Avaliação da ozonioterapia no tratamento da osteonecrose induzida por zoledronato em ratas senis

A ozonioterapia vem se demonstrando uma ferramenta promissora na prevenção de infecções e no auxílio da reparação tecidual, conciliando com os desafios no tratamento da osteonecrose dos maxilares induzida por medicamentos (ONM-M), este projeto objetiva analisar os efeitos da ozonioterapia, em 55 r...

Effects of salbutamol, montelukast and prednisone on orthodontic tooth movement in rats

Braz. dent. sci; 24 (2), 2021
Objective: To evaluate the effect of salbutamol, montelukast, and prednisone on orthodontic tooth movement in rats. Material and Methods: In vivo experimental preclinical study. The sample consisted of 48 rats randomly distributed in four study groups. Group A was given saline s...

Physicochemical properties and effect of bioceramic root canal filling for primary teeth on osteoblast biology

J. appl. oral sci; 29 (), 2021
Abstract Bio-C Pulpecto (Bio-CP) was recently developed as the first bioceramic root filling material for primary teeth. Objective To evaluate the physicochemical properties of radiopacity, setting time, pH, cytocompatibility and potential of Bio-CP to induce mineralisation, compared with (1) Calen thi...

Unravelling the role of chemical and mechanical modifications of titanium surfaces in osteogenic differentiation and bone formation

To increase osteoblastic differentiation and the production of mineralized tissue, chemical and structural modifications on the surface of prosthetic implants have been proposed. Studies suggest that these modifications modulate and stimulate osteoblastic differentiation and cell response. We investigate...

Osteoporosis affects functional activity and gene expression of osteoblastic cells derived from rat alveolar bone

Braz. dent. j; 31 (6), 2020
Abstract Recent studies suggest that osteoporosis, in addition to the damage caused in long bones, may cause deterioration in the jaws, especially in alveolar bone sites, with effects in the progress of periodontal disease as well as in bone healing. The aim of this study was to evaluate the effect of os...

Acciones óseas de las hormonas de la neurohipófisis
Bone actions of neuro hypophyseal hormones

Actual. osteol; 16 (2), 2020
La oxitocina (OXT) como la arginina-vasopresina (AVP) son dos hormonas primitivas secretadas por la hipófisis posterior. Sus receptores están mucho más ampliamente distribuidos en el organismo de lo que se pensaba originalmente, incluido el hueso. En los estudios preclínicos, la OXT ha mostrado ser a...

Influence of bisphosphonates on the behavior of osteoblasts seeded onto titanium discs

Braz. dent. j; 31 (3), 2020
Abstract Among other factors, types of bisphosphonates and treatment regimens seem to be strongly associated with the success or failure of installation of osseointegrated implants. This study investigated the influence of two bisphosphonates, sodium alendronate (SA) and zoledronic acid (ZA), on the meta...

lncRNA TUG1 promotes proliferation and differentiation of osteoblasts by regulating the miR-545-3p/CNR2 axis

Braz. j. med. biol. res; 53 (11), 2020
Osteoblast differentiation is an effective way to promote bone formation. Long non-coding RNA taurine upregulated 1 (TUG1) has been identified as a crucial modulator of multiple biological processes. This study was designed to investigate the function of TUG1 in the proliferation and differentiation of o...

Transcriptome profile of highly osteoblastic/cementoblastic periodontal ligament cell clones

J. appl. oral sci; 28 (), 2020
Abstract Heterogeneous cell populations of osteo/cementoblastic (O/C) or fibroblastic phenotypes constitute the periodontal dental ligament (PDL). A better understanding of these PDL cell subpopulations is essential to propose regenerative approaches based on a sound biological rationale. Objective Our...
