曺圭澄 慶北大學校 醫科大學 1978 慶北醫大誌 Vol.19 No.2

最近 著者는 14才의 韓國人 男性의 上顎 左側 側切齒에서 稀有한 齒牙形態 異常의 一例를 觀察한 바 그의 肉眼的인 所見을 다음과 같이 要約한다. 1. 正常的인 上顎 側切齒보다 齒冠의 길이가 짧고 唇面에서 볼 때 上顎 犬齒의 唇面과 外形이 類似하며, 舌面에서 볼 때는 上顎 第一小臼齒의 咬合面의 外形처럼 다소 둥근 六角形을 하고 있다. 2. 이 齒牙는 正常的인 上顎 側切齒에서는 있어야 할 舌側窩와 Cingulum이 없고, 咬合面 中央에 異常發育의 咬頭가 突出하여 그 發育隆起 兩側으로 小形의 近心窩 및 遠心窩를 가지고 있다. 3. X-線像에서는 齒髓腔은 正常的인 形態를 갖고 있다. 4. 本 症例의 境遇처럼 形態異常의 齒牙 또는 過剩頭는 發育의 異常 또는 齒胚의 過剩形成에 起因된다고 思料된다. The author observed a rate case of a nomaly in the form of upper left lateral incior from 14 years old Korean male. The characteristics were as follows. 1. The tooth had shorter crown, cervico-occlusally when compared with normal maxillary lateral incisor. The crown morphology of th tooth had resemblance to labial aspect of maillary canine in labial view and to occlusal outline form of rounded hexagonal figure of the maxillary first premolar on the occlusal surface. 2. Unlike normal upper lateral incisor, there were not lingual fossa and cingulum from lingual aspect. The tooth had exaggerated cusp, mesiobuccal fossa and distobuccal fossa on the occlusal surface. 3. In the X-ray picture, there was a common pulp cavity. 4. Maxillary lateral incisors vary in form more than any other tooth in the mouth except the third molar. If the variation is too great, it is considered a developmental anomaly.

曺圭澄 慶北大學校 1984 論文集 Vol.37 No.-

The author had epidemiologically studied and evaluated the dental caries experience rate in the deciduous and permanent teeth of 2,835 Korean elementary school children aged from six to thirteen years residing at the out-lying island village. The obtained results were as follows: 1. The dental caries experience rate in the deciduous & permanent teeth of Korean elementary school children was 74.46% at the average of both sex, 73.51% at the age of six years, 74.48% at the age of seven years, 69.65% and 70.19% at the age of eleven and tweleve years, and so was over 73.51%. 2. The average number of caries experience teeth per mouth was 3.15 at total age, 4.17 at the age of six years, 4.43 and 3.61 at the age of seven and eight years, 3.18 and 2.48 at the age of nine and ten years, 1.90 and 1.29 at the age of eleven and tweleve years, and so was apt to decrease with aging. 3. Decayed teeth rate was 97.76% and 96.84% at the age of six and seven years, 98.97% and 99.08% at the age of eight and nine years, 97.03% and 97.58% at the age of eleven and twelve years, and 97.94% at the overall age. The author could find that the supply of dental treatment cares were urgent. 4. Filled teeth rate was 2.24%, 0.90% at the age of six, seven and eight years of both sex, 1.00%, 0.74% and 0.50% at the age of ten, eleven and twelve years, and 1.11% at the overall age, and so the another could find that valid dental treatment cares were few supplied. 5. There was non greatly different between male and female in the dental caries experience rate, the average number of caries experience teeth per mouth, decayed teeth rate and filled teeth rate all over the age.

