In the network of periodontitis immunomediators
Viana da Costa, Alexandra; Mendes-Frias, Ana; Gonçalves, Maria; Salazar, Filomena; Silvestre, Ricardo; Relvas, MartaBackground: Severe periodontitis is considered the sixth most prevalent disease worldwide [1]. It is a chronic inflammatory condition affecting the tooth-supporting structures due to genetic, environmental, and microbial factors [2]. The host immune response partially contributes to the magnitude of the inflammatory process. Furthermore, this process involves a diversity of immunomediators that initiate and sus...
Osseodensification vs. Conventional Osteotomy: A case series with cone beam com...
Costa, José Adriano; Mendes, José Manuel; Salazar, Filomena; Pacheco, José Júlio; Rompante, Paulo; Moreira, Joaquim Ferreira; Mesquita, José DiogoOsseodensification is a non-extraction technique using specially designed drills to increase bone density while extending an osteotomy, allowing bone to be preserved and condensed by compacting autograft during osteotomy preparation, increasing bone density around implants, and improving mechanical stability. The objective of this study is to compare conventional osteotomy and osseodensification protocols in im...
In vitro study of preload loss in different implant abutment connection designs
Vinhas, Ana Sofia; Aroso, Carlos; Salazar, Filomena; Relvas, Marta; Braga, A. C.; Ríos-Carrasco, Blanca; Gil, Javier; Rios-Santos, José VicenteThe stability and integrity of the abutment-implant connection, by means of a screw, is fallible from the moment the prosthetic elements are joined and is dependent on the applied preload, wear of the components and function. One of the main causes of screw loosening is the loss of preload. The loosening of the screw-abutment can cause complications such as screw fracture, marginal gap, peri-implantitis, bacter...
Study of prevalence, severity and risk factors of periodontal disease in a Port...
Relvas, Marta; López-Jarana, Paula; Monteiro, Luis; Pacheco, José Júlio; Braga, A. C.; Salazar, FilomenaPeriodontal disease is a common worldwide oral inflammation/infection affecting tissues that surround and support teeth. This study aims to evaluate the prevalence, extent and severity of periodontal diseases and its risk factors, according to the most recent periodontal classification, in an adult population of Northern Portugal. This observational study collected data from clinical records of patients who att...
Clinical improvement following therapy for periodontitis: Association with a de...
Reis, Cátia; Viana Da Costa, Alexandra; Guimarães, João Tiago; Tuna, Diana; Braga, Ana Cristina; Pacheco, José Júlio; Arosa, Fernando A.Although a number of inflammatory cytokines have been shown to be associated with periodontal pathogenesis, it is important to investigate further whether these biomarkers are associated with the degree of success in nonsurgical treatment of chronic periodontitis. The aim of the present study was to quantify the total levels of interleukin (IL)‑1α, ‑1β, ‑6, ‑10 and tumour necrosis factor (TNF)‑α in gingival cre...
Full-mouth periodontal examination prior to and after nonsurgical treatment in ...
Reis, Cátia; Manzanares-Céspedes, Maria Cristina; Pacheco, José Júlio; Salazar, Filomena; Cardoso, Elsa M.Chronic periodontitis is a pathological condition characterized by loss of the supporting tissues of the teeth. The aim of this study was to evaluate the distribution of disease sites in different areas of mouth, prior to and following short-term nonsurgical treatment, as well as the successful of treatment. Periodontal parameters, including Probing Pocket Depth (PPD), Clinical Attachment Level (CAL) and Bleedi...
Agenesia dentária: a importância da amamentação materna
Couraceiro, Luís; Santos, António; Salazar, Filomena; Ferreira da Vinha, Ana; Almeida-Dias, António; Manzanares, CristinaOs dentes são estruturas importantes e indispensáveis para a função mastigatória. A ausência de um ou mais dentes, pode ser um problema sério, designado por agenesia dentária. Os dentes, que começam a surgir ainda na fase de lactência, devem estar prontos para serem trocados pelos dentes permanentes entre os seis e os nove anos de idade. Na fase adulta, uma pessoa deverá apresentar na cavidade oral 32 dentes. N...
