Dental plaque is a biofilm or mass of bacteria that grows on surfaces within the mouth. It is a sticky colorless deposit at first, but when it forms tartar, it is often brown or pale yellow. It is commonly found between the teeth, on the front of teeth, behind teeth, on chewing surfaces, along the gumline, or below the gumline cervical margins. Dental plaque is also known as microbial plaque, oral biofilm, dental biofilm, dental plaque biofilm or bacterial plaque biofilm. Bacterial plaque is one of the major causes for dental decay and gum disease.
Cryogenically enhanced intravascular interventions
InactiveUS6468297B1Less stenosisLowering indexCatheterSurgical instruments for coolingPercent Diameter StenosisPercutaneous angioplasty
Techniques and devices for treating atherosclerotic disease use controlled cryogenic cooling, often in combination with angioplasty and / or stenting. A combination cryogenic / angioplasty catheter may cool the diseased blood vessel before, during, and / or after dilation. Controlled cooling of the vessel wall reduces actual / observed hyperplasia as compared to conventional uncooled angioplasty. Similar reductions in restenosis may be provided for other primary treatments of the blood vessel, including directional arthrectomy, rotational arthrectomy, laser angioplasty, stenting, and the like. Cooling of vessel wall tissues will often be performed through plaque, and the cooling process will preferably take the thermodynamic effects of the plaque into account.

Pre-angioplasty serration of atherosclerotic plaque enabling low-pressure balloon angioplasty and avoidance of stenting
ActiveUS20100042121A1Large caliberSafely and accurately dilated and stretchedBalloon catheterCannulasPercutaneous angioplastyDrug eluting balloon
A device and method for intravascular treatment of atherosclerotic plaque prior to balloon angioplasty which microperforates the plaque with small sharp spikes acting as serrations for forming cleavage lines or planes in the plaque. The spikes may also be used to transport medication into the plaque. The plaque preparation treatment enables subsequent angioplasty to be performed at low balloon pressures of about 4 atmospheres or less, reduces dissections, and avoids injury to the arterial wall. The subsequent angioplasty may be performed with a drug-eluting balloon (DEB) or drug-coated balloon (DCB). The pre-angioplasty perforation procedure enables more drug to be absorbed during DEB or DCB angioplasty, and makes the need for a stent less likely. Alternatively, any local incidence of plaque dissection after balloon angioplasty may be treated by applying a thin, ring-shaped tack at the dissection site only, rather than applying a stent over the overall plaque site.

Minimal surface area contact device for holding plaque to blood vessel wall
A tack device for holding plaque against blood vessel walls in treating atherosclerotic occlusive disease is formed as a thin, annular band of durable, flexible material having a plurality of focal elevating elements on its outer annular periphery for holding loose plaque under a spring or other expansion force against a blood vessel wall. The focal elevating elements are designed to exert a holding force on a plaque position while minimizing the amount of material surface area in contact with the plaque or blood vessel wall and reducing the potential of friction with the intraluminal surface. This approach offers clinicians the ability to perform a minimally invasive post-angioplasty treatment and produce a stent-like result without using a stent.

A computer-implemented system and method of intra-oral analysis for measuring plaque removal is disclosed. The system includes hardware for real-time image acquisition and software to store the acquired images on a patient-by-patient basis. The system implements algorithms to segment teeth of interest from surrounding gum, and uses a real-time image-based morphing procedure to automatically overlay a grid onto each segmented tooth. Pattern recognition methods are used to classify plaque from surrounding gum and enamel, while ignoring glare effects due to the reflection of camera light and ambient light from enamel regions. The system integrates these components into a single software suite with an easy-to-use graphical user interface (GUI) that allows users to do an end-to-end run of a patient record, including tooth segmentation of all teeth, grid morphing of each segmented tooth, and plaque classification of each tooth image.

Method for treating periodontal disease
A method for treating periodontal disease in the periodontal pocket and for rendering the periodontal pocket resistant to future bacterial infection. After necrotic soft tissue and plaque is removed from the periodontal pocket by debridement, an optical fiber is inserted into the periodontal pocket. Laser emission is transmitted through the optical fiber into the periodontal pocket to substantially eradicate any remaining bacteria in the periodontal pocket and to also render the periodontal pocket resistant to subsequent bacterial infection. Optionally, the optical fiber is inserted into the periodontal pocket prior to debridement and laser radiation is transmitted through the optical fiber into the periodontal pocket and against both the soft and hard tissue. Such laser radiation not only kills bacteria in the periodontal pocket but also loosens the plaque which is typically present on the tooth and desensitizes the area surrounding the periodontal pocket.
