A Cephalometric Study of Breathing Mode Influence on Dentofacial Morphology in Children of 6 To 12 Years
Journal Title: International Journal of Medical Science And Advanced Clinical Research (IJMACR) - Year 2019, Vol 2, Issue 3
Abstract
Background Mouth breathing is seen to cause facial and structural growth alterations, especially during childhood and has been discussed in medical and dental literature, since ages. The change in mode of respiration causes postural adaptations of the structures in the head and neck region producing the effect on the positional relationship of the jaws, teeth and perioral structures. The magnitude of the skeletal changes should be recognized early and the habit treated according to its aetiology, at the earliest, so that the postural changes do not cause permanent damage on the developing child. Aim and objectives To cephalometrically evaluate the effect of mouth breathing on the SN-Go.Gn and IMPA values and to compare these values in children who are nasal breathers. Material and methods 80 children aged between 6-12 years, following Otolaryngological examination to rule out obstructions, were divided into two groups. Group 1was mouth breathers, consisting of 40 children, and Group 2 was nasal breathers consisting of 40 children as control. Digital Lateral Cephalogram was taken of each subject in a standardized manner. Skeletal parameters were analyzed . Comparisons of groups were done by paired‘t’ test of the SPSS software. Results The SN-Go.Gn was found to be much higher in children who were mouth breathers. When comparing the IMPA values between mouth breathers and nasal breathers, mouth breathers showed greater angles than nasal breathers . The increase in values of SN-Go.Gn and IMPA suggest a development towards bimaxillary protrusion or mandibular prognathism in these children, if the mouth breathing habit is not intervened at the earliest. Conclusion The early recognition of such facial patterns may be utilized to identify breathing compromised individuals who are likely to develop aberrant growth patterns and various types of malocclusions.
