AIM To compare part-time and full-time Essix-type retainer wear regimens following fixed appliance treatment, with respect to dental alignment and occlusal changes. METHODS In this prospective study, 60 patients were randomly allocated to either full-time or part-time Essix retainer wear following fixed appliance therapy. Study casts were taken before(More)
UNLABELLED 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(More)
It is essential that every health care professional who is involved with the prescription or recommendation of drugs be fully aware of any resultant disorders that may arise as a side-effect. A range of drugs can affect the teeth. In this review article, drugs that have the potential to induce changes in teeth have been classified as those leading to tooth(More)
The aim of this article is to outline some of the factors practitioners should take into consideration when planning optimal smile aesthetics. The components of the smile that will be discussed include the smile are, incisor/gingival display, smile width, gingival aesthetics, tooth proportionality/symmetry, contacts/connectors/embrasures and the dental(More)
PURPOSE The labial margins of anterior implant-retained crowns are often positioned subgingivally for a superior esthetic appearance. One of the consequences of subgingival margins is the increased risk of leaving excess cement behind following cementation. This can lead to potential problems, including peri-implant inflammation, soft tissue swelling,(More)
This in vitro study evaluated gingival wall microleakage in packable and microhybrid conventional composite restorations with and without a flowable composite liner. Each group was evaluated with gingival margins situated in both enamel and cementum/dentin. Two hundred and forty Class II cavities were prepared in extracted third molars, half with gingival(More)
OBJECTIVES To investigate the degree of association between tactile and optical criteria as used to assess the carious status of the enamel-dentine junction (EDJ) during cavity preparation, assessment with a caries detector dye and detection of Streptococcus mutans using culture and polymerase chain reaction (PCR) techniques. METHODS Twenty-nine teeth,(More)
OBJECTIVE The objective of this study was to undertake a clinical evaluation of the individual repeatability of three colour measuring devices. DESIGN Clinical study. Setting Eastman Dental Hospital. METHODS Under standardised clinical conditions, one trained operator using three colour measuring devices (Vita Easyshade, X-Rite ShadeVision and(More)
PURPOSE Factors affecting the retention of fixed prostheses to natural abutments are well understood. In contrast, little is known concerning factors influencing the retention of fixed prostheses cemented to implant abutments. The purpose of this study was to investigate the effect that varying implant abutment wall height, platform size, and screw access(More)
