Objectives:  Most dental schools have included dentin hypersensitivity (DH) as part of their taught curriculum to educate undergraduates; however, it is possible that the public still does not recognize its symptoms and the factors that predispose to the onset of this condition. Thus, the aim of this study was to assess the knowledge of a Brazilian population regarding the prevention and treatment of DH and to identify what self-reported factors can serve as predictors of the frequency of DH.

Materials And Methods:  An online questionnaire investigated the demographic characteristics, oral health self-perception and attitudes, and DH prevention and treatment measures of 226 participants.

Unlabelled: The aim of the study was to determine the prevalence of moderate to severe periodontitis in 18-19th century skulls in the St Bride's Lower Churchyard in London, UK.

Materials And Methods: A total of 105 adult skulls (66 M: F 39) from the Museum of London collection were examined for evidence of dental disease. The primary method was to measure the presence of moderate to severe periodontitis.

Background And Objective: Oral malodour is often observed in gingivitis and chronic periodontitis patients, and the tongue microbiota is thought to play a major role in malodorous gas production, including volatile sulphur compounds (VSCs) such as hydrogen sulphide (H S) and methanethiol (CH SH). This study aimed to examine the link between the presence of VSCs in mouth air (as a marker of oral malodour) and the oral bacterial ecology in the tongue and periodontal niches of healthy, gingivitis and periodontitis patients.

Methods: Participants were clinically assessed using plaque index, bleeding on probing (BOP) and periodontal probing depths, and VSC concentrations in their oral cavity measured using a portable gas chromatograph.

Objective: This study aims to incorporate 2:1 MgAl and 2:1 CaAl layered double hydroxides (LDHs) in experimental dental-composites to render them fluoride rechargeable. The effect of LDH on fluoride absorption and release, and their physico-mechanical properties are investigated.

Methods: 2:1 CaAl and 2:1 MgAl LDH-composite discs prepared with 0, 10 and 30wt% LDH were charged with fluoride (48h) and transferred to deionized water (DW)/artificial saliva (AS).

This systematic review appraises studies conducted with layered double hydroxides (LDHs) for fluoride release in dentistry. LDH has been used as antacids, water purification in removing excess fluoride in drinking water and drug delivery. It has great potential for controlled fluoride release in dentistry, e.

Motivational Interviewing has been demonstrated to be effective for a wide range of health behaviors. It is an effective behavior change method, which can be utilized in the dental practice setting. It can be used as a brief intervention to increase motivation to improve patients' oral hygiene behaviors as well as providing a framework for delivering diet, smoking cessation, oral health changes, and alcohol advice.

There are numerous over-the-counter (OTC) and professionally applied (in-office) products and techniques currently available for the treatment of dentine hypersensitivity (DH), but more recently, the use of bioactive glasses in toothpaste formulations have been advocated as a possible solution to managing DH. . The aim of the present study, therefore, was to compare several bioactive glass formulations to investigate their effectiveness in an established in vitro model.

The aim of this review is to update dental professionals on the issues and challenges associated with the clinical management of dentine hypersensitivity (DH) and to provide simple guidelines based on presenting clinical features that may help them successfully manage the condition in their day-to-day clinical practice. Details on the management of DH have been previously published in Dental Update which indicated that there was a need for such guidelines. The authors of these guidelines also suggested that, despite the various published clinical studies, there does not currently appear to be one ideal desensitizing agent that can be recommended for treating DH.

The purpose of this overview was to review the available literature to determine if there was any evidence that the application of 10% and 15% carbamide peroxide in tooth whitening procedures resulted in tooth (dentine) sensitivity. The conclusions from the review would indicate that tooth whitening with either 10% or 15% carbamide peroxide is an effective and safe treatment when under a dental professionals' supervision. Reported side-effects were considered mild to moderate in nature and were transient in duration.

Purpose: To determine the abrasivity of a 45S5 bioactive glass based toothpaste on enamel as a function of the particle size and shape of the glass.

Methods: 45S5 glass was synthesized ground and sieved to give various particle sized fractions < 38, 38-63 and 63-110 microns. Two different grinding routes were used: percussion milling and ball milling.

Periodontal probes are the main instruments that are used to assess the status of the periodontium, either for screening purposes or to evaluate periodontal changes throughout the treatment process. With increased knowledge and understanding of periodontal disease, the probes have evolved from a unidimensional manual shape into a more sophisticated computerised instrument. This is due to the need to increase the accuracy and reproducibility of readings and to improve efficiency (time, effort, money).

Objectives: The aim of this overview is to consider the problems that may be associated with making a diagnosis of dentin hypersensitivity (DHS) and to provide a basis for clinicians to effectively diagnose and manage this troublesome clinical condition.

Materials And Methods: A PUBMED literature research was conducted by the author using the following MESH terms: ('diagnosis'[Subheading] OR 'diagnosis'[All Fields] OR 'diagnosis'[MeSH Terms]) AND ('therapy'[Subheading] OR 'therapy'[All Fields] OR 'treatment'[All Fields] OR 'therapeutics'[MeSH Terms] OR 'therapeutics'[All Fields]) AND ('dentin Sensitivity'[MeSH Terms] OR ('dentin'[All Fields] AND 'sensitivity'[All Fields]) OR 'dentin sensitivity'[All Fields]). Variations to the above MeSH terms using terms such as 'cervical', 'dentine' and 'hypersensitivity' as substitutes were also explored, but these searches failed to add any further information.

Objective: Dentin hypersensitivity (DH) is a commonly occurring dental condition, and bioactive glasses (BG) are used in dentifrice formulations for treating DH by forming a surface layer of hydroxycarbonate apatite (HCA) on the tooth, thereby occluding exposed dentinal tubules. Fluoride-containing BG, however, form fluorapatite, which is more stable toward acid attack, and provide a more sustainable option for treating DH.

Methods: Melt-derived multi-component BG (SiO(2)-P(2)O(5)-CaO-CaF(2)-SrO-SrF(2)-ZnO-Na(2)O-K(2)O) with increasing CaF(2)+SrF(2) content (0-32.

Aim: From a review of the literature it is evident that the importance and maintenance of oral health for patients with cancer is recognised as an integral part of basic nursing care and yet from practical observation in the hospital environment together with reviewing the published literature it is clear that there appears to be limited evidence of regular assessment of the mouth or implementation of oral protocols on the ward. Furthermore there is a lack of adequate training in the assessment and implementation of mouth care by nurses during their general nurse training. The aim of the present study was to review existing literature published between 1995 and 1999 to determine whether mouth care was effectively assessed and implemented in the palliative care setting.

Objectives: The aim of this study was to evaluate the variation of fluid filtration across dentin treated with different formulations of potassium oxalate gels and one gel of acidified sodium fluorophosphate, under five different pre-conditioned dentin surfaces.

Methods: The methodology used for the measurement of hydraulic conductance of dentin in the present study was based on the model suggested by Pashley, Stewart and Galloway [Arch Oral Biol 29 (1984)379]. Two hundred dentin discs 1 mm in thickness, obtained from human extracted third molars, were divided into 20 groups of ten specimens each.
