2. Effect of a novel bioceramic root canal sealer on the angiogenesis-enhancing potential of assorted human odontogenic stem cells compared with principal tricalcium silicate-based cements
Abstract Objective: This study evaluated the angiogenesis-enhancing potential of a tricalcium silicate-based mineral trioxide aggregate (ProRoot MTA), Biodentine, and a novel bioceramic root canal sealer (Well-Root ST) in human dental pulp stem cells (hDPSCs), human periodontal ligament stem cells (hPLSCs), and human tooth germ stem cells (hTGSCs). Methodo

3. Analysis of Electronic Apex Locators in Human Teeth Diagnosed With Apical Periodontitis
Resumo Os localizadores eletrônicos apicais têm sido usados para estabelecer o comprimento de trabalho no tratamento do canal radicular. Nos dentes diagnosticados com periodontite apical, a reabsorção das estruturas apicais dos dentes pode levar a dificuldades na obtenção de uma odontometria apropriada. Este estudo comparou três localizadores apicais

4. Influence of a Retentive Shoulder Design to Prevent Early Failure of Three Core Build-Ups
Resumo Este estudo avaliou a influência de um preparo retentivo em forma de ombro para prevenir a falha precoce de núcleos de preenchimento realizados em molares com 3 diferentes tipos de resina composta. Noventa e seis terceiros molares superiores hígidos extraídos de humanos, foram divididos em dois grupos (n=48) de acordo com o tipo de redução oclus

5. The use of a liner under different bulk-fill resin composites: 3D GAP formation analysis by x-ray microcomputed tomography
Abstract Gap formation of composite resin restorations is a serious shortcoming in clinical practice. Polymerization shrinkage stress exceeds the tooth-restoration bond strength, and it causes bacterial infiltration within gaps between cavity walls and the restorative material. Thus, an intermediate liner application with a low elastic modulus has been advis

6. Radiopacidade de dentes artificiais para treinamento pré-clínico de endodontia
Resumo Introdução Dentes artificiais têm sido utilizados para a prática odontológica e, segundo seus fabricantes, apresentam muita similaridade aos dentes humanos para treinamento. Objetivo Avaliar a radiopacidade de dentes endodônticos artificiais para uso em atividades de ensino e saber a percepção de docentes quanto à análise radiográfica. M

7. Influence of Cavity Dimensions on Microleakage of Two Bulk-Fill Composite Resins
Abstract Objective: To evaluate the effect of cavity dimensions on the amount of microleakage in two different types of bulk-fill composite resins. Material and Methods: Forty class II cavities were prepared in the mesial and distal surfaces of human molars without any carious lesions. The samples were divided into 4 groups (n=10): Group 1: cavities with 3

9. Comparative Evaluation of Remineralizing Potential of a Paste Containing Bioactive Glass and a Topical Cream Containing Casein Phosphopeptide-Amorphous Calcium Phosphate: An in Vitro Study
Abstract Objective: To evaluate and compare the remineralization potential of a dentifrice containing bioactive glass and a topical cream containing casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) in remineralizing artificial carious lesion on enamel. Material and Methods: Forty-five freshly extracted human permanent premolar teeth were selecte

10. Influence of photobiomodulation therapy on root development of rat molars with open apex and pulp necrosis
Abstract This study aimed to evaluate the role of photobiomodulation (PBM) in apexification and apexogenesis of necrotic rat molars with an open apex. Rat molars were exposed to the oral environment for 3 weeks. Canals were rinsed with 2.5% NaOCl and 17% EDTA, filled with antibiotic paste and sealed. After 7 days, canals were rinsed and divided into six grou

11. Isolation and characterization of a human cementocyte-like cell line, HCY-23
Abstract Cementum is the mineralized tissue covering the tooth root that functions in tooth attachment and post-eruptive adjustment of tooth position. It has been reported to be highly similar to bone in several respects but remains poorly understood in terms of development and regeneration. Here, we investigate whether cementocytes, the residing cells in ce

12. Effect of different stripping techniques on pulpal temperature: in vitro study
RESUMO Introdução: o desgaste proximal do esmalte é um procedimento clínico rotineiro utilizado na Ortodontia para se criar espaços ou equilibrar discrepâncias de tamanho dentário. Esse procedimento pode resultar em transferência de calor para a polpa, predispondo-a a mudanças histopatológicas e necrose do tecido pulpar. Objetivo: medir as mudan
