    • Agenda2  Introduction  Laser  Definition  History of Laser  Types of Laser  Applications of Laser in Dentistry  Hard Tissue  Soft Tissue  Other Applications  Case Studies Majd S. Hasanin May 29, 2009
    • Introduction3  Lasers have had an important impact on the practice of dentistry, especially for prosthodontics, restorative, and esthetic procedures.  Clinical applications continue to increase so that they can use lasers for treatments such as gingival and mucosal surgery, tooth preparation, osseous surgery, and photobiomodulation. Majd S. Hasanin May 29, 2009
    • Laser; Definition4  A laser is a device that emits light (electromagnetic radiation) through a process called stimulated emission. The term laser is anacronym for light amplification by stimulated emission of radiation.  Laser light is usually spatially coherent, which means that the light either is emitted in a narrow, low- divergence beam, or can be converted into one with the help of optical components such as lenses. Majd S. Hasanin May 29, 2009
    • Laser; History5  Around 1975, medical surgeons began using a new device that complemented and, in some cases, replaced the scalpel.  That instrument was a laser. During the 1980s, a carbon dioxide model was a common component in the operating suite. In 1989, the first laser specifically designed for dental use became available. Majd S. Hasanin May 29, 2009
    • Laser; Types6  Gas lasers  Chemical lasers  Excimer lasers  Solid-state lasers  Fiber-hosted lasers  Photonic crystal lasers  Semiconductor lasers  Dye lasers  Free electron lasers Majd S. Hasanin May 29, 2009
    • Laser; Types (based on wavelengths)7  Wavelengths can be categorized into three groups: ❶ Diode and Nd:YAG wavelengths target the pigments in soft tissue and pathogens such as Porphyromonas gingivalis, as well as inflammatory and vascularized tissue. ❷ Carbon dioxide lasers also easily interact with free water molecules in soft tissue, as well as vaporize the intracellular water of pathogens. Majd S. Hasanin May 29, 2009
    • Laser; Types8 ❸ Erbium lasers (Er,Cr:YSGG and Er:YAG) are sometimes called “all tissue” instruments because of their excellent absorption in both apatite crystals and the water of soft and hard tissue. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry9  What types of procedures can the laser do? For removing dental caries, old composite fillings, sterilizing infected root canals, bone shaping, apthous ulcer treatment, crown lengthening, apicoectomy, periodontal treatment and oral surgery. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry10  Hard Tissue (Tooth) Laser Dentistry Procedures: 1. Cavity Detector: Low intensity soft tissue dental lasers may be used for the early detection of cavities by providing a reading of the by-products produced by tooth decay. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry11 2. Dental Fillings/Tooth Preparation: Hard tissue dental lasers may eliminate the need for a local anesthetic injection and the traditional turbine dental drill. 3. Tooth Sensitivity: Dental lasers may be used to seal tubules (located on the root of the tooth) that are responsible for hot and cold tooth sensitivity. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry12 Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry13  Soft Tissue (Gum) Laser Dentistry Procedures: 4. Crown Lengthening: Dental lasers can reshape gum tissue (soft tissue laser) and bone (hard tissue laser) to expose healthier tooth structure. Referred to as crown lengthening, such reshaping provides a stronger foundation for the placement of restorations. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry14 5. Gummy Smile: Dental lasers can reshape gum tissue to expose healthy tooth structure and improve the appearance of a gummy smile. 6. Soft Tissue Folds (Epulis): Dental lasers may be used for the painless and suture-free removal of soft tissue folds often caused by ill-fitting dentures. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry15 7. Muscle Attachment (Frenula): A laser frenectomy is an ideal treatment option for children who are tongue tied (restricted or tight frenulum) and babies unable to breast feed adequately due to limited tongue movement. A laser frenectomy may also help to eliminate speech impediments. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry16  Other Laser Dentistry Applications: 8. Viewing Tooth and Gum Tissues: Optical Coherence Tomography is a safer way to see inside tooth and gums in real time. 9. Benign Tumors: Dental lasers may be used for the painless and suture-free removal of benign tumors from the gums, palate, sides of cheeks and lips. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry17 10. Cold Sores: Low intensity dental lasers reduce pain associated with cold sores and minimize healing time. 11. Nerve Regeneration: Photobiomodulation can be used to regenerate damaged nerves, blood vessels and scars. 12. Temporomandibular Joint Treatment: Dental lasers may be used to quickly reduce pain and inflammation of the temporomandibular jaw joint. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry18 13. Sleep Apnea: In cases where sleep apnea is a result of a tissue overgrowth in areas of the throat (which sometimes occurs with age), a laser assisted uvuloplasty or laser assisted uvula palatoplasty (LAUP) procedure can be performed to reshape the throat and relieve the correlating breathing problems associated with sleep apnea. Majd S. Hasanin May 29, 2009
    • Applications of Laser in Dentistry19 14. Laser whitening is superior to all other whitening techniques since:  laser whitening products contain the highest concentration of peroxide.  the laser provides the highest light intensity available.  the procedure is done in the office at chair-side. Majd S. Hasanin May 29, 2009
