Laser become an important part in cosmetic dentistry it provide predictable healing and reduce postoperative pain and swelling All information also in my youtube account https://www.youtube.com/watch?v=YqbWfA9jhWE&t=428s

3. What the meaning of gingivectomy?
Gingivectomy:- Is the surgical procedure for removing the gum tissue it is
necessary when the gums have pulled a way creating deep pocket

4. Conventional Surgical Technique

8. Advantage of laser against conventional technique

10. Disadvantages
 Laser irradiation
 The cost and the size of laser device
 All lasers require specialized training and attention to safety

11. Types of lasers use in gingivectomy
 Diode laser (800-980nm)
 Nd:YAG laser (1064nm)
 Co2 laser (10600nm)
 Er:YAG laser (2940nm)
 ErCR:YSGG (2780nm)

15. Crown lengthening
Is the surgical procedure used to gain the access to subgingival carries, ,
expose margin and explore fracture

16. Conventional technique

17. Types of lasers used in crown lengthening
 The diode, Nd:YAG and CO2 lasers are sufficient if the objective soft
tissue
 If the objective is osseous structures the erbium lasers are used

24. Muccogingival surgery
They are surgical procedures designed to correct defect in the morphology,
position or amount of gingiva

26. Esthetic Treatment Of Gingival Hyperpigmentation
Oral pigmentation:- is the discoloration of the oral mucosa or gingiva due
to variety of conditions and is associated with endogenous and exogenous
factors

27. The Causes of oral pigmentation
Most of pigmentation is caused by five primary pigments these include:-
 Melanin
 Melanoid
 Reduced haemoglobin
 carotene
 Bilirubin
 Iron

28. Conventional technique of gingival depigmentation

35. Frenectomy
Is the complete removal of the frenum including its attachment to the
underlying bone

36. Conventional surgical technique

37. The Types of Lasers Used In Frenectomy
 All laser WL can be used successfully
 CO2 and Nd:YAG lasers are less post operative pain and less
complication than scalpel teghnique
 The depth of penetration of Diode and ND:YAG more than Erbium and
Co2

43. Laser Frenectomy

46. Bleaching
Is defined as the lightening of the color of the tooth through the
application of a chemical agent to oxidize the organic pigmentation in the
tooth

49. Type of Lasers Used In Bleaching
 Erbium lasers, Diode laser and Co2 lase are all used in dental bleaching
 Erbium lasers heat the gel, Diode heat all the tooth

51.  Diode laser ( 810-830nm) :- in order to
decrease its thermal effect in bleaching
process it should be used
 At minimal power

53.  Erbium laser doesn’t penetrate through the gel it
minimize thermal damage

57. Removing veneer by laser
