  • 목적: 단순악관절 진동군에서 좌/우 진동 중 유의한 진동의 감별법을 연구하는 것이다. 연구 재료 및 방법: 단순악관절 진동만을 갖고 있고 측두하악관절 질환의 제 증상이 없는 단순악관절 진동그룹 30명의 60개 관절에서 44쌍의 진동을 기록하였고 대상자의 인지와 검사자의 촉진, JVA 검사 결과를 비교하였다. JVA로 기록된 진동의 주파수 스펙트럼, 진동파형 시간차 위상변위 분석, 수치 분석을 통해 좌/우 진동 중 유의한 진동을 감별하였다. 결과: JVA 분석결과 양측성 진동은 한 건도 없었으며 유의한 편측 진동은 42개로 감별되었다. 시간차 위상변위를 보이는 것은 11쌍이었고 이 중 한 쌍을 제외한 모든 진동에서 전달된 측의 진동이 발생측 진동보다 진동 총에너지(total integral) 값은 더 작고 > 300 / < 300 ratio는 같거나 더 큰 특징을 보이는 것을 관찰하였다. 또한 진동 총에너지 값이 10 이하로 작고 시간차 위상변위를 보이지 않아 좌/우 감별의 근거가 모호한 나머지 진동 모두에서 진동 총에너지 값이 더 작은 쪽의 > 300 / < 300 ratio가 더 큼을 관찰하여 이를 좌/우 감별의 근거로 삼을 수 있었다. 결론: JVA로 좌/우 진동 중 유의한 진동을 감별하기 위해서는 주파수 스펙트럼, 시간차 위상변위 및 수치 분석 등이 모두 고려되어야 한다.

  • This 32 year-old male army officer was admitted with complaints of thumb size mass on buccal musoca which onterfere with mastication. Routine laboratory test revealed W.N.L. and the results of the excisional biopsy was Plemorphic Adenoma of salivary gland origin which was on the left buccal musoca( of 21 year-old male army officer). The size of tumor mass was 1.0 x 1.2 x 0.8cm, hard, encapsulated and seperated completely from surrounding tissue when enucleated surgically. Wound was healed unventfully and the result was good.

  • Inverted maxillary incisor is that maxillary incisor rotates counterclockwise direction. The cause of this 'Inverted incisor' is the injury of the deciduous predecessor transmitted to the developing permanent tooth germ or displacement of permanent tooth crown portion from unknown origin. Dilaceration, defined as a distorted root from, may result from mechanical injury during eruption period or ectopic development of tooth germ. This article presents a case of an inverted and dilacerated maxillary right central incisor. Through orthodontic traction, the dilacerated and inverted incisor was successfully moved into the proper position.

  • Facial nerve paralysis following delayed complication after trauma was rare and hard to find reason After symptom of facial nerve paralysis was found, careful clinical and neuropathic investigation needed through electromyography and nerve conduction velocity. It is necessery to Hewing that functional degenaration of nerve conduction was irresible or not. It is important to determine if palsy is already present alter trauma or some later time because origin of viral infection or temperature change may possible.

  • 악성종양은 상피성의 암종(carcinoma)과 결체직성의 육종(sarcoma)으로 분류된다. 최근 암환자의 발생은 점차 증가되는 추세이며, 우리나라에서도 사망원인 중 뇌졸증 다음으로 암이 차지하는 비율이 높다. 이러한 암은 침윤성(infiltrative)인 성장으로 인하여 인접 정상조직을 급격히 파괴시키며, 해당 임파절을 따라 신체 다른 부위로 전이(metastasis)된다. 임파절에 전이되기 전에 조기발견된 암은 70%의 5년 생존률을 보이는 반면, 임파절에 전이된 후에 발견된 암은 30%의 5년 생존률을 보인다. 따라서 암의 성공적인 치료를 위해서는 이의 조기발견이 매우 중요하다고 할수 있다. 그러나 불행하게도 많은 환자가 이미 병소가 상당히 진행된 상태에서 내원하기 때문에 이의 근치가 어려우며, 예후 또한 좋지 않다. 이러한 암을 조기발견하기 위해서는 환자 자신의 관심뿐만 아니라 치과의사의 세심한 검진이 필요하리라 생각된다.

  • Aspergilloma of the maxillary sinus is considered rare in immunocompetent patients, but a considerable increase has recently been seen in the incidence of reported cases. Dental procedures involving the antral region are thought to predispose individuals to this form of aspergillosis. Because aspergilloma shares similar clinical features with other sinus pathologies, its diagnosis may be delayed. Thus, an early diagnosis confirmed by a histopathological examination plays a crucial role in the adequate management of aspergilloma. This article provides a concise review of the reported cases of aspergilloma associated with dental procedures and reports 2 new cases of aspergilloma in middle-aged female patients, with a presentation of their cone-beam computed tomographic findings.

  • Cyst is a closed sac, having a distinct membrane and division compared to the nearby tissue. Most cysts in the oro-maxillofacial area are odontogenic origin and found most commonly by oral and maxillofacial surgeons. Enucleation is considered as a definitive therapy in the management of these cysts. However, to select the treatment method for large cyst, consideration of position of the cyst, size and accessibility to main structure are needed. Marsupialization is a minimal invasive technique to treat large odontogenic cyst and tumor without damage to adjacent important structures. This study was undertaken to describe three cases of odontogenic cysts and tumors of jaws that were successfully treated with enucleation after marsupialization.

  • Pilomatricoma, calcifying epithelioma of Malherbe, is a benign skin neoplasm of hair matrix origin that is typically occurred in the head and neck region. It usually presents as a superficial, firm, solitary, slow-growing, and painless mass of less than 3 cm in diameter and most often occurs in young age under 20 years. The tumor does not express an aggressive behavior and surgical excision is the treatment of choice. The purpose of this article is to present a case of pilomatricoma of the preauricular region and to review the literature regarding pilomatricomas of the head and neck region.

  • A pleomorphic adenomas (so-called mixed tumors) predominantly localize in the salivary glands. of the mixed tumors affecting the major sailvary glands. 90% ocur in the parotid gland, about 9% occur in the submaxillary gland, and 1% occur in the sublingual gland. The sites of origin of tumors of the inor salivary glands, in order of frequency, are the palate, lip, tongue, cheek, anf floor of the mouth. In the case of reported here a tremendous large pleomorphic adenima (weighting 580gm, measuring 18X7cm) occuerd in the submaxilly gland which had been growing for about 20 years.

  • Recent study reported whether the cultured human pulp cells increase IL-8 secretion in response to SP stimulation22). In the present study, whether induction of IL-8 or MCP-1 in pulp tissue can be detected using enzyme-linked immunosorbent assay(ELISA) with ex vivo pulpal explants exposed to neuropeptides in culture and the IL-8 expression using immunohistochemical analysis with the ex vivo pulpal explants exposed to neuropeptides was evaluated. To investigate further mechanisms that may contribute to leukocyte recruitment in lesions of endodontic origin, the differential expression of IL-8 and MCP-1 by human dental pulp tissues stimulated in vitro by the Substance P was examined.(omitted)
