A 36-item questionnaire was used to investigate the stress perceived by students
at Manchester Dental School to potential stressors, grouped under the headings
of living accommodation, personal factors, educational environment, academic
work and clinical factors. The stressors producing the highest ratings for
perceived stress varied throughout the course but high values were allocated to

This article discusses the effects of sex steroid hormones, glucocorticoids and
insulin deficiency on periodontal tissues, and the possible consequences on
periodontal disease progression. The androgens and oestrogens have predominantly
anabolic functions in stimulating matrix synthesis, which is applicable to
periodontal repair and medication-induced gingival overgrowth. Oestrogen and
progesteron... hiện toàn bộ
Light activation units are standard items of equipment in dental practice. It is
essential to understand the many factors which affect the polymerization of
light-activated resin composite materials and the choice of a light curing unit.
In this respect, the development of high-intensity halogen and light-emitting
diode (LED) light curing units (LCUs), many with multiple curing modes, has
revoluti... hiện toàn bộ
The implant-retained overdenture has been advocated as an effective method of
restoring the edentulous patient with an appliance that offers significant
benefits over conventional prosthetics. However, the success and survival of
such appliances have been shown to vary considerably, depending on which jaw is
treated: implants supporting overdentures in the maxilla have a significantly
higher failu... hiện toàn bộ
The assessment and operative long-term management of direct restorations is a
complex and controversial subject in conservative dentistry. Employing a
minimally invasive (MI) approach helps preserve natural tooth structure and
maintain endodontic health for as long as possible during the restorative cycle.
This paper discusses how minimally invasive techniques may be applied
practically to reviewi... hiện toàn bộ
Magnets are a popular method of attaching removable prostheses to either
retained roots or osseointegrated implants. This paper reviews the development
of magnets in dentistry and describes the different types of magnetic
attachments that are available. The clinical applications of magnets in
prosthetic dentistry are illustrated and future technological advancements
indicated. Whilst different mag... hiện toàn bộ
Fear and anxiety are common responses to anticipated or actual dental treatment.
This may range from slight feelings of unease during routine procedures, such as
an injection or cavity preparation, to feelings of extreme anxiety long before
treatment is happening. There is general agreement that anxiety constitutes a
major problem for the dentist, and a barrier to optimal care for the patient, as

Taurodontism is the morpho-anatomical change in the shape of a tooth, which
involves enlargement of the body of the tooth and shortening of the roots. It
has been reported in permanent and deciduous teeth, in premolars and molars and
associated with certain syndromes, particularly in those involving an ectodermal
defect. It has clinical implications which are relevant to both the general

The search for a clinically viable all-ceramic bridge framework has been
monotonous. Until recently, few materials appear to have the necessary physical
and aesthetic properties. However, the development of yttrium tetragonal
zirconia polycrystals, and its adoption for use in dentistry by CAD CAM
technology, may hold promise as a crown and bridge framework, this being
considered suitable for singl... hiện toàn bộ
Impacted third molars are a common reason for referral to the hospital dental
service. Third molar impaction can be complicated by infection. We present two
cases of osteomyelitis of the mandible developing secondary to pericoronitis of
partially erupted lower third molars. One of the cases reported was recently
diagnosed and treated while the other was diagnosed and treated 20 years ago.
