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.

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).

Group 3 ITI Consensus Report: Patient-reported outcome measures associated with implant dentistry.

Objectives: The aim of Working Group 3 was to focus on three topics that were assessed using patient-reported outcome measures (PROMs). These topics included the following: (a) the aesthetics of tooth and implant-supported fixed dental prostheses focusing on partially edentulous patients, (b) a comparison of fixed and removable implant-retained prostheses for edentulous populations, and (c) immediate versus early/conventional loading of immediately placed implants in partially edentate patients. PROMs include ratings of satisfaction and oral health-related quality of life (QHRQoL), as well as other indicators, that is, pain, general health-related quality of life (e.

Pink Esthetic Score Outcomes Around Three Implant-Abutment Configurations: 3-Year Results.

Purpose: To evaluate the influence that three different implant-abutment interface designs had on peri-implant mucosal outcomes as assessed by the pink esthetic score (PES) 3 years after delayed implant placement and immediate provisionalization.

Materials And Methods: Adult subjects (n = 141) requiring replacement of a bounded single tooth in the anterior maxilla as well as first premolar sites were randomized to receive one of three unique implant-abutment interface designs (conical interface [CI]; flat-to-flat interface [FI]; or platform-switch interface [PS]). Treatment included immediate provisionalization with prefabricated titanium abutments, followed by custom computer-aided design/computer-aided manufacturing (CAD/CAM) zirconia abutments and cement-retained, all-ceramic crowns delivered after 12 weeks.

The patient general satisfaction of mandibular single-implant overdentures and conventional complete dentures: Study protocol for a randomized crossover trial.

Background: Mandibular overdentures retained by a single implant placed in the midline of edentulous mandible have been reported to be more comfortable and function better than complete dentures. Although single-implant overdentures are still more costly than conventional complete dentures, there are a few studies which investigated whether mandibular single-implant overdentures are superior to complete dentures when patient general satisfaction is compared. The aim of this study is to assess patient general satisfaction with mandibular single-implant overdentures and complete dentures.

Do traditional techniques produce better conventional complete dentures than simplified techniques? A 10-year follow-up of a randomized clinical trial.

Objectives: The use of a simplified method (S) of fabricating complete dentures has been shown to be more cost-efficient than the traditional method (T), and there are no negative consequences that detract from the cost savings in the short term. However, it is not clear whether this remains constant over a decade. The objective of this study was to clarify patients' perspectives and determine any differences between the dentures fabricated with these two different techniques after a decade of use.

Assessing Dental Students' Readiness to Treat Populations That Are Underserved: A Scoping Review.

In North America, all dental schools have adopted some form of community-based dental education (CBDE) or service-learning, but little is known about the areas being researched and reported in published studies. The aim of this study was to conduct a scoping review to determine what areas of research had been conducted to determine the effects of CBDE on dental students' readiness to treat populations that are underserved. A systematic search of articles published in English or French since 2000 was performed on July 29, 2015, and combined quantitative and qualitative synthesis of data was conducted.

Single-implant overdentures retained by the Novaloc attachment system: study protocol for a mixed-methods randomized cross-over trial.

Background: Overdentures retained by a single implant in the midline have arisen as a minimal implant treatment for edentulous mandibles. The success of this treatment depends on the performance of a single stud attachment that is susceptible to wear-related retention loss. Recently developed biomaterials used in attachments may result in better performance of the overdentures, offering minimal retention loss and greater patient satisfaction.

Rural-urban disparity in oral health-related quality of life.

Objectives: The objective of this population-based cross-sectional study was to estimate rural-urban disparity in the oral health-related quality of life (OHRQoL) of the Quebec adult population.

Methods: A 2-stage sampling design was used to collect data from the 1788 parents/caregivers of schoolchildren living in the 8 regions of the province of Quebec in Canada. Andersen's behavioural model for health services utilization was used as a conceptual framework.

Patient satisfaction with laser-sintered removable partial dentures: A crossover pilot clinical trial.

Statement Of Problem: Clinical data regarding newly introduced laser-sintered removable partial dentures (RPDs) are needed before this technique can be recommended. Currently, only a few clinical reports have been published, with no clinical studies.

Purpose: This clinical trial compared short-term satisfaction in patients wearing RPDs fabricated with conventional or computer-aided design and computer-aided manufacturing (CAD-CAM) laser-sintering technology.

In vitro comparison of two titanium dental implant surface treatments: 3M™ESPE™ MDIs versus Ankylos®.

Background: An ideal implant should have a surface that is conducive to osseointegration. In vitro cell culture studies using disks made of same materials and surface as of implants may provide useful information on the events occurring at the implant-tissue interface. In the current study, we tested the hypothesis that there is no difference in the proliferation and differentiation capacities of osteoblastic cells when cultured on titanium disks mimicking the surface of 3M™ESPE™ MDIs or standard (Ankylos®) implants.

Improving practice guidelines for the treatment of denture-related erythematous stomatitis: a study protocol for a randomized controlled trial.

Background: Denture-related erythematous stomatitis (DES) is a chronic biofilm-mediated disease, affecting one in every three complete denture wearers. Antifungals are the treatment most commonly prescribed by oral health professionals, based on the belief that colonization by Candida spp. is the main cause of DES.

Osseointegration of standard and mini dental implants: a histomorphometric comparison.

Background: Mini dental implants (MDIs) are becoming increasingly popular for rehabilitation of edentulous patients because of their several advantages. However, there is a lack of evidence on the osseointegration potential of the MDIs. The objective of the study was to histomorphometrically evaluate and compare bone apposition on the surface of MDIs and standard implants in a rabbit model.
