Diastema is a term describing the spaces between teeth, often seen in anterior teeth. The presence of more than one diastema is called polydiastema. Many etiological factors are held responsible for the formation of diastema. Hypertrophic frenulum, genetics, anterior traumatic bite, tongue thrusting, habits such as finger and/or lip sucking, wedge laterals, supernumerary teeth, mesiodens, microdontia, missing tooth, tooth-arch size mismatch, buccal angulation, odontoma and cysts are some of these. Childhood diastema, called ugly duckling, seen in the anterior region as a result of the pressure applied to the lateral tooth roots by the upper canines during the transition to the permanent dentition, is a physiological condition and is considered normal. Permanent diastemas can be closed with orthodontic, prosthetic and restorative treatments because they negatively affect aesthetics and function. Advances in adhesion in today's dentistry allow the aesthetic rehabilitation of diastemas with direct composite resin restorations. The aim of this case series is to describe the aesthetic rehabilitation of patients with diastema and polydiastemas using different techniques with direct composite restorations.
