Summary

Objective: To assess and compare the 2940 nm erbium:yttrium-aluminum-garnet (Er:YAG) laser versus a conventional rotary treatment during cavity preparation in children with regard to anxiety level, pain perception, restoration integrity, and bond interface quality.

Materials and Methods: In a randomized, blinded trial using a split-mouth design, forty (9-12-year-old) children with 80 carious deciduous molars were included. The cavity in one quadrant was treated conventionally using a bur, while the cavity in the other quadrant was prepared using an Er:YAG laser. Venham's dental anxiety scale and pulse rate measurement using a fingertip pulse oximeter were used to evaluate dental anxiety levels. The Wong-Baker facial pain rating scale and the number of local anesthesia required during both interventions were further applied to investigate pain perception. At the 1-year follow-up, clinical examinations was conducted and the integrity of the restorations was clinically assessed according to the Ryge criteria. Lastly, the restored teeth were extracted and histologically evaluated for bond interface quality using scanning electronic microscopy.

Conditions

  • Dental Caries

Interventions

DEVICE

Er:YAG laser system (Doctor smile, Pluser, Italy)

The Er:YAG laser offers a virtually painless alternative to conventional methods of caries removal, and its adoption in clinical practice could greatly reduce children's fear of going to the dentist. Caries removal is one of the leading reasons for dentist visits among children, and many children become fearful at the mere thought of a drill touching their teeth, before they even hear the sound. Laser caries removal could go a long way toward eliminating children's fear of going to the dentist; it is virtually painless, and most children are able to get through the entire procedure without needing local anesthesia.

DEVICE

Master Torque high/low-speed air rotor handpiece (KaVo Dental, Charlotte, North Carolina, USA)

Mechanical removal of carious lesions with a rotating handpiece and bur instruments is the most often used approach for treating dental caries because it is cost-effective, timesaving, and simple. However, these procedures have many drawbacks, including the potential for removing healthy tooth structures, vibration and noise, which can cause the patient anxiety and pain, thus necessitating local anesthesia.
