ObjectiveTo perform an overview of systematic reviews (SR) assessing the impact of malocclusion treatments (Orthodontic Treatment - OT and/or Orthodontic Surgical Treatment - OST) on Oral Health-Related Quality of Life (OHRQoL). Materials and methodsA search strategy was conducted in electronic databases until June 7th, 2021, followed by a manual search in grey literature and registration databases. Two independent authors applied the eligibility criteria, extracted the data, assessed the risk of bias (AMSTAR-2), and performed the certainty of evidence (GRADE) evaluation. Meta-analysis was planned to be carried out in RevMan 5.3 (with 95% confidence intervals (CI) considering p < 0.05), in case of homogeneous studies considering OHRQoL instrument and time of follow-up. ResultsA total of 126 articles were accessed on the database, 18 registers, 33 records on grey literature and 3 articles by means of citation searching. After duplicates removal and eligibility criteria analyses, 15 SR were included. From that, 13 showed improvement in OHRQoL after OT and/or OST. The methodological quality ranges from high (n = 2), to critically low (n = 9). Meta-analysis was conducted. Improvement on OHRQoL after a 6-month OST using the OQLQ-22 (p < 0.00001; 19.65; CI: 12.60-26.70) and OHIP-14 instruments (p < 0.00001; 10.70; CI: 9.89-11.51); and after a 6-month OT using the CPQ 11-14 instrument (p = 0.010; 3.57; CI: 0.86-6.28) with very low certainty of the evidence for all outcomes was observed. ConclusionsAlthough most SR selected in this overview are characterized by a critically low quality, as well as very low certainty of the evidence, OT and/or OST seem to have a positive impact in improving the OHRQoL.
