Ossifying fibroma is a slow-growing benign neoplasm that occurs most often in the jaws, especially mandible. The tumor composed of bone develops within fibrous connective tissue. Some ossifying fibromas consist cementum-like calcifications, while others contain only bony material; however, mixture these calcification types commonly seen single lesion. Of craniofacial bones, mandible involved site, with lesion typically inferior to premolars and molars. jaw shows female predominance. reports...

This study aimed to evaluate the feasibility of a 3-dimensional (3D) planned surgical guide technique designed for impacted supernumerary teeth (STs) extraction using 3D printed simulation models. In total, 17 participants from two university hospitals were recruited. Each participant performed surgery with both conventional and techniques. The following parameters evaluated: (1) time required ST extraction, (2) area window opening, (3) volume material removed. Time was 213.65 ± 167.45 sec...

This study compared the demineralization resistance of teeth treated with silver diamine fluoride (SDF) to that varnish. A total 105 healthy bovine incisors were divided into control, varnish, and SDF groups. The enamel surface density change was then measured by micro-computed tomography (micro-CT) at three depths. demineralized zone volume on 3D micro-CT images evaluate rate. morphology assessed scanning electron microscope. had continuously decreased while increased in control varnish...

스티븐 존슨 증후군(Stevens-Johnson syndrome, SJS)은 피부와 점막에 광범위한 괴사를 초래하는 매우 심각한 급성 과민반응이다. SJS은 모든 연령대에서 발생할 수 있는 질환으로 원인은 명확하지는 않지만 대부분 약물 알레르기에 의한 것으로 알려져 있으며 그외에도 세균감염에 의해 유발되기도 한다고 있다. 전체 표피면적의 10% 이하에서 병변이 발생한 경우를 SJS라 하며 30% 이상에서 독성 표피 괴사융해라 정의한다. SJS는 1년에 100만명 인구 당 1 - 2명 미만에서 드물게 발생하나, 성장기 어린아이에게 경우 치아발육 등에 미치는 영향을 미치게 된다.6 7세경 상하악 제1대구치와 하악중절치의 맹출이 시작되고 이 시기에 치근의 발육이 함께 일어난다. 케이스의 환아의 6세경 SJS이 발병하였다. 현재 완치된 상태이나 몇몇 후유증이 남아있는 상태이다. 환아는 완성되는 치아에 국한되어 발육이상이 관찰되었다. 구강내 특징으로 이러한 전신질환을 진단하고 이로...
