Three-Dimensional Assessment of Dental Enamel Microcrack Progression After Orthodontic Bracket Debonding Using Optical Coherence Tomography.
J Funct Biomater
December 2024
Department of Orthodontics, School of Dentistry, Kyungpook National University, Daegu 41940, Republic of Korea.
The current study aimed to quantify the length progression of enamel microcracks (EMCs) after debonding metal and ceramic brackets, implementing OCT as a diagnostic tool. The secondary objectives included a three-dimensional assessment of EMC width and depth and the formation of new EMCs. OCT imaging was performed on 16 extracted human premolars before bonding and after debonding.

Oral ulcer wounds are difficult to heal due to bacterial infections, persistent inflammatory responses, and excessive reactive oxygen species (ROS). Therefore, the elimination of bacteria, removal of ROS, and reduction of inflammation are prerequisites for the treatment of mouth ulcer wounds. In this study, oligomeric proanthocyanidins (OPC) and 3-(aminomethyl)phenylboronic acid-modified hyaluronic acid (HP) were used to form polymer gels through dynamic covalent borate bonds.

Background: Short dentin etching, a relatively recent technique, aims to improve resin-dentin bonding by preserving hydroxyapatite crystals within the collagen spaces. This study explores short dentin etching's potential in mitigating over-etching issues in deep proximal dentin/cementum margins, an aspect not previously investigated. This study evaluates the microtensile bond strength (μTBS) and marginal adaptation of two universal adhesives using different etch-and-rinse strategies (15-second and 3-second etching) and self-etch strategies, both immediate and post-thermal cycling and mechanical loading.

Faculty of Dentistry, Van Lang University, Ho Chi Minh, Vietnam.
Objective: This study aims to evaluate the clinical transfer accuracy of partially enclosed single hard vacuum-formed trays based on three-dimensional (3D) printed models for lingual bracket indirect bonding.
Materials And Methods: Thirty-two consecutive patients receiving lingual orthodontic treatment were enrolled. Digital models with ideal bracket positions were 3D-printed, followed by fabrication of partially enclosed single hard vacuum-formed trays.
Effectiveness of Transcutaneous Electric Nerve Stimulation for Controlling Pain after the Archwire Placement.

Department of Orthodontics and Dentofacial Orthopaedics, Saraswati Dental College, Lucknow, Uttar Pradesh, India.
Introduction: The aim of the study was to evaluate the effectiveness of transcutaneous electric nerve stimulation (TENS) for controlling pain after the archwire placement and then comparison between the placebo, extra-oral, and intra-oral group depending upon the electrode placement.
Materials And Methods: The study consists of a sample size of 90 patients who were further divided into three groups. Each group had 30 samples each, and the groups were divided into placebo group, extra-oral TENS group, and intra-oral TENS group.
