About this study

Official title: TMJ Fibrocartilage Detection Using 3D Fat-Suppressed Spoiled Gradient-Echo Magnetic Resonance Imaging

Objective: The aims of this study will be to detect the fibrocartilage layer (FC) of the human temporomandibular joint (TMJ) using 3D SPGR (Spoiled GRASS sequence) (T1 WATS) sequence and to compare these results with those of conventional magnetic resonance imaging (DP, T2 MRI) sequences in patients with temporomandibular disorders (TMD).

Read the detailed description

This prospective and observational study will focused on analyzing morphological characteristics of the fibrocartilage layer of the TMJ based on the MRI scans of 59 patients. All 118 TMJs of these patients will be suitable for analysis, (range: 18-60 years old), females and males affected by TMD and did not undergo previous TMJ treatment.

    Also called T1 WATS

    MRI will be performed in the TMJ of participants affected with TMD

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Presence of the TMJ Fibrocartilage layer

    The fibrocartilage layer will be evaluated dichotomously (absent/present) Patients will be examined using bilateral MRI (Phillips Intera 1,5 T, Sense Flex S Dual Coil) in the sagittal PD-weighted, T2-weighted and T1-weighted WATS, all in the oblique axis of the mandible condyle and with a closed mouth; dynamic gradient-echo at open mouth at 10 mm, 20 mm and 30 mm of the interincisal distance. Additionally, a coronal PD-weighted sequence with the mouth closed will be performed. Of each TMJ will be taken with 8×8 cm FOV and 0.2 cm spacing. All sequences will carried out using the same equipment and on the same day.

    Measured: six months

  2. Discontinuity of the TMJ FC layer

    The TMJ fibrocartilage layer will be evaluated dichotomously (continuous/discontinuous).

    Measured: six months

  3. Fibrocartilage Signal Intensity

    Six regions of interest (ROIs) will be measured in the fibrocartilage layer of each TMJ. (anterior 0°, center 45° and posterior 90°), three in the mandibular condyle and three in the temporal fossa. The fibrocartilage signal intensity in each ROI will be expressed as the mean value of intensity units (Osirix).

    All measurements will be made in a simple blinded system by four different observers (ML, MN, CV, GZ) (chi-square test for interobserver agreement: p˂0.05). Measurements will be made separately in the three MRI sequences (length tool, Osirix Imaging software). In all MRI sequences, TMJ will be magnified at a zoom of 3.6. For the T1 WATS sequence, the window width will be set at 90 intensity Units (IU) (all values above +90 Hounsfield Unit (HU) will be white), and the window level was 80 (IU) (all values below +80 HU will be black). All images will be measured and stored in DICOM format., lengt

    Measured: six month

  4. Thickness of the TMJ fibrocartilage layer

    The TMJ FC thickness will be measured (curve tool, Osirix) and will expressed in millimeters.

    Measured: Six months

  5. Length of the TMJ fibrocartilage layer

    The lenght of the TMJ FC layer will be measured (curve tool, Osirix) and will expressed in millimeters.

    Measured: Six moths

  6. Statistical analysis

    The Shapiro-Wilk test and Levene's test will be performed to assess normality of data distribution and homogeneity of variance of the measurements, respectively.

    To determine the relationship between the presence or absence of fibrocartilage and the different sequences, Fisher's exact test will be used.

    The thickness, length and signal intensity of the fibrocartilage layer will be expressed as a mean value, separated by MRI sequence, and will be analyzed using descriptive statistics.

    SPSS v14.0 for Windows, statistical software will be used to perform data analysis.

    Measured: seven months
