Patients receiving dental infiltration anesthesia generally experience anxiety related to the injection and pain resulting from puncture of the oral mucosa and tissues or injection of anesthetic solution. When promoting safety of dental care, it is therefore important to establish a method of local anesthetic injection that does not give rise to pain and anxiety. Slow, low-pressure injection is the key to painless and comfortable delivery of local anesthetic. 1 However, standards for injection speed and pressure have not been clarified. In the

The relevance of psychology and behavioral sciences is ever increasing both in dental education and in clinical practice. A high percentage of patients are so fearful of dental care as to delay or avoid attendance. Other than avoidance behavior, dental anxiety has a wide-ranging and dynamic impact on a person's life. Therefore, careful assessment of anxiety and treatment is an essential step for appropriate patient management and overall quality of care. The evaluation of dental anxiety can be performed with a wide range of

Traditionally, the practice of dentistry has an enduring association with fear and apprehension. These feelings of anxiety continue despite advances in dental techniques. It has been reported that 23 million people with dental fear were more willing to see a dentist if a form of sedation was offered. 1 Consequently, the use of this modality is important in the provision of dental treatment. In fact, a current survey of recent US dental graduates reported that 93.7% perceived a need for sedation services within their respective patient
