Abstract

Background: Cracks in teeth are the third most common reason for tooth loss. The primary aim of this study was to identify the patient-specific and tooth-specific characteristics of individuals who presented to a private general dental practice with cracked posterior teeth. The secondary aim was to explore the relationship between the above characteristics and investigate their influence on signs and symptoms.

Materials and methods: A total of 147 records were analysed in terms of patient-specific, tooth-specific and crack-specific characteristics. Initial data analysis involved the use of descriptive statistics and chi-square tests. Stepwise logistic regression was used for model building, and further data analysis was performed using binomial and multinomial logistic regression.

Results: Most cracked teeth were asymptomatic (55.1%) and were not visible before removal of restoration. Unrestored marginal ridges (OR2.89), cracks visible before restoration removal (OR3.04) and cracks involving both the body and cusps of teeth (OR3.11) were associated with cold sensitivity. Not all cracked teeth were positive for the bite test. Molar teeth (OR8.79) and those with amalgam restoration (OR4.81) were associated with intersecting cracks.

Conclusion: The presentation of teeth with cracks in general dental practice seems to differ from that reported in the literature from specialist practice.

后牙裂缝的特征及与症状相关的因素：一项基于实践的横断面观察研究

背景：牙齿裂缝是牙齿脱落的第三大常见原因。本研究的主要目的是确定患者特异性和牙齿特异性特征的个人谁提出了私人一般牙科诊所后牙开裂。第二个目的是探讨上述特征之间的关系，并调查其对体征和症状的影响。材料和方法：对147例病例进行患者特异性、牙齿特异性和裂纹特异性分析。最初的数据分析包括使用描述性统计和卡方检验。采用逐步逻辑回归建立模型，进一步采用二项和多项逻辑回归进行数据分析。结果：大多数牙裂无症状（55.1%），在拔除修复体前不可见。未修复的边缘脊（OR2.89）、修复移除前可见的裂纹（OR3.04）和涉及牙体和牙尖的裂纹（OR3.11）与冷敏感性相关。并不是所有破裂的牙齿在咬合测试中都呈阳性。磨牙（OR8.79）和汞合金修复牙（OR4.81）存在交叉裂纹。结论：牙齿裂缝的表现在一般牙科实践似乎不同于报告的文献从专业实践。
