Periodontology or periodontics (from Ancient Greek περί, perí – 'around'; and ὀδούς, odoús – 'tooth', genitive ὀδόντος, odóntos) is the specialty of dentistry that studies supporting structures of teeth, as well as diseases and conditions that affect them.
A report by World Health Organization in 1978 led to the creation of the Community Periodontal Index of Treatment Needs (CPITN) and a periodontal probe termed WHO 621 ("Trintity"). It has a ball end of diameter 0.5 mm and a first colored band at 3.5 - 5.5 mm. Another colored band at 8.5 - 11.5 mm may be present.
Periodontal charting refers to a chart utilized by a dental care professional (periodontist, dentist, registered dental hygienist) to write and record gingival [1] and overall oral conditions relating to oral and periodontal health or disease.
Scaling and root planing, also known as conventional periodontal therapy, non-surgical periodontal therapy or deep cleaning, is a procedure involving removal of dental plaque and calculus (scaling or debridement) and then smoothing, or planing, of the (exposed) surfaces of the roots, removing cementum or dentine that is impregnated with calculus, toxins, or microorganisms, [1] the agents that ...
The periodontal ligament depends on stimulation provided by function to preserve its structure. Within physiologic limits the PDL can accommodate increased function by increasing its width. Forces that exceed the adaptive capacity of the periodontium produce injury called trauma from occlusion. When occlusal forces are reduced the PDL atrophies ...
In periodontal health, gingival diseases and conditions, there are 3 sub-types: [5] I) Periodontal health and gingival health Gingival health on an intact periodontium Gingival health on a reduced periodontium i.Stable periodontitis patient ii.Non periodontitis patient. II) Gingivitis - dental biofilm induced Associated with the dental biofilm ...
Periodontal pathology, also termed gum diseases or periodontal diseases, are diseases involving the periodontium (the tooth supporting structures, i.e. the gums). The periodontium is composed of alveolar bone , periodontal ligament , cementum and gingiva .
When a tooth has very deep periodontal pockets it may not be possible to fully remove the dental plaque/tartar/calculus from the tooth's root surface with scaling alone. In open flap debridement (OFD) the gum is peeled back to make it possible for the dentist to see and ensure full removal of tartar/calculus from these difficult to access areas ...
