    Alteraciones pulpares en molares temporales, producidas porobturaciones con ionómero de vidrio hasta el límite amelodentinario, en pacientes de la Clínica de Odontopediatría 2013/ 2014
    (2014) Idrovo Heredia, Gabriela Elizabeth; Vásquez López, Alvaro Esteban; Moreno Morejón, Gladys Eugenia
    The glass ionomer is now widely used in clinical pediatric dentistry as restorative material to present biocompatibility with dental tissues; studies (López, 2004) mention that restorative materials can cause pulpal alterations, but it is becoming less common, and these are due to a poor seal and marginal leakage. In this research, a clinical and radiographic examination of 44 primary molars sealed with glass ionomer was performed to dentino-enamel junction in children between 4 and 9 years of age who presented to the Faculty of Dentistry at the University of Cuenca; also monitored at 3 and 6 months after the sealing was performed. During the first test (3 months) no pulp injury was found by clinical and radiographic diagnosis in any molar studied (100%); in the second control (6 months) found that 9.2% of the total molar pulp alterations examined were: 4.6% had reversible pulpitis, irreversible pulpitis and 2.3% pulp necrosis also corresponded to 2.3%

    Prevalencia del conducto medio mesial en primeros molares inferiores permanentes mediante evaluación tomográfica computarizada de haz cónico disponibles en el departamento de imagenología de la Facultad de Odontología de la Universidad de Cuenca. 2015-2023

    Introduction: Generally, the lower first molar presents three root canals (CR): two mesial (M) and one distal (D); however, it may present an additional RC in the distal root, an isthmus within the mesial root, or a third canal in that root known as the mesial medial canal (MMC). Objective: To determine the prevalence of the MMC in permanent lower first molars evaluated through Cone Beam Computed Tomography (CBCT) available in the Imaging Department of the School of Dentistry at the University of Cuenca (UC) during the period from 2015 to 2023. Materials and Methods: The analyzed CBCTs were 517 (1034 teeth); to improve spatial resolution, the Zoom Reconstruction function was used, establishing a voxel of 160 μm and a field of view (FOV) of 50 mm x 50 mm. The image was oriented in the three planes: axial, sagittal, and coronal, according to the longitudinal axis of the mesial root, and in the axial cut, an initial path was traced from the cervical third to the apical third to determine its presence or absence; in case of its presence, the molar in which it was located was established. Results: The prevalence of the MMC was 11.22%, with the tooth 3.6 having the highest prevalence. Conclusions: The prevalence according to the participants' sex did not show a statistically significant difference, but regarding age, the results showed significantly different data, with the younger group having the highest prevalence.
