ABSTRACT
Introduction: Intraoral Soft Tissue Esthetics Has Become A Significant Aspect Of Dentistry And Clinicians Are Faced With Achieving Acceptable Gingival Esthetics As Well As Addressing Biologic And Functional Problems.
Aim Of Study: Was To Evaluate The Effect Of Diode Laser Irradiation On Gingival Depigmentation.
Materials and Methods: 3 Watts Continuous Mode Diode Laser Was Used To Remove Gingival Hyperpigmentation Of Dogs. Specimens Were Divided According To The Follow Up Periods Of (1, 2, 4 And 8 Weeks) Where The Experimental Specimens Were Contralateral To The Control Ones. Specimens Were Evaluated Pre- And Post-treatment Histologically Using H&E And Ultrastructurally By Transmission Electron Microscope.
Results: Histological And Ultrastructural Evaluation Revealed A Decrease In Melanin Content In The Follow Up Periods Compared To The Baseline. Meanwhile, The Recurrence Of Melanin Was Observed More In Groups Of 4 And 8 Weeks After Laser Irradiation Yet Did Not Reach The Baseline.
