classification of periodontology Flashcards
what are the characteristics of gingivitis
bleeding, redness and swelling
reversible
different types
what are the characteristics of periodontitis
pocket dept increase, loss of attachment, bone loss
irreversible
different types
what were the key features in the 1999 classification
gingival diseases
perio classifications were chronic and aggressive
additional diseases
when did the new classification come out
november 2017 in chicago
what headings lie under perio health, gingival diseases, and other conditions
perio health and gingival health
gingivitis: dental biofilm induced
gingival diseases non dental biofilm induced
what headings are under periodontitis
NPD- necrotising perio disease
periodontitis
periodontitis as a manifestation of a systemic disease
what headings are under other conditions affecting the paeriodontium
systemic diseases and conditions affecting perio supporting tissues
perio abscesses and Endodontics perio lesions
mucogingival deformities and conditions
traumatic occlusal forces
tooth and prosthesis related factors
what headings are under peri implant diseases and conditions
peri implant health
peri implant mucositis
peri implantitis
peri implant soft and hard tissues deficiencies
what gives the extent of gingivitis
percentage bleeding on probing
what counts as a healthy periodontium
less than 10% bleeding sites and depts of 3mm or less
what is gingivitis medical biofilm induced related with
associated with dental biofilm alone
mediated by local or systemic factors
drug influenced gingival enlargement
what is gingivitis dental biofilm induced-with systemic risk factors
mediated by systemic factors such as associated endocrine functions-puberty/mensuration associated gingivitis
pregnancy associated gingivitis- pregnancy epulis pyogranic epuloma
diabetes associated gingivitis
associated with blood dycrasias:
leukaemia associated gingivitis
what can plaque induced gingivitis be exacerbated by
hyperglycaemia
which drugs can influence gingival enlargement
phenytoin- epilepsy
calcium channel blockers-amlodipine, nifedipine diltiazam
ciclosporin- immunosuppressant after heart/kidney replacement
what can influence dental non biofilm induced
genetic and developmental disorders specific infections inflammatory and immune systems reactive processes neoplasms traumatic gingival pigmentation endocrine, nutritional and metabolic function
what does necrotising gingivitis look like clinically
punched out interdental gingiva
how do we classify periodontitis
extent stage grade stability and risk factors
what are the stages
stage 1: initial
stage 2: moderate
stage 3:severe potential additional tooth loss
stage 4:potential loss of dentition
HOW IS extent and distribution characterised
generalised
localised
molars/incisors
what are the grades
grade A slow less than 0.5
grade B moderate 0.5-1.0
grade C rapid rate of progression greater than 1.0
how do we write a diagnosis statement
extent- periodontitis-stage-grade-stability- risk factors
what is the stage
extent of clinical attachment loss or bone loss
what is the grade
to indicate the rate of progression,responsiveness to standard therapy and potential impact on systemic health
what do we consider for the assessment of current perio status
currently stable
currently in remission
currently unstable
what are the characteristics of current stable assessment of current perio status
BoP less than 10%
probing pocket depth- less than or equal to 4mm
No BoP at 4mm sites
what are the characteristics of current in remission assessment of current perio status
BoP greater than or equal to 10%
PPD less than or equal to 4mm
no BoP at 4mm sites
what are the characteristics of current unstable assessment of current perio status
PPD greater than or equal to 5mm or
greater than or equal to PPD and BoP
how do we calculate grading
% bone loss divided by the age of the patient
what will radiographs need to be reviewed to determine
distribution of extent
worst affected site for staging
percentage bone loss in relation to age for grading
