Abnormal static and dynamic brain function in patients with temporomandibular disorders: a resting-state functional magnetic resonance imaging study.

Objectives: This study was conducted to investigate the brain function of patients with temporomandibular disorders (TMD) by combining the static and dynamic amplitudes of low-frequency fluctuation (ALFF).

Methods: Thirty patients with TMD and 20 healthy controls were enrolled. All the participants completed their questionnaires, received clinical examinations, and underwent resting-state functional magnetic resonance imaging scanning.

The impact of media converge on complex networks on disease transmission.

In this paper, we propose an epidemic disease model about the effect of media coverage on complex networks, where the contacts between nodes are treated as a social network. We calculate the basic reproduction number R and get that the disease-free equilibrium is locally and globally asymptotically stable if R< 1, otherwise disease-free equilibrium is unstable and there exists a unique endemic equilibrium, and the disease is permanent. And two immunization strategies are considered: proportional and target immunization.

[The centric relation-maximum intercuspation discrepancy in adult angle's class II pretreatment patients].

Objective: This study investigates the differences in condylar position between centric relation (CR) and maximum intercuspation (MI) in Angle's Class II orthodontic patients before treatment.

Methods: 80 cases, who were Angle's Class II pretreatment patients, and 50 cases, who were normal(ideal) occlusion were accepted. Dental casts were mounted on Panadent articulator with CR bite record, taken by bilateral manipulation and load testing.

[The measurement of utility value for skeletal malocclusion].

Objective: To measure the utility value of different skeletal malocclusion for patients receiving orthodontic treatment.

Methods: Utility value of different skeletal malocclusion for patients was measured by rating scale and time trade-off.

Results: The youth group had higher utility values than adult group for skeletal malocclusion Class II (protruding facial type) with median mandibular angle.

Correlation between centric relation–maximum intercuspation discrepancy and temporomandibular joint dysfunction.

Objective: To investigate the relationship between centric relation-maximum intercuspation (CR-MI) discrepancy and temporomandibular joint dysfunction (TMD) in pre-treated orthodontic patients.

Material And Methods: The study involved an experimental group of 107 pre-treated orthodontic patients with signs and symptoms of TMD aged 18-32 years, and a control group of 70 students with no signs and symptoms of TMD aged 20-30 years. The psychological condition of subjects was evaluated using two standard questionnaires, and a clinical examination performed to assess masticatory musculature and temporomandibular joint (TMJ) function, and to establish the presence or absence of TMD.
