14. Crown discoloration promoted by materials used in regenerative endodontic procedures and effect of dental bleaching: spectrophotometric analysis
Abstract Regenerative endodontic procedure (REP) has been proposed as a new approach to treat immature permanent teeth. However, materials used in REP for root canal disinfection or cervical sealing may induce tooth discoloration. Objectives To assess tooth crown’s color after intracanal treatment with triple antibiotic paste (TAP) or calcium hydroxide (

15. Inflammatory response of human dental pulp to at-home and in-office tooth bleaching
ABSTRACT Tooth bleaching is a technique of choice to obtain a harmonious smile, but bleaching agents may damage the dental pulp. Objective: This study evaluated the inflammatory responses of human dental pulp after the use of two bleaching techniques. Material and Methods: Pulp samples were collected from human third molars extracted for orthodontic reason

20. In Situ and In Vitro Effects of Two Bleaching Treatments on Human Enamel Hardness
Resumo O objetivo deste estudo foi avaliar in vitro e in situ os efeitos de dois tratamentos clareadores sobre a microdureza do esmalte dental humano. Sessenta blocos de esmalte obtidos de trinta molares recentemente extraídos foram utilizados. Os espécimes foram polidos com lixas sob refrigeração com água. As amostras de esmalte foram divididas aleator

22. Effects on gastric mucosa induced by dental bleaching – an experimental study with 6% hydrogen peroxide in rats
The value of aesthetic dentistry has precipitated several developments in the investigation of dental materials related to this field. The free marketing of these products is a problem and it is subject to various interpretations regarding its legality. There are several techniques for tooth whitening, the most used one being the external bleaching. It is th
