【摘要】：目的应用全颌曲面断层片对异常吞咽患者前牙牙根吸收等级进行测量分析,探讨异常吞咽对牙根吸收的影响；通过对异常吞咽患者口呼吸的研究,探讨异常吞咽对口呼吸的影响,为错(?)畸形的早期矫治提供参考。方法研究一：选取2007-2012年间在北京新华医院口腔正畸科就诊的患者。通过临床检查筛选,根据样本纳入标准选择其中96人作为研究对象,异常吞咽组48人,正常吞咽组48人。年龄13-16岁,汉族。均为男16人,女32人。均采用北京通州新华医院放射科Planmeca Promax全景X射线系统拍摄,条件标准统一。应用姜若萍的改良牙根吸收分级法,在全颌曲面断层片上进行牙根吸收等级评判。将牙根吸收等级对应的牙数按牙根吸收与否进行合并,应用SPSS13.0进行卡方检验,比较异常吞咽组与正常吞咽组间有牙根吸收的牙数差异；应用秩和检验比较上下切牙、上颌中切牙与侧切牙及下颌中切牙及侧切牙牙根吸收的差异。研究二：选取2007-2012年期间在北京新华医院口腔正畸科就诊的患者。通过临床检查筛选,根据样本纳入标准选择其中76人作为研究对象,包括异常吞咽组38人,正常吞咽组38人(注：研究一与研究二样本不交叉)。年龄11-14岁,汉族。均为男7人,女31人。将存在口呼吸标为1,将不存在口呼吸标为0,应用SPSS13.0软件对两组数据进行卡方检验。结果 1.统计显示异常吞咽组与正常吞咽组间牙根吸收差异有统计学意义(P0.05)。 2.统计显示异常吞咽组与正常吞咽组口呼吸人数差异有统计学意义(P0.01)。结论 1.异常吞咽是牙根吸收的危险因素。 2.异常吞咽容易诱发口呼吸。 3.在错(?)畸形早期矫治中应关注异常吞咽的危害,训练患者正常吞咽,降低牙根吸收发生的机率。矫治异常吞咽也是主动矫治口呼吸的方法,建立正常的鼻呼吸,对行使正常的咀嚼、吞咽功能有积极的意义。早期矫治对减少口呼吸继发的错(?)畸形患病率,引导青少年儿童(?)颌面正常发育有积极的意义。
[Abstract]:Objective to investigate the effect of abnormal swallowing on root resorption in patients with abnormal swallowing. The effect of abnormal swallowing on oral respiration was studied in patients with abnormal swallowing. Early correction of malformation provides reference. Methods one: selected patients in the orthodontic department of Beijing Xinhua Hospital from 2007 to 2012. According to the inclusion criteria, 96 patients were selected as study subjects, 48 patients in abnormal swallowing group and 48 patients in normal swallowing group. The age is 13-16 years, Han nationality. All were 16 men and 32 women. All of them were taken by Planmeca Promax panoramic X-ray system of radiology department of Beijing Tongzhou Xinhua Hospital. Using Jiang Ruoping's improved method of root resorption classification, the root resorption grade was evaluated on the whole maxillary surface section. The number of teeth corresponding to the grade of root resorption was combined according to root absorption or not, and chi-square test was performed with SPSS13.0 to compare the difference of tooth number with root resorption between abnormal swallowing group and normal swallowing group. The root resorption of upper and lower incisors, maxillary central incisors, lateral incisors and mandibular central incisors and lateral incisors were compared by rank sum test. Study 2: selected patients in orthodontics department of Beijing Xinhua Hospital from 2007 to 2012. According to the inclusion criteria, 76 patients were selected as the study subjects, including 38 patients in abnormal swallowing group and 38 patients in normal swallowing group (note: study 1 is not intersected with study 2). Age 11-14 years, Han nationality. All were 7 males and 31 females. Using SPSS13.0 software, two groups of data were checked by chi-square test. Result 1. The difference of root resorption between abnormal swallowing group and normal swallowing group was statistically significant (P0.05). 2. Statistical analysis showed that there was significant difference between abnormal swallowing group and normal swallowing group (P0.01). Conclusion 1. Abnormal swallowing is a risk factor for root resorption. 2. Abnormal swallowing is easy to induce oral respiration. 3. Wrong (?) Attention should be paid to the harm of abnormal swallowing in early correction of malformation, and patients should be trained to swallow normally and reduce the probability of root resorption. Correction of abnormal swallowing is also a method of active correction of oral respiration. The establishment of normal nasal respiration is of positive significance for the exercise of normal chewing and swallowing function. Early correction of secondary to oral respiratory reduction (?) Prevalence rate of malformation, leading adolescents and Children (?) Normal maxillofacial development has positive significance.
