Effect of local administration of injectable platelet-rich fibrin on root resorption during orthodontic tooth movement in dogs.

Background: This study aimed to assess the effect of local administration of injectable platelet-rich fibrin (i-PRF) on root resorption during orthodontic tooth movement in dogs.

Materials And Methods: This animal study was conducted on 4 adult male mongrel dogs. The right and left maxillary first premolars of the dogs were extracted, and a Nickel-Titanium closed coil spring was used to connect the canine to the second premolar with 150 g load.

Effect of local injection of injectable platelet-rich fibrin on bone remodeling during orthodontic tooth movement in dogs.

Background: This study aimed to assess the effect of local injection of injectable platelet-rich fibrin (i-PRF) on bone remodeling during orthodontic tooth movement in dogs.

Materials And Methods: In this animal study, the maxillary first premolars of four adult male mixed-breed dogs were bilaterally extracted, and a nickel-titanium closed coil spring with 150 g force was placed between the canine and second premolar teeth. One quadrant of the maxilla was randomly selected as the test quadrant, and 0.

The effect of laser irradiation and doxycycline application on the production of matrix metalloproteinase-8 and collagen I from cultured human periodontal ligament cells.

Background: Periodontal ligament fibroblasts (PDLF) play a key role in periodontal wound healing and tooth-supporting structures. Various approaches have been tried to enhance the fibroblastic activity such as laser irradiation or doxycycline application. The current study explored the influence of laser irradiation and doxycycline application on human PDLF.
