Introduction:
Pediatric dentistry skills differ from other dentist since they work with children that mainly need special care. Pedo dentist must diagnose and treat while children are comfortable.

First ruby lasers were used in treating enamel and dentin caries, and then new types were developed like: argon carbondioxide
Neodymium-Aluminum Garnet) (Nd:YAG)
Erbium-Yatrium-Garnet
diode lasers
Classification of laser: (1)
Classification of laser:
Advantages of laser use (4)
Precise and selective
Decrease in thermal necrosis in adjacent tissue compared to electrosurgical instruments
Sutures are usually not indecated since hemostatsis is achieved
Rapid healing
Less need for anesthesia
Less chair time
Disadvantages of laser use (4)
Special training
Expensive
More than one laser system is needed
Special care is needed vaporized aerosol may contain infective tissue particles potential risk of disease transmission from laser-generated aerosol exists
Laser application

Radiographs aren 't effective in diagnosing early caries
Enamel/dentin caries prevention
Laser fluoride therapy
Both laser and fluoride decrease ph >> thus enamel dissolute under very low ph
Removal of caries
By YAG laser with its antibacterial effect, decontamination of the affected layer will retain its remeneralizing potential.
No smear layer>> more retention
Laser on enamel before etching>> better marginal seal for composite.
Advantage of caries removal by laser(2)
Quite>> acceptance by patient
Less need for anesthesia
Selective absorption by laser for carious surface>>minimal invasive
Smear layer free cavity
Less thermal increase>> better for pulp chamber
Macroroughned surface>> more retention composite
Acid etch use can be avoided>> less leakage
Disadvantages(2)
Expensive
High training
Need for conventional handpiece to complete work
Pit and fissure sealant(1)
Pit and fissure sealant must prevent micro leakage so caries will not occur.
“If laser was used a delicate interlacing pattern of thin partitions and small knob like expansion will appear on enamel”(1)>>mechanical retention for resin
Removal of old restoration(1)
Avoided in case of amalgam due to release of mercury vapor.
Less traumatic to
