# What is approximal plaque index?

## What is approximal plaque index?

Approximal plaque index (API) is determined dichotomously in the first and third quadrants lingually and in the second and fourth quadrants buccally. Teeth are rinsed with a spray of air and water to remove any loose food remnants and materia alba.

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.

How do you calculate plaque index?

Plaque Index = (2+1+1+2) / 4 = 1.5, according to the plaque index system this means the plaque index for the tooth is moderate accumulation of soft deposit within the gingival pocket, or the tooth and gingival margin which can be seen with the naked eye.

### 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. This index provides sufficient information for patient education; however, the time involved in data collection reduces its value.

What is the most commonly used index to score plaque?

The most frequently referenced measure of supragingival plaque is the Plaque Index or PlI. The PlI is similar to the Gingival Index and uses an ordinal scale of 0 to 3. Similar to the GI, the PlI is scored on four sites per tooth.

How does the hygienist determine the plaque index for each patient?

Simply multiply the number of teeth by four to calculate the number of interproximal surfaces, or by six for the total number of surfaces measured. Patients with periodontal disease often start with scores of 25/100 to 85/140 or more. The numbers drop dramatically after therapy.

## How is plaque control record 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.

Which does a score of two on the plaque index indicate?

This index involves a scale from 0 to 3 for the buccal, lingual, mesial and distal surfaces that is scored as follows: 0 indicates healthy gums; 1 indicates slight color changes, light edema and no presence of bleeding on probing; 2 indicates edema with slight redness and bleeding on probing; and 3 indicates severe …

What is a Cpitn score?

Background: Community periodontal index of treatment needs (CPITN) index is commonly used to measure periodontal disease. It’s uniqueness, apart from assessing the periodontal status, also gives the treatment needs for the underlying condition.

### What is the most common index for plaque in clinical research trials?

The most frequently referenced measure of supragingival plaque is the Plaque Index or PlI.

What is a index in dentistry?

Dental indices are tools used to quantify dental diseases thereby cross comparisons can be made based on disease burden and treatment efficacy. In dental literature, there exists an ambiguity on selecting the ideal scale or index to measure dental diseases.

What does BOP mean in dental?

Bleeding on probing (BOP) is an indicator of tissue inflammatory response to bacterial pathogens. Due to anatomical limitations, the entity and physical state of microbial aggregations located under the gingival margin and their relations to BOP have been hardly investigated till now.

## How do you record plaque scores?

Plaque covering two-thirds or more of the crown of the tooth. The total score is then divided by the number of tooth surfaces, giving us the Turesky score. The Turesky score is then used to assess the patient’s oral hygiene using the table below.

Method.

0.0 – 1.0 Excellent oral hygiene
2.0 – upwards Poor oral hygiene

What is the difference between CPI and CPITN?

Abbreviations and acronyms: CPI = Community Periodontal Index; CPITN = Community Periodontal Index and Treatment Need; PVCH = Plenty Valley Community Health; WHO = World Health Organization.

What does a Russell periodontal index score of 6 indicates?

6 Gingivitis with pocket formation. The epithelial attachment is broken and there is a pocket. There is no interference with normal masticatory function; the tooth is firm in its socket and has not drifted. There is horizontal bone loss involving the entire alveolar crest, up to half of the length of the tooth root.

### What is a high plaque index?

A high plaque index and/or evidence of periodontal disease has been associated with presence of anaerobic bacteria in broncho-alveolar lavage (BAL) samples (Imsand et al., 2002).

What Vitamin Are you lacking when your gums bleed?

They found that low vitamin C levels in the bloodstream were associated with an increased risk for gum bleeding with gentle probing. The researchers also observed that increasing vitamin C intake may help resolve the problem.

What does BOS mean in dentistry?

BOS Dental Abbreviation. -1. BOS. British Orthodontic Society downvoted. Medical, Dentistry, Society.

## What is a plaque retention factor?

A number of local factors in the gingival environment act as site-specific problems which predispose towards the accumulation of plaque deposits and prevent their removal. These are called plaque retention factors (1). Accordingly the local plaque retentive factors (1) are tooth anatomic factors and iatrogenic factors.

What are index teeth?

Medical Definition of dental index

: a measure of the relative size of teeth that is obtained by finding the distance from the anterior surface of the first premolar tooth to the posterior surface of the last molar, dividing by the distance from the nasion to the basion, and multiplying by 100.

What is CPITN index teeth?

CPITN assesses the presence or absence of gingival bleeding on probing, supra or subgingival calculus and periodontal pockets by using a 0.5 mm ball tip WHO probe. Ten index teeth are examined, resulting in six scores determining the individual’s treatment needs (Ainamo et al., 1982; Dhingra &amp; Vandana, 2011).

### What is the periodontal disease index?

Contrary to Russell’s Periodontal Index, the Periodontal Disease Index was essentially a clinical tool that used a periodontal probe (66), with marks at 3, 6 and 8 mm, to measure the distance from the cemento–enamel junction to the bottom of the pocket (i.e. attachment loss) (64).

How do you determine severity of periodontal disease?

Severity is based on the amount of clinical attachment loss (CAL) and is designated as slight (1-2 mm CAL), moderate (3-4 mm CAL) or severe (> 5 mm CAL). Refractory periodontitis refers to continued attachment loss in spite of adequate treatment and proper oral hygiene.

What is the pocket depth of a tooth with a periodontal disease index score of 5?

On the other hand, scores of 4-6 are used to measure loss of periodontal attachment and are essentially irrevers- ible. A score of 4 is assigned if the loss of attachment is 3 mm or less, a score of 5 is assigned if the loss of attachment is greater than 3 mm but less than 6 mm.

## What is a low plaque score?

0 = no calcified plaque detected (risk of coronary artery disease is very low – less than 5%) 1-10 = calcium detected in extremely minimal levels (risk of coronary diseases is still low – less than 10%) 11-100 = mild levels of plaque detected with certainty (minimal narrowing of heart arteries is likely)
