A glass ionomer cement was applied as a fissure sealant to 115 maxillary and 117 mandibular permanent molars. The operators were student school dental therapists working in normal training conditions. Retention rates (93 per cent complete retention after 6 months, and 82.5 per cent complete retention after 12 months) were comparable with those obtained with Bis‐GMA resin sealants in other studies. Maxillary teeth accounted for 21 of the 35 teeth which lost sealant partly or completely. The linguo‐occlusal fissure of maxillary first permanent molars was the commonest site of sealant loss. Only 2 of the teeth which lost sealant were carious at the follow‐up assessments.
