The PFS records the biofilm on four surfaces of each tooth. To calculate this score, multiply the number of teeth by four to determine the number of available surfaces, and then subtract the number of surfaces with biofilm from the total available surfaces to determine the number of biofilm-free surfaces.
What is a good plaque score percentage?

How is modified O'Leary score calculated?
- multiple # erupted teeth x4 to obtain available surfaces to score.
- total (add) # of biofilm free surfaces.
- divide total biofilm free surfaces into total available tooth surfaces.
- multiple number obtained in #3 times 100.
- percentage of biofilm free surfaces obtained.
What are the plaque indices?
Clinical plaque indices are used to evaluate the level and rate of plaque formation on tooth surfaces, and to test the efficacy of oral care products for removal and prevention of plaque deposits from these surfaces.How is BOP calculated in dentistry?
The number of sites where bleeding is recorded is divided by the total number of available sites in the mouth and multiplied by 100 to express the bleeding index as a percentage.
What is a bad plaque score?
A score of 400 or more means you have a build-up of plaque and puts you at high risk of a heart attack within 10 years. A score of 1,000 plus means you have up to a 25% chance of having a heart attack within one year without appropriate medical treatment.
What is the 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. … A new oral hygiene index was developed based on the concepts of the Periodontal Screening and Recording (PSR). The highest score obtained in each buccal and lingual sextant is recorded.
Which does a score of two on the plaque index indicate?
ScoreMeasure used to determine plaque score1No plaque.2A thin continuous band of plaque (up to one mm) at the cervical margin of the tooth.3A band of plaque wider than one mm but covering less than one-third of the crown of the tooth.How is perio percentage calculated?
Periodontal Percentage = B/A The periodontal percentage looks at your definitive non-surgical periodontal therapy codes measured against the number of adult prophys performed in your practice.
What are Ramfjord teeth?In addition, Ramfjord recommended the assessment of six ‘index teeth’ that soon became known as the ‘Ramfjord teeth’ These teeth (with the notation of the Fédération Dentaire Internationale) were: maxillary right first molar (tooth 16), maxillary left central incisor (tooth 11), maxillary left first bicuspid (tooth 24) …
Article first time published onHow do you calculate Dmft and Dmfs?
Definition: DMFT is the sum of the number of Decayed, Missing due to caries, and Filled Teeth in the permanent teeth. The mean number of DMFT is the sum of individual DMFT values divided by the sum of the population. The 12-year-old is one of the WHO indicator age groups.
How do you calculate PCR for dental hygiene?
PCR index is calculated by dividing the number of plaque-containing surfaces by the total number of available surfaces. In addition, Patient Hygiene Performance (PHP) is useful for evaluating the extent of dental plaque on the tooth surface [8].
What does the gingival index measure?
The Gingival Index (GI) scores each site on a 0 to 3 scale, with 0 being normal and 3 being severe inflammation characterized by edema, redness, swelling, and spontaneous bleeding4 (Table 2-2). This measurement is based on the presence or absence of bleeding on gentle probing.
What is dental calculus?
Dental calculus is calcified dental plaque, composed primarily of calcium phosphate mineral salts deposited between and within remnants of formerly viable microorganisms. A viable dental plaque covers mineralized calculus deposits.
What is furcation area?
1. Furcation is the anatomical area where the roots divide. Therefore, furcation defect (also called furcation involvement) refers to bone loss at the branching point of the roots. Furcation can only be present on multi-rooted teeth, not single-rooted teeth.
What is osseous crater?
Osseous crater is another type of bone loss in which concavities in the crest of the interdental bone are confined within the facial and lingual walls [Figure 2]e.
What does bleeding on probing indicate?
BoP is a sign of periodontal inflammation and indicates some sort of destruction and erosion to the lining of the sulcus or the ulceration of sulcular epithelium. The blood comes from lamina propria after the ulceration of the lining.
What is a basic periodontal examination?
Basic Periodontal Examination (BPE) Careful assessment of the periodontal tissues is an essential component of patient management. The BPE is a simple and rapid screening tool that is used to indicate the level of further examination needed and provide basic guidance on treatment needed.
Can you lower your calcium score?
If your calcium score is high, medication and procedures that remove plaque from the heart can lower the score.
Do statins clear the arteries of plaque?
A: Yes. There have been several clinical studies — many of them done here at Cleveland Clinic — that show statins can reverse plaque buildup. Two statins in particular, atorvastatin, which is sold under the brand name Lipitor, and rosuvastatin, which is sold under the brand name Crestor, are the strongest statins.
What is considered a high cardiac calcium score?
A score of 100 to 300 means moderate plaque deposits. It’s associated with a relatively high risk of a heart attack or other heart disease over the next three to five years. A score greater than 300 is a sign of very high to severe disease and heart attack risk.
What is the Volpe Manhold index?
The Volpe–Manhold index is a method to quantify calculus formation measurements on lingual surfaces of anterior lower teeth using a periodontal probe [13]. … The control group was made up of patients who maintained good plaque control and formed little calculus.
What is the periodontal disease index?
The PDI is the total of the scores for each tooth divided by the number of teeth examined: the higher the score, the more severe the periodontal disease.
What is pocket depth?
Measure the pocket depth of the groove between your gums and teeth by placing a dental probe beside your tooth beneath your gumline, usually at several sites throughout your mouth. In a healthy mouth, the pocket depth is usually between 1 and 3 millimeters (mm). Pockets deeper than 4 mm may indicate periodontitis.
What is PCR in dentistry?
Abstract. Polymerase chain reaction (PCR) has become a popular diagnosis and research technique in dentistry. Several studies show that high sensitivity and specificity of PCR method allows it to be as a precise, efficient, and rapid method for detection, identification, and quantification of microorganisms.
