Item Desmitificando la evidencia científica, hacia su aplicación clínica(Universidad de Cuenca, 2018) Bravo Calderón, Manuel Estuardo; Abad Coronel, Cristian Gustavo; Reyes, GiuseppeItem Prevalencia y características del canal incisivo mandibular en cbct(Universidad de Cuenca, 2018) Muñoz Guartán, Carolina Lizzeth; Olivo Aguilar, Bryan Santiago; Pineda Álvarez, David ManuelObjetive: To determine the prevalence and characteristics of the mandibular incisor canal using cone beam computed tomography. Methodology: A descriptive and observational research was carried out. The sample consisted of 93 tomographies of the radiological center “Innova X-ray Facial Maxillus Facial” of the city of Cuenca in the period October 2016 - September 2017. The images were analyzed using the software i-Dixel 7.0.0.1, the information was collected in forms and was processed with the SPSS V.23 program. Results: The prevalence of mandibular incisor channel was 95.7% and was visualized mainly in males (97.5%). In 80.9% the position is bilateral, when unilateral, the prevalence is higher on the left side (12.4%). In both sexes, the bilateral channel is more frequent, especially in women (88%). Unilateral positions, either right or left, predominate in men (12.8% and 15.4%). The average channel dimensions were: (right/left) length: 8.59±3.40mm/ 9.07±3.30mm, maximum vertical diameter: 1.88±0.59mm/ 1.93±0.54mm and maximum horizontal diameter: 2.02±0.54mm/ 2.07±0.53mm). Conclusions: The prevalence of the mandibular incisor channel is high, with morphological characteristics in our population, which is why it is necessary to identify and assess it using cone beam computed tomography in each case in particularItem Fracaso anestésico del bloqueo del nervio alveolar inferior en pulpitis irreversible sintomática en molares inferiores y técnicas de complementación ante ésta eventualidad(Universidad de Cuenca, 2018) Kun Astudillo, Kenia KarenThe endodontic therapy especially in cases of symptomatic irreversible pulpitis is possible whenever there is a deep anesthesia. The failure rate of the technique for lower alveolar nerve block is high (44% -81%), which is why the clinician must consider the existence of multiple factors. Among them is mentioned the pH of the lesion area, the concentration of the anesthetic solution, the presence of cytokines or other mediators of inflammation as well as the patient's components such as stress, nervousness, individual variations. The objective of this literature review is to group the factors involved in the failure of the inferior alveolar nerve block, as well as to disclose the complementary techniques that are currently used to supplement this problem.Item Evaluación de la microfiltración en restauraciones indirectas de cerómero cementadas con: agente adhesivo dual, autoadhesivo y resina restaurativa precalentada(Universidad de Cuenca, 2018) Bucheli, María del Carmen; Mena Córdova, Nancy; Abad Coronel, Cristian Gustavo; Sandoval Vernimmen, Fernando RaúlThe purpose of this study was to evaluate the microfiltration in indirect ceromer restorations Ceramage A1 Body (Shofu), cemented with a dual adhesive agent RelyX ARC (3M ESPE); with a RelyX U200 self-adhesive (3M ESPE) and a Filtek Supreme Z350 pre-heated restorative resin (3M ESPE) for 10 minutes at 55 ° C. The sample consisted of 60 third molars, in which mesio-occluso-distal MOD cavities with 3 mm depth and width (inlays) were performed. Impression was made with addition silicone and the restorations were made. The samples were divided into groups of 20; the first group was cemented with dual adhesive agent, the second group with self-adhesive and the third with pre-heated restorative resin, following the manufacturer's instructions. All samples were photocured with Optilux 501 halogen light (SDS Kerr) at 1020 mw / cm2, for 40 sec. each surface , then were subjected to 10,000 cycles Introducción Las restauraciones indirectas en el sector posterior se han convertido en la mejor opción cuando la destrucción coronal es amplia y compromete una cara proximal, ya que las restauraciones directas tienen mayor índice de contracción, formando espacios entre la interfase de la estructura dental y la resina, dando paso a la microfiltración, siendo éste un fenómeno dinámico que provoca pigmentación marginal, caries secundaria, sensibilidad post operatoria, lesiones pulpares, y fallas en la adhesión (1) (2) (3). Es así que el uso de restauraciones indirectas se popularizó a partir de 1980, ya que presentan mayor control en su polimerización, por