RESUMO

This in vitro study aimed to determine the flexural strength and modulus of elasticity of two bisacrylic resins for temporary crowns at different thicknesses, i.e., Structur 3 and Structur Premium, and to compare them with each other. Sixty samples were prepared, thirty of each material, which were made at different thicknesses (1 mm, 1.5 mm, and 2 mm). The dimensions followed the UNE-EN ISO 178:2019 standard, with a length of 24 mm, a width of 10 mm, and the thicknesses described. Materials were subjected to a three-point bending test. For the modulus of elasticity, statistically significant differences were observed between the 1.5 mm and 2 mm thicknesses of Structur 3 material. For Structur Premium, statistically significant differences were observed between the thicknesses 1 mm and 1.5 mm as well as between 1 mm and 2 mm thickness. With respect to flexural strength, no statistically significant differences were observed for either material at the different thicknesses. Significant differences were observed between the materials for both flexural strength and modulus of elasticity, being higher for Structur Premium: Structur Premium has a higher flexural strength and modulus of elasticity than Structur 3. There are significant differences for the modulus of elasticity but not for the flexural strength between thicknesses.

RESUMO

INTRODUCTION: Cervical cytology is a well-stablished cervical cancer screening method. However, due to the anatomical continuity of the genital tract, it can also detect signs of endometrial disease. Our aim was to estimate the sensitivity of cervical cytology in endometrial cancer detection and prognosis in a large population over a 30-year period in a large academic tertiary hospital in Spain. METHODOLOGY: We performed a search for women diagnosed with endometrial cancer from 1990 to 2020, who were surgically treated and had a previous cervical cytology result. Information Technologies Department databases from Bellvitge University Hospital and the Screenwide case-control study's database were used. Cervical cytology results were classified as abnormal when squamous lesions, glandular atypia or malignant cells were identified. RESULTS: Overall, we evaluated 371 women with endometrial cancer and a documented cervical cytology performed within 3 years previous to surgical treatment. Overall, the sensitivity of cervical cytology for endometrial cancer detection was 25.6%. Several clinico-pathological characteristics, such as non-endometrioid histology and a higher stage, were correlated with higher sensitivity. DISCUSSION: We observed a low sensitivity of cervical cytology to effectively diagnose endometrial cancer. However, recent technological advances using genomics and epigenomics may offer a promising perspective to detect endometrial cancer with high sensitivity in these cervical specimens.

RESUMO

OBJECTIVE: The objective of this study was to test whether or not there is an association between generalized joint hypermobility (measured using the Beighton score) and temporomandibular joint disk displacement in women who had sought medical attention for temporomandibular disorders (TMD). STUDY DESIGN: We studied 66 women who were attending the clinic for TMD. The patients were examined for joint hypermobility, and Beighton scores were calculated. When it was suspected that a patient suffered arthropathic complaints, magnetic resonance imaging of both temporomandibular joints was performed with the mouth closed and at maximal opening. The Pearson chi-squared test was used to test for an association between generalized joint hypermobility and disk displacement. RESULTS: We were unable to confirm the existence of an association between generalized joint hypermobility and temporomandibular joint disk displacement in women (chi(2) = 1.523; P = .02). CONCLUSION: Generalized joint hypermobility may be a factor related to TMD, but we did not find an association between generalized joint hypermobility and anterior disk displacement in women.

RESUMO

Sleep apnea and hypopnea syndrome (SAHS) is a disorder characterized by intermittent and repetitive obstruction of the upper airway provoking pharyngeal collapse. It is characterized clinically by a triad of daytime hypersomnia, snoring and pauses in breathing during sleep that are normally reported by the partner. Polysomnography is the chosen method for diagnosing this pathology. Patients with this disorder tend to have the following dental and orofacial signs: a retrognathic jaw, a narrow palate, a wide neck, deviation of the nasal septum and relative macroglossia, among others. Dentists should be ready to evaluate the risk-benefit of certain dental treatment options for this public health problem. The treatment of this problem will depend on its severity, with one of the options being the Mandibular Advancement Device (MAD) that is used especially in the treatment of slight or moderate SAHS and in the treatment of snoring, with results that are occasionally very successful. The objective of this study is to carry out an up-to-date literature review of SAHS and to evaluate the role of the dentist when faced with this pathology.

RESUMO

Analizamos una muestra de 102 pacientes procedentes de la Unidad de DTM de la clínica odontológica universitaria de la Universidad de Murcia y revisamos 110 historias clínicas de pacientes que asisten a la clínica odontológica universitaria y no presentan DTM: Las mediciones del ángulo mandibular se han realizado en las ortopantomografías trazando la línea que une los puntos más periféricos de la rama mandibular y del cuerpo mandibular. Hemos encontrado que el ángulo es mayor en los pacientes sanos que en los pacientes con DTM (p-valor= 0,00149). El ángulo mandibular es mayor en los pacientes de edad más avanzada y en los varones. Los pacientes con ausencia de molares posteriores presentan aumento en la angulación, al igual que los pacientes con clase 111 de Angle molar. En cuanto al grupo que presenta patologías de la DTM, se observaron ángulos mayores en los pacientes con alteraciones articulares y mixtas (AU)


This study analyses a sample of 102 patients from the Dental Clinic TMD Unit of the University of Murcia (Spain), and revise 110 clinic reports of patients attending the University dental clinic with no sign of TMD. The mea surements of the gonial angle have been determined from the orthopantomogram by drawing the line joining the furthest points of the mandibular ramus and condyle (rama y cuerpo). lt has been found that that the angle is greater in healthy patients than in those with TMD (p-value = 0.00149). The gonial angle is also greater in older patients and maleo Patients with no back teeth show again greater angle, as well as patients with type III teeth Angle. As regards the group with pathologies of the TMD, greater angles were observed in patients with articular and mixed disorders (AU)
