Introduction: Tooth bleaching is a procedure very requested in dental offices, stimulating constant research for new products and technologies. This study aimed to evaluated in vitro the color change of tooth enamel bleached with violet LED associated or not with hydrogen peroxide gel. Methods: 48 fragments of bovine teeth (n=12), were sectioned (5x5x3 mm), flattened, and polished. The specimens were stained in 20ml of coffee, which was replaced every 24h for 7 days. The experimental groups...
Brazilian dentistry is the best in the world!” This great slogan speaks volumes about ourselves and our prideful identity. The correlation I make is: “Brazilian football is the best in the world!” Would you agree or disagree?
In this edition of the Highlights section, we will address a fundamentally important topic about adhesive and restorative procedures sucess, the Photopolymerization. We are a dependent “LED” generation, since most of the procedures that we commonly perform, regardless of the clinical area, depends on some type of light source for the polymerization of materials.
Ceramic laminated veneers (CLV) are ultraconservative indirect aesthetic restorations that requires minimal or no enamel preparation with minimum thickness (ranging from 0.2 to 0.5 mm). They are capable of reproducing the aspects of the natural teeth and their clinical longevity is greatly determined by the bond strength formed among the triad: tooth surface, luting cement and porcelain veneers. Therefore, this clinical case reports the replacements of unsatisfactory ceramic laminates after...
Power, emission spectrum and light beam profile are important factors related to the light emitted by light curing units and must be considered when choosing a light curing unit.1 Besides that, there are equipment made with different materials, shapes and sizes. Therefore, one should also consider factors related to the equipment’s design: shape/angle and size of the light tips.
Fixed partial dentures represent an alternative for oral rehabilitation, combining aesthetics and function. The need for better mechanical properties of ceramic materials led to the introduction of zirconia in Dentistry. The objective of this study was to present a clinical case of oral rehabilitation with single and multiple anterior and posterior fixed prostheses, demonstrating the applicability of zirconia as an aesthetic, functional and resistant material for infrastructure and...
“Today, I’m going to promote to an important agenda. I’m not gonna give voice to it, because it already has one and it’s powerful. The column in this issue is not signed by me: let’s talk about a white dentistry. Read it calmly because there are syllables, words, that will echo in you.” (Felipe Rossi)
Introduction: The aim of this in vitro study was to evaluate the interference of three beverages (coffee, Coca-Cola® and red wine) in the color of resin composites: Transbond XT®, Orthocem®, Fill Magic® and Z100®. Methods: The sample was made up of 160 test specimens (n=10), with a total of 40 for each composite. During the experimental period of 28 days, the test specimens were immersed in distilled water and kept in an oven at 37° C. The experimental groups were immersed in coffee,...
In the midst of a never-before experienced situation, the covid-19 pandemic, an unprecedented event, has been observed in Dentistry: the additional pandemic of Instagram live streams. Such an unusual and, at the same time, fantastic phenomenon has led to an avalanche of rather pertinent, well-grounded and free information, which has certainly helped many colleagues have a better understanding of several conditions and facts associated with our profession. I participated in some streams about...
Dental agenesis, especially of maxillary lateral incisors, is the most common type of disturbances of teeth. Most of the time, it causes the disharmony of the smile and causes patient dissatisfaction. In addition, it requires multidisciplinary planning to define the best treatment option, aiming at a good aesthetic and functional result. The purpose of this clinical case is to report the multidisciplinary approach in a case of reanatomization of canines with ceramic veneers in a patient with...
In times of physical distancing and changes in our routines, such as the postponement of the Meeting of the Brazilian Group of Dental Materials, we must reflect on some crucial points of our research activity. More specifically, in Dental Materials research, it is important to reflect where we should make efforts to advance science in the area.
Introduction: Composite resins are operatordependent materials and hence LED-dependent. There are many types of LEDs available on the market, so knowledge of emitted irradiance and equipment components is critical to maintaining the quality of adhesive restorations. The lightconducting tip, depending on the curing light, may be transparent or dark and may change the radiance of the device when in contact with impurities, when cracked and / or fractured. Objective: To evaluate the curing tips...
The goal for the Zeal project was to communicate our values in the environment. The word zeal in Portuguese is zelo which according to the Online Portuguese Dictionary means: “Great care and concern that is dedicated to someone or something.” The environment should translate welcome, empathy, security and care.
Darkened anterior teeth compromise smile aesthetics, so rehabilitating them aesthetically and functionally has become one of the biggest clinical challenges for the dental surgeon. The development of adhesive dentistry, associated with the ability of dental ceramics to condition, guaranteeing the high quality of the bonding of these materials to the dental tissues, has made the treatment with ceramic laminates have high satisfaction rates, not only due to the natural optical characteristics...
Supernumerary cusps are rarely explored clinically or recorded. Lack of knowledge about them is why professionals and patients, in special, do not give them the importance that their correction and adaptation should receive. The presence of a supernumerary cusp should be disclosed to the patient, and its importance should be stressed. In special, attention should be drawn to the treatment required to manage and correct this anomaly, whether its consequences are esthetic or functional. The...
The world will not be the same after the pandemic” has been the most shared post in social networks and chats between friends and family. Some philosophers, based on the many crises recorded in history as a reference, do not believe in significant behavioral changes that last after a crisis is over.
