CPP-ACPF and Laser's Effect on Dentin Hypersensitivity

2018-11-27 21:42:14 | BioPortfolio

Summary

The aim of this study was to evaluate the effect of casein phosphopeptide amorphous calcium phosphate fluoride paste (CPP-ACPF) associated with low level laser therapy (LLLT) in the symptomatology and on the quality of life of the individuals with dentin hypersensitivity in a randomized placebo-controlled clinical trial. Volunteers 18 to 50 years old with hypersensitive teeth were randomized into 4 groups: GPlacebo - positioning of the laser tip without light emission + placebo dentifrice; GCPPACPF - positioning of the laser tip without light emission + CPP-ACPF application; GLaser - laser tip positioning with light emission + placebo dentifrice; GLaserCPPACPF - positioning and light emission of the laser beam + CPP-ACPF.

Description

GLaser received the laser application using the infrared light spectrum with wavelength of 808 nm with its active AsGaAl medium in two points of the vestibular face of the hypersensitive teeth. At each point it was applied 60 J / cm², for 16 seconds. Three laser's sessions were applied with a time interval of 24 hours between them. GLaserCPPACPF first received the CPPACPF application and then the laser application according to the manufacturer's recommendations. Before initiating laser therapy, the equipment was calibrated with a tester (MMOptics Ltda®, Brazil).

The GCPPACPF volunteers were submitted to the application of the CPPACPF'S containing tooth paste MI Paste Plus™ (Recaldent™, GC América, USA) on the vestibular surfaces of hypersensitive teeth with the aid of a microbrush applicator (Microbrush, 3M ESPE, Brazil) for 05 minutes. Then, a rubber cup (Unid Microdont, Brazil) mounted on a low speed handpiece (500, Kavo, Germany) was used to scrub the desensitizing gel during 20 seconds on each tooth, according to the manufacturer's specifications. GPlacebo followed the same protocol used in GCPPACPF. In addition to the desensitizing treatments, all GCPPACPF and GPlacebo volunteers received the positioning of the laser tip to mimic the light emission produced in GLaser and GLaserCPPACPF. The noise emitted by the laser device was mimic through the sound reproduction of a smartphone application (HD Voice Recorder - iPhone 6s, Apple®, USA).

Medical and Biotech [MESH] Definitions

Pain associated with exposed DENTIN surfaces of the teeth.

A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).

Adherent debris produced when cutting the enamel or dentin in cavity preparation. It is about 1 micron thick and its composition reflects the underlying dentin, although different quantities and qualities of smear layer can be produced by the various instrumentation techniques. Its function is presumed to be protective, as it lowers dentin permeability. However, it masks the underlying dentin and interferes with attempts to bond dental material to the dentin.

An apparently hereditary disorder of dentin formation, marked by a normal appearance of coronal dentin associated with pulpal obliteration, faulty root formation, and a tendency for peripheral lesions without obvious cause. (From Dorland, 27th ed)

Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
