Cervical Tuberculosis Mimicking Cervical Cancer in a Postmenopausal Woman

Publisher Copyright: © 2025 by the authors.; Cervical tuberculosis is a rare form of genital tuberculosis. A case of a 73-year-old woman who presented with cervical wall thickening on magnetic resonance imaging, suggesting an invasive malignant neoplasm, is documented. Cervical cone excision was performed for histopathological study. Microscopy showed epithelioid granulomas, without appreciable caseous necrosis...

Utilização de nitrito de sódio como meio de suicídio. Nova tendência?

O nitrito de sódio é um composto inorgânico utilizado como preservante na indústria alimentar, na agricultura, como anticorrosivo e como antídoto em caso de intoxicações por cianetos. O consumo deste composto pode ser potencialmente letal, visto este interferir com a capacidade de os glóbulos vermelhos transportarem o oxigénio, fundamental à vida. O ferro da hemoglobina, na presença deste composto, passa à form...

Three-Dimensional Pulp Volume Analysis in Lip and Palate Cleft Population

Aim: Cleft lip and palate (CLP) patients have a greater predisposition to tooth malformation, which could affect pulp volume. The aim of this study is to evaluate the dental pulp volume of central incisors in 3D images between individuals with and without CLP. Materials and Methods: This retrospective case-control study is single-centered and was recruited between January 2016 and October 2022. Ninety-four pati...

Three-Dimensional Impression of Biomaterials for Alveolar Graft: Scoping Review

Craniofacial bone defects are one of the biggest clinical challenges in regenerative medicine, with secondary autologous bone grafting being the gold-standard technique. The development of new three-dimensional matrices intends to overcome the disadvantages of the gold-standard method. The aim of this paper is to put forth an in-depth review regarding the clinical efficiency of available 3D printed biomaterials...

Relapse after Orthodontic-Surgical Treatment: A Retrospective Longitudinal Study

Long-term stability is a crucial point in order to keep the patient’s aesthetic and functional balance. The aim of this study was to evaluate dental and skeletal relapse in patients who underwent orthodontic-surgical treatment. This retrospective study included 25 patients who corrected their dentofacial deformity through orthodontics and orthognathic surgery. The dental casts and lateral cephalograms were eval...

Bone Mineral Density through DEXA and CBCT: A Systematic Review with Meta-Analysis

Dual-energy X-ray absorptiometry is used to determine bone density in several pathologies, namely osteoporosis and fracture risk in post-menopausal women. The aim of this study was to identify, appraise and synthesize all available evidence about the correlation between Dual Energy X-ray Absorptiometry (DEXA) and Cone Beam Computed Tomography (CBCT) techniques through a systematic review. A systematic literatur...

The COVID-19 Impact on Oral Healthcare Demand and Performance: The Experience o...

Introduction: The SARS-CoV-2 pandemic has reshaped the global landscape as we know it and had a tremendous effect on healthcare systems around the world. However, its impact on oral healthcare is still to be fully assessed. The aim of this study was to understand if and how COVID-19 affected the demand and performance of oral healthcare, taking the Clinical and Academic Centre of Coimbra as an example, more spe...

Realistic Facial Three-Dimensional Reconstruction from CT Images and 2D Photogr...

Orthognathic surgery is a procedure used to correct intermaxillary discrepancies, thus promoting significant improvements in chewing and breathing. During the surgical planning stage, orthodontists often use two-dimensional imaging techniques. The assessment is based on CBCT images and dental cast models to overcome these limitations; however, the evaluation of soft tissues remains complex. The aim of the prese...

The Biological Effects of 3D Resins Used in Orthodontics: A Systematic Review

Three-dimensional (3D) resin medical-dental devices have been increasingly used in recent years after the emergence of digital technologies. In Orthodontics, therapies with aligners have gained popularity, mainly due to the aggressive promotion policies developed by the industry. However, their systemic effects are largely unknown, with few studies evaluating the systemic toxicity of these materials. The releas...
