This study was designed to assess follow-up study of condylar bone changes using cone beam computed tomography in patients with osteoarthritis. The author performed clinical examination for osteoarthritis patients who visited Orofacial Pain Clinic, Department of Oral Medicine, Pusan National University Hospital. CBCT(Cone beam computed tomography) was taken for 228 joints in 114 subjects. After average 10 months, CBCT was retaken. A Oral medicine and Oral radiologist evaluated CBCT each other. Condyle bone changes were classified by no bone change, flattening, erosion, osteophyte and sclerosis. The obtained results were as follow. 1. The condylar bone changes of osteoarthritis in temporomandibular disorder were as follow: 1) The transitions of each types of condylar bone changes was maintained at the initial state of the majority. 2) The transition of erosion was distributed erosion, flattening, sclreosis, osteohyte in order. 3) The transition of flattening was distributed flattening, osteohyte, normal, sclreosis in order. 4) The transition of osteohyte was distributed osteohyte, erosion, sclreosis, flattening in order. 5) The transition of sclreosis was distributed sclreosis, osteohyte, erosion, normal in order. 2. The signs and symptoms according to transition of each types of condylar bone changes were as follow 1) In the transition of condylar bone changes from erosin to erosion, pain, noise, LOM and MCO had symptomatic improvement. In the transition of condylar bone changes from erosin to flattening, pain, LOM, MCO had symptomatic improvement. In the transition of condylar bone changes from erosin to no bony change, pain, noise, LOM had symptomatic improvement. In the transition of condylar bone changes from erosion to flattening than the maintenance of eosion, MCO had symptomatic improvement. 2) In the transition of condylar bone changes from flattening to flattening, pain, noise and MCO had symptomatic improvement. In the transition of condylar bone changes from flattening to sclerosis, LOM had symptomatic improvement. 3) In the transition of condylar bone changes from osteophyte to osteophyte, pain, LOM and MCO had symptomatic improvement.

Liposclerosing myxofibrous tumor (LSMFT) is a fibro-osseous lesion of the bone with a marked predilection for the intertrochanteric region of the proximal femur. It is characterized by a complex mixture of histological elements including fibrous dysplasia-like features, myxofibrous tissue, lipomatous area, ischemic ossification, xanthoma cells and pseudo-Paget's bone. Though some consider LSMFT as a variant of the fibrous dysplasia, intraosseous lipoma, or other benign osseous lesions, recently LSMFT is emerged as a genuine clinicopathologic entity. We experienced a 48-year female patient with typical histologic and radiologic findings of LSMFT. It was located at the intertrochanteric area of the femur. Radiologically, the lesion was radiolucent and ground-glass appearance with sclerotic rim in the plain film and magnetic resonance imaging. Histologically, myxofibrous tissue, lipomatous area and fibrous dysplasia-like features were predominant findings.

A 3-year-old Pit bull terrier dog had left hindlimb lameness for 3-weeks. On plain radiographs, geographic osteolysis with well-defined edges and marginal sclerosis was identified in medial aspect of left proximal tibialmetaphysis. Surgical debridement and curettage was performed. Coagulase negative Staphylococcus spp. grew on a culture specimen obtained during surgery, and Brodie's abscess was diagnosed.

There are very few reports of the restoration of tooth loss using dental implants in patients with diffuse sclerosing osteomyelitis (DSO). Because the patients with DSO have unfavorable bone quality for osseointegration of dental implants, additional considerations such as surgical trauma, infection control, and an extended healing period are essential when placing dental implants. The purpose of this study is to report on the success of osseointegration of a dental implant in the patient with DSO.

Thirty rabbits underwent femoral lengthening using monolateral external fixator to evaluate results and complications of limb lengthening. Twenty rabbits survived until consolidation of callus formed at the lengthening site after finishing lengthening. Ten rabbits were sacrificed during femoral lengthening because of complications. Survived 20 rabbits were classified to two groups according the amount of lengthening: group I (10% lengthening of the femoral length); group II (20% lengthening). There was no significant difference of consolidation time between two groups (p=0.25). Varus angulation at the lengthening site occurred in 60% of two groups and the amount of varus angulation in group II was larger than that of group I. Degenerative change of articular cartilage at the medial condyle of the distal femur was found in 30% of group II. Of sacrificed ten rabbits, 5 had pin loosenings with pull an of pins from the femur, 2 had fermoral fractures around the pin-tract site, and 3 had severe osteomyelitis of the femur around the pin-tract site.

골화석증(Osteopetrosis)은 전신의 뼈가 대리석 모양으로 골 경화를 일으키며 골수강의 폐쇄 및 골의 취약성을 보이는 드문 질환이다. 성인형(Adult form)은 우성 유전되며 경미한 증상을 나타낸다. 반면에 유아형(Infantile form)은 열성 유전되면서 심각한 증상을 나타내고, 조기에 사망에 이를 수도 있다. 골화석증은 골격계, 조혈계, 신경계에서 다양한 증상을 유발한다. 본 증례의 목적은 드물게 발생하는 유아형 골화석증을 가진 2 명의 환아를 치료한 후, 그 질환과 치과적 관리에 대해 고찰하고자 함이다. 첫 번째 증례는 골화석증으로 진단된 5세 8개월 남환이었다. 임상 및 방사선 검진 결과 악골 및 치아의 변형을 나타내었으나, 특별한 병적 소견이 없어 예방 치료 및 주기적인 검진 시행하였다. 두 번째 증례는 중증도의 치아우식증을 가진 환아로 의료진과의 협조 하에 수혈한 후 발치하였다. 유아형 골화석증은 다양한 구강 합병증을 유발하며, 질환의 심각성에 의해 치료 자체도 어렵다. 치과의사로서 골화석증 환아를 관리할 때에는 건전한 구강 상태를 유지하기 위한 지속적인 관심과 예방 치료가 필요하며, 아무리 간단한 발치나 치과 술식이더라도 의료진과 협조를 해야 한다.
