Evaluation the Effect of Using Preoperative Ibuprofen Versus Low Level Laser Therapy on Inferior Alveolar Nerve Block

Acute apical periodontitis (AAP) is an inflammatory condition of the periapical tissues of the periodontium, usually resulting from irreversible pulpitis and pulpal necrosis. Patients with AAP often have moderate to severe pain, which results in the need for emergency treatment. Patients with AAP usually present with dull, throbbing, constant pain; absence of swelling; a negative or delayed positive result on vitality testing; absence of thermal sensitivity of the tooth; and pain on biting or percussion.The treatment of these teeth is root canal treatment. Pain control during root canal treatment is essential for several reasons. First, patients desire and expect that their treatment should be free of discomfort. Second, good intra-operative pain control helps to reduce post-operative pain and simplifies its management. Third, patients will be reluctant to have further root canal treatment in the future if they have had a bad experience as a result of pain during treatment. Hence, pain-free treatment should be every dentist's aim. The amount of pain experienced during treatment is related to the condition being treated teeth with irreversible pulpitis and acute apical periodontitis were significantly associated with more treatment pain than devital teeth and infected canals with apical periodontitis.In another study, molars and teeth with irreversible pulpitis had more intra-operative pain than single-rooted teeth and devital teeth, infected root canals. Local anesthesia is the most common method used for pain control during root canal treatment. However, other strategies can also be employed in some cases such as pre-treatment anti-inflammatory systemic medications, and methods to reduce discomfort associated with injections. The use of pre-operative medication reduce pain and inflammation at the treatment site. Several studies have been performed to investigate the effectiveness of this approach using a variety of drugs such as benzodiazepines, NSAIDs and corticos
