ABSTRACT
BACKGROUND: Orthodontic tooth movement is often time-consuming and can cause patient discomfort. Various techniques to accelerate tooth movement such as micro-osteoperforation and platelet-rich plasma (PRP) have been extensively researched. PRP is an autologous component rich in growth factors and mediators that promote cell proliferation and differentiation, essential for orthodontic tooth movement. Freeze-drying PRP enhances its shelf life and clinical applicability.
AIM: The present study aims to evaluate the efficacy of lyophilised platelet-rich plasma (LPRP) and micro-osteoperforation (MOP) in accelerating canine retraction in patients with class I bimaxillary protrusion undergoing fixed orthodontic treatment.
MATERIALS AND METHODS: This randomized split-mouth clinical trial was conducted at the Department of Orthodontics and Dentofacial Orthopaedics, Rajas Dental College and Hospitals, Tirunelveli. Nine patients with Class I bimaxillary protrusion were randomly assigned to receive either MOP or LPRP on the contralateral side. Tooth movement was assessed at one- and two-months post-intervention using dental cast. Statistical analysis of the data was performed, with a p-value of < 0.05 considered statistically significant.
RESULTS: The mean age of the participants was 21.00 ± 1.94 years with a total of 9 participants with 4 males and 5 females. It can be observed that in both the groups, the rate of canine retraction at three different time interval was highly significant (p<0.001) but minimal differences was seen between LPRP and MOP groups which was not statistically significant.
CONCLUSION: This study demonstrated that both MOP and LPRP showed accelerated tooth movement over the course of two months ,while the difference between the two groups was not statistically significant. Future studies to further validate these findings with larger sample sizes are recommended.

Abstract
Background: Sagittal jaw discrepancies are a critical determinant in orthodontic diagnosis and treatment planning, necessitating an accurate assessment. This study aims to investigate the predictive efficacy of various sagittal parameters (ANB angle, Wits appraisal, Beta angle, Yen angle, and W angle) in diagnosing skeletal Class I malocclusion across diverse growth patterns.
Materials and Methods: A retrospective cross-sectional analysis was conducted using lateral cephalograms of 60 patients diagnosed with skeletal Class I malocclusion. Sagittal skeletal parameters (ANB angle, Beta angle, Yen angle, W angle, and Wits appraisal) were evaluated across three distinct growth patterns (vertical, horizontal, and average). Mean and standard deviation were calculated for each parameter within each growth pattern. One-way ANOVA with post-hoc Tukey's HSD test was employed for pairwise comparisons between groups. The inter-relationship between cephalometric parameters and growth patterns was assessed using Pearson's correlation coefficient, with statistical significance set at p ≤ 0.05.
Results: A total of 60 participants (30 males and 30 females) with a mean age of 18.60 ± 4.17 years were included in the study. Highly statistically significant differences were noted for Beta and Yen angle (p ≤ 0.001), whereas statistically significant differences were noted for ANB angle. The correlation test revealed a possible association between assessed parameters in the overall sample.
Conclusion: Angular and linear parameters revealed some degree of correlation in skeletal class I malocclusion patients irrespective of their growth pattern. However, the reliability of individual parameters in accurately classifying the skeletal discrepancies among different malocclusion states should be further investigated.

Abstract
Background: It was essential to evaluate respiratory function when diagnosing and planning orthodontic treatment. Based on the correlation between pharyngeal airway space and craniofacial structure, airway width was hypothesized to be an indicator of airway patency in different groups of skeletal malocclusion.
Aim: The purpose of this study was to investigate age and gender related changes in pharyngeal airway dimensions in different sagittal skeletal relationships
Materials and Method: Sixty lateral cephalograms of patients aged 10-30 years with no pharyngeal pathology or nasal obstruction were retrospectively selected and categorized into skeletal Class I (n = 20), Class II (n = 20), and Class III (n = 20) malocclusion based on ANB angle. McNamara's airway analysis was used to quantify upper- and lower-airway dimensions. The analyses of intergroup differences were performed using a one-way ANOVA, an independent t-test, and Tukey's test as a post-hoc test.
Results: Participants in the study ranged in age from 20.57 ± 5.41 years (males) and 20.03 ± 4.58 years (females) were included in the study. The upper pharyngeal airway (UPA) dimensions demonstrated a positive correlation with age. In both genders, the mean upper pharyngeal airway (UPA) size exceeded the lower pharyngeal airway (LPA) size, but neither age nor gender was associated with statistically significant differences in skeletal malocclusion.
Conclusion: It was shown that skeletal malocclusions of different types have no effect on the upper and lower pharyngeal airways and that the upper and lower pharyngeal airways are not influenced by age or gender.
