          Abstract

          Tooth wear—attrition, erosion and abrasion—is perceived internationally as an ever-increasing problem. Clinical and epidemiological studies, however, are difficult to interpret and compare due to differences in terminology and the large number of indices that have been developed for diagnosing, grading and monitoring dental hard tissue loss. These indices have been designed to identify increasing severity and are usually numerical. Some record lesions on an aetiological basis (e.g. erosion indices), others record lesions irrespective of aetiology (tooth wear indices); none have universal acceptance, complicating the evaluation of the true increase in prevalence reported. This article considers the ideal requirements for an erosion index. It reviews the literature to consider how current indices have evolved and discusses if these indices meet the clinical and research needs of the dental profession.

          Dental erosion in a population of Swiss adults.

          The purpose of this study was to determine the prevalence of dental erosion in an adult population in Switzerland. 391 randomly selected persons from two age groups (26-30 and 46-50 yr) were examined for frequency and severity of erosion on all tooth surfaces. Information was gathered by interview about lifestyle, dietary and oral health habits. For facial surfaces 7.7% of the younger age group and 13.2% of the older age group showed at least one tooth affected with erosion with involvement of dentin (grade 2). 3.5 teeth per person in the younger and 2.8 teeth per person in the older age group were affected. Occlusally, at least one severe erosion was observed in 29.9% of the younger and 42.6% of the older sample with 3.2 and 3.9 erosion-affected teeth per person, respectively. 3.6% of the younger age group and 6.1% of the older age group showed slight lingual erosion on the maxillary anterior teeth. Severe lingual erosions were scarce. Data from interviews and multiple regression analyses revealed that acids from beverages are significantly associated with presence of erosion.

            Dental erosion of nonindustrial origin. A clinical survey and classification.

            A survey was made from the clinical records of 72 patients diagnosed as suffering from dental erosion of nonindustrial origin. The information surveyed included dietary history, relevant medical history, clinical examination, and color photographs of the affected teeth. A new classification of erosion is proposed and the different types of lesions are described.

              Epidemiological studies of tooth wear and dental erosion in 14-year-old children in North West England. Part 1: The relationship with water fluoridation and social deprivation.

              The effect of water fluoridation upon dental erosion/tooth wear in the UK has not been investigated. This study aimed to compare the prevalence of tooth wear in 14-year-old schoolchildren in non-fluoridated and fluoridated districts of North West (NW) England. The influence of deprivation and tooth brushing was also investigated. A random sample of 10% of the 14-year-old population in NW England was selected and stratified according to fluoridation status as determined from water authority postcode listings. Tooth wear was scored on the labial, incisal and palatal/lingual surfaces of the 12 anterior teeth and the occlusal surfaces of the first molars. Enamel wear was scored 0, dentine was scored 1 or 2, dependent on whether less than or more than a third of the surface had exposed dentine. Secondary dentine or pulpal exposure scored 3. Townsend deprivation scores were gained from residential post codes. A total of 2,351 children were examined, of which 637 (27%) lived in the one fluoridated district of South Cheshire and 1,714 (73%) lived in 11 non-fluoridated districts. Fifty-three per cent of the children had exposed dentine with significantly more males affected than females (p<0.001). In the fluoridated district, significantly fewer children had exposed dentine on labial and palatal smooth surfaces (p<0.001) but no differences were found for incisal and occlusal surfaces. The interaction of fluoridation and tooth brushing twice per day resulted in a significant (30%) reduction in erosion. Smooth surface wear was more prevalent in children resident in affluent areas. Children in non-fluoridated districts are 1.5 times more likely to have smooth surface wear compared with children in fluoridated districts. Fluoridation and use of fluoridated toothpaste twice a day provide added protection from dental erosion. The risk of tooth wear is greater with increasing affluence.
