    Comparación de la eficacia de fibra de polietileno versus composite reforzado con fibra corta como sustitutos de dentina en dientes tratados endodónticamente. Revisión narrativa
    (Universidad de Cuenca, 2025-09-18) Llapa Yuquilima, Carla Cecilia; Iñiguez Matute, Wendy Dayanna; Alvarado Jiménez, Omar Ricardo
    In dentistry, fiber-reinforced materials present various applications, especially in the restoration of endodontically treated teeth. Among these, short fiber-reinforced composites (SFRC) and polyethylene fibers (PF) are used as substitutes for dentin structure to improve the physical properties of dentin. Objective: to evaluate the efficacy of polyethylene fiber versus short fiber-reinforced composites as dentin replacement materials in endodontically treated teeth (EET). Methodology: A narrative review was performed by searching for articles related to polyethylene fibers and short fiber-reinforced resin composites published between 2013 and 2024. The databases consulted were PubMed-MEDLINE, Google Scholar and Scopus. A total of 34 relevant studies were selected that aligned with the aim of the present article, including in vitro studies, systematic reviews, and narrative literature reviews. Conclusion: The studies reviewed indicate that glass fiber-reinforced resins offer greater fracture resistance, integrity, and clinical longevity than polyethylene fibers. This makes them an effective alternative as a dentin replacement material for endodontic teeth.

    n the context of diagnosing and planning treatment for patients with dentofacial deformities, it is crucial to examine the upper airway, as its function may be compromised by the facial skeletal pattern or impacted by planned surgical intervention. Cone Beam Computed Tomography (CBCT) is positioned as the preferred option for evaluation due to its precision and ability to predict possible changes. Objective: to evaluate the volume of the upper airway in different facial skeletal patterns of a population ofstudents from the University of Cuenca at TCHC. Materials and methods: 33 tomographies were evaluated through the Sidexis 4 program, where the volume of the nasopharynx, oropharynx, and hypopharynx was measured according to facial skeletal pattern and sex. Results: Of the 33 CBCT analyzed, 10 (30%) belonged to males and 23 (70%) to females. Within the population of patients with skeletal class I, it was found that the volume of the oropharynx was greater compared to the nasopharynx and hypopharynx, thus obtaining an average of 21.87 cm3, with a standard deviation of 5.09. Conclusions: The average volume of the upper airway in subjectswith Class I facial skeletal patterns is higher than in Class II, thus being statistically significant in the oropharynx. It is recommended to conduct studies with a larger population involving Class III skeletal patterns.
