The restorations replaced for another treatment (n = 28) and the teeth extracted (n = 5) were excluded (scored as Oscar). The percentages given for caries and marginal adaptation relate to all restorations evaluated (n = 96). For other USPHS categories, percentages relate to restorations present without fractures (n = 81)
