El propósito de la presente revisión bibliográfica es la presentación de alternativas para el tratamiento de las maloclusiones de clase III. Para lo cual se realizó una búsqueda de artículos científicos y reportes de casos clínicos de esta maloclusión, en diversas revistas cient íficas de ortodoncia y ortopedia. Concluyendo que se debe realizar un buen diagnóstico esquelético y dental que permita la diferenciación entre las maloclusiones clase III de origen dental o de origen esquelético, y de esta forma enfocar el plan de tratamiento de acuerdo a la edad del paciente y origen de la misma.Cuando son de origen dental se cuenta con alternativas como planos inclinados de oclusión, arco de Eschler o arcos de protrusión que permiten interceptar el problema antes de que se desarrolle una maloclusion esquelética. Al ser de origen esqueletal el tratamiento es encaminado a resolver el problema, por medio de aparatos extraorales que produce un crecimiento diferencial del maxilar o mandíbula que son las causantes d e estas displasias. En pacientes que han terminado el crecimiento se tiene dos alternativas de tratamiento, una es la compensación dentaria (camuflaje) mediante la proinclinación de los incisivos superiores y retroinclinación de los inferiores sea mediante distalización o extr acciones en el arco inferior; la otra alternativa es la combinación de ortodoncia con cirugía cuando la discrepancia maxilo mandibular es grande.PALABRAS CLAVE: Maloclusión clase III, tratamiento, pseudo clase III, protracción maxilar, mentonera, camuflaje, ortodóncico quirúrgico. SUMMARYThe purpose of this literature review is to present alternatives for the treatment of Class III malocclusion. For which a search was conducted of scientific articles and clinical case reports of this malocclusion in various magazines orthodontic and orthopedic. Determini ng that should make proper skeletal and dental diagnosis to differentiate between class III malocclusions of skeletal origin or dental origin, and thus focus the treatment plan according to the patient's age and origin of it. When they are of dental origin there are alternatives such as inclined planes of occlusion Eschler arc or arcs that allow protrusion to trap the problem before it develops a skeletal malocclusion. As origin of skeletal treatment is aimed at solving the problem, through extraoral devices that produce differential growth of the maxilla or mandible that are responsible for these dysplasias. In patients who have completed growth has two treatment alternatives, one is the dental compensation (camouflage) by proclined upper incisors and lower retroclined either by distalization or extractions in the lower arch, the other alternative is the combination of orthodontic surgery when maxilla mandibular discrepancy is large.

Objective: The purpose of this study was to determine the intensity of the light power and the integrity of the active part of the curing lights of the Faculty of Dentistry Clinic of the University of Cuenca in the March-August 2022 term. Lack of knowledge of light-curing units, leads dentists to purchase low-quality equipment, thinking that they all work with the same efficiency, compromising the long-term success of restorations. Therefore, it is important to know the ideal characteristics of a light-curing lamp. Materials and methods: This is a descriptive and observational study whose sample is made up of 72 light-curing lamps assigned by the clinic and the lamps of each student who is attending the clinic. For the development of the project, a radiometer was used. Results: Of the 72 lamps analyzed, 54 (75%) are LED devices and they correspond to the students. Of which, 47 (87.03%) are effective because they have a power greater than 800 𝑚𝑊/𝑐𝑚2. On the other hand, the 18 (25%) are part of the cabin group, in this case there are 15 halogen devices (83.33%) and 3 LED devices (16.67%). Of which, 3 (20%) halogen lamps are effective, while 1 (33.33%) LED device is effective with a power greater than 800 at 𝑚𝑊/𝑐𝑚2. Conclusion: An adequate polymerization is crucial to obtain good mechanical and physical properties and excellent clinical results of the material.

The purpose of the present review was to describe the numerous alternatives for the treatment of facial asymmetry caused by condylar hyperplasia and compare the results obtained in both aesthetic and functional aspects. A search for articles published from 2002 to 2017 in the PubMed and Lilacs databases was realized. A total of 42 articles were selected according to the inclusion criteria, of which 32 were used for the study. The selection of the most appropriate treatment for condylar hyperplasia depends on factors such as the age of the patient, degree of deformity, osteoblastic activity of the condyle, etiology and functional limitations. The procedure of first choice when confirming active growth of the condyle will be condylectomy in combination with orthognathic surgery. Condylectomy is essential in the presence of joint problems and tumors. The treatment with condylectomy as well as orthodontic camouflage through the use of mini-implants can be considered in cases of mild asymmetry.

Background: The clinical teachers create a learning environment that integrates the theoretical knowledge learned in classrooms and laboratories, therefore the student, having a teacher who provides everything he/she needs to become an excellent professional will always be very indispensable. Knowing how students perceive the quality of their teachers can in turn reveal their strengths and weaknesses, and make changes if necessary. The objective of this article is to evaluate the students' perception of the performance of the clinical teachers of the faculty of Dentistry of the University of Cuenca during the academic year 2021-2022. Methods: Analytical study, which involved the participation of 97 students who responded to a survey at the Faculty of Dentistry of the University of Cuenca, Ecuador. For the present study, a scale was used to evaluate the responses to the instrument, the objective of which was to determine the students' opinion of the clinical dental education provided by clinical teachers. The scale assessed six dimensions: modeling, coaching, scaffolding, articulation, reflection and general learning from the environment. Results: The general result indicated a neutral perception, the majority of the students are unbiased with a slight tendency to "partially agree”, however this depends on each dimension. Conclusion: For the students' impartiality, it is important to provide feedback to the clinical teachers in order to improve and implement new methodologies that allow the student to guarantee a professional training with the full support of their teacher.
