Collagenated Porcine Heterologous Bone Grafts: Histomorphometric Evaluation of ...

Falacho, Rui I.; Palma, Paulo J.; Marques, Joana A.; Figueiredo, Maria H.; Caramelo, Francisco; Dias, Isabel; Viegas, Carlos; Guerra, Fernando

Collagenated porcine-derived bone graft materials exhibit osteoconductive properties and the development of different formulations intends to enhance bone regeneration. This study aims to evaluate bone healing in a rabbit cancellous bone defect in response to grafting with different physicochemical forms of heterologous porcine bone. Twenty-six adult male New Zealand White rabbits received two critical size fem...


Subcutaneous Implantation Assessment of New Calcium-Silicate Based Sealer for W...

Santos, João Miguel; Coelho, Carolina M.; Sequeira, Diana B.; Marques, Joana A.; Pereira, Joana F.; Sousa, Vítor; Palma, Paulo J.; Santos, Ana C. G.

Calcium silicate-based sealers were recently introduced as a new class of endodontic sealers, with potential further benefits due to their bioactivity. The aim of this study was to evaluate the biocompatibility of two new hydraulic calcium silicate-based sealers, TotalFill BC Sealer (FKG, La Chaux-des-Fonds, Switzerland) and TotalFill BC Sealer HiFlow (FKG, La Chaux-des-Fonds, Switzerland) through subcutaneous ...


Tooth Discoloration after Regenerative Endodontic Procedures with Calcium Silic...

Palma, Paulo J.; Marques, Joana A.; Santos, Joana; Falacho, Rui I.; Sequeira, Diana B.; Diogo, Patrícia; Caramelo, Francisco; Ramos, João C.

The aim of the present ex vivo study was to assess and compare coronal discoloration induced by four endodontic biomaterials used in regenerative endodontic procedures (REPs). Root resection was executed horizontally, 2 mm apical to the cementoenamel junction, in all fifty-four teeth. After accessing the pulp chamber, specimens were randomly divided in groups and filled with either saline solution or blood, fol...


Evaluation of Root-End Preparation with Two Different Endodontic Microsurgery U...

Palma, Paulo J.; Marques, Joana A.; Casau, Margarida; Santos, André; Caramelo, Francisco; Falacho, Rui I.; Santos, João Miguel

The aim of this study is to compare root-end preparation performed with two different ultrasonic tips-CVDentus and NSK-and respective time requirements. After root-end resection, 32 teeth were randomly divided in two groups, according to the ultrasonic tip used for root-end preparation. Preparation time was recorded. Photomicrographs were taken to assess the following parameters: root surface microcracking, mar...


Six-Month Color Stability Assessment of Two Calcium Silicate-Based Cements Used...

Palma, Paulo J.; Marques, Joana A.; Falacho, Rui I.; Correia, Eder; Vinagre, Alexandra; Santos, João Miguel; Ramos, João C.

Aim: The purpose of the present study is to assess the color stability of two calcium silicate-based cements (CSCs) used in regenerative endodontic procedures (REPs). Methods: A total of 40 acrylic single-rooted transparent teeth, with immature apex, were used. Root canals were filled up to 3 mm below the level of the cementoenamel junction, with either saline solution (Mineral Trioxide Aggregate (MTA)/saline a...


Does Delayed Restoration Improve Shear Bond Strength of Different Restorative P...

Palma, Paulo J.; Marques, Joana A.; Falacho, Rui I.; Vinagre, Alexandra; Santos, João Miguel; Ramos, João C.

The purpose of the present study was to assess the proper time to perform a restoration (immediately or delayed) after placement of two calcium silicate-based cements (CSCs) and to test the performance of two different restorative protocols regarding shear bond strength (SBS). Seventy-five acrylic blocks were randomly divided into five groups (n = 15). Specimens were filled with either ProRoot MTA (Dentsply Tul...
