(Universidad de Cuenca, 2016) Jimbo Cazar, Ana Cristina; Pesántez Coronel, Amanda Isabel; Cazar Almache, Marcelo Enrique; Guillén Guerrero, Paúl Fernando
The present study supports the anatomical determination of the mandibular canal in adults of the Surgery Clinic ofthe Faculty of Dentistry ofthe University of Cuenca, this study has big importan- ce considering the location of the Canal in the performance of some surgical procedures such as collocation of dental ¡mplants, osteotomies, osteogenic distraction and the reduction of fractures and complicated extractions avoiding injuries to the mandibular nerve. The objective of the present study is to determine the location of the mandibular canal in relation to structures of importance in adults of the surgery clinic of the Faculty of Dentistry of the Univer- sity of Cuenca. The study’s sample was 50 adults of the Clinical Surgery of University of Cuenca. Patients were ¡n age of 18 to 35 years who meet the inclusión criteria. The study used the Cone Beam system. In the results, in the man the dental apex closest to the mandibular duct was of the molar 4.8, as in the woman, with respect to the posterior edge of the branch in men was a distance of 18,196 mm and in the woman of 16,177 mm. In the literatura is well documented the injury to the inferior dental nerve by the proximity of the ápices of the third molars with this nerve, in this study is coincided with this, since the ápices of the third molars are the closest to the inferior dental nerve.
Distancia entre los ápices del segundo molar y el piso del seno maxilar mediante tomografías computarizadas enero 2019 - septiembre 2020

Introduction: The maxillary sinus (MS) is a structure of great interest due to its proximity to the posterior superior dental structures (1). Knowing the distance between these structures is essential when performing pre-surgical planning (2), especially in case of the second molar due to its proximity to the maxillary sinus floor (MSF) (3–7). Objectives: Determine the distance between the apices of the second molar and the maxillary sinus floor using cone beam computed tomography. Methodology: Computed tomography scans were collected from a radiological center in Cuenca (January 2019 - September 2020). Using the Sydexis 4 software version 4.3, the apico-sinus distance was measured in a coronal cut section. The data collection was carried out using a template and the results were analyzed in the IBM SPSS program. Results: The average value of the apico-sinus distance was 0.45mm, 1.36mm and 2.36mm for the mesiobuccal, distobuccal and palatal roots on the right side. On the left side the values were 0.16mm, 0.66mm and 1.12mm respectively. In both cases the mesiobuccal root was the closest to the MSF. Conclusions: The mesiobuccal root of the second molar has the closest relationship with the MSF. Regarding the age group, the shortest distance is observed in group 3 (right side), and group 2 (left side). According to the sex, the average value is similar in the two groups.
Extracciones múltiples en el contexto del Covid-19: reporte de caso clínico de un cuarto molar
(Universidad de Cuenca, 2022-10-18) Román Alvarado, Liseth Carolina; Zhingre Suárez, Mauricio Rubén; Guillén Guerrero, Paúl Fernando
Abstract: The fourth molar, also called distomolar or retromolar due to its location distal or posterior to the third molars, is a variant of number and shape that occurs during odontogenesis. By means of the present clinical case, a 22-year-old female patient who attended the dental office of the University of Cuenca School of Dentistry was treated, with the need to have her third molars extracted in a single appointment due to the limitations of COVID-19 and in which the presence of a fourth molar was found in the radiographic exploration. Within the procedure, the osteotomy technique was used for the surgical extraction of the fourth molar in order to prevent displacement towards the maxillary sinus, in addition, the supplementation of antibiotics to analgesic therapy was considered to minimize possible postoperative complications. After the surgical procedure, consultative teleodonto-logy follow-ups were carried out by means of a telephone call in order to supervise the adequate intake of medications and verify the evolution of the patient
Inclusión dental ectópica: una revisión de la literatura
(Universidad de Cuenca, 2022-11-01) Chimborazo Buestán, Katerine Paulina; Maldonado Cruz, Alberto Jherel; Guillén Guerrero, Paúl Fernando
