Bite and Sight: Is There a Correlation? Clinical Association between Dental Malocclusion and Visual Disturbances in Pediatric Patients

Aim: The aim of this study was to evaluate the correlation between malocclusions and visualdefects. Thisisacase-controlstudyevaluatingtheprevalenceofvisualdefectsinpatientswith different types of malocclusions. Methods: One-hundred and sixty patients aged from 5 to 14 were evaluatedusingtheROMAindextodetectmalocclusion;theoneswiththelowestscoreswereusedas the control group. They were also submitted to visual-capacity inspection for motility and refractive disorders. Results: Our work showed an enhanced prevalence of refractive defects or fusional vergence defects and alteration of eye movements (especially the saccades) in almost all dental malocclusions. Statistics: TheKappatestvaluesforROMAindexwerebetween0.643and1.00forthe intraoperator agreement (0.00 < p < 0.002) and between 0.773 and 1.00 for the agreement between operators (p = 0 < 0.001). The statistically significance level for the correlation malocclusion/visual defectswassetatp < 0.05. StatisticalanalyseswereperformedwiththeSTATAsoftware(version15.0, Stata Corp LP, College Station, TX, USA). Conclusion: Considering the high level of the statistical analysis and the accuracy of the methodology used, these data allows the establishment of a huge correlation between sagittal, transversal and vertical malocclusions with ocular disorders (myopia, hyperopia, astigmatism and ocular motility defects).
