  • 1996년 우리나라의 서해연안에서 채집된 뱀장어목 어류 1종을 동정한 결과 지금까지 우리나라에서는 서식이 확인되지 않았던 Synaphobranchidae과에 속하는 Dysomma anguillare Barnard로 동정이 되었다. 본 종은 외부 형태적으로 D. ophisthoproctus와 유사하나, 상하악의 앞부분은 근육질의 작은 돌기를 가지며, 눈이 퇴화되었고, 체장은 아주 짧고 꼬리가 매우 길며, 항문이 가슴지느러미의 끝 아래에 위치하고 비늘이 없는 점 등이 특징적이다. 본 종은 체장이 짧고 꼬리가 길다는 특징에 따라 한국명을 긴꼬리장어과, 긴꼬리장어속, 긴꼬리장어로 명명하였다.

  • Mucoepidermoid carcinomas (MECs) arising within the jaws as primary central bony lesions are termed central MECs. Central MECs are extremely rare, comprising 2-3% of all mucoepidermoid carcinomas. We herein report a rare case of central MEC of the maxilla in a 52-year-old male whose plain radiographs showed a "ground glass" pattern and computed tomographic images, a hypodense mass with numerous calcifications. To the best of our knowledge, this is the first report of central MEC showing a "ground glass" appearance.

  • A specimen of Aetobatus flagellum was collected at Uljin in June 2005 for the first time in Korea. This specimen is characterized by the cephalic fin, the long snout, the dorsal fin between pelvic fins, spiracles on the dorsal side of the disc, the deeply notched nasal curtain and the one row of the teeth in the lower and the upper jaws. And unlike Aetobatus narinari, it does not have any spots on the its dorsal side of the disc. We report this specimen as the first record from Korea and name it 'Bak-jui-ga-o-ri' in Korean.

  • BRONJ(Bisphosphonate Related Osteonecrosis of Jaws) is not easy to be managed because it responds less predictably to established surgical treatment algorithms for osteomyelitis or osteoradionecrosis. The guidelines recommend that any kind of surgery should be delayed if possible. In the latest stage-dependent recommendations of the AAOMS in 2009, a conservative regime with antibiotics, antibacterial mouthe rinses and pain control in stages 0 to II. Some investigators have described the benefits of early osteotomy with primary wound closure. However, there are only a few publications with a standardized surgical concepts. In this reviews, various aspects of diagnosis and management of BRONJ will be discussed.

  • Maxillary growth is hindered by the restricting pressure from the scar tissue formed after lip closure and palate closure surgeries of the cleft. Therefore, the anteroposterior skeletal relationship of both jaws exacerbates as patient grows. Conventional facemask treatment is valuable for dentoalveolar compensatory treatment and for very mild maxillary hypoplasia. To achieve further maxillary protraction, bone-anchored facemask or bone-anchored maxillary protraction can be attempted. For moderate maxillary hypoplasia, surgical orthodontic treatment after growth completion can be an efficient treatment reducing uncontrollable problems. For moderate to severe maxillary hypoplasia, distraction osteogenesis (DO) can be used alone or with later surgical orthodontic treatment. To compensate the severe relapse after DO, overcorrection and bone plate placement after DO are recommended. In case of hypernasality, maxillary anterior segmental distraction osteogenesis can be chosen to prevent exacerbation of the hypernasality.

  • A majority of patients who sustain injuries to the peripheral sensory nerves of the face and jaws experience a slow but gradual return of sensation that is functional and tolerable, if not the same as before the injuries. However, long-term effects of such injuries are aggravating for many patients, and a few patients experience significant suffering. In some of these patients, posttraumatic symptoms become pathological and are painful. The predominant painful components are (1) numbing anesthesia dolorosa pain, (2) triggered neuralgiaform pain, (3) burning and aching causalgiaform pain, and (4) phantom pain. This is a case report of conservative management of traumatic neuralgia and neuritis as part of posttraumatic pain syndromes in geriatric patients who have undergone the teeth extraction and alveoloplasty.

  • The author analyzed the clinical and radiographic findings of 109 malignant tumors of epithelial origin occured in the jaws of the patients visited the infirmaries of Dentistry, Chosun University and several university in Korea during 1978 to 1988. The observed results were as follows: 1. It appeared that 93 % of the total 397 cases diagnosed as oral malignant tumors were squamous cell carcinomas. 2. The incidence ratios between nodular type and ulcer type were 4 to 1 in maxilla and 3 to 1 in mandible. 3. In nearly 50% of all patients complained of pain due to impingement of tumor mass or ulcer. 4. Most of carcinomas of maxilla eventually invaded into maxillary sinus and palate. 5. Characteristic features on the radiographs were the lesion with ill-defined border, the direct destruction of the alveolar bone and anatomical landmark without displacement of the involved teeth and the gray shadow of the tumor mass in the lesion.

  • 하악에 발생한 45예, 상악에 발생한 1예로 총 46예의 법랑모세포종이 연구되었다 환자의 평균연령은 34세였으며 성별에 따른 차이는 없었다. 가장 흔한 징후는 악골 또는 안면의 종창이었다. 소구치-대구치-하악지 부위를 침범한 예가 20예(43.5%)였다. 다방성 병소가 26예(56.5%)에서 발견되었다. 방사선학적 형태는 환자의 연령이나 조직학적 형태와는 상관관계가 없었다. 단방형 형태는 주로 젊은 환자에서 발견되었으며 10대에 호발하는 상관관계를 나타내었다(P<0.05). 근치 또는 보존적 수술로 치료를 받은 분석 가능한 18명의 환자에서 재발율은 33.3%를 나타내었다. 다방성 형태(36.4%)학적 행태를 명확하게 예측하기 위해서는 좀 더 상세한 임상 및 방사선학적 변수가 첨가되어야 할 것으로 사료되었다.

  • Root resorption is loss of dental hard tissue as a result of clastic activities. The dental hard tissue of permanent teeth does not normally undergo resorption, except in cases of inflammation or trauma. However, there are rare cases of tooth resorption of an unknown cause, known as "idiopathic root resorption". This report would discuss a rare case of multiple idiopathic resorption in the permanent maxillary and mandibular teeth of an otherwise healthy 36-year-old male patient. In addition to a clinical examination, the patient was imaged using conventional radiography and cone-beam computed tomography (CBCT). The examinations revealed multiple external and internal resorption of the teeth in all four quadrants of the jaws with an unknown cause. Multiple root resorption is a rare clinical phenomenon that should be examined using different radiographic modalities. Cross-sectional CBCT is useful in the diagnosis and examination of such lesions.

  • A female Korean native calf with diprosopus was examined macroscopically and radiographically. Anterior head duplication (diprosopus) was observed and all structures caudal to it were normal. She had two complete mouths, four eyes and three ears. Single tongue was present in each oral cavity. The two tongues were joined at their base just posterior to the single epiglottis. Both oral cavities led jointly into a common pharynx and one esophagus. One laryngeal cavity communicated with one common trachea. The lower jaws were immobile because of overlapping mandibular rami. The atlas was complete, and two anterior articular cavities articulated with the lateral condyles of the occipital bones of each skull. The cerebrums were fused each other at their caudal portion, and the giri and sulci were underdeveloped. The cerebellums were also completely fused, and they had not characteristic appearance of the vermis. The spinal cord showed normal appearance.
