Introduction: According to the Brazilian Society of Plastic Surgery in 2016, 7,362 people underwent bichectomy (BC), which represents 0.5% of the total number of aesthetic surgeries. In an attempt to ...achieve facial harmonization, BC surgery presents little complexity and is based on some well-defined steps. Even when appropriately indicated, it is still a controversial procedure, as there is no surgical technique adequately systematized in current literature, aiming to make it safe and reproducible. Objective: It was to present the main aesthetic considerations and complications of bichectomy, as well as discuss its safe management to avoid and treat problems. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from November 2023 to February 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 96 articles were found, 40 articles were evaluated in full and 28 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 12 studies with a high risk of bias and 10 studies that did not meet GRADE and AMSTAR-2. Most studies did not show homogeneity in their results, with X2=67.9%>50%. It was concluded that on an aesthetic level, performing a bichectomy thins the middle third of the face, outlining and highlighting the bone angulations of the zygomatic region, contributing to a more pleasant facial aesthetics. Surgical removal of the Bichat ball induces a mild inflammatory process controlled by rescue medication, significantly reduces facial volume, and improves the quality of life and satisfaction with facial aesthetics 3 months postoperatively. Several studies have presented the importance of using the Bichat ball as an oral layer to close fistulas and also to cover bone grafts in implant dentistry.
Introduction: Dental caries is highly prevalent worldwide and is responsible for significant morbidity. Metabolic diseases such as diabetes and obesity share several common environmental determinants ...with tooth decay. Cardiovascular disease is a common and complex disease, with high morbidity and mortality rates, representing a serious threat to human health. Objective: It was to develop a systematic review to present, through clinical studies and systematic reviews/meta-analyses, evidence of the relationship between periodontal diseases/cavities and cardiovascular diseases. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from November 2023 to January 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 108 articles were found, 36 articles were evaluated in full and 17 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 24 studies with a high risk of bias and 22 studies that did not meet GRADE and AMSTAR2. Most studies did not show homogeneity in their results, with X2=64.7%<50%. It was concluded that dental diseases such as periodontitis and tooth decay increase the risk of cardiovascular diseases. The number of missing teeth is significantly associated with selfreported history of stroke. The bacterium Streptococcus mutans, harboring the Cnm gene encoding the Cnm collagen-binding protein, is associated with the development of hypertensive intracerebral hemorrhage.
Introduction: Orthognathic surgery is indicated to modify the position of the maxillomandibular structure, which may cause changes in the sagittal position of the mandibular condyle in individuals ...with retrognathism and mandibular prognathism. In the context of orthognathic surgery, anterior open bite (AOB) is an easily recognized malocclusion and presents only aesthetic and functional problems. Objective: Foi desenvolver uma revisão sistemática para apresentar as principais considerações da cirurgia ortognática em pacientes classe II. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from October to December 2023 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 88 articles were found, 40 articles were evaluated in full and 20 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 21 studies with a high risk of bias and 21 studies that did not meet GRADE and AMSTAR-2. Most studies did not show homogeneity in their results, with X2=57.5%>50%. The etiology of anterior open bite is multifactorial and may be caused by environmental and hereditary factors. Class II patients may have significantly greater amounts of lateral and inferior translation than class III patients. Two-jaw surgery for open bite correction led to different directions and amounts of condylar rotational displacement in patients with skeletal class II malocclusion. Treatment can be carried out through preventive, interceptive, corrective, or even surgical treatments. The differentiated bonding of brackets to the anterior teeth is also a very useful resource for the treatment of anterior open bite.
Oral cancer is a multifactorial disease resulting from changes in the DNA of cells present in the oral cavity, altering their natural structure and consequently causing a mutation in the ...Deoxyribonucleic Acid chain. Several extrinsic factors can cause oxidation of the DNA chain, such as smoking, alcoholism, human papillomavirus (HPV) virus infection, and a diet poor in antioxidants present in fruits and vegetables in general. The association of more than one factor can further increase the chances of developing this pathology. The objective of this study was to search the literature for articles that report an association between harmful habits, such as smoking, alcohol consumption, and HPV virus infection, with the risk of developing oral cancer. The articles used were extracted from online databases, such as PubMed, Scielo, and Google Scholar to gather research on the topic in question.

