측두하악관절통환자에 있어서 이온영동법을 이용한 Prednisolone의 동통조절효과
전용현 慶北大學校 齒科大學 1994 慶北齒大論文集 Vol.11 No.2
측두하악관절통을 주소로 경북대학교병원 구강내과에 내원한 환자들 중 다발성 관절염, 류마티성 관절염 및 전신 질환이 없고 유추지수가 2이상이며 촉진지수가 1이상인 30명을 대상으로 1% Prednisolone, 2% Prednisolone, 생리식염수를 이온영동법을 이용하여 1.0mA, 12분간 각각 1ml를 투여하여 다음과 같은 결과를 얻었다. . 치료 전후의 동통감소 비교에서 생리식명수 투여군은 유추지수의 유의한 감소가 있었으며 1% Prednisolone투여군과 2% Prednisolone투여군에서는 유추지수, 촉진지수의 유의한 감소와 압력통각역치의 유의한 증가가 있었다. . 유추지수는 각군 사이에 유의한 차이가 없었다. . 통각압력역치는 생리식염수를 투여한 군과 비교하여 1% Prednisolone과 2% Prednisolone 투여군에서 유의한 증가를 나타내었다. . 촉진지수는 생리식염수를 투여한 군과 비교하여 1% Prednisolone과 2% Prednisolone 투여군에서 유의한 감소를 나타내었다. . 1% Prednisolone 투여군과 2% Prednisolone 투여군 사이에는 모든 측정방법에서 유의한 차이가 없었다. 30 patients with temporomandibular joint pain participated in this study. Inclusion criteria for participation were positive to palpation and above 2 of visual analog scales(VAS) and exclusion criteria for participation were polyarthralgia, reumatic arthralgia, and systemic diseases. The patients were randonly assigned to three group. : one group to administration of 2% prednisolone : one group to administration of 1% prednisolone : one group to administration of saline using iotophoresis. The results were as follow: In pain decrease of befor and after treatment, saline group was significantly decreased in VAS and 1% prednisolone group and 2% prednisolone group were significantly decreased in VAS, Pain pressure threshold(PPT) and Palpation index(PI). There was no significant difference in VAS at each group. PPT in the group of administration of 1% prednisolone and 2% prednisolone were significantly higher than that in administration of saline group. PI in administration of the group of 1% prednisolone and 2% prednisolone were significantly lower than that in administration of saline group. There was no significantly difference between the group of administration of 1% prednisolone and administration of 2% prednisolone in all methods.

PURPOSE. The purpose of this study was to identify the complex course of the mandibular canal using 3D reconstruction of microCT images and to provide the diagram for clinicians to help them understand at the interforaminal region in Korean. MATERIALS AND METHODS. Twenty-six hemimandibles obtained from cadavers were examined using microCT, and the images were reconstructed. At both the midpoint of mental foramen and the tip of anterior loop, the bucco-lingual position, the height from the mandibular inferior border, the horizontal distance between two points, and position relative to tooth site on the mandibular canal were measured. The angle that the mental canal diverges from the mandibular canal was measured in posteriorsuperior and lateral-superior direction. RESULTS. The buccal distance from the mandibular canal was significantly much shorter than lingual distance at both the mental foramen and the tip of anterior loop. The mandibular canal at the tip of anterior loop was significantly located closer to buccal side and higher than at the mental foramen. And the mental canal most commonly diverged from the mandibular canal below the first premolar by approximately 50º posterior-superior and 41º lateral-superior direction, which had with a mean length of 5.19 mm in front of the mental foramen, and exited to the mental foramen below the second premolar. CONCLUSION. These results suggest that it could form a hazardous tetrahedron space at the interforaminal region, thus, the clinician need to pay attention to the width of a premolar tooth from the mental foramen during dental implant placement.

The aim of this study was to investigate clinical assessment and cephalometric characteristics in 10s patients with condylar resorption, who visited in the Department of Oral Medicine Kyungpook National University Hospital at 2006, by use of panorama, transcranial view and lateral cephalometric radiograph. The results were as follows; 1. Clinical assessment 1) Total number of patients were 59. Female was 47 and male was 12, Females were predominant and patient's age ranged from 12 to 19. 2) Most of the patients had Grade II condyle resorption. 3) The number of who had Class I occlusion was 27, which was the largest group. The number of patients with openbite was 20. Average overjet was 3.58mm and average overbite was 0.97mm. 4) Most of the patients had parafunctional habit. 5) The patients of showing the pain in condylar resortion was 41 and the case of not showing the pain was 18. 6) Treatment duration of 23 patients were less than 1 month, 28 patients were treated with supported therapy. 2. Cephalometric Characteristics 1) A 16-year-old female patients showed smaller SNA, SNB and larger articular angle significantly as compared with those of normal group. 2) A 17-year-old female patients showed smaller SN, SAr, TPFH, ramus height and larger SN-GoMe, FMA, articular angle significantly as compared with those of normal group. 3) Over 18 years old female patients showed smaller SN, SNB, TPFH, ramus height and larger ANB, FMA, SN-GoMe, LAFH, articular angle, gonial angle significantly as compared with those of normal group. 4) Over 18 years old male patients showed smaller SN, TPFH, ramus height and larger FMA, SN-GoMe, LAFH, articular angle, gonial angle significantly as compared with those of normal group. 5) There was no significant difference between 10s and normal group in mandibular body length.
