Non-Surgical Periodontal Treatment Impact on Subgingival Microbiome and Intra-O...
Izidoro, Catarina; Botelho, João; Machado, Vanessa; Reis, Ana Mafalda; Proença, Luís; Barroso, Helena; Alves, Ricardo; Mendes, José JoãoThe purpose of this study was to characterize and compare subgingival microbiome before and after periodontal treatment to learn if any changes of the subgingival microbiome were reflected in intra-oral halitosis. We tested the hypothesis that intra-oral halitosis (Volatile sulfur compounds levels) correlates with corresponding subgingival bacterial levels before and after periodontal treatment. Twenty patients...
Addressing ageism : be active in aging: study protocol
Fernandes, Júlio Belo; Ramos, Catarina; Domingos, Josefa; Castro, Cidália; Simões, Aida; Bernardes, Catarina; Fonseca, Jorge; Proença, LuísAgeism refers to stereotyping (how we think), prejudice (how we feel), and discrimination (how we act) against people based on their age. It is a serious public health issue that can negatively impact older people’s health and quality of life. The present protocol has several goals: (1) adapt the Ambivalent Ageism Scale for the general Portuguese population and healthcare professionals; (2) assess the factorial...
An umbrella review of the evidence of sex determination procedures in forensic ...
Neves, João Albernaz; Antunes-Ferreira, Nathalie; Machado, Vanessa; Botelho, João; Proença, Luís; Quintas, Alexandre; Delgado, Ana SintraSex determination in forensic dentistry is a major step towards postmortem profiling. The most widely recognized method is DNA, yet its application in the dental field of forensic sciences is still impractical. Depending on the conditions of the remains, teeth are often the only surviving organ. Some systematic reviews (SRs) have been recently produced; hence this umbrella review critically assesses their level...
An umbrella review of the evidence linking oral health and systemic noncommunic...
Botelho, João; Mascarenhas, Paulo; Viana, João; Proença, Luís; Orlandi, Marco; Leira, Yago; Chambrone, Leandro; Mendes, José João; Machado, VanessaOral diseases are highly prevalent worldwide. Recent studies have been supporting a potential bidirectional association of oral diseases with systemic noncommunicable diseases (NCDs). Available evidence supports that people with NCDs have a greater prevalence of oral diseases particularly those with limited ability of oral self-care. Regarding the reverse relationship, the lines of evidence pointing out NCDs as...
Cross-cultural adaptation and validation of the Portuguese version of the psych...
Fidalgo, João; Botelho, João; Proença, Luís; Mendes, José João; Machado, Vanessa; Delgado, Ana SintraThe aim of this study was to cross-culturally adapt and validate the psychosocial impact of dental esthetics questionnaire (PIDAQ) to the Portuguese language. The PIDAQ was culturally translated and adapted according to international guidelines. In this cross-sectional study, we enrolled 501 subjects in a population-based epidemiological survey conducted at the Egas Moniz Dental Clinic (Almada, Portugal) in Jun...

Machado, Vanessa; Mendonça, André; Proença, Luís; Mendes, José João; Botelho, João; McNeill, Daniel W.; Delgado, Ana SintraBackground: To adapt and validate cross-culturally the Oral Health Values (OHVS) questionnaire to Portuguese language. Methods: The OHVS questionnaire was culturally translated and adapted according to international guidelines. We enrolled 280 patients in a population-based epidemiological survey conducted at the Egas Moniz Dental Clinic (Almada, Portugal). The participants answered the Portuguese version of th...
Industrial noise : a new stimulus for dental pulp aging? Qualitative and quanti...
Cavacas, Maria Alzira; Doroteia, Carolina; Leonardo, Ana Margarida; Proença, Luís; Tavares, VítorMorphological changes induced by industrial noise have been experimentally observed in several organs. This study aims to characterize the effect of industrial noise on the pulp cell density of Wistar rats from a histological point of view, through qualitative and quantitative analysis. The histologic sections were observed over the optical microscope and photographed using 10x and 40x magnifications and analyz...
Increasing acid concentration, time and using a two-part silane potentiates bon...
Almiro, Matilde; Marinho, Beatriz; Delgado, António H. S.; Rua, João; Monteiro, Paulo; Santos, Inês Caetano; Proença, Luís; Mendes, José JoãoThere is still a lack of consensus concerning the recommended etching concentration, application time and type of silane when bonding lithium disilicate-reinforced glass ceramics manufactured by CAD/CAM. The purpose of this study was thus to conduct an in vitro study which investigates the influence of hydrofluoric acid (HF) concentration, etching time and silane type on the microtensile bond strength (μTBS) of...
Geographical distribution of periodontitis risk and prevalence in Portugal usin...
Antunes, Ana; Botelho, João; Mendes, José João; Delgado, Ana Sintra; Machado, Vanessa; Proença, LuísWe aimed to estimate the geographical distribution of periodontitis prevalence and risk based on sociodemographic and economic data. This study used sociodemographic, economic, and health services data obtained from a regional survey and governmental open data sources. Information was gathered for all 308 Portuguese municipalities and compiled in a large set of 52 variables. We employed principal component anal...
Association between IL-1A and IL-1B gene polymorphisms with peri-implantitis in...
Cardoso, José Maria; Ribeiro, Ana Clara; Palos, Constança; Proença, Luís; Noronha, Susana; Alves, Ricardo CastroBackground: Scientific evidence indicates that biological complications in dental implants tend to be concentrated in a subset of individuals, which seems to imply that the host response may play a determining role in implant success. Over the last few decades, several polymorphisms have been studied. Polymorphisms in the interleukin (IL) 1 gene cluster have been associated with periodontitis. There are some si...
