Investigation of the relationship between the stomatognathic system spi̇ne posture and pelvic symmetry in adolescence ndividuals

This study was planned to examine the relationship between the stomatognathic system, spine posture and pelvis symmetry. 91 healthy adolescence with a mean age of 14,01±1,4 years were included in the study. For stomatognathic system, temporomandibular range of motion with millimeter ruler, cervical joint range of motion and craniovertebral angle measurement with goniometer, tragus-wall distance measurement with tape measure, kyphosis and lordosis angle measurement with Baseline Bubble Inclinometer®, trunk rotation angle scoliometer for scoliosis, lower extremity length measurements for pelvis symmetry were made using a tape measure. SPSS and R programs were used data analysis and p<0,05 statistical significance level was accepted. A moderately strong correlation was found between the craniovertebral angle and maximum mouth opening and protrusion values of the adolescence individuals included in the study (r=0,445-0,452; p<0,01). A moderately strong correlation was found between tragus wall distance and maximum mouth opening and laterotrusion (r= -0,421; -0,489; p<0,001) values. Strong between kyphosis angle value and maximum mouth opening (r= -0,679; p<0,001); moderately strong with the amount of protrusion (r= - 0,558; p<0,001); a weak correlation was found with laterottrusion (r= -0,330; -0,340; p=0,001) values. A weak correlation was found between scoliosis rotation angle and maximum mouth opening (r= -0,276; p=0,008), protrusion (r= -0,268; p=0,010) and laterotrusion (r= -0,209; -0,214; p=0,047) values. There was a weak correlation between lordosis angle and maximum mouth opening (r= -0,389; p<0,001) and laterotrusion (r= -0,311; p=0,003) values. Between leg length difference and maximum mouth opening (r= -0,232, p=0,026), protrusion (r= -0,227, p=0,030) both sides laterotrusion (r= -0,216; -0,214, p<0,05) values weak relationship was found. Laterotrusion (ρ= -0,508; -0,517, p<0,05) values with the direction of scoliosis curvature and ipsilateral tragus wall (ρ= 0,482; 0,490, p<0,05) and a moderate correlation between opposite side lateral flexion and rotation values was found (ρ= -0,487; -0,427, p<0,05). A weak correlation was found between the direction of curvature and the distance between the spina iliaca anterior superior-medial malleolus (ρ= - 0,355; -0,349, p<0,05) on the ipsilateral side. It was concluded that there is a significant relationship between the stomatognathic system and spine posture and pelvis symmetry in adolescences ındividual.
