About

Dentin hypersensitivity (DH) is a common clinical problem frequently seen in dental patients. According to Splieth et al., the prevalence of dentin hypersensitivity is 3-98% in adult population.DH is described as a short, sharp pain or discomfort that responses to certain stimuli, typically thermal, tactile, osmotic or chemical, due to exposed dentinal surface which can be explained by the hydrodynamic theory.

The laser is a narrow, focused beam of light emitted to vaporise, fuse, melt, or seal dentinal tubules using laser heat to induce hydroxyapatite crystals for recrystallisation of the mineral component of dentine. The obliteration of dentinal tubules is caused by heat generated by laser beam which inhibits the transmission of the stimulus in the dentinal tubules.

Grape seed extract contains proanthocyanidins (PA) which is able to bind to proline-rich proteins, like collagen, and contributes in enzyme proline hydroxylase activity that is essential for the biosynthesis of collagen in the dentin. The cross-linking action of collagen fibrils in dentin also able to prevent mineral loss.

Interventional model: Parallel Assignment

Masking: Triple Blind

---

30 participants in 3 patient groups

Grape seed extract

Experimental group

Description:

grape seed extract with 95% proanthocyanins will be applied topically to the hypersensitive dentin area for 10 minutes, followed by rinsing with water.

Treatment:

Drug: Grape Seed Extract

Low-level laser therapy

Experimental group

Description:

The low-level laser diode treatment of 810 nm will be performed using a commercially available diode laser device. The device will be set at a wavelength of 810 nm, with a power output of 0.5 watts tip of diameter 300 μ in non-contact mode starting at a distance of 5-6 mm away from the hypersensitive tooth area and slowly approaching within a distance of 2-3mm in a scanning motion covering the entire hypersensitive tooth area for a period of 30 seconds to 1 minute.

Treatment:

Device: Low-level laser therapy

Combination of low-level laser therapy and grape seed extract

Experimental group

Description:

Grape seed extract will be applied topically to the hypersensitive dentin area for 10 minutes, followed by low-level laser diode treatment.

Treatment:

Drug: Grape Seed Extract

Device: Low-level laser therapy
