RESUMO
INTRODUCTION: The aim of the study is to assess and correlate the different cephalometric parameters used to determine the vertical jaw relationship. METHODS: Cephalometric radiographs from 148 patients were assessed and comparison was made using all eight parameters. Statistical analysis was performed using mean, standard deviation and coefficient of variance. A correlation was found between different variables using the Pearson's correlation coefficient. RESULTS: In the entire sample, the basal plane angle displayed the most variable distribution, while the R angle displayed the most homogeneous distribution. There was a significant correlation found between the Jarabak ratio, Steiner's mandibular plane angle (SN-GoGn), Frankfort mandibular plane angle (FMA), R angle, and DR angle. There was a moderate to weak correlation between the Y-axis, basal plane angle, and facial height ratio with other skeletal analyses. CONCLUSION: Among angular variables DR angle, R angle, SN-GoGn and FMA can be used and among linear variables Jarabak ratio could be used reliably to assess the growth pattern. It suggested that in order to obtain an accurate evaluation of the vertical jaw relationship, a variety of measurements should be combined.
RESUMO
This case report demonstrates an innovative technique involving concomitant correction of a traumatic extrusive luxated tooth, the mobility of which was being aggravated by anterior occlusal contacts, along with transverse rapid maxillary expansion to capitalize on the advantage of residual growth and simplify the need for comprehensive fixed orthodontic appliance. By incorporating a molar tube into the acrylic splint of the bonded Hyrax expander adjacent to the buccal surfaces and parallel to the buccal cusps of the maxillary first molars, effective intrusion of traumatically extruded upper incisor was achieved concomitantly using a modified intrusion arch during the passive stabilization period after expansion, thereby reducing treatment time. This enabled the immediate correction of extruded tooth and reduced the overall treatment duration and the complexity of post-expansion fixed mechanotherapy, improving compliance and uplifting the self-esteem of the patient. The modified bonded Hyrax assembly can serve as a versatile interim appliance for the simultaneous management of a variety of orthodontic problems such as crowding, spacing, and incisor proclination without compromising the basic integrity of the bonded assembly.
RESUMO
Mucinous tubular and spindle cell renal cell carcinoma is a rare and recently described subtype of RCC. We present the case of a 45-year-old woman with incidentally detected left renal mass. Imaging revealed a large mass and left radical nephrectomy was performed, histopathology revealed it to be a mucinous tubular and spindle cell carcinoma with sarcomatoid change. She is under close follow-up for the last 6 months
