Resultswith local changes at the time of tooth development, for example trauma or infection in theprimary dentition. The prevalence of these opacities was similar among all groups. Theprevalence of hypoplasia and combinations of opacities was low in all groups. Furtherexploration of these data will be presented in the final report.Table 7Percentage of children and adolescents in RoI and NI with opacities recorded on theirteeth according to age group, fluoridation status and type of opacity◆ ● ▲ statistically significant (p< 0.05) difference between pairs of groups marked with samesymbolsAge 8Fluoridated RoI Non Fluoridated RoI Non Fluoridated NIAny Opacity 52◆ 35◆▲ 51▲Demarcated 15 15 17Diffuse 41◆ 22◆▲ 41▲Hypoplastic 1◆● 2◆ 4●Demarcated and Diffuse 4◆ 1◆▲ 4 ▲Demarcated and Hypoplastic 0 0 1Diffuse and Hypoplastic 1● 0 ▲ 2●▲All three 0 0 0Age 12Fluoridated RoI Non Fluoridated RoI Non Fluoridated NIAny Opacity 58◆● 42◆ 47●Demarcated 17 19 20Diffuse 49◆● 29◆ 34●Hypoplastic 3 2 4Demarcated and Diffuse 5◆ 2◆ 4Demarcated and Hypoplastic 0 0 1Diffuse and Hypoplastic 1 1 2All three 0 0 0Age 15Fluoridated RoI Non Fluoridated RoI Non Fluoridated NIAny Opacity 62◆● 50◆ 52●Demarcated 18 19 22Diffuse 52◆● 37◆ 40●Hypoplastic 2◆● 2◆ 6●Demarcated and Diffuse 5◆ 3◆▲ 6 ▲Demarcated and Hypoplastic 0◆ 1◆ 1Diffuse and Hypoplastic 3◆ 2◆ 2All three 0● 0▲ 1●▲Trauma to Front TeethDuring the dental examination, the examiners assessed each permanent incisor in the 8-, 12-and 15-year-old children for evidence of damage.
