Since its inception, the field of dental medicine has had the challenge of trying to create a painless experience for the patient. The fear of pain attributed to anesthetic needle injection has been cited as an obstacle in providing appropriate dental care. 1 – 3 A variety of patient management techniques have been attempted to improve patient comfort during dental anesthetic administration, including but not limited to smaller gauge needle sizes, slow computer-regulated administration, distraction techniques, vibrating devices, and topical

A significant number of patients still perceive administration of local anesthesia as a painful and anxiety-causing dental procedure. Several methods have been described to reduce pain and anxiety caused by local anesthesia administration. These include buffering the local anesthetic, warming the local anesthetic, applying topical anesthesia before injection, reducing injection speed, and using fine needles with electric delivery devices. 1 Vibration stimulus is one of the nonpharmacologic methods used to reduce unwanted sensations of local

Bruxism is the jaw clenching or grinding of teeth that usually occurs during sleep. 1–5 It is synonymous with trismus when referring to tonic jaw clenching, and considerable jaw pain and tooth ischemic pain in particular can be generated by this form. Lifetime occurrence of at least some orofacial pain from a night of bruxing or daytime episodes of clenching or grinding, particularly at a time of unusual stress, approaches 100%. Point prevalence is estimated at 5–10% of the adult population, 5 6 and a minority of these individuals develop

A vibrating dental local anesthesia attachment (Vibraject, LLC, Calif) has been introduced in recent years. 1 This device was developed on the basis of the gate-control theory, 2 3 which states that pain transmission through A-delta and C nociceptive fibers is depressed at the secondary neuronal cell bodies in the dorsal horn if nerve impulses evoked by tactile sensation are simultaneously transmitted through A-beta tactile fibers. It is therefore supposed that vibrating a needle with Vibraject can result in a reduction in injection pain. The instructions

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

-implants during orthodontic treatment is strongly influenced by the perception of pain associated with the insertion procedure, frequently a reflection of the needle puncture for the application of infiltrative anesthesia. 1 , 7 The placement of mini-implants in the oral cavity with only the application of topical anesthesia has been suggested in the literature. 1 , 8 , 9 There are advantages involved in this practice, such as greater comfort for the patient, simplicity of the anesthetic technique, reduction in stress and anxiety of the patient before insertion of the

block anesthesia when other viable alternatives exist. 17 The aim of the present study was to compare the efficacy of lidocaine and articaine for intraoperative pain control during impacted third molar surgery. METHODS This study was approved by the Committee of the Ethics of Research on Human Beings of the School of Dentistry of the Federal University of Sergipe–UFS (protocol #32405914.1.0000.5546), and each patient gave written informed consent to participate in the study.
