Dental lasers are now being used in all fields of dental disciplines from oral surgery , restorative dentistry in caries removal and tooth preparation , cosmetic dentistry in soft tissue contouring and osseous crown lengthening to periodontology and endodontics in bacterial decontamination and associated surgical treatments. Most recently, researchers are looking into the application of lasers in implant dentistry and treatment of peri-implantitis.
Laser in Oral Surgery
Surgical procedures with the diode laser are often bloodless and pain free. These are very desirable attributes for both the dentist and patient.
1. Surgery General – the laser is working at its highest power level
2. Treatment of Abscess – A localized periapical or periodontal abscess
3. Apthous Ulcer Therapy
4. Hemostasis – bleeding following any dental surgery procedure.
5. Curettage – Treatment of advanced periodontal disease 6-10mm.
6. Epulides – Epulis Fissurata all biotypes from granulomatous to giant cell, and fibrous.
7. Irritation Fibroma – Fibromas of the tongue, lip, cheek, and gingiva.
9. Gingivectomy prior to impression or cad cam crown – excess tissue needing removal prior to crown impression, cosmetic recontouring.
10. Granuloma – granulomatous tissue present necessitating removal.
11. Hemangioma – hemangiomas of the lip cheek or tongue as well as blue or venous lake lesions
12. Removal of Hyperplastic tissue – any type of hyperplastic tissue.
13. Bacterial Reduction – any surface area needing reduction of bacteria.
14. Flap surgery – any area requiring a bloodless flap where compromised vascularity is not an issue, for example a split thickness flap for a connective tissue graft is not an area where the laser should be used.
15. Excisional biopsy – any tissue requiring removal that is indicated for a pathology report.
16. Retention cyst – any retained cystic tissue.
17. Exposure of Impacted Teeth – removal of impacted teeth or exposure for orthodontic purposes.
18. Edentulous ridge – removal of excess tissue for preprosthetic surgery.
19. Seeping hemorrhage – areas of persistent bleeding.
20. Sulcus preparation – preparing the sulcus for impressions for crowns or for cad cam images for crowns.
21. Verrucae Lesion – Removal of all Verrucae, wart like and papillomatous lesions.
22. Vestibuloplasty – Ill fitting dentures due to high muscle attachments.
23. Root end rescetion – Failed endodontic treatment needing endodontic surgery (apicoectomy/apicesectomy).
Laser for Gum Treatment
The diode wavelengths have desirable characteristics for periodontal therapy because of an excellent bacterial decontamination rate of 99.6%
1. Pocket treatment – periodontally generated pain
2. Gingivectomy – excessive gingiva, sufficient attached tissue and biologic width is needed.
3. Internal bevel incision – swollen gingiva, excessive pocket depth that will not resolve with conservative treatiment.
4. Bacterial reduction – mild to advanced periodontal disease accompanied by bleeding and or bone loss.
5. Decontaminate membranes – any surface which is in need of bacteial decontamination.
6. Open curettage – Pocket depth in excess of 7 mm where access and visualization of calculus for removal is
7. Pocket reduction – excessive pocket depth or a need to remodel the gingival architecture to a more favorable state where the attached gingiva is sufficient for removal, ie.the hard palate
Laser for Endodontic Treatment
Diode lasers provide excellent bacterial reduction in endodontic canals. The laser offers much better reduction than other means. Investigation of the dentinal tublii shows bacterial contamination up to 1,100μm in depth. Chemical decontamination produces activity up to only 100μm. Diode lasers will produce complete decontamination up to 1,000μm.
Laser for Teeth Whitening
A treatment which gets much more famous to every year in aesthetic dentistry is bleaching.
Laser in Dental Implant
Low Lever Laser Therapy
The therapy laser (LLLT – low level laser therapy) is a good instrument for a pain reduction, better wound healing and a bio-stimulation.
Special Laser Therapy – Depigmentation
Pigmented gums or lips can be treated with laser.
