Introduction: A systematic review and meta-analysis were conducted to evaluate the physicomechanical properties of tertiary monoblock obturation with different obturation techniques. Methods and Materials: PubMed (MEDLINE), Web of Science, Scopus, the Cochrane Library, LILACS, IBECS, and BBO were searched time. PICO question was: "In extracted human teeth (Population), does tertiary monoblock obturation (Intervention) have superior physicomechanical properties (Outcome) compared to conventional obturation systems (Comparison)?". Statistical analyses for push-out bond strength were performed with RevMan software by comparing the mean differences of each study, with a 95% confidence interval. Inverse variance was used as statistical method, random-effects models as analysis model, and heterogeneity between studies was assessed by Cochran's Q test and I² statistic (P<0.05). Results: Of 2162 studies retrieved, 31 were included in this review for "Study Characteristics". Ten studies were included in the meta-analysis. Analysis demonstrated that conventional obturation had significantly higher push-out bond strength than tertiary monoblock obturation (P<0.01), with a mean difference of-1.00 (95% CI, -1.41 to -0.58; I²=100%). Subgroups using single-cone and cold lateral condensation techniques showed significantly lower push-out bond strength for tertiary monoblock obturation (P<0.01), respectively with a mean difference of-0.09 (95% CI, -1.13 to -0.67; I²=97%) and of-1.97 (95% CI, -3.19 to -0.75; I²=100%). The warm vertical compaction subgroup showed no statistically significant difference between tertiary monoblock and conventional systems (P=0.13), with a mean difference of 0.49 (95% CI, -0.14 to 1.12; I²=10%). Conclusion: Tertiary monoblock systems have a push-out bond strength similar'to conventional [ABSTRACT FROM AUTHOR] |