曺圭澄 慶北大學校 醫科大學 1980 慶北醫大誌 Vol.21 No.2

齒牙健康度란 齒牙機轉의 生物學的 單位로써, 第一大臼齒의 機能에 對한 能力이며, 우식, 喪失 또는 充塡處置에 依하여 滅少되고, DMF指數는 齒牙健康度와 最大의 齒牙健康度와의 差異點을 나타낸다. 署者는 僻地인 山間地域에 居住하는 7才부터 12才까지의 男女學童 1953名을 對象으로 第一犬臼齒의 齒牙健康度 및 DMF指數를 著査한 바 다음과 같은 結果를 얻었다. 1. 山間地域學童 第一大臼齒의 齒牙健康度는 男女 平均하여 7才에서 97.13, 8才에서 95.48, 9才에서 95.23이며 11才 및 12才에서는 93.70 및 92.60으로서, 年齡이 增加함에 따라 減少되어 나타났고, 反對로 DMF指數는 增加되어 나타났다. 2. 全體年齡에서 第一大臼齒의 DMF指數는 男子에서 4.15 및 女子에서 6.25이며 全體年齡에 걸쳐서 犬體로 女子가 男子보다 多少 높았다. 3. 一人當 保有하고 있는 第一大臼齒의 DMF齒牙數는 年齡의 增加에 따라 大體로 增加되어 나타났고, 男女 全體年齡에서 1.02個로서 山間地域 學童의 成長期의 齒牙健康을 爲하여 齒科醫療의 供給이 時急히 必要함을 알 수 있다. Dental health capacity is defined as the capability of the first permanent molars to function as a biologic unit of the dental mechanism and the DMF index represents the difference between the dental health capacity and maximum dental health capacity. The author had epidemiologically studied on the dental health capacity and the DMF index of first permanent molars of 1953 Korean school children at the age from seven to twelve years residing in the mountain village. The obtained results were as follows; 1. Dental health capaclty of first permanent molar of children at the both sex was 97.13 at the age of seven years, 95.48 at the age of eight years, 95.23 at the age of nine years, and 93.70 and 92.60 at the age of eleven and twelve years, and so decreased with aging, but DMF index showed increased. 2. DMF index at the total age of first permanent molar was 4.15 at male and 6.25 at female, all through the ages female was slightly higher than male. 3. The average number of DMF teeth of first permanent molar was increased with aging and was 1.02 at the total age. The author could find that Korean school children residing in mountain village need urgently the dental treatment care for their improvement in dental health.

韓國學童의 地域別 齒牙우식증 經驗度(Ⅰ) : 山間地域 Dental Caries Experience Rate of Children in Mountain Village

曺圭澄 慶北大學校 醫科大學 1980 慶北醫大誌 Vol.21 No.1

우리나라에서 齒牙缺損의 가장 큰 原因疾患中의 하나인 치아우식증의 發生에 自然的 社會的 條件이 미치는 影響을 두명하기 위하여, 著者는 文明의 惠澤이 比較的 덜 미치는 僻地인 山間地域에 居住하는 7才부터 12才까지의 男女 學童 1265名을 對象으로, 世界保健機構에서 勸奬하는 基準에 따라 乳齒 永久齒를 包含하여 치아우식 經驗率을 調査硏究한바 다음과 같은 結果를 얻었다. 1. 山間地域 學童의 乳齒 永久齒에서 치아우식 經驗率은 7才에서 72.44%, 10才에서 73.02%, 12才에서 71.07%로서 치아우식 經驗率은 72.44% 以上이었다. 2. 全體 年齡에서 치아우식 經驗率은 74.62%이며, 男子 73.83%, 女子 75.44%로서 男子보다 女子에게서 多少 높았으나 크게 大差는 없었다. 3. 1人當 平均 우식경험치아의 保有數는 全體 年齡에서 3.61個이며, 7才에서 4.24個, 9才에서 3.74個, 12才에서 2.79個로서 齒牙 交換機에서는 年齡增加에 따라서 多少 減少 되어 나타났다. 4. 우식치률은 7才, 8才, 12才 및 全體 年齡에서 100.00%, 99.89%, 98.87% 및 99.23%로서 매우 높고, 處置置率은 7才, 8才, 12才 및 全體 年齡에서 0.00%, 0.11%, 1.14% 및 0.33%로 매우 낮아, 山間地域 學童의 치아우식에 對한 齒科醫療는 거의 供給되고 있지 않았음을 알 수 있었다. In order to reserch on dental caries incidence socia-geographically, the author had epidemiologically studied the dental caries experience rate in the deciduous and permanent teeth of Korean children residing in the mountain village, in the 1,265 school boys and girls at the age from seven to twelve years. The obtained results were as follows; 1. The dental caries experience rate in the deciduous and permanent teeth of Korean children residing in mountain village was 72.44% at the age of seven years, 73.02% at the age of ten years and 71.07% at the age of twelve years, and so was over 72.44%. 2. The overall dental caries experiance rate in the deciduous and permanent teeth was 73.83% at male, 75.44% at female and 74.62% at the average of both, higher at female than that at male, however, the both sex was not greatly different in general. 3. The average number of caries experience teeth per mouth of Korean children residing in mountain village was 3.61 at total age, 4.24 at the age of seven years. 4.74 at the age of nine years and 2.79 at the age of twelve years, and so was apt to decrease with aging within mixed dentition period. 4. Decayed teeth rate was 100.00% at the age of seven years, 99.89% at the age of eight years, 98.87% at the age of twelve years and 99.23% at the total age, and filled teeth rate was 0.00% at the age of seven years, 0.11% at the age of eight years, 1.14% at the age of twelve years and 0.33% at the total age, and so the author could find that few dental treatment cares for dental caries on the deciduous and permanent teeth of Korean children residing in mountain village were supplied.

