utcome of Root Canal Obturation by Warm Gutta-Percha ersus Cold Lateral Condensation: A Meta-analysis

C C bstract he purpose of this study was to evaluate clinical utcome differences of root canal obturation by warm utta-percha (GP) or cold lateral condensation (CLC) hrough a systematic review and meta-analysis. There ere 10 clinical studies evaluated. Postoperative pain, ong-term outcomes, obturation quality, and overextenion were the characteristics investigated. The results uggest that the two obturation techniques are not ignificantly different except in overextention. The reltive risk (RR) value of warm GP versus CLC and 95% onfidence interval (CI) of the first three criteria were .10 (0.71, 1.71), 0.78 (0.58, 1.05), and 1.31 (0.98, .76), respectively. Overextension was more likely to ccur in the warm GP obturation group in comparison ith the CLC group. The RR value and 95% CI were .98 (1.33, 2.93). In conclusion, warm GP obturation emonstrated a higher rate of overextension than CLC. ostoperative pain prevalence, long-term outcomes, nd obturation quality were similar between the two roups.
