摘要

目的评价当代正畸治疗中常用的光固化正畸带水泥提咬对咀嚼功能的影响,并采用客观和主观两种方法进行评价。材料与方法对30例正常咬合的健康志愿者(女性19例,男性11例,年龄22.3±1.56岁)进行咀嚼功能客观评价和咀嚼能力主观评价。在咬举前后立即进行评估。在上颌第一磨牙腭尖添加光固化正畸带骨水泥(宽×长×高3 × 5 × 2 mm)进行升牙。用筛分法计算了咀嚼试验食品颗粒的咀嚼性能指数(MPI)。对于主观评价,参与者使用六种食物的问卷进行食物摄入能力(FIA)测试。确定评价方法之间的相关性。结果被试咬后MPI和FIA得分均显著降低(P < 0.001)。MPI和FIA分数的降低在男女之间无显著差异。在MPI和FIA评分的变化之间没有发现显著的相关性。结论光固化正畸带骨水泥提高咬合后,咀嚼功能在客观上和主观上均立即下降。然而,由于客观结果和主观结果之间没有显著的相关性,个体可能不会感觉到他/她的咀嚼能力下降的程度与咀嚼性能下降的程度相同。需要进一步的研究来评估对这种咬举方法的长期适应性。

Masticatory function after bite-raising with light-cured orthodontic band cement in healthy adults.
OBJECTIVES To evaluate the effects of bite-raising with light-cured orthodontic band cement, a method commonly used in contemporary orthodontic treatment, on masticatory function, as assessed by objective and subjective methods. MATERIALS AND METHODS The objective evaluation of masticatory performance and subjective evaluation of masticatory ability were performed on 30 healthy volunteers (19 females and 11 males, 22.3 ± 1.56 years) with a normal occlusion. Assessment was performed before and immediately after bite-raising. The bite-raising was done by adding light-cured orthodontic band cement (3 × 5 × 2-mm width × length × height) on the palatal cusps of the upper first molars. The masticatory performance index (MPI) was calculated from chewed test food particles using a sieving method. For the subjective evaluation, the participants performed the food intake ability (FIA) test using a questionnaire with six types of food. The correlation between the evaluation methods was determined. RESULTS The MPI and FIA scores of the participants were significantly reduced after bite-raising (P < .001). The MPI and FIA score reduction was not significantly different between females and males. No significant correlations were found between the changes in MPI and FIA scores. CONCLUSIONS Masticatory function after bite-raising with light-cured orthodontic band cement was immediately reduced, both objectively and subjectively. However, because there was no significant correlation between the objective and subjective results, an individual may not perceive his/her decreased masticatory ability to the same degree as masticatory performance was reduced. Further study is required to evaluate the long-term adaptation to this bite-raising method.
