ABSTRACT

OBJECTIVE: To determine the effects of the local administration of injectable Platelet-Rich Fibrin on the rate of canine retraction.

METHODS: This split-mouth trial included 10 subjects who underwent canine retraction aided with injectable PRF (i-PRF) injected into the buccal, distal, and palatal intraligamentary sites of the canine on the intervention side, with saline administered as a control on the contralateral side every 30 days. Canine retraction was initiated by applying 150 grams of force, and intraoral scans were taken every 30 days for 90 days and assessed for canine retraction. Pain perception was assessed with Visual analog scale. Statistical analysis was conducted, with significance set at p < 0.05.

 RESULTS: Statistically significant higher canine retraction was observed after administering I-PRF in the first month compared to control side (p=0.012), and significantly less canine retraction was observed in the second month (p=0.036) in I-PRF side and no significant difference by the third month. Pain scores were higher in the I-PRF group after 24 hours (p=0.007) but lower after one week (p=0.011).

CONCLUSION: The results of this clinical trial indicate that there is no statistically significant difference in canine retraction between i-PRF and control.

Abstract

White Spot Lesions (WSLs) are early signs of enamel demineralization, often occurring during orthodontic treatment due to hindered oral hygiene maintenance. Traditional treatment methods include resin infiltration or remineralization using fluoride-based agents. However, self-assembling peptides (SAPs), such as Curodont ™ Repair (P11-4), have emerged as potential alternatives for WSL management. This review comprehensively examines the chemistry, mode of action, clinical safety, and efficacy of SAP P11-4 in remineralizing enamel lesions. It synthesizes findings from studies investigating SAP P11-4's remineralizing potential using various assessment methods, including pH cycling models, laser fluorescence, digital subtraction radiography, and confocal microscopy. SAP P11-4, with its ability to mimic the enamel matrix and promote hydroxyapatite nucleation, demonstrates promising outcomes in reducing WSL size and progression. Clinical studies report significant improvements in lesion remineralization with SAP P11-4 treatment, often surpassing the efficacy of fluoride-based interventions. Moreover, SAP P11-4 shows compatibility with bonding procedures and potential for reducing dentin hypersensitivity. They offer a promising alternative or adjunct to traditional fluoride-based treatments for WSL management, providing clinicians with a valuable tool in promoting enamel health and preventing caries progression. Further research is warranted to explore long-term outcomes and optimize treatment protocols for maximum efficacy.