Introduction: The deleterious habits in children, in the deciduous dentition phase, seem to be present in more than half of the child population, reaching rates greater than 90%, depending on the ...population studied, and dentofacial alterations may already be present in half of these individuals. Early identification is essential so that malocclusions, which are more difficult to treat, do not set in. Objective: It was to carry out a brief systematic review to highlight deleterious oral habits, as well as to point out their main predictors and treatments. Methods: The systematic review rules of the PRISMA Platform were followed. The research was carried out from April to June 2023 in Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 87 articles were found. A total of 32 articles were evaluated in full and 16 were included and developed in this systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 6 studies with a high risk of bias and 43 studies that did not meet GRADE. Since pediatric follow-up is more frequent than consultations with the pediatric dentist, the early identification of deleterious habits by physicians is of fundamental importance in referring these patients to dental treatment that diagnoses and removes these habits, before difficult-to-resolve malocclusions get settled. Preventive measures should also be taken, guiding parents so that deleterious oral habits do not take hold, such as a minimum period of six months of breastfeeding, finger sucking should be replaced by an orthodontic pacifier, the bottle should have an orthodontic spout, removing the habit of pacifier and bottle until the age of three. There is an association between deleterious habits and different types of malocclusions in different planes of space, with atypical swallowing being a habit that must be diagnosed early.
Introduction: Over the past three decades, the number of dental implant procedures has been around one million dental implants per year. The development of biomaterials for use in clinical dentistry ...is a powerful therapeutic instrument in the correction of bone defects. Objective: It was to carry out a concise systematic review of bone regeneration processes using biomaterials and the main molecular and cellular constituents for implant dentistry. Methods: The survey was carried out from May to July 2023 in the Scopus, PubMed, Science Direct, and Scielo databases, using older scientific articles with a gold standard reference up to 2023. The quality of the studies was based on the GRADE instrument and the risk of bias by the Cochrane instrument. Results and Conclusion: It was found 162 studies that underwent eligibility analysis. The final sample had 31 eligible studies that were described in the systematic review. Most studies showed homogeneity in their results, with I2 =24.9% <25%. Due to bone regeneration and biological barriers in graft surgeries, there has been a technological growth of these materials as they point to potential tools for treating bone loss. The greater potential of guided bone regeneration was associated with the graft material due to the higher grade of vital bone and the lower percentage of residual graft particles. All studied bone substitute materials resulted in efficient bone formation for dental implants and alveolar ridge preservation procedures. It was concluded that bioengineering and cell therapy work together for regenerative dentistry, favoring and improving biological conditions to accelerate tissue repair and regeneration and, thus, naturally maintaining tissue homeostasis. This condition is maintained because the required cellular elements are provided, the cell proliferation and differentiation factors, and supramolecular structures that guarantee the functional stereochemical organization of the generated tissues and their systemic integration.
Abstract
Police are required to operate in complex social, political, and organizational environments. Nowadays, challenging times highlight the role that police leaders play in ensuring that the ...organization is effective in dealing with such environments. The purpose of this paper is to expand the systematic review of literature of Pearson-Goff and Herrington (2014, ‘Police Leadership: A Systematic Review of the Literature.’ Policing: A Journal of Policy and Practice 8(1): 14–26) by: (1) including studies after the date considered by the authors; (2) following the PRISMA-P approach to systematic reviews; and (3) include European studies. Based on 7,041 records, which ended up in 101 eligible empirical pieces, evidence supports previous findings about what are the characteristics of police leaders as well as the actions expected by them. This comprehensive systematic review also identifies additional characteristics and actions that are important nowadays in police leadership. Overall, the current study encourages future studies on the thematic, and contributes to practitioners aiming to develop continuous improvement strategies inside the police.
