Objectives: The aim of this study was to estimate the prevalence of dentine hypersensitivity in a sample of patients visiting a general dental practice. Study design: The study population consisted of 1,450 patients, 690 males and 760 females, aged 18-69 years. All individuals were clinically examined and answered questions regarding variables such as gender, age, educational level, occupation ...

The effects of sealing infected carious dentine below dental restorations on the phenotypic and genotypic diversity of the surviving microbiota was investigated. It was hypothesized that the microbiota would be subject to nutrient limitation or nutrient simplification, as it would no longer have access to dietary components or salivary secretion for growth. The available nutrients would be limi...

UNLABELLED Dentine hypersensitivity is a common clinical finding with a wide variation in prevalence values and etiological factors. The objective of this cross-sectional study was to investigate the prevalence and some etiological factors of dentine hypersensitivity of Emirati patients visiting general dental clinics in the United Arab Emirates (UAE) over a period of three calendar months. M...

OBJECTIVE To evaluate the effect of a dentine bonding system to sclerotic dentine in comparison with normal dentine. METHODS The efficacy of the dentine bonding system to sclerotic dentine was examined by measuring wall-to-wall polymerization contraction gap width. The dentine cavity wall was pretreated with an experimental dentine bonding system with and without a dentine primer. The dentine...

AIM Dentine hypersensitivity may be defined as pain arising from exposed dentine typically in response to chemical, thermal or osmotic stimuli that cannot be explained as a rising from any other form of dental defect or pathology. The aim to this cross-sectional study was to determine prevalence of dentine hypersensitivity (DH) and to examine some associated etiological factors in a study of pa...

Dentine hypersensitivity or more colloquially “sensitive teeth” is a common problem encountered in routine clinical practice. The diagnosis of it, at times, is intriguing for even the most experienced clinician. The condition, though not alarming, is important diagnostically and therapeutically because it tends to disturb the routine day to day life of the patient, often becoming troublesome du...

Objectives: The aim of this in vitro study was to investigate the effects of two luting agents and various specimen thicknesses on the bond strength of fibre posts to root canal dentine. Methods: Sixty central incisors were sectioned below the cement enamel junction. Following standardized post-space preparations, the roots were divided into two luting agent groups, and further divided into thr...

AIM To compare the fracture resistance of thin-walled roots after restoration with different types of post systems. METHODOLOGY One hundred and sixty-five decoronated maxillary central incisors were root filled and randomly assigned to three groups with respect to the remaining dentine thickness of root (1.0 mm, 1.5 mm, 2.0 mm). Each group was randomly divided into five equal subgroups. The s...

This study investigated the effect of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP)-modified glass ionomer cement (GIC) on shear bond strength (SBS) and remineralisation of artificial "caries-affected" dentine. Human dentine slices were demineralised and allocated to three groups: group 1, conventional GIC; group 2, CPP-ACP-modified GIC; and group 3, resin-modified GIC. The SBS wa...

In the current study, we evaluate the equivalent stiffness of peritubular reinforcement effect (PRE) of porous dentine optimized by the thickness of peritubular dentine (PTD). Few studies to date have evaluated or quantitated the effect of PRE on composite dentine. The miscrostructure of porous dentine is captured by scanning electron microscope images, and then finite element modeling is used ...
