早期咬合创伤性牙痛的临床初步分析

Clinical analysis of early toothache caused by tramatic occlusion

目的:分析早期咬合创伤性牙痛的特点,确定早期咬合的概念范围与定义。初步探讨诊断标准及防治方法。材料与方法:对临床诊断早期咬合创伤性牙痛的17例病例进行检查、治疗的临床分析。结果:17例早期咬合创伤性牙痛病例包括前牙3例,前磨牙5例,磨牙9例。表现为不明原因的牙痛,偶有咬合至某一个位置疼痛。有时定位不准确,检查偶有叩痛,经反复检查可查及咬合高点,但X线片检查牙体及牙周膜并未见改变。经调治疗后1周内症状可得到明显的缓解。结论:临床上确实存在单纯因咬合创伤引起的早期牙痛,仔细检查可查到咬合创伤点,但不能查到牙体及牙周组织的损害。在临床应引起重视,早期发现早期治疗,以免引起进一步的损伤。有关单纯性咬合创伤引起早期牙痛的发病原因及机理有待深入研究。

Objective: To observe the characteristics of the toothache that caused by tramatic occlusion and to give theconcept and criteria the diagnosis and treatment of occlusion tramatic toothache. Materials and Methods: The clinicalanalysis of the tramatic toothache in 17 patients were made included 3 incisors, 5 premo lars and 9 molars. Results: In allpatients, the main symptom was toothache caused no reasons except occlusion trama. The occlusion tramatic point can befound. No changes of dentine and periodontal membrane were found. The symptoms were disappeared after adjustmentone week later. Conclusions: There is toothache caused only by tramatic occlusion, but no any defects of enamal andperiodontal membrane. When the tramatic points found, the adjustment should be made as early as possible,which canavoid the further trama to the tooth and periodontal membrane.
