유상수,기우천,최재갑,Ryu, Sang-Soo,Kee, Woo-Cheon,Chol, Jae-Kap 대한안면통증구강내과학회 2000 Journal of Oral Medicine and Pain Vol.25 No.1

The authors assessed if there is a relationship between joint effusion and the presence of pain, and between joint effusion and disc displacement in 446 temporomandibular joints of 223 subjects who visited the Department of Oral Medicine, Kyungpook National University Hospital with the complaints of temporomandibular joint problem. The amount of joint effusion and the position of disc were determined from magnetic resonance images of the temporomandibular joints. The position of disc was classified into normal disc position, disc displacement with reduction (DDWR), and disc displacement without reduction (DDWOR). The amount of joint effusion was graded according to the extent of joint area of high signal intensity on T2-weighted MR images. These findings were correlated with one another and statistically analyzed. The results were as follows; 1. The incidence of temporomandibular joint pain Was higher in the joints with higher amount of joint effusion (P<0.001). 2. The proportion of temporomandibular joints with higher amount of effusion increased in the joints with more advanced articular disc displacement (P<0.001).

The purposes of the study were (1) to see if there are various types of disc configuration in normal temporomandibular joint and, if so, (2) to examine whether a specific type of disc configuration is susceptible to disc displacement, and (3) to see if a specific type of disc configuration and position is related to early relief of clinical symptoms from the anterior disc displacement without reduction to conservative treatment. From the magnetic resonance (MR) images taken for the patients with symptoms of temporomandibular disorders, 235 images as normal joint group, 255 images as anterior disc displacement with reduction group, and 249 images as anterior disc displacement without reduction group were selected, After the TMJ image was scanned and processed with Photoshop program, the disc configuration was determined, The incidence of various types of disc configuration was analyzed according to age, sex, diagnostic group, and the promptness of symptom relief. The disc position was also examined in relation to the promptness of symptom relief. The results were as follows : 1. In the normal joint group, biconcave type appeared most frequently and reversed, biplanar type in order, Posterior band enlarged and folded type didn't appear at all. On the other hand, in the anterior disc displacement without reduction group, folded type appeared most frequently and also posterior band enlarged type were found often. 2. There were statistically significant differences between sex and configuration of disc in the normal joint group and no statistically significant differences in the anterior disc displacement with reduction group and anterior disc displacement without reduction group, 3. There were no statistically significant differences between age and configuration of disc in the normal, anterior disc displacement with reduction group and anterior disc displacement without reduction group. 4. In anterior disc displacement without reduction group, rapid response was observed in biconcave and reversed type and delayed response was observed in folded type.

OBJECTIVES: This study was designed to measure the minimal cross-sectional areas and volumes of the pharynx in snoring patients and normal subjects and to see if there is an increase in the minimal cross-sectional areas and volumes of the pharynx with advancement of the mandible. METHODS: The pharyngeal computed tomography and 3-dimensional reconstruction were used to measure the cross-sectional areas and volumes of the nasopharynx, oropharynx, and hypopharynx with the jaw in normal position and in protrusive position in 7 patients with snoring and 7 control subjects while they were awake. RESULTS: The oropharynx was revealed to have the most narrow site in the pharynx and there was a tendency for the snorers to have a smaller nasopharyngeal and oropharyngeal cross-sectional area than normal subjects but not statistically significant. There were no significant differences in the volumes of the nasopharynx and oropharynx between the two groups. With advancement of the jaw the minimal cross-sectional area of oropharynx was significantly increased, and the volume was also increased but not significantly. The minimal cross-sectional areas and volumes of nasopharynx as well as hypopharynx were not significantly influenced by the advancement of the mandible. CONCLUSIONS: There was a tendency for snorers to have a smaller oropharynx than normal subjects and the oropharyngeal lumen was increased with the advancement of the mandible in both snorers and normal subjects.

이 연구의 목적은 악관절 내장증 환자에서 관절원판의 형태를 자기공명영상사진으로 평가하고 임상적 증상과의 관계를 알아보고자 하는 것이다. 악관절 내장증의 증상을 가진 90명의 환자에서 169개의 관절을 자기공명영상사진으로 관절원판과 하악과두의 관계를 기준으로 정상군, 정복성 관절원판 변위군, 비정복성 관절원판 변위군으로 분류하고 관절원판의 형태를 5가지로 나누었다. 임상검사는 측두하악관절통과 관절음의 유무를 확인하여 그 상관관계를 알아보았다. 실험 결과에서 측두하악관절통은 각 군에서 관절원판의 형태와는 정상군을 제외하고는 통계적인 유의성이 없었으며, 염증성 삼출액과 유의한 관계를 보였다. 관절음은 정복성 관절원판 변위환자에서 관절원판형태와 통계적으로 유의성을 보였으며, 비정복성 관절원판 변위환자에서도 상당수 관절음이 발생하였음을 알 수 있었다. 이 결과는 측두하악관절의 통증은 관절원판의 형태가 많이 변형될수록 통증이 심해지는 경우가 많았지만, 다른 여러 가지 원인들이 존재할 수 있으며, 관절음은 정복성 관절원판 변위환자에서 관절원판의 변형이 심할수록 관절원판이 정복할 때 발생될 수 있다는 것을 의미한다. 따라서, 임상적인 검사와 더불어 자기공명영상사진으로 정확한 진단을 함으로써 관절원판 변위의 적절한 치료가 행해질수 있으리라 생각된다.

