Local predisposing factors Flashcards
What are local predisposing factors to periodontal disease?
Any factors that encourage plaque accumulation by inhibiting removal or allowing accumulation
List 6 anatomical local pre-disposing factors
Occlusion (traumatic overbite) Tooth arch relationship (crowded teeth) Root morphology - grooves, furcations Cervical enamel projections Enamel pearls Recession
List 7 acquired local predisposing factors
overhanging restoration Sub-gingival restorations Removable appliances Orthodontic appliances Open contacts Root fractures Root resorption
Akerly class II
Lower incisors occlude with and traumatise palatal gingival margin of upper incisors
Akerly class 3
Traumatic occlusion leads to stripping of lower labial and upper palatal gingiva
Akerly class 4
Incisors sheer past each other causing wear on palatal aspects of upper incisor and sometiem labial aspect of lowers
Akerly 1
Lower incisors occlude with palatal mucosa causing mucosal trauma
management of traumatic occlusion?
OHI - single tufted brush
Soft splint
Severe? - orthodontics
Anterior restorations to provide occlusal stops
Signs and symptoms of occlusal interferences?
Increasing mobility drifting pain TTP Tooth fracture Faceting of cusps Bruxism TMD
Primary vs secondary occlusal trauma
No existing periodontal disease
Existing periodontal disease
Treatment of primary occlusal trauma
Identify occlusal interference
Study models
Artiucaltor
Occlusal adjustment
Treatment of secondary occlusal trauma?
Identify occlusal interference
Study models
Articulator
Occlusal adjustment and periodontal treatment
Management of root groove
OHI
Surgical exploration
Regenerative techniques
Make groove cleanable
Gingival recession classification
Type I - no loss of inter-proximal attachment. CEJ not detectable medially and distally
Type II - loss of inter-proximal attachment but less than or equal to buccal attachment loss
Type III - loss of inter-proximal attachment and more than buccal attachment loss
Furcation classification
I - horizontal loss of attachment <1/3 tooth width
II - horizontal loss of attachment >1/3 tooth width but not total width
III - through and through
