Evaluation of Tongue Force on Mandibular Incisor in Various Malocclusions

Objectives: The aim of the study is to evaluate the tongue force on the mandibular incisors in various malocclusions and among genders. Material and Methods: 512 subjects (340 females and 172 males) within the age group of 18-28years were selected for the study. The subjects were divided into three groups according the molar relation of the subjects. Molar relation and the tongue force exerted on the mandibular incisor of the subjects were recorded using a diagnostic kit and a Flexiforce resistive sensor respectively. Tongue force at rest (TFR), during swallowing (TFS) and maximum tongue force (MTF) were measured. Results: There was a significant increase in MTF among males than females. A significant relation among the groups when TFR and TFS were compared was also found. Conclusion: TFR and TFS were found to be influential in causing malocclusion and also a stronger tongue musculature among males than females was concluded while comparing MTF.
