Background: Numerous studies evaluating the clinical and histologic effects of enamel matrix derivative (EMD) as an adjunct to periodontal surgical therapy have demonstrated significant improvements in clinical parameters, radiographic bone fill and periodontal regeneration. Case presentation: Two case reports are described that involved treatment of intrabony defects with periodontal flap surgery and placement of enamel matrix derivative. Each case was followed up after 12 months for clinical and radiographic evaluation. Both cases resulted in a reduction in probing depth (PD), a gain in clinical attachment level (CAL), an absence of bleeding on probing (BOP), unremarkable changes in gingival recession (REC) and radiographic evidence of bone fill. Conclusion: Treatment of an intrabony defect with periodontal flap surgery and EMD demonstrated bone fill as evidenced by radiographic evaluation performed after 12 months. Consistent improvements in the clinical parameters of CAL, PD and BOP were also noted.

Trauma is defined as damage with or without intention caused to the organism by a sudden exposure to energy sources that exceed its tolerance margin. In turn, facial skull trauma is described as one that affects the dentoalveolar complex, bony structures and soft tissues of the maxillofacial territory.1 The Nasal-Orbit-Ethmoidal Complex fractures cover the middle area of the midfacial third, being extended fractures when they have a bilateral commitment, with a high aesthetic compromise and difficult to handle, thus becoming a great challenge for maxillofacial surgeons.1 The Nasal-Orbit-Ethmoidal complex corresponds to a complex structure formed by the nasal bones, nasal septum, nasal-frontal process, ethmoids, papiraceous laminae of the lacrimal bone and sphenoid, so any alteration of these structures will have important functional and aesthetic consequences.3 Nowadays, there are several ways to approach these fractures, the coronal approach being the most used since it allows a correct access and visibility of the nasal frontal area. Despite this, this approach requires precision and surgical expertise. On the other hand, due to the area of the incision, hair less patients have a considerable aesthetic impact.4 Below are two cases of Nasal-Orbit-Ethmoidal fractures evaluated and treated by the maxillofacial surgery team at the El Carmen Metropolitan Hospital, Santiago, Chile. Both required neurological and ophthalmological evaluation, discarding commitment at that level. The first case corresponds to a patient with an extended fracture of the Nasal-Orbit-Ethmoidal complex in which an approach was made through pre-existing lacerations in the frontal nasal area, complementing it with a transconjunctival approach with extension and lateral canthotomy to access the lateral wall and floor of the right orbit. The second patient corresponds to a patient with a fracture of the frontal component and Nasal-Orbit-Ethmoidal which was approached by means of a coronal incision. Cases

Hospital infections represent a global public health problem and are a risk to users of hospital services. Postoperative infections, currently referred to as surgical site infections (SSI), account for a significant proportion of all of these hospital infections.1 Among the practices for the prevention of SSI, degermation of the hands and forearms of the surgical team, as a preoperative preparation, had its origin when Ignaz Semmelweis, in 1847, advocated the use of germicide for washing hands before examining the parturient.2,3 The effect of skin antisepsis on reducing surgical site infection has been historically demonstrated by Joseph Lister (1827-1912). At that time, surgical gloves were not yet available, which made proper antisepsis of the patient’s skin and of the hands of the surgeon even more important.4 The hands act as a reservoir of microorganisms, considered the main route of transmission of pathologies, presenting the highest index of hospital infection. Even with the use of gloves, micro perforations may occur due to their use, in addition to contamination of the hands during their withdrawal.5 Human skin is colonized by bacteria, whose density varies according to the sites. The species found in the hands are classified into two groups: resident microbiome and transient microbiome.6 The bacteria of the transient microbiome, despite having greater pathogenicity, appear to be removed by hand hygiene, as they are more superficially and poorly adhered to the skin.7 The hand hygiene activity has been associated with a significant reduction of hospital infections. Evidence from experimental and non-experimental studies is fairly consistent with the hypothesis that handwashing is a causal association with reduced risk of infection.6−9 Care with the surgical degermation of the hands and forearms is justified by the perforation rate of the gloves at the end of the surgery of 18%, and in more than 35% of the cases these perforations are not perceived by the surgeons, besides the fact that some gloves are permeable to bactéria.10 The purpose of pre-surgical antisepsis is to reduce the resident and transient microbial load of the hands, thus reducing the introduction of microorganisms into the surgical site1. It is fundamental for the practice of hygiene, especially when referring to a health professional, who, in order to perform any type of surgical procedure, should use antiseptic solutions because they promote a greater reduction of microorganisms.6 Not necessarily this technique requires soap and water to be effective. Clinical trials have demonstrated the effectiveness of techniques without rinsing, in which alcohol-based solutions are used for pre-surgical hygiene.6,9,11,12 To help countries and health facilities adopt alcohol-based products as a gold standard for hand hygiene, the World Health Organization (WHO) has developed formulations for local preparation as an alternative when appropriate commercial products are not available or

