Abstract

Human growth is very complex in nature characterised by considerable variation in an individual’s rate of physiologic and skeletal maturity. Variability is the law of nature because of infinite number of genetic possibilities present. No individuals are ever exactly alike. The growth factor is a critical variable in orthodontic diagnosis and treatment planning. Predicting the out come of treatment results in a growing patient is often more difficult than in a non growing patient. Prior knowledge of the amount along with rate, timing and direction of maxilla–mandibular growth in any given patient would be extremely useful for forecasting treatment out come.

Skillfull evaluation of growth left in a patient makes a difference in such growth modulations. Having an intrinsic indicator could be a boon for the clinician. Hence the search for such an intrinsic indicator was initiated in this study.

Abstract

Tongue is the most agile, versatile appendage in the body. It is the largest organ of the oral cavity. Dental arches are enveloped on both the sides by muscular tissues. Tongue alone counteracts various buccal forces exerted by cheek and lip musculature. Precise balance between these forces is utmost importance for normal inter and intra arch relationship. The unstable forces induced by abnormal functions such as mouth breathing, tongue thrust, swallowing and unilateral chewing and abnormal postures of oral circumferential muscles such as forward tongue thrust, tongue biting, low tongue at rest were correlated with varieties of malocclusion. Thus it is necessary for proper understanding of these structures. The purpose of this article is to discuss the role of tongue in malocclusion.
