The purpose of this article is to study the effect on the healing of immediate replanted teeth after the biological characters of roots were changed by using exogenous fibronectin (Fn). Two adult rhesus monkeys were chosen in the experiment. Upper-incisors of each monkey were extracted. The teeth of experimental group were extracted the roots treated by 0.5 mg/ml Fn solution and replanted immediately. The roots of another animal were used as controls. After operations, the experimental specimens of 4 weeks and 8 weeks were examed histologically by light microscope and studied quantitatively by computer image analysis system. The results reveal that Fn can enhance periodontal healing by improving periodontal reattachment and reducing root resorption of replanted tooth. Fn has also the function to reduce inflammatory reactions significantly during the healing process.

D005353 Fibronectins Glycoproteins found on the surfaces of cells, particularly in fibrillar structures. The proteins are lost or reduced when these cells undergo viral or chemical transformation. They are highly susceptible to proteolysis and are substrates for activated blood coagulation factor VIII. The forms present in plasma are called cold-insoluble globulins.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012391 Root Resorption Resorption in which cementum or dentin is lost from the root of a tooth owing to cementoclastic or osteoclastic activity in conditions such as trauma of occlusion or neoplasms. (Dorland, 27th ed) Resorption, Root,Resorptions, Root,Root Resorptions

D014092 Tooth Root The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots.
