Laser technology provides several benefits for prosthodontic and implant dentistry procedures. Lasers allow for precise soft and hard tissue incisions, coagulation to control bleeding, and reduction of postoperative pain and swelling. The erbium family of lasers can be used for soft tissue procedures as well as bone removal or contouring. This makes lasers useful for denture support surgery like vestibuloplasty and tuberosity reduction. Lasers also aid in second stage implant surgery by providing a dry, clean surgical site for immediate impressions. While many lasers can be used, erbium and carbon dioxide lasers interact minimally with dental implants.
Semiconductor lasers operate based on stimulated emission of radiation from a semiconductor material. When a semiconductor is forward biased, electrons from the n-type region combine with holes in the p-type region and release energy in the form of photons. These photons stimulate additional electrons to release photons of the same frequency, resulting in coherent laser emission. Semiconductor lasers can be homojunction lasers made of the same semiconductor material on both sides or heterojunction lasers made of different materials on each side. They have applications in optical storage, laser printing, barcode scanners, and fiber optic communication due to their small size, efficiency and ability to be integrated with other devices.

Protocol of Dental Treatment in Radiotherapy Indicated Patients.pptxHoor-E-Jannath Prity
The dental management of patients who are to or have received radiotherapy pose a great challenge for general dentists. It is very important that we adhere to the established treatment regime to avoid any complications that may occur because of unplanned dental treatments.
1. Laser treatment can be used for face rejuvenation through either ablative or non-ablative procedures. Ablative procedures completely remove the epidermis and damage the dermis, resulting in more dramatic effects but longer recovery times. Non-ablative procedures heat the dermis without damaging the epidermis, providing more subtle effects with little to no downtime.
2. Proper patient evaluation and expectations are important to determine whether ablative or non-ablative treatment is appropriate. Non-ablative treatments require multiple sessions to achieve results gradually over time with minimal risks, making them better for some skin types and goals. Ablative treatments carry higher risks like scarring and pigmentation changes.
Laser therapy allows for less pain, swelling, and scarring than traditional surgery through its biostimulative effects and modulation of the inflammatory response. It has a variety of applications including wound healing, pain management, and post-operative care. Proper dosage, wavelength, power, and application technique are important factors to achieve therapeutic benefits while avoiding tissue damage.
Postoperative spinal infections can occur after both instrumented and non-instrumented spinal procedures. Risk factors include obesity, malnutrition, diabetes, smoking, surgical complexity, blood loss over 1L, and revision surgery. Superficial infections present with erythema and drainage while deep infections cause pain, fever, and neurological deficits. Evaluation includes labs like ESR, CRP, and blood/wound cultures as well as imaging like MRI, CT, or bone scan. Common pathogens are Staphylococcus and MRSA. Treatment involves antibiotics targeted to culture results as well as surgical debridement of infected tissues.

Radiotherapy is used in the management of oral cancer for curative and palliative purposes. It can be delivered as primary treatment combined with chemotherapy for organ preservation or after surgery as adjuvant treatment. Newer radiotherapy techniques like IMRT allow higher doses to be delivered to tumors while reducing damage to nearby organs. Side effects depend on treatment dose and area irradiated, and may include mucositis, xerostomia, skin changes, osteoradionecrosis and rare complications like carotid rupture. Ongoing research aims to reduce toxicity through altered fractionation schedules and novel delivery methods.

7. 1965 Gold used Ruby and CO2 Lasers
1970’s CO2 and Nd:YAG tooth Prep
1980’s Emphasis switched to incision
of soft tissue with CO2
1990’s Introduction of Diode and
Er:YAG and pulsed Nd:YAG
7
8. Diode – 810, 940, 980 nm
Nd:YAG – 1064 nm
Er:YAG – 2780 nm
CO2 – 10,000 nm
A Nanometer (nm) equals 10 to the -9th Power
8
10. Stimulated Emission
• Atoms of the active medium
are stimulated to a higher
energy level
• This energy is released as a
photon as the atom returns to
a more stable energy level
• Released photons can go on to
stimulate more atoms in the
crystal thus producing more
photons (Amplification)
Single Photon Enters Atom
Two Photos Exit Atom
External Stimulus

17. Laser Mediums – Gas, Liquid or Solid
Medium determines Wavelength (Frequency)
Wavelength Absorbed Differently by H2O and Tissue
Absorption Depth Determined by Wavelength
Pulse and Duration focus and concentrate Energy
17
19. Continuous emission of laser energy will non-selectively
ablate tissue
Pulsed Energy increases Wattage to area and reduces
Duty Cycle (time laser on) by ½
Generally Nd:YAG runs 0.2% of time. This reduces
thermal effects on tissue
Varying the Pulse Duration can provide additional
benefits such as ablating tissue and hemostasis
19
22. Absorption Affects infected tissue
**** Most Important Affect***
Reflection: Dissipates quickly
Scattering: May Harm Surrounding Tissue
Transmission May Harm Surrounding Tissue
Hemostasis Blood Coagulation
22

