Objective:
as regards to  prevalence of mouth breathing and its complications, The  panoramic view of children with mouth breathing as a routine initial accessible radiographic examination, was assessed; considering  Confounding  factors such as the magnification, dimensional changes, type of the x-ray machine and head position during imaging. We tried to innovate standardization of nasal cavity analysis in panoramic radiography, in addition to creating specified and reliable parameters, and investigate if there is any difference between these parameters in mouth breathing patients than in those with normal breathing.
Methods & Materials:
This was a “case-control” and “analytic” study which assessed 30 patients with Mouth breathing and 30 patients with normal breathing, in the range of 9-12 years with equal numbers of both sexes, in both groups. After tracing the panoramic radiographs, five angular and proportional variables was created and measured, and T-test was performed and the level of significance was found. For evaluation of nasal septum deviation we used Chi-square test.
 Results:
"NL" and "NL.B" parameters and irregularity in internal structures of the nasal cavity showed a significant difference in mouth breathing group. Right and left nasal cavity width in each person, separately in two groups- mouth breathing and normal breathing- showed no significant difference.
 Conclusion:
The proportional and angular parameters were reliable for assessment and comparison of nasal cavity in mouth breathing children than in those with normal breathing.
