Several cleaning methods have been proposed for dentures that help prevent stomatitis and other soft tissue injuries and that fulfill their bactericidal and fungicidal function, in addition to having the ability not to alter the physical and mechanical properties of the denture base and of the dentures or artificial teeth. Objective: to determine the efficacy of desinfection methods for the elimination of Candida Spp. in removable dental prostheses Material and methods: A bibliographic review was carried out that consisted of the search for scientific articles in databases such as: Web of Science, Scielo, Scopus and PubMed. Results: The initial search send a total of 25 articles and by applying inclusion and exclusion criteria, 19 were selected. Conclusions: chemical mechanical methods, antiseptic soaps and photodynamic therapy have an efficacy of over 80% to eliminate Candida. albicans with short prosthesis immersion times of between 3 and 15 minutes.

Objective: To determine the inhibitory effectiveness of Garlic extract (Allium Sativum) and Green Tea (Camelia Sinensis) on Streptococcus Mutans at 24 and 48 hours. Material and methods: Quasi-experimental, prospective and longitudinal study. The sample consisted of Streptococcus Mutans strains isolated from the dental plaque of patients with prior consent and inoculated in 20 Petri dishes on Blood Agar with 60 replicates for each treatment and a positive and negative control for each plate. Garlic (Allium Sativum) and Green Tea (Camelia Sinensis) extracts were obtained by the maceration and evaporation method. The positive control was 0.12% chlorhexidine and the negative control was distilled water. The inhibitory effect was measured by the Kirby Bauer and McFarlad method. Inhibition halos were observed at 24 and 48 hours. Data analysis was performed with t and Tukey statistical tests. Results: The best inhibitory effect is recorded by Garlic extract (Allium Sativum) at 100% at 24 hours with an average of 15.67mm of inhibition halo compared to Green Tea (Camelia Sinensis) at 100%, which obtained an average of 14.18mm . Conclusions: The extract of both plants have inhibitory effect in vitro against strains of Streptococcus Mutans. Garlic extract (Allium Sativum) has a greater inhibitory effect in relation to Green Tea (Camelia Sinensis) both at 24 and 48 hours. The active principle of both extracts is reduced after 48 hours, therefore also an inhibitory effect.

Objective: To determine the prevalence of pulp necrosis in patients from 20 to 40 years old treated in the Ministry of Public Health zone 7 of Ecuador during 2017-2020. Establish the population distribution sample based on age, sex, and location. Materials and methods: Descriptive, document-based, cross-sectional study. The population and sample of the research were the patients' records that have been treated at the dentist area in the healthcare facilities registered in the Ecuadorian Zone 7 from 2017-2020. Results: The prevalence of pulp necrosis in Zone 7 is 11.597 of users in all three provinces where the province of Loja presented a higher incidence of 5303 dental care patients presented this diagnosis and where the age range with the highest number of cares was 20-30 years of age, in terms of sex it was possible to show that the percentage of dental care in women is greater than that of men in relation to the 3 provinces that correspond to zone 7 during the 2017-2020 period, in each year respectively, thus having a significant statistical value compared to the male sex. Conclusions: It was determined that the prevalence of pulpal necrosis in zone 7 of Ecuador has a low percentage of incidence, so we must continue to emphasize oral health.

Introduction: Class III malocclusion is considered the third oral health problem after caries and periodontal disease, according to the WHO. Dental class III is related to mandibular prognathism, which is characterized by a mandible with vertical growth. For this reason, it is necessary to make an early diagnosis of the eruption of the first permanent molars and canines, which determine the key to occlusion. The treatments can be interceptive using functional orthopedics and corrective with orthodontic-surgical treatment. Objective: To determine the cephalometric changes in patients with mandibular prognathism and pseudo prognathism pre and post-surgery. Materials and Methods: This research work has a qualitative approach, the type of research is retrospective because information already published in previous years was obtained; and cross-sectional because the data was collected in a single period making a cut in time. The research design is descriptive-observational, NOT experimental, because it is carried out without deliberately manipulating variables. It is a systematic review in which metasearch engines such as: Google Scholar, Pubmed, Scielo, Medline were used, by inclusion and exclusion criteria 40 related articles were left. Results: Mandibular pseudoprognathism is the product of multifactorial alterations that influence dentoskeletal development, which must be corrected early with functional orthopedics and ortho-surgically after calcification of bone growth centers. The diagnosis and post-treatment control must be clinical and radiographic. Conclusion: Pseudoclass III disharmony tends to worsen with growth, so early orthodontic intervention is necessary to prevent true prognathism before growth of the craniofacial skeletal sutures is completed.

Introduction: Clefts of the lip and/or palate are the most common congenital malformations, with a high incidence and prevalence worldwide. The treatment of these begins immediately after birth, until adolescence, even into adulthood, through multiple pre-surgical, surgical and post-surgical interventions. Objectives: The objective of this study was to evaluate, through a literature review, the etiology, diagnosis and treatment of cleft lip and/or palate in neonates and infants. Materials and Methods: A search was performed in electronic databases: ScienceDirect, PubMed, SciELO, Google Scholar, and the reports of the World Health Organization (WHO), American CleftPalate platforms (ACPA) - Craniofacial Association Centers for Disease Control and Prevention, WebMD, and the Rare Disease and Orphan Drug Information portal. The search was restricted to articles in English and Spanish, published from 2011 to 2021. Results: After applying the inclusion criteria, a total of 35 articles were obtained and reviewed. A review of the literature on the etiology, diagnosis and treatment of cleft lip and/or palate in neonates and infants was carried out. Conclusions: The authors consider that the main etiology of cleft lip and palate is unknown; however, there are various genetic and non-genetic risk factors. Diagnosis is made by ultrasound examination at 20 weeks of intrauterine life, and coordination of multidisciplinary teams is essential to guarantee the best results.

