Effects of orthodontic forces on bone turnover biomarkers in peri-miniscrew crevicular fluid: A systematic review.

Int Orthod 2020 Sep 22;18(3):403-411. Epub 2020 Apr 22.

Aristotle University of Thessaloniki, Department of Preventive Dentistry, Periodontology and Implant Biology, Thessaloniki, Greece.

Objective: Peri-miniscrew crevicular fluid (PMCF) analysis of biomarkers representing bone formation or resorption could provide a non-invasive way to monitor bone turnover around miniscrews and the response to force loading. Our objective was to systematically investigate the relevant available evidence.

Materials And Methods: Search without restrictions in eight databases and hand searching until March 2020 took place. Read More

Comparison of BALP, CTX-I, and IL-4 levels around miniscrew implants during orthodontic tooth movement between two different amounts of force.

Angle Orthod 2019 07 7;89(4):630-636. Epub 2019 Feb 7.

Objectives: To evaluate the Interleukin-4 (IL-4), bone-specific alkaline phosphatase (BALP), and C-telopeptide of type I collagen (CTX-I) levels in peri-miniscrew crevicular fluid (PMCF) during orthodontic tooth movement between 75 and 150 g of distalization force.

Materials And Methods: Thirty miniscrews were placed bilaterally between the maxillary second premolars and first molars. The right and the left maxillary canines were moved distally using either 75 or 150 g of force. Read More

A study of interleukin 1β levels in peri-miniscrew crevicular fluid (PMCF).

Prog Orthod 2014 Apr 1;15(1):30. Epub 2014 Apr 1.

Division of Orthodontics and Dentofacial Deformities, Centre for Dental Education and Research, All India Institute of Medical Sciences, New Delhi 110029, India.

Background: This study provides a vital insight in assessing the clinical and biochemical changes in interleukin (IL)-1β levels in peri-miniscrew crevicular fluid (PMCF) during the course of orthodontic tooth movement.

Methods: The study comprised the analysis of IL-1β in peri-miniscrew crevicular fluid obtained from crevices around the miniscrews inserted in 11 patients (eight females and three males, mean age 17.3 ± 4. Read More

Division of Basic Medical Sciences, Faculty of Medicine, Memorial University of Newfoundland, Health Sciences Centre, St John's, Canada.

The effects of two vasoactive agents (adenosine A2A agonist, CGS 21680, and adrenoceptor agonist, noradrenaline) were examined on cardiac output (CO), heart rate (HR), blood pressure (BP), mean circulatory filling pressure (Pmcf), resistance to venous return, arterial resistance, dP/dt, plasma levels of NO2-/NO3-, and inducible nitric oxide synthase (iNOS) activity in lungs ex vivo, following treatment with tumour necrosis factor-alpha (TNF-alpha; 30 microg/kg) in anaesthetized rats. Treatment with TNF-alpha produced significant reduction in CO (41+/-2%), dP/dt (26+/-3%), BP (26+/-2%) and Pmcf (27+/-4%; n=6; mean+/-SEM), but increased arterial resistance. There were no significant changes in the plasma levels of NO2-/NO3-levels over time following treatment with TNF-alpha, but there was a significant increase (approximately twofold) in the activity of the iNOS in the lungs of animals treated with TNF-alpha.

J Anesth 1993 Apr;7(2):198-205

Department of Anesthesiology, Kyoto Prefectural University of Medicine, Kyoto, Japan.

This study was designed to investigate the effect of vagal afferent stimulation on total vascular compliance (TVC). Rats were anesthetized with sodium pentobarbital and artificially ventilated, TVC was determined together with stressed and unstressed blood volumes by measuring mean circulatory filling pressure (Pmcf) at three different levels of circulating blood volume. Measurements was repeated with the intact vagus, after vagotomy and during stimulation of vagal afferents. Read More
