          A new scoring system, the Basic Erosive Wear Examination (BEWE), has been designed to provide a simple tool for use in general practice and to allow comparison to other more discriminative indices. The most severely affected surface in each sextant is recorded with a four level score and the cumulative score classified and matched to risk levels which guide the management of the condition. The BEWE allows re-analysis and integration of results from existing studies and, in time, should initiate a consensus within the scientific community and so avoid continued proliferation of indices. Finally, this process should lead to the development of an internationally accepted, standardised and validated index. The BEWE further aims to increase the awareness of tooth erosion amongst clinicians and general dental practitioners and to provide a guide as to its management.

            Dental erosion -- changing prevalence? A review of British National childrens' surveys.

            To investigate the change in the prevalence of dental erosion, over time, by a review of the data from the published national dental surveys of young people in the UK. A subsidiary objective was to investigate the relationship between erosion and possible associated risk factors. The review was based on cross-sectional prevalence studies incorporating a clinical dental examination and structured interviews. The data were collated from the 1993 UK childrens' dental health survey and the dental report of the two National Diet and Nutrition Surveys (NDNS) of children aged 1(1/2)-4(1/2) in 1992/3 and 4-18 years in 1996/7. The criteria used for data collection were comparable between the three different studies. Comparing the data from the different studies, the prevalence of erosion was seen to increase from the time of the childrens' dental health survey in 1993 and the NDNS study of 4-18-year-olds in 1996/7. There was a trend towards a higher prevalence of erosion in children aged between 3(1/2) and 4(1/2) and in those who consumed carbonated drinks on most days compared with toddlers consuming these drinks less often. Drinks overnight were associated with an increased prevalence of erosion. More 4-6-year-olds with reported symptoms of gastro-oesophageal reflux had erosion compared with symptom-free children. On multivariate analysis, the strongest independent association with erosion was geography, with children living in the North having twice the odds of having erosion compared with those in London and the South-east. Comparing prevalence data from cross-sectional national studies indicates that dental erosion increases between different age cohorts of young people over time. Dietary associations with erosion are present but weak. Similarly, there is an association apparent between erosion, symptoms of gastro-oesophageal reflux and socio-demographic variables such as region of domicile, social class, and receipt of social benefits.

              Periodontal Screening and Recording (PSR) Index: precursors, utility and limitations in a clinical setting.

              Periodontal disease is a widespread condition ranging from simple gingival inflammation to severe periodontal breakdown. Early detection and diagnosis are key elements in the prevention of this oral pathology. Diagnostic aids available to dentists, such as the Periodontal Screening and Recording or PSR Index, accelerate the screening of periodontal conditions. While many studies provide support for the PSR Index as a valuable tool because it is reproducible, reliable, and quick, others have suggested that it may under or overestimate existing periodontal conditions. Some authors have suggested modifications to the recording method to improve its use either for screening purposes or for monitoring the outcome of periodontal therapy. This literature review briefly describes the PSR method, and compares studies based on both PSR and its counterpart, CPITN, in order to evaluate its usefulness and establish its limitations in a clinical setting.
