Chitosan is a natural polymer that can sustain not only osteoblast adhesion and proliferation for bone regeneration purposes, but it also claimed to exhibit antibacterial properties towards several Gram-positive Gram-negative bacteria. In this study, chitosan was modified with sodium hyaluronate, crosslinked polyethylene glycol diglycidyl ether (PEGDE) both cytotoxicity behavior studied. The presence of hyaluronate PEGDE on detected by FTIR, XRD, XPS. (CHT) films showed better thermal...

It has been reported that chitosan scaffolds, due to their physicochemical properties, stimulate cell proliferation in different tissues of the human body. This study aimed determine physicochemical, mechanical, and biological properties scaffolds crosslinked with ammonium hydroxide, pH values, better understand behavior depending on biomaterial. Scaffolds were either neutralized sodium hydroxide solution, washed distilled water until reaching a neutral pH, or kept at alkaline pH....

Dental tissue-derived mesenchymal stem cells (DT-MSCs) are a promising resource for tissue regeneration due to their multilineage potential. Despite accumulating data regarding the biology and differentiation potential of DT-MSCs, few studies have investigated adipogenic capacity. In this study, we features dental pulp (DPSCs), as well in vitro effects different media on these cells, compared them those periodontal ligament (PLSCs) follicle (DFSCs). DFSC, PLSCs, DPSCs exhibit similar...

Introduction Propolis has been used traditionally for different human diseases and even recently as dental biomaterials because of its antibacterial, antimycotic, anti-inflammatory properties. However, a proper correlation between in vitro vivo properties not clearly established. Methods The composition propolis was determined by high-performance liquid chromatography–ultraviolet mass spectrometry (HPLC-UV-MS). Viability ethanolic solution evaluated thiazolyl blue tetrazolium bromide (MTT)...

Obesity is a significant health concern that has reached alarming proportions worldwide. The overconsumption of high-energy foods may cause metabolic dysfunction and promote the generation new adipocytes by contributing to several obesity-related diseases. Such concerns demand deeper understanding origin if we want develop therapeutic approaches. Recent findings indicate adipocyte development facilitated tight epigenetic reprogramming, which required activate gene program change fate...

To determine any associations between obesity and caries activity in the mixed dentition stage among primary school children a low-income Mexican school.

Background: We assessed the effect of propolis on antibacterial, mechanical, and adhesive properties a commercial poly(alkenoate) cement. Methods: The cement was modified with various concentrations propolis, antibacterial assays were performed against S. mutans by both MTT agar diffusion tests. compressive, flexural, also evaluated. Results: showed activity in assays, although reductions compressive (from 211.21 to 59.3 MPa) flexural strength 11.1 6.2 noted addition while (shear bond novel...

Dental pulp (DP) represents an accessible and valuable source promising of stem cells for clinical application. However, there are some disadvantages associated with the isolation dental (DPSCs), which include size weight tissue needed to yield sufficient culturing in vitro. Therefore, objective this study was compare vitro histomorphometry DP from permanent (premolars, third molar), supernumerary deciduous teeth patients between 5 25 years old regards weight, length, width cell density four...

Antecedentes: la caries de infancia temprana es una enfermedad bacteriana que se presenta en niños menores 71 meses edad, con prevalencia puede llegar hasta 90% poblaciones altamente vulnerables. Objetivo: determinar y los factores riesgo pacientes 48 meses, así como relación existente entre las caries. Materiales métodos: estudio descriptivo transversal el incluyeron 63 sin distinción género, desde 9 edad (edad promedio 26.8 meses). Se utilizó un cuestio- nario registraron para efectuó...

Biomaterials and stem cells are essential components in the field of regenerative medicine. Various biomaterials have been designed that appropriate biochemical biophysical characteristics to mimic microenvironment an extracellular matrix. Dental (DT-MSCs) represent a novel source for development autologous therapies due their easy availability. Although research on DT-MSCs has progressed, there still challenges molecular mechanisms involved regulating behavior DT-MSCs. In this review,...

This study's objective was to compare the total and outside cleft prevalence of dental anomalies (DA) between patients with lip palate (CLP) a control group. retrospective cross-sectional study done under case-control design. The case group consisted 192 non-syndromic complete CLP, while included 411 patients. All subjects had orthopantomography, intra, extraoral photographs. agenesis, supernumerary teeth, impacted transposition, microdontia were compared using chi-squared test (P < .05)....

Dental stem cells (DSCs) are multipotent with high proliferation capacity and multilineage differentiation. Few studies have compared the cellular characteristics adipogenic differentiation potential of DSCs derived from tissues same individual. The objective this work was to evaluate differences in growth characteristics, expression mesenchymal (MSCs)-specific markers,&#x0D; proteomic profile response differentiation, dental pulp periodontal ligament obtained a single donor. were isolated...

The present study aimed to determine the genetic variants of PAX9, MSX1, and AXIN2 in Mayan probands with non-syndromic dental agenesis (NSDA) from Yucatan, Mexico. We sequenced DNA specific exons genes by using Sanger method seven familial NSDA attending orthodontic clinics Merida, bioinformatically analyzed four genomes unaffected people ancestry for comparative purposes. Two had oligodontia (14 or 16 missing teeth) five hypodontia (1-2 teeth). found following variants: rs8670 MSX1;...

Non-formation of a tooth impacts the morphology alveolar bone, which may, in turn, generate an imbalance facial growth. This retrospective case-control study aimed to determine whether observable differences exist growth patients with dental agenesis relative complete dentition controls.The sample comprised 75 agenesis, and each case was paired two controls same age gender (n = 150). All were measured cephalometrically (31 variables), both groups compared student's t- or Z-test (P < 0.05)....
