		The gingival tissues apical to the crown margin are adjacent to enamel and therefore are not attached by connective tissue.
		The cementoenamel junction on the proximal surfaces of the dentition is coronal to the level of the cementoenamel junction on the facial and lingual surfaces.
		Subsequent to elevation of the facial flap, enamel apical to the carious lesions was exposed.

		The Gums (gingivœ) are composed of dense fibrous tissue, closely connected to the periosteum of the alveolar processes, and surrounding the necks of the teeth.
		There is, then, at this stage a papilla (or papillæ) which has already begun to assume somewhat the shape of the crown of the future tooth, and from which the dentin and pulp of the tooth are formed, surmounted by a dome or cap of epithelial cells from which the enamel is derived.
		Its nerves are derived from the lingual, the chorda tympani, and the sympathetic.

	Osseous & chondroid choristoma
		Extraskeletal proliferation of bone and cartilage in oral and maxillofacial soft tissues probably reflects the multipotential nature of primitive mesenchymal cells throughout the region.
		Neither cartilage nor marrow is produced by the peripheral ossifying fibroma and, by tradition, a cartilaginous choristoma of the crest of the alveolar ridge in a denture wearer is called a Cutright tumor.
		Osseous choristoma should not be confused with the dystrophic calcification so frequently found in old thrombi, hematomas and keratin-filled soft tissue cysts.

		Tissue damage is confined to the gingiva coronal to the transeptal and crestal fibers.
		Tissues that prevail and heal into a periodontal pocket or bony defect are thought to be influenced by the cells that seed and proliferate into the area (progenitor ceIls).
		During the early phases of granulation tissue formation, hyaluronic acid (one of the GAGs characterized by repeating disaccharide units of glucouronic acid and hexosamine) is a predominant component of the provisional wound extracellular matrix.

	Implant of osseous matrix in rat tibias
		Considering the histologic properties of demineralized osseous matrices and the proven quality of 98% glycerin as a conservation medium, the authors analyzed histologically the behavior of the demineralized osseous matrix obtained through slow decalcification by a solution of equal parts of formic acid and sodium citrate, conserved or not in 98% glycerin.
		The osseous matrix was obtained from rat tibias which were fixed in 10% formaldehyde for 24 h and then decalcified in a solution of equal parts of sodium citrate and formic acid for 60 days.
		However, the primary objective was to evaluate the demineralized osseous matrix regarding its biocompatibility and the behavior of the bone tissue in its presence.

		Osseous involvement almost invariably is related to primary infection and is not the result of extension from a neighboring soft tissue lesion.
		Cysts developing in the viscera are characterized by a well-developed outer host adventitial layer; those occurring in osseous tissue lack this outer layer.
		Complication of osseous involvement in echinocosccosis include pathologic fracture, secondary infection, especially with staphylococci, rupture into spinal canal with neural problems, including paraphegia, transarticular extension with osseous collapse and deformity, and intrapelvic extension with compression of adjacent structures.

	Bones
		Osseous tissue itself is made of water (about 1/4 of the bone weight), organic material (about 1/3 of the bone weight, most of which is the protein, ossein) and inorganic minerals (calcium, phosphorus, and magnesium predominate, though iron, sodium, potassium, chlorine, and fluorine are also present in small amounts).
		The compact bone tissue serves as the outer shell of the bone and serves to protect the inner core of spongy bone (trebiculae, or substantia spongiosa).
		The marrow in newborns and children is generally red, turning yellow in adults in all bones with the exceptions of upper ends of the humerus and femur and in many of the flat bones of the skull, vertebrae, ribs, sternum, and hip.

	Bony Lesions
		Fibrous Dysplasia An asymptomatic regional alteration of bone in which the normal architecture is replaced by fibrous tissue and nonfunctional trabeculae-like osseous structures; lesions may be monostotic or polyostotic, with or without associated endocrine disturbances.
		Osteogenesis Imperfecta A spectrum of diseases of bone due to a basic alteration in the formation of bone connective tissue matrix, resulting in an inability of the matrix to fully mineralize, a tendency for multiple broken bones, blue sclera of the eyes, and associated dentinogenesis imperfecta.
		Central Giant Cell Lesion An intraosseous destructive lesion of the anterior mandible and maxilla in which larger lesions expand the cortical plates, cause movement of teeth, and produce root resorption; composed of multinucleated giant cells in a background of mononuclear fibrohistiocytic cells and red blood cells.

