치근천공은 근관치료시 종종 발생되는 사고로서 치근과 치주조직과의 개통을 의미하며, 치과의사에 의하여 우발적 또는 의도적으로 발생된다. 성공적인 치근천공의 치료로서 즉시 천공부위를 충전하여 감염을 방지하는 것이 중요한데 이러한 목표를 위하여 치근천공의 발생 시간, 크기 및 위치에 대한 고려가 필요하다. 치근천공의 진단을 위하여 직접 육안으로 출혈을 관찰하거나 방사선검사 또는 천공위치를 파악하는 보조적 방법 등이 유용하며, 치료로서 비수술적 또는 수술적 방법이 사용될 수 있다. 본 증례는 전북대학교 소아치과에 내원한 환자에서 영구전치의 치근 치경부에서 치근 천공이 일어난 경우로서 보존적인 접근을 통해 양호한 결과를 얻었기에 보고하는 바이다. Root perforations that result in a communication of the root space with the periodontal tissues occasionally occur during endodontic procedures. They may be induced iatrogenically. Successful treatment depends mainly on immediate sealing of the perforation and prevention of infection. Several factors affect the achievement of these goals, most important of which are time of occurrence, size and location of the perforation. Identification of root perforations is possible by direct observation of bleeding, radiography and an apex locator. Perforation defects may be repaired by nonsurgical or surgical techniques. We report two cases of root perforation. One was treated by glass ionomer, other was treated by composite resin with calcium hydroxide.

백병주,김미라,김재곤,양연미,Baik, Byeong-Ju,Kim, Mi-Ra,Kim, Jae-Gon,Yang, Yun-Mi 대한소아치과학회 2002 大韓小兒齒科學會誌 Vol.29 No.3

본 연구는 한국인의 유치열기 아동, 영구치열기의 구개의 폭, 길이, 구개의 용적, 구개 용적과 구개면적의 상관관계 등을 조사하여 남녀간의 차이, 유치열과 영구치열과의 변화 정도를 파악하고 다양한 구개의 연구를 할 수 있는 기초자료로 삼고자 하였다. 연구대상으로 정상교합의 유치열기 아동(Hellman dental age II A) 100명(남자 50명, 여자 50명)과 영구치열기의 성인(Hellman dental age IV A) 86명(남자 43명, 여자 43명), 총 186명을 대상으로 하여 제작한 상악의 석고모형을 이용하였다. 3차원 laser scanner(DS4060, LDI, U.S.A.), cloud data를 이용하여, polygonization, section curve와 loft surface, 표준평면, 수직평면 등을 얻은 후에 구개용적, 구개의 폭, 구개의 길이 등을 측정하였다(Surfacer 10.0, Imageware, U.S.A). 상수의 결정을 위해 유치열, 영구치열을 남녀별로 구분하여 결과를 구하였으며 남녀간의 차이는 student t-test를 이용하여 검정하여 다음과 같은 결론을 얻었다. 1. 표준평면과 각 치아, 치아 및 구개사이의 측정점들간의 거리는 영구치열에서 더 멀었다. 2. 영구치열에서의 구개용적이 유치열에서 보다 3배이상 컸으며 특히 영구치열에서는 여자에 비해 남자에서 유의성 있게 크게 측정되었다(p<0.05). 3. 구개폭은 유치열과 영구치열에서 남자에서 유의성 있게 크게 나타났지만 구개길이는 영구치열에서만 유의성 있게 컸다(p<0.05). 4. 유치열과 영구치열, 남자와 여자 모두에서 후구개폭과 총구개길이가 이루는 면적 이 구개용적과 가장 큰 상관관계를 보여주었다(r=0.401, r=0.450, r=0.678, r=0.654). The purpose of this study was to clarify the palatal arch length, width and volume in the primary and permanent dentition. Samples were consisted of normal occlusion in the primary dentition(50 males and 50 females) and permanent dentition(43 males and 43 females). Their upper plaster casts were used and through 3-dimensional laser scanning(3D Scanner, DS4060, LDI, U.S.A.), cloud data, polygonization, section curve, loft surface and fit and horizontal plane were made for measuring the palatal arch length, width and volume(Surfacer 10.0, Imageware, U.S.A.). Correlation coefficients were calculated separately for males and females in each group(SPSS 10.0). The results were as follows : 1. Average distance from the fit plane to the points(tooth-tooth-palate) was greater in the permanent dentition than those of primary dentition. 2. Palatal volume was greater more than 3 times in the permanent dentition, especially it was greater in male compared to female with significance(p<0.05). 3. Palatal width of male was greater in the primary and permanent dentition but palatal length, only in the permanent dentition than that of female(P<0.05). 4. Correlation coefficients were statistically most significant between the palatal volume and size of posterior palatal width and total palatal length(r=0.401, r=0.450, r=0.678, r=0.654).

The odontomas are most common odontogenic tumors composed of various tooth-like structures : enamel, dentin, cementum, pulp tissue. The etioglogy of the odontoma is not evident but it has been suggested that local trauma or infection may produced such a lesion. Clinically, they are asymptomatic, slow growing and lesions of limited growth that show no infitration to the adjacent tissues. They are dignosed most often in the second decade of life, and have no predilection for jaws. The treatment is surgical excision and there is no expectancy of recurrence or serious complications after removal.

