Abstract
Acceptance of lasers as alternatives and accessory tools to traditional methods in dental medicine has created an explosion of interest. Er:YAG laser is recommended for enamel conditioning. There is no study evaluating the anxiety in children during fissure sealing procedures when using Er:YAG laser compared to the routine application technique. To evaluate the objective and subjective stress parameters in children during a preventive procedure when using Er:YAG laser for additional enamel conditioning before pit and fissure sealant application compared to the routine clinical application technique. The study included sixty-four 6-12-year-old children, divided into two equal treatment groups. A standardized fissure sealant application was performed, as in the intervention group before acid etching, the occlusal surfaces of teeth were conditioned with Er:YAG laser (2940 nm). During the procedure, objective and subjective stress parameters were recorded. Significantly lower degree of dental anxiety was found at the end of the dental visit of the study group (p<0.001). During the professional cleaning of the tooth surface, the mean heart rate was low (95.55±14.29 bpm) within the physiological normal range. The objective and subjective stress parameters show no significant differences between the two subgroups during sealing procedure (p>0.05). Application of Er:YAG laser during sealant application does not provoke anxiety and is well accepted by children in dental environment. Preventive procedures at the beginning of a dental visit decrease the initial levels of dental anxiety and contribute to an effective treatment process.
