Radiographs & Periodontology, Basic Periodontal Examination & Clinical Decisions 8

?
When are horizontal and vertical bitewings used
horizontal:Where loss of attachment is slight, vertical:Where loss of attachment is moderate
1 of 16
under what headings is bone. loss described
distribution, pattern, severity
2 of 16
what is the distribution of bone loss
percentage of sites affected. localised <30% sites affected. generalised 30% sites affected , molar incisor
3 of 16
what is the pattern of bone loss. what is each patten associated with
horizontal bone loss- Associated clinically with suprabony pockets Vertical/angular bone loss-Associated clinically with infrabony pockets
4 of 16
What is a supra bony pocket and a infra body pocket
the base of the pocket is coronal to the level of underlying bone- supra bony. the base of the pocket is apical to the level of adjacent bone
5 of 16
what is the equation for the severity of bone loss
[(ACJ to bone crest )/ ACJ to root apex] x 100
6 of 16
what are the 4 levels of periodontal health
1. Pristine periodontal health (not likely) 2. Clinical periodontal health 3. Periodontal disease stability 4. Periodontal disease remission...
7 of 16
what are the elements included in the diagnosis of periodontal disease
extent- periodontitis- stage-grade-stability-risk
8 of 16
what is the stage and the grade
stage.- severity(- measure of destruction and damaged tissue due to periodontitis) and complexity of management.grade- rate of progression
9 of 16
talk. about each stage
stage I= Borderline between gingivitis and periodontitis. Stage II= Established periodontitis. Stage III= More destruction to support tissues • Patient at risk of tooth loss • Deep lesions may require referral
10 of 16
continued
Intraboney defects, furcations increased complexity of management • May warrant specialist referral • Patient has maintained functional occlusion so major rehabilitation not required. Stage IV=Considerable damage and loss of function
11 of 16
continued
Patient at risk of losing dentition • Deep lesions extend to apical portion of root • Hypermobility, occlusal trauma , drifting • Loss of aesthetics and function • Stabilisation of occlusion may be required • Specialist referral most likely warranted
12 of 16
what is Grade A periodontitis
Slow disease (% bone loss/age <0.5) (less than half patient’s age) • Mainly plaque driven, less plaque present than expected for disease seen • Less risk of disease recurring once stable.
13 of 16
what is Grade B periodontitis
Disease matches plaque present • % bone loss/age 0.5-1 (half patients age to patient’s age) • May have additional grade modifiers (risk factors) • Focus of treatment on plaque control and risk factor management • Probably require shorter recall time
14 of 16
what is Grade C periodontitis
High rate of destruction (than expected given plaque control) • % bone loss/age >1 (more than patient’s age) • More difficult to manage • Higher risk of relapse after • Will require short maintenance times • May require more aggressive approach to ma
15 of 16
What are the 3 stability options
Stable: • Bop < 10% • Pocket depths <4mm • In Remission: • Bop >10% • Pocket depths <4mm • No bop at 4mm pockets • Unstable: • pockets>5mm, or 4mm pockets display bop
