BACKGROUND Pulsed radiofrequency (PRF) treatment is defined as the delivery of short pulses of radiofrequency via a needle tip, which does not result in an actual thermal lesions. There are mixed views regarding the use of PRF for trigeminal neuralgia (TN). In our opinion, one of the main reasons for the contrasting views is the insufficient PRF dose employed in previous studies. In a recent st...

Abstract Sequences of consecutive Legendre and Jacobi symbols as pseudorandom bit generators were proposed for cryptographic use in 1988. Major interest has been shown towards functions (PRF) recently, based on the power residue symbols, due to their efficiency multi-party setting. The security these PRFs is not known be reducible standard assumptions. In this work, we show that key-recovery at...

BACKGROUND For the treatment of the bisphosphonates and other drugs related osteonecrosis of the jaws, currently medication-related osteonecrosis of the jaws (MRONJ), have been established different conservative therapeutic approaches, avoiding surgery except in cases of extreme need. Given the controversy and lack of current consensus regarding MRONJ therapy in patients, new techniques have be...

PURPOSE The aim of this study was an experimental evaluation of the effectiveness of demineralized bone matrix (DBM) and collagenated heterologous bone graft (CHBG) used alone or in combination with platelet-rich fibrin on bone healing in sinus floor augmentation procedures. MATERIALS AND METHODS In this study, 36 New Zealand rabbits were used. The bilateral sinus elevation was performed, and...

Constrained pseudorandom functions have recently been introduced independently by Boneh and Waters (Asiacrypt’13), Kiayias et al. (CCS’13), and Boyle et al. (PKC’14). In a standard pseudorandom function (PRF) a key K is used to evaluate the PRF on all inputs in the domain. Constrained PRFs additionally offer the functionality to delegate “constrained” keys KS which allow to evaluate the PRF onl...

OBJECTIVE Cervical radicular pain is defined as pain arising in the arm caused by irritation of a cervical spinal nerve or its roots. Although many treatment modalities are described in the literature, the available evidence for efficacy is not sufficient to allow definitive conclusions. The goal of this study was to establish the benefits and prognostic factors of pulsed radiofrequency (PRF) o...

Background: Platelet-rich fibrin (PRF) has regenerative characteristics and is used as an autologous source of growth factors for tissue regeneration wound healing. Objective: Evaluating the efficacy C-PRF increasing gingival thickness (GT) keratinized width (KTW) in subjects with a thin phenotype comparison I-PRF injection. Methods: Ten healthy participants (GT ≤ 1.0 mm) were enrolled this stu...

AIM The purpose of this study was to compare the efficacy of platelet-rich plasma (PRP), platelet-rich fibrin (PRF), and hydroxyapatite (HA) for reduction of pain and swelling, absence of dry socket, soft tissue healing, and bone regeneration after mandibular third molar extraction in human patients. MATERIALS AND METHODS Forty patients requiring extraction of mandibular third molars were ran...

Trigeminal neuralgia (TN) produces incapacitating facial pain that reduces quality of life in patients. Thermal radiofrequency (RF) ablation of gasserian ganglion (GG) is associated with masseter weakness and unpleasant sensations along the distribution of the ablated nerve. Pulsed radiofrequency (PRF) of GG has minimal side effects but literature is inconclusive regarding its benefit in refrac...

Abnormal proliferation of vascular smooth muscle cells (VSMCs) results in intimal thickening of the aorta, which may lead to arteriosclerosis. Therefore, VSMC antiproliferative agents may be efficient in the prevention and treatment of arteriosclerosis. Puerariae radix (PR) is the dried root of Pueraria lobata Ohwi or Pueraria thomsonii Benth. Flavones are the main components of PR and have bee...
