Objective: The restoration of vital teeth with extensive loss of coronal structure is a challenge for modern dentistry. The most common treatment for this type of case is the use of mechanical retention through the use of intraradicular retainers such as glass fiber posts after endodontic therapy, followed by the fabrication of an indirect restoration. However, more recent approaches have proposed more conservative treatments, due to advances in Adhesive Dentistry combined with the use of...
I have been thinking a lot about the current Dentistry: at what point we have lost control over the limits of marketing (always travesty of market freedom, influencing not only patients, but also impressionable young odontologists); and when we lost the notion of the professional/ patient relationship, in which we would seek not what he wants, but what he needs.
In this new edition of the Highlights section, we will address a novelty theme in terms of restorative techniques. Information was sought regarding composite resin restorations using the semi-direct technique.
For many years, adhesives systems have been classified into “generations” in order to systematize the different components (e.g. etchant, primer, and adhesive) of all classes of products. However, the use of such a classification, which is based on adhesive generations, cannot be universally accepted. Moreover, since a great number of new materials are created every year, this type of classification has become rather clumsy and confusing. Therefore, nowadays contemporary adhesives are...
Objective: Intraoral scanner impressions are already present for many clinicians. The positive and pleasant patients experience takes special relevance in contemporary dentistry. The purpose of this systematic review was to analyze whether there are any differences in relation to comfort, satisfaction, and preference when patients at the dental office are receiving conventional impressions or digital impressions. Methods: a bibliographic search was carried out in Medline, Embase, Web of...
Aft er understanding the importance of light curing units and the infl uence of their characteristics on the photoactivation, it is possible to discuss factors related to the operator’s technique that are relevant during light curing
Introduction: Characterized by involuntary acts of clenching or grinding the teeth, bruxism can cause severe tooth wear. Despite being a challenging situation, the combination of conservative preparations, adhesive materials and acid-sensitive ceramics, minimally invasive ceramic restorations have been proposed as one of the rehabilitative options for patient with bruxism. The objective of this clinical case is to demonstrate the multidisciplinary esthetic-functional resolution of a patient...
The word convinces and the example drags. Where are we taking an entire generation of dentists? For many, especially young people, graduates or not, social networks have been an inspiration.
Introduction: The filling core associated with the fiberglass pins, appeared to meet the aesthetic demand and provide better distribution of chewing loads in the root, bone and periodontium, minimizing the rate of root fractures. Objective: Thus, the objective of this study was to present a clinical case report of rehabilitation of endodontically treated teeth, using a direct intra-radicular retainer, made with fiberglass pins (FGP), anatomically individualized with composite resin and,...
Social networks have become a means of communication for the rapid spread of fake news. Never before has there been so much discussion about fl at earth, anti-vaccine movement and the harmful of the mango-milk combination (If my grandmother had Facebook!). In Dentistry, amalgam has returned to being a villain wanted and severely defeated. Fluoride, which was once the protagonist of the “Communist Conspiracy” and surfed the wave of thyroid cancer as well as toxic waste, now impairs the...
Introduction: Acrylic resins have been clinically utilized for many years in dental prostheses. Advancements in computer- aided design/computer-aided manufacturing (CAD/CAM) materials and recent developments in nanotechnology have enabled the use of graphene as reinforcement phase in polymethyl methacrylate (PMMA) for CAD/CAM restorations with promising results. Material and Methods: 96 samples from monochrome G-CAM discs (G-MONO) and multichrome G-CAM discs (G-MULTI) were equally divided...
The main challenge of the architectural project, for the clinic to meet the needs of the owners, was to unite three main factors: the unevenness of the land, solar orientation and the beautiful view of Lake Aratimbó, one of the most beautiful landscapes of Umuarama, a city located in the northwest of Paraná.
Objective: to evaluate, in vitro, the effect of calcium-supplemented bleaching gels on enamel at initial stage of erosion regarding the bleaching efficacy and surface microhardness. Materials and Methods: Bovine specimens (4x4mm) were randomized into 5 groups (n=12): G1 - without bleaching (control group), G2 - 35% hydrogen peroxide (HP) without calcium, G3 - 35% HP with calcium, G4 - 7.5% HP without calcium and G5 - 7.5% HP with calcium. The specimens were stained with black tea solution...
Life is a balance between choices and opportunities. All the time we are put in situations where we need to choose one way or another, not always certain that we are getting to a place we really belong. It was with that uncertainty about the future that I, by my own choice, became a specialist and then got a Master’s Degree on Operative Dentistry. But after all, what does it mean to be a “Master of Science” nowadays? What is interesting about pursuing an academic career on a country so...
I hope you are well! For new readers, our column deals with showing clinical cases via Instagram posts, through which we were able to expose the clinical reality of direct restorations with restorative fl ows. I hope you enjoy reading and seeing the cases, manage to get something good for your clinical routine. These cases were not manipulated in an image treatment soft ware and show reality, with twin fl ash photographs and a soft box studio, but with no att empt to deceive a colleague or...
