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