Esthetic prosthetic restorations, with natural reflection, color from within and color gradients influenced by the internal dentinal core anatomy can best be accomplished by veneered zirconia, rather than with crowns of color and structure graded monolithic zirconia. Concern about the high incidence of chipping with some of the porcelains for zirconia substructures has led to a massive shift from veneered zirconia to the use of monolithic zirconia for crowns and bridges. Because zirconia has four times the hardness of metal, initial concern about antagonist abrasion could with numerous studies be negated. Clinical long-term effects of lack of abrasion of full zirconia crowns, in comparison with 30-75 μm/year for surrounding and opposing dentition is still poorly documented. Massive crack formation in enamel probes has been reported in specimens after in-vitro fatigue testing with opposing monolithic zirconia. In-vitro and clinical studies have shown that only reinforcement of the structure of veneering material can prevent chipping. This article compares the fatigue behavior of three-unit bridges with a substructure of Primero zirconia veneered with Primero Enamel (PR) with bridges with Cercon Base zirconia inner-structure veneered with Ceramco PFZ and Cercon Ceram S (CR1 and CR2) and assess the possibilities and increase their scope to cognitive design and manufacturing of porcelain veneered zirconia crowns and bridges. Fatigue testing of four times eight 3-unit bridges were produced for each of the three porcelains and a reference. The results show that efficient crack-stopping prevented chipping with the PR bridges, while the bridges with conventional porcelains CR1 and CR2, showed failures. We conclude that chipping is mainly porcelain related. Cognitive design and fabrication of the dentin zirconia core will lead to prosthetic mimetic restorations (PRIMERO) with natural esthetics.
美观的修复体，具有自然反射、内部颜色和受内牙本质解剖结构影响的颜色梯度，最好由贴面氧化锆完成，而不是使用颜色和结构分级的整体氧化锆冠。由于担心氧化锆下部结构的陶瓷容易碎裂，人们开始大规模地从贴面氧化锆转向使用整体氧化锆来制作冠和桥。由于氧化锆的硬度是金属硬度的四倍，因此可以通过大量的研究来消除最初对拮抗磨损的担忧。与30-75 μm/年的周围牙列和对牙列相比，全氧化锆冠无磨损的临床长期影响仍然缺乏文献记载。搪瓷探针在用对立的单片氧化锆进行体外疲劳试验后，有大量裂纹形成的报道。体外和临床研究表明，只有加强贴面材料的结构才能防止碎裂。本文比较了底质氧化锆贴面Primero搪瓷(PR)和内质氧化锆贴面Ceramco PFZ和CerconCeram S (CR1和CR2)的三单元瓷冠桥的疲劳性能，评估了瓷贴面氧化锆冠桥的认知设计和制造的可能性，并扩大了它们的应用范围。对这三种瓷器分别进行了4次8次3单元桥的疲劳试验，并进行了参考。结果表明，PR瓷桥具有有效的止裂效果，而CR1和CR2瓷桥存在断裂现象。我们得出结论，碎裂主要与瓷器有关。牙本质氧化锆核的认知设计和制造将导致具有自然美学的假体修复(PRIMERO)。

The convergence of orthodontic and periodontal considerations in diagnosis and treatment planning should become common place in clinical practice. While there has been a large number of systemic conditions1 and specific periodontal pathogens linked to periodontitis, the bacterial flora of malpositioned teeth present a unique challenge both in the pathophysiology of periodontal disease and possible systemic consequences. The pathophysiology of periodontal disease is modulated by the host immune response and tissue structural considerations, but the key components in disease are associated with the bacterial flora in plaque biofilm.1 Periodontal pathogens produce localized damage in two different ways:

