3D printing vs traditional workflow for the fabrication of mandibular implant overdentures: study protocol for a mixed-methods cross-over RCT.

Background: Complete tooth loss is a significant global oral health issue, particularly impacting older individuals with lower socioeconomic status. Computer-assisted technologies enhance oral healthcare access by the elderly. Despite promising in vitro reports on digital denture materials, evidence from randomized clinical trials (RCTs) is lacking to verify their performance.

Geroscience: Aging and Oral Health Research.

Research in aging has significantly advanced; scientists are now able to identify interventions that slow the biologic aging processes (i.e., the "hallmarks of aging"), thus delaying the onset and progression of multiple diseases, including oral conditions.

Patient-Reported Outcomes and Clinical Performance of CAD/CAM Removable Dentures: A Scoping Review.

Purpose: To review the literature on CAD/CAM removable complete and partial dentures regarding patient- and clinician-reported outcomes.

Materials And Methods: We performed an electronic search of the Cochrane Central Register of controlled trials (CENTRAL), MEDLINE (Ovid), EMBASE, Scopus, and Web of Science databases (last update: March 2023). All clinical trials or observational studies investigating CAD/ CAM removable dentures (conventional or implant-retained) were included.

A Cluster Analysis of Oral and Cognitive Health Indicators in the CLSA: An Exploratory Study on Cholinergic Activity as the Link.

Introduction: Poor oral health has been suggested as a risk factor for cognitive decline. Yet, biologically plausible mechanisms explaining this relationship remain unknown.

Objectives: We aimed (1) to identify oral and cognitive health clustering patterns among middle-aged to elderly Canadians and (2) to investigate the extent to which these patterns could be explained by bone mineral density (BMD), a proxy measure of the cholinergic neurons' activity.

Can patients detect peri‑implant mucosal inflammation? Results from a multicentre randomized trial.

Purpose: The objective of this study was to compare patient-reported outcomes (PROs) of peri‑implant soft tissue inflammation and aesthetics around single-tooth implants in the anterior maxillary region with three different implant-abutment interface designs.

Methods: Participants were randomized to one of three different types of implant-abutment interface designs [Conical (CI), flat-to-flat (FI), and Platform Switched (PS)]. Implants and provisional crowns with prefabricated titanium abutments were placed 5 months following extraction and/or ridge augmentation.

The impact of implant-retained overdentures on type-2 diabetic and non-diabetic edentulous patients: Satisfaction and quality of life in a prospective cohort study.

Objectives: To evaluate the benefits of implant therapy for patients with diabetes, we compared (i) healthy, (ii) well controlled T2DM and (iii) poorly controlled T2DM patients, in terms of oral health-related quality of life (OHRQoL) and satisfaction with mandibular 2-implant overdentures over 12 months following restoration.

Materials And Methods: This single-center, prospective, cohort study recruited 165 edentulous adults (HbA1c<12%) to receive two endosseous implants in the anterior mandible to support mandibular overdentures. Participants were enrolled as having T2DM or not, with T2DM participants divided according to HbA1c into well-controlled (<8.

Validity of Chatbot Use for Mental Health Assessment: Experimental Study.

Background: Mental disorders in adolescence and young adulthood are major public health concerns. Digital tools such as text-based conversational agents (ie, chatbots) are a promising technology for facilitating mental health assessment. However, the human-like interaction style of chatbots may induce potential biases, such as socially desirable responding (SDR), and may require further effort to complete assessments.

Single-Implant Overdentures Retained by a Novel Attachment: A Mixed Methods Crossover Randomized Clinical Trial.

Introduction: Single-implant mandibular overdentures (SIMOs) are one of the least invasive implant treatments for edentulism. The new Novaloc attachment system can improve the clinical performance of implant-retained overdentures but has not been tested for SIMOs.

Objectives: To compare Novaloc and a gold standard system (Locator) for SIMOs in an edentate elderly population in terms of patient-reported outcomes and device- and treatment-related complications.

Sociodemographic Changes and Oral Health Inequities: Dental Workforce Considerations.

