概括
这项研究发现,虽然下的前后长度在双侧1根下第二 (MnSM) 个体中较短,但没有特定的下特征预测了1根或C形MnSM的发生.
科学领域:
- 牙科 牙科是指牙科的专业.
- 人类学是人类学.
- 人体解剖学 解剖学 解剖学
背景情况:
- 下第二 (MnSM) 根的形态在牙科和正牙实践中至关重要.
- 像1根或C形MnSM这样的变异可以影响治疗计划和结果.
- 了解患病率和相关下部特征对于临床应用至关重要.
研究的目的:
- 在土耳其人群中调查一根和C形下第二牙 (MnSM) 的患病率.
- 分析各种下形状特征,包括宽度,长度和形尺寸.
- 确定这些下部特征与1根/C形MnSM的发生之间的关系.
主要方法:
- 分析了430名土耳其患者 (215名男性,215名女性) 的圆束计算机断层扫描 (CBCT) 图像.
- 确定了1根和C形MnSM的流行率.
- 在双边1根 (1R-1R),单边1根 (1R-2R) 和双边2根 (2R-2R) MnSM的组之间使用统计分析比较了下牙膜膜特征.
主要成果:
- 一根和一根/C形MnSM的患病率分别为12.79%和9.65%.
- 根融合在女性中明显更常见 (p<0.05).
- 与2R-2R组相比,1R-1R组的前后背部长度较短 (p<0.05),其他测量特征没有显著差异.
结论:
- 较短的前后下长度与双边1根的MnSM有关.
- 没有发现任何特定的下形状特征是1根或C形MnSM存在的可靠预测因素.
- 可能需要进一步的研究来确定这些根变异的预测因素.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
