We come from (when I say “we”, I mean “I”, but we sound more polite…) a city where I believe a big movement started: Curitiba. I’d like to be more precise – and you may correct me – but around the late 1980’s and beginning of the 1990’s, there was an Esthetic Dentistry group focused on composite resins, maybe the first in Brazil, named Neo Nous. The late Prof. Edino Beltrami, Prof. Renato Leite Rosa, Prof. Newton Fahl, Prof. Paulo Gonçalves dos Santos… I believe there...

Dr. Sadr is a Clinical Associate Professor at Department of Restorative Dentistry, Director of Operative Dentistry Pre-clinical Training and Associate Director of Biomimetics Biomaterials Biophotonics & Technology (B4T) lab- oratory at University of Washington School of Dentistry.

In this issue of the highLIGHTS section we will address another topic of interest to dentists, Absolute Isolation. Although it has been a topic discussed for many years and with a lot of evidence available, currently some aspects are worth being approached with greater criteria and assiduously updated to the clinician in general.

Introduction: The use of the Digital Smile Design (DSD), is a growing trend in dentistry. It is an effective tool in communicating with the patient about the esthetic possibilities before starting the treatment, and allows the predictability of results and communication with other members of the dental surgeon team, including the technician from the prosthesis laboratory. Objective: This clinical case aims to present the use of digital smile design in the correction of the anterior occlusal...

It is known that dentists in general have never been totally united. There is some competition between areas, departments, universities and professionals who work in the same neighborhood. Nevertheless, the Brazilian Dentistry is experiencing an exponential growth in the number of undergraduate courses and accredited professionals. Thus, the competition for the patient or student in a postgraduate course is increasingly fierce. In this sense, many professionals with no teacher training try to...

“Mucous cysts of the maxillary sinus” frequently are a clinically important occurrence, as they can induce apprehension in patients and concern in professionals, who are responsible for providing patients with explanations and raising their awareness of the presence of these entities, when necessary, treating them. Among the different types of these lesions, the mucosal retention cyst - with or without extravasation (burst or ruptured), maxillary sinus polyp and its pseudocyst variant,...

Introduction: Dental ceramics are widely used for restorations of anterior and posterior teeth. Restorations longevity is directly related to piece resistance. Hydrofluoric acid (AF) is one of the most used agents in the interaction of cement with the piece. Objective: surface roughness promoted by 10% hydrofluoric acid for 20 seconds, expired date 8 days ago, was evaluated. Methods: 16 specimens of ceramic reinforced by lithium disilicate were made, divided into 2 groups, according to the...

Introduction: External Cervical Resorption (ECR) presents complex and invasive pattern, and its etiology remains little known. Besides, it has aggressive nature, which results in significant dental structure loss. Observations have shown that some predisposing factors trigger the resorption process, among them one finds dental trauma, internal bleaching and orthodontic treatment. Aim: Reporting the multidisciplinary treatment based on an ECR clinical case. Case report: A 26-year-old female...

Introduction: This study aimed to evaluate the influence of different layer thicknesses, orientation angles, and post-polymerization on the degree of conversion of a 3D printing resin to dental casts. Methods: 3D printing was performed with a 405 nm digital light processing printer (DLP) commercially available resin for dental casts in gray color. The thickness of the layers, the orientation of the piece, and the influence of the post-cure were evaluated. The samples were evaluated for their...

In a universe of similar environments and standardization of results, the elaboration of ideas and exclusive projects becomes a creative challenge, which demands intellectual effort, interpretation of practically intangible desires and a conceptual design that seduces. In this duel between the subjective and the objective, architect Maisa Saud and Interior Design Ana Paula Meirelles created the Estúdio Versi - Estética e Função, by the partners Paula Cardoso, Lúcio Monteiro and Rafael...

To answer the required photoactivation time for each resin-based material, we must understand the concept of radiant exposure, which is the irradiance applied for a given exposure time. The term irradiance means the flow of energy or radiant power (mW) received per unit of area. In Dentistry, the area is expressed in cm2, therefore the irradiance is expressed in mW/cm2. Thus, it is important to know the irradiance to define the clinical exposure time.

Introduction: Selecting materials and techniques for the esthetic and functional rehabilitation of patients with severe tooth wear caused by parafunctional habits is challenging. Composite resins occlusal increments could rehab the patient’s loss of vertical dimension, providing comfort during function, while ceramic veneers could be used in anterior teeth because of the optimal esthetic and chemical stability. Thermally modified composite resins may be used to cement ceramic veneers...