lo tanto mejor contorno anatómico y proximal, estética y cualidades de pulido (4) (5). Su uso está indicado cuando no hay paredes proximales, cuando la altura del piso a cúspide es de 1.5-3 mm o cuando la medida entre cúspides es la mitad de la totalidad de las misma. (6) Uno de los varios materiales que se utilizan en una restauración indirecta es el cerómero, por su biocompatibilidad, sin embargo la técnica de cementación se vuelve un protocolo susceptible. En el mercado existen diferentes tipos de cemento a base de resina que han probado tener una alta resistencia en restauraciones de composite; ya que se caracterizan por ser resilentes, tienden a deformarse y a absorber fuerzas de tensión. (7) (8) of thermocycling and submerged in 2% basic fuchsin for 24 hours at room temperature. Macro- photographies were taken of the MOD surfaces and marginal microfiltration was evaluated in ranges from 0 to 4 between the inlays and the dental structure; 0 being the one that does not present any pigmentation and 4 presence of cracks. It is concluded that the samples that have lower marginal microfiltration are cemented with preheated restorative resin, followed by cemented with the dual adhesive agent and finally those cemented with self adhesive. In addition, the surface with the lowest microfiltration was the occlusal, followed by the mesial and finally the distal surface in all casesItem Hiperplasia Fibrosa Inflamatoria.

Reporte de un caso clínico(Universidad de Cuenca, 2018) Guamán Quintuña, Jaime Luis; Astudillo Ortiz, Jaime LeonardoItem Equipo portátil de rayos x: aplicación en el área odontológica(Universidad de Cuenca, 2018) Romero Rodríguez, Valeria Paulina; Pesántez Alvarado, Juan MartínPortable dental x-ray units have been widely used in disaster situations and dental care in patients with limited mobility, for their easy-handling and transport, their specific characteristics make them suitable tools for routine dental practice, such as small size, wireless operation and cost reduction in terms of infrastructure. Despite its advantages, exposure to ionizing radiation suffered by the operator should be considered, there will be a negligible increase in exposure levels when using these devices but remaining below the recommended levels. However, they could represent an increase in what a zero exposure should be when using a fixed device. To properly apply the radiological protection norms and to use personal dosimetry, will reduce the risks of biological effects in the exposed professional when performing a radiological safe practiceItem Actividad antimicrobiana de las pastas antibióticas a través de los tejidos dentales(Universidad de Cuenca, 2018) Rodas Rodríguez, Claudia Judith; Mendoza Trejo, Roberto Carlos; García González, Rafael; Yamamoto Nagano, Jesús Adolfo; Cárdenas Vidal, Fernanda de LourdesThe purpose of this study was to evaluate through an experimental study in vitro the antimicrobial activity of antibiotic paste, in this case CTZ modified with Clindamycin. Materials and methods. The study was conducted with premolars and third molars divided in three groups, the first group were filled with zinc oxide and eugenol, for the second group the CTZ paste for sealing was used, and the third group CTZ paste was used but with prior instrumentation of teeth. Results. In the first group no inhibition zone was observed. For the second and third group halo of inhibition existed on the periphery of the teeth. Conclusions. The use of CTZ paste has a degree of permeability and bacterial inhibition. The use of zinc oxide and eugenol did not show permeability and bacterial inhibition.Item Prevalencia de complicaciones durante la exodoncia en la Universidad de Cuenca(Universidad de Cuenca, 2018) Bustos Castellano, Andrea Tatiana; Morales González, Karla Estefania; Pineda Álvarez, David ManuelThe research was carried out with the objective of determining the prevalence of complications during simple exodontia in patients at the Facultad de Odontología de la Universidad de Cuenca. A form was used that contains general data of the patient and specific of each complication. The results showed a prevalence of complications of 42.5% corresponding to 120 teeth, the upper molars (43.2%) showed a higher prevalence of complications during the simple extraction procedure. The pain (56.9%) and the tooth fracture to extract (45.1%) were the most frequent complications. No teeth were found that had suffered complications of displacement of the tooth to the maxillary sinus and of intraoperative hemorrhage
