Abstract

Purpose: This study aimed to evaluate masticatory performance in cases where one molar was missing.

Methods: Participants were 156 adults with one molar missing from their natural teeth, who were divided into group A (without prosthetic treatment) and group B (with prosthetic treatment). The non-missing side was designated as A1 or B1, and the missing side was designated as A2 or B2. The amount of glucose eluted (AG) when the participants chewed a gummy jelly was measured and used as a parameter for masticatory performance. AG was compared between the non-missing side (A1, B1) and missing side (A2, B2), and between the first molar missing group and second molar missing group.

Results: AG was significantly greater on the dentate side (P < 0.001) and was significantly less in the A2 group when the first molar was missing (P = 0.002). The rate of decrease of AG was 11.1%, 14.3%, and 8.4% in groups A+B, A, and B, respectively.

Conclusion: Masticatory performance appears to decrease even with only one missing molar. Although improvement is achieved by prosthetic treatment, performance remains inferior to that on the dentate side.

缺失一颗臼齿的咀嚼性能。

目的：本研究旨在评估缺失一颗臼齿的情况下的咀嚼性能。方法：参与者是156名自然牙齿缺失一颗臼齿的成年人，他们被分为A组（未接受假牙治疗）和B组（接受假牙处理）。未缺失的一侧被指定为A1或B1，而缺失的一侧则被指定为A2或B2。当参与者咀嚼果冻时，葡萄糖洗脱量（AG）被测量并用作咀嚼性能的参数。比较未缺失侧（A1，B1）和缺失侧（A2，B2）之间以及第一磨牙缺失组和第二磨牙缺失组之间的AG。结果：牙齿侧AG显著增加（P＜0.001），A2组在第一磨牙缺失时AG显著减少（P＝0.002）。A+B组、A组和B组的AG减少率分别为11.1%、14.3%和8.4%。结论：即使只有一颗缺失的臼齿，咀嚼性能也会下降。尽管通过假体治疗可以获得改善，但其性能仍不如齿状侧。
