π-Stacked polymers in drug delivery applications
2016
Abstract Polybenzofulvenes are π-stacked polymers, which can be synthesized by spontaneous polymerization of the corresponding monomers without the use of catalysts or initiators. Therefore, they can be obtained completely free from byproducts, impurities, or harmful substances. The absence of any relevant toxic effects and cell viability impairments allows PEGylated polybenzofulvene brushes to be potentially functional in a wide range of biological, biomedical, and biotechnological applications. Moreover, the properties of these polymers, in terms of interaction with pharmacological active agents and the ability to self-assemble into nanoaggregates or a quite compact physical gel useful as…
Influence of lifestyle on oral health behavior among rural residents of Udaipur district, India
2010
Objectives: To determine the relation of life style with dental health behavior such as tooth brushing frequency, use of extra cleansing devices and regular visits to dentist among rural residents of Udaipur district, India. Study design: The study population comprised of 1001 rural population between the ages 18 to 69 years selected by multi stage stratified cluster sampling procedure. Personal interviews were conducted by three trained interviewers who collected information on socio-demographic and lifestyle factors in addition to some aspects of dental health behavior including tooth brushing frequency, use of extra cleaning devices like dental floss and regular visits to dentist. Result…
Local Gingival Blood Flow at Healthy and Inflamed Sites Measured by Laser Doppler Flowmetry
2006
This investigation aimed to: 1) develop a method to obtain reproducible laser Doppler flow readings (LDFRs) at the gingiva of the maxillary front teeth; 2) evaluate regional gingival blood flow (GBF) in healthy gingiva by laser Doppler flowmetry; 3) compare hand-held LDFR (H-LDFR) with splint LDFR (S-LDFR); and 4) monitor changes in GBF in experimental gingivitis (EG) and chronic gingivitis (CG).The LDFR, gingival index (GI), and plaque index (PI) were measured at 13 gingival sites (teeth #6 to #11) in 10 healthy volunteers (five males and five females), 23 to 34 years of age, over a period of 12.5 +/- 3.27 days employing a partial-mouth EG model and in 11 patients (three males and eight fe…
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 …
Streptococcal bacteraemia in patients submitted to hematopoietic stem cell transplantation: the role of tooth brushing and use of chlorhexidine.
2009
A retrospective evaluation of 73 consecutive recipients of hematopoietic stem cell transplantation (HSCT) was conducted to investigated the role of oral care and incidence of streptococcal bacteremia in patients submitted to hematopoietic stem cell transplantation. Patients were retrospectively evaluated and divided into group A (GA=38) and group B (GB=35). During hospitalization patients from GA performed oral hygiene daily with extra soft toothbrush and toothpaste besides performing mouth cleaning with an ethanol-free 0.12% chlorhexidine solution tree times a day. In contrast GB patients performed mouth cleaning with extra soft toothbrush and toothpaste, but no chlorhexidine was used. Usi…
Effectiveness of a miswak extract-containing toothpaste on gingival inflammation: a randomized clinical trial.
2015
Objectives In this study, the efficacy of a miswak extract-containing toothpaste (Salvadora persica) on gingival inflammation was compared with that of a herbal and a conventional toothpaste. Methods Non-smoking outpatients with sulcus bleeding index (SBI) ≥25% and with periodontal pocket depths ≤3 mm were randomly selected and divided into three groups: M-group, miswak extract-containing toothpaste; P-group, herbal toothpaste; and C-group, conventional toothpaste. After instructing the patients to brush their teeth twice a day for 3 weeks with the assigned toothpaste using a flat-trimmed manual toothbrush, a thorough oral examination was performed by a calibrated examiner (EH). The primary…
Evaluation of the diagnostic value of a Modified Liquid-Based Cytology using OralCDx Brush in early detection of oral potentially malignant lesions a…
2009
Objectives: To determine diagnostic value of modified Liquid Based Brush Biopsy technique. Study design: 26 oral premalignant and malignant lesions in 25 patients (12 females; 54.23±19.77 years and 13 males; 53.77±15.43 years) underwent Modified (Liquid Based) Brush Biopsy and scalpel biopsy simultaneously from the same area. Results: There were 16 positive and 10 negative brush biopsy results, with no inadequate readings. Histological findings were compatible with oral leukoplakia(n=5)with dysplasia, Oral lichen planus and lichenoid reaction(n=7) (with or without dysplasia)oral squamous cell carcinoma(n=11),verrucous carcinoma(n=1) and granular cell tumors( n=2). Sensitivity, specificity, …
Root caries analysis in working population of 35-44 years of age (Spain)

A swallowed toothbrush
2001
A 27-year-old woman came to the emergency department in April, 1999, after swallowing a toothbrush while cleaning her teeth 1 hour previously. She attributed the accident to clumsiness which made her slip on the wet bathroom floor, thereby forcing the toothbrush deep into her throat She reported no other illnesses. She had no pain, dysphagia, or dyspnoea. On examination she had a normal weight (body mass index of 22 kg/m). Her oropharnyx had no signs of injury and the rest of the physical examination was normal. A chest radiograph showed a toothbrush projecting towards the distal oesophagus with the head pointing to the oropharynx (figure), a finding which was not compatible with the report…
