GSK3β rephosphorylation rescues ALPL deficiency-induced impairment of odontoblastic differentiation of DPSCs.

Stem Cell Res Ther 2021 Apr 6;12(1):225. Epub 2021 Apr 6.

National & Local Joint Engineering Research Center of Biodiagnosis and Biotherapy, Precision Medicine Institute, The Second Affiliated Hospital of Xi'an Jiaotong University, No.157 Xiwu Road, Xi'an, 710004, China.

Background: Premature exfoliation of the deciduous teeth is a common manifestation in childhood patients with hypophosphatasia (HPP), which is an autosomal inherited disease caused by ALPL mutations. Dysplasia of the cementum, dentin, and alveolar bone has been proposed to be the main reasons for the exfoliation of teeth, while the extraordinarily complex intracellular mechanisms remain elusive. Dental pulp stem cells (DPSCs) have been demonstrated to successfully regenerate functional pulp-dentin-like tissue. Read More

Exploring a Chemotactic Role for EVs from Progenitor Cell Populations of Human Exfoliated Deciduous Teeth for Promoting Migration of Naïve BMSCs in Bone Repair Process.

Stem Cells Int 2021 17;2021:6681771. Epub 2021 Mar 17.

Department of Oral and Biomedical Sciences, School of Dentistry, College of Biomedical and Life Sciences, Cardiff University, Cardiff, UK.

Mobilization of naïve bone marrow mesenchymal stromal cells (BMSCs) is crucial to desired bone regeneration in both orthopedic and dental contexts. In such conditions, mesenchymal progenitor cell populations from human exfoliated deciduous teeth (SHEDs) present advantageous multipotent properties with easy accessibility which makes them a good candidate in both bone and periodontal tissue regeneration. Extracellular vesicles (EVs) are a functional membranous structure which could participate in multiple cell interactions and imitate the biological functions of their parenting cells largely.

Impact of non-restorative cavity control on proximal carious lesions of anterior primary teeth on the tooth survival and patient-centered outcomes (CEPECO 2): study protocol for a non-inferiority randomized clinical trial.

BMC Oral Health 2021 Mar 31;21(1):167. Epub 2021 Mar 31.

Graduate Program in Dentistry, Ibirapuera University, Av. Interlagos 1329, São Paulo, SP, 04661-100, Brazil.

Background: Studies have questioned the necessity of restoring cavitated carious lesion on primary teeth, once the control of biofilm is the most important factor to arrest these lesions. This randomized clinical trial aimed to compare the survival of teeth treated with a non-restorative cavity control (NRCC) compared to resin composite restorations (RCR) on proximal carious lesion in anterior primary teeth, as well as the impact of these treatments on patient-centered outcomes.

Methods: A randomized clinical trial with two parallels arms (1:1) will be conducted. Read More

The effect of fibroblast growth factor 7 on human dental pulp stem cells for differentiation to AQP5-positive and αSMA-positive cells in vitro and in vivo.

Clin Exp Dent Res 2021 Mar 30. Epub 2021 Mar 30.

Department of Pathology, Tokyo Dental College, Tokyo, Japan.

Objectives: Transplantation of stem cells into wounds has become popular in regeneration therapies. As stem cells for transplantation, human dental pulp stem cells (hDPSCs) are known to be pluripotent cells that are relatively easy to collect from the pulp of deciduous or wisdom teeth. The purpose of this study was to investigate whether hDPSCs treated with fibroblast growth factor 7 (FGF7) would contribute to the regeneration of wounded rat submandibular glands (SMGs). Read More

Associations of metals and neurodevelopment: a review of recent evidence on susceptibility factors.

Curr Epidemiol Rep 2020 Dec 30;7(4):237-262. Epub 2020 Oct 30.

Department of Environmental Health, Boston University School of Public Health, Boston, MA, USA.

Purpose Of Review: Epidemiologic evidence exists that many metals are associated with adverse neurobehavioral effects in young children, including lead (Pb), methylmercury (meHg), manganese (Mn) and arsenic (As). Importantly, chemical insult can vary depending on host factors and exposure circumstance. This systematic review summarizes the recent literature investigating modifying factors of the associations between metals and neurodevelopment, including immutable traits (sex or genetics) or exposure conditions (timing or co-exposures).

Needle phobia is an important reason to postpone a dental appointment.Needleless anaesthesia exists, but is it as effective as the conventionalmethods of dental anaesthesia? A literature review showed conclusionsto differ regarding the use of so-called jet injectors, which force a smallquantity of anaesthetic liquid through the mucosa under high pressure.According to some researchers, this technique works sufficiently wellin the deciduous dentition; this has, however, not been confirmed inall studies, nor is effectiveness guaranteed.

VEGFR1 primes a unique cohort of dental pulp stem cells for vasculogenic differentiation.

Eur Cell Mater 2021 Mar 16;41:332-344. Epub 2021 Mar 16.

Department of Cariology, Restorative Sciences and Endodontics, University of Michigan School of Dentistry, 1011 N. University Rm. G049, Ann Arbor, MI 48109-1078,

Dental pulp stem cells (DPSCs) constitute a unique group of cells endowed with multipotency, self-renewal, and capacity to regenerate the dental pulp tissue. While much has been learned about these cells in recent years, it is still unclear if each DPSC is multipotent or if unique sub-populations of DPSCs are "primed" to undergo specific differentiation paths. The purpose of the present study was to define whether a sub-population of DPSCs was uniquely primed to undergo vasculogenic differentiation. Read More

Diagnosis and treatment of dens invaginatus with open apex in a young adult patient by using cone-beam computed tomography and operative microscope.

Eur J Paediatr Dent 2021 ;22(1):15-18

Department of Surgical, Oncological and Oral Sciences, University of Palermo, Palermo, Italy.

Background: Dens invaginatus is a developmental anomaly that can affect both deciduous and permanent dentition. The anomaly is caused by the invagination of the enamel organ into the dental papilla prior to the calcification of the dental tissues. The treatment option changes according to the classification, from the simple filling of the invaginated enamel area to root canal treatment with or without retrograde surgery, intentional re-implantation, or the extraction of the affected tooth.
