13. Microbial Reduction by Two Chemical-Mechanical Protocols in Primary Teeth with Pulp Necrosis and Periradicular Lesion - An In Vivo Study
O objetivo deste estudo foi determinar a eficácia das manobras químico-mecânicas de dois protocolos endodônticos, na redução do conteúdo séptico de canais radiculares de dentes decíduos com polpa necrosada e lesão perirradicular. Vinte e quatro canais radiculares decíduos com necrose pulpar e lesão perirradicular foram divididos em dois grupos de

14. 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

15. 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

16. 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

17. 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

18. 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

19. The cytotoxicity of methacryloxylethyl cetyl ammonium chloride, a cationic antibacterial monomer, is related to oxidative stress and the intrinsic mitochondrial apoptotic pathway
Antibacterial monomers incorporated in dentin bonding systems may have toxic effects on the pulp. Thus, the cytotoxicity of antibacterial monomers and its underlying mechanisms must be elucidated to improve the safety of antibacterial monomer application. The influence of an antibacterial monomer, methacryloxylethyl cetyl ammonium chloride (DMAE-CB), on the

20. Synergistic growth effect among bacteria recovered from root canal infections
The objective of this study was to determine the ecological relationships between bacterial species that colonize infected root canals. Root canal bacteria recovered from one patient with pulp canal necrosis were evaluated in vitro for synergistic and antagonistic activities determined by mono and co-culture growth kinetics and the production of bacteriocin-

21. 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

22. Estudo do hidrÃxido de cÃlcio associado ou nÃo à clorexidina como medicaÃÃo intracanal de dentes permanentes necrosados / Study of calcium hydroxide associated or not to chlorhexidine as intracanal medication in necrotic teeth
Aware that the main objective of endodontic treatment is the removal of microorganisms and the prevention of re-infection inside the root canal, and that the infections are polymicrobial and difficult to eliminate, the biomechanical preparation is essential for disinfection, though it is unable to eradicate all microorganisms. The intracanal medication is us

The goals of this dissertation are study of sodium hypochlorite and chlorhexidine as irrigants, through a literature review, evaluate and quantify, by means of bacterial culture, the antibacterial effect of biomechanical preparation and pulp-based hydroxide calcium with or without 1% chlorhexidine on bacteria in root canals of permanent teeth after necrotic

24. Lipopolysaccharide-induced dental pulp cell apoptosis and the expression of Bax and Bcl-2 in vitro
Lipopolysaccharide exerts many effects on many cell lines, including cytokine secretion, and cell apoptosis and necrosis. We investigated the in vitro effects of lipopolysaccharide on apoptosis of cultured human dental pulp cells and the expression of Bcl-2 and Bax. Dental pulp cells showed morphologies typical of apoptosis after exposure to lipopolysacchari
