Er:YAG Laser Therapy in Combination With Behaviour Management Technique in Reducing Anxiety Among Paediatric Patients

Summary

The aim of the study is to assess the efficacy of a modified version of the behaviour management technique Latent inhibition in combination with Er:YAG laser for achieving reduction of dental anxiety in paediatric dental patients. The main objectives are to compare dental anxiety felt during the laser and conventional dental treatment. The outcomes will be dental anxiety assessment by a self-reported anxiety during treatment in both group as well as measurement of heart rate dynamics during the procedures.

Interventions

PROCEDURE

Laser conditioning and Sealant application

Sealant application protocol includes: a low-speed rubber cup and pumice paste (CleanPolish, Kerr) will be used for 30 seconds for cleaning and polishing of the occlusal surface of the chosen permanent molar; tooth surface will be washed for debris and organic residue removal and dried with air spray; isolation; laser conditioning of the occlusal enamel surface. The parameter settings used will be: tip-to-tissue distance 1.5mm from the tooth surface; tip diameter 600 µm; laser energy 70 mJ; pulse frequency 10 Hz; water spray level 8; average power 0.7 W; energy density 67 J/cm2; tooth surface will be etched with 35% phosphoric acid gel (Etching gel, DMP Ltd) for 30 seconds and rinsed for the same time; reisolation; tooth surface will be dried with air spray for 15s; fissure sealant application (Pit\&Fissure Sealant, DMP Ltd); light cured for 20 seconds.

DEVICE

Er:YAG laser therapy

Er:YAG laser (LiteTouch, Light Instruments LTD), emission wavelength 2940 nm will be used for caries removal - parameters: enamel removal - energy 100-200mJ; density 9.84-13.03 J/cm2, pulse frequency 20Hz; tip diameter 800 μm; water spray level 8; tip-to-tissue distance 0.5÷1 mm form the tooth surface; dentin removal - energy 100mJ; density 9.84 J/cm2, pulse frequency 20Hz; tip diameter 800 μm; water spray level 8; tip-to-tissue distance 0.5÷1 mm form the tooth surface. Restoration with compomer.

PROCEDURE

Conventional therapy

Conventional rotary instruments will be used for caries removal - high-speed and low-speed dental handpieces. Restoration with compomer.
