Aims and Objectives:Managing mild-to-moderate Class II malocclusion is one of the common and major challenges to orthodontists. Class II discrepancies with mandibular deficiency during active growth are usually treated using myofunctional appliances. Fixed functional appliances evolved due to the noncompliance with conventional myofunctional appliances. One of the latest Class II correctors is the PowerScope appliance. The purpose of this study was to determine the amount, time, and rate of molar correction and efficacy of PowerScope.Materials and Methods:A total of 10 participants, between 15 and 19 years’ age group (mean = 16.8 years; 5 males and 5 females), requiring treatment of Class II malocclusion were considered for this study. All routine records were made. After initial leveling and alignment, lateral cephalogram was taken in standardized natural head position using Planmeca ProMax unit. Later, PowerScope was installed and a patient was monitored every month for further adjustment and reactivation. On achieving Class I molar relation, skeletal, dental, and soft-tissue linear and angular parameters were measured using Dolphin Imaging Software. Amount, rate, and total treatment time for molar correction were measured. Molar correction was calculated by taking S vertical as reference plane. The obtained values were statistically analyzed using paired t-test.Results:There were statistically significant changes seen in dentoalveolar parameters such as lower incisor proclination, mandibular molar advancement, and reduction in both overjet and overbite. In skeletal parameters, due to the anterior positioning of the mandible, sagittal parameters showed statistically significant changes. In the soft tissue, a significant improvement in facial profile was seen, due to the anterior movement of soft-tissue pogonion.Conclusion:The results of this study have shown that statistically significant differences were found in dentoalveolar, soft-tissue, and skeletal parameters.
Acute appendicitis is a surgical emergency and requires surgical intervention. This is a study among 30 patients in tertiary care centre in south india
to compare the efcacy of early oral feeding compared to traditional late oral feeding. Early oral feeding was found to be superior in all aspects over
tradional oral feeding. Hence this can be promoted in all patients undergoing appendicectomy .
The aim of the present study was to explore a novel two-dimensional (2D) software technique and investigate the relationship between corresponding 2D and three-dimensional (3D) measurements on maxillary plaster casts of infants up to 6 months of age born with complete unilateral and bilateral cleft lip and palate (BCLP). Materials and Methods: Twenty-five series of plaster casts were made of infants with complete unilateral and BCLP up to 6 months and were subjected to photographs followed by digitization for 2D software (MAKHTER) measurements and additionally to cone-beam computed tomography scanner for 3D digitization and measurement. The corresponding 2D and 3D measurements of the selected linear distances, curve lengths, and surface areas were carried out, and the efficacy of our 2D software was assessed and compared with 3D using linear regression. Results and Conclusion: Our innovative 2D technique was found to be much reliable and effective as the values for different landmarks were found to be close with 3D. However, 3D method presented good accuracy error (0.8%) on measuring geometric objects. There were no statistically significant differences (P > 5%) noted for different methods (2D and 3D) for almost all the distances analyzed. Thus, 2D software could be used as reliable alternate tool for 3D measurements, and additionally, 3D values could be predicted using Deming regression analysis from 2D measurements values.
