Before the examination process, the child was asked to select one of the five faces on the Facial Image Scale. The dentist evaluated and scored the patient's behaviors based on the categories in the Frankl Behavior Scale. Parents were asked to answer the questions in the Corah Dental Anxiety Scale on behalf of their children to assess their dental anxiety, and results were scored. Subsequently, the children's heart rate was measured and recorded with a pulse oximeter attached to the index finger of the left hand. Prior to the examination procedure, The patients in Play Group played a mobile game called 'Dentist' before the examination. After that patients were examined, and their anxiety levels were assessed using the same methods following the examination procedure

Before the examination, the child was asked to choose one of five faces from the Facial Image Scale. The dentist assessed and scored the patient's behaviour using the Frankl Behaviour Scale. Parents were asked to complete the Corah Dental Anxiety Scale on behalf of their children to assess their dental anxiety and the results were scored. The children's heart rate was then measured and recorded using a pulse oximeter attached to the index finger of the left hand. The researcher then read the storybook "Elif Goes to the Dentist" and showed the children pictures of dental instruments as described in the book. Behavioural techniques were used to examine the patients, and their anxiety levels were assessed after the examination using the same methods.

Parents were asked to answer the questions on the Corah Dental Anxiety Scale on behalf of their children to assess their dental anxiety, and the results were scored. The children's heart rate was then measured and recorded using a pulse oximeter attached to the index finger of the left hand. Patients in the video group then watched an animated video entitled 'First meeting with the dentist' before the examination, and dental instruments were introduced using the terminology mentioned in the video. Using behavioural techniques, the patients were examined and their anxiety levels were assessed using the same methods after the examination.

Changes in anxiety levels were measured by playing a mobile game to children before dental examination.

We evaluated the effects of reading informative books, playing mobile games and watching videos after the dental examination on dental anxiety by measuring the Facial Image Scale (In the facial image scale consisting of 5 different faces, the happiest face is given a value of 1 while the unhappiest face is given a value of 5 and scoring is done according to the face chosen by the children.)

We evaluated the effects of reading informative books, playing mobile games and watching videos after the dental examination on dental anxiety by measuring the Frankl Behaviour Scale, (Frankl Behavior Scale: is based on the observation, evaluation and scoring of the child's behavior by the dentist. In this scale, which is filled in by the dentist, the child's behavior in different situations is classified as strongly negative (1), negative (2), positive (3), strongly positive (4). )

We evaluated the effects of reading informative books, playing mobile games and watching videos after the dental examination on dental anxiety by measuring the Corah Dental Anxiety Scale (Corah Dental Anxiety Scale: It consists of four short questions designed to measure dental anxiety levels related to dental treatments. Each question has 5 answers and the answers are scored from 1 to 5 by the physician. A score of less than 13 indicates a low level of anxiety, 13-14 indicates a moderate level of anxiety, and 15 and above indicates a high level of anxiety. If the child is too young to understand the questions, the questions can be answered by the parent or caregiver.)
