In periodontal co-destruction theory, what is the primary role of occlusal trauma in the presence of plaque-induced periodontitis?
Answer: Acts as a co-destructive factor accelerating bone loss in already-inflamed tissue
Occlusal trauma acts as a co-destructive factor that accelerates alveolar bone loss when combined with existing plaque-induced inflammation, but does not initiate pocket formation alone.
What term describes the adaptive widening of the periodontal ligament space without attachment loss in response to increased occlusal forces?
Answer: Adaptive remodeling
Adaptive remodeling refers to the reversible widening of the PDL space that occurs when the periodontium accommodates increased occlusal loads without inflammatory bone loss.
Which clinical sign is MOST indicative of primary occlusal trauma in a periodontally healthy patient?
Answer: Pathologic tooth mobility with normal bone levels radiographically
Primary occlusal trauma manifests as tooth mobility from excessive forces on a periodontally healthy tooth with normal or slightly widened PDL space but no attachment loss.
Fremitus is best defined as which of the following clinical findings?
Answer: Vibration or movement of a tooth felt by the examiner's finger during occlusal contact
Fremitus is the palpable or visible movement of a tooth when the patient taps or moves through occlusal contacts, indicating excessive occlusal forces on that tooth.
According to the 2017 World Workshop classification, occlusal trauma is categorized under which major disease group?
Answer: Traumatic occlusal forces and occlusal trauma
The 2017 classification system places traumatic occlusal forces, including primary and secondary occlusal trauma, under a distinct category of periodontal conditions not caused by plaque.
When treating a patient with secondary occlusal trauma (reduced periodontium with normal forces), what is the FIRST priority in the treatment sequence?
Answer: Periodontal debridement and infection control
In secondary occlusal trauma, inflammation from plaque must be eliminated first before occlusal adjustments can be accurately assessed or performed.
