A high level of unmet oral health needs is very common among elderly people. In a society that is getting older and that has been hit so hard by the coronavirus pandemic, the development of new strategies aimed at enhancing general and oral health status should be crucial in order to promote healthy aging. The aim of this systematic review is to assess the feasibility of Teledentistry in communities or in a domiciliary setting where elderly people live.

Association between hypertension, oral microbiome and salivary nitric oxide: A case-control study.

Background: Nitric oxide (NO) produced in the oral cavity is a powerful resource for the human body, especially when NO-syntethase production is not adequate. The role of oral microbiome in determining blood pressure levels has been linked to the active role of some bacterial species involved in the nitro-reducing process. In the present study we investigated the correlation between selected oral microbiome characteristics, nitric oxide (NO) concentration in saliva and their association with hypertension.

The aim of the study was to evaluate the impact of the coronavirus pandemic on the willingness, anxiety and concerns of Italian people on undergoing dental appointments. An anonymous survey was posted online on social media on 11 May 2020 and was completed by 1003 respondents in one week. Multiple correspondence analysis and multiple logistic regression were used to evaluate the association between socio-demographic characteristics, dental care access, contagion fear of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), trust in dentists regarding sanitization procedures and perception of the impact of the risk of contagion on dental care.

Impact of Elderly Masticatory Performance on Nutritional Status: An Observational Study.

Masticatory limitations on the dietary habits of edentulous subjects restrict their access to adequate nutrition, exposing them to a greater risk of protein energy malnutrition. The aim of this study is to verify the existence of an association between Masticatory Performance (MP) and nutritional changes in the elderly. 76 participants were enrolled.

Three-Dimensional Bone Augmentation and Immediate Implant Placement via Transcrestal Sinus Lift: 8-Year Clinical Outcomes.

When the edentulous posterior maxilla shows severe atrophy (Cawood and Howell Class V to VI), the traditional approach requires at least two surgical procedures. The first is a sinus lift (alone or with guided bone regeneration), and the second is to position implants. This article illustrates a technique that allows three-dimensional reconstruction of the sinus, placing an allogenous fresh bone block and simultaneous implant positioning using a computer-guided implant surgery.

Three-Dimensional Bone Augmentation and Immediate Implant Placement via Transcrestal Sinus Lift: Five-Year Clinical Outcomes.

This study proposed a surgical technique that solves three-dimensional conditions of extreme bone atrophy. A total of 278 surgeries with transcrestal sinus lift and fresh frozen allogenous bone blocks were performed. A total of 1,024 implants were placed.

Ceramic vs composite veneering of full arch implant-supported zirconium frameworks: assessing patient preference and satisfaction. A crossover double-blind randomised controlled trial.

Purpose: The objectives of this two-period, crossover, mono-centred, double-blind, randomised controlled trial (RCT) were to compare two different materials used for full arch implant-supported prosthetic restorations with regard to patient preference and impact on a patient's quality of life.

Materials And Methods: Edentulous patients requesting one full arch restoration in the mandible or maxilla supported by dental implants were included in this study. Patients were randomised to receive either a full arch zirconia framework hand-veneered with ceramic, or a full arch zirconia framework hand-veneered with composite material.

Purpose: The purpose of this study was to compare the clinical outcome of and determine the differences in periodonto-pathogenic microbiota around two types of implant collar surfaces: laser-microtextured (test) vs machined (control).

Materials And Methods: Seventeen patients (11 periodontally healthy, and 6 periodontally compromised) were selected to receive the two different implants, placed randomly, in two edentulous sites. Six months following the surgical placement of the dental implants, subgingival plaque samples were collected using paper points from the peri-implant sulcus and from the sulcus of an adjacent tooth.

Falls and collisions are the most commonly reported causes of dental injuries. These accidents involve principally the maxillary central incisors, causing uncomplicated crown fracture. Many materials and techniques can be used to restore injured anterior teeth.

Fiber-reinforced composite fixed partial denture to restore missing posterior teeth: a case report.

In patients refusing implant surgery for psychological reasons, when minimal tooth reduction is desired, a fiber-reinforced composite inlay fixed partial denture (IFPD) can be used to replace missing teeth. In comparison to other restorative systems this conservative approach carries a lower risk of pulp exposure and/or periodontal inflammation, maintaining the health of supporting tissues. The purpose of this case report is to describe the clinical procedure for fabricating an IFPD with a pre-impregnated glass fiber system and a hybrid composite.

The aim of this clinical report is to describe the management of a young patient, affected by ectodermal dysplasia, during a nine-year period. Dental treatment can vary depending on the severity of the disease (tooth size, morphology, and amount of available alveolar bone). New technologies, such as adhesive dentistry, and new materials, such as composite resin, represent current options in the management of the dental rehabilitation of patients affected by ectodermal dysplasia.

Stress distribution in fiber-reinforced composite inlay fixed partial dentures.

Statement Of Problem: Fiber-reinforced composite inlay fixed partial dentures (FRCIFPDs) may be a reliable prosthetic solution. Clinical procedures involved in their fabrication have been defined, but little is known about their mechanical behavior.

Restoration of anterior teeth with indirect composite partial coverage crowns: a clinical report.

When an esthetic restoration with minimal tooth reduction is desired, for example in patients with uncomplicated tooth fractures, composite partial coverage crowns may be a therapeutic option. The indirect composite restoration allows restoration of the original tooth anatomy, function, and esthetics to be reproduced while preserving tooth structure. The use of composite partial coverage crowns to restore fractured anterior teeth is described.

Clinical procedures for the immediate reattachment of a tooth fragment.

Uncomplicated crown fractures are frequent dental injuries, especially in young patients. It is beneficial to quickly restore the function and the aesthetics of the traumatized tooth. The immediate fragment reattachment is a therapeutic choice for uncomplicated anterior crown fractures, when the tooth is not luxated and the fragment is correctly stored.