Background: By midcentury, the US population will be remarkably more racially and ethnically diverse, with a dramatic increase in the proportion of older adults. This report addresses ongoing oral health disparities and inequitable access to care related to these changes, with emphasis on implications for the workforce, taking note of effects of the COVID-19 pandemic.

Relevant Considerations: Considering that social determinants shape health behaviors, reflection on the most effective type of dental workforce should take into account population characteristics and the relationship of oral health with overall health and general well-being.

Oral health in America 2021: Making a case for curricular change.

Background: The NIH Oral Health in America: Advances and Challenges report is the most recent evidence-based review of the status of oral health in North America since Oral Health in America: A Report of the Surgeon General, which was published in 2000. This article aims to synthesize and discuss information from the report pertinent to improving dental education to positively impact oral health. Calls for action and suggestions for implementation are presented.

Woman authorship in pre-print versus peer-reviewed oral health-related publications: A two-year observational study.

Objectives: Women in oral health science face similar societal issues and challenges as those in other STEMM careers, and gender disparities continue to exist as evidenced by fewer women represented as first and last authors in scientific publications. Pre-prints may serve as a conduit to immediately disseminating one's work, bypassing the arduous peer review process and its associated inherent biases. Therefore, the purpose of this study was to 1] compare the gender of first and last authors in pre-print versus peer reviewed publications, 2] examine the composition of first and last author pairs as stratified by publication type, and 3] examine the correlation between woman authorship and institutional geographic location and publication metrics stratified by publication type.

Patients' E-Readiness to use E-Health technologies for oral health.

Introduction: Scientific evidence highlights the importance of E-Readiness in the adoption and implementation of E-Oral Health technologies. However, to our knowledge, there is no study investigating the perspective of patients in this regard. Therefore, the objective of this study was to explore patients' E-Readiness in the field of dentistry.

Rural-urban disparities in patient satisfaction with oral health care: a provincial survey.

Background: Identifying spatial variation in patient satisfaction is essential to improve the quality of care. Thus, the objective of this study was to investigate rural-urban disparities in patient satisfaction and to determine the factors that could influence satisfaction with oral health care.

Methods: Data from 1788 parents/caregivers of children who participated in the Quebec Ministry of Health clinical study were subject to secondary analysis.

Effects of nocturnal wearing of dentures on the quality of sleep and oral-health-related quality in edentate elders with untreated sleep apnea: a randomized cross-over trial.

Study Objectives: This study aims to assess whether the nocturnal wear of dentures has an effect on the quality of sleep and oral-health-related quality of life of the edentulous elderly with untreated sleep apnea.

Methods: A single-blind randomized cross-over design with two sequences and two periods was used. Participants (n = 77) were randomly assigned either to sequence 1 (nocturnal wear followed by nocturnal nonwear of the denture for 30-30 days) or sequence 2 (nocturnal nonwear followed by nocturnal wear of denture for 30-30 days).

A 5-Year Esthetic RCT Assessment of Anterior Maxillary Single-Tooth Implants with Different Abutment Interfaces.

Purpose: This study sought to define the tissue responses at different implant-abutment interfaces by studying bone and peri-implant mucosal changes using a 5-year prospective randomized clinical trial design study. The conus interface was compared with the flat-to-flat interface and platform-switched implant-abutment systems.

Materials And Methods: One hundred forty-one subjects were recruited and randomized to the three treatment groups according to defined inclusion and exclusion criteria.

The McGill Denture Satisfaction Questionnaire revisited: Exploratory factor analysis of a binational sample.

Objectives: To examine the McGill Denture Satisfaction Questionnaire (MDSQ) in terms of dimensionality, item reduction and construct validity in a binational sample of complete denture wearers.

Materials And Methods: We conducted secondary analyses of baseline data from two studies on implant-retained overdentures: a quasi-experimental study in the United States (n = 145) and a randomised trial in Brazil (n = 120). All participants wore upper/lower dentures and responded at baseline to the MDSQ items concerning their original mandibular dentures.