Introduction: Among the most used materials for direct restorations, we have composite resin and silver amalgam. The objective of this work is to identify the restoration that has the greatest effectiveness and durability between amalgam and resin in the mouth. Methodology: Several articles in Spanish and English published from 2000 to 2020 were selected; the search was carried out in PubMed, Medline, Science Direct, Elsevier, Cochrane. 100 articles were reviewed and 30 were selected including meta-analyzes, systemic reviews, clinical trials, randomized controlled trials, in vitro studies Results: The main cause that affects the durability and effectiveness of composite resin is secondary caries, while in amalgam it is the fracture. Conclusion: Composite resin and amalgam restorations have several advantages and disadvantages. Currently the material of choice for direct restorations is composite resin due to its excellent properties such as its high aesthetics; on the other hand, amalgam has greater durability, however, due to its disadvantages, it is no longer the main material of choice.

Introducción: El defecto de furca se define como la destrucción de los tejidos de soporte dental de piezas multirradiculares, enfatizando en la perdida de inserción del espacio interradicular y la reabsorción ósea, la cual resulta de la enfermedad periodontal asociada a placa bacteriana. Este defecto permitirá un acceso limitado tanto clínico como visual del área afectada, ocasionando una compleja intervención por el especialista. Objetivo: Determinar la prevalencia de factores de riesgo de lesiones de furca en pacientes de la clínica odontológica de la Universidad católica Santiago de Guayaquil. Materiales y métodos: Se obtuvieron un total de 66 furcas, las cuales fueron sometidas a un proceso de criterios de inclusión y exclusión, para poder ubicarlos en la tabla madre para analizar los factores de riesgo de las furcas dentales.  Resultados: En el presente estudio se obtuvieron 66 furca, en relación al género se obtuvo 20 (30,30%) pacientes femeninas y 46 (69,70%) pacientes masculinos. Con relación a la furca Grado I 52 (78,79%), 18 (19,70%) en pacientes femenino y 34 (51,52%) en pacientes masculinos. Grado II 13 (19,70%), 2 (3,03) en pacientes femeninas y 11 (16,67) en pacientes masculinos.  Grado III 1 (1,52%), en paciente masculino. Conclusión: De las muestras estudiadas, podemos determinar que los factores de riesgo, que mayor prevalencia presentaron, fueron el de placa bacteriana, estadio periodontal, fenotipo periodontal, longitud de tronco radicular y anatomía radicular.

With the increasing number of adult patients seeking orthodontic treatment, orthodontists are increasingly faced with the risk of periodontal problems. Likewise, it is known that inadequate orthodontic movement can result in root positions outside the alveolar cortices, bone dehiscence, and root resorption. In addition to the fact that inadequate removal of bacterial plaque causes damage to gingival tissues such as caries and gingivitis. Coordination between orthodontists, periodontists, and general dentists is helpful in preventing and stopping periodontal disease. Objective: The objective of this bibliographical review is to analyze the effects of orthodontic treatments on periodontal tissues, as well as the degree of severity according to the movements made by the orthodontist. For this, a search was carried out in the Medline and Pubmed databases, obtaining a total of 31 articles. It is limited that orthodontic dental movement can induce root resorption, especially in intrusion movements that cause four times more root resorption than extrusion. , incisor intrusion and inclination of the maxilla can increase the degree of alveolar bone loss, in the same way the risk of root resorption or gingival recession is greater in adult patients than in young people.

INTRODUCTION: Among the diagnostic tests to evaluate sagittal maxillomandibular skeletal discrepancies and the different changes that occur during growth, the following are presented: ANB angle, (Riedel 1948); the Wits Assessment, (Jacobson 1975) of linear type and the A:B Ratio (Terreros 2020), study of geometric proportions, as alternative diagnostic tests to establish the intermaxillary sagittal relationship. OBJECTIVE: To analyze the correlation of intermaxillary sagittal appreciation between angular diagnostic tests (ANB), linear (WITS) and A:B ratio (geometric proportional) in different facial types. MATERIALS AND METHODS: Comparative radiographic study with a quantitative, cross-sectional, retrospective approach in search of 55 cephalometric radiographs of boys and girls aged 8 to 13 years, descriptive-analytical design study, deductive method. RESULTS: In this study it was shown that between the ANB Angle and the A:B Ratio there is a moderate negative relationship of -0.59, between the Wits assessment and the A:B Ratio the correlation is -0.504, which indicates that there is a moderate negative relationship and Angle ANB with the Wits Rating the value is 0.501 which indicates that there is a moderate positive correlation. CONCLUSION: It is established that the ANB angle diagnostic test uses the Nasion point as a reference and that its position affects its diagnosis. There is a moderate to good correlation between the diagnostic tests ANB Angle, A:B Ratio and Wits Assessment in the determination of the intermaxillary sagittal relationship.

In Mexico, impunity began its genesis with the formation of the 20th century presidential system. The government structures rooted the vertical power of the president, making him omnipotent, benefiting his collaborators and subordinates, covering each other, in the justifying framework of the non-reelection. This power generated impunity for friends and family, which is why it was decided that the democratic alternation between groups close to the president and his party would allow them to preserve privileges and impunity; events that shaped regional and local chiefdoms. In the 21st century, non-reelection was changed to reelection, which generated the perpetuation of groups in power, a fact that was hidden in the justification of the professionalization in some positions popularly elected. These practices of power before and now prevent true democratic renewal because they are the niche where the mafias that use public money, influence trafficking and the factious use of institutions for personal purposes hide and operate, making it clear that criminality Dorada is real and its practices from the highest levels of government with ties to the outside, strengthen criminal sectors that escape, dilute and mock justice, democracy and collective well-being.
