目的探讨牙隐裂对称性发生的预防措施。方法 64例无牙齿修复史、龋坏的牙隐裂患者,随机分为对照组(32例)和观察组(32例),观察组进行口腔保健和预防性调颌等预防措施,对照组不作预防措施,干预后进行2年随访,对结果进行分析。结果对照组的牙隐裂对称性发生患者21例,占65.6%,观察组为2例,占6.3%,两组比较差异有统计学意义(P<0.05);对侧牙隐裂发生主要于初发牙隐裂11个月内。结论预防性调颌与口腔保健指导,能有效对牙隐裂对称性起预防效果,值得临床进一步推广使用。
Objective To explore the preventive measures of occlusion symmetry. Methods Totally 64 cases of dental caries without tooth restoration and decayed teeth were randomly divided into control group (32 cases) and observation group (32 cases). The observation group was given preventive measures such as oral health care and prophylactic adjustment of the mandible. Preventive measures, follow-up after 2 years of intervention, the results were analyzed. Results In the control group, there were 21 cases (65.6%) of patients with occult fracture symmetry, and 2 cases (6.3%) in the observation group. There was significant difference between the two groups (P <0.05) Primary teeth cracked within 11 months. Conclusion The preventive and maxillofacial guidance and oral health care can effectively prevent the occlusion of teeth from the synergistic effect, which is worth further promotion and use in clinic.
