Wei and Da-Chang causes toothache, gingivitis, inflamed gums, bad breath, and gingival hemorrhage. Second, the causes and therapies of dental diseases through the literature can be summarized as follows: The major causes of toothache are the pathogenic condition of wind-heat and wind-cold, the heat syndrome of Wei, the damp-heat of intestine, flaring-up of fire of deficiency type, rotten tooth, etc... The principal causes of dedentition and the shaking and loose of teeth are the deficiency of Shen, and the rest of causes are the damp-heat of Yangming. Gingival atrophy is caused by the deficiency of Shen, whereas the gingival hemorrhage comes from the factors in the pathogenic factor of wind-heat of Yangming-Channel, the heat syndrome of stomach, and the deficiency of Shen. The causes of grinding of teeth during sleeping are stomach-heat, and the delayed dentition and the withering result from the deficiency of Shen-Jing.(腎精) The principal therapies of toothache are removing wind and heat, clearing away heat and prompting diuresis, clearing away the stomach-heat, replenishing vital essence to tonify the Shen, relieving superficial syndrome by wind-cold, and alleviating pain by destroying parasites. For the prescription of the principal therapies, there are Xijio Dihuang Tang, Jiajian Ganlu Yin, Qufeng Wan, Qingwei San, Tiaowei Chenggi Tang Shengong Wan, Liangge San Qingwei Tang Yunu Jian, Liuwei Dihuang Wan Zuogui Yin Bawei Wan Wanshao Dan, Xixin San Badou Wan Gianghuo Fuzi Tang, Jiuzi Tang Badou Wan, etc... The therapies of dedentition and the shaking and loose of teeth are replenishing vital essence to tonify the Shen, and warming and recuperating the Shen-Yang: as the prescription, there are Liuwei Dihuang Wana Zuogui Yin, and Bawei Wan Anshen Wan Wanshao Dan Yougui Wan etc... The therapies of gingival hemorrhage are clearing away the stomach-heat, replenishing vital essence to tonify the Shen, warming and recuperating the Shen-Yang(腎陽), and moisturing and purging intence heat with the prescription of Tiaowei Chenggi Tang Xijiao Dihuang Tang, Liuwei Dihuang Wan Zuogui Yin, Bawei Wan Anshen Wan, and Yunu Jian. The therapy of gingival atrophy is replenishing vital essence to tonify the Shen in the prescription of Liuwei Wan Bawei Wan Ziyin Dabu Wan. The therapies of grinding of teeth during sleeping are clearing away the stomach-heat and purging intense heat, and invigorating the spleen through eliminating dampness in the prescription of Qingwei San, Wumei Wan, etc... The therapy of delaed dentition is replenishing vital essence to tonify the Shen with the prescription of Liuwei Wan Buyin Jian, etc... Third, clinical treatment reports of dental diseases are reviewed as follows: The toothache due to stomach-heat was treated by medical herbs like Gypsum, Natrir Sulfas, Rehmanniae, Schizonepetal Herba, Menthae Folium, Cimicifugae Rhizoma, and Scrophulariae Radix. The therapies of toothache due to flaring-up of fire in deficiency type from deficiency of Shen provided with replenishment of vital essence to tonify the Shen and clean ministerial fire, and the prescription was the kind of Liuwei Wan, which worked very well. The therapy of dedentition and loose of teeth due to deficiency of Shen was done to stablize the teeth as tonifing the Shen with the prescription of Guchi Wan. The rate of imrovement was over 90%. The destruction of periodontal tissue due to periodonititis was cured of dispelling wind, reducing heat, and alleviating pain, It was improved by taking Zizhi Xingiong Tang, Guchi Xiaotong San, Yunii Jian, and Qingwei San about 3-7 days, and the rate of improvement was over 80%. Fourth, the prevention and regimens are reviewed as follows: As a physical and breathing exercise of the teeth, tapping teeth which stimulates the circulation of Qi(氣) and Xue(血) had been used. The tapping time of 14, 17, 36, etc... has been reported, and it should be applied based on the body condition. The medical herbs for gargling and brushing teeth have been used. Specifically, Cimicifugae Rhizoma, Gypsum, Gypsum Fibrosum, and Indigo pulrelrata Lereis have been used to reduce heat, Coptidis Rhizama and Yang Jinggu to eliminate damp-heat, Amomi Semen, Cyperi Rhizoma, Flos Caryophylli, Asari Radix, Piperis Longi Fructus, Santali Albae Lignum, Meliae Fructus, Moschus, Aquillaiae Lignum, and Borneol to promote the circulation of Qi and to relieve pain, Ligustici Radix, Angelice Radix, Rhizoma Nardostachydis, Tribuli Semen to relieve superficial syndrome by means of diaphiresis, and Cnidii Rhizoma, Angelicae sinensis Radix, and Olibanum to promote blood circulation to stop pain.

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.
