The majority of dental patients suffer some symptoms of anxiety. In order to solve this problem, the dentist must include the anxiety control and gradually reduction in the treatment planning. It has been proved that stressed patients have longer treatments and in some cases further complications and pain. Thus, the purpose of this publication was to determine the prevalence and the severity of this problem, moreover knowing the best way to treat it in each case. We conducted a systematic review of the literature on any dental treatment achievable in a dental practice, and finally, we focused the attention on the anxiety during orthodontic treatments. The prevalence varies in the studies, but with an average of over 50% in almost all cases. The methods used to grade the severity are subjectives (visual scales and surveys) and objectives (through the determination of salival cortisol, which production is trigger in every alarm stimulus). Among the methods for its control the anxiolytics are the most common. Finally, focusing on orthodontic treatments are considered painful in 98% of the patients, they also have a clear anxiety symptoms within the first 24 h after each appointment.
