LASERS IN DENTISTRY – By Dr.Manasa
HARD TISSUE LASERS : IMPROVING RESTORATIVE DENTAL TREATMENT
LiteTouch Er:YAG laser (AMD LASERS)
Patients often avoid dental care due to the fear of pain that they perceive they will feel either related to the local anesthetic injection or during drilling to remove caries.
Additionally, the vibration and sound associated with the dental handpiece during caries removal increases patient stress while in the chair for needed treatment. This may lead to treatment avoidance until the actual intraoral pain surpasses the feared pain of treatment. Providing a more comfortable experience for the patient aids in patients accepting and following through on dental care at an earlier stage.
A hard tissue laser allows the practitioner to remove carious tooth structure while preserving healthy enamel and dentin for truly minimal invasive dentistry. The more of the native tooth structure that can be preserved, the better the long-term prognosis

SOFT TISSUE LASERS :
Laser Soft-tissue Procedures
Soft-tissue lasers can be used for gingival contouring, leveling, troughing, gingivectomy, other periodontal procedures.Exposure of unerupted teeth, operculectomy, frenectomy, treatment of oral aphthous ulcers,soft-tissue incision, ablation and removal of soft-tissue lesions.
Laser gingival troughing also offers excellent hemostasis, and the removal of soft tissues such as fibromas or frenulae can be easily accomplished with minimal collateral damage, again with excellent hemostasis.
Diode lasers (i.e. Picasso, AMD LASERS, Indianapolis, IN) are designed for soft tissue applications. These allow the practitioner to remove gingival tissue to expose root caries, esthetically recontour gingival tissues, to treat periodontal pockets and a range of other applications that present daily in the typical practice.
FRENECTOMY DONE USING SOFT TISSUE LASERS
Advantages of lasers in dentistry :
- Excellent hemostasis
- Good visibility with pen-style holder
- Efficient and effective soft-tissue removal
- Safe around implants
- Typically requires no/topical anesthesia
- No periodontal pack or suturing is required
- Reduced post-operative pain
- Reduced gingival recession following margin exposure
- Reduced swelling and discomfort.
