BMEMat, EarlyView.The PCLA‐SNP scaffolds can produce photothermal agents in situ under ultraviolet radiation. Then, the scaffold can release nitric oxide gas spontaneously and generate hyperthermia under near‐infrared laser to enhance ablation of bone tumors. Furthermore, the calcium and iron ions released from PCLA‐SNP scaffolds can accelerate bone regeneration ...

Automatic Tooth Arrangement with Joint Features of Point and Mesh Representations via Diffusion Probabilistic Models [PDF]
arXiv, 2023 Tooth arrangement is a crucial step in orthodontics treatment, in which aligning teeth could improve overall well-being, enhance facial aesthetics, and boost self-confidence. To improve the efficiency of tooth arrangement and minimize errors associated with unreasonable designs by inexperienced practitioners, some deep learning-based tooth arrangement ...

A Case of Supernumerary Tooth in Tonsil
Korean Journal of Otorhinolaryngology-Head and Neck Surgery, 2014 25세 남자 환자가 수년 전부터 수개월 간격으로 발생한 좌 측편도 부위의 통증을 주소로 내원하였다. 환자는 만성 편도 선염 진단아래 타병원에서 간헐적인 치료를 받았으나 호전 후 재발이 반복되어 본원 이비인후과 외래에 방문하였다. 과거력 과 가족력상 특이사항은 없었으며 이학적 검사상 우측편도 는 Grade I, 좌측편도는 Grade III 정도의 비대칭으로 좌측편 도가 우측편도에 비해 커져 있었고 염증으로 인한 발적을 확 인할 수 있었다. 그외 비강 및 후두의 소견은 정상이었다. 구 강 및 치아 소견상 상악 좌측 제3대구치는 염증으로 인해 4개 월 전에 발치된 상태였고 나머지 상악 및 하악 치아들은 정상 이었다.
