Determination of the structure human plaque will be great benefit in prediction its formation and also effects treatment. However, a problem lies harvesting undisturbed intact samples from volunteers viewing biofilms their natural state. In this study, we used an situ device for vivo generation dental on tooth surfaces subjects. Two devices were placed mouths each eight healthy left to generate biofilm 4 days. Immediately upon removal mouth, intact, imaged by non-invasive technique confocal...
Caries occurs at inaccessible stagnation sites where plaque removal is difficult. Here, the penetration through of protective components, such as fluoride, likely to be crucial in caries inhibition. We hypothesized that topically applied fluoride would readily penetrate deposits. In this study, biofilms generated vivo on natural enamel surfaces were exposed NaF (1000 ppm F − ) for 30 or 120 sec (equivalent toothbrushing) min. Biofilms then sectioned throughout their depth, and content each...
Summary. Four hundred and fifty‐five extracted mandibular incisor 340 mandibuiar pretnolar teeth were radiographed to assess the incidence of twin canals as visualized on radiographs taken in mesio‐distal direction. The ability detect presence these by viewing standard bucco‐lingual direction was then assessed. Using guideline that ‘disappearance or narrowing infers division’ when resulted a failure diagnose one‐third canals.
Limiting infection transmission is central to the safety of all in dentistry, particularly during current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Aerosol-generating procedures (AGPs) are crucial practice dentistry; it imperative understand inherent risks viral dispersion associated with AGPs and efficacy available mitigation strategies. In a dental surgery setting, crown preparation root canal access were performed an air turbine or high-speed contra-angle...
To compare the retention force of individual clasps made from cobalt chromium (CoCr) or new aryl ketone polymer (AKP) material, Ultaire™ AKP, following prolonged fatigue testing along ideal and non-ideal paths removal to assess 3D deformation active passive clasp tips.CoCr AKP were manufactured in their standard, respective processes, digitally scanned prior testing, then cycled 15,000 times over an e.max analogue crown artificial saliva. Retentive load was measured situ, as a function...
The study of plaque biofilms in the oral cavity is difficult as removal inevitably disrupts biofilm integrity precluding kinetic studies involving penetration components and metabolism substrates situ. A method described here which formed vivo under normal (or experimental) conditions using a collection device can be removed from mouth after specified time without physical disturbance to biofilm, permitting site-specific analysis or exposure undisturbed experimental conitions vitro....
Summary This study was undertaken to determine the most effective horizontal beam angulation for diagnosis of twin canals in mandibular incisors. Two hundred extracted incisor teeth, groups four, were aligned form a lower dental arch and radiographed using alignment device at 10° intervals between 0° 50° from both right left sides. Five observers with varying degrees experience asked assess number each four teeth these radiographs. A further radiograph individual tooth taken 90° through...
To examine the efficacy of tetra-sodium EDTA in controlling microbial contamination dental unit water systems (DUWS).Ten units were treated once a week with either 4% or 8% for four two consecutive weeks, respectively. Before treatment, 43% and 60% samples from air/water triple syringe high-speed hand-pieces, respectively, exceeded American Dental Association (ADA) guidelines 200 CFU ml(-1) during 6-week baseline period. After each weekend levels all DUWS fell significantly (P < 0.001) to...
Data from countries that have implemented a complete phase out of dental amalgam following the Minamata agreement suggest increased costs and time related to placement alternatives with consumers absorbing additional costs. This aim this study was investigate impact on oral health inequalities in particular for dependent state run services.A mixed methods component design quantitative qualitative United Kingdom. The involved acquisition analysis datasets NHS Scotland compare trends survey...
Facial prostheses can have a profound impact on patients' appearance, function and quality of life. There has been increasing interest in the digital manufacturing facial which may offer many benefits to patients healthcare services compared with conventional processes. Most prosthesis research adopted observational study designs very few randomised controlled trials (RCTs) documented. is clear need for well-designed RCT compare clinical cost-effectiveness digitally manufactured versus...
This paper reports the first attempts to implement a new course in endodontology for undergraduate dental students based upon independent, reflective learning and self-assessment.The responses were analysed of two successive cohorts third-year laboratory courses (i) restoration teeth with crowns (ii) root canal treatment. The major changes introduced substantial reduction number formal lectures, introduction series structured tutorials, time private study use self-assessment practical...
The first part of this series on the conventional rehabilitation oncology patients with hard palate defects discussed dental challenges posed by and surgical/restorative planning interface for rehabilitation. This article will describe Aramany's classification defects, Brown's palatal focus basic principles obturator design which need to be appreciated when prosthetically rehabilitating a patient defect. CPD/CLINICAL RELEVANCE: A good understanding removable prosthodontic theory relating...
This study assessed the impact of increased speed high-speed contra-angle handpieces (HSCAHs) on aerosolization a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) surrogate virus and any concomitant thermal dental pulp. A bacteriophage phantom-head model was used for bioaerosol detection. Crown preparations were performed with an NSK Z95L Contra-Angle 1:5 (HSCAH-A) Bien Air Nova Micro Series (HSCAH-B) at speeds 60,000, 100,000, 200,000 revolutions per minute (rpm), no air...
