Spatial and temporal control is a key advantage for placement and rapid setting of light-activated resin composites. Conventionally, placement of multiple thin layers (<2mm) reduces the effect of light attenuation through highly filled and pigmented materials to increase polymerisation at the base of the restoration. However, and although light curing greater than 2mm thick layers is not an entirely new phenomenon, the desire amongst dental practitioners for even more rapid processing in deep cavities has led to the growing acceptance of so-called "bulk fill" (4-6mm thick) resin composites that are irradiated for 10-20s in daily clinical practice...

Dentistry is recognised as a stressful profession. A number of studies focusing on undergraduate education have shown high levels of stress in dental students. However, despite calls to do so, little has been published on methods to teach future dental professionals about stress and how to manage it on a personal level. Psychological stress which is uncontrolled may have an effect on general health. It is recognised, however, that stress can be beneficial if channelled appropriately. Techniques and ways to teach management of potential stresses of a career in dentistry have still not been widely reported in either dental undergraduate or postgraduate education...

Malocclusion is a worldwide dental problem that influences the affected individuals to varying degrees. Many factors contribute to the anomaly in dentition, including hereditary and environmental aspects. Dental caries, pulpal and periapical lesions, dental trauma, abnormality of development, and oral habits are most common dental diseases in children that strongly relate to malocclusion. Management of oral health in the early childhood stage is carried out in clinic work of pediatric dentistry to minimize the unwanted effect of these diseases on dentition...

Hemophilia-a bleeding disorder due to the lack of clotting factors-is mostly induced by genetic factors. Its most common type is hemophilia A. Hemorrhage in hemophilia A may occur in several different sites of the body, including those inside the oral cavity, such as mucous membrane and gum. However, only a few studies and case reports on dental issues of hemophilia A patients have been conducted. In clinical dentistry, treatment procedures are invasive, possibly leading to more severe bleeding, especially in hemophilia A cases...

In dentistry, methods for determining age and the degree of dental and skeletal development play an important role, in particular in the assessment of developmental disorders of the dentition as well as in the planning of orthodontic interventions. Dentistry is also important in the field of forensics due to the possibility of age determination based on the dentition. In addition to anthropometric and morphologic methods, numerous biochemical, histologic, radiologic, and radiation-free imaging methods exist to determine the chronologic, but also dental and skeletal age of a person or a patient...

Dental implantology is one of the most attractive and dynamic fields of work within clinical dentistry. It provides many patients with new and improved opportunities for stable (implant-supported) rehabilitation and also offers dentists a field that is interesting in both technical and economic terms. Adverse clinical outcomes are, however, often the subject of discussion. These relate both to prosthetic failure and to biologic complications and side effects, namely persistent infections surrounding implants...

OBJECTIVE: Homeostasis of intracellular pH (pHi ) plays vital roles in many cell functions, such as proliferation, apoptosis, differentiation and metastasis. Thus far, Na+ -H+ exchanger (NHE), Na+ -HCO3 - co-transporter (NBC), Cl- /HCO3 - exchanger (AE) and Cl- /OH- exchanger (CHE) have been identified to co-regulate pHi homeostasis. However, functional and biological pHi -regulators in human dental pulp stem cells (hDPSCs) have yet to be identified. DESIGN: Microspectrofluorimetry technique with pH-sensitive fluorescent dye, BCECF, was used to detect pHi changes...

Dentists must be skilled when using dental mirrors. Working with mirrors requires spatial perception, bimanual coordination, perceptual learning and fine motor skills. Many studies have attempted to determine the predictors of manual skills among pre-clinical students, but consensus has yet to be reached. We hypothesized that valid and reliable occupational therapy test performance regarding indirect vision would differ between dental students and junior dentists and would explain the variance in manual skill performance in pre-clinical courses...

Traditionally, periodontal hand instruments are honed or sharpened during patient care as they dull easily during contact with enamel, calculus and cementum. This approach is taught in dental and hygiene schools around the world and remains the standard of care. Recently, some professional organizations have questioned whether this practice should be abandoned because of safety issues. Questions have been raised whether sharpening stones can be properly sterilized and whether the sharpening of contaminated instruments poses a health hazard for the provider...
