“…This rate of agreement is comparable with the intraobserver rate found in this study (86.4%) and rates noted by Murray et al (1984) liability. Furthermore, this standard may be used by someone trained in dentistry, but with only limited (less than 2 weeks) training in the evaluation of dental defects.…”

“…Interobserver agreement on the presence or absence of an enamel hypoplasia was reached on 80.8% of 177 teeth (Table 1). This rate of agreement is comparable with the intraobserver rate found in this study (86.4%) and rates noted by Murray et al (1984) and Suckling and Pearce (1984) for all enamel defects. These results suggest that the publication of the FDI standard has increased re- liability.…”

“…i' values are uncorrected; P values are two-tailed moderate malnutrition, 3) individual's ages at time of development of defects were assessed in a field situation, and 4) a training session has been adopted to improve intraobserver and interobserver reliability. The FDI typology of defects showed relatively high intraobserver agreement in two other studies, both involving children studied in schools with the aid of a dental chair and artificial lights (Murray et al, 1984; Suckling and Pearce, 1984). Our intra-and interobserver agreement scores for identification of hypoplastic defects suggest that these defects may be scored under most field conditions with only minimal dental equipment (probes, mirrors), a chair, and natural lighting.…”

“…Two epidemiological studies of dental defects using FDI coding have included intraobserver reliability estimates. Murray et al (1984) noted an 82% agreement in the recording of opacities, and Suckling and Pearce (1984) and noted a 95% agreement on the presence of a defect of any type.…”

Enamel hypoplasias, deficiencies in enamel thickness resulting from disturbances during the secretory phase of enamel development, are generally believed to result from nonspecific metabolic and nutritional disruptions. However, data are scare on the prevalence and chronological distributions. of hypoplasias in populations experiencing mild to moderate malnutrition. The purpose of this article is to present baseline data on the prevalences and chronological distributions of enamel hypoplasias, by sex and for all deciduous and permanent anterior teeth, in 300 5 to 15-year-old rural Mexican children. Identification of hypoplasias was aided by comparison to a published standard (Federation Dentaire Internationale: Int. Dent. J. 32(2):159-167, 1982). The location of defects, by transverse sixths of tooth crowns, was used to construct distributions of defects by age at development. One or more hypoplasias were detected in 46.7% (95% CI = 40.9-52.5%) of children. Among the unworn and completely erupted teeth, the highest prevalence of defects was found on the permanent maxillary central incisors (44.4% with one or more hypoplasias), followed by the permanent maxillary canine (28.0%) and the remaining permanent teeth (26.2 to 22.2%) Only 6.1% of the completely erupted and unworn deciduous teeth were hypoplastic. The prevalence of enamel defects on the permanent teeth was up to tenfold greater than that found in studies of less marginal populations that used the FDI method. The prevalence of defects in transverse zones suggests a peak frequency of hypoplasias during the second and third years for the permanent teeth, corresponding to the age at weaning in this group. In the deciduous teeth, a smaller peak occurs between 30 and 40 weeks post gestation. The frequency of defects after three years of age is slightly higher in females than males, suggesting a sex difference in access to critical resources.

“…Other studies have reported that diffuse opacities (DDE index) have been the opacity type to distinguish the difference in prevalence between high and low fluoridated areas (11, 12, 24‐27). In the current study the highest level of diffuse opacities was found in Cork, as one would expect because this is the only city with a fluoridated water supply.…”

There is very little contemporary evidence, meeting the review's inclusion criteria, that has evaluated the effectiveness of water fluoridation for the prevention of caries.The available data come predominantly from studies conducted prior to 1975, and indicate that water fluoridation is effective at reducing caries levels in both deciduous and permanent dentition in children. Our confidence in the size of the effect estimates is limited by the observational nature of the study designs, the high risk of bias within the studies and, importantly, the applicability of the evidence to current lifestyles. The decision to implement a water fluoridation programme relies upon an understanding of the population's oral health behaviour (e.g. use of fluoride toothpaste), the availability and uptake of other caries prevention strategies, their diet and consumption of tap water and the movement/migration of the population. There is insufficient evidence to determine whether water fluoridation results in a change in disparities in caries levels across SES. We did not identify any evidence, meeting the review's inclusion criteria, to determine the effectiveness of water fluoridation for preventing caries in adults.There is insufficient information to determine the effect on caries levels of stopping water fluoridation programmes.There is a significant association between dental fluorosis (of aesthetic concern or all levels of dental fluorosis) and fluoride level. The evidence is limited due to high risk of bias within the studies and substantial between-study variation.
