| Abstrakt: | 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 I 2 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; I 2 =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; I 2 =97%) and of -1.97 (95% CI, -3.19 to -0.75; I 2 =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; I 2 =10%). Conclusion: Tertiary monoblock systems have a push-out bond strength similar to conventional systems when used with warm vertical compaction. Competing Interests: ‘None declared’. |
