What is BPE?
What is BPE?
BPE is a simple, rapid screening tool indicating further examination levels and giving basic treatment guidance.
BPE sextant regions
BPE sextant regions
The dentition is divided into six sections, and the highest score is recorded for each. These sections include: Upper right (17 to 14), Lower right (47 to 44), Upper anterior (13 to 23), Lower anterior (43 to 33), Upper left (24 to 27), Lower left (34 to 37).
Which teeth are examined?
Which teeth are examined?
All teeth in each sextant are examined, with the exception of 3rd molars unless 1st or 2nd molars are missing.

Study Notes
- Bernoulli's principle states that for inviscid flow, an increase in speed occurs with a decrease in pressure or potential energy.
- Bernoulli's equation is: $\frac{v^2}{2}+gz+\frac{p}{\rho} = constant$
- $v$ is fluid flow speed
- $g$ is the acceleration due to gravity
- $z$ is the elevation above a reference plane
- $p$ is the pressure
- $\rho$ is the fluid density
Example: Airplane Wing Net Lift Force
- Pressure above the wing: $P_A = P + \frac{1}{2}\rho (v^2 - v_A^2)$
- Pressure below the wing: $P_B = P + \frac{1}{2}\rho (v^2 - v_B^2)$
- Net lift force on the wing: $F = (P_B - P_A)A = \frac{1}{2}\rho (v_A^2 - v_B^2)A$
