Fracture and retention loss hazard ratio (95%CI) for pairwise comparison of different groups
carious lesion
CAVITY
Regarding the type of cavity (class I and II), the loss of restorations was distributed according to the following: for SEEBSy (class I: 50%, class II: 50%), for SETBSy (class I: 45%, class II: 55%), for SETBCa (class I: 43%, class II: 57%), for SEEIn (class I: 50%, class II: 50%), and for SETIn (class I: 47%, class II: 53%). Regarding the treatment reason (carious lesion and restoration replacement), the loss of restorations was distributed as follows: for SEEBSy (carious lesion: 34%, restoration replacement: 66%), for SETBSy (carious lesion: 55%, restoration replacement: 45%), for SETBCa (carious lesion: 57%, restoration replacement: 43%), for SEEIn (carious lesion: 42%, restoration replacement: 58%), and for SETIn (carious lesion: 53%, restoration replacement: 47%). Although no statistical analysis was conducted, mainly due to the low number of lost restorations, the descriptive statistics suggested that a similar percentage of restoration was lost, regardless of the type of cavity and treatment reason.
