ILA 3.1-4 Flashcards
Name 5 muscle-related TMDs
- Protective co-contraction
- Local myalgia
- Myofascial pain
- Myospasm
- Centrally mediated myalgia
What are some operator-related factors that affect restoration longevity?
- Level of experience
2. Restorative material choice
What tooth related factors can reduced restoration longetivity?
- Type of tooth - molars < premolars
- Tooth position
- Restoration design not suitable
- Restoration size was large
- High no of restorative surface
What are the three cardinal features of TMDs?
- Orofacial pain
- Joint noise
- Restricted jaw function
What things do you check for in a clinical exam to diagnosis TMD?
- Muscles of mastication - any tenderness or trigger points
2. Condyle - any sounds or pain, any deviation in opening or closing
What are the four phases of treatment planning?
- Emergency and stabilization
- Disease control and prevention
- Rehabilitation phase
- Recall and maintenance
Your patient comes in and complains of jaw discomfort and clicking. You suspect it could be a muscle related TMD. How would you manage the patient (briefly)?
- Reassure the patient
- Education - what is happening and why
- Dietary advice - soft foods; avoid hard and chewy foods
- Habit awareness and modification e.g. daytime clenching
- Occlusal splint
- Address contributing factors
What does COLDSPA stand for?
C - characteristic O - onset L - location D - duration S - spontaneity P - precipitating factors A - alleviating factors
What does shiny wear facets indicate?
Active tooth wear (attrition)
You suspect that your patient has a cracked cusp. How would you confirm this and how does the test work to give you a definitive diagnosis?
FracFinder;
Put over the suspicious cusp and get patient to bite down - pain upon release confirms cracked cusp.
Pressure upon biting down separates the teeth. Upon release, the tooth snaps shut and there is an inward flow of dentinal fluid, causing change in osmotic pressure and pain signal being sent to the pulp.
What are 4 types of inflammation of the TMJ?
- Synovitis
- Capsulitis
- Arthritides
- Retrodiscitis
What is the difference between micro and macrotrauma?
Microtrauma - any small force that is repeatedly applied
Macrotrauma - sudden force to the joint
T/F: in an open mouth trauma, the joint opposite the trauma receives the most injury.
True.
The same side condyle is well supported by the medial wall of the fossae.
What is arthritides?
A grouo of disorders in which destructive bony changes are seen.
Why is it important to get a detailed social history of a patient with jaw discomfort and muscle soreness?
To identify any psychosocial factors that could be contributing to the pain e.g. stress, quality of sleep
What is the difference in clinical presentation of disc displacement with and without reduction?
With reduction:
Clicking
Without reduction:
Closed lock and possible deflection to affected side
How may parafunction cause disc deplacement with reduction?
Parafunction may cause hypertrophy of lateral pterygoid muscle and cause disc to be pulled forward.
What is hypertranslation usually caused by?
- Anatomic irregularities
2. Habit patterns
T/F: subluxation is hypertranslation resulting in dislocation of the TMJ and presents as open lock.
False.
Subluxation is partial dislocation of TMJ, and patient is able to manipulate jaw closing themselves.
