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...
Realistic Facial Three-Dimensional Reconstruction from CT Images and 2D Photogr...
Monteiro, Miguel; Vale, Francisco; Ferreira, Nuno C.; Marques, Filipa; Ribeiro, Madalena Prata; Santos, Mariana; Oliveira, Catarina; McEvoy, MarianaOrthognathic surgery is a procedure used to correct intermaxillary discrepancies, thus promoting significant improvements in chewing and breathing. During the surgical planning stage, orthodontists often use two-dimensional imaging techniques. The assessment is based on CBCT images and dental cast models to overcome these limitations; however, the evaluation of soft tissues remains complex. The aim of the prese...
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 ...
The Biological Effects of 3D Resins Used in Orthodontics: A Systematic Review
Francisco, Inês; Paula, Anabela Baptista; Ribeiro, Madalena; Marques, Filipa; Travassos, Raquel; Nunes, Catarina; Pereira, Flávia; Marto, Carlos MiguelThree-dimensional (3D) resin medical-dental devices have been increasingly used in recent years after the emergence of digital technologies. In Orthodontics, therapies with aligners have gained popularity, mainly due to the aggressive promotion policies developed by the industry. However, their systemic effects are largely unknown, with few studies evaluating the systemic toxicity of these materials. The releas...
What Is the Most Effective Technique for Bonding Brackets on Ceramic-A Systemat...
Francisco, Inês; Travassos, Raquel; Nunes, Catarina; Ribeiro, Madalena; Marques, Filipa; Pereira, Flávia; Marto, Carlos Miguel; Carrilho, EuniceBackground: There has been an increase in demand for orthodontic treatment within the adult population, who likely receive restorative treatments using ceramic structures. The current state of the art regarding the most effective method to achieve an appropriate bond strength of brackets on ceramic surfaces isn't consensual. This systematic review aims to compare the available surface treatments to ceramics and...
Application of Three-Dimensional Digital Technology in Orthodontics: The State ...
Francisco, Inês; Ribeiro, Madalena Prata; Marques, Filipa; Travassos, Raquel; Nunes, Catarina; Pereira, Flávia; Caramelo, FranciscoThree-dimensional technologies are one of the most recent and relevant advancements in the field of Dentistry. These systems, including intraoral scans, 3D imaging exams (CAT scan, CBCT and MRI), CAD/CAM 3D printing devices and 3D computer software, have enabled clinicians to greatly improve patient care along with reducing treatment planning time. The present descriptive study aims to explore possible applicat...
