부분적 무치아증 : 다수 치아의 선천성 결손 Congenitally multiple teeth missing
박상억,나채영,최갑식 慶北大學校 齒科大學 1992 慶北齒大論文集 Vol.9 No.1
1984년에서 1991년까지 경북대 병원 치과에 내원하여 파노라마 방사선사진을 촬영한 환자들 중 선천성 결손치의 수가 4개 이상인 부분적 무치아증 환자 44명(남자 22명, 여자 22명)에서 나타난 401개의 선천성 결손치를 조사분석하여 다음의 결과를 얻었다. 1. 결손치의 수는 4개에서 22개로 다양하였으며 5개의 치아가 결손된 경우가 8증례로 가장 많았다. 2. 각 치아별 호발빈도는 상악 제2소구치, 하악 제2소구치, 상악 측절치, 하악 제1소구치순이었다. 3. 결손치가 양측성으로 발생한 경우는 약 60∼70%였다. 4. 치열의 4 quardrant 모두에서 결손된 치아는 제2소구치가 가장 많았다. The expression of congenitally missing teeth may range from one or a few missing teeth(hypodontia) to the agenesis of numerous teeth(oligodontia) to the failure of all the teeth to develop(anodontia), but clinically the term of oligodontia means four or more congenitally missing teeth in dentition. The authors observed 44 patients of oligodontia cases especially having four or more missing teeth who came to the Dental Infirmary of Kyungpook National University Hospital. In this study, all of 44 patients represented congenitally missing teeth bilaterally. Thirty-eight patients represented that missing teeth were found bilaterally in both jaws, but only four patients in the upper jaw and two patients in the lower jaw. And the maxillary second premolar was absent most frequently, followed by the mandibular second premolar, the maxillary lateral incisor, the maxillary first premolar, in descending order of frequency.

The objective of this study was to explore perceptions of dental student of patients with special care. Their satisfaction with education, and their professional attitudes and behavioral intentions concerning treating these patients were the issues of this paper. Paper-and-pencil survey data were collected from 289 dental students at the school of dentistry, Seoul National University. Most respondents agreed that it is important to be educated about providing care for patients with special needs at the school. The higher grade students they are, they got the higher degree of understanding about treating these patients and the more satisfaction with the education. However, their intentions to treat these patients in their future professional lives were negatively correlated with degree of students. Based on these findings, it is recommended that school curriculum about treating patients with special care be reconsidered to develop students’ comfort level in treating special needs populations.

경북대학병원 치과에 내원한 8세에서 27세까지의 환자 6,531명의 파노라마 X선사진에서 제3대구치를 제외한 선천성 결손치, 제3대구치의 선천성 결손, 과잉치의 발생율, 성별분포, 호발부위 및 수에 따른 분포를 조사하여 다음의 결과를 얻었다. 1. 제3대구치를 제외한 선천성 결손치의 발생율은 10.8%였으며, 남성이 44.6%, 여성이 55.4%였다. 하악 제2소구치가 23.2%로 가장 많았으며, 상악 측절치 18.4%, 하악 측절치 18.3%, 상악 제2소구치 15.4%의 순으로 나타났다. 결손치의 수는 1개인 경우가 48%로 가장 많았으며, 2개인 경우가 35.4%, 3개인 경우가 6.6%로 나타났다. 2. 제3대구치 선천성 결손의 발생율은 39.7%였으며, 남성이 48.6%, 여성이 51.4%였고, 상악 60.3%, 하악이 39.7%였다. 결손치의 수는 1개인 경우가 28.7%, 2개인 경우가 37.2%, 3개인 경우가 12.5%, 4개인 경우가 21.6%로 나타났다. 3. 과잉치의 발생율은 4.2%였으며, 남성이 65.7%, 여성이 34.3%였다. 상악 중절치부가 64.8%로 가장 많았으며, 상악 측절치부 13.2%, 상악 제3대구치 후방부 8.7%의 순으로 나타났다. 과잉치의 수는 1개인 경우가 79.9%로 가장 많았고,, 2개인 경우가 18.9%, 3개인 경우가 1.2%로 나타났다. The purpose of this study was to evaluate the prevalence and distribution of tooth number anomaly by means of the analysis of panoramic radiographs in 6.531 patients visited the Dental Infirmary of Kyungpook National University Hospital from January 1983 to May 1992. The results were as follows ; 1. The prevalence of congenitally missing teeth except third molar was revealed to be 10.8%, and there was a higher prevalence in females(44.6%) than in males(55.4%). Mandibular 2nd premolars(23.2%) were absent most frequently, followed by maxillary lateral incisors(18.4%), mandibular lateral incisors(18.3%), and maxillary second premolars(15.4%) in descending order of frequency. As to the number of congenitally missing teeth, the percentage of missing on tooth was 48%, missing two teeth was 35.4%, missing one tooth was 48%, missing two teeth was 35.4%, missing three teeth was 6.6%. 2. The prevalence of congenitally missing third molars was revealed to be 39.7%. There was a higher prevalence in the maxilla(60.3%) than in the mandible(39.7%). Maxillary right 3rd molars(30.6%) were absent most frequently, followed by maxillary left 3rd molar(29.7%), mandibular right 3rd molar(20.2%), mandibular left 3rd molar(19.5%) in descending order of frequency. 3. The prevalence of supernumerary teeth was revealed to be 4.2%, and there was a higher prevalence in males(65.7%) than in females(34.3%). They were found most frequently in maxillary central incisor area(64.8%), followed by maxillary lateral incisor area(13.2%), posterior area of maxillary third molar(8.7%) in descending order of frequency. As to the number of supernumerary teeth ; The percentage of one supernumerary tooth was 79.9%, two supernumerary teeth was 8.9%, three supernumerary teeth was 1.2%.

The authors observed a 27-year-old male patient who came to the Infirmary of Kyungpook National University Hospital who had complained of dull pain in right mandibular angle area 1 month ago. As a result of careful analysis of clinical, radiological, and histopathological findings, the authors diagnosed it as Ewing's sarcoma and obtained the results as follows: 1. In clinical examination, main clinical symptoms were continuous dull pain and gingival swelling on the 2nd and 3rd molar area of the right mandible. 2. In radiographic examination, ill-defined radiolucent area was seen on mandibular right angle area, and apparent periosteal reaction of sun-ray spicule was emanated from the lingual cortex of mandibular angle area. And computed tomograph also revealed moderate-defined soft tissue mass of the same area. 3. In histopathological examination, small round-shaped, and closely packed cells with scanty cytoplasm were observed in this specimen, and positive reaction in PAS staining was also observed.

Fibrous dysplasia is a benign fibro-osseous condition that is replacement of normal bone and marrow tissues by cellular fibrous tissue and immature bone, and it is divided into monostotic type and polyostotic type. Polyostotic fibrous dysplasia involves multiple bones, such as skull, jaw bones, femur and tobia. And it is also divided into two forms: the less severe Jaffe's type and the more severe Albright's syndrome. Clinically, it frequently occurs in the 2nd decade, and occurs more frequently in maxilla than in mandible. And the lesions of fibrous dysplasia tend to become static as skeletal maturity is reached. The authors experienced three cases of polyostosic fibrous dysplasia in the craniofacial area with the complaints of facial asymmetry due to painless swelling. And we discussed the clinical, radiological, and histopathological features of these cases with a brief review of the literatures.
