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

Aim: To compare the rate and efficiency of Niobium-Titanium-Tantalum Zirconium archwire (Gummetal), Copper Nickel Titanium archwire (CuNiTi) and conventional nickel titanium archwire (NiTi) on initial alignment.

Materials And Methods: A single-center randomized controlled clinical trial was conducted in 33 fully erupted dentition patients and Little’s Irregularity Index (LII) >2 mm. Patients were randomly assigned to three groups (n=11 each) treated with 0.014-inch NiTi, CuNiTi, or Gummetal archwires. Impressions were taken at baseline (T0) and at 3-week intervals for 4 times (T1–T4). LII, Intercanine width (ICW) and intermolar width (IMW) were measured and analyzed using SPSS v20.0 with Repeated Measures ANOVA, Bonferroni post-hoc, and Chi-square tests with p value <0.05 as statistical significance.

Results: All groups showed statistically significant reduction in LII from T0 to T4 (p<0.001). Group 1 showed a decrease from 3.76±0.75 to 1.02±0.53, Group 2 from 3.74±0.64 to 0.90±0.25, and Group 3 from 3.04±0.59 to 1.33±0.66. ICW increased significantly in all groups: Group 1 from 25.93±2.86 to 26.58±2.78 (p<0.001), Group 2 from 25.59±2.68 to 26.64±2.76 (p < 0.001), and Group 3 from 25.79±2.86 to 26.52±2.83 (p=0.008). IMW changes were significant in Group 2 (40.76±2.66 to 41.11±2.63, p<0.001) and Group 3 (40.95±2.61 to 41.11±2.63, p<0.001), but not in Group 1 (41.01±2.64 to 41.08±2.62, p=0.136). Intergroup comparison revealed no statistically significant difference in LII, ICW, or IMW (p≥0.051).

Conclusions: CuNiTi and NiTi archwires were more effective in initial alignment and mild arch expansion than Gummetal, making them preferable for early orthodontic correction.

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.
