This study explored the clinical effect of root canal obturation by vertical condensation in elderly patients with chronic pulpitis. One hundred elderly patients with chronic pulpitis who were treated in our hospital from October 2021 to July 2022 were retrospectively selected as the study subjects, and according to the different treatment methods, they were divided into a study group (n=50, underwent vertical condensation for root canal obturation) and a control group (n=50, underwent cold lateral condensation for root canal obturation). The clinical therapeutic effect of the two groups was compared. The study group had 20 significant effective cases and 29 effective cases, with an overall effective rate of 98.00% (49/50), which was significantly higher than 86.00% (43/50) of the control group (P<0.05). At 3 months and 1 year postoperatively, the study group exhibited significantly lower GI values and periapical radiolucency areas compared to the control group, while demonstrating higher periapical bone density and masticatory function scores (P<0.05). At the 1-year follow-up, the study group showed significantly higher root canal filling densities in the coronal, middle, and apical thirds, as well as the average density, compared to the control group (P<0.05). Postoperative complications in the study group included one case of pain and one case of swelling, with an overall complication rate of 6.00% (3/50), which was not statistically different from the control group’s complication rate of 8.00% (4/50) (P>0.05). Additionally, the study group had significantly higher quality of life scores at 3 months and 1 year postoperatively compared to the control group (P<0.05). Root canal obturation by vertical condensation had a significant therapeutic effect in elderly patients with chronic pulpitis, which was conducive to improving the masticatory function of patients, exhibiting favorable long-term follow-up outcomes, improved quality of life, and a commendable safety.
