PURPOSE To analyze the effects of detachment and repositioning of the medial pterygoid muscle on the growth of the maxilla and mandible of young rats through cephalometry. METHODS Thirty one-month-old Wistar rats were used, distributed into three groups: experimental, sham-operated and control. In the experimental group, unilateral detachment and repositioning of the medial pterygoid muscle w...

OBJECTIVES To test the hypothesis that there are no gender differences in the outcomes of patients with class II malocclusion treated with the headgear-activator Teuscher appliance (HATA). DESIGN Retrospective, longitudinal SETTING AND SAMPLE POPULATION Puerto Rico and Scotland, UK. Thirty-one patients requiring correction of class II division 1 malocclusions. EXPERIMENTAL VARIABLE Male a...

conclusions the relationship between calcification of tooth and maturation of cervical bones was significant. this suggested that tooth calcification stages from panoramic radiographs might be clinically useful as a maturity indicator. results all correlation values obtained were statistically significant (p < 0.001). correlations between dental development and skeletal maturity stage due to cv...

background the gonial angle is one of the most important measurements required for orthodontic treatment and orthognathic surgery. it is difficult to determine the accurate measurement of each gonial angle on cephalometric radiographs because of superimposition of the left and right angles. objectives the aim of the present study was to determine the right and left gonial angles on panoramic ra...

BACKGROUND The patient's head can be slightly rotated sagitally vertically or transversely within the head holding device. Because of such improper positions due to the head rotation, an error can occur in cephalometric measurements. The purpose of this study was to identify the potential projection errors of lateral cephalometric radiograph due to head rotation toward X-ray film in the vertica...

Lateral cephalometric radiography is commonly used as a standard tool in orthodontic assessment and treatment planning. The aim of this study was to evaluate the available scientific literature and existing evidence for the validation of using lateral cephalometric imaging for orthodontic treatment planning. The secondary objective was to determine the accuracy and reliability of this technique...
