A posterior scaler shown in relation to a posterior tooth on a typodont. Periodontal scalers are dental instruments used in the prophylactic and periodontal care of teeth (most often human teeth), including scaling and root planing. The working ends come in a variety of shapes and sizes, but they are always narrow at the tip, so as to allow for ...
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 ...
In dentistry, debridement refers to the removal by dental cleaning of accumulations of plaque and calculus (tartar) in order to maintain dental health. [1] Debridement may be performed using ultrasonic instruments, which fracture the calculus, thereby facilitating its removal, as well as hand tools, including periodontal scaler and curettes, or through the use of chemicals such as hydrogen ...
The magnetostrictive power scaler vibration is elliptical, activating all sides of the tip, whereas the piezoelectric vibration is linear and is more active on the two sides of the tip. [39] Special tips for ultrasonic scalers are designed to address different areas of the mouth and varying amounts of calculus buildup.
The periodontal curette is a type of hand-activated instrument used in dentistry and dental hygiene for the purpose of scaling and root planing. [1] The periodontal curette is considered a treatment instrument and is classified into two main categories: universal curettes and Gracey curettes. [ 1 ]
As of 2013, periodontal disease accounted for 70.8% of teeth lost in patients with the disease in South Korea. [12] Periodontal disease is the second most common cause of tooth loss (second to dental caries) in Scotland. [13] Twice-daily brushing and flossing are a way to help prevent periodontal diseases. [14]
Chronic periodontitis is initiated by Gram-negative tooth-associated microbial biofilms that elicit a host response, which results in bone and soft tissue destruction. In response to endotoxin derived from periodontal pathogens, several osteoclast-related mediators target the destruction of alveolar bone and supporting connective tissue such as the periodontal ligament.
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.
