The literature search was updated on 15th October 2021. Scrutiny of the titles and abstracts and later full text was done as per the inclusion and exclusion criteria. Data extraction Self-designed pre-piloted form was used by two reviewers. Quality appraisal AMSTAR-2 was used to assess the quality of systematic reviews, PRISMA was used to check reporting-characteristics and citation-matrix was used to evaluate study-overlap. Quality of evidence was assessed by using Kohler’s-criteria. Data analysis Qualitative synthesis was performed for describing the study characteristics, details of sampling and the tool of OHRQoL used. The meta-analytic data was used for evaluating the evidence and its strength for each of the outcomes. Results and interpretation A significant impact of all types of TDI on OHRQoL in children and adolescents was observed. The effect of uncomplicated TDI on OHRQoL in children and all ages showed no difference from controls. Though the quality of evidence in these interpretations was weak.
