I often call people (teachers) who alarm others about everything as “chaos advertisers”. You know them because they are always saying, “The end is near”! “Chaos is imminent”! “Dentistry has already changed, and if you don’t follow it, you’re out”! Something in that line.

ULRICH LOHBAUER is the supervisor of the Dental Biomaterials Research Laboratory of Dental Clinic 1 (Operative Dentistry and Periodontics). The interests of the Laboratory are focused on the mechanical performance of dental materials such as multilayer ceramics, Nano particulate polymers or biocompatible and self-adhesive cements. The adhesive interface studied at the nanometer level for human tissue plays a central role in the microstructural evaluation of the tooth-restoration joint. An...

ABSTRACT: Introduction: Fractures in anterior teeth are frequently considered as emergencies in dental practice. Crown fractures not considered complicated involve enamel and dentin and may receive different levels of treatment, such as bonding the dental element or restoring it with composite materials. Objective: The goal of this study was to perform aesthetic and functional rehabilitation through the use of composite resins. Three cases of patients who suffered different degrees of...

ABSTRACT: Introduction: This is the fourth article of a series of six manuscripts about composite resins in the last 10 years. The polymerization shrinkage is part of photopolymerization process and may cause shrinkage stress. It may be related to microleakage, enamel cracks, postoperative sensitivity and secondary caries. The aim of this literature review is to synthesize shrinkage polymerization data of different composite resins and discuss the postoperative sensitivity results of several...

In order to approach and discuss the results of relevant topics in aesthetic dentistry, this section high- Lights will present a topic very popular among dental professionals: the use of light sources in dental bleaching. For this purpose, recent articles published in the important international journals were selected, which address different light emitters used during in-office bleaching.

ABSTRACT: Objective: The aim of the present study was to evaluate the effect of different surface treatments and the processing of a lithium disilicate ceramic on bond strength and interfacial characteristics with a photoactivated resin cement. Methods: 20 pressed blocks (IPS e.max Press) and 20 blocks using the CAD / CAM technique (IPS e.max CAD) (10-mm diameter x 1-mm thickness) were made. Each type of processing was divided into four groups (n = 5), according to the type of surface...

ABSTRACT: Introduction: The satisfactory performance of a restorative material when exposed to chemical challenge may be relevant for its clinical indication. Objective: This in vitro study investigated the effects of chemical challenge on compressive strength (CS), diametral tensile strength (DTS), surface roughness (R), surface hardness (H), fluoride release (F) and morphological characteristics (SEM) of popular restorative glass-ionomer cements (GICs). Methods: Maxxion R (MX) and Magic Glass...

What would be the rationale for a dental occlusion section in a renowned Esthetic Dentistry journal? With esthetic treatments becoming more popular each year, unexplained failures are happening and require a better understanding of the masticatory system function. Moreover: the expectation relies in the belief that understanding occlusion, all the failures could be avoided. However, assigning to occlusion all responsibility for the success or failure of our treatments may not be reasonable.

Dentistry can’t be everything. No job could. I decided to leave my professional box and go beyond words to talk about life. I wasn’t born a dentist; I became one. Dentistry can’t be the north for a life well lived. Unless you work with smiles, not teeth. I see a lot of people talking about laminates and ceramic protocols, resins vs. ceramics, pure dentistry, but the act of smiling goes beyond and transcends technique. To make yourself smile, it’s not enough to be a dentist; you have...

ABSTRACT: Objectives: To determine: (a) the influence of the light-curing unit (LCU) type (“monowave” vs. “polywave”) on the degree of conversion (GC) as a function of depth, for different formulations of bulk-fill composites; (b) which light evaluation parameter is able to predict photoactivation as a function of depth of bulk-fill composites; and (c) verify whether these parameters are related to the cost of the light source. Methods: Four LED-based sources were used (Poly...

Autrán Dental is a newly created space, located in the neuralgic center of people’s routine, on the avenue with the greatest architectural identity of the city and in front of the Pedrera building, object of worship by all lovers of Gaudian architecture and, by extension, of most of the visitors of the city.

light curing adhesives, resin-based composites, sealants and resin modified glass ionomers, also in procedures that involve indirect restorations, such as cementation of restorations and intraradicular retainers with resin-based cements and even the bonding of orthodontic brackets. To summarize, the Esthetic Dentistry is highly dependent of the light curing. This, associated with the knowledge that color stability1, biocompatibility2 e mechanical resistance3 are directly related with the...

Note: This text is not a scientific paper. Here, I describe the clinical experience brought by learning during a 32-year-long career. I hope you enjoy it! In this paper, I describe why I use Prep Start, a pressure-controlled aluminum oxide abrasion unit. The use of this unit has been part of our clinical protocols for over 15 years. As soon as it was introduced in Brazil, the use of aluminum oxide abrasion to prepare cavities, instead of burs, raised great interest from dentists, who wanted...

Digital Dentistry has advanced rapidly, increasing the use of customized hybrid abutments and restorations designed to be fixed to a titanium base, also known as Ti base. Titanium abutments, whose long-term longevity has been assigned to their physical properties, provide sufficient mechanical resistance to be used as a base for final restorations. Zirconia abutments may be customized to obtain a more superficial cementation line in relation to the gingival margin, slightly going into the...

The evolution in the last decades in any professional activity, mainly in the functions of information technology and explosion of interaction through social networks, has caused changes. However, these changes do not always result in benefits. In this perspective, Dentistry as such an elementary area of health has often been neglected by some worrisome practices. When I say “worrisome practices”, I am not referring to the first moment in clinical practice, but far beyond that, I am...

In June, the 23rd Meeting of the Group of Brazilian Teachers of Restorative Dentistry (GBPD) was held in the Hotel Prodigy Santos Dumont, in Rio de Janeiro. Our objective was to hold a conference that gave priority to both clinical practice and research, particularly to the teaching of Restorative Dentistry. That was not an easy task; we had to hold numerous meetings and discussions to clarify several questions. There was a great amount of anxiety and several concerns about having an event...

ABSTRACT: What are the criteria to leave an unerupted tooth in the maxillary bones? To control this situation, it is required a prior knowledge of the pericoronal follicle, especially its structure, its functions and the impact of its permanence. Through medical imaging, there are criteria to assert that it is normal and it involves evaluating the image, thickness, outline and the limits of the pericoronal follicle. Some diseases are exclusives from pericoronal follicle and therefore they...

The bare truth about Instagram Here we are for one more issue. I should confess that I am, and we all are, very happy about this Journal’s repercussion, with its honest and reliable contents, whose clear and objective aim is to be shared with you and to support your clinical applications. In this issue, you will find some more cases - this time we imagine that Instagram feeds, which do not openly display the number of “likes” that a post has received, may have made many people unhappy...
