Accuracy assessment of prototypes using multi-slice and cone beam computed tomography
The objective of this study was to assess and quantify the dimensional error of prototypes produced using multi-slice and cone-beam computed tomography(MSCT and CBCT). Titanium screws were inserted into a dry skull at diferente points of the midface. The skull was scanned using MSCT (LightSpeed161) with pixel size 0.3 mm and CBCT (i-CA...
Towards designing for equity: Active citzen participation in eHealth
Purpose – Reducing inequity in accessing healthcare among rural and remote populations remains a problem. Internationally, eHealth is now touted as a potential solution, with a range of diverse approaches and impacts. Yet, the equity gains of implementing eHealth are often not realized due to a lack of effective strategies for citizen ...
The Brazilian dental diagnostic day
Diagnostic cases in oral medicine. Dental diagnostics is always a challenge and sometimes a true dilema.
Artifacts infuence on proximal caries diagnosis with CBCT images
The purpose of this work was to analyze the influence of artifacts generated by almalgam restorations on proximal caries diagnosis. Fourteen healthy human premolars were poditioned in pairs on blocks made with heavy silicone keeping their proximal contact points. Class II amalgam restorations in each proximal surface were performed followed by...
Radiographic and histological density of peri-implant bone in animal study
Radiographic density analysis of jaw bone by adding an aluminum step wedge has shown high precision, accuracy and diagnostic specificity in previous studies. Objectives: To determine aluminum equivalent density(AED) values of peri-implant bone at implant neck, threads and apical regions, identify bone density changes after healing and check if AED...
Editorial : O cenário atual dos periódicos brasileiros de odontologia
Dentro do contexto da evolução da pós-graduação brasileira, um dos aspectos que merece uma análise reflexiva por sua importância na divulgação do conhecimento produzido é o atual papel dos periódicos científicos editados no Brasil. A odontologia apresenta atualmente o segundo maior índice de crescimento da produção bibliográfica dos programas de ...
Editorial: Call for action in Brazil: dealing with misconduct in research and scientific publication
Cases of misconduct in research and scientific publications have populated the headings of both national and international news lately. There are no borders regarding incidence of misconduct in developed, developing or underdeveloped parts of the world, and all areas of knowledge are affected. This universal problem has become more evident and...
Editorial: Integridade na pesquisa e ética na publicação
As exigências de produção intelectual com base nas publicações científicas constituem mecanismos de pressão sobre pesquisadores, docentes e discentes de programas de pós-graduação, uma vez que os indicadores de qualidade acadêmica estão atualmente atrelados à produção bibliográfica tanto no Brasil quanto no exterior. Nesse contexto, tornam-se cada vez mai...
A three-dimensional finite element analysis of mandibular overdenture supported by cylindrical and conical implants
This 3D finite element study assessed the stress distribution in mandibular overdenture supported by the 3i Locator system attached to two cylindrical or conical implants placed at the canine region. A 100 N vertical load was applied over the right first molar of the two overdenture models. The von Mises stresses were concentrated ...
Treatment of squamous cell carcinoma of lower lip with carbon dioxide (CO2) laser
Squamous cell carcinoma (SCC) represents 95% of oral cavity cancers, including tongue and lips. In most cases, if this lesion is diagnosed in the initial stages, the treatment of choice is surgery under general anesthesia. This clinical study examined the efficacy of CO2 laser treatment of SCC of the lower lip in an ambulatory...