The author has studied mandibular opening and closing movement patterns using mandibular kinesiograph in order to make basic data that is necessary to diagnose the mandibular movement function. The 83 normal subjects, who were students of the school of Dentistry, Kyungpook National University and Daegu junior Health College, were selected according to sampling criteria. The results were as follows: In the sagittal plane, crossover pattern had the highest incidence in male(72.7) and female(76.8%). There was no significant difference of distribution of hbbitual closing movement patterns between male and female. (p>0.05) There were differences between each patterns. (p<0.01) In the rrontal plane, there was no difference of distribution of male's opening and closing and closing movement patterns between habitual and maximum velocity (p>0.05),but differences between each subjects. (p<0.05) In the frontal plane, there was no dif erence of distribution of habitual opening and closing movement patterns between male and female. (p>0.05) In the frontal plane, the averahe number of habitual opening and closing pathways cross the midline was greater than that of maximum velocity.(p<0.05) The average of the maximum mandibular movement velocity of male was greater than female in opening and contact (p<0.01) and there was no difference between male and female in closing. (p>0.05)

Eagle증후군의 증례와 문헌 고찰

기우천,곽준봉 대한 두개하악장애학회 1989 대한두개하악장애학회지 Vol.- No.1

Eagle증후군은 경상돌기의 신장 및 경상설골인대나 경돌하악인대의 석회화와 관련하여 인후부의 이물감, 연하곤란, 발음곤란, 연관통 및 개구장애등을 주증상으로 하는 질환으로 Styloid syndrome, Stylohyoid syndrome, Elongated styloid process syndrome, Styloid process neuralgia 등 여러가지 명칭이 사용되고 있다. Eagle증후군의 원인은 아직 명확하지 않으며, 나타나는 동통의 기전에 따라 classic type과 carotid artery type으로 분류되는데 classic type은 대부분 편도선 절제 후에 증상이 나타나며, 주증상에는 인후부의 이물감, 연하곤란, 연관통등이 있고, carotid artery type의 주증상은 머리를 돌릴때 나타나는 방사상 동통 및 두통 등이다. 감별 해야할 질환으로는 설인신경동, 측두하악장애, 매복지치, 경부 관절염, 종양등이 있다. 경상하악인대의 석회화에 대해 1652년 Marchelti가 최초로 보고한 이래 1937년 Eagle은 경상돌기의 신장과 관련된 증후군에 대한 증례보고를 한바 있으며 이를 Eagle 증후군으로 명명하였다. 그후 Stafne의 stylohyoid chain의 방사선학적 소견에 관한 연구, Kaufman의 styloid process의 여러 형태에 관한 연구, Steinman의 styloid syndrome의 pathogenesis에 관한 연구와 Dayal, Curphey, Ettinger, Mosser, Gossman 등 의 styloid syndrome 에 대한 대수의 증례보고가 있었으며, 또한 Correll은 일반 성인에서 경상돌기 신장 및 경상설골인대 석회화의 성별 연령별 발생 빈도에 대하여 보고 하였다. 그러나 경상돌기의 신장 및 경상설골인대의 석회화와 관련하여 임상적 증상이 나타나는 경우의 발생빈도에 대하여는 보고가 희소한 상태이다. 이에 저자는 전남대학교 병원에 내원하여 Eagle증후군이라 진단되어진 환자와 문헌상의 증례보고를 종합하여 Eagle증후군에 대해 다소의 지견을 얻었기에 이에 보고하는 바이다.

Pulsed Nd:YAG 레이저 조사와 불소 화합물 도포가 초기 우식 법랑질의 표면 경도에 미치는 영향

곽준봉,기우천 전남대학교 치과대학 1996 전남치대논문집 Vol.8 No.1

This study was designed to determine the most effective concentration of fluoride and energy density of laser irradiation for the anticarious effect. For this study, surface hardness in enamel was measured before and after irradiation with pulsed Nd : YAG laser and the topical application of fluoride. Of the permanent mandibular anterior bovine teeth, healthy, carious free ones were used. Three hundred specimens were made. Specimens within 25~45 Vickers hardness numbers were assigned to 20 control and experimental groups : each containing 15 specimens. After forming artificial carious lesions, 10 J/㎠, 20 J/㎠, and 30 J/㎠ energies were irradiated on the enamel surface of each experimental group. Also NaF, NH_4F, Elmex gel(amine fluoride) and APF gel fluoride compounds were applied topically. Next, all the specimens were placed into the pH circulatory procedures for eight days. Vickers hardness numbers were measured using a microhardness tester. Surface changes of the enamel were observed using an scanning electron microscope. The comparative analysis yielded the following results : 1. The reduction of surface hardness of the enamel surface was less in all groups with fluoride application than in the group without fluoride application. 2. The APF gel group with 10 J/㎠ irradiation showed the lowest reduction of surface hardness. 3. The reduction of surface hardness of the enamel surface in the group of laser irradiation without fluoride application not showed any significant difference according to the energy density of the laser. 4. Under the scanning electron microscope, in enamel irradiated with 10 J/㎠ showed appearance similar to acid etching surface. In enamel irradiated with 20 J/㎠, fine enamel crack was detected. In enamel irradiated with 30 J/㎠, severe enamel crack and fusion of enamel were detected. These results suggest that one could obtain the best anticariogenic effects without damage to teeth in the group of application of APF gel after laser irradiation with 10 J/㎠.
