Laser has created a unique place in modern dentistry through its mini-invasive interventions. Thanks to its characteristics, such as painlessness, minimal blood loss during surgical procedures, ability to sterilise the area while minimizing damage to the surrounding tissue, it’s getting more popularity in everyday dental practice.
Use of laser in dentistry is very wide, since it is for both hard and soft tissue applications.
Soft tissue application:
1. Wound healing – at low doses, laser application stimulates proliferation (reproduction and activity of cells). This controbutes to faster healing of lesions of recurrent aphthous stomatitis, or other mucositis and oropharyngeal ulcerations (often in patient undergoing radiotherapy for head and neck cancer).
2. Post herpetic neuralgia and apthous ulcer – low levels of laser energy can provide pain relief and accelerate healing. In recurrent herpes simplex labialis lesions, photostimulation during the prodromal (tingling) stage seems to arrest the lesions before painful vesicles form, accelerate the overall healing time, and decrease the frequency of recurrence.
3. Disinfection – laser can be applied effectively for killing bacteria in complex biofilms, which are typically resistant to the action of antimicrobial agents. Major clinical applications in dentistry include: disinfection of root canals, periodontal pockets, deep carious lesions, and sites of peri-implantitis.
4. Aesthetic gingival re-countouring and crown lengthening – laser enables the dentists to contour gingival margins of teeth to achieve higher aesthetic results.
5. Exposure of unerupted and partially erupted teeth – with laser use, the advante is of no bleeding, and moreover, it is not painful at all.
6. Removal of inflamed, hypertrophic tissue, gingivectomy
7. Frenectomies – laser assisted frenectomy is a simple procedure of removing a high or prominent labial and lingual frenulum. Frenectomies performed with lase permit excision of the frena painlessly, without bleeding and sutures.
Hard tissue applications:
1. Treatment of dental hypersensitivity – laser may decrease the hypersensitivity on cervically exposed hypersensitive dentine. The maintenance of a positive result is more prolonged that with other desensitizing agents.
1. Analgesic effect – laser can decrease the post-extraction pain and perception of pain after other oral surgeries, or pain following the root canal treatment.
2. Nerve repair and regeneration – the direct application of this technique has yielded positive recults in promoting the regeneration of inferior dental nerve tissue, damaged during surgical procedures.
