ABSTRACT  

BACKGROUND: The growing use of clear aligners in orthodontics raises environmental concerns due to inadequate disposal and recycling knowledge among dental professionals. This study evaluates their awareness, attitudes, and practices regarding clear aligner disposal and recycling.

MATERIALS AND METHODS: A cross-sectional study was conducted using an electronic survey created with Google Forms, which was distributed to orthodontists, undergraduate practitioners, and non-orthodontic practitioners who had their postgraduate degree. The questionnaire consisted of 25 closed-ended questions divided into three sections: Knowledge (8 questions), Outlook (10 questions), and Practice (7 questions). The responses obtained were tabulated and then statistically analysed using the Statistical Package for Social Sciences software version 21.0. A P-value less than 0.05 was considered statistically significant.

RESULTS: A total of 384 participants completed the survey. Most of the participants had a lack of proper awareness regarding the disposal practices and recycling of the aligners. Orthodontists demonstrated significantly higher knowledge (6.10 ± 1.80) and outlook (8.22 ± 3.71) scores than practitioners of other specialities (2.79 ± 1.91, 6.09 ± 3.59 for knowledge and outlook, respectively) (P ≤ 0.001). Knowledge regarding aligner disposal and recycling was highly statistically significant between general practitioners with an undergraduate degree, postgraduate degree holders other than orthodontics, and orthodontists (p < 0.001).

CONCLUSION: There is a noticeable gap in the knowledge and practices of dental professionals regarding the proper disposal and recycling of clear aligners. This study demonstrates that heightened awareness among clinicians and patients is key to reducing aligner use's environmental impact.

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.
