Pathologic tooth migration (PTM) has been defined as tooth displacement that occurs when the balance among the factors that maintain physiologic tooth position is disturbed by periodontal disease. The aim of this cross-sectional epidemiological study was to determine the prevalence of pathologic tooth migration among patients with periodontitis.
Recorded documents of 370 patients (72.4% females, 27.6% males) within the age range of 17 to 70 years (mean 37.77 ± 11.46) were studied. Statistical analysis was carried out using t-test and Chi-square test.
Pathologic migration prevalence was 11.4% (35/314 patients), however, there was no pathologic migration in patients with mild chronic periodontitis. The Chi-square test showed that there was no statistically significant difference between males and females.
The results of this study confirm that pathologic tooth migration is relatively common among periodontal patients and its prevalence is increased by the severity of periodontal disease.
病理性牙齿移位（PTM）被定义为当维持牙齿生理位置的因素之间的平衡因牙周疾病而受到干扰时发生的牙齿移位。这项横断面流行病学研究的目的是确定牙周炎患者中病理性牙齿移位的患病率。
研究了370例年龄在17至70岁（平均37.77±11.46）的患者的记录文件（女性占72.4%，男性占27.6%）。使用t检验和卡方检验进行统计分析。
病理性移位患病率为11.4%（35/314例患者），然而，轻度慢性牙周炎患者中无病理性移位。卡方检验表明，男性和女性之间无统计学显著差异。
本研究结果证实，病理性牙齿移位在牙周病患者中相对常见，且其患病率随牙周疾病的严重程度而增加。
