Routine clinical care will be applied to the control group. No action will be taken.

Children aged 5-6 who come to the emergency room with their parents and will receive inhalers will be given stress ball balls in the stress ball group before and after the procedure and will be told to play with them until the procedure is completed. In the book reading group, parents will be asked to read a book about hospital fear, prepared by researchers.

Children arriving at the hospital's emergency department and meeting the study criteria will be randomly assigned to the stress ball group. Before inhalation therapy, the child will begin squeezing the chosen stress ball. This will distract their attention, transforming the frightening hospital environment into a fun one. The questionnaires will be completed by the nurse and family five minutes before, during, and after the inhalation therapy.

It is a form consisting of a total of 13 questions including the child's age, gender, diagnosis, duration of treatment, number of treatments (How many times did the child come to the clinic?), the status of receiving information about dental treatment and the person who received the information, the education level and occupation of the mother and father, the place where the family lives and the economic situation. It was prepared by the researchers in line with the literature.

"Child Anxiety Scale-State" scale developed by Ersig et al. in 2013 measures the state anxiety of children aged 4-10 years. In 2017, Gerceker et al. carried out Turkish validity study for the scale. CAS-S (State) is designed as a thermometer. At the bottom is the bulb chamber, and upward are horizontal lines. Each horizontal line represents a score, and the thermometer has 10 points. The bulb chamber at the bottom is 0 points and indicates that there is no anxiety. It is interpreted as the rise of anxiety as it rises upwards. The peak is worth 10 points and refers to the highest anxiety.

This scale was developed by McMurtry et al. in 2011. In 2018, Gerceker et al. carried out a Turkish validity study for the scale. The scale is aimed at children aged 5-10 years. The facial muscle changes in fearful expressions are drawn by a graphic artist based on photos of frightened faces. In this scale, the child is shown a scale containing five facial expressions that are evaluated between 0 and 4 points. While 0 point refers to no fear; 4 points refers to the highest fear.