The purpose of this study was to investigate the pulpal responses of dental adhesive resins. A total of 40 cavities of the permanent healthy teeth from 4 dogs were prepared. In the experimental group, the cavities were etched for 1 minute with citric acid and filled with experimental resins (ie. Super-Bond C & B^ⓡ). In the control group, the cavities were filled with calcium hydroxide base materials (ie. Dycal^ⓡ) without etching. The dogs were sacrificed at one, two, three and four weeks after the time of filling and the specimens were routinely prepared and stained with Hematoxylin-Eosin. The microscopic findings were as follows: Infiltration of inflammatory cells was not observed in both experimental and control groups. Change in the odontoblastic layer was not observed in all control groups but severe swelling was observed in deep dental pulp tissue of the control two and three week cases. Pulp tissue was recovered with plenty of fibrous component in the control four week case and reparative dentin formation was not occurred in all cases. Slight changes of the odontoblastic layer beneath the cavity were observed in the experimental one week case. In experimental two and three week cases, swelling of deep pulp tissue was increased and localized reparative dentin formation was observed. In the experimental four week case, odontoblastic layer was recovered with regular appearance and fibrous component of the pulp was increased, but reparative dentin formation was not evident.

曺圭澄 慶北大學校 齒科大學 1986 慶北齒大論文集 Vol.3 No.1

著者는 國民口腔保健의 增進을 爲해서는 初期學童들에 對한 口腔保健管理가 效率的인 한 方法일 것으로 判斷하여, 이에 對한 地域社會의 再認識이 時急함을 疫學的으로 調査, 提示할 目的으로, 社會的, 經濟的 與件이 比較的 良好하다고 할 수 있는 大邱直轄市 都心部의 " S ", " J " 國民學校 學童 男子 852名, 女子 747名, 都合 1,599名을 對象으로 世界保健機構에서 勸奬하는 基準에 따라 乳齒 및 永久齒의 우식경험율을 調査하고, 우식경험치아에 對한 우식치아의 百分率인 우식치율을 算出한 바 다음과 같은 結果를 얻었다. 1. 都市地域 學童의 우식 乳齒率은 6才부터 12세才까지의 全體 年齡層에서 男子 平均 75.25%, 女子 平均 77.78%였으며, 男女 總合의 平均値는 76.39%였다. 2. 우식 永久齒率은 全體 年齡層에서 男子 平均 68.77%, 女子 平均 75.82%로 男子보다 女子에서 多少 높게 나타났으며, 男女 總合의 平均値는 72.23%였다. 3. 都市地域 學童의 우식치율은 男子 平均 73.33%, 女子 平均 77.24%이며, 全體 平均値는 75.25%로 나타나 乳齒, 永久齒를 莫論하여 約 75%로 以上의 우식이충치아가 齒料醫療의 未需給 狀態인 것으로 드러나, 學校口腔保健事業의 根本的 對策樹立과 그 實施가 時急함을 알 수 있었다. It has been widely known that the dental health care of primary school children is one of efficient ways for improving the degree of oral health. So it seemed to be worth that the proportion of teeth with untreated caries to caries experienced teeth was evaluated to appreciate the direction for improving the dental health of school children. The author had epidemiologically studied and evaluated the decayed teeth rates in deciduous and permanent dentition of 1599 Korean primary school children aged from six to twelve years residing in Taegu city area. The obtained results were as follows ; 1. The decayed teeth rate in the deciduous teeth of Korean school children of urban area was 75.05% at male, 77.78% at female and 76.39% at the average of both. 2. The decayed teeth rate in the permanent teeth was 68.77% at male, 77.24% at female and 72.23% at the average of both, it showed some difference of decayed teeth rate in the permanent teeth between male and female. 3. The overall decayed teeth rate in the deciduous and permanent teeth was 73.33% at male, 77.24% at female and 75.25% at the average of both, so the number of more than 75% of caries experienced teeth was untreated and remained in oral cavity of primary school children of urban area as conditions involved with caries. At the point of view, special consideration must be paid to programs of the dental health education in school, and more intensive ways of the oral health care than now is needed.
