Which dyes are used for caries detection?
Previous studies have shown that the caries detector dyes, basic fuchsin and acid red, lack specificity. Accordingly, their clinical use can lead to the unnecessary removal of sound tissue. In the present study, the specificity of three further dyes, Carbolan Green, Coomassie Blue and Lissamine Blue was studied.
What is the role of caries detection dye?
Although caries detection dyes are used to identify dentin infected with cariogenic bacteria, these dyes don’t stain the bacteria in the lesion. Rather, the propylene glycol penetrates areas of dentin with loose collagen fibers. This causes the caries detection solution to stain degraded collagen rather than bacteria.
What is the technique for using a caries detection device?
The most common method of caries detection is visual-tactile. Other non-invasive techniques for detection of early caries have been developed and investigated such as Quantitative Light-induced Fluorescence (QLF), DIAGNOdent (DD), Fibre-optic Transillumination (FOTI) and Electrical Conductance (EC).
Which film is used for caries detection?
The results of this study showed that the diagnostic performance of E- and F-speed films and direct digital radiography are similar for proximal caries detection.
How do you use carisolv?
With an instrument carry the Carisolv gel to the carious tooth; if required a handpeice may be used to open up the cavity. Wait for at least 30 seconds for the chemical process to soften caries till the gel appears cloudy. Scrape off the softened carious dentine. Keep the lesion soaked with gel and continue scraping.
What is the Periodontium?
The periodontium is a connective tissue consisting of four components: cementum, the periodontal ligament (PDL), alveolar bone, and gingival tissue.
How does a DIAGNOdent work?
How does DIAGNOdent work? DIAGNOdent consists of a pen-like probe which sends a safe and painless laser beam into the tooth to measure internal fluorescence. The laser, which operates at a specific wavelength (655 nm), and uses two-way optics to quantify the amount of light reflected back out of the tooth.
How is caries diagnosed?
Your dentist can usually detect tooth decay by:
- Asking about tooth pain and sensitivity.
- Examining your mouth and teeth.
- Probing your teeth with dental instruments to check for soft areas.
- Looking at dental X-rays, which can show the extent of cavities and decay.
What is a laser caries detector used to identify?
Laser Detection of Caries with DIAGNOdent Pen Diagnodent is a laser cavity detection device. It is a machine that uses near-infrared light (laser) to detect microscopic issues that occur in teeth and help detect tooth decay at the earliest stage and sooner than normal examination methods.
What is Qlf in dentistry?
Quantitative light-induced fluorescence (QLF™) is a new method for oral health assessment, providing additional visual information about caries and bacterial activity. This new method uses the principle of fluorescence for visual enhancement of caries detection and bacterial activity.
Are caries radiopaque or radiolucent?
The carious process results in demineralization, which is radiolucent, because the carious lesion attenuates the beam less than healthy tooth structure, resulting in more of the remnant beam reaching the film to produce more interaction in the emulsion layer, thus producing more black metallic silver.
What is carisolv gel?
Carisolv is a minimally invasive method for softening and removing dentine caries. A new, modified Carisolv gel has been developed in order to optimise the efficiency if its chemical caries dissolution.
How does the DIAGNOdent work?
What are the 4 components of the periodontium?
What are the types of periodontium?
Types of Periodontal Disease
- Types of Periodontal Disease.
- Gingivitis.
- Chronic Periodontal Disease.
- Aggressive Periodontal Disease.
- Periodontal Disease Relating to Systemic Conditions.
- Necrotizing Periodontal Disease.
How accurate is DIAGNOdent?
Diagnodent® accurately exposes more caries than X-rays and examinations. In fact, this revolutionary diagnostic tool is over 90% accurate.
How much does a DIAGNOdent cost?
$130 X 4 X 2 = The DIAGNOdent is a valuable device that can provide immediate return on investment in various ways. It will not only allow you to provide a higher level of patient care, but also enable the practice to detect more caries lesions than using traditional methods.
What is dental caries PDF?
DENTAL CARIES. DENTAL CARIES. Case Definition : Dental caries is an infectious microbiologic disease of the calcified tissues of the teeth, characterized by demineralization of the inorganic portion and destruction of the organic substance of the tooth.
How is caries risk calculated?
A comprehensive caries assessment should consider factors such as past and current caries experience, diet, fluoride exposure, presence of cariogenic bacteria, salivary status, general medical history, behavioral and physical factors, and medical and demographic characteristics that may affect caries development.
What are the different types of laser used in dentistry?
The dental lasers in common use today are Erbium, Nd:YAG, Diode, and CO2. Each type of laser has specific biological effects and procedures associated with them. A solid understanding of each of these categories of devices is imperative for any clinician hoping to pursue laser use in their practice.
