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.

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.

저자들은 인슐린 비의존형 당뇨병 환자에서 통증성 구강내 미란 및 전신성 수포성 미란을 동반한 심상성 천포창 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Various skin conditions such as diabetic dermopathy, necrobiosis lipoidica diabeticorum, bullosis diabeticorum, granuloma annulare occur frequently in diabetes, although common lesions may be associated by chance. Pemphigus vulgaris(PV) is a blistering skin disease seen predominantly in elderly patients. This disorder is characterized by the loss of cohesion between epidermal cells with the resultant formation of intraepidermal blisters. These blisters rupture easily, leaving denuded areases that may crust and enlarge peripherally. In half or more of patients, lesions begin in the mouth: approximately 90% of patients have oromucosal involvement at some time during the course of their disease. But the relationship of this disorder with diabetes is not clear. We experienced a case of pemphigus vulgaris associated with NIDDM in 67 years old woman who was admitted due to painful oral ulcer and control of blood glucose, so we present this case with a review of literatures.

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.

<P>We measured the absolute frequency of the optical clock transition <SUP>1</SUP>S<SUB>0</SUB>(<I>F</I> = 1/2)–<SUP>3</SUP>P<SUB>0</SUB>(<I>F</I> = 1/2) of <SUP>171</SUP>Yb atoms confined in a one-dimensional optical lattice and it was determined to be 518 295 836 590 863.5(8.1) Hz. The frequency was measured against Terrestrial Time (TT; the SI second on the geoid) using an optical frequency comb of which the frequency was phase-locked to an H-maser as a flywheel oscillator traceable to TT. The magic wavelength was also measured as 394 798.48(79) GHz. The results are in good agreement with two previous measurements of other institutes within the specified uncertainty of this work.</P>

This study was designed to examine the effects of histamine on gastric motility and its specific receptor in the circular smooth muscle of the human gastric corpus. Histamine mainly produced tonic relaxation in a concentration-dependent and reversible manner, although histamine enhanced contractility in a minor portion of tissues tested. Histamine-induced tonic relaxation was nerve-insensitive because pretreatment with nerve blockers cocktail (NBC) did not inhibit relaxation. Additionally, $K^+$ channel blockers, such as tetraethylammonium (TEA), apamin (APA), and glibenclamide (Glib), had no effect. However, $N^G$-nitro-L-arginine methyl ester (L-NAME) and 1H-(1,2,4)oxadiazolo (4,3-A) quinoxalin-1-one (ODQ), an inhibitor of soluble guanylate cyclase (sGC), did inhibit histamine-induced tonic relaxation. In particular, histamine-induced tonic relaxation was converted to tonic contraction by pretreatment with L-NAME. Ranitidine, the $H_2$ receptor blocker, inhibited histamine-induced tonic relaxation. These findings suggest that histamine produced relaxation in circular smooth muscle of human gastric smooth muscle through $H_2$ receptor and NO/sGC pathways.
