Laser Phototherapy in Dentistry

Low level laser therapy has a range of useful applications for the dental and maxillofacial surgeon.

It can reduce post operative oedema and pain, and so the need for analgesics. Soft tissue lesions such as apthous ulcers and denture sores are ameliorated or resolved by photobiomodulation and herpes simplex lesions which are similarly treatable have also been shown to have their recurrence frequency reduced after treatment.

Photobiomodulation has also been demonstrated to improve bone formation, speed up implant integration and reduce the probability of dry socket. Production of secondary dentin in deep restorative situations is promoted by laser phototherapy and it can help with dentine hypersensitivity and reduce Pulp Hyperarmia.

Laser therapy can aid return of sensation after traumatic damage or severing of a nerve and is helpful for treatment of both trigeminal and post herpetic neuralgia.

"...dentists can expect to obtain better clinical results in their treatments or at least less clinical failure when LLLT is added to the conventional treatment by improving patient capability of wound healing. Use of LLLT provides better clinical outcomes, better acceptance by patients, and better professional recognition."