Introduction: The rehabilitation of the dental arch with osseointegrated implants makes it possible to improve the quality of life of patients. Guided bone regeneration (GBR) has been applied to ...replace lost bone to allow the implant to be fully integrated and maintained during functional loading. GBR is considered one of the most commonly applied methods to reconstruct alveolar bone and to treat peri-implant bone deficiencies. Objective: It was to develop a systematic review to highlight the main approaches of guided surgery to promote bone regeneration in implant dentistry. Methods: The systematic review rules of the PRISMA Platform were followed. The search was carried out from March to May 2023 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases, using articles from 1977 (Golden pattern - Bra°nemark et al. ) to 2023. Results and Conclusion: A total of 117 articles were found, 38 articles were evaluated and 28 were included and developed in this systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 22 studies with a high risk of bias and 15 studies that did not meet GRADE. It was concluded that the application of a membrane to prevent nonosteogenic tissues from interfering with bone regeneration is a fundamental principle. Membrane properties and biological outcomes drive bone regeneration in membrane-covered defects. Barrier membranes play the role of preventing the invasion of soft tissue by exiting the mucosa and creating an underlying space to support bone growth. Collagen membranes have excellent biological properties and bone regeneration results. While collagen membranes do not provide sufficient mechanical protection of the covered bone defect, titanium-reinforced membranes, and non-resorbable membranes need to be removed in a second surgery.
Introduction: The temporomandibular joint (TMJ) is composed of dense fibrocartilage formed between the mandibular condyle and the temporal bone. The high collagen content of this disc provides great ...rigidity and durability. Osteoarthritis-like degenerative joint disease belonging to temporomandibular disorder (TMD) is a destruction of bone and cartilage with a consequent inflammation that enhances tissue destruction. As a treatment, the implantation of a total alloplastic TMJ prosthesis is an innovative approach to the treatment of TMD. There are two types of prefabricated (stock) and custom computer-aided design/computer-aided manufacturing (CAD/CAM) systems. Objective: The present study aimed to carry out a concise systematic review of the major clinical approaches of prefabricated and customized prostheses for the temporomandibular joint. Methods: The systematic review rules of the PRISMA Platform were followed. The search was carried out from February to May 2023 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases, using articles from 2018 to 2023. Results and Conclusion: A total of 107 articles were found, 34 articles were evaluated and 19 were included and developed in this systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 21 studies with a high risk of bias and 15 studies that did not meet GRADE. It was concluded that the clinical results of the stock and CAD/CAM prostheses suggested major improvements in mouth opening and reduced pain as a result of the rehabilitation of temporomandibular joint function. The results showed comparable data for the two types of prosthesis design at 6 months postoperatively. Thus, both temporomandibular joint and custom implants work well despite the additional advantages of custom prostheses, along with increasing access to digital technology, which may result in custom devices dominating the market in total temporomandibular joint replacement systems.
Since the Industrial Revolution, large amounts of greenhouse gases (GHGs) have been released to the atmosphere which led to global warming and climate change. Despite the efforts from nations to ...limit the temperature rise to 1.5 °C, as defined in the Paris Agreement (2015), if emissions do not half until 2030, it is likely to achieve a global warming of 2.7 °C by the end of the century.Thus, the assessment of environmental performance become crucial. The objective of this thesis is, then, to measure and compare the environmental efficiency at the country level, over the period 2000-2018, being its main contribution to overcome the lack of literature studies with a global scope.To answer the research questions (How can countries be ranked in terms of their performance? What have been the best and worst performing over time?), a DEA methodology (additive model) was employed. DEA has become a wellestablished tool to judge the relative efficiency in the environmental field. A clustering analysis was also carried out to distinguish countries based on their proximity-to-target value (%), in 2018. The DEA model includes three inputs (population, energy use and GHGs emissions) and two outputs (GDP and renewables). The population and GDP are non-discretionary variables.Regarding the main findings, globally, countries have become more efficient over time. Bhutan, Kiribati, Norway, Nepal and Iceland have been the efficient countries that appear more times in the reference set of other countries, being an example of best practices. In 2018, the poorest 5 performing countries were Russia, followed by Iran, Saudi Korea, Saudi Arabia, and South Africa, being all inefficient since 2000. Despite being inefficient during most of the years, China, United States and India significantly improved their performance which was mainly explained by their higher consumption of renewables.