Leukemia is malignant tumor that abnormal cells increase in bone marrow because of abnormality of stem cell and result in anemia, thrombocytopenia, infection & infiltration in other tissue. Leukemia has 5.9% in incidence, following to stomach and uterine cancers and tend to increasing. There are four types of leukemia: acute lymphocytic leukemia, acute myelocytic leukemia, chronic lymphocytic leukemia, chronic myelocytic leukemia. In leukemia, there are swelling of gingiva, bleeding anemia and delayed wound healing in oral cavity. In addition, it is likely to bleeding in ilp, tongue and gingiva, because of decreased platelet. In oral region, candidiasis & ulcer is seen frequently, and secondary infection may occur through the ulcer. Chemotherapeutic agents may result in stomatitis, neuritis, xerostomia in oral mucosa. There is higher incidence in hypodontia, hypoplasia than common case, and there are more tendency in hemorrhage and infection.

The calcifying odontogenic cyst is considered to occupy a position between a cyst and an odontogenic tumor-having some characteristics of both. The calcifying odontogenic cyst is a slow-growing commpletely benign codintion. It occured with equal frequency in the maxilla and mandible, their review of cases showed that 47% occured before 31 years of ages, and that 75% of the lesions were situated anterior to the first molar teeth. Most of the lesions are intrabony, but some occur in the soft tissue and may cause a saucering of the adjacent bone, unerupted teeth and root resorption were observed in approximately one half of the cases. The radiographic appearance in of a cystlike radiolucency containing quite distinct radiopaque foci. The microscopic picture is unique for an oral lesion and the cells above the basal layer are irregular in arrangement and surround nests or sheets of large ghost epithelial cells filled with atypical-appearing keratin. Since the calcifying odontogenic cyst has a tendency for continued growth, surgical enucleation is the treatment of choice. Recurrence occur on occasion.

최근에 측두하악장애(Temporomandibular Disorder, TMD)는 해마다 증가하는 경향을 보이고 있다. 측두하악장애는 저작근, 측두하악관절 및 그와 관련된 구조물의 많은 임상증상을 포함하는 포괄적인 용어이다. 측두하악장애로 치과에 내원하는 환자는 여성이 많으며, 각 연령별 분포에서 보면 10대 후반에서 20대 후반에 호발한다. 그러나 최근에는 호발연령이 낮아지는 경향을 보이고 있다. 이에 측두하악장애의 조기진단의 필요성이 요구되어지며, 본 논문에서는 진단의 한 방법으로 간편하면서 쉽게 시행할 수 있는 최대개구량을 측정하였다. 최대개구량에 관한 여러 보고가 있지만, 소아기의 전 연령을 대상으로 광범위하게 조사된 보고는 희귀하다. 이에 저자는 4세부터 13세까지 1775명의 어린이를 대상으로 최대개구량을 측정하였으며, 최대개구량과 연련, 신장, 체중에 관한 상관관계를 조사하여 악관절장애 진단의 기초적인 참고자료로 이용하고자한다. 본 연구에서는 4세에서 13세까지의 1775명(남자943명, 여자832명)을 대상으로 최대개구량과 연령, 신장, 체중의 상관관계에 관한 비교분석을 시행하여 다음의 결론을 얻었다. 1. 4세에서 12세까지의 연령군중 4세, 8세, 12세의 평균 최대개구량을 보면 남자의 경우 각각 40.16mm, 47.32mm, 50.54mm였고, 여자의 경우 각각 39.79mm, 44.85mm, 48.09mm였다. 2. 연령이 증가함에 따라 최대개구량은 증가하는 경향을 보였고, 남자가 여자보다 큰 측정치를 보였다. 3. 신장이 증가함에 따라 최대개구량은 증가하는 경향을 보였으며, 105cm 이상 115cm 미만을 제외하고는 남자가 여자보다 큰 측정치를 보였다. 4. 체중이 증가함에 따라 최대개구량은 증가되는 경향을 보였으며, 모든 군에서 남자가 여자보다 큰 측정치를 보였다. 5. 최대개구량과 연령, 신장, 체중간의 관계에서 유의한 순상관 관계를 보였으며, 신장이 가장 높은 상관성을 보였다. Recently, tempormandibular disorder(TMD) shows an tendency to increase every year. TMD is a collective term embracing a number of clinical problems that involve the masticatory musculature, temporomandibular joint(TMJ) and associated structures, or both. TMD, viewed in distribution of age, often occurred from late teens to late twenties. But recently, the age of occurrence tends to be lower. Accordingly, early diagnosis of tempormandibular disorder is very important. In this study, we measured the maximum mouth opening which is simple and easy to carry out as a way of TMD diagnosis. In this study, the maximum mouth opening was examined for 1,775 children from 4 to 12 years of age. We compared the relationship between the maximum mouth opening with the age, height, and weight. The results obtained were summarized as follows; 1. The mean maximum mouth openings of 4, 8, and 12 year of age were respectively 40.16mm, 47.32mm, 50.54mm for male, 39.79mm, 44.85mm, 48.09mm for female. 2. The maximum mouth opening increased with age, and the values were greater in male than in female. 3. The maximum mouth opening increased wit height, and the values were greater in male than in female except between 105cm and 115cm. 4. The maximum mouth opening increased with weight, and the values were greater in male than in female. 5. The correlation between the maximum mouth opeing with the age, height, and weight was all significant and height showed the highest correlation.
