Influence of Aldehyde Dehydrogenase Inhibition on Stemness of Endometrial Cance...
Serambeque, Beatriz; Mestre, Catarina; Barros, Gabriela; Marques Teixo, Ricardo Jorge; Marto, Carlos Miguel; Gonçalves, Ana CristinaPublisher Copyright: © 2024 by the authors.; Endometrial cancer is one of the most common gynaecological malignancies. Although often diagnosed at an early stage, there is a subset of patients with recurrent and metastatic disease for whom current treatments are not effective. Cancer stem cells (CSCs) play a pivotal role in triggering tumorigenesis, disease progression, recurrence, and metastasis, as high aldeh...
Effect of varying functional monomers in experimental self-adhesive composites:...
Ferreira, Marta Nunes; Neves Dos Santos, Marta; Fernandes, Inês; Marto, Carlos Miguel; Laranjo, Mafalda; Silva, Diana; Serro, Ana PaulaThe aim was to evaluate the effects of adding different functional monomers to experimental self-adhesive composites (SACs) on polymerization kinetics, cell metabolic activity, and sealing ability. SACs were formulated using urethane dimethacrylate as the base monomer and triethylene glycol dimethacrylate. Additionally, 10 wt.% of distinct functional monomers were added - 10-methacryloyloxydecyl dihydrogen phos...
Three-Dimensional Pulp Volume Analysis in Lip and Palate Cleft Population
Francisco, Inês; Travassos, Raquel; Marques, Filipa; Ribeiro, Madalena Prata; Rodrigues, Mariana; Quaresma, Patrícia; Caramelo, FranciscoAim: Cleft lip and palate (CLP) patients have a greater predisposition to tooth malformation, which could affect pulp volume. The aim of this study is to evaluate the dental pulp volume of central incisors in 3D images between individuals with and without CLP. Materials and Methods: This retrospective case-control study is single-centered and was recruited between January 2016 and October 2022. Ninety-four pati...
Three-Dimensional Impression of Biomaterials for Alveolar Graft: Scoping Review
Francisco, Inês; Basílio, Ângela; Ribeiro, Madalena Prata; Nunes, Catarina; Travassos, Raquel; Marques, Filipa; Pereira, Flávia; Paula, Anabela BaptistaCraniofacial bone defects are one of the biggest clinical challenges in regenerative medicine, with secondary autologous bone grafting being the gold-standard technique. The development of new three-dimensional matrices intends to overcome the disadvantages of the gold-standard method. The aim of this paper is to put forth an in-depth review regarding the clinical efficiency of available 3D printed biomaterials...
Bulk-Fill Resins versus Conventional Resins: An Umbrella Review
Silva, Gonçalo; Marto, Carlos Miguel; Amaro, Inês; Coelho, Ana; Sousa, José Paulo; Ferreira, Manuel Marques; Francisco, InêsCurrently, composite resins have become the material of choice for the restoration of posterior teeth. Although bulk-fill resins represent a tempting alternative due to their lower complexity and faster use, some dentists are reluctant to use this material. The objective is to compare the performance of bulk-fill resins and conventional resins in direct restorations of posterior teeth based on the literature. T...
Relapse after Orthodontic-Surgical Treatment: A Retrospective Longitudinal Study
Matos, João; Travassos, Raquel; Caramelo, Francisco; Ribeiro, Madalena Prata; Marques, Filipa; Marto, Carlos Miguel; Paula, Anabela BaptistaLong-term stability is a crucial point in order to keep the patient’s aesthetic and functional balance. The aim of this study was to evaluate dental and skeletal relapse in patients who underwent orthodontic-surgical treatment. This retrospective study included 25 patients who corrected their dentofacial deformity through orthodontics and orthognathic surgery. The dental casts and lateral cephalograms were eval...
Bone Mineral Density through DEXA and CBCT: A Systematic Review with Meta-Analysis
Francisco, Inês; Nunes, Catarina; Pereira, Flávia; Travassos, Raquel; Ribeiro, Madalena Prata; Marques, Filipa; McEvoy, Mariana; Santos, MarianaDual-energy X-ray absorptiometry is used to determine bone density in several pathologies, namely osteoporosis and fracture risk in post-menopausal women. The aim of this study was to identify, appraise and synthesize all available evidence about the correlation between Dual Energy X-ray Absorptiometry (DEXA) and Cone Beam Computed Tomography (CBCT) techniques through a systematic review. A systematic literatur...
Microleakage Evaluation of Temporary Restorations Used in Endodontic Treatment-...
Paulo, Siri; Abrantes, Ana M.; Xavier, Mariana; Brito, Ana Filipa; Teixo, Ricardo; Coelho, Ana; Paula, Anabela; Carrilho, Eunice(1) Background: Coronal microleakage can lead to endodontic treatment failure. This study aimed to compare the sealing ability of different temporary restorative materials used during endodontic treatment. (2) Methods: Eighty sheep incisors were collected, uniformized in length, and access cavities were performed, except for in the negative control group, where the teeth were left intact. The teeth were divided...
Microleakage Study of a Bulk Fill over an Uncured Adhesive System
Pinto, Mariana Vaz; Pires, Salomé; Marto, Carlos Miguel; Amaro, Inês; Coelho, Ana; Sousa, José; Ferreira, Manuel Marques; Botelho, Maria FilomenaThis study aimed to evaluate and compare the microleakage of composite resin restorations under a total-etch adhesive system applied with two different techniques, with and without cure. Cavities were made on the buccal surface of twenty-six intact teeth and subsequently restored with bulk-fill flow composite resin (SDR®® flow+) and conventional resin (Spectra™ ST HV). Two experimental groups were created, one ...
Eyelid Reconstruction and Infraorbital Repair Using a Mustardé Flap Technique i...
Guerra Guimarães, Tarcísio; Menezes Cardoso, Karla; Pacheco, Magda; Olivério, Pedro; Faim, Susana; Marto, Carlos Miguel; Alexandre, NunoThis case report describes a 5-year-old dog with a defect in the right eyelid, absence of orbicularis musculature, and absence of cutaneous tissue in the infraorbital region, submitted to the Mustardé flap technique. A large rotational flap was performed, including a cartilage graft from the outer ear, to correct the defect in the lower eyelid and infraorbital region. Also, euryblepharon correction of the upper...