Objective: Analyze the publications on ectopic dental inclusion, as well as its risk factors, prevalence and respective treatments. Materials and methods: A literature review was carried out including articles from the year 2000 to 2021 in the databases: Medline/PubMed, SciELO and Google Scholar. Thirty-seven bibliographic references of interest were used for the study, of which 18 case report and case series articles were selected for the analysis of clinical, pathological, and radiographic information, as well as patient demographics, anatomical location of ectopic teeth, clinical symptomatology, and treatment modalities. Results: It was determined that the dental group with the highest incidence is the third molar with 68%, followed by canines with 12%, while the remaining 20% is comprised of: second molar, second premolar, supernumerary and unspecified tooth. The prevalence in relation to gender refers to 68% in women and the most common age range of its diagnosis is the third decade of life in 40%. Regarding associated lesions, 40% correspond to dentigerous cyst, 16% to granuloma, 28% without associated lesion, 4% radicular cyst and the remaining 12% do not mention lesion. The treatment for a patient with ectopic dental inclusion varies depending on its presentation characteristics, but it is usually resolved through a surgical approach and periodic radiographic clinical controls. Conclusion: Ectopic dental inclusion has a prevalence of appearance in the third decade of life, usually when patients present symptoms and before routine radiographic examination, the most satisfactory treatment is the intraoral approach, finally the prognosis in these patients is satisfactory.
Manejo de la extracción dental en pacientes sometidos a terapia anticoagulante: una revisión de la literatura
(Universidad de Cuenca, 2021-04-27) Yamunaqué Vire, Jessica Micaela; Merchán Reyes, Freddy Xavier; Guillén Guerrero, Paúl Fernando
In recent years the teeth extraction in patients who consume anticoagulants has increased, and with it also the need for new studies that allow us to know how to address such cases. Oral anticoagulant therapy is used to prevent thromboembolic type diseases. Among anticoagulants we have Vitamin K Antagonists and direct oral anticoagulants. The objective of this study is to analyze the type of management that an anticoagulated patient needs, in addition to the limitations, indications, and hemostatic measures for dental extraction in these patients. A search was made in the digital databases of Pubmed, Science Direct, Cochrane and SciELO, obtaining a total of 2176 articles that after the implementation of inclusion and exclusion criteria resulted in 59 articles for this literature review. The management in these patients should be done with extreme caution taking into account their systemic state, the extraction will be done safely without suspension or modification of the drug, when the surgical intervention has been planned with an atraumatic technique of one to three pieces and the INR is ≤3.5. It is essential for the dentist to have updated knowledge of the treatment of anticoagulated patients and their bleeding complications.

Background: Have not been found other studies that demonstrate the prevalence of mandibular asymmetry in the city of Cuenca-Ecuador. All people present a certain degree of asymmetry, but when it is in a marked form, it can be corrected with orthodontic treatment or in other occasions accompanied by orthognathic surgery (1). Objective: Determine the prevalence of mandibular asymmetries in cone beam computed tomography (CBCT) of patients who attended in the radiological center of the Odontology school of Cuenca city, Azuay, Ecuador from August 2015 to November 2018. Materials and methods: A cross-sectional descriptive study that included a universe of two hundred and sixty (260) cone beam computed tomographies, it obtained from the archives of the Odontology school of the city of Cuenca, Azuay, Ecuador. The mandibular asymmetry was determinate with the Habets method, which applied 3 formulas to stablish the index of condyle mandibular ramus asymmetry and total mandibular asymmetry. Index results above 3% indicate asymmetry. Results: In total mandibular asymmetry the prevalence was 37.80% in 68 of 180 CBCT, in mandibular ramus asymmetry was 43.90% in 79 of 180 CBCT and in condylar asymmetry the prevalence was 82.20% in 148 of 180 CBCT. Conclusions: The prevalence of mandibular asymmetry of patients who attended the radiological center of the Odontology School was low. It was found a high prevalence of condylar asymmetry index and a low prevalence of the mandibular ramus asymmetry.
