Night work represents a double alteration as it is working at night and sleeping during the day. Health professionals are one of the groups affected by night shift work, an aspect that may have an impact on the quality of care. The objective of this paper seeks to evaluate sleep disorders associated with night work in 20 health professionals from the Praxxel clinic in the period 2021-2022. For which analytical research is used, with a known universe that corresponded to the sample and was made up of 20 health personnel workers from the Praxxel Clinic in the city of Cuenca. To whom the Epworth scale was applied, and a questionnaire to collect additional information, the results show that 75% of the staff have light sleep disorders and only 20% of the health professionals of the Praxxel Clinic in the city of Cuenca interviewed, showed moderate or severe sleep impairment, in conclusion the working conditions were good according to the majority of the interviewees, although the difficulties in the working conditions of some participants cause them to present sleep disorders.

Introduction. The growth of the jaws is influenced by mouth breathing or other habits during infancy. Rapid maxillary expansion is an orthodontic procedure that seeks to correct malocclusion problems and improve the growth and size of the airways. Objective. From an academic point of view, this systematic review aims to examine the effects of rapid maxillary expansion on the airway in children 7-10 years of age. Methodology. The literature was searched in digital databases such as PubMed, Epistemonikos, Dialnet, Ovid, ProQuest, Lilacs, Web of Science, Springer. The search was restricted to articles in English, Spanish and Portuguese published from 2018 to 2022. Results. After applying the inclusion criteria, a total of 965 articles were obtained and reviewed. The literature review was performed on 19 articles that met the inclusion criteria and had adequate evidence to be incorporated in the review. Conclusion. The available literature revealed that rapid expansion of the maxilla at ages 7-10 improves the passage of air into the nasal cavity by increasing the length of the upper airway.

Introduction. The oral mucosa is an easily accessible site for the development of various pathologies, whether of localized or generalized origin, since most oral mucosal diseases have implications for opportunistic microorganisms of ambulatory or hospitalized character; thus, these oral pathologies presented in adults wearing orthodontic appliances could create favorable conditions for the increase of bacterial plaque, including periodontal pathogens with systemic repercussions. Objective. To determine the frequent oral pathologies that occur in adults with fixed orthodontic appliances. Methodology. The literature was selected through a search in the electronic scientific databases: Pubmed, Scopus, Google Academic, Dialnet, Proquest, Pesquisa, Epistemonikos, Taylor & Francis, with no language limit and a time frame from June 2013 to June 2023. Results. A total of N = 1523 was obtained, of which the present literature review analyzed 17 articles that met the inclusion criteria and had adequate evidence to be included in the review. Conclusion. The available literature revealed that adult individuals with fixed orthodontic appliances may present various oral pathologies during their treatment, and among the most frequent pathologies due to poor oral hygiene are gingivitis, periodontitis, caries, decalcification of the dental enamel, and the formation of white spots, among others. On the other hand, to minimize these risks, it is essential to maintain a rigorous oral hygiene routine, including regular brushing, flossing, and mouthwashes recommended by the orthodontist. In addition, it is crucial to attend regular dental checkups to detect and treat any oral problems early.

Introduction: The concept of aesthetic appliances in orthodontics has undergone constant renewal; invisible treatments are increasingly attractive to patients. This trend has been overshadowed by the difficulty of using the technique and the laborious learning curve. The following review aims to provide the reader with all the current information on lingual orthodontics by compiling literature from its success to decline and resurgence, as well as its impact towards the future with the aim that the references presented here allow the lingual system to be the orthodontist distinctives mark in modern orthodontics. Methodology: The systematic review in charge of collecting information on Lingual Orthodontics was conducted through an extensive electronic search in various digital databases such as PubMed, Web of Science, ProQuest, Cochrane, Epistemonikos, Springer, Ovid, Google Academic, Scopus, Taylor, and Francisco. The search for information was conducted from 1982 to 2022 in Spanish, English, French and Portuguese. Results: For this review, a database registry was established with a total of N= 3,684 studies. A first screening was conducted, leaving 2,549 articles; After this selection, the duplicate bibliography was eliminated, leaving 2,062 articles. After checking all records, 2,036 studies that did not meet the selection criteria were excluded, resulting in 26 articles suitable for this systematic review. Conclusion: The available literature revealed that technical difficulties such as appliance management, biomechanical limitations, and lack of training on the part of professionals have influenced the low use of this technique.

