Granuloma
A reactive nodule consisting of modified macrophages resembling epithelial cells surrounded by a rim of mononuclear cells, usually lymphocytes, and often containing giant cells. A relatively small nodular inflammatory lesion containing grouped mononuclear phagocytes, caused by infectious and noninfectious agents. One of a variety of growths of inflamed, granular-appearing tissue. Infiltration of tissue phagocytes, producing…

Granulation tissue
Healing tissue that forms in response to any injury or surgical insult of soft tissue and consists of fibroblasts, capillary buds, inflammatory cells, and edema. A mixture of proteins and cells produced by the fibroblast growth that results from a wound. A growth of young capillaries and fibrous tissue cells which is the basis for…

Gram positive
Pertaining to bacteria that stain deep purple with Gram stain. These bacteria have a thick peptidoglycan layer but no lipopolysaccharide in their cell walls. Retaining the stain or resisting decolorization by alcohol in Gram’s method of staining, a primary characteristic of bacteria whose cell wall is composed of a thick layer of peptidologlycan with attached…

Gram negative
Pertaining to bacteria that counterstain pale red with Gram stain. These bacteria have a lipopolysaccharide (endotoxin) layer exterior to a thin peptidoglycan layer in the cell walls. Losing the stain or decolorized by alcohol in Gram’s method of staining, a primary characteristic of bacteria having a cell wall composed of a thin layer of peptidoglycan…

Grafting material
A substance, natural or synthetic, used to enhance or repair a tissue defect or deficiency.

Graft healing
The restoration of implanted living tissue to its original integrity. Bone graft healing has two different routes: either it fails to incorporate and gradually disappears, or it becomes incorporated as a mechanically functioning part of the host bone. Osteoblasts or osteoprogenitor cells may be transferred to the recipient site. Via resorption of bone graft, various…

Graft consolidation (bone)
The vascularization and integration at the cellular level of a graft with its recipient site. It involves the formation of a graft‐woven bone complex that remodels into lamellar bone and further adapts based on loading.
-
Xenograft
A surgical graft of tissue from one species to an unlike species. The cells of one species transplanted to another species. Tissue graft from one species to an unrelated species. Heterogeneous graft. Grafting material harvested from different species from that of the recipient. Tissue taken from an individual of one species and grafted on an…

Soft tissue (gingival) graft
An autogenous graft of masticatory mucosa or collagenous tissue completely or partially detached from its original site and placed in a prepared recipient bed.
-
Isograft
A graft between genetically identical individuals, usually between identical twins. Isogeneic graft, isologous graft, syngeneic graft. A tissue graft transplanted from one genetically identical individual to another, as in monozygotic twins. Graft taken from another individual or animal of the same genotype (genetic information) as the recipient; sometimes called autograft. A graft of tissue from…
