diagnosis and classification of PDD Flashcards
2017 classifications involved in PDD
1) periodontal health, gingival conditions and diseases
2) periodontitis
3) other conditions affecting the periodontium
4) peri implant diseases and conditions
staging and grading system
4 stages of severtiy (1-4)
3 grades based on disease succeptibiloty
WHO health
- health is a complete sate of physical mental and social wellbeing and not merely absence of disease and infirmity
periodontal and gingival health
abscence of clinically detectable inflammation
bone levels 1-3mm apical to CEJ
clincial health can be restoed following treatment of gingivitus and PDD
gingivitus dental biofilm induced
An inflammatory lesion resulting from interactions between plaque and the hosts immune inflammatory response
confined to gingiva
diagnosing gingivitus
more than 10% bleedingsites
risk factors
Local risk factors - retentive factors - removal will reduce plaque retention Systemic risk factors - smoking - offer smoking cessation - root surface debridement would not be feasible
drug induced gingival enlargment
consult with doctor to change medication
gingival diseases non dentlalbiofilm induced
conditons not caused by plaque and not resolved following plaque removal
- inflammation may be beyond the mucogingival junction
forms of PDD
necrotising PDD
peridontisis as a manifestation of systemic disease
peridonttis
necrotising PDDs
necrotising gingivitus
necrotising periontitis
necrotising stomatitis
necrotising gingivitus symtoms
- gingiva inflamed and red
- dental papilla has broken down
- gingivitis so no bone loss
- ulceration, necrosis, pain, halitosis
necrotising periodontits l
loss of supporting strucutre and bone loss
necrotising stomatitis
loss of flesh
genetic disroders involved in peridonttis as a manifestation of systemic disease
erlos danlos syndrone
papillion lefeve
Ehleres Danlos syndrome
- heteroflexibility of joints
- increased bleeding and bruising
- hyper extensible skin
- underlying molecular abnormality of collagen
papillion lefevre
- affects primary and secondary dentition
- normal dental development until hyperkeratosis of palms and soles appear
- mechanism poorly understood
- mobility , periodontal destruction, bone loss, loss of teeth, breakdown of supporting tissues, inflamed gingiva
orgin of periodontits associated with endodontic lesions
1) periodontal origin
2) endodontic origin
3) combination of both
periodontitis clincial showings
- inflame gingiva
- gingival recession
- loss of dental papilla
- abscesses
- bleeding inflamed
stages of peridontitis
Stage I: Initial periodontitis
Stage II: Moderate periodontitis
Stage III: Severe periodontitis
Stage IV: Very severe periodontitis
grades of periodontitis
i. Grade A: slow rate of progression
ii. Grade B: moderate rate of progression
iii. Grade C: rapid rate of progression
systemic diseases/condition affecting periodntal supporting tissues
genetic disorders
acquired immunodeificeicny diseass
inflammatory diseases
other systemic disorders
mucrogingival deformities and conditions indications t to chekc
- gingival phenotype
- interproximal attachment loss
- characteristics of exposed root surface
traumatic occlusal forces
any force which results injurt to the teeth
peri implant health
absence of erythema, bleeding on probing, swelling and suppuration
- No increase in probing depth compared to previous examinations
- Absence of bone loss beyond crestal bone level changes resulting from initial bone remodeling
periimplant mucositis
Characterized by bleeding on gentle probing, erythema, swelling and/or suppuration may be present
- Increased pocket depth often seen due to swelling or decrease in probing resistance
- Absence of bone loss beyond crestal bone level changes resulting from initial bone remodeling
what is peri implant mucosisis likely to be caused by
plaque biofilm
peri implantitis and what its characterised
Plaque associated pathological condition occurring in tissues around dental implants,
- characterised by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone(distal aspects of radiograph)
what is peri implant mucosisitis assumed to precede
peri implantitis
peri implant soft and hard deficienceis
diminited dimentsions of the alveolar process/ridge that reusult in both hard and soft tissues deficiences
risk factors associated with recession of peri implant musocsa
- Mispositioning of implants
- Lack of buccal bone
- Thin soft tissue
- Lack of keratinized tissue
- Surgical trauma
dignosis statment when dignosing PDD
- Determine type of disease
- Disease extent – localised/generalised/molar-incisor
- Stage – I, II, III, IV
- Grade – A / B / C
- Current disease status – stable/remission/unstable
- Risk factor profile – smoking/diabetes
