Analysis on clinical curative effects of molar teeth in elderly people after variation root canal treatment

Objective:To study the curative effects of molar teeth in elderly people after using variation root canal treatment. Method:85 teeth from 83 elderly and 82 teeth from 79 young patients were reexamined, which had received root canal treatment, variation root canal treatment(rough canal: root canal treatment, fine canal: resinifying therapy) or resinifying therapy 2 years ago. The curative effects were evaluated based on clinical examination and radiographic assessment using periapical index(PAI). Result:There are no statistically significant difference for the overall healing rates between the first two groups (P0.05). Statistically significant difference were found for the overall healing rates between the first group and the last group (P0.05). Conclusion:The long-term curative effects of variation root canal treatment to teeth with chronic apical periodontitis in elderly people were decided. Using different treatment according to root morphology in elderly molar teeth was reasonable.
