I HAD DONE AN EDITORIAL FOR THIS NUMBER, but, in the face of everything we saw and faced, I decided to write another one. I hope that you reflect on this text.

The question of esthetics is a major concern in dentistry today. The color of the teeth is an important factor, since the color harmony is perceived quickly. The single discoloured tooth can be a challenge in obtaining an aesthetic outcome in the anterior region. This case report describes the treatment of a single darkened tooth by combining internal and external bleaching techniques. It is also reported the clinical and radiographic follow-up in which a slight yellowing of the endodontically...

Introduction: This is the fifty of six articles which present a general view about composite resins in the last 10 years. Composite resins were created with the aim of restoring damaged tooth structures, improving function and esthetic of a smile. Despite of their excellent mechanical properties, composites are exposed to different processes of aging in the oral cavity, which can decrease the longevity of the restorations. The aim of this study was to synthesize and describe the main factors...

CONTINUANDO COM O OBJETIVO DE ABORDAR os principais temas da Odontologia atual, baseando- se em evidências para a construção das opiniões, realizou-se uma abordagem nos artigos que discutem os conceitos de preparos para lentes e laminados cerâmicos. Cada vez mais, tem sido comum a divulgação da cimentação desses laminados associada à não realização de preparos dentários. Atualmente, esse princípio vem sendo aplicado de maneira generalizada para muitas situações clínicas,...

Introduction: This is the last article of a series of six manuscripts about composite resins in the last 10 years. The composite resin is widely used in clinical dental practice and the knowledge of it behavior in long-term is necessary. Thus, the aim of this literature review is evaluate clinical longevity and failure rate of composite resins restorations. Methods: A broad search was performed in the PubMed/Medline database between 2007 and 2018. After title and abstract evaluation, 65...

Objective: To evaluate the golden proportion of the perceived clinical crown widths of maxillary anterior teeth in orthodontic treated patients and to assess its association with self-perception of dental esthetic concerns. Methods: A group (n=40) of young adults with fi nalized orthodontic treatment had their pairs (without orthodontic treatment) selected according to gender and age using simple sample randomization. Golden proportion of the maxillary anterior teeth was measured with ImageJ...

THE DEFINITION OF CENTRIC RELATION (CR) AND its clinical application still generate much controversy within dentistry. The latest version of the Glossary of Prosthodontic Terms (GPT-9) defines Centric Relation as “a maxillomandibular relationship, independent of tooth contact, in which the condyles articulate in the anterior-superior position against the posterior slopes of the articular eminences; in this position, the mandible is restricted to a purely rotary movement; from this...

I believe we are so immersed in our daily routines that we do not stop to think about the real meaning of our profession

Objective: The aim of this study was to evaluate and compare the dimensional accuracy of models made with type IV dental stone and epoxy resin with different base/catalyst pastes ratios. Methods: A metallic maxillary model with 14 and 16 teeth prepared for full crown without 15 tooth was used for the impression. The impressions were performed with addition silicone (Express XT). The models (n = 10) were made with type IV dental stone (Durone, Dentsply), epoxy resin (Sikadur 32, Sika) with...

FOR US AT WK ODONTOLOGIA, OFFERING PATIENTS a comfortable and welcoming environment has always been the most important. After all, they are fully trusting the health of your smile in our hands. Therefore, some concepts have guided us since the beginning; among them, mainly, the integration with nature, so that we could have a pleasant working environment on a daily basis, thinking both of patients and our team. In this sense, some qualities favor the building where we are based today, such...

AFTER EMPHASIZING THE IMPORTANCE OF THE PHOTOACTIVATION in the modern Dentistry, the next question, that is one of the most frequent when the topic is light curing, is: “Are the light curing units all the same?”. There are light curing units from different brands, with different colors, shapes, performances and prices available for dentists.1 The last is one of the most important factors when choosing a new light curing unit. The equipment’s prices have a great variation in the...

WE LIVE IN A TIME OF INTENSE DISSEMINATION OF KNOWLEDGE. Regardless of profession, area or specialty. We have never had so much access to information.

Introduction: Lithium disilicate-based ceramics have optical properties that make them stand out, and adhesion to the remaining dental structure is obtained from the sensitivity of this group of material to the action of hydrofluoric acid (AF), which allows the exposure of crystals of lithium disilicate and favors bonding to resin cementing agents. For the AF to be used without prejudice to the structural rigidity of the ceramic or to the quality of adhesion, care with its concentration and...

I AM ADDRESSING ABOUT A TOPIC THAT MAY BE LITTLE uncomfortable for some professionals, but it is a constructive criticism for the great area of dentistry. I believe that, many of you see the existing gap, unfortunately, between the knowledge generated daily by researchers and its clinical application in dentistry. At certain times, I have the feeling there is a dispute, no confess, between clinician and researchers to show who is more important for dentistry. Some happenings, which generated...

PEOPLE WITH TEETH PRESERVED IN THEIR function and aesthetics may have tooth loss, which is usually associated with dental trauma. This is because there was a root fracture or traumatic injury induced alveolodental ankylosis followed naturally by tooth resorption by replacement (Fig. 1 and 2).

THAT SELF-ETCH ADHESIVE SYSTEMS ARE ALREADY A REALITY in Restorative Dentistry worldwide, no one doubts. The number of scientific articles available, laboratory, clinical or even systematic reviews, demonstrating the quality and reliability of these systems is very large, and in general, possibly, in great part of Post-graduation Programs in Brazil, these self-etch adhesive systems are the first option when considering restorative procedures. Now, if that happens, why are these adhesive systems...

ATTENTION: THIS PAPER DOES NOT CLAIM TO BE A SCIENTIFIC STUDY; HERE I DESCRIBE CLINICAL EXPERIENCE ASSOCIATED WITH LEARNING ACQUIRED ALONG A 33-YEAR CAREER. Enjoy it!

IN MY PREVIOUS COLUMN, I HAVE DESCRIBED the adhesive cementation protocol that should be used to bond customized Ti-based zirconia implant abutments in implant-supported restorations.

First, I would like to send you our warm embrace in this very difficult moment the whole humanity is going through. A situation never experienced before, when we are all aware of what we are learning to be a better human being as soon as this is all over. I, for example, have learned a lot and keep learning everyday, and I now, more than before, value the simplest and most humane things in our lives and families (and, pardon my language, &#%! the rest). Today we bring you one more column...
