Aim: The aim of this study is to compare postoperative pain of RetroMTA and resin-based tricalcium silicate (TheraCal LC) versus chemically Cured Glass Ionomer base material (FujiXI) in conservative management of very deep carious lesions by selective caries removal clinically and by digital radiography over 24 months.
Materials and methods: 99 teeth of patients were selected to participate in the study. All the selected teeth were divided in three groups (Fuji IX), (MTA) and (Theracal) groups. Teeth with deep caries undergone selective caries removal and the tested lining materials were placed in the base of the cavity then composite were placed over as a final restoration. Postoperative pain (using thermal, percussion and palpation tests) and periapical pathosis (using digital periapical radiograph) were tested initially at (T0), after one week (T1), after three months (T3), after six months (T6), after 12 months (T12) and after 24 months (T24). After follow up period only 90 teeth were statistically analyzed using R statistical analysis software version 4.3.1 for Windows1.
Result: the success rate after overall assessment (clinical and radiographic) of the three lining materials Fuji XI, RetroMTA, Theracal LC, was: 53.3, 73.3, and 60 % respectively. The differences between groups were not statistically significant (p>0.05).
Conclusions: the three lining material (Fuji XI, RetroMTA, TheraCal LC ) have almost the same clinical and radiographic success rate after 2 years follow up period. Both RetroMTA and Theracal LC have favorable and comparable success rates when used in partial caries lining in very deep carious lesions.
