Goldman and Cohen originally proposed a classification for infra-bony defects which referred to the number of. factor-BB was safe and effective in the treatment of periodontal osseous defects. In a follow-up trial, the same sample patients were again assessed 18 or 24 months following periodontal surgery. Substantial radiographic changes in the appearance of the defect fill were observed.
Osteochondral defects (OCD) are focal areas of articular damage with cartilage damage and injury of the adjacent subchondral bone. Terminology Osteochondral defect is a broad term that describes the morphological change of a localized gap in t.
Bone Regeneration in Osseous Defects Using Hydroxyapatite Graft and the Extent of Ossification in Osseous Defects Treated Without Grafts: A Comparative Evaluation. Article (PDF Available) in.Various classification systems have been proposed to describe furcation lesions and Glickman’s classification for many years seems to have been the most widely utilized in the sole clinical diagnosis with no reference to the prognostic value of the lesion itself. This article reviews the previous classification systems and proposes a new method to classify furcation lesions based on the.Most neurenteric cysts are found in the posterior mediastinum (Figs. 28A, 28B, and 28C) where they can extend into or communicate with the spinal canal and be associated with congenital osseous defects of the spine. Histologically, both neural elements and gastrointestinal epithelium are typically seen. Affected patients often present with pain, which usually leads to early imaging evaluation.

Periodontitis is a chronic inflammatory disorder that causes destruction of the periodontal attachment apparatus including alveolar bone, the periodontal ligament, and cementum. Dental implants have been routinely installed after extraction of periodontitis-affected teeth; however, recent studies have indicated that many dental implants are affected by peri-implantitis, which progresses.Read More
Research has shown that various cancers share common molecular mechanisms such as uncontrolled cell proliferation, mutation, and dysregulation of genes for cell proliferation, migration, and differentiation. Tumors with similar appearance can follow significantly different clinical courses and show different responses to therapy. This kind of clinical heterogeneity can be explained by dividing.Read More
Total Knee Arthroplasty Essay Etiology and Pathology The knee functions as a type of biological transmission whose purpose is to accept and transfer range of loads between and among the femur, patella, tibia, and fibula without causing structural or metabolic damage. Arthritic knees are like living transmissions with worn bearings that have limited capacity to safely accept and transmit forces.Read More
Osteogenesis imperfecta (OI), also known as brittle bone disease, is a group of genetic disorders that mainly affect the bones. It results in bones that break easily. The severity may be mild to severe. Other symptoms may include a blue tinge to the whites of the eye, short height, loose joints, hearing loss, breathing problems and problems with the teeth.Read More
Known defects in KS I proteoglycan processing are associated with ocular dysfunction and mutations in the KERA gene cause the disorder known as cornea plana type 2 (CNA2). In patients with CNA2 the cornea lacks the normal convex shape which prevents the correct refraction of light through the lens. Defective sulfation of keratan sulfates causes macular corneal dystrophy and defects in keratan.Read More
Veterinary Periodontal Disease Introduction Periodontal disease is the most common infectious disease of adult dogs. It is a progressive, cyclical inflammatory disease of the supporting structures of the teeth and is the main cause of dental disease and early tooth loss in dogs and cats. It affects over 87% of dogs and 70% of cats over three years of age. By the end of this chapter you should.Read More
They include congenital lesions associated with development of the osseous orbit (dermoid and epidermoid inclusion cysts), primary bone lesions that may involve the orbit (fibrous dysplasia, juvenile or psammomatoid ossifying fibroma, and Langerhans cell histiocytosis (LCH)), malignant tumors that involve multiple sites (granulocytic sarcoma), and hematogenous metastases. Most of these.Read More
Dental restorative materials are used to replace tooth structure loss, usually due to dental caries (dental cavities), but also tooth wear and dental trauma.On other occasions, such materials may be used for cosmetic purposes to alter the appearance of an individual's teeth. There are many challenges for the physical properties of the ideal dental restorative material.Read More
OI is caused by genetic defects that affect the body’s ability to make strong bones. Collagen is the major protein of the body’s connective tissue and is part of the framework around bones are formed. In dominant (classical) OI, a person has either too little type 1 collagen or a poor quality of type 1 collagen caused by a mutation in one of the type 1 collagen genes. In recessive OI.Read More
