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 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. Further Reading: Ramfjord S. P. The Periodontal Disease Index (PDI).
What is the plaque index?
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.
What is index in dentistry?
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.How do you calculate gingival index?
The GI of the individual can be obtained by adding the values of each tooth and dividing by the number of teeth examined. The Gingival Index may be scored for all surfaces of all or selected teeth or for selected areas of all or selected teeth.
What is modified gingival index?
The Modified Gingival Index (MGI) uses a visual scale to assess gingival health. The MGI relies on a visual assessment of gingival changes to measure the severity of inflammation.
What is attached gingiva?
Attached gingiva – This tissue is adjacent to the free gingiva and is keratinized and firmly attached to the bone structure. It can range from 3-12 mm in height. Free gingiva – This tissue is not attached and forms a collar around the tooth.
Who developed the gingival index?
PMA Index (Schour and MassleV ~’) One of the first quantitative gingival indices is the PEDIATRIC DENTISTRY: Volume 3, Number 4 353 Page 2 P-M-A Index developed by Schour and Massler in 1944-1947, probably derived from the index suggested by King.What are the composite indexes?
A composite index is a statistical tool that groups together many different equities, securities, or indexes in order to create a representation of overall market or sector performance. Composite indexes are used to conduct investment analyses, measure economic trends, and forecast market activity.
What is 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).

How do you find the plaque index?
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.
How do you check periodontal index?
Periodontal Index for Treatment The maxillary sites are probed on the palatal side while the mandibular sites are probed on the buccal side, and scores are given from 0 to 3. The overall patient score (PIT score) is recorded as the highest score of the six test teeth.
How 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.
What is gingiva?
(JIN-jih-vuh) The tissue of the upper and lower jaws that surrounds the base of the teeth. Also called gums.
What is alveolar gingiva?
[jin-ji´vah, jin´jĭ-vah] (pl. gin´givae) (L.) the part of the oral mucosa covering the tooth-bearing border of the jaw; called also gum. … Called also alveolar gingiva. free gingiva the portion that surrounds the tooth and is not directly attached to the tooth surface.
What is alveolar crest?
The alveolar crest is the most cervical rim found in the alveolar bone proper. When it is healthy, the alveolar crest is slightly apical to the cementoenamel junction (CEJ) by about 1.5-2 mm. The alveolar crests of the adjacent teeth are also uniform in height along the jaw when they are healthy.
Which gingival index is non invasive?
Exceptional is the Modified Gingival Index (MGI) [8] which is completely noninvasive (i.e., exclusively visual).
How is gingivitis measured?
Measuring the pocket depth of the groove between your gums and your teeth by inserting a dental probe beside your tooth beneath your gum line, usually at several sites throughout your mouth. In a healthy mouth, the pocket depth is usually between 1 and 3 millimeters (mm).
Which is the use of a chisel scaler dental?
Chisels are great for dislodging large bridges of calculus in the interproximal areas (Figure 49). It also has a straight blade and a toe that has a bevel. This instrument is utilized with a push stroke typically between teeth.
What is the difference between composite index and covering index?
when we create index then we can mention multiple column name and that is called composite index but when we create cover index then we create index on one column and for cover index we mention other column in include function.
What is difference between composite index and single index?
Like a single index, a composite index is also a data structure of records sorted on something. But unlike a single index, that something is not a field, but a concatenation of multiple fields. position = ‘Top’; will have improved retrieval time, because the composite index is sorted by class-position .
How do compound indexes work?
How does composite index work? The columns used in composite indices are concatenated together, and those concatenated keys are stored in sorted order using a B+ Tree. When you perform a search, concatenation of your search keys is matched against those of the composite index.
Which kind of surgery is also known as flap surgery?
Flap surgery is a technique in plastic and reconstructive surgery where any type of tissue is lifted from a donor site and moved to a recipient site with an intact blood supply. This is distinct from a graft, which does not have an intact blood supply and therefore relies on growth of new blood vessels.
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.
What is pocket depth of a tooth?
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 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 are the types of index assessment of periodontal tissues?
This chapter addresses the more common periodontal indices for natural teeth and compares the following periodontal indices for dental implants: (1) longevity, (2) mobility versus rigid fixation, (3) percussion, (4) pain, (5) probing depths, (6) bleeding index, (7) crestal bone loss, (8) radiographic evaluation, (9) …
What is 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.
What is the difference between Dmfs and Dmft?
The DMF index has rules that apply to scoring an individual tooth or surface. Each tooth (DMFT) or surface (DMFS) may be counted only once, and decayed, even secondary caries, takes precedence over filled teeth/surfaces.
Who modified Dmft index?
Massier and Schour in 1952 -The progress of the dental caries in stages was modified and this caries severity index was developed . c. This index is used to measure the extent and depth of decayed surfaces and pulpal involvements based on clinical and radiographic examinations. 40.
