Burke FM, Whelton H, Harding M, Crowley E, O’Mullane D, Cronin M, Kelleher V, Byrtek M. Fluoridation and tooth wear in Irish adults. Community Dent Oral Epidemiol 2010; 38: 415–421. © 2010 John Wiley & Sons A/S The aim of this study was to determine the prevalence of tooth wear in adults in Ireland and its relationship with water fluoridation. The National Survey of Adult Oral Health was conducted in 2000/2001. Tooth wear was determined using a partial mouth examination assessing the upper and lower anterior teeth. A total of 2456 subjects were examined. In this survey, increasing levels and severity of tooth wear were associated with ageing. Men were more affected by tooth wear and were more likely to be affected by severe tooth wear than women. It was found that age, and gender were significant predictors of tooth wear ( P < 0.01). Overall, there was no significant relationship between fluoridation and tooth wear in this study. [ABSTRACT FROM AUTHOR]

A conference paper about the impact of changing global patterns of dental caries experience on clinical trials in dental caries is presented. It discusses changes in dental caries levels from the 1970s to 2001 with a focus on 12-year-olds from 8 demographic regions. It examines the effects of these changes on clinical trials in children, adults, rate of progression, and fissure sealant.

The aims of this study were to estimate the average maximum mouth opening and range of mouth opening in a representative sample of the Irish adult population, to compare mouth opening in patients with and without signs or symptoms of temporomandibular joint (TMJ) dysfunction syndrome and to investigate the association between mouth opening and stature among populations. As part of the Irish National Survey of Adult Oral Health, maximum mouth opening was measured and questionnaire data collected for 1513 adults, aged 16–99 years. The average maximum mouth opening was 43 mm for males and 41 mm for females. Mouth opening was found to reduce with age, independent of gender. No link was found between reduced mouth opening and TMJ dysfunction or between mouth opening and stature in populations. [ABSTRACT FROM AUTHOR]
