control is like the weather, everybody talks about it, but nobody does anything
about it. Your office may be, from what I estimate, one of about 80-90% of
offices that have no real inventory control system. The majority of the rest
have an “ordering system”, which tells them when to order and then helps them
place the order. The ones that tell them when are usually tie-tag systems.
Those that help them place the order allow them to go into the web portal of
the vendor and place orders using barcodes. I have run into a very small number
of offices that track inventory on a spreadsheet – a very labor-intensive way
of doing things.
an asset of your practice. There are only a handful of times that a dental
practice will take it seriously as an asset (Valuing A Medical or Dental Practice, 2015):
When selling the practice.
In the case of divorce.
When bringing in or separating from a partner.
In case of death.
When there is catastrophic damage: flood, fire,

keep a balance sheet or financial statement. Really, the only way you can see
your practice’s financial performance is to know, not just gross income then
subtracting the bills, but to account for the assets of the practice (Franzone, 2014).
First of all, let me confess that accounting was my weakest
subject when I was studying for my MBA. I strongly recommend that you have a
reputable accountant to help you with this portion of your practice. If you’re
using a bookkeeper, it’s still a necessity to have a good accountant to verify
and validate the bookkeeper’s work.
On the balance sheet, you’ll account for Assets and
Liabilities. This is not the place to go into the nuts and bolts of it, but an
example of an asset would be your inventory. A liability would be your supply
Legally, your dental supply inventory and instruments are
what are used in the ordinary course of your practice’s business and
operations. You should have a sufficient, but not an excessive, amount of
inventory in stock to be able to meet your practice’s normal business and
operational needs. (Prescott, 2001, p. 32)
A successful business will keep a running total of their
inventory. The most accurate way to do this is to shut-down once a month for a
day and get the entire staff to count every item in the office. I don’t have to
tell you that this is not desirable nor practical.
The second most accurate, and the least labor intense is to
track inventory levels in a database. As inventory is removed or added, it is
reflected in the “virtual” inventory. A running count is kept by the system.
Then the data is verified by periodically checking the actual inventory against
the database. For example, once a quarter choose 10 items at random, count
them, and see how well they match the virtual inventory. If there are a few
small errors, then there are no real worries (unless those particular errors
show up consistently). But, if you see
errors throughout the system you may have a problem. It may be relatively
benign, such as employees not complying with taking inventory in and out from
the virtual system. Unfortunately, it could also be a sign that your inventory
is growing legs and walking over to eBay.
Misappropriation of supplies is becoming more common than
you may think. This is primarily due to
the fact that most offices have no idea what they have on the shelves. Think
about your practice for a minute. Would you miss the occasional ream of printer
paper that an employee might decide they’ll “borrow” until they can get over to
Staples? What about a package of burs here, a vial of endo posts there? Is that
handpiece that you put away in the lab because you’re not using it going to be
there when you decide to donate it to your local clinic?
So, here’s what you’ll require in an inventory control
All orders are placed and received through the
All inventory is removed from the system when it
is taken out of storage to be used in the operatories or lab.
A minimum of inventory is kept in stock. I agree
with one of the major vendors who recommend that the maximum of a month’s worth
should be on your shelves at any one time.
The minimum amount of inventory on your shelves
should be just enough to protect you from backorders; perhaps 2 weeks’ worth.
You should be able to get a snapshot of your
inventory on-hand with a minimum of effort. (Quick – How many boxes of gloves
do you have in stock right now? Will it be enough? Is it too much?) You ought
to be able to find that data out without moving from your office chair.
Compliance should take a minimum of effort on
the part of your staff.
There is an inventory control system that can do for you all
of this and more. You can find it at
In summary, inventory is an important asset of your dental
practice. As such, it needs to be accounted for and controlled. There is one
inventory control system on the market that will accomplish for you all of
this, and more. It’s called “Grasshopper
