Comparison of success rate and onset time of two different anesthesia techniques
2014
Background: Using local anesthetic is common to control the pain through blocking the nerve reversibly in dental procedures. Gow-Gates (GG) technique has a high success rate but less common. This study aimed to compare the onset time and success rate in GG and standard technique of inferior alveolar nerve block (IANB). Material and Methods: This descriptive, single blind study was consisted of 136 patients (59 males and 77 females) who were randomly received GG or IANB for extraction of mandibular molar teeth. Comparisons between the successes of two anesthetic injection techniques were analyzed with Chi-square test. Incidence of pulpal anesthesia and soft tissue anesthesia were analyzed wi…
rTMS of the prefrontal cortex in the treatment of chronic migraine: a pilot study
2004
A recent fMRI study showed that dorsolateral prefrontal cortex (DLPFC) exerts an inhibitory control on pain pathways in humans. We investigated whether high-frequency rTMS over left DLPFC could ameliorate chronic migraine. Treatment consisted of 12 rTMS sessions, delivered in alternate days over left DLPFC. Sham rTMS was used as placebo. Eleven patients were randomly assigned to the rTMS (n=6) or to the placebo (n=5) treatment. Measures of attack frequency, headache index, number of abortive medications (outcome measures) were recorded in the month before, during and in the month after treatment. Subjects treated by rTMS showed a significant reduction of the outcome measures during and in t…
The effects of sugar-free chewing gums on dental plaque regrowth: a comparative study
2006
Abstract Sugar-free chewing gum has been claimed to be a useful means of reducing dental plaque accumulation. The incorporation of additives, such as enzymes, abrasives and divalent metal ions, into gum formulations might improve their antiplaque activity, particularly at the buccal and lingual surfaces of the teeth. Objectives The aim of this study was to investigate the plaque inhibitory effects of three sugar-free chewing gums each containing lactoperoxidase (LP), micro granules of silicon dioxide (SD), and zinc gluconate (ZG). Methods The study was an observer-masked, randomized cross-over design balanced for carryover effects, involving 12 healthy volunteers in a 4-day plaque regrowth …
Olive oils high in phenolic compounds modulate oxidative/antioxidative status in men
2004
The aim of the present study was to evaluate whether olive oils high in phenolic compounds influence the oxidative/antioxidative status in humans. Healthy men (n = 12) participated in a double-blind, randomized, crossover study in which 3 olive oils with low (LPC), moderate (MPC), and high (HPC) phenolic content were given as raw doses (25 mL/d) for 4 consecutive days preceded by 10-d washout periods. Volunteers followed a strict very low-antioxidant diet the 3 d before and during the intervention periods. Short-term consumption of olive oils decreased plasma oxidized LDL (oxLDL), 8-oxo-dG in mitochondrial DNA and urine, malondialdehyde in urine (P < 0.05 for linear trend), and increased HD…
Conventional and spectral power analysis of all-night sleep EEG after subchronic treatment with paroxetine in healthy male volunteers.
1998
Paroxetine is a selective and potent serotonin reuptake inhibitor with reported antidepressant properties. Since changes in the regular sleeping pattern were described as side effects under treatment with paroxetine, the impact of the drug on the sleep architecture is of major interest. The present study addressed the question of subchronic effects of paroxetine medication (30 mg/day) in eight healthy male volunteers in a double blind, placebo-controlled crossover-design. Conventional sleep EEG parameters and additionally computed spectral power analysis based on FFT of 20-s time epochs in the delta, theta, alpha, beta and gamma frequency range for different sleep stages after 4 weeks of tr…
Contralateral hand anesthesia transiently improves poststroke sensory deficits.
2005
Objective To test a possible strategy to alleviate somatosensory deficits after stroke. Methods Here, we applied ischemic nerve block to the intact hand of patients with chronic stroke, which in healthy subjects elicits improvements in sensibility of the other hand. Results We found that sensibility in the affected hand improved with intact hand anesthesia, but not with intact foot anesthesia or no anesthesia. Interpretation We conclude that reduction of sensory input from the intact hand leads to site-specific improvements in tactile discriminative skills in the affected hand after the period of anesthesia, a potentially relevant finding in designing neurorehabilitative interventions. Ann …
Effect of non-surgical periodontal treatment with or without doxycycline on the periodontium of type 1 diabetic patients
2005
Aim: The present investigation was performed to study how type 1 diabetics responded to non-surgical periodontal treatment with and without adjunctive doxycycline. Method: Sixty diabetic type 1 patients (mean age 35.3 +/- 9 years) with moderate-to-severe periodontal disease were selected and divided into two groups of 30 patients each. Both groups were sex and age matched and had similar amounts of periodontal destruction. Plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment levels (CAL) were recorded. Group 1 (30 patients) was treated with oral hygiene instruction, scaling and root planing, chlorhexidine rinses twice a day and doxycycline (100 mg/day for…
Effect of EDTA root conditioning on the healing of intrabony defects treated with an enamel matrix protein derivative.
2006
Contains fulltext : 49580.pdf (Publisher’s version ) (Open Access) BACKGROUND: Regenerative periodontal therapy with an enamel matrix protein derivative (EMD) has been shown to promote regeneration in intrabony periodontal defects. However, in most clinical studies, root surface conditioning with EDTA was performed in conjunction with the application of EMD, and, therefore, it cannot be excluded that the results may also be attributable to the effect of the root conditioning procedure. The purpose of this study was to determine the effect of root conditioning on the healing of intrabony defects treated with EMD. METHODS: Twenty-four patients, each of whom exhibited one deep intrabony defect…
Plaque removal efficacy of power and manual toothbrushes: a comparative study
2009
The aim of this study was to compare the plaque removal efficacy of a new oscillating/rotating/pulsating toothbrush [Oral-B® Professional Care® 8500 (PC 8500)] with two manual toothbrushes [Oral-B® CrossAction™ Vitalizer (CAV) and Oral-B® Indicator™ (IND), respectively]. The safety of the PC 8500 was also assessed. The study was a single-use, observer-masked, randomised 3×3 Latin square crossover design balanced for carryover effects. The enrolled subjects (n=66) refrained from brushing for 23–25 h before each clinical examination. Plaque scores were recorded before and after brushing with the allocated toothbrush using the Turesky et al. modification of the Quigley and Hein plaque index. T…
Efficacy of 3 toothbrush treatments on plaque removal in orthodontic patients assessed with digital plaque imaging: a randomized controlled trial.
2013
Good oral hygiene is a challenge for orthodontic patients because food readily becomes trapped around the brackets and under the archwires, and appliances are an obstruction to mechanical brushing. The purpose of this study was to compare plaque removal efficacy of 3 toothbrush treatments in orthodontic subjects.This was a replicate-use, single-brushing, 3-treatment, examiner-blind, randomized, 6-period crossover study with washout periods of approximately 24 hours between visits. Forty-six adolescent and young adult patients with fixed orthodontics from a university clinic in Germany were randomized, based on computer-generated randomization, to 1 of 3 treatments: (1) oscillating-rotating …
