Therefore, it is crucial to assess their effects on children&rsquo;s oral health-related quality of life (OHRQoL). This study aimed to assess the effect of oral health status on OHRQoL of 2- to 5-year-old children in Sari, Iran. &nbsp;&nbsp;</span></span></span></span><br> <span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:9.0pt"><span style="font-family:" verdana=""><span style="color:#2e74b5">Materials and Methods:</span></span></span></b><span style="font-size:9.0pt"><span style="font-family:" verdana=""> This cross-sectional study was conducted on 540 randomly selected children between 2 to 5 years. Their decayed, missing, and filled teeth (DMFT) indices was determined by oral clinical examination. The Early Childhood Oral Health Impact Scale (ECOHIS) was completed by the parents. SPSS 16 was used for statistical analysis by the Chi-square test, independent t-test, and ANOVA.</span></span></span></span><br> <span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:9.0pt"><span style="font-family:" verdana=""><span style="color:#2e74b5">Results:</span></span></span></b><span style="font-size:9.0pt"><span style="font-family:" verdana=""> The<b> </b>ECOHIS mean scores in the Family Impact Section (FIS) and Child Impact Section (CIS) were 1.8&plusmn;3.0 and 2.7&plusmn;4.2, respectively. The mean DMFT score of children was 3.2&plusmn;3.07, with 47% having a DMFT of 0. The frequency of TDI was 11.5%. The DMFT index and ECOHIS were significantly correlated (r=0.571, P<0.001). A statistically significant correlation was found between ECOHIS and TDI, indicating lower quality of life (QoL) in patients with a history of TDI (P<0.001).</span></span></span></span></div> <div style="text-align: justify;"><span style="font-size:13pt"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:9.0pt"><span style="font-family:" verdana=""><span style="color:#2e74b5">Conclusion:</span></span></span></b> <span style="font-size:9.0pt"><span style="font-family:" verdana="">Children&rsquo;s oral health considerably affects their own and their parents&rsquo; QoL.