31. Effects of Exposure Duration
The Zone of Necrosis is the area of tissue affected by the laser’s energy and heat.
***The Diode laser’s Zone of Necrosis is smaller than
that of other Electro-Surgical Devices.***
The Zone of Necrosis is affected
by the length of exposure
and the power
Setting of the Laser.
31
34. Increase patient comfort
Increase effectiveness of treatment
Improve patient acceptance of care
Increase reparative and regenerative healing
Increase types of procedures available

Benefits of Laser Treatment
34
35. High Bactericidal effect
Reduce Post-op Inflammation & Edema
Increased productivity – Less wait time
Greater Hemostasis
Minimal wound contraction – skin shrinkage
Retard epithelial proliferation apically along healing
root surface to enhance periodontal tissue regeneration
Reduce Noise factor
35
36. Laser irradiation can interact with tissues even in the
non-activated mode. Meaning laser beams can reach
the client’s eye and other tissues surrounding the target
in the oral cavity
You need specific eyewear according to wavelength for
client and clinician
Cost and size will constitute an obstacle for clinical
application in Dental Hygiene.
36
37. Patients on Blood Thinners are not required to stop
medication… Why?
High BP – Epinephrine is contraindicated
Client allergic or hypersensitive to Epinephrine.
37
38. Dental lasers can NOT be implemented in the
following clients.
Patient suffers from a skin disease, and is allergic to
light
38
40. Glasses
Each laser must have several pairs of protective
eyewear related to its wavelength. You and your
patient MUST wear protective eyewear to avoid any
possible retinal damage.
Signage
It is recommended that signs are posted in the
cubicle where laser therapy will be performed. Make
sure other employees know not to enter when the sign
is posted.
40
42. 200 Million US Adults and nearly 95% have some form
of Periodontal disease with 30% having Moderate to
Severe Periodontitis
Only 3% of the Moderate to Severe actually get
treatment!
When Detected and Treated Early this Disease Does not
have to be as Destructive regarding, Function,
Phonetics, Esthetics or Systemic Implications!
42
46. • Surgical manipulation of tissue with consequences
• Increased sensitivity and risk of root decay
• Cost of Procedure
• Fear of Surgical Procedure
• Must have Patients Cleared of Any Medical Issues
i.e. clotting concerns
46
47. • Recession
• Sensitivity
• Morbidity
• Cost
• Long Junctional
Epithelium Loss
Consequences of
Traditional Therapy:
47
48. Periodontal Disease Manifests Clinically as Red Inflamed Tissue.
The Disease is initiated by Anaerobic Bacteria
that invade tissue and cementum
Porphyromonas Gingivalis
Tannerella forsythia
Mutans streptococci
Streptococcus mutans
Streptococcus sobrinus
Streptococcus Intermedius
Prevotella intermedia
Treponema denticola
Lactobacilli
Aggregatibacter actinomycetemcomitans
48
49. Ultrasonic debridement results in a smooth surface which
still contains debris, bacteria, contaminated root cementum
and sub-gingival plaque.
Laser Treatment roughens the root surface enhancing
adhesion of fibroblasts…
Leads to greater periodontal attachment
Laser treatment initially blocks the growth of epithelium
which in effect enhances periodontal attachment.
49
50. Uses heat to “Melt” Tissue
Excellent for Hemostasis and effective clotting
Can penetrate 2 – 3 mm in depth
ONLY indicated for soft tissue applications
Electromagnetic energy from the laser beam is absorbed
by the carbonized tip. The molecules in the tip are
converted to heat energy, then the tip emits visible
infrared light.
Has been shown to regenerate cementum
50
52. Want to Destroy Quantity and Quality of Bacteria
Want to De-Epithelialize (Infected tissue)
Want to Penetrate into cementum and gingival
tissue
Want to Minimize damage to healthy tissue
Want to Stimulate Regeneration 52
53. • Laser irradiated surfaces removed bacteria from
biofilm and hard surfaces
• Abrupt decrease in bacterial ATP = cell mortality
• Effective bacterial ablation and slower rate of
recolonization
• 55% bacterial reduction from laser alone,
independent of heat or wavelength
53
54. Addresses all Treatment Objectives
Better Decontamination of Pocket
Bio-Stimulatory and Regenerative
Shorter Treatment - weeks vs. months or years
Less Invasive and Lower risk than Surgery
Not Necessary to Go Off Anti-Coagulants
Better Patient compliance
54
55. Laser Function
The laser functions in such a way that it can cut
or affect soft tissue and cut it with precision.
It can Coagulate blood in the treatment area
It can reduce Post-op inflammation and edema
These area all desired effects of Laser Treatment.
55
