Evaluation the Effect of 805 nm Wavelength Diode Laser on Repair of Mandibular Bone Repair and Skin Incisions in Rabbits
...Show More Authors

The long healing time of bone after tooth extraction in order to construct artificial teeth is uncomfortable to the patient because of aesthetic or masticatory problems in addition to the daily visit to dental clinic. The objective of this study was to evaluate the effect of 805 nm diode laser with long time intervals on repair of bone and skin incisions in rabbits through biochemical, radiological and histological findings. Eighteen New-Zealand rabbits were undergone surgical operations to make a cavity in the bone of the lower jaw, the rabbits were divided into two groups:- Group A (control group) containing nine rabbits. Group B (lased group) containing nine rabbits in which two cavities were done, one on the right side and the other on the left side of the mandible. The cavities were subdivided into two groups according to the exposure time. Group B1 (the right side) which was underwent treatment with 805 nm continuous diode laser with output power of 900mW and exposure time of 5 min, every 72 h for two weeks. Group B2 (the left side) which was underwent treatment with 805 nm continuous diode laser with output power of 900mW and exposure time of 10 min, every 72 h for two weeks. The diode laser with a wavelength of 805 nm, power 900 mW and operating on continuous mode was applied directly over the site of the cavity according to the group. Radiological findings, histological and biochemical evaluations for both bone and skin were done for all groups after 7, 14 and 28 days of follow up. The histological results showed that there was a complete wound healing and bone repair at day 28 postoperatively in sub group B2 which is represented by the group treated with 805 nm diode laser with exposure time of 10 min, every 72 hours. In conclusion, the 805 nm continuous wave diode laser with power density of 1.79 W/cm2 and exposure time of 10 min, every 72 h for two weeks was beneficial to stimulate healing in bone and skin.

TREATMENT OF SYMPTOMATIC CERVICAL ECTOPY USING CO2 LASER (10600 nm) – Case Study
...Show More Authors

Background: Cervical ectopy advanced to erosion is one of the common conditions in gynecological and pathological study. It is considered as a physiologic condition resulting from columnar epithelium migration from the cervical canal into the vaginal portion of the cervix, in which no treatment for asymptomatic cervical ectropion can be given. Treatment can be accomplished via thermal cauterization (Electro cautery), Cryosurgery. CO2 laser therapy is another modality of treatment.

Objective: To study the effectiveness of CO2 laser therapy and evaluate it as a biomedical tool for the treatment of cervical ectropion. The study was done at Laser Medicine Research Clinic at the

Treatment of Skin Scar Using CO2 Laser with or Without Corticosteroid
...Show More Authors

CO2 Laser (10600nm) is the recent method in the management of challenging skin scar resulting from trauma, burn and surgical wound. The aim of this study was to evaluate the efficacy & safety of fractional CO2 laser (10600nm) in treatment of skin scar. Materials and Methods:Twenty patients with different types of scars treated with fractional CO2 (10600nm) laser, (10 patients) were given additional intralesional Triamcinolone. Results: All of the twenty patients included in this study showed some sort of improvements in scar texture, height and pliability and all of the ten patients who received intralesional Triamcinolone after laser show complete satisfaction. Conclusion:Fractional CO2 (10600nm) laser can be used as alternative, ef

Intraoral Repair of Dental Ceramics Using Er,Cr:YSGG Laser: Review
...Show More Authors

Introduction: All-ceramic crowns are widely used in prosthodontics and cosmetic dentistry due to their good esthetic and proper physical properties. Chipping of ceramic is one of the most common post-insertion complications, that can be fixed either extraoral or intraorally. The latter is time time-effective alternative, less traumatic, and low-cost. A newer objective method of laser is a surface modification of ceramics to increase surface roughness. The aim of this study is to provide a review of Er,Cr;YSGG (2960nm) in intraoral repair and shear bond strength (SBS).

Design and Operation of Mini-TEA CO2 Laser and Investigation of Preionization Effect
...Show More Authors

A Mini-TEA CO2 laser system was designed and operated to obtain a pulse at 10.6 μm. Output energy of 30 mJ, with preionization pins, and pulse duration of 100ns were obtained. While an output energy of 6mJ and pulse duration of 100 ns in absence of pre-ionization were obtained. The system was operated with Ernest profile main-discharge electrodes. Dependencies of supply voltage and output laser energy on the pressure inside laser cavity were investigated as well as dependencies of supply voltage and output energy on the main capacitor(8CO2 : 8N2 : 82He :2CO). Efficiency of was calculated to be 4.4%.
