Resonance frequency analysis (RFA) provides an evaluation of implant stability over time. This analysis is a non-invasive, precise, and objective method. Several studies compare the RFA system with other devices. However, few investigations analyze repeatability and reproducibility between different operators. The aim of this study was to evaluate the intra- and inter-operator concordance of the Osstell® ISQ.RFA measurements were performed with Osstell® ISQ in a total of 37 implants placed in 21 patients. At the time of implant placement, 6 measurements per implant were taken by three different experienced operators. Three measurements were carried out consecutively and three by removing and placing the SmartPeg-Osstell® to assess intra-operator and inter-operator agreement.Intra-operator concordance according to the intraclass correlation coefficient (ICC) showed high concordance. The ICC values were higher than 0.9 (p 0.0001) for consecutive measures and alternative measures, being almost perfect of LandisKoch classification. For inter-operator concordance The ICC was 0.709 (p 0.0001) and 0.670 (p 0.0001) for consecutive and alternative measures, respectively, both estimates being in the substantial category. In torque and ISQ values, no statistically significant differences were observed when operators and measurements were compared.Osstell® ISQ system was stable both in intra-operator and inter-operator measurements. This device has excellent repeatability and reproducibility, demonstrating reliability to measure the stability of dental implants.Resonance frequency analysis (RFA) is a non-invasive, objective, and reliable diagnostic method to determine the ideal moment to load the implant, as well as to predict possible failures.

The objective of this systematic review was to determine the effectiveness of preoperative oral pregabalin for anxiety control, the most effective dosage regimen, its impact on postoperative pain, and its adverse effects. A search was conducted of PubMed/Medline and clinicaltrials.gov (National Library of Medicine, Washington, DC), Scopus, Web of Science, and Cochrane databases for studies published between January 2009 and November 2018, with no language restriction. Based on PRISMA guidelines, the specific question was: is preoperative oral pregabalin effective and safe for anxiety control in patients undergoing surgery? The critical reading of retrieved studies followed questions prepared by the CASPe Network, and their methodological quality was evaluated using the Jadad Scale. Twelve randomized controlled trials were selected for review. All twelve studies were trials of high quality. A dose of 75 mg preoperative oral pregabalin has been found to reduce anxiety and stabilize intraoperative hemodynamics, although a more significant improvement appears to be achieved with a single dose of 150 mg pregabalin at least 1 h before the surgery. It is not associated with any severe adverse effects. Preoperative administration of oral pregabalin in a single dose of 150 mg appears to be effective to significantly reduce the anxiety of patients, intraoperative hemodynamic changes, and postoperative pain. These findings suggest that pregabalin is useful and safe for preoperative and intraoperative anxiety control in patients undergoing surgery.

The objectives of this systematic review were to unify criteria on the effectiveness of oral pregabalin to treat acute post-operative pain after cervicofacial surgery, to establish the most effective dose regimens, and to determine its effect on rescue medicine consumption and its association with adverse effects. PubMed/Medline (National Library of Medicine, Washington, DC), Scopus, Web of Science, and Cochrane databases were searched for studies in any language published between January 2000 and September 2016. The following question was posed, in accordance with PRISMA guidelines: Is oral pregabalin effective and safe for the relief of acute pain after cervicofacial surgery? The critical reading of the literature utilized a list of questions prepared by the CASPe Network, applying the Jadad scale for evaluation of the methodological quality of trials. Eleven randomized controlled clinical trials were selected. The 11 trials obtained a score ≥ 3, considered as Ib evidence level and high quality. A single oral dose of 75-mg pregabalin before or after cervicofacial surgery alleviates pain and lessens the need for rescue analgesia consumption, while the statistical significance of these effects is higher with a single dose of 150-mg pregabalin, either before or after the surgery. Oral pregabalin appears to significantly alleviate post-operative pain and reduce rescue analgesia consumption, with no severe adverse effects. However, the ideal dose and most effective administration regimen remain controversial issues that need to be addressed in further high-quality clinical trials. These findings suggest that pregabalin may be useful for acute pain relief after cervicofacial surgery.

The aim of this randomized controlled clinical trial was to evaluate the efficacy and safety of pregabalin administered pre- and postoperatively in patients with pain and swelling due to the surgical removal of impacted lower third molars. The final study sample comprised 60 volunteers (23 males and 37 females). Group 1 (n = 30) received 75 mg oral pregabalin 1 h before surgery and 1 h after surgery. Group 2 (n = 30) served as a control group and received no pregabalin. Both groups were administered with 650 mg paracetamol every 8 h for 2 days. Postoperative pain intensity and swelling were measured using a visual analog scale (VAS); pain relief experienced was reported using a four-point verbal rating scale (VRS); the rescue medication requirement, adverse effects, and global impression of the medication were also recorded. No significant difference in pain intensity (VAS) was observed between the groups. However, fewer rescue medication tablets were needed by pregabalin-treated patients than by controls (p = 0.021). The frequency and intensity of adverse effects were significantly higher in pregabalin-treated patients (p

The objective of this randomized controlled clinical trial (RCT) was to compare the effect of bupivacaine and articaine at habitual doses on pain intensity and the need for analgesics after lower third molar extraction. The final study sample comprised 50 Caucasian volunteers (26 males and 24 females; age range, 18–30 years) undergoing scheduled surgical extraction of impacted lower third molar. A computer-generated random sequence was used to allocate participants to the articaine (4%) or bupivacaine (0.5%) group. Surgeons and patients were blinded by labeling the articaine and bupivacaine carpules with numbers (1 and 2, respectively). Postoperative pain intensity (primary outcome) was evaluated with a visual analogue scale (VAS), while the requirement for and timing of rescue medication and the quality of intraoperative anesthesia were also measured (secondary outcomes). VAS-measured pain intensity was significantly higher (p
