Randomized clinical study of injectable dextrin-based hydrogel as a carrier of ...
Machado, Alexandra; Pereira, Isabel; Costa, Filomena; Brandão, Ana; Pereira, José Eduardo; Maurício, Ana Colette; Santos, José Domingos; Amaro, InêsObjectives This study aimed to improve the performance and mode of administration of a glass-reinforced hydroxyapatite synthetic bone substitute, Bonelike by Biosckin® (BL®), by association with a dextrin-based hydrogel, DEXGEL, to achieve an injectable and moldable device named DEXGEL Bone. Methods Twelve participants requiring pre-molar tooth extraction and implant placement were enrolled in this study. BL® g...
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...
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 ...

Isolation and Identification of Cytotoxic Compounds Present in Biomaterial Life®
Ferreira, Maria Beatriz; Pereira, Nelson A. M.; Marto, Carlos Miguel; Cardoso, Miguel; Amaro, Inês; Coelho, Ana; Saraiva, José; Spagnuolo, GianricoDirect pulp capping consists of a procedure in which a material is directly placed over the exposed pulp to maintain dental vitality. Although still widely used in clinical practice, previous in vitro studies found that the biomaterial Life® presented high cytotoxicity, leading to cell death. This study aimed to identify the Life® constituents responsible for its cytotoxic effects on odontoblast-like cells (MDP...

Mechanical and Tribological Characterization of a Bioactive Composite Resin
Carneiro, Elsa Reis; Coelho, Ana Sofia; Amaro, Inês; Paula, Anabela Baptista; Marto, Carlos Miguel; Saraiva, José; Ferreira, Manuel MarquesDespite developments and advances in dental materials which allow for greater restorative performance, there are still challenges and questions regarding the formulation of new compositions and chemical reactions of materials used in restorative dentistry. The aim of this study was to assess and compare the mechanical and tribological characteristics of a bioactive resin, a composite resin, and a glass ionomer....
Minimally Invasive Dentistry for Pre-Eruptive Enamel Lesions—A Case Series
Manaia, Mariana; Rocha, Larissa; Saraiva, José; Coelho, Ana; Amaro, Inês; Marto, Carlos Miguel; Vale, Francisco; Ferreira, Manuel MarquesPre-eruptive enamel lesions occur during tooth formation and include fluorosis, traumatic hypomineralization, and molar incisor hypomineralization. Minimally invasive treatment approaches, such as microabrasion, should be considered for these cases. This article presents a case series of three patients with pre-eruptive enamel defects in esthetically compromised tooth regions which were treated with the microab...
Effect of Cavity Disinfectants on Adhesion to Primary Teeth-A Systematic Review
Coelho, Ana; Amaro, Inês; Paula, Anabela; Saraiva, José; Ferreira, Manuel Marques; Marto, Carlos Miguel; Carrilho, Eunice; Apolónio, AnaSome authors have been proposing the use of cavity disinfectants in order to reduce, or even eliminate, the effect of the microorganisms present in a dental cavity before a restoration is placed. The aim of this study was to evaluate the effect of different cavity disinfectants on bond strength and clinical success of composite and glass ionomer restorations on primary teeth. The research was conducted using Co...
Direct Restorations for Anterior Esthetic Rehabilitation and Smile Symmetry Rec...
Amaro, Inês; Saraiva, José; Gomes, Ana Catarina; Araújo, Ana; Marto, Carlos Miguel; Coelho, Ana; Ferreira, Manuel Marques; Paula, AnabelaEsthetics is an increasing concern for patients, particularly in anterior teeth. The current approaches to manage the esthetic demands include options such as prosthodontic rehabilitation, orthodontic treatment, and direct restorations. Direct restorative procedures for anterior teeth have become a reliable alternative, since current composite materials can mimic teeth’s esthetics and function perfectly. This a...
