The aim of this retrospective study was to evaluate the periodontal therapy performed in the undergraduate curriculum (master level) at the School of Dental Medicine at the University of Basle, Basle, Switzerland. Patients diagnosed with advanced chronic or aggressive periodontitis were included in the study, provided that they were ≤40 years of age at the initial examination and had undergone ...

Dear Editor Shimazaki et al. analyzed oral health examination findings for 4,484 male and female employees aged 35 to 74 in relation to past participation in oral health examinations reported in a questionnaire1) and concluded that workplace oral health examination accompanied by oral health instruction may be effective for maintenance of periodontal health. We think this is an important public...

BACKGROUND The purpose of this study was to conduct an in vitro and short-term clinical and microbiological evaluation of a linear oscillating device for scaling and root planing (SRP). A comparison was made between conventional ultrasonic scaling (US) and hand scaling (HS) with and without chlorhexidine. METHODS In vitro, SRP was carried out on human teeth with calculus. Roots and cross-sect...

BACKGROUND Enamel matrix derivative (EMD) is a composite of proteins that was demonstrated histologically to work as an adjunct to periodontal regenerative surgical therapy. The purpose of this study was to evaluate the clinical and histologic effects of EMD as an adjunct to scaling and root planing. METHODS Four patients with severe chronic periodontitis and scheduled to receive complete den...

OBJECTIVES This study aimed to compare the efficacy of MTA and CEM cement in Class II furcation defects in human mandibular molars. MATERIALS AND METHODS Forty furcation defects were treated in 16 patients with chronic periodontitis. The clinical parameters of probing depth (PD), vertical and horizontal clinical attachment levels (VCAL and HCAL), open vertical and horizontal furcation depths ...

Periodontal disease, commonly known as gum disease, affects millions of Americans. The current method of detecting periodontal disease is painful, invasive, and inaccurate. As an alternative to manual probing, the ultrasonographic periodontal probe is being developed to use RF ultrasound waveforms to measure periodontal pocket depth, which is the main measure of periodontal disease. The methods...

Correlations between magnetic reconnection and energetic ion flow events have been measured with merging force free spheromaks at the Swarthmore Spheromak Experiment. The reconnection layer is measured with a linear probe array and ion flow is directly measured with a retarding grid energy analyzer. Flow has been measured both in the plane of the reconnection layer and out of the plane. The mos...

AIM The purpose of the present in vitro study was to measure the accuracy and reproducibility of three periodontal probes. To eliminate environment- or examiner-related probing errors, two aluminum blocks with predrilled holes of varying depths were examined by participants who had been trained in probing before the study. This methodology improved the likelihood that any probing errors identif...

Chronic renal failure is a progressive disease caused by the damage of the functional unit of the kidney, the nephron. Periodontal diseases are common among renal failure patients; however this relationship is not clearly understood. The aim of this study was to evaluate the oral hygiene habits and its impact on periodontal status in end stage renal disease (ESRD) patients. Eighty ESRD patients...

The Southern Ocean is anomalously rich in benthos. This biodiversity is native, mostly endemic and perceived to be uniquely threatened from climateand anthropogenicallymediated invasions. Major international scientific effort throughout the last decade has revealed more connectivity than expected between fauna north and south of the worlds strongest marine barrier—the Polar Front (the strongest...
