Comparative study of demineralized freeze-dried bone allograft and its combination with platelet-rich fibrin in the treatment of intrabony defects: A randomized clinical trial.

Background: The clinical and radiographic efficacy of bone grafts and biomaterials, such as platelet-rich plasma and platelet-rich fibrin (PRF), for reconstructing lost periodontal structures has been well documented. However, there is limited data regarding the presence of demineralized freeze-dried bone allograft (DFDBA) in an environment with abundant growth factors provided by platelet concentrates.

Objectives: The aim of the study was to compare the clinical and radiographic effectiveness of DFDBA with PRF versus DFDBA alone in the treatment of intrabony defects.

Scanning electron microscopy study to evaluate and compare fibrin clot adhesion over the root surface treated with tetracycline, doxycycline and minocycline.

Background: Periodontitis is an inflammatory disease caused by a group of specific microorganisms that provoke the destruction of the periodontal ligament and the alveolar bone, along with pocket formation or recession, or both.

Objectives: The present study aimed to compare the efficacy of tetracycline, doxycycline and minocycline in improving fibrin clot adhesion over manually instrumented periodontally affected root surfaces with the use of scanning electron microscopy (SEM).

Material And Methods: A total of 45 single-rooted extracted teeth were sectioned into 45 dentinal blocks and divided into 3 groups: tetracycline (group I); doxycycline (group II); and minocycline (group III).

Comparative evaluation of diode laser alone and in combination with desensitizing toothpaste in occlusion of dentinal tubules - A SEM study.

Background: In regular dental practice, dentinal hypersensitivity is a common oral condition affecting the adult population. Although a variety of treatment procedures are available, there is no single method that proved to be potent in eliminating dentine hypersensitivity and providing patients with complete relief. Hence the present study performed to estimate the occlusion of dentinal tubules using a diode laser alone and in combination with various desensitizing toothpaste, using the scanning electron microscope.
