The Potential of Percent Agreement as an Adjunctive Diagnostic Tool for Acute Temporomandibular Disorder.

: It is well established that individuals with chronic temporomandibular disorder (TMD) exhibit differences in their physical and psychosocial characteristics from those with acute TMD. However, few studies have analyzed the physical and psychosocial characteristics of patients with acute TMD. The objective of this cross-sectional study is twofold: first, to ascertain whether there are differences in physical and psychosocial factors among patients with acute TMD based on the percent agreement between patient-reported pain sites and pain sites identified through standardized palpation and, second, to determine the potential of percent agreement as a diagnostic and prognostic factor.

Microbial Profiles in Oral Lichen Planus: Comparisons with Healthy Controls and Erosive vs. Non-Erosive Subtypes.

Recent studies have begun exploring the potential involvement of microbiota in the pathogenesis of oral lichen planus (OLP), yet comprehensive investigations remain limited. Hence, this study aimed to compare the microbial profiles in saliva samples obtained from patients with OLP against those from healthy controls (HC), along with a comparison between erosive (E) and non-erosive (NE) OLP patients. Saliva samples were collected from 60 OLP patients (E: = 25, NE: = 35) and 30 HC individuals.

A Comparison of the Condyle and Articular Eminence in Asian Juvenile Idiopathic Osteoarthritis Patients with Unilateral and Bilateral TMJ Involvement: A Retrospective Case-Control Study.

This study compared the condylar volume, length, and articular eminence (AE) characteristics of normal individuals to those with unilateral and bilateral juvenile idiopathic osteoarthritis (JOA). The 116 patients were divided into four groups: Control (n = 16), affected condyle of unilateral JOA (Aff-Uni) (n = 36), non-affected condyle of JOA (NonAff-uni) (n = 36), and bilateral JOA (Bilateral) (n = 28). The differences in condyle volume and length and AE were analyzed using ANOVA and Bonferroni post-hoc tests.

Establishment of quantitative indicators for an efficient treatment on masticatory muscle pain.

Background: Although several studies have investigated effective treatments for masticatory muscle pain (MMP), no unified conclusion has been drawn regarding the effectiveness of these treatments.

Objectives: This study aimed to define quantitative indicators for predicting the outcome of MMP treatment.

Materials And Methods: In total, patients aged 20-70 years were recruited and divided into the MMP (n = 24) and control (n = 36) groups, based on the presence of MMP according to the Diagnostic Criteria for Temporomandibular Disorders.

Correlation between Metal Ions and Cytokines in the Saliva of Patients with Oral Lichenoid Lesions.

Purpose: We aimed to investigate the effect of metal ions from oral prostheses (OPs) released into the saliva of patients with oral lichenoid lesions (OLLs).

Materials And Methods: Subjects (n=183) were divided into four groups according to the presence or absence of OLL and OP. Concentrations of the metal ions titanium, chromium (Cr), cobalt (Co), nickel (Ni), palladium (Pd), silver (Ag), platinum (Pt), gold (Au), and zirconium (Zr) were measured using a laser-ablation microprobe inductively coupled to a plasma mass spectrometer.

Infection Associated with Salivary Gland-A Narrative Review.

species are common global opportunistic pathogens that could repeatedly and chronically cause oral mucosa infection and create an inflammatory environment, leading to organ dysfunction. Oral infections may cause temporary or permanent damage to salivary glands, resulting in the destruction of acinar cells and the formation of scar tissue. Restricted function of the salivary glands leads to discomfort and diseases of the oral mucosa, such as dry mouth and associated infection.

Prediction of anterior open-bite development after stabilization splint treatment in patients with temporomandibular disorder.

Objective: To assess the dentoskeletal factors of patients with temporomandibular disorders (TMDs) that can predict anterior open-bite development after stabilization splint treatment (ST).

Methods: Eighty-seven TMD patients were classified into three groups according to the degree of overbite changes after ST. Statistically significant differences in dental and skeletal measurements before ST among the groups were investigated.

