Abstract

Objective: Evaluate the relationship between occlusion and tongue range of motion of patients with ankyloglossia at  the National hospital of Odonto-Stomatology, Hanoi. Methods: A cross-sectional descriptive study was conducted on 60 patients, evaluating and tongue range of motion, evaluating crossbite, overbite, and malocclusion according to Angle and mandibular plane angle. And studying the relationship between the above factors. Results: Although patients with more severe anterior tongue movement had a higher risk of crossbite and increased mandibular plane angle (OR=1.82, OR=1.63) and those with a lower risk of overbite and class III malocclusion (OR=0.25. OR=87). Or more limited posterior tongue movement increased the risk of crossbite (OR=8.83) and vice versa with the risk of overbite, class III malocclusion, increased mandibular plane angle (OR=0.51; OR=0.9; OR=0.68). However, all of the above associations were not statistically significant (p>0.05). Conclusion: No association was found between the tongue range of motion in patients with ankyloglossia and crossbite, overbite, class III malocclusion, and increased mandibular plane angle. Research on larger sample sizes is needed to avoid missing risk factors, as well as increase the number of subjects with each degree of tongue mobility restriction, thereby helping to more accurately assess the association with malocclusion.
