概括
像犬间距离 (ICaD) 这样的面部测量与面部人类测量相关,但性别和年龄会影响这些关系. 这些发现有助于使用面部数据估计牙宽度.
科学领域:
- 牙科 牙科是指牙科的专业.
- 人类学是人类学.
- 医疗成像医学成像
背景情况:
- 大前牙尺寸和面部人类学之间的关系缺乏共识.
- 这些关系中基于年龄和性别的变化没有得到充分记录.
研究的目的:
- 调查犬间距离 (ICaD) 和关键面部人体测量测量 (口腔间距离,口腔间距离,口腔间宽度,口腔间宽度) 之间的相关性.
- 为了确定这些关系是否在不同年龄组和性别之间存在差异.
主要方法:
- 利用了409名参与者的标准化数字图像.
- 使用图像处理软件测量了面部和口腔部分.
- 使用统计分析,包括t测试,ANOVA,皮尔森相关性和线性回归来评估关系和差异.
主要成果:
- 观察到犬间距离 (ICaD) 和两性所有测量的人脸距离之间存在显著差异.
- 所有的面部测量在男性中明显大于女性.
- 在大多数测量中,年龄组在统计学上有显著差异,除了学生之间的距离.
- 在ICaD和所有面部测量 (ICD,IPD,ICW,IAW) 之间发现了显著的正相关性.
- 回归方程在性别和大多数年龄组之间存在显著差异.
结论:
- 像口腔间距离 (ICD),瞳孔间距离 (IPD),口腔间宽度 (ICW) 和口腔间宽度 (IAW) 这样的面部测量不能单独确定口腔间距离 (ICaD).
- 数字成像揭示了面部测量和ICaD之间可能的相关性.
- 结合面部人类学的数学公式可以帮助估计大前牙的宽度,但必须考虑性别和年龄.

01:21Tooth Anatomy

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...

01:15Teeth

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...

01:26Assessment of the Mouth
192
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:14Muscles for Facial Expressions
2.0K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

01:27Cranial Bones: Lateral View
2.2K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
