| Abstract | ||
| Aims : To evaluate the correlations between the skeletal measurements and soft tissue measurements in males and females. Materials and Methods: Eighty students (40 males and 40 females) were selected aged (12-14) years with class I normal occlusion from intermediate schools in Mosul City . A standar-dized lateral cephalometric radiograph was taken for each student, eighteen variables, 9 angular (6 ske-letal and 3 soft tissue ) and 9 linear (3 skeletal and 6 soft tissue) were used in this study. Results: In males, angle of facial convexity positively correlated with angle of skeletal convexity and negatively with the angle describes the relationship of the maxillary and mandibular bases in the sagittal planes.The length of mandibular corpus was positively correlated with upper lip thickness, lower lip thickness at labral inferius and upper lip height . Upper lip thickness at labral superius was positively correlated with angle defines the anteroposterior position of maxilla in relation to anterior cranial base and angle indicates the anteroposterior position of the mandible in relation to the anterior cranial base.Lower lip height was positively correlated with the mandibular plane angle .In females, angle of facial convexity was positively correlated with angle of skeletal convexity and negatively with the an-gle describes the relationship of the maxillary and mandibular bases in the sagittal planes. The angle measures the protrusion of upper lip relative to the inferior border of the nose was negatively correlated with angle of skeletal convexity and mandibular length and positively with angle describes the relation-ship of the maxillary and mandibular bases in the sagittal planes.Angle of skeletal convexity was posi-tively correlated with upper lip thickness at point A and upper lip thickness at labral superius . The mandibular plane angle was positively correlated with lower lip height. The angle describes the rela-tionship of the maxillary and mandibular bases in the sagittal planes was positively correlated with labiomental angle and negatively with upper lip thickness at labral superius . The mandibular length was negatively correlated with labiomental angle and positively with upper lip thickness at point A ,upper lip thickness at labral superius , lower lip thickness , soft tissue thickness at the chin , upper lip height and lower lip height . The length of the mandibular corpus was negatively correlated with labi-omantal angle and positively with upper lip thickness at point A and upper lip thickness at labral supe-rius .The length of the maxilla was positively correlated with upper lip thickness at point A , upper lip thickness at labral superius and lower lip thickness. Conclusions:There were no consistend correlations between soft and hard tissue structures , some are positively correlated others are negatively correlated and some of them are completely independent. | ||
