Deep learning-based automated diagnosis of temporomandibular joint anterior disc displacement and its clinical application.

Introduction: This study aimed to develop a deep learning-based method for interpreting magnetic resonance imaging (MRI) scans of temporomandibular joint (TMJ) anterior disc displacement (ADD) and to formulate an automated diagnostic system for clinical practice.

Methods: The deep learning models were utilized to identify regions of interest (ROI), segment TMJ structures including the articular disc, condyle, glenoid fossa, and articular tubercle, and classify TMJ ADD. The models employed Grad-CAM heatmaps and segmentation annotation diagrams for visual diagnostic predictions and were deployed for clinical application.

Early management of anterior disc displacement without reduction: Evaluating the effectiveness of modified arthroscopy discopexy with anterior disc repositioning splint.

Background: This study aims to assess the therapeutic efficacy of a modified arthroscopy discopexy suturing technique in combination with an anterior disc repositioning splint (ARS) for the treatment of early phase anterior disc displacement without reduction (ADDwoR) patients.

Methods: During 2021-2022, early phase ADDwoR cases were included and underwent modified arthroscopy discopexy suturing surgery and ARS therapy after surgery. Pre- and post-surgical evaluation parameters include the visual analogue scale (VAS) for pain, maximum mouth opening (MMO), and disc-condyle relationship on MRI.

Correlation Between Temporomandibular Joint Disc Perforation and Degenerative Joint Changes: A CBCT and Clinical Analysis.

Objectives: To analyse the correlation between temporomandibular joint (TMJ) disc perforation and degenerative joint changes (DJC) on cone-beam computed tomography (CBCT) and related factors.

Study Design: A total of 238 female patients with anterior disc displacement without reduction (ADDwoR), accounting for 348 affected joints, requiring TMJ disc open anchorage surgery were included in the study conducted from June 2021 to August 2022. Following TMJ disc open anchorage surgery, patients were divided into two groups: disc perforation (DP) and disc non-perforation (DNP).

Outcomes of Treatment With Manipulative Reduction Combine With the Disc-condyle Repositioning Splint in Acute Anterior Disc Displacement Without Reduction.

In this report, the authors describe a case of the acute anterior disc displacement without reduction treated by manipulative reduction combined with the disc-condyle repositioning splint to improve the limited mouth opening and relieve the pain, including diagnostic images and treatment performed.

Clinical Effects of the Combination of Rhytidectomy and Temporomandibular Joint Disc Repositioning Surgery.

Objective: This study aims to investigate the clinical effects of the combination of rhytidectomy and temporomandibular joint (TMJ) disc repositioning surgery in internal derangement (ID) stage IV-V and facial aging patients.

Methods: Eighteen facial aging with bilateral ID IV-V patients were enrolled in this study. All of them had undergone temporomandibular disc repositioning surgery and rhytidectomy by the same surgeon (Yao Min Zhu).

Outcomes of treatment with genioplasty and temporomandibular joint anchorage surgery.

Background: Anterior Disc Displacement without Reduction (ADDwoR) in adolescence can result in condylar resorption which produces mandibular retrusion/deviation (MR/D) in adulthood. This study aims to analyze the therapeutic effect of simultaneous genioplasty and temporomandibular joint (TMJ) anchorage surgery on ADDwoR with MR/D patients.

Methods: During 2016-2018, ADDwoR with MR/D cases were included and underwent TMJ anchorage surgery and genioplasty guided by digital design.

A nanostructured anti-biofilm surface widens the efficacy against spindle-shaped and chain-forming rod-like bacteria.

Current control of pathogenic bacteria at all biomaterial interfaces is poorly attuned to a broad range of disease-causing pathogens. Leading antimicrobial surface functionalization strategies with antimicrobial peptides (AMPs), defensins, have not shown their promised efficacy. One of the main problems is the lack of stability and swift clearance from the surface.

Synovial Chondromatosis of the Temporomandibular Joint: A clinical and arthroscopic study of 16 cases.

Objectives: Present and overview the clinical finding, management and arthroscopic study of Synovial Chondromatosis (SC) cases in Temporomandibular Joint (TMJ) treated by our team.

Study Design: During year 2008-2018, 16 TMJ SC cases were treated and reviewed. The clinical manifestations, radiographic data, arthroscopic study and pathologic findings were recorded and analyzed.

[Investigation of related risk factors of temporomandibular disorders in 109 patients].

Purpose: To investigate the related risk factors of temporomandibular disorders(TMD), and to provide evidences for clinical prevention.

Methods: One hundred and nine TMD patients were included in the study as case group, while 109 people with no TMJ symptoms and signs were selected randomly as control group. All subjects fulfilled questionaires.

[Effect of metallothionein on myocyte apoptosis and energy supply of isolated rabbit heart muscle during perfusion with ropivacaine].

Objective: [corrected] To assess the effects of metallothionein on myocyte apoptosis and energy supply of isolated rabbit heart muscle during perfusion with ropivacaine..

Methods: Sixty New Zealand white male rabbits were randomized into 3 equal groups.

Midazolam in rabbits terminates dysrhythmias caused by intracerebroventricular ropivacaine.

The current study was designed to investigate the mechanisms by which ropivacaine may act within the central nervous system (CNS) to produce cardiotoxicity. Eighty New Zealand rabbits were divided into four groups randomly. In Group 1, 20 rabbits received intracerebroventricular (icv) saline, and then received icv ropivacaine 30 min later.

Arthroscopic surgery for treatment of anterior displacement of the disc without reduction of the temporomandibular joint.

The aim of this study was to investigate the clinical results and efficacy of an arthroscopic approach to correct anterior displacement of the disc without reduction of the temporomandibular joint (TMJ) with limitation of mouth opening. We studied 28 joints with internal derangement in 23 patients, all of whom had had arthroscopic surgery (lavage, lysis of adhesions in the superior compartment, incision parallel to the disc-synovial crease of the upper joint compartment, and pull back of the anteriorly located disc). Objective and subjective data (increase in maximal interincisal opening, magnetic resonance imaging, and visual analogue pain score, VAS) were collected preoperatively and at 7, 30, 60 days, and 6 months or more postoperatively.
