Doxycycline-Loaded β-Tricalcium Phosphate Release Following EDTA Root Surface Etching Improved the Clinical Outcomes in Chronic Periodontitis: An In Vivo Study
چکیده:   (1900 مشاهده)

 Background: The main objective of the present study is to quantify doxycycline (DOX) release from β-tricalcium phosphate (β-TCP) after EDTA root surface treatment.

  Methods: Thirty systemically healthy patients with ≥1 paired contralateral interproximal intrabony defect ≥4 mm deep along with an interproximal probing depth ≥6 mm and clinical attachment level ≥4 mm were randomized into two groups. Group 1 (G1) consisted of sites treated with open flap debridement followed by placement of DOX blended with β-TCP (DOX-β-TCP), whereas group 2 (G2) sites were treated with flap surgery followed by the placement of DOX blended with β-TCP after EDTA etching of the exposed root surfaces (DOX-β-TCP + EDTA). Samples of gingival crevicular fluid (GCF) were obtained 1, 3, 7, 14, and 21 days after surgery. Quantitative measurements of DOX were taken with high-performance liquid chromatography. Clinical evaluation and follow-up for 6 months were performed.

 Results: At 21 days, the DOX-β-TCP + EDTA–treated group showed a 194.7 µg/mL value. The DOX-β-TCP + EDTA–treated group retained more DOX during the periods of 3, 7, 10, 14, and 21 days than the DOX-β-TCP–treated group. Six months after therapy, DOX-β-TCP + EDTA–treated sites showed more significant clinical improvements compared to DOX-β-TCP–treated sites (P ≤ 0.05).

 Conclusions: EDTA root surface etching enhances DOX availability in the GCF following its release from β-TCP as a drug carrier.
