What is the BPE?
What is it used for?
Basic Periodontal Exam.
It is a screening tool only, NOT used for diagnosis.
It indicates what further level of examination is needed and provides basic guidance on treatment.
What are the scores on a BPE?
0 1 2 3 4 *
What does a code 0 BPE mean?
healthy tissue
<3.5mm probing depth
no bleeding
no calculus/overhangs
What does a code 1 BPE mean?
<3.5 probing depth
bleeding present
no calculus/overhangs
What does a code 2 BPE mean?
<3.5mm probing depth
sub or supragingival calculus/overhangs
What does a code 3 BPE mean?
shallow pocket
3.5-5.5mm probing depth
What does a code 4 BPE mean?
deep pocket
>5.5mm probing depth
What does a * on the BPE mean?
furcation involvement
In adults, what are teeth involved in the BPE recording?
in sextants
7-4, 3-3, 4-7 along upper and lower arch
the 8s (third molars) are not included
In children, what are teeth involved in the BPE recording?
UR6, UR1, UL6
LL6, LL1, LR6
(remember: right, right, left - left, left, right!)
What treatment is required of a code 1 BPE?
Pi, Bi
OHI
Repeat BPE at next checkup appt
What treatment is required of a code 2 BPE?
Pi, Bi
OHI
fine scaling
Repeat BPE at next checkup appt
What treatment is required of a code 3 BPE?
Pi, Bi
OHI
Fine scaling (initial phase)
Consider radiographs
Repeat BPE after initial phase. If code 3 persists:
DPC in that sextant
Possible RSD on code 3 sextant
What treatment is required of a code 4 BPE?
Pi, Bi
OHI
Fine scaling (initial phase)
Full mouth DPC (at initial, post-initial and post-corrective)
Carry out radiographs: full mouth periapicals
After initial phase carry out RSD on sites
What type of radiograph is the gold standard used in periodontal assessment?
periapical radiograph using long-cone paralleling technique.
Provides information of entire root length
In periodontal assessment, what features are assessed in periapicals radiographs?
- degree of bone loss (as a %)
- type of bone loss (horizontal, vertical, bony defect)
- furcation involvement
- Subgingival calculus
- overhanging restorations
- perio endo lesions
- widened periodontal ligament
- abnormal root length/root morphology for RSD
- spaces for interdental aids, OHI
What are the types of furcation involvement?
(3 types: 3 syllables in fur-ca-tion)
Class I
Class II
Class III
What does a Class I furcation indicate?
Initial involvement.
Concavity felt with probe but does not enter furcation area.
Destruction <3mm deep
What does a Class II furcation indicate?
cul-de-sac involvement.
Probe able to partially enter furcation area.
Destruction >3mm deep
What does a Class III furcation indicate?
through and through involvement.
Probe completely passes through furcation.
Destruction extends across entire width of furcation
What are the types of mobility?
(4 types: 4 syllables in mo-bi-li-ty)
Grade 0: normal physiological movement <0.3mm
Grade 1: horizontal mobility 0.3mm-1mm
Grade 2: moderate horizontal mobility >1mm
Grade 3: severe horizontal >2mm or vertical mobility
What is the BEWE?
What is it used for?
Basic Erosive Wear Exam
Screening tool used alongside BPE to record and monitor erosive tooth wear
What questions would you ask when assessing someone’s risk of erosive tooth wear?
1) How many different dietary acids are consumed daily; fruits, anything with a fruit flavouring, acidic drinks, acidic sweets and medications?
2) How many of these are between meals?
3) Do you spend more than 10 minutes consuming any acidic food or drink at a single sitting?
4) Do you sip, swish, hold or rinse acidic drinks before swallowing?
5) Do you consume dietary acids at an increased temperature e.g. hot water with lemon, stewed fruits, fruit teas?
