Background : Treatment of furcation‐involved molars presents a clinical challenge. This study retrospectively investigates the demographic parameters affecting treatment decisions and outcomes of root‐resected molars using a nationwide population‐based dataset. Methods: De‐identified data from 471 eligible patients were obtained from a representative cohort composed of 1 million of Taiwan's population. Demographic factors that influence treatment decisions and outcomes of root‐resected teeth were examined. Cox regression was performed to statistically analyze the factors. Results: The overall survival rate for root‐resected molars was 91.1%. The survival times of the extracted and surviving teeth were 303.0 ± 274.6 and 551.8 ± 327.2 days, respectively ( P <0.001). The analyzed patient‐related factors, such as living district, urbanization level, medical institution, and monthly income, have remarkable influence on treatment decisions; however, there is no statistically significant difference in survival rate between root‐resected molars receiving flap surgery and those that do not ( P = 0.504). After adjusting for other factors, patients aged >74 years have 3.33 times (hazard ratio = 3.33; 95% CI = 1.04 to 10.66; P = 0.043) higher rates of molar extraction than younger counterparts. Conclusions: The overall survival rate of root‐resected molars was satisfactory. Patients with advanced age (>74 years) had a higher risk of extraction occurrence on resected molars. Patient‐related factors may influence the treatment decision of whether molars receive flap surgery. These findings suggest that demographic factors should be carefully evaluated before and after performing root‐resection procedures because these factors may eventually impact the outcome of root‐resected molars.
