1. TNF-alpha increases angiogenic potential in a co-culture system of dental pulp cells and endothelial cells
Abstract We recently demonstrated that a co-culture system of human umbilical vein endothelial cells (HUVECs) and human dental pulp stem cells (hDPSCs) could enhance angiogenesis ability in vitro. However, whether tumor necrosis factor α (TNF-α) could promote blood vessel formation during pulp regeneration remained unknown. The aim of this study was to inv

2. 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

3. Pulp canal obliteration after traumatic injuries in permanent teeth – scientific fact or fiction?
Abstract: Pulp canal obliteration (PCO) is a frequent finding associated with pulpal revascularization after luxation injuries of young permanent teeth. The underlying mechanisms of PCO are still unclear, and no experimental scientific evidence is available, except the results of a single histopathological study. The lack of sound knowledge concerning this p

4. Effects of Syzygium aromaticum, Cinnamomum zeylanicum, and Salvia triloba extracts on proliferation and differentiation of dental pulp stem cells
Abstract Hypersensitivity, local irritative and cytotoxic effects are known for the chemical components of Syzygium aromaticum and Cinnamomum zeylanicum contained in dental materials. However, there is no intimate data in dentistry using the whole extracts of these plants and introducing new ones. Salvia triloba is a well-known anti-inflammatory plant that c

5. Low-intensity laser phototherapy enhances the proliferation of dental pulp stem cells under nutritional deficiency
Abstract Dental trauma in immature permanent teeth can damage pulp vascularization, which leads to necrosis and cessation of apexogenesis. Studies on tissue engineering using stem cells from human exfoliated deciduous teeth (SHEDs) have yielded promising results. Laser phototherapy (LPT) is able to influence the proliferation and differentiation of these cel

6. Non-linear indices of heart rate variability during endodontic treatment
Abstract Dental treatment promotes psychosomatic change that can influence the procedure and compromise the general well-being of the patient. In this context, it highlights the importance of evaluating the function of the autonomic nervous system in individuals undergoing endodontic treatment. Thus, this manuscript aimed to analyse cardiac autonomic modulat

7. Inflammatory effect of green propolis on dental pulp in rats
Pulpotomy in deciduous teeth is a controversial issue, especially with regard to alternative materials used for the direct pulp capping of the root canal pulp tissue. The aim of the present study was to perform a histological analysis of the initial reaction of the root canal pulp tissue in rats, following pulpotomy and pulp capping with (1) green propolis e

8. Apexification with white MTA in an immature permanent tooth with dens invaginatus
Dens invaginatus, also known as "dens in dente", is a developmental dental anomaly resulting in an invagination of the enamel organ into the dental papilla. These cases present technical difficulties to the root canal treatment. Apexification using an apical plug of mineral trioxide aggregate (MTA) has been indicated as an alternative to long-term intracanal

9. AVALIAÇÃO DAS DIFERENTES TÉCNICAS DE CLAREAMENTO DENTAL DE CONSULTÓRIO: EFETIVIDADE, SENSIBILIDADE PÓS-TRATAMENTO E EFEITOS SOBRE O COMPLEXO DENTINO-PULPAR / Assessment of different in-office tooth bleaching techniques: Effectiveness, sensitivity post-treatment and effects on the pulp-dentin complex
The use of bleaching gels with low hydrogen peroxide (HP) concentration, as well as the reduction of application times or its association with calcium-containing agents may be clinical approaches to reduce the amount of HP that reaches the pulp tissue to cause local damage. However, only a few data have been published about the pulp response of human teeth s

10. Effects of bleaching agents and adhesive systems in dental pulp: a literature review
The dental pulp may be exposed to several irritants that are potentially noxious to the health and functions of this tissue. Each type of irritant or injury has different effects on the pulp, which are generally characterized by acute inflammation, chronic inflammation or necrosis. Common examples of irritants are dental caries, cavity preparation procedures

11. Avaliação histológica e imunolocalização de STRO-1 e BMP-4 em molares de ratos com polpa vital ou necrose pulpar induzida durante o desenvolvimento radicular
Objective: the aim of this study was to characterize the features of live and necrotic dental pulps of molar teeth in rats with developing roots, and to assess the expression of STRO-1 and BMP-4. Methods: twenty-four 4-month-old male Wistar rats were used. To induce necrosis, the pulps of the first lower left molars were exposed to the oral environment. The

12. Tratamento de lesões profundas de cárie : um ensaio clínico randomizado comparando tratamento expectante com remoção parcial da dentina
This randomized multicenter clinical trial evaluated the effectiveness of an alternative treatment on deep caries lesion¿s compared to stepwise excavation (SW) after three years follow up. Treatment consisted on partial caries removal (PDR) followed by tooth¿s restoration in one session. Methods: Inclusion criteria were: patients with permanent molars pres
