About this study

This study will be designed to provide a comparison between the effect of the Rocabado approach as a conservative treatment and temporomandibular joint arthrocentesis in temporomandibular joint disc displacement without reduction.

Delimitations:

This study will be delimited in the following aspects:

  • Patients:

The study group will be composed of sixty-eight patients with temporomandibular joint disc displacement without reduction will be enrolled in the study. Group A: It will be composed of thirty-four patients with TMJ disc displacement without reduction who are started on the Rocabado approach- 4 - 6×6 exercise program. Include therapeutic exercise, and patient education focusing on the temporomandibular joint. Repeat measurements will be performed on 1st measurement at the baseline before any intervention, 2nd measurement after 8 weeks of treatment by a physiotherapist. Group B: It will be composed of thirty-four patients with disc displacement without reduction who are started on TMJ arthrocentesis procedure with medical and nursing care.

  • Equipment and tools:

2.1-Measurement equipment: Thera bite ROM scale 8-Item Jaw Functional Limitation Scale (JFLS-8) (Valid Arabic version) visual anlogue scale 2.2-Therapeutic procedures: Rocabado's 6X6 Exercise Program and manibulation

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • History of a sudden reduction in the mandibular opening. Unassisted mandibular opening 35 mm.
  • Mandibular opening with assistance increased by ≥3 mm from
  • unassisted opening, with a prior history of click, click disappearance, and a sudden decrease in opening.
  • Magnetic resonance imaging (MRI) diagnosis of Disc displacement without reduction.
  • Persistence of the symptoms indicated in the first item for a Maximum of 3 weeks.
  • clinical diagnosis of unilateral Disc displacement without reduction of the temporomandibular joint.

Exclusion criteria

  • History of major jaw trauma.
  • Dentofacial deformity.
  • Psychiatric illness.
  • Chronic headache. Presence of other disorders involving the TMJ.

Treatment and study plan

Rocabado approach exercise program 6×6 and manibulation .

Procedure

Rocabado's approach (Rocabado's 6 × 6 Exercises and manipulation). This program included 6 exercises to be performed 6 times a day, repeated 6 times, and three gliding exercises.

Arthrocentesis

Procedure

Participants in the Control Group underwent arthrocentesis of the affected temporomandibular joint. The procedure was performed as follows:

Anesthesia: Local anesthesia was administered to the area surrounding the TMJ.

Needle Insertion: A 20-gauge needle was inserted into the upper joint space approximately 10 mm anterior to the tragus.

Lavage: The joint was lavaged with lactated Ringer's solution to reduce inflammation and remove debris. The joint was irrigated with lactated Ringer's solution.

Other names: TMJ joint washing

Primary outcomes

  1. Thera Bite RANGE OF MOTION scale

    Time frame: pre treatment and eight weeks post treatment

    Will be used for measuring the Maximal interincisal opening, lateral movement will be measured.

    Measuring Maximal Interincisal Opening :

    • Patient Positioning: The patient opens their mouth as wide as possible without discomfort.
    • Scale Placement: The range of motion scale is positioned so that the notch rests on the edge of the lower incisor.
    • Measurement: Rotate the scale until it contacts the upper incisor, and record the reading at the point of contact.

    Measuring Lateral Excursion Movement:

    • Scale Alignment: Rest the range of motion scale against the lower incisors with the upper and lower teeth closed together.
    • Arrow Alignment: Align the arrow on the scale with an interproximal space between two upper teeth.
    • Measurement: Move the mandible laterally (side-to-side) and record the measurements on the lateral side.

  2. 8-Items Jaw Functional Limitation Scale

    Time frame: pre treatment and eight weeks post treatment

    Disability related to orofacial pain, which makes it a generic tool that one can use it for different types of orofacial pain conditions.

    • Preparation: Select a quiet and distraction-free environment.
    • Understanding the Scale: Rate each item on a scale from 0 (no limitation) to 10 (severe limitation).
    • Completing the Questionnaire: Carefully read each question and reflect on your jaw function over the past week.
    • Items to Rate: Assess difficulties in chewing, mouth opening, and emotional expression.
    • Time Required: Completion typically takes less than 5 minutes.
    • Post-Completion: Higher scores indicate greater functional limitations.

  3. Visual analog scale

    Time frame: pre treatment and eight weeks post treatment

    One of the pain rating scales,

    • Preparation: Ensure the VISUAL ANALOG SCALE line is accurately printed to scale (10 cm) with endpoints labeled:
    • 0 = No pain.
    • 10 = Worst imaginable pain.
    • Patient Instructions: Ask the patient to mark their current pain level on the line.
    • Score Measurement and Interpretation: Measure the distance in centimeters from the "no pain" end (0) to the patient's mark to determine the score out of 10. Higher scores indicate greater pain intensity (e.g., a mark at 6 cm corresponds to a pain level of 6/10).
    • Recall Period: Patients report either their current pain or pain experienced within the last 24 hours, depending on assessment context.
