How to Use This Calculator
  1. Enter Patient Uses per Day — the number of patients the instrument is used on daily.
  2. Select Instrument Type (Scaler, Curette, or Explorer) — scalers dull fastest due to calculus removal.
  3. Enter Working Days per Week — your typical clinical schedule.
  4. Review Sharpen Every (days) to get your recommended sharpening interval.
  5. Note Instrument Life (months) to plan your instrument replacement budget.

What each input means

Patient Uses per Day
Number of patients the instrument is used on per day
Instrument Type
Type of instrument — scalers dull fastest due to heavy calculus removal
Working Days per Week
Number of clinical days worked per week

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Patient Uses per Day = 8, Instrument Type = 1, Working Days per Week = 5 = 3 input(s) provided
  2. Calculate Sharpen Every
    Sharpen Every
    0.4 = 0.4
  3. Calculate Instrument Life
    Instrument Life
    0.4 = 0.4
  4. Calculate Annual Sharpenings
    Annual Sharpenings
    832 = 832
  5. Calculate Instrument Type
    Scaler = Scaler