Ergonomics is the science that studies the relation of the human being to the work, trying to develop a perfect integration between the conditions of the environment, the capacities and physical and psychological limitations of the worker and the efficiency of the productive system. Its purpose is to increase human efficiency through logical decisions. In this sense, ergonomics acts in the removal of negative aspects of the work that in the long run can cause inefficiencies or the most varied types of physical incapacities.1 The difficulty in establishing a balance in the work-machine-environment trinomial has pointed to dentists as individuals vulnerable to occupational hazards. The Ergonomics applied to Dentistry has a fundamental role for the success of the actions developed during the dental care. Its objectives are: to rationalize work; eliminate non-productive steps; produce more and better; provide greater comfort and safety to the patient; obtain means and systems to reduce physical and cognitive stress; and prevent diseases related to dental practice, thus seeking a more expressive productivity.2 In this context, the ergonomic parameters related to the environment appear as decisive in maintaining the balance in dental work. In dentistry, lighting should be as appropriate as possible to ensure safety and health for the dental surgeon, since this professional belongs to a class that is at risk of eye trauma. This is due to the fact that, during his work, to fix the look in small details for a prolonged time, analogous problem of the typists. Consequently, you may blink less and get your eyes dry and burning, an injury called ciliary musculature spasm.3 Dental work requires motor coordination, reasoning, discernment, patience, safety, skill, delicacy, firmness and objectivity. Activities that together require a lot of the professional. In this way, adequate environmental parameters can make a difference in the performance of the work activities in a comfortable way and with the minimum of damages to the worker’s body.1 In the scientific literature on the ergonomic parameters of the environment, studies that analyze the dental clinic are few. Thus, there is a need to carry out a study to evaluate this data in the workplace of the dentist, in order to identify and solve possible flaws. The present study evaluated the ergonomic parameters of illuminance of the school dental clinics of a Brazilian University.

The influence of aesthetics on the various dentistry specialties is increasingly more relevant. Areas that historically have focused on treatments to restore oral health are currently driven to seek solutions to aesthetic interventions. Also, different specialties have sought to interact with the aim of achieving better aesthetic outcomes. Currently, the relationship between prosthesis and periodontics overcomes the need of rehabilitation and maintenance of periodontal health. The restoration procedures are significantly hindered in situations such as loss of soft and bone tissue that cause the appearance of defects, mainly in the anterior region, when surgical interventions are not possible. In these cases, dentogingival prosthetic restoration is a viable alternative for the aesthetic and functional restoring.1,2 Current ceramics used in dentogingival prostheses are known to be aesthetically fit since they simulate the natural color of teeth and have adequate physical properties. However, the ceramics that simulate gingival color offer a less than optimal result. The alternative choice, with a better pink aesthetic, is the gingival color compound resin. This material, however, raises questions regarding bond strength with porcelain infrastructures.3−5 The concept of adhesion has changed the dental practice, placing adhesive dentistry in constant evolution. New and improved products are constantly being introduced to the market, motivating research to unveil and compare behaviors under different conditions. However, mechanical, chemical and mechanicalchemical methods are still designed to promote an adequate irregular surface and optimize mechanical retention of the resin. The ceramic surface can be treated with acids,6,7 or with diamond-tipped burs and blasting.8,9 Given this context, the aim of this study is to analyze the bond strength between feldspar ceramic Creation (Willi Geller International GmbH, Meiningen Austria) and the gingival compound resin Amaris Gingiva (Voco, GmbH, Cuxhaven, Germany) using shear strength testing and thermal cycling. The analysis will consider two adhesive bond agents: 3M ESPE Adper Single Bond Plus and 3M ESPE Adper Scotchbond Multi-Purpose Plus with or without surface treatment (blasting with aluminum oxide of 50μm).

The best bonding to enamel is achieved by selective etching of enamel margins [SE] (with phosphoric acid gel) prior the application of self-etch one-step multi-mode universal adhesive [SEUA].1‒11 When using the self-etch approach, the adhesion depends on the material formulation. Particularly for mild SEUA (e.g. Scotchbond Universal Adhesive (SBU)), systematic reviews showed a less favorable adhesion to enamel.12,13 In this line, despite the relevance to predict clinical outcomes,14‒16 few in vitro studies about SBU have addressed microtensile bond strength [μTBS] to enamel under the influence of SE.2,5, 6 Besides, the effect of storage water thermocycling time should be also highlighted. Reduced μTBS values were observed when human enamel blocks underwent storage for 24-hour,2 maybe a short time for accurate measures failures. Longer time (12-month) studies (which should be encouraged in order to predict the clinical effectiveness of adhesives),17 do not definitively aver that question.6,11

In spite of the measures taken, with the disruption of enamel and dentin it is necessary to use a restorative material to attend the progression of the caries disease. The decision of the material varies according to the type of lesion, cavity size, working protocol, among others. However, the difference is the use of fluoride varnish during treatment, which due to its properties it would be understood that it could lengthen the lifetime of the restoration, as well as maintaining its remineralizing effect on the remaining structure.5,6
