OBJECTIVE In addition to its role as a remineralizing agent in preventing dental caries, calcium product (CPP-ACP) delivered as a mousse (Tooth Mousse, TM) can reduce erosion of enamel and dentine. The aim of this study was to determine whether CPP-ACP could also reduce erosive tooth wear involving toothbrush abrasion. METHODS Flat, polished enamel and(More)
OBJECTIVES To investigate the effect of an aqueous sodium fluoride solution of increasing concentration on erosion and attrition of enamel and dentine in vitro. METHODS Enamel and dentine sections from caries-free human third molars were polished flat and taped (exposing a 3 mm x 3 mm area) before being randomly allocated to 1 of 5 groups per substrate(More)
PURPOSE The aim of this study was to investigate data on the prevalence of tooth wear in adults and assess possible correlations using a systematic review. MATERIALS AND METHODS A search of the literature, using PubMed and the Cochrane Library, from January 1980 to July 2007 was made using keywords "tooth + wear"; "dental + attrition + prevalence";(More)
STATEMENT OF PROBLEM Heat-polymerized polymethyl methacrylate denture bases deform during and after polymerization, and this deformation may affect the clinical performance of complete dentures. PURPOSE The purpose of this study was to investigate the processing deformation of 3 denture base materials on a standardized anatomic model by using a contact(More)
OBJECTIVES To assess the dimensional stability of 8 impression materials over 12 weeks relevant to in vitro tribology studies. METHODS Ten impressions from eight impression materials were taken of a metal block (ADA block) conforming to the American Dental Association specification for impression materials and of another metal block (custom block) which(More)
The purpose of this study was to measure deformation of mandibular complete denture permanent bases after secondary curing. A cast of a flat mandibular edentulous ridge was duplicated ten times. A wax base was laid on the original cast, two wax sprues were attached and an overcast was made. The overcast was used to produce wax bases similar in outline and(More)
The aim of this study was to measure the progression of tooth wear in a cohort of 63 patients, 43 males and 20 females with a mean age of 39.1 years. Recruitment followed referral from general practice to Guy's Hospital for advice/management of tooth wear. Addition silicone impressions were taken at 6-month intervals for a total of 12 months; impressions(More)
OBJECTIVE To analyze differences in the way dental materials digitize on a non-contacting laser profilometer (NCLP). METHODS Three Type IV dental stones and 15 impression materials were mixed according to the manufacturer's instructions and expressed against a glass block to record its surface characteristics. From each material an area of 6 x 40 mm was(More)
OBJECTIVES To test the accuracy of measurements of tooth wear using a non-contacting laser profilometer (NCLP) and surface matching software. METHODS The accuracy and repeatability of the NCLP and software in measuring length was assessed by repeatedly scanning a calibrated 25 mm engineering steel gage block. Volumetric measurements were assessed after(More)
Data on the prevalence of tooth wear among children and adolescents are inconsistent. Given the impact of extensive tooth wear for over a lifetime, evidence on the extent is required. The aim was to systematically review the literature on the prevalence of tooth wear in children and adolescents. A PubMed literature search (1980-2008) used the keywords(More)