Introduction. Transverse deficiency or maxillary hypoplasia is one of the most harmful alterations for facial growth and the integrity of the dentoalveolar structures. To resolve this type of dentoskeletal alterations, rapid palatal expansion using mini screws (MARPE) has been proposed, which are placed in the palatine bone for transverse correction. In recent decades there has been a development of scientific evidence in dental specialties that is published as scientific articles and available in databases. However, researchers have not yet been able to demonstrate the possibility that much of the literature used in their search for new knowledge may present errors that affect the validity of the information. Objective. Assess and describe the quality of an article with high impact regarding the influence that rapid palatal expansion assisted with mini screws has on the airways and breathing in children and adolescents. Methodology. In a primary review in Google Scholar, the terms and logical connector (MARPE) AND (ADOLESCENT) were used, using as inclusion criteria only the Spanish and English language, that they were published between the years 2012 and 2022, only review articles and that they were related to maxillary transverse expansion assisted with mini screws in children and adolescents, in order to find the source of greatest impact, which was measured by the number of times it had been cited. Once found, he proceeded to analyze the bibliographic references of the main article (51) and evaluate what type they were. 27 sources were selected that could be evaluated using validated instruments such as CONSORT, STROBE and PRISMA, depending on whether they were randomized clinical trials, observational studies, or review studies, respectively. It was verified whether they complied with each of the parameters mentioned there. Results. In the primary search, a total of 657 articles were found; after selecting only those that met the inclusion parameters, 101 were retained. The one with the greatest impact, having been cited most frequently, was chosen as the main article. Of the 51 bibliographic sources in this study, 24 that could not be evaluated with the three instruments used (CONSORT, STROBE and PRISMA) were excluded. Of the 27 articles that were evaluated, 5 were randomized clinical trials, 15 were observational studies and 7 were reviews. None met 100% of the recommendations in the checklists. Conclusion. It is concluded that the main article referring to the influence that rapid palatal expansion assisted with mini screws has on the airways and breathing in children and adolescents, which is of high impact and cited by dozens of investigations, does not include bibliographic sources that comply 100% with the parameters established in validated instruments to evaluate scientific literature such as CONSORT, STROBE and PRISMA.

Introduction. RELI is a proposal for the application of the injected resin technique for the elaboration of lingual reducers, devices used during orthodontic treatment in patients who present anterior open bites due to atypical swallowing, making this malocclusion an overly complex case to solve. Its use is indicated when logopedic therapies have not had satisfactory results, for which the application of small painful stimuli on the tongue is used to cause an unconscious avoidance effect that allows the tongue to relocate in a physiologically adequate position, thus reestablishing the necessary balance that allows the free movement of the dental pieces, which is provided by the fixed orthodontic appliance. The resin injection technique has been used mainly in cases of dental esthetics for veneers and restorations, on this occasion I decided to apply it to the creation of lingual reeducators to enhance its benefits. Objective. The objective is to make known the protocol for the creation of lingual reeducators by means of injected resin technique, and all its benefits, multiplying its use in cases that require it, promoting the reeducation of the tongue, a particularly crucial factor to solve these malocclusions and avoid future recurrences. Methodology. Applying the scientific method, an applied field work was conducted with a qualitative approach of descriptive cross-sectional practical research. It was conducted in a 22-year-old female patient diagnosed with anterior open bite due to atypical swallowing, after previous acceptance by means of an informed consent. Results. The RELI protocol, due to its simple procedure, is easy to replicate by professionals even inexperienced in the subject, with relatively short working times in the dental chair as well as in the laboratory, it shows a high margin of precision at the moment of performing the indirect adhesion in the mouth, so it can be applied in daily practice, because it is economic and accessible, it can be reusable being easy to store and it does not require subsequent polishing, eliminating the risk of immediate fractures. Conclusion. The RELI protocol is a great alternative for the elaboration and placement of lingual educators in patients with atypical swallowing due to its numerous benefits. Its elaboration by means of soft acetates is easy to handle, has simplified and integrated steps, reducing work time for the patient and the professional.

Introduction.  Wandering atrial pacing is a benign atrial arrhythmia seen in elderly patients with obstructive pulmonary disease resulting from cardiac ischemia.  Objective. To determine the management and therapeutics of errant pacing in order to establish novel and instructive elements of the disease.  Methodology. Descriptive, retrospective, clinical case study. The technique used for the collection of the information of the case will be through the review of clinical history and for the description of the pathology will be through the compilation of articles extracted from recognized databases such as: Scopus, PorQuest, Pubmed, web of science, lilacs. Inclusion criteria: articles published in the last 5 years, in Spanish and English. The ethical criteria were met with the patient's informed consent.  Results. A 67-year-old male patient came to the cardiology outpatient clinic for cardiovascular evaluation, with a personal history of valvular heart disease treated with aortic valve implantation in 2016, extreme bradycardia and errant pacemaker. Conclusion. The patient's extreme bradycardia and errant pacing require continued dual-chamber pacing management. Regular follow-up visits with the cardiologist and pacemaker interrogations are essential to monitor pacemaker function, capture, sensing, and battery life. General area of study: medicine. Specific area of study: cardiology. Type of study: clinical cases.
