AIM: The aim of this study is to describe oral health-related quality of life (OHRQoL) among patients who have had a complete dislocation of the tooth out of its socket (tooth avulsion). The study also sought to identify clinical evidence, associated with OHRQoL, of the ideal therapeutic choice after tooth avulsion among these patients under 18 years old. STUDY DESIGN: 73 patients under 18 year old were selected between 101 studied; they received different treatments, after one year adverse impacts on OHRQoL were measured using the 14-item OHIP. RESULTS: Our findings show that if patients got into tooth avulsion their quality of life is adversely affected. In this study, 21.2\% of subjects reported 1 or more of the 14 OHIP items during the preceding 12 months, which is significantly high. In group A just 4\% of subjects reported 1 or more of the 14 OHIP items, while in the other groups the percentage rose, reaching 50\% in group F. Group C D G reported a value of 20\%, while in group E this is 12\%. CONCLUSION This study shows how different treatment options have different effects on quality of life; the ideal one is the immediate replantation, when this is not possible, RPD or functional appliance seem to be the best choice.
