Why Your Dentrix Perio Percentage Matters: Finding Hidden Gaps in Your Hygiene Systems

One of my favorite things I get to do when I work one-on-one with dental practices is what I call a practice assessment. I remote into the office’s Dentrix software and start looking around.

I review reports, scheduling systems, clinical documentation, notes, and workflows to answer one big question:

Is this team using Dentrix in the most effective way possible?

There are many numbers I review when evaluating the health of a dental practice, but one metric that always gives me insight into potential system gaps is the perio percentage.

Your perio percentage can tell a powerful story about your hygiene department, documentation systems, and patient care.

What Is Your Perio Percentage and Why Does It Matter?

Your perio percentage compares the amount of periodontal therapy being completed in your practice compared to preventive hygiene services.

This isn’t a number automatically calculated on a standard Dentrix report, but it is one of the numbers I always want to know during an assessment.

My friend and dental colleague Rachel Wall created a perio calculator that helps practices measure this number by reviewing codes like:

• D1110 adult prophylaxis
• D4910 periodontal maintenance
• D4341 scaling and root planing
• D4342 scaling and root planing

Once you calculate this percentage, you start getting a clearer picture of your hygiene systems.

Your perio percentage starts with having accurate data, and that begins with consistent periodontal charting. If your team struggles with completing perio charts during hygiene visits, I recommend reviewing my article on why periodontal charting is a non-negotiable diagnostic process. Without proper diagnostics, it becomes almost impossible to identify periodontal disease, create accurate treatment plans, and support the care your patients need.

According to research from the American Dental Association and American Academy of Periodontology, a significant percentage of adults have some level of periodontal disease.

So, when I see a practice with a perio percentage under 10%, that immediately tells me we need to look deeper.

Your Dentrix reports give you the data you need to evaluate your hygiene systems, but you also need to understand what those numbers mean and where your opportunities are.

A great resource I recommend is Rachel Wall’s Perio Percentage Calculator from Inspired Hygiene. This tool can help you evaluate your current perio percentage and identify opportunities to improve your periodontal therapy systems, patient care, and hygiene department performance.

Remember, this isn’t about creating more production. It’s about making sure your patients are receiving the level of care they truly need.

Three Reasons Your Dentrix Perio Numbers May Be Low

When I find low perio numbers during a practice assessment, it usually comes down to one of three things.

1. Your Team Is Not Diagnosing Periodontal Disease

The first possibility is a lack of diagnosis.

This often happens because the team is missing the right diagnostic information.

For example, I worked with a practice where the perio percentage was under 5%. When I looked inside Dentrix, I could not find perio charting documentation anywhere.

No perio charts.
No measurements.
No diagnostics.

Without periodontal charting, how can you properly diagnose periodontal disease?

The answer is you can’t.

Sometimes this happens because hygienists are running behind and feel like they do not have time to complete perio charting.

When that happens, we need to evaluate:

• Hygiene appointment flow
• Time management
• Clinical systems
• Automation opportunities
• Dentrix workflow efficiency

The goal is to create systems that allow your team to complete proper diagnostics consistently.

One of the biggest barriers I hear from hygienists is, “We don’t have enough time.” The good news is Dentrix has tools that can help streamline this process. I shared several workflow ideas, shortcuts, and technology solutions in my article on Dentrix perio charting tips for hygienists, including ways your team can improve efficiency while still capturing the documentation needed for diagnosis.

2. You Are Diagnosing Perio but Referring It Out

The second possibility is that your team is diagnosing periodontal disease, but you are referring treatment to a specialist.

That is completely fine.

However, we still need a way to track that.

If your Dentrix perio production looks low because treatment is being referred out, then I recommend reviewing your referral reports.

You should be able to identify:

• How many patients were diagnosed
• How many were referred
• Where those patients were sent

The data should tell the full story.

3. Your Team Has a Coding Problem

The third reason your perio percentage may be low is incorrect coding.

This is where things become more serious.

If your hygienist is performing periodontal therapy, documenting periodontal therapy, but billing the appointment as a regular prophy, that creates a major compliance concern.

Your clinical documentation, procedure completed, and billing code must match.

This is also why your Dentrix clinical notes are so important. Your documentation should always tell the complete story of what was diagnosed, what was recommended, and what treatment was completed. If you want to strengthen your documentation systems, read more about adding the “why” into your Dentrix clinical note templates so your notes support your clinical decisions and protect your practice.

Now, patients always have the right to decline recommended treatment. A patient diagnosed with periodontal disease may decide not to move forward with scaling and root planing.

In that situation, documentation becomes extremely important.

Your Dentrix clinical notes should clearly show:

• The diagnosis
• The recommended treatment
• The patient’s decision
• What service was actually provided

Clear documentation protects your practice and your patients.

Use Dentrix Data to Find Hygiene System Gaps

Your perio percentage is more than just a number.

It gives you insight into your systems.

A low percentage may reveal:

• Missing perio charting
• Lack of diagnosis
• Scheduling challenges
• Coding inconsistencies
• Documentation issues

Once you identify the gap, you can create a better workflow.

Dentrix gives you the tools to document, track, and support your periodontal program. The key is making sure your entire team is using those tools consistently.

A strong perio program improves patient care, strengthens your hygiene department, and helps create a healthier practice.

Frequently Asked Questions About Dentrix and Perio Tracking

How do I calculate perio percentage in Dentrix?

Dentrix does not automatically calculate perio percentage. You can calculate it by reviewing hygiene procedure codes such as D1110, D4910, D4341, and D4342.

Why is my practice perio percentage low?

Low perio numbers are usually caused by lack of diagnosis, referring periodontal treatment outside the practice, or incorrect coding.

Can Dentrix help improve periodontal workflows?

Yes. Dentrix tools like perio charting, clinical note templates, and reporting features help teams create consistent periodontal systems.

Why does perio documentation matter?

Accurate documentation ensures the diagnosis, treatment provided, and billing codes align, helping protect both the patient and the practice.

Building a Stronger Hygiene Department

If your perio numbers are lower than expected, don’t ignore them. Your data is trying to tell you something.

Start by reviewing your Dentrix workflows, your documentation habits, and your periodontal protocols.

Small improvements in your systems can create a healthier hygiene department, stronger patient care, and a more high-performing dental team.
