Effectiveness of synchronous teledentistry consultations in facilitating treatment compliance of rural pediatric patients.

Background: Limited access to pediatric oral health care in rural US areas is a substantial dental public health problem. In 2010, the Eastman Institute for Oral Health at the University of Rochester, initiated a synchronous teledentistry program to enhance oral health screenings, treatment planning, and treatment completion for rural pediatric patients who reside in the Western region of New York.

Methods: Data from dental records of all pediatric patients who were participants in the teledentistry program from its inception on April 13, 2010 through December 31, 2022, were reviewed.

Bioprinting of Aptamer-Based Programmable Bioinks to Modulate Multiscale Microvascular Morphogenesis in 4D.

Dynamic growth factor presentation influences how individual endothelial cells assemble into complex vascular networks. Here, programmable bioinks are developed that facilitate dynamic vascular endothelial growth factor (VEGF) presentation to guide vascular morphogenesis within 3D-bioprinted constructs. Aptamer's high affinity is leveraged for rapid VEGF sequestration in spatially confined regions and utilized aptamer-complementary sequence (CS) hybridization to tune VEGF release kinetics temporally, days after bioprinting.

Corrigendum to Incorporating new approach methodologies into regulatory nonclinical pharmaceutical safety assessment.

This corrects the article DOI: 10.14573/altex.2212081.

The role of regulatory focus types in the improvement of perinatal oral health knowledge among dental residents.

Objectives: This study aims to assess dental residents' perinatal oral health (POH) knowledge and Regulatory Focus Types' (RFT) impact on their knowledge before and after education.

Materials And Methods: A total of 53 dental residents from upstate New York participated from 2019 to 2021. A validated questionnaire collected demographic data, resident's POH knowledge, RFT, and self-reported burnout levels.

The role of in oral health: a review of current studies.

Background: Oral non-communicable diseases, particularly dental caries and periodontal disease, impose a significant global health burden. The underlying microbial dysbiosis is a prominent factor, driving interest in strategies that promote a balanced oral microbiome. , a gram-positive lactic acid bacterium known for its adaptability, has gained attention for its potential to enhance oral health.

Skeletal and dental open bite treatment using clear aligners and orthodontic miniscrew-anchored fixed appliances in permanent dentition: A systematic review.

Background: The objective was to systematically review studies assessing the efficacy of clear aligner therapy (CAT) and miniscrew-anchored fixed appliances (MAFAs) in the correction of skeletal and dental open bite in the permanent dentition.

Methods: A literature search was conducted across different databases, including PubMed, Cochrane Library, Science Direct, Web of Science, Medline, Scopus and Google Scholar, up to April 2024. Studies were chosen based on prespecified inclusion criteria.

Comparison of Flexural Strength and Wear of Injectable, Flowable and Paste Composite Resins.

(1) Objectives: This study investigated and compared the wear and flexural strength of two highly filled (injectable), one flowable and one paste composite. (2) Methods: Two highly filled flowable composites (G-aenial Universal Injectable and Beautifil Plus F00), a paste composite (Empress Direct) and a conventional flowable (Tetric EvoFlow) were tested. A two-body wear test was carried out using 10 disc-shaped samples from each group, which were subjected to 200,000 wear machine cycles to simulate wear, followed by Scanning Electron Microscope analysis.

Electrically-stimulated cellular and tissue events are coordinated through ion channel-mediated calcium influx and chromatin modifications across the cytosol-nucleus space.

Electrical stimulation (ES) through biomaterials and devices has been implicated in activating diverse cell behaviors while facilitating tissue healing process. Despite its significance in modulating biological events, the mechanisms governing ES-activated cellular phenomena remain largely elusive. Here, we demonstrated that millisecond-pulsed temporal ES profoundly impacted a spectrum of cellular events across the membrane-cytosol-nuclear space.

Correlation Between Orofacial Pain and Sensory and Autonomic Neuropathies.

Purpose: Orofacial Pain (OFP) affects 15% of the general population. OFP conditions can be myofascial, also known as temporomandibular disorders (TMDs) or neuropathic. The underlying pathophysiology in several chronic OFP conditions, is unknown.

Evaluation of Post-Operative Pain and Healing in Single-Visit versus Multiple-Visit Root Canal Therapy.

Background: " (RCT)" is a common endodontic procedure targeted at preserving teeth compromised by pulp infection. The debate over the optimal number of visits for RCT remains inconclusive, with single- and multiple-visit approaches both being advocated.

Methods: A prospective research was conducted on 100 subjects undergoing RCT at a tertiary care center.

Assessment of Factors Affecting the Success of Endodontic Retreatment Procedures.

Background: Endodontic retreatment is crucial for preserving dental health but is influenced by various factors.

Objective: This research aimed to assess factors affecting the success of endodontic retreatment procedures.

Methods: A retrospective analysis was conducted on 250 cases of endodontic retreatment.

Evaluating the Efficacy of Adjuvant Radiotherapy in the Management of Advanced Oral Cancer Cases.

Background: Because of its high rates of morbidity and death, especially in its late stages, oral cancer poses a serious threat to world health. Even with improvements in surgical and chemotherapeutic techniques, advanced oral cancer is still difficult to treat and frequently has unfavorable results.

Methods: Information on demographics, tumor features, treatment options, and results were gathered from medical records.

A qualitative study of preoperative anxiety in orthognathic patients: The patient perspective.

Introduction: Increased preoperative anxiety may have an adverse impact on the patient experience. This qualitative study therefore aimed to explore those factors affecting anxiety in the approach to orthognathic surgery.

Methods: A total of 28 orthognathic patients who had completed their presurgical orthodontic treatment and were within 8 weeks before their surgery underwent one-to-one in-depth interviews.

International expert consensus statement: surgical failure in obstructive sleep apnea.

Purpose: Upper airway (UA) surgery is commonly employed in the treatment of patients with obstructive sleep apnea (OSA). The intricate pathophysiology of OSA, variability in sites and patterns of UA collapse, and the interaction between anatomical and non-anatomical factors in individual patients may contribute to possible surgical failures. This clinical consensus statement aims to identify areas of agreement among a development group comprising international experts in OSA surgery, regarding the appropriate definition, predictive factors in patients, and management of surgical failure in OSA treatment.
