Abstract: Postoperative pain in dentistry is always a task for the clinician. Subdividing broadly the pain into the field of oral surgery, endodontics and restorative dentistry it is more easily to assess the aetiology and management. This review study addressed the value of assessment using the previously mentioned subgroups as a general area of interest. It is worth noting that postoperative pain may be expected in various dental procedures. Post-surgical pain affects, in a very high degree, patients comfort and sequentially the dental job.
