Plaque score = 2 x 3 = 6 (maximum score = 12). But only 10% of plaque area is plaque thickness of 3, with e.g. 50% of thickness 2 and 40% of thickness 1. Recalculated to reflect thickness, score would be (2 x 0.1 x 3) = 0.6 plus (2 x 0.5 x 2) = 2 plus (2 x 0.4 x 1) = 0.8 = 3.4.
How do you score plaque and calculus?
Scoring Plaque and Calculus A subjective visual observation is the most commonly used technique to evaluate used plaque and calculus. The steps are non-linear (ordinal or qualitative data) – a score of 4 does not equal twice a score of 2. Result: Accuracy is questionable, and use of parametric statistical tests is questionable.
What is the thickness score of a plaque?
Thickness score in area of deepest stain = 3. Combination Plaque score = 2 x 3 =6 (maximum score = 12). But only about 10% of plaque area has thickness of 3, with e.g. 50% of thickness 2 and 40% of thickness 1. Recalculated to reflect varying thickness, score would be (2 x 0.1 x 3) = 0.6 plus (2 x 0.5 x 2) = 2 plus (2 x 0.4 x 1) = 0.8.
How can I measure my plaque score to track my brushing?
Thankfully there is a simple way for you to measure your plaque score to track your brushing effectiveness at home, all you need is a disposable mouth mirror and plaque disclosing tablets from any local pharmacy. Set aside some time once each week to perform the test.
What are the current subjective scoring methods for plaque?
Current Subjective Scoring Methods Cause Distortion Example: Extent coverage = e.g. 45% = Plaque Extent score is 2 (25- 49%). Thickness score in area of deepest stain = 3. Combination Plaque score = 2 x 3 =6 (maximum score = 12). But only about 10% of plaque area has thickness of 3, with e.g. 50% of thickness 2 and 40% of thickness 1.
What is a good plaque score percentage?
Whilst a full mouth plaque score of 20% and a full mouth bleeding score of 10% are the accepted standard with periodontal academics and specialists, these are mainly mentioned for patients post therapy in the maintenance phase following periodontal treatment.
What is a plaque index score?
The plaque index assesses the amount of dental plaque visible on the vestibular and lingual surfaces of all teeth, except the third molars. The bacterial plaque developer solution was used to define cumulative amounts of plaque with criteria from 0 to 5 [24. S.
How is dental PCR calculated?
Plaque Control Record (PCR) is a common and simple method of recording the presence of plaque on mesial distal, facial, and lingual surfaces at the gingival margin [7]. PCR index is calculated by dividing the number of plaque-containing surfaces by the total number of available surfaces.
What is a plaque free score?
The Plaque Free Score (PFS), which was developed by Grant, Stern, and Everett, measures location, number, and percentage of biofilm-free surfaces in the patient's mouth. It will also assess papillary bleeding upon probing. The PFS is a more positive motivator for the patient.
How do you measure plaque on teeth?
One method uses special tablets that contain a red dye that stains the plaque. You chew 1 tablet thoroughly, moving the mixture of saliva and dye over your teeth and gums for about 30 seconds. Then rinse your mouth with water and examine your teeth. Any red-stained areas are plaque.
Why is plaque score important?
The abbreviated plaque and bleeding scores used in HGDM are being used to determine patient engagement and to advance onto formal periodontal treatment. Therefore, these scores have been kept higher than the accepted standard for two main reasons: Partial mouth recording systems tend to under-estimate disease.
What is O'Leary plaque index?
The plaque control record (O'Leary index) appears to be a commonly used oral hygiene index for assessing oral health skills. This index provides sufficient information for patient education; however, the time involved in data collection reduces its value.
How do you calculate oral hygiene index simplified?
Plaque Index = Accumulated plaque scores on all surfaces/the number of surfaces Calculus Index = (buccal score + lingual score)/the number of surfaces; Simplified Oral Hygiene Index (OHI-S) = Plaque Index + Calculus Index.
How do you read a dental probing chart?

How is gum health measured?
Periodontal charting is the practice of using a periodontal probe to measure the distance between your gums and where they attach to your teeth. This area or space is often called a “pocket,” and the size of these pockets is an indicator of how healthy or unhealthy your gums and bone support are.
What is modified O Leary?
purpose of modified o'leary plaque index: this plaque index records the location, number and percentage of biofilm-free surfaces and is best suited for use with an individual patient for biofilmvisualization, patient insruction and positive reinforcement of personal plaque control behaviors.
What is measured in the biofilm index?
Biofilm optical density, measured as intensity reduction of a light beam transmitted through the biofilm, correlates with biofilm mass, measured as total carbon and as cell mass. The method is more sensitive and less labor intensive than other commonly used methods for determining extent of biofilm mass accumulation.
What is a band of plaque?
2. A thin continuous band of plaque (up to one mm) at the cervical margin of the tooth. 3. A band of plaque wider than one mm but covering less than one-third of the crown of the tooth. 4. Plaque covering at least one-third but less than two-thirds of the crown of the tooth. 5.
How long can you see plaque when brushing?
If using two-tone disclosing solution, the clinician and patient can see plaque that has been missed when brushing that day and areas that have been missed for longer than 24 hours. Disclosing can be incorporated into the patient’s home oral hygiene regime in the form of disclosing tablets.
What is the worst score for a mouth of 28 teeth?
The worst possible score in a mouth of 28 teeth is 168/168. This means that six surfaces of each of the 28 teeth have a pocket depth of at least four millimeters, as well as bleeding upon probing. Hopefully, you don't have any patients like this!
Do you know your periodontal health score?
Many people today know their blood pressure numbers, blood sugar scores, and cholesterol levels. They should know their periodontal health score as well. Lots of periodontal indices are used in research, but very few are used in practice.
Do you need a periodontal charting form to calculate PHI?
You don't need a particular periodontal charting form to calculate the PHI. Simply count the number of probing scores over three millimeters and the total number of bleeding points, and you have the score. One charting form does provide a space for calculating and recording the PHI score.
What is cardiac calcium score?
Cardiac Calcium Scoring (Heart Scan) The coronary arteries are the vessels that supply oxygen-rich blood to the heart. Plaque — made of fat, calcium and other substances — can build up and narrow or close the arteries. To detect this build-up, your physician may order cardiac calcium scoring — a test that is also known as coronary artery calcium ...
Where is the CAC test performed?
The procedure is performed at the University Imaging Center at UMMC. To make an appointment call 410-328-3225.
What is the purpose of a heart test?
The purpose of the test is to understand your risk of heart attack or disease, taking preventive or corrective measures based on the results. If you have any plaque present (a score greater than 0), your doctor may make recommendations for lifestyle changes, such as quitting smoking, eating better and exercising more.
