【摘要】:目的本研究通过测量牙列缺损患者可摘局部义齿修复前后的咀嚼功能和吞咽阈值,探讨后牙咬合对数(Posterior Occluding Pairs, POPs)与口腔咀嚼功能的相关性。 方法根据牙齿数目和后牙咬合对数将患者分为四组,A组对照组和B,C,D实验组。A组:上下颌至少28颗牙齿,至少8个POPs;B组:单颌至少10颗牙齿,至少5个POPS;C组:单颌至少10颗牙齿,含3-4个POPs;D组:单颌少于10颗牙齿,含1-2个POPs。分别在修复治疗前和治疗后一周,进行口腔检查,通过问卷调查测量患者对8种食物的主观咀嚼功能;通过咀嚼人工测试食物测量客观咀嚼功能,同时记录患者达到吞咽阈值时的咀嚼次数和咀嚼时间。 结果 1.修复治疗前,A组达到吞咽阈值时的咀嚼次数为37.73±15.23,B组39.30±12.77,D组81.40±32.83,均大于A,B组(P0.05)。修复治疗后,吞咽阈值的咀嚼次数B组53.6±38.79,C组67.71±19.40,D组80.27±21.80,A组少于C,D组,B组少于D组(P0.05)。修复治疗后B,C,D各组咀嚼次数无显著性修复(P0.05)。 2.修复治疗前,患者达到吞咽阈值时的咀嚼时间A组29.59±13.86,B组30.60±9.91,D组53.00±18.88,A,B组均少于D组。修复治疗后,吞咽阈值的咀嚼时间C组48.86±11.89,D组52.40±11.96,A组少于C,D组(P0.05)。B,C,D组在治疗后达到吞咽阂值的咀嚼时间较治疗前未减少(P0.05)。 3.修复治疗前,A, B, C, D组X50分别为3.31±0.81,4.77±0.97,5.114±0.50,5.44±0.28,对照组客观咀嚼效率高于实验组,B组高于D组(P0.05);修复治疗后,A, B, C, D组X50分别为3.31±0.81,4.19±1.01,4.57±0.35,4.88±0.42,对照组客观咀嚼效率仍然高于各实验组,B组高于D组。B,C,D三组客观咀嚼效率与治疗前比较均有提高(P0.05)。 4.在修复治疗后,B组咀嚼软性食物能力提高(治疗前1.51±0.61,治疗后1.20±0.37);C组咀嚼硬性食物和软性食物的能力均未有显著提高(P0.05),D组硬性食物(治疗前2.61±1.46,治疗后2.13±1.12)和咀嚼软性食物(治疗前1.88±0.96,治疗后1.52±0.64)的能力均有显著提高。 5.随着义齿修复的牙齿数目增加,患者达到吞咽阂值时的咀嚼次数和咀嚼时间,客观咀嚼效率,平均咀嚼食物能力,咀嚼硬性食物能力和软性食物能力的变化无统计学差异。 6.随着义齿修复的POPs数目增加,患者客观咀嚼效率,平均咀嚼食物能力和咀嚼软性食物能力显著提高。 结论牙列中,后牙咬合对数与客观咀嚼功能呈正相关,后牙咬合对数越多,客观咀嚼效率越高,吞咽阈值所用咀嚼次数和咀嚼时间越少;后牙咬合对数与主观咀嚼功能有一定程度的相关性;可摘局部义齿可提高牙列缺损患者的客观及主观咀嚼功能。咀嚼功能的改善程度与义齿增加的后牙咬合对数密切相关。
[Abstract]:Objective to investigate the correlation between the logarithmic (Posterior Occluding Pairs, POPs) of posterior teeth occlusion and oral masticatory function by measuring the masticatory function and swallowing threshold of removable partial denture in patients with dentition defect. Methods according to the number of teeth and the number of occlusal teeth, the patients were divided into four groups: group A (control group) and group A (group D). Group A: at least 28 upper and mandibular teeth, and at least 8 POPs;B groups: at least 10 teeth with a single jaw and at least 5 POPS;. Group C: at least 10 teeth with a single jaw, including 3-4 POPs;D groups: less than 10 teeth in a single jaw, including 1-2 POPs. Oral cavity examination was performed before and one week after treatment, and subjective masticatory function of 8 kinds of food was measured by questionnaire. The objective masticatory function was measured by artificial chewing test. The mastication times and the masticatory time were recorded when the patients reached the swallowing threshold. Result 1. Before repair treatment, the masticatory times of group A reached the threshold of swallowing was 37.73 卤15.23, group B was 39.30 卤12.77, group D was 81.40 卤32.83, which was higher than that of group A (P0.05). After repair treatment, the mastication times of group B (53.6 卤38.79) and group B (67.71 卤19.40) were less than those of group C (80.27 卤21.80) and group B (P 0.05). The mastication times of BCU D group were not significantly repaired after repair (P0.05). 2. Before repair, the masticatory time of group A (29.59 卤13.86) and group B (30.60 卤9.91) were less than that of group D (53.00 卤18.88). After repair treatment, the masticatory time of swallowing threshold in group C (48.86 卤11.89) was less than that in group C (52.40 卤11.96) (P0.05). The mastication time of group D to reach swallowing threshold after treatment was not decreased compared with that before treatment (P0.05). 3. The X50 of, A, B, C, D group was 3.31 卤0.81 卤0.97 卤0.97 卤0.97 卤0.57 卤0.50 卤5.44 卤0.28, respectively. The objective masticatory efficiency of the control group was higher than that of the experimental group, and that of the B group was higher than that of the D group (P0.05). After repair treatment, the X50 of, A, B, C, D group was 3.31 卤0.81U 4.19 卤1.01U 4.57 卤0.35 卤4.88 卤0.42.The objective masticatory efficiency of the control group was still higher than that of the experimental group, and that of the B group was higher than that of the D group, and the masticatory efficiency of the control group was higher than that of the D group. The objective masticatory efficiency in group D was higher than that before treatment (P0.05). 4. In group B, the ability of chewing soft food was improved (1.51 卤0.61 before treatment and 1.20 卤0.37 after treatment). In group C, the ability of chewing hard food and soft food was not significantly improved (P0.05) in group), D (2.61 卤1.46 before treatment, 2.13 卤1.12 after treatment) and soft food (1.88 卤0.96 before treatment). The ability of 1.52 卤0.64) was significantly improved after treatment. 5. With the increase of the number of teeth restored by denture, there was no significant difference in the number of mastications and the masticatory time, the objective masticatory efficiency, the average chewing ability, the masticatory ability of hard food and the ability of soft food when the patients reached the threshold of swallowing. 6. With the increase of the number of POPs in denture restoration, the objective masticatory efficiency, the average chewing ability and the masticatory soft food ability of the patients were significantly improved. Conclusion in dentition, the logarithmic occlusal of posterior teeth is positively correlated with the objective masticatory function. The more logarithmic occlusal pairs of posterior teeth are, the higher the objective masticatory efficiency is, and the less masticatory times and masticatory time are used for swallowing threshold. The logarithmic occlusal of posterior teeth was correlated with subjective masticatory function to some extent, and removable partial denture could improve the objective and subjective masticatory function of patients with dentition defect. The improvement of masticatory function is closely related to the logarithmic occlusal of posterior teeth.
