Thesis (M.Sc.) - Cairo University - National Institute of Laser Enhanced Science - Department of Laser Application in Oral Surgery

The aim of the present study is to assess the clinical value of the effect of the diode laser (980 nm) application in the treatment of the hyper pigmentation of the gingival. The used diode laser apparatus is an Italian system called quanta system laser and its model is (Quanta C) model, it is class 4 laser and need some precautions during using it. All the precautions of the laser protection must be followed by the operators. and the laser safety officer have to be available during the operation. All the operators and the audiences and the patient must wear the protective goggles of the suitable color for the used wave length. Group of fifteen patients males and females suffering from gingival hyperpigmentation in the anterior segment of the mouth with age range from 15-45 years old, and free from any systematic diseases which may affect on healing post operatively, will be included in this study. Patients will be selected randomly from the outpatient clinic of the oral and maxillofacial surgery department. Faculty of oral and dental medicine, Cairo university. And the operations was done in the out clinic of the national institute of enhanced laser science (NILES). Each patient asked to come for 3 follow up sessions after the operation in which swelling, wound healing, inflammation, will be assessed. First session 3 days after operation, second one will be 7 days after operation, and the third one will be 1 month later. And also patients will be assessed clinically by using digital photographs with the same camera and the same zoom. The recurrence rate will be assessed during the follow up appointments using the clinical evaluation score. All the patients showed no recurrence and the color of the ginigiva was turned to be pinky color. Finally, the diode 980 nm laser showed very rapid, safe, non painful and effective way for the treatment of the gingival hyper pigmentation. The study showed extra benefit for the diode 980 nm laser that it could a very effective way for the treatment of the gingival hyper sensitivity, but of course it need further study for the confirmation of this results
