Dental Implants and Orthodontic Mini-Screws in a Patient with Undiagnosed Von Willebrand's Disease: A Case Report.

Dental implants are commonly employed to address edentulism, while orthodontic treatments often incorporate mini-screws to enhance tooth movement and provide stable anchorage. Both procedures are integral to modern dental practice and frequently interact in comprehensive care scenarios. While oral health professionals routinely assess patients' medical histories before procedures, undiagnosed coagulopathies, such as Von Willebrand Disease (VWD), can present significant challenges when invasive procedures are carried out, such as the insertion of implants or mini-implants.

Premature loss of primary molars in children: space recovery through molar distalisation. A literature review.

Aim: The integrity of primary dentition is essential in the development of the jaws and permanent occlusion. The consequences of a premature loss of primary molars are: space loss, crowding, risk of impaction of the permanent teeth, ectopic eruption, anomalous inclination of the teeth adjacent to the loss molar, reduction of arch length. The mesial displacement of the posterior permanent teeth during eruption can cause a loss of space, which can be regained with orthodontic appliances.

Correlation between facial growth patterns and cortical bone thickness assessed with cone-beam computed tomography in young adult untreated patients.

Background: The vertical facial growth pattern is one of the most important issue in the orthodontic diagnosis and treatment. Previous studies investigated the association between interdental bone thickness and facial divergence using mainly bidimensional analysis. When two-dimensional dental radiographic views are not sufficient for diagnosis and measurements, cone-beam computed tomography (CBCT) images should be used to assess the alveolar bone structure three-dimensionally and with high accuracy and reliability.

Correlation between Malocclusion and Allergic Rhinitis in Pediatric Patients: A Systematic Review.

Background: Oral breathing, nasal obstruction and airway space reduction are usually reported as associated to allergic rhinitis. They have been linked to altered facial patterns and dento-skeletal changes. However, no firm correlation based on the evidence has been established.

A Scoping Review of Respirator Literature and a Survey among Dental Professionals.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus was discovered in China in late 2019 and subsequently triggered a global pandemic. Dentists, like many other health professionals, are at an increased risk of contracting the virus as they work in close proximity to patients, especially when performing aerosol-generating procedures. Thus, in order for dentists to protect themselves and their patients, it is recommended that practitioners wear filtering facepiece 2 (FFP2) respirators.
