Statement of problem

Improvement in the masticatory function after replacing missing teeth is one of the main expected outcomes that need to be comprehensively measured with both clinical and patient-centered assessments. An evaluation of the responsiveness of these methods is lacking.

Purpose

The purpose of this clinical study was to assess the responsiveness of both objective and subjective methods for measuring the impact of different conventional prostheses on masticatory function at prosthesis delivery and 2 months later.

Material and methods

Participants (N=118) requiring prosthetic rehabilitation were selected from patients attending the Faculty of Dentistry of the University of Salamanca. Masticatory function was assessed by means of subjective methods (self-rated ordinal scales, visual analog scale, and food intake ability questionnaire) at baseline and 2 months after treatment. The ability to mix 2-colored chewing gum after 5, 10, and 15 cycles was also evaluated objectively. The responsiveness of each method was categorized by the effect size (ES) as low (<0.5), moderate (0.5 to 0.8), or large (>0.8).

Results

The study revealed that in all subgroups, the masticatory function improved 2 months after the treatment. The most responsive method was the visual analog scale (ES: 1.2) and the number of pattern foods perceived to be easily masticated by participants (ES: 0.7 to 1.3). By contrast, the masticatory performance assessed by using the mixing ability test showed a smaller magnitude of change (ES: 0.3 to 0.7). Both the objective and subjective masticatory functions were coherently correlated with age and clinical variables (number of occlusal units or the Eichner index) in all subgroups. However, masticatory performance and masticatory ability were not significantly correlated (r=0.22; P=.12).

Conclusions

Conventional prosthetic treatments significantly improve masticatory function 2 months after delivery, and the subjective methods were the most responsive in assessing changes in participants.

评估常规假体治疗后咀嚼功能的受试者短期内变化的不同方法的响应性。

问题陈述

替换缺失牙齿后咀嚼功能的改善是需要通过临床和以患者为中心的评估进行全面衡量的主要预期结果之一。缺乏对这些方法的响应性的评估。

目的

这项临床研究的目的是评估客观和主观方法对测量不同常规假体对分娩时及两个月后咀嚼功能的影响的反应性。

材料与方法

需要修复的参与者(N = 118)选自萨拉曼卡大学牙科学院的患者。在治疗初期和治疗后2个月,通过主观方法(自评序数表,视觉模拟量表和食物摄入能力问卷)对咀嚼功能进行评估。还客观评估了5、10和15个循环后混合2色口香糖的能力。每种方法的响应度按效果大小(ES)分为低(<0.5),中(0.5-0.8)或大(> 0.8)。

结果

研究显示,在所有亚组中,治疗后2个月咀嚼功能均得到改善。响应最快的方法是视觉模拟量表(ES:1.2)和参与者容易咀嚼的图案食物的数量(ES:0.7至1.3)。相比之下,通过混合能力测试评估的咀嚼性能显示出较小的变化幅度(ES:0.3至0.7)。在所有亚组中,客观和主观咀嚼功能均与年龄和临床变量(咬合单位数或艾希纳指数)密切相关。但是,咀嚼性能和咀嚼能力没有显着相关性(r = 0.22;P = 0.12)。

结论

分娩后两个月,传统的假肢治疗可显着改善咀嚼功能,而主观方法对评估参与者的变化反应最为迅速。
