Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

When providing dental care to child patients with a high level of dental anxiety, the range of approaches are divided into two sections - use of behavior management techniques and application of alternative methods for caries removal. In attempt to reduce dental anxiety, they can be mixed and matched in accordance with the dentists' choice. Owing to the promoted advantages Er:YAG laser turns into an ideal alternative technique for hard dental tissue therapy in anxious pediatric patients.This is a protocol for a randomized controlled clinical trial. The participants will be children aged aged 6-12 years, requiring conservative treatment of occlusal carious lesions on a second primary molar. Patients will be randomly assigned to experimental or control group via computer-generated sequence. In both groups Latent inhibition will be used as an anxiety-management technique. In the experimental group caries treatment will be performed with Erbium:YAG laser, whereas in the control group with the conventional rotary instruments. Outcome measures will be dental anxiety felt before and after the treatment and the dynamics of heart rate, registered during the treatment session.

Er:YAG laser therapy

Er:YAG laser will be used for enamel conditioning of the occlusal surfaces of the permanent molars before sealant application as well as the standardized caries treatment.

Group Type EXPERIMENTAL

Laser conditioning and Sealant application

Intervention Type PROCEDURE

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.

Er:YAG laser therapy

Intervention Type DEVICE

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.

Conventional therapy

Conventional rotary instruments will be used for caries treatment.
