Bifid uvulae is a silent abnormality in children which can almost exist without clinical problems but in some instances it is accompanied with either sub mucosal cleft and hypernasality.<br />Methods. In a cross sectional study, the examiners carried out oral examination of 3000 children and the structure of the uvulae was evaluated as normal or bifid.<br />Results. The prevalence of bifid uvula was 0.8 percent (25 children). Positive family history, familial marriage and positive teratogen exposure history were detected in four, twenty and eight percent of bifid uvalae cases, respectively.<br />Discussion. Bifid uvulue prevalence in European and American children was reported more than our findings. This gap may be due to different cultural habits as well as environmental factors.</span></font></font>http://jrms.mui.ac.ir/index.php/jrms/article/view/3503
