Bone marrow coagulated and low-level laser therapy accelerate bone healing by enhancing angiogenesis, cell proliferation, osteoblast differentiation, and mineralization.

The present study evaluated bone marrow aspirate (BMA) and low-level laser therapy (LLLT) on bone healing. It was created critical-size defects (CSD) of 5 mm diameter in rat calvaria of 64 rats. Animals were randomly divided into four groups: Control (blood clot), BMA (coagulated BMA), LLLT (laser irradiation and blood clot), and BMA/LLLT (laser irradiation and coagulated BMA).

Topical sodium alendronate combined or not with photodynamic therapy as an adjunct to scaling and root planing: Histochemical and immunohistochemical study in rats.

Objective: The purpose of this study was to evaluate influence of topical sodium alendronate (ALN), photodynamic therapy (aPDT), or a combination thereof as adjuvant to scaling and root planing (SRP) in the treatment of experimental periodontitis in rats.

Background: Therapeutic protocols to control periodontitis progression that aim to equalize bacterial action and load with tissue immune response are well addressed in current scientific research.

Methods: Experimental periodontitis was induced in 96 rats with a ligature around the mandibular left first molar.

Effects of the prebiotic mannan oligosaccharide on the experimental periodontitis in rats.

Aim: To evaluate the effect of the prebiotic (PREB) mannan oligosaccharide (MOS) on the progression of the experimental periodontitis (EP) and intestinal morphology in rats.

Materials And Methods: Forty rats were randomly allocated into groups (n = 10): C (control), PREB, EP and EP-PREB. Groups PREB and EP-PREB received MOS incorporated into the feed daily.

Long-term therapy with intravenous zoledronate increases the number of nonattached osteoclasts.

The purpose of this study was to investigate the influence of long-term therapy with intravenous zoledronate (ZA) on the healing of extraction sockets in rats. Forty rats, divided into groups C (Control) and Z (Zoledronate), received intravenous injections of either saline solution or ZA for 24 weeks. Their right maxillary incisor was extracted.

Platelet-rich plasma derived from bone marrow aspirate promotes new cementum formation.

Background: This study evaluates the influence of platelet-rich plasma derived from bone marrow aspirate (PRP-BMA) on the healing of periodontal fenestration defects in rats.

Methods: Periodontal fenestration defects were surgically created in the mandibles of 40 rats. The animals were randomly divided into two groups, control and PRP-BMA, in which defects were filled with blood clot or PRP-bma, respectively.

Platelet-rich plasma, low-level laser therapy, or their combination promotes periodontal regeneration in fenestration defects: a preliminary in vivo study.

Background: This study histomorphometrically analyzes the influence of platelet-rich plasma (PRP), low-level laser therapy (LLLT), or their combination on the healing of periodontal fenestration defects (PFDs) in rats.

Methods: PFDs were surgically created in the mandibles of 80 rats. The animals were randomly divided into four groups: 1) C (control) and 2) PRP, defects were filled with blood clot or PRP, respectively; 3) LLLT and 4) PRP/LLLT, defects received laser irradiation, were filled with blood clot or PRP, respectively, and then irradiated again.

Bone marrow aspirate combined with low-level laser therapy: a new therapeutic approach to enhance bone healing.

This study evaluated the influence of bone marrow aspirate (BMA), low-level laser therapy (LLLT) and their combination on bone healing in surgically created critical-size defects (CSDs) in rat calvaria. 40 rats were divided into four groups: C (control), BMA, LLLT and BMA/LLLT. A 5mmdiameter CSD was created in the calvarium of each animal.