Local Injection of Growth Hormone for Temporomandibular Joint Osteoarthritis.

Purpose: Osteoarthritis (OA) of the temporomandibular joint (TMJ) elicits cartilage and subchondral bone defects. Growth hormone (GH) promotes chondrocyte growth. The aim of this study was to evaluate the efficacy of intra-articular injections of GH to treat TMJ-OA.

Characteristics of patients who perceive dental treatment as a cause of oral mucosal lesions.

This retrospective study aims to investigate the proportion and characteristics of patients who perceive dental treatment (DT) as a cause of oral mucosal lesions (OMLs). A total of 2,302 patients with OMLs visited the Oral Medicine Department of Pusan National University Dental Hospital. The patients were divided into a study group (280 patients who perceived DT as a cause of OMLs) and a control group (300 randomly selected patients).

Pattern analysis of patients with temporomandibular disorders resulting from unilateral mastication due to chronic periodontitis.

Purpose: The purpose of the present study was to perform a pattern analysis in patients with temporomandibular disorder (TMD) resulting from unilateral mastication due to chronic periodontitis.

Methods: Thirty participants with signs or symptoms of TMD who engaged in unilateral mastication due to periodontitis-related discomfort (test group) were selected. Another 30 subjects exhibiting signs or symptoms of TMD resulting from unilateral mastication not due to chronic periodontitis (control group) were also recruited.

Effect of stabilization splint therapy on glenoid fossa remodeling in temporomandibular joint osteoarthritis.

Purpose: The aim of this study was to evaluate, by CBCT superimposition, bone changes (cortical bone intactness, sclerosis and subchondral cyst) in the glenoid fossa related to stabilization splint (SS) therapy for temporomandibular joint osteoarthritis (TMJ OA) patients and to compare the effects for two groups, one that had undergone SS therapy and the other that had not.

Methods: This case-control study included 36 TMJ OA patients, 10 that had undergone SS therapy (the SS group) compared with 26 that had not (the non-SS group). Osseous changes in the glenoid fossa were evaluated based on superimposed CBCT images before and after treatment.

Selecting best-fit models for estimating the body mass from 3D data of the human calcaneus.

Body mass (BM) estimation could facilitate the interpretation of skeletal materials in terms of the individual's body size and physique in forensic anthropology. However, few metric studies have tried to estimate BM by focusing on prominent biomechanical properties of the calcaneus. The purpose of this study was to prepare best-fit models for estimating BM from the 3D human calcaneus by two major linear regression analysis (the heuristic statistical and all-possible-regressions techniques) and validate the models through predicted residual sum of squares (PRESS) statistics.

Aims: To examine the association between temporomandibular joint (TMJ) symptoms and the global self-rating of oral health, concerns about oral health, and a history of jaw injury or third molar extraction in a representative Korean population.

Methods: From the Korean National Oral Health Survey 2006, 4,546 adults aged 18 years and older were included in the analysis. The dependent variable was TMJ symptoms.

Validity of Demirjian's and modified Demirjian's methods in age estimation for Korean juveniles and adolescents.

In estimating age of juveniles and adolescents, the teeth are employed primarily because of its low variability and less affection by endocrine and nutritional status in development. Demirjian established criteria for evaluating maturity of teeth and his method has been used throughout the world. However, several studies showed the inappropriateness of Demirjian's method on populations other than the one it is based on.

[Fulminant hepatic failure with hepatitis B virus reactivation after rituximab treatment in a patient with resolved hepatitis B].

It is well known that the reactivation of hepatitis B virus (HBV) may occur as an acute hepatitis after chemotherapy or immunosuppressive therapy. Although most of these cases have been reported in HBsAg-positive patients, there have been a few reports of HBV reactivation in HBsAg-negative patients. There have been concerns for the need to screen the reactivation as well as anti-viral prophylaxis in HBsAg-negative patients with possible HBV occult infection who are planning to undergo chemotherapy or immunosuppressive therapy.