		Osseous involvement is quite rare but ranges from classic vertebral hemangioma to calvarial angiomatosis and synovial hemangioma.
		The osseous resorption may stabilize, but there is usually little regeneration.
		Tumor-induced (oncogenic) osteomalacia can be caused by numerous osseous and soft-tissue neoplasms; however, it is most frequently associated with musculoskeletal angiomatous lesions, particularly hemangiopericytoma (75).

		In light of these statistics, it should be apparent that excision of all infected soft tissue and osseous structures followed by reconstruction of the toes and forefoot should be attempted whenever possible in the patient with diabetes.
		The underlying osseous structures are debrided until robust and free bleeding is evident from the surrounding cortices and within the medullary canal.
		This is facilitated by leaving a thin layer of adipose tissue firmly adherent to the undersurface of the dermis throughout.

		Osseous hemangiomas often have a characteristic appearance on radiographs, with coarsened vertical trabeculae in the spine, a radiating weblike trabecular pattern in the skull, or multifocal honeycomb areas of bone lysis at other sites.
		Angiomatous tissue can also diffusely infiltrate bone or soft tissue (angiomatosis) or be associated with a variety of conditions, including Maffucci syndrome, Osler-Weber-Rendu disease, Klippel-Trnaunay-Weber syndrome, Kasabach-Merritt syndrome, and Gorham disease.
		In the soft tissues, these more aggressive vascular neoplasms cannot be distinguished from one another with imaging.

	Muscular System - Tissues
		Although the major tissue type present is bone, or osseous tissue, bones also possess nervous tissue on their nerves, cartilage tissue in their articular cartilages, fibrous connective tissue lining their cavities, and muscle and epithelial tissues in their blood vessels.
		This layer of connective tissue is composed of an outer dense, fibrous collagenous layer, and an inner cellular, osteogenic layer.
		Haematopoietic tissue, or red marrow, is present within the cavities of spongy bone of long bones, and in the diploe of flat, and some irregular bones.

		According to biologists' data, chronical stress inhibits the osseous tissue maturing process and intensifies decomposition of collagen protein and proteoglycans with the animals non-resistant to stress.
		That results in inhibition of the osseous tissue growth or destruction.
		The increase of oxyproline content in the parodentium tissue allows to judge about the destruction of collagen proteins, which make the organic basis for bones.

		Avascular osteonecroses (AVNS) are nonspecific de- structions of focal skeletal areas with necrosis of medullary and osseous tissue [2,9].
		The osseous borders in the transition zone from gap to articular surfaces are either rounded (at- rophic form) or osteophytic (hypertrophic form).
		The prognostic value of fibrovascular tissue in the mid layer of lunatomalacia and within the nonunion gap of the scaphoid has to be evaluated in further MRI studies with histopathological correlation.

		Root coverage with connective tissue grafts (CTGs) can cover roots that may otherwise be restored with tooth colored materials (which may result in a longer unesthetic tooth) and restore the esthetics for the patient.
		It is important to remember that the crown must be seated on approximately 2mm of solid tooth tissue (ferrule effect) to reinforce retention and that, other than the maxillary anteriors/esthetic zone, there is no reason to place a margin subgingivally.
		Removal of excessive amounts of bone or tissue to achieve the desired result may indicate that the tooth may need to be extracted and an alternative (FPD or implant) may be indicated.

	Guided Bone Regeneration (GBR) on Healing Bone Defects: A Histological Study in Rabbits - Introduction
		If the gap surrounding an implant is large, fibrous connective tissue cells may proliferate into the area and produce a fibrous capsule around the implant.
		This method has been used in periodontal surgery to develop the attachment of periodontal connective tissue to the root surface of teeth, and to exclude epithelial cells from the wound.
		It has also been used to form improved osseous tissue around the implants in bone, to prevent fibrous encapsulation, and to produce additional bone in the area.

		This reported intensive inflammatory tissue response was associated with the use of highly crystalline self-reinforced PGA implants, which consequently led to a decrease in their clinical use.
		If the material is applied extra-articularly in soft tissue or in cancellous bone of the metaphysis, such as wrist or ankle fractures or the tibial interference screw in anterior cruciate ligament reconstruction, the debris accumulated at the implant site during degradation could be expelled into the surrounding soft tissue (Table 3, Fig 14).
