Effect of Propolis on Root Dentine Microhardness When Used as an Intracanal Med...
Naeem, Meshal Muhammad; Sarwar, Huma; Nisar, Aliza; Ahmed, Shahbaz; Shabbir, Juzer; Khurshid, Zohaib; Palma, Paulo J.Application of intracanal medicaments may affect the physical properties of root dentine. Calcium hydroxide (CH), a gold standard intracanal medicament, has proven to decrease root dentine microhardness. A natural extract, propolis, has been shown to be superior to CH in eradicating endodontic microbes, but its effect on the microhardness of root dentine is still not known. This investigation aims to evaluate t...

Meschi, Nastaran; Palma, Paulo J.; Cabanillas-Balsera, DanielRevitalization procedures primarily aim to eliminate clinical symptoms and heal periapical lesions.
Assessment of the Prevalence of Radix Entomolaris and Distolingual Canal in Man...
Hatipoğlu, Fatma Pertek; Mağat, Güldane; Hatipoğlu, Ömer; Al-Khatib, Hanan; Elatrash, Anas S; Abidin, Imran Zainal; Kulczyk, TomaszThe aim of this study was two-folded: i) to assess the prevalence of Distolingual Canal (DLC) and Radix Entomolaris (RE) in Mandibular First Molars (M1Ms), using Cone Beam Computed Tomography (CBCT) images and ii) to assess the impact of sociodemographic factors on the prevalence of these conditions worldwide.

Delayed Cutaneous Adverse Reaction of the AstraZeneca COVID-19 Vaccine in a Bre...
Diogo, Patrícia; Correia, Gil; Martins, João B.; Soares, Rui; Palma, Paulo J.; Santos, João Miguel; Gonçalves, TeresaThe ChAdOx1 nCoV-19 vector vaccine (Vaxzevria, AstraZeneca, Cambridge, UK) was developed at Oxford University and is considered safe for the administration in lactating mothers. Nevertheless, as a novel vaccine, there are gaps in the knowledge regarding possible adverse events in breastfeeding infants of vaccinated mothers. This case report provides first-time data on a possible delayed, cutaneous, adverse reac...
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, FernandoCollagenated 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...
Influence of Cavity Geometry on the Fracture Strength of Dental Restorations: F...
Neto, Maria A.; Roseiro, Luís; Messias, Ana; Falacho, Rui I.; Palma, Paulo J.; Amaro, Ana M.The main purpose of this work was to analyze the stress distribution in premolars restored with indirect IPS Empress® CAD onlays or inlays. The three-dimensional geometry of a human first premolar was created using modeling software. The tooth fixation system was simu-lated through box geometry, comprising a cortical bone layer with 2 mm of thickness over a layer of trabecular bone with 15 mm of thickness. The ...
Management of Pulp Canal Obliteration-Systematic Review of Case Reports
Vinagre, Alexandra; Castanheira, Catarina; Messias, Ana; Palma, Paulo J.; Ramos, JoãoBackground and Objectives: This systematic review aimed to assess the literature focusing on the clinical management of traumatized teeth with Pulp Canal Obliteration (PCO) and propose an updated clinical decision-making algorithm. The present review follows the PRISMA guidelines and was registered on PROSPERO database (CRD42020200656). Materials and Methods: An electronic search strategy was performed in Pubme...
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...
