Effect of Direct Anterior Diastema Closure on Quality of Life and Dental Anxiety

The aim of this study is to evaluate the effects of non-invasive direct anterior diastema closure on dental anxiety and oral health-related quality of life in adults with maxillary anterior diastema. Direct composite resin restorations are widely used for diastema closure due to their minimally invasive nature, cost-effectiveness, and ability to be completed in a single clinical visit. However, limited information is available regarding the psychological and quality-of-life outcomes of this treatment. In this prospective single-arm clinical study, adult participants presenting with anterior diastema receive non-invasive direct composite restorations for diastema closure. Dental anxiety and oral health-related quality of life are assessed using the Modified Dental Anxiety Scale (MDAS) and the Oral Health Impact Profile-14 (OHIP-14). Participants complete these questionnaires before treatment and three months after the restorative procedure. The study aims to determine whether direct anterior diastema closure improves oral health-related quality of life and reduces dental anxiety in affected individuals.
