Do orthodontic movements of traumatized teeth induce dental pulp necrosis? A systematic review

Clinical Oral Investigations, 2023
Usually, orthodontic movements encompass children and young adult patients, which are more susceptible to the occurrence of traumatic dental injuries. It is necessary to understand whether the effects of orthodontic movements on traumatized teeth could induce pulp necrosis.

Dental Pulp Necrosis as a Rare Complication of Reduction Malarplasty

Journal of Craniofacial Surgery, 2007
Reduction malarplasty through the intraoral or the combined approach using intraoral and preauricular incisions is widely performed as an aesthetic surgical procedure in northeast Asia. The authors recently examined a patient who underwent this type of surgery and presented with discoloration of both upper canine teeth that was diagnosed as pulp ...

Detection of Tumor Necrosis Factor α in Normal and Inflamed Human Dental Pulps

Archives of Medical Research, 2002
The aim of this study was to determine concentrations of tumor necrosis factor-alpha (TNF-alpha) in normal, painful, and asymptomatic human dental pulps.Pulps were obtained from three groups of teeth, including healthy teeth, asymptomatic teeth with caries and/or large restoration, and symptomatic teeth with clinical diagnosis of irreversible pulpitis.

Characterization of a programmed necrosis process in 3‐dimensional cultures of dental pulp fibroblasts

International Endodontic Journal, 2012
AbstractAimTo analyse and compare the expression of nemosis markers in human lung and dental pulp fibroblasts and to determine whether this process differs by the type of mesenchymal cell.MethodsHuman dental pulp fibroblasts were obtained from unerupted third molars. Sound lung and pulpal fibroblasts were cultured in vitro as spheroids to determine the

RAC1 regulate tumor necrosis factor‐α‐mediated impaired osteogenic differentiation of dental pulp stem cells

Development, Growth & Differentiation, 2015
Human dental pulp contains a rapidly proliferative subpopulation of precursor cells termed dental pulp stem cells (DPSCs) that show self‐renewal and multilineage differentiation, including neurogenic, chondrogenic, osteogenic and adipogenic. We previously reported that tomuor necrosis factor‐α (TNF‐α) (10 ng/mL) triggered osteogenic differentiation of ...

General Control Nonrepressed Protein 5 Modulates Odontogenic Differentiation Through NF-κB Pathway in Tumor Necrosis Factor-α-Mediated Impaired Human Dental Pulp Stem Cells

Cellular Reprogramming, 2022
Dental pulp stem cells (DPSCs) from pulpitis patients showed defective osteogenic differentiation. However, as the most well-studied histone acetyltransferase, the impaired general control nonrepressed protein 5 (GCN5) plays essential roles in various developmental processes.

Hypoxia‐inducible factor 1α promotes interleukin 1β and tumour necrosis factor α expression in lipopolysaccharide‐stimulated human dental pulp cells

International Endodontic Journal, 2020
AbstractAimTo elucidate the role of HIF1α in pro‐inflammatory cytokine mRNA expression from lipopolysaccharide (LPS)‐stimulated human dental pulp cells (hDPCs).MethodologymRNA expression of interleukin (IL) 1β and tumour necrosis factor (TNF) α in LPS‐stimulated hDPCs was determined by quantitative RT‐PCR.

Early detection of pulp necrosis and dental vitality after traumatic dental injuries in children and adolescents by 3-Tesla magnetic resonance imaging

Journal of Cranio-Maxillofacial Surgery, 2015
More than 50% of all children suffer a traumatic dental injury (TDI) during childhood. In many cases, dentists apply root canal treatment (RCT), which is performed on an average of 7-10 days after replantation. Our aim was to evaluate whether RCT is necessary in many cases, and whether revitalization of affected teeth is possible and measurable by ...

Neuropeptides stimulate production of interleukin-1�, interleukin-6, and tumor necrosis factor-a in human dental pulp cells

Inflammation Research, 2004
Orthodontic tooth movement causes inflammatory reactions in the periodontal membrane and dental pulp. It has been reported that substance P (SP) and calcitonin gene-related peptide (CGRP), both sensory neuropeptides, are manifested in the dental pulp of rats during experimental tooth movement, suggesting that they might be involved in the dental pulp ...
