Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) “Laser therapy ” Presented by Lopamudra Samantray Roll #EI Under the Guidance of Mr. Vivek Sharma

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) INTRODUCTION Laser means “light amplification my stimulated emission of radiation.” medical use of lasers is possible, when there is a favourable interaction between laser radiation and the human tissue. Laser therapy is successful in medical treatment like treatment of detached retina, neurosurgery, dermatology etc. user:

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Laser Principle During during laser tissue interaction, four optical process may occurs direct reflection at the boundaries of the layer. Scattering by molecules, particles, cell organelles and cells within the layer. Absorption or dissipation of absorbed energy. Direct transmission through the layer.

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Laser in Medical Applications Advantages of optical fibers in medical Consideration on fiber applications. Typical fiber application. Single mode fiber application.

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Application of Laser Treatment Laser, in medical, have wide applications under different specialties as listed below: *Opthalmology photo coagulation therapy. Photo distruption therapy. Fragmentation therapy. *Thoracic surgery. *Neurosurgery.

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Use of rubi laser in retinal treatment

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Laser therapy for teeth Most popular and result oriented lasers used dental treatment are *Ruby laser *Carbon dioxide laser *Neodymium laser

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Laser Physics The photons Light absorption Light amplification by stimulated emission of radiation

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Surgical technique of lasers The dental laser fall into fall into basic categies *Contact mode *Non contact mode either focused or defocused Non contact surgery requires siqnificantly greater power setting than contact surgery for the fiber optic delivered lasers to achieve the equivalent tissue effect.

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Rootcanal preparation and treatment Invitro root canal preparation The in-vitro root canal preparation was performed on freshly extracted human teeth that did not have any prior root canal treatment Invivo root canal treatment was performed on patients suffering from chronic apical peridontitis.

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Laser precautions in dentistry Following safety precautions must be heeded by practitioners when using laser are *Beam alignment *Laser control *Reflected energy *Fire protection *Eye protection *Anesthesia

Technical Seminar Presentation Presented by Lopamudra Samantray (#EI ) Conclusion Laser surface finds advantages because of following characteristic or properties *Highly sterile. *Non-contact surgery *Dry field, almost bloodless surgery * apparent reduction in post operative pain *More advantages for children since it is a painless surgery.
