Each patient meeting the inclusion criteria and assigned to a specific study group will enter the clinic for dental examination. The examining dentist, wearing the selected PPE will communicate with patient and parent, taking personal, previous and current history, and carrying out simple examination not involving the use of sharp instruments, provoking pain or investigations as radiographs. The process should take from three to five minutes. Then, the child will be escorted to another room to meet a blinded accessor, where he assesses the child's anxiety using the Arabic version of children's fear survey schedule-dental subscale CFSS-DS.
