Among young adult patients, persistent but untreated malocclusions may have psychological and social impacts on the individual’s quality of life. The objective is to gain knowledge of malocclusions and its impact on oral health-related quality of life (OHRQOL) in young adults. Five databases (PubMed, Web of sci, Cochrance, CINAHL, Google scholar and DOS) were searched. The search produced 601 titles and abstracts. Based on pre-established criteria, the full-text versions of 46 articles were obtained, 10 of which satisfied the inclusion criteria. All ten were of cross-sectional design, seven studies reported that orthodontic treatment need was associated with OHRQoL. Two studies stated that increased orthodontic treatment need had a negative impact on OHRQoL. In addition, six studies revealed that malocclusions predominantly affected the dimensions of self-esteem, social disability, psychological discomfort. Two studies indicated that dental aesthetics have a significant effect on perceived OHRQoL. In conclusion, the scientific evidence was considered strong since seven studies reported that orthodontic treatment need was associated with OHRQoL. Two studies reported that malocclusions in the aesthetic zone have negative effects on OHRQOL. In conclusion, six studies indicated that malocclusion effect predominantly in the dimensions of psychological discomfort
