Low-Level Laser Therapy in Treatment of Dentinal Hypersensitivity – A Systematic Review


SKU: 49011010, CFOX1695 Categories: ,


Dentinal hypersensitivity (DH) is an acute intensive tooth pain which can lead to severe discomfort during eating and drinking. Stimulating exposed dentinal tubules by either kind of thermal, tactile, chemical and/or osmotic stimuli is believed to be the cause of this pain
Home cures with desensitising toothpaste is often the first-choice treatment for DH due to its wide availability and convenience for patients. However, the effects of this treatment usually take 4 to 8 weeks to develop [ Patients suffering from severe DH who desire immediate relief are highly recommended to seek professional care. To date, a wide range of professional DH treatments has been introduced. The available modalities include varnishes and precipitants (e.g. fluorides, oxalates, calcium compounds, and bioactive glasses), restorative materials (e.g. adhesives, glass ionomers, and resins), agents for nerve desensitisation (such as potassium nitrates and guanethidine), light therapy, and periodontal surgery. It is hypothesized that dentinal tubules’ orifice occlusion (DOO) can help relieve such dental irritations Despite this wide range of treatment choices, there is no consensus on which professional treatment is most effective or which treatment-application technique is most efficient. Low-level light therapy (LLLT) refers to using red or near-infrared light to regulate biological activities without provoking thermal changes. It is valued for its noninvasiveness, safety, comfort, precision, reproducibility, and rapid action .
Thus, this systematic review was conducted to identify and evaluate literature regarding the effectiveness of laser application as a treatment modality by bridging a critical research gap and analyzing clinical evidence in the DH-alleviating efficacy of LLLT in comparison with placebo and other in-office desensitising strategies.
