Cervicofacial subcutaneous emphysema is defined as the abnormal introduction of air into the subcutaneous tissues of the head and neck. It is mainly iatrogenic and traumatic in origin. Our two case reports are also due to the same cause, but the features of the trauma and the site of the dental treatment are different from the existing reports. A 29-year-old man visited our hospital with facial swelling and pain after experiencing facial trauma in a soccer game. Another 55-year-old woman visited with similar symptoms after replacement of her maxillary anterior fixed prosthesis. In the two cases presented, subcutaneous emphysema was gradually treated with no complications during antibiotic prophylaxis and supportive care. In this paper, we report two cases of traumatic and iatrogenic subcutaneous emphysema and their diagnoses, etiologies, complications, and treatments based on a literature review.

저작운동을 중추신경계와 말초조직의 작용에의해 일생동안 학습과 적응의 가정을 통해 이루어진다. 저작의 양상은 유치가 구강내에 맹출되면서 이루어지며, 상하악 치아의 접촉, 점막과 혀 및 치아상호간에 일어나는 접촉과 치근막의 고유수용기와 악관절 수용기등에 의해 조정되어 최종적으로 에너지소비가 적고 동통이나 불편함이 없이 최대의 효율을 나타내는 양상으로 된다. 그러나 원활한 저작과 하악은동을 이룩하기 위해서는 저작근, 악관절, 상하악 치아의 교합등이 서로 조화를 이루어야 한다. 만일 외상에 의해 악관절의 기능장애가 오면 저작근활동이 변화하고 이에따라 교합장애를 야기한다. 또한 치아를 상실하거나 대합치아간의 조기접촉이 있으면 교합장애가 원인이 되어 근육활동이 변화와 악관절 기능장애를 초래한다. 그리고 때로는 지나친 근육의 활동(이갈이, 지속적 긴장성 수축)에 의해 지나친 치아의 마모로인한 교합장애나 악관절장애를 일으킬 수 있다. 따라서 하악의 기능을 충분히 이해하기 위해서는 교합의 형태학적 관계와 더불어 저작계의 기능적인 면도 고려하여 그 상호관계를 검토하여야 하며 본문에서는 교합에 관련된 저작근의 작용과 이에 영향을 주는 요인 및 교합장애와 근육활동장애의 연관성에 관해 고찰코자 한다.

평활근육종은 주로 사지와 몸통에 주로 발생하며, 악하선의 원발성 평활근육종은 매우 드물다. 악하선의 원발성 평활근육종은 증상과 방사선 검사 모두에서 비특이적이며, 치료는 광범위 절제술이다. 최근 저자들은 악하선에 발생한 원발성 평활근육종을 광범위 적출술을 시행한 후에 술후 방사선 치료를 시행하여 치험하였기에 문헌 고찰과 함께 보고하는 바이다. 악하선의 평활근육종은 드물지만, 방사선 검사에서 경계가 분명하고 조영 증강이 잘되며, 세침흡입검사에서 방추세포가 발견될 경우에 감별 진단으로 고려해야 한다.

Mini-dental implants for overdenture applications are increasingly popular due to their ease in placement with simplified, less traumatic surgical protocols in limited-width alveolar ridges. However, the clinical decisions including implant number, position, and loading protocol must be based on a thorough evaluation and evidence-based diagnosis. Herein, we reported a case treated with the current method of mandibular mini-implant supported overdenture.

외상의 처치는 일반적으로 응급처치기(emergency 혹은 initial phase), 중간처치기 (intermidiate 혹은 planning phase) 그리고 항구치료기 (definitive phase)로 구분되며 응급처치의 범주내에서는 우선 환자의 생명유지를 고려하고 다음엔 창의 생활력(vitality)을 유지하여 장차의 조직결손과 기능적 결합을 예방하는 데 목적이 있다. 그러므로 구강 및 악안면의 광범한 외상은 기도확보, 대량실혈의 방지, shock의 예방 (수액보충 등) 및 감염대책 등의 순으로 응급대처하게 된다. 그러나 일반 개원임상의들이 자주 접하는 비교적 작은 외상에서는 위의 대원칙에 더하여 창상의 효과적인 1차적 처치에 더욱 관심을 갖어 조직의 괴사나 결손 및 변형으로 인한 기능적 심미적 장애를 최솔 하는 것이 중요하다.

This research aimed to discuss the necessity of education and evil through perspective of Sunja and Hannah Arendt. In case of Sunja, it was reviewed by his opinion about Sunja as the central figure. As for Arendt, it was researched with "Eichmann in Jerusalem" as the central figure which she wrote participating in the trial process of Eichmann who was a war criminal of Nazi. Sunja thought evil as the nature of people and understood that they all are originally selfish, envious, and seeking desire. Therefore, Sunja thought it is important to properly seek human desire. He claimed Haw Seong Gi Wi(化性起僞, changing evil human nature into goodness through manner) which changes human nature from evil to goodness. A teacher who leads evil into goodness is surely needed in the process of Haw Seong Gi Wi. At the same time, in the dimension of educational content it put stress on the role of Ye(禮, manner) which lets them realize discernment so that they properly seek human desire and Ak(樂, harmony) which harmoniously controls human emotion, and key point on education regarding Ye and Ak. As for Arendt, however, she recognized evil as normal one. Even though he thought that conforming the order of superior authority was the best value and then took evil of killing many Jews in thoughtlessness, Eichmann maintained that he did not take evil but only conformed the order. This way, people could take evil in thoughtlessness in totalitarianism, and it makes circumstance that they could not take goodness. Therefore they could take evil in thoughtlessness and experience the radical evil and the banality of evil. Accordingly, political praxis which guarantees people's plurality as the words and praxis is needed. It is named natality because the truth that they are born in this world is a starting point, and makes the essence of education. In this process, teachers have to be a representative of this generation for children as new social members, and be able to keep children's newness. Sunja and Arendt have the same equality and difference in that they referred to the necessity of education to overcome human evil. It is the same quality that goodness could recover the function of community and the practice of education is considered important in the goal of education and the dimension of directivity. It is different in methodical characteristic of education that Arendt, however, suggests praxis as the way that they express themselves in totalitarianism while Sunja thought that continuous practice piling up virtue for goodness is important.
