#LaserDentistry is carried out with an instrument that produces a very narrow, intense beam of light energy. When the beam of laser light reaches the jaw tissue it causes a reaction. The effects could be the light the produced by the laser can remove or shape tissue.Laser treatment can be said as safe and effective treatment for a wide range of dental procedure.

1. APPLICATIONS OF LASERS IN CLINICAL DENTISTRY
Dr. Sachdeva’s Dental Aesthetic And Implant Institute I 101, Ashok Vihar Phase 1, Delhi- 110052

2.  Lasers in preventive dentistry
• Laser treatment is becoming widely recognised and can be applied to prevent caries from
developing and to reduce the progression of caries.
• The mechanism of laser should be understood before a dentist could apply in his daily practice.
• During laser treatment, moderate heat(co2 laser produces temp > 1000 degree Celsius) is
produced which changes the composition of enamel from ‘hydroxyapatite’ to ‘carbonated apetite’
in which there is loss of water in the crystals, as a result the pores of enamel shrink down to form
‘microspace system’. The microspace system provides a means for trapping calcium, phosphate
and fluoride ions which release during demineralization and acts as site for re-precipitation.

3. • The trapped minerals phases inside the Enamel and impedes lesion
formation and progression causing enhanced resistance against
demineralization.
• As the microspaces are smaller in size, it decreases the permeability of the
Enamel thereby reducing the diffusion of ions in and out thereby reducing
the demineralization process. Thus a seal is achieved and so is resistance to
caries.
• The Dentin also gets acid resistance as there is increased mineral content
due to burning of organic matter from tissue so there is increased Calcium
and Phosphate found in recrystallized Dentin.
• It is a very effective tool for disinfecting the root canal after mechanical
root canal treatment as it has sufficient penetration depth.

4. LASERS IN ENDODONTICS
• Endodontic procedure carried out by conventional methods
may not be successful in spite of utmost care.
• Despite the mechanical removal, irrigation and disinfection
of canals, the bacteria can still persist which cannot be
reached by conventional techniques.
• As the technology has advanced, now lasers are used in
endodontic procedures to improve the prognosis of the
treatment of tooth.
• Laser light penetrates upto >1000 micrometre into the
dentin and provides a distinct advantage since the bacteria
can immigrate upto 1000 micrometer into tubules.

5. • It is a very effective tool for disinfecting the root canal after mechanical root canal
treatment as it has sufficient penetration depth.
• It is effective in curved canals also and the energy is transported by thin flexible
fibres which have diameter of only 200 micrometre.
• Laser eradicates the microbial flora of root canal and also has same effect on
surrounding dentin without affecting the surrounding tissue and has good
disinfection mechanism without causing pain and improving the prognosis of
the endodontic treatment.
• When in contact with laser, cell membrane gets destroyed due to the impact of
direct heat and this damage is enough to stop the growth of the bacteria
depending on the wavelength and frequency of laser irradiation used by the
dentist.

6. LASERS IN ORAL AND MAXILLOFACIAL
SURGERY
• Lasers have played an integral part in the evolution of practice of oral and
maxillo-facial surgery as the procedures can be executed efficiently with less
complication.
• There are many advantages such as :-
 Maintenance of sterile condition.
 Precise and accurate
 Decreased post-operative swelling
 Improved tissue scarring and healing
 More accessible
 Less instruments needed
 Less pain
 Less cost, staff and time

7. VARIOUS TYPES OF SURGERIES IN WHICH
LASER IS USED EFFECTIVELY:-
1. Laser in Implant (Peri-implantitis)
Laser makes it possible to remove diseased tissue around a dental implant
without causing any significant harm to the healthy tissue. It is gentle,
reducing inflammation and discomfort while encouraging new bone growth
to reinforce and save your implant.
2. Cosmetic facial Laser surgery
Laser is used to treat facial lesions and skin wrinkles by removing the surface
layer of skin allowing the underlying skin to re-epithilialize in a uniform
manner. E.g. tissue tags, epidermal nevi, lentigines, superficial pigmentation,
skin wrinkles, scar revision, melisma etc.
