摘要

观察性研究。样本包括在安德雷斯·贝洛大学(Viña del Mar)牙科诊所进行的TCHC扫描。使用已知人群的公式计算样本量,得到262次扫描。使用Cohen的Kappa系数对检查者进行校准,然后使用I-CAT Vision软件通过成像研究对变量进行分析。对439颗第一和第二上颌磨牙进行了分析。MB2管在第一磨牙中的患病率为63.74%,而在第二磨牙中的发病率为20.04%。男性第一磨牙的患病率(73.86%)高于女性(58.62%),而女性第二磨牙的发病率为15.81%,男性为28.41%。关于年龄,在第一磨牙中,18至40岁的年龄段之间的差异非常显著(66.49%)。根据Vertucci的构型类型,70%的第一磨牙具有II型构型,23.65%具有IV型构型,第二磨牙的结果相似。目前的研究表明,MB2管在分析人群中很常见,尤其是在第一磨牙中,II型配置最为普遍。此外,在18至40岁的男性中观察到更高的患病率。这些发现提供了有关研究人群根系解剖的相关信息,有助于改善治疗效果。

Segundo Conducto Mesiovestibular en Molares Superiores: Prevalencia y Análisis Anatómico Mediante Tomografía Computarizada de Haz Cónico
observational study. The sample consisted of TCHC scans taken at the dental clinic of Universidad Andrés Bello (Viña del Mar). The sample size was calculated using the formula for known population, resulting in 262 scans. The examiners were calibrated using Cohen's Kappa coefficient, then the variables were analyzed through an imaging study using I-CAT Vision software. 439 first and second upper molars were analyzed. The prevalence of MB2 canal in first molars was 63.74 %, while in second molars, it was 20.04 %. The prevalence in first molars was higher in males (73.86 %) than in females (58.62 %), while in second molars, it was 15.81 % in females and 28.41 % in males. Regarding age, in first molars the difference was significant between the age range of 18 to 40 years (66.49 %). Regarding the type of configuration according to Vertucci, 70 % of the first molars had Type II configuration, and 23.65 % had Type IV, with similar results in second molars. The present study demonstrated that MB2 canals are frequent in the analyzed population, especially in first molars, and Type II configuration is the most prevalent. Additionally, a higher prevalence was observed in males and in the age range of 18 to 40 years. These findings provide relevant information about root anatomy in the studied population and can contribute to improving treatment outcomes.
