Aim: Dental malocclusion and jaw misalignments are the foremost reasons for airway constriction. To facilitate anterior mandibular repositioning and the concomitant anterior positioning of the tongue can induce the expansion of the pharyngeal airway. The study aimed to compare comprehensive treatment outcomes of fixed and removable mandibular advancement appliances on the width of the pharyngeal airway space.
Methods: Twenty growing patients with skeletal Class II malocclusion were placed into two groups: Advansync2 and twin block. Patients were advised to use mandibular advancement appliances (MAA) for 9–12 months. Lateral cephalograms and the Epworth Sleepiness Scale (ESS) were evaluated to assess alterations in the pharyngeal airway space and quality of sleep at two intervals. The chi-square test, one-way ANOVA and Duncan’s post hoc test were used for statistical analysis. P-values<0.05 were considered as significant.
Results: Based on the results, only the change in PNS-V measurements indicated a significant difference between appliances. Advansync2 showed more change (0.70±2.45 mm) compared to twin block (-1.80±2.34 mm), indicating a statistically significant difference (p=0.032).
Conclusion: A significant reduction in the ESS score in both groups was observed without any significant differences between them.

Aim: Orthodontists and patients prefer minimal time for orthodontic treatment. The submucosal injection ofplatelet-rich plasma (PRP) helps to provide tooth movement without surgery or alveolar bone loss. Thepurpose of this research was to assess the rate of space closure using PRP injection with the conventionalmethod.Methods: In this preliminary study, 10 patients aged 14-20 years, requiring first premolar extractions in botharches using MBT technique were included. This was a split-mouth study wherein, on one side (experimental),space closure was done using a submucosal injection of 0.7 ml PRP, and the other side (control) was subjectedto conventional space closure using an active tie back with a constant force of 200 gm. Statistical analysis wasperformed using a paired t-test. P-value <0.05 was set for statistical significance.Results: The findings of the research showed no significant difference in the rate of space closure between thecase and control groups in the maxilla (P=0.073); however, there was a significant difference between theexperimental and control groupsin the mandible (P=0.04).Conclusion: Analyzing space closure rate between the control and experimental side showed that PRPinjection did affect the acceleration of space closure in the mandible.
