UNLABELLED Hitherto, noncarious cervical lesions (NCCLs) of teeth have been generally ascribed to either toothbrush-dentifrice abrasion or acid "erosion." The last two decades have provided a plethora of new studies concerning such lesions. The most significant studies are reviewed and integrated into a practical approach to the understanding and designation of these lesions. A paradigm shift i...

OBJECTIVE To determine the occurrence and severity of dental erosion in alcoholic patients undergoing detoxification at the North Alcoholic Regional Centre (CRAN), Porto, Portugal, and to assess socioeconomic and behavioural covariates of dental erosion occurrence. DESIGN A cross-sectional descriptive study was carried out in one centre (CRAN) for addiction rehabilitation therapy in the north...

OBJECTIVE This study assessed the effect of fluoride varnishes on the progression of tooth erosion in vitro. MATERIAL AND METHODS Forty-eight enamel and 60 root dentin samples were previously demineralized (0.1% citric acid, pH 2.5, 30 min), leading to a baseline and erosive wear of 12.9 and 11.4 µm, respectively. The samples were randomly treated (6 h) with a 4% TiF4 varnish (2.45%F-, pH 1.0...

Subglacial erosion and sediment dynamics influence the size, stability, and climatic sensitivity of large ice sheets. These processes may regulate large-scale surging behavior, initiating rapid shifts in climate and sea level (MacAyeal, 1993a,b), and perhaps dictate the periodicity of the Quaternary ice ages (Clark and Pollard, 1998). We intuitivly associate the scoured landscapes of the northe...

Dental erosion, and specifically its symptoms, has long been studied in Japan as an occupational dental disease. However, in recent years, few studies have investigated the development of this disease or labor hygiene management aimed at its prevention. As a result, interest in dental erosion is comparatively low, even among dental professionals. Our investigation at a lead storage battery fact...

AIM The aim of the present in vitro study was the evaluation of two products: a CPP-ACP paste (GC Tooth Mousse, GC Corp.) and a desensitizing toothpaste (Colgate Sensitive Pro Relief, Colgate-Palmolive) on preventing enamel erosion produced by a soft drink (Coca Cola) by using Atomic Force Microscopy (AFM). METHODS Thirty enamel specimens were assigned to 6 groups of 5 specimens each. 1: inta...

Three trials, utilizing a total of 240 crossbred gilts, were conducted to study the influence of 0 (NB) or 220 (SB) microgram supplemental biotin/kg of diet on feedlot performance, plasma biotin and development of toe lesions in developing gilts. Corn-soybean meal diets were fed from weaning to 92 kg body weight. Gilts were housed on expanded-metal floors to 50 kg body weight and on partially s...

Background A sizable increase in the outbreak of tooth attrition and especially dental erosion has been observed. Detection of tooth wear, proper prevention, and effective intervention in the early stage will avoid the adverse effect on teeth performance and elegance. Thus, the current study aimed to determine the level of awareness of senior dental students (general dentists) about the preval...
