Dentin hypersensitivity (DH) is a fairly common and painful dental condition. It is described as pain that results from exposed dentine, usually in response to thermal, chemical, tactile, or osmotic stimuli. Reports suggest that between 4 and 74% of people have this issue, suggesting that it is a prevalent issue.
Dentinal hypersensitivity associated pain is one of the important factor which elicit oral discomfort and restricts the patients to perform oral hygiene and or interfere with dietary intake; thereby may cause periodontal diseases, nutritional deficiency etc. There are many different therapy options available (medicated dentifrices, oral rinse, restoration etc,) which required continuous usage as none is capable of constant delivery of the agent to the site, but are associated with certain limitations e.g. lack of patients compliance, poor taste, time consuming etc.
Consequently, an effective substitute method for treating dental hypersensitivity right away is laser desensitization. Dentin hypersensitivity was initially treated with lasers in 1985. According to research, when a laser interacts with dental pulp, it has a photo bio modulating effect that increases odontoblasts' metabolic activity and plugs the dentinal tubules by encouraging the production of tertiary dentine, which eventually lessens hypersensitivity.
This case report shows the successful management of hypersensitivity of dentin in patient’s teeth affected by erosion by using a diode laser (980 nm wavelength, 1W power) in multiple appointments followed by restorative rehabilitation.
